Description

Microwave digestion tank rack

technical field

The invention belongs to a reagent placement rack, in particular to a microwave digestion tank placement rack.

Background technique

Microwave digestion technology is a common sample processing technology in analytical chemistry, and has been widely used in biology, geology, metallurgy, coal, medicine, food and other fields. When using a microwave digestion instrument to process samples in batches, it is necessary to select a suitable microwave digestion tank rack and place multiple microwave digestion tanks on the rack to prevent collisions when moving microwave digestion tanks or adding acid to the tank. Invert the digestion tank, causing the acid to leak out.

The Chinese invention patent with the authorized notification number CN 203785947U discloses a microwave digestion tank rack. The rack includes a box body, and a number of spaces are evenly divided in the box body. The size of the space is adapted to the shape of the microwave digestion tank. , There is a sealing device at the joint between the box body and the box cover, a sealing groove on the upper frame of the box body, a pipe joint at the bottom of the box body, and a stop valve connected to the pipe joint. The diameter of the lid of the microwave digestion tank on the market is generally larger than the outer diameter of the tank. In order to ensure that multiple microwave digestion tanks can be placed in the rack, the size of the space in the rack box of this patent must be the same as that of the microwave digestion tank. Only when the tank cover size matches can the microwave digestion tank equipped with the tank cover be placed in the space in the box. If the microwave digestion tank is placed in this space, due to the small outer diameter of the tank, the microwave digestion tank is It is unavoidable that there will be slight shaking in the space. If the lid of the tank is opened on this shelf, it is prone to unstable force application, which will cause the acidic liquid in the tank to splash out and cause injury to the operator.

After using the microwave digestion tank, drying is usually used to dry the cleaned microwave digestion tank. The mouth of the microwave digestion tank placed in the oven is upward, and water is easy to accumulate in the tank, which will take a long time to dry. , Impurities may also fall into the microwave digestion tank during the long-term drying process. When the microwave digestion tank is used again to process samples, impurities will be introduced, which will affect the accuracy of the analysis and measurement results. The placement rack provided by this patent cannot solve the problems of water accumulation in the tank and easy contamination of the tank body when the microwave digestion tank is dried.

Detailed ways

A microwave digestion vessel rack of the present invention will be described in detail below in conjunction with the accompanying drawings and the embodiments:

As shown in Figures 1 to 5, a shelf for microwave digestion tanks includes a base plate 2 and two side plates 3 located on the left and right sides of the base plate 2 and fixed vertically to the base plate 2. The draining support plate 5, the positioning plate 6 and the rubber ring 7 arranged between the two side plates 3 from top to bottom;

A plurality of evenly distributed limiting grooves 8 are formed on the top surface of the bottom plate 2;

The inner wall of the side plate 3 forms a horizontal upper groove 9 and a lower groove 10 from top to bottom;

The top surface of the positioning plate 6 forms a plurality of evenly distributed through holes 11, and the two ends of the positioning plate 6 are inserted into the lower groove 10;

Horizontal convex strips 12 are formed on both side walls of the draining tray 5, and the convex strips 12 are snapped into the upper groove 9;

The rubber ring 7 is inserted into the through hole 11, and the upper end of the rubber ring 7 forms a plurality of tongue-shaped elastic protrusions 14 along the circumference; the protrusions 14 are used to generate friction, so that the microwave digestion tank will not go up and down after being inserted into the circular through hole. and rotational movement.

A handle 4 is installed in the middle of the outer side of the side plate 3 .

The cross-section of the upper groove 9 is trapezoidal, and the width of the bottom of the groove is greater than the width of the opening; the cross-section of the lower groove 10 is rectangular.

The limit slots 8 are circular, and the number of the limit slots 8 and the through holes 11 are the same and one-to-one correspondence, and the centers of the two are on the same axis.

The shape and size of the protruding strip 12 match with the upper groove 9 .

The bottom surface of the draining tray 5 is concave to form a water collection tank 13 .

Number marks are engraved beside the through hole 11 .

The upper end of the rubber ring 7 forms an upper convex edge 15, and the lower end surface forms a lower convex edge 16, and the upper convex edge 15 is placed above the upper top surface of the positioning plate 6, and the lower convex edge 16 is placed below the lower bottom surface of the positioning plate 6; 7. The inner diameter is equal to the outer diameter of the microwave digestion tank body.

The included angle between the protrusion 14 and the upper convex edge 15 is an obtuse angle, and a plurality of tongue-shaped elastic protrusions 14 are radially distributed, and the protrusions 14 are bendable.

One side port of said upper groove 9 runs through the edge of side plate 3, and the distance between the other side port and the edge of side plate 3 is greater than 0.5 cm, which improves the fixability of upper groove 9 to draining supporting plate 5.

The shelf of the microwave digestion tank is made of corrosion-resistant inert plastic.

The usage method of the present invention:

When using the present invention to place and fix the microwave digestion tank, the tank body is sequentially inserted into the rubber ring 7 in the circular through hole 11 on the positioning plate 6 and the circular limiting groove 8 on the bottom plate 2 . The radially bendable tongue-shaped elastic protrusions 14 provided on the rubber ring 7 can provide enough friction when the tongue-shaped elastic protrusions 14 are in contact with the outer wall of the tank, so that the microwave digestion tank will not go up and down after being inserted into the rubber ring 7 and rotating movement, to ensure that the microwave digestion tank is stably fixed, which is convenient for adding chemical reagents to the tank, opening the tank cover and other operations. After inserting and fixing the batch of microwave digestion tanks, the handle 4 on the side plate 3 can be held by hand to facilitate the overall movement of the batch of microwave digestion tanks.

After the microwave digestion tank is cleaned, when using the present invention to drain water, the tank body is sequentially inserted into the rubber ring 7 in the circular through hole 11 on the positioning plate 6 and the circular limiting groove 8 on the bottom plate 2, and then the draining supporting plate 5 The protruding strips 12 at both ends are inserted into the upper groove 9 on the side plate 3, and finally the whole frame is placed upside down. With the help of the friction force generated by the tongue-shaped elastic protrusion 14 and the tank body, it is ensured that the tank body will not fall when it is turned upside down with the rack. In the sump 13 on the top, the leached liquid has been prevented from dripping on the test table. The mouth of the tank is facing down to prevent impurities from falling into the tank, and the mouth of the tank is suspended to ensure the cleanliness of the microwave digestion tank.
