Description

A continuous liquid supply device

technical field

The utility model belongs to the field of mechanical equipment manufacturing, in particular to the manufacturing of water circulation equipment.

Background technique

Adding additives to water circulation systems is a widely used process that often requires a continuous supply of additives.

A traditional continuous liquid supply system includes a stirring tank 1, an auxiliary stirring tank 6, a main liquid supply pipe 2 connected to the bottom of the stirring tank 1, a main liquid supply valve 3 connecting the main liquid supply pipe 2 and a water pump 10, and an auxiliary stirring tank 6 The auxiliary liquid supply pipe 4 connected to the bottom communicates with the auxiliary liquid supply pipe 4 and the auxiliary liquid supply valve 5 of the water pump 10 , and the outlet pipe 12 connected with the outlet of the water pump 10 .

Mixing tank 1 and auxiliary mixing tank 6 prepare additives. Stirring tank 1 or auxiliary stirring tank 6 cannot provide additives (ie external liquid supply) when preparing additives. In order to achieve continuous supply of additives, the mixing tank 1 and the auxiliary mixing tank 6 alternately prepare additives and alternately supply liquid to the outside. By separately opening the main liquid supply valve 3 or the auxiliary liquid supply valve 5, it is ensured that a tank can supply liquid to the water circulation system at any time.

Since the time for preparing additives is shorter than the liquid supply time for a single tank, the volume of the auxiliary mixing tank 6 can be relatively small, and the continuous liquid supply can be ensured during the time for preparing additives in the mixing tank 1 .

The traditional liquid supply device needs to install a stirring mechanism in both tanks, which is relatively complicated and relatively high in cost.

Utility model content

The purpose of the utility model is to provide a continuous liquid supply device with simple structure and low cost.

The utility model comprises a stirring tank 1, a main liquid supply pipe 2 connected to the bottom of the stirring tank 1, a main liquid supply valve 3 connecting the main liquid supply pipe 2 and the water pump 10, an outlet pipeline 12 connected with the outlet of the water pump 10, and It is characterized in that it also includes a storage tank 7, a connecting pipe 8 located at the bottom of the mixing tank 1 and the storage tank 7 connecting the two, a stop valve 9 on the connecting pipe 8, and an auxiliary liquid supply pipe located at the bottom of the liquid storage tank 7 4. Connect the auxiliary liquid supply pipe 4 and the auxiliary liquid supply valve 5 of the water pump 10 .

This device uses the storage tank 7 to replace the traditional auxiliary mixing tank 6, which saves a set of mixing mechanism, and has a simpler structure and lower cost.

The stirring tank 1 and the storage tank 7 can also be located in the same container and separated by a partition 11, which can further reduce the cost.

Description of drawings

In order to further illustrate the utility model in conjunction with the embodiments, the accompanying drawings used in the embodiments of the utility model are introduced as follows:

Accompanying drawing 1, schematic diagram of traditional continuous liquid supply device;

Accompanying drawing 2, the schematic diagram of embodiment 1 of the continuous liquid supply device provided by the utility model;

Accompanying drawing 3, the schematic diagram of embodiment 2 of the continuous liquid supply device provided by the utility model.

Detailed ways

Example 1:

See Figure 2, the main liquid supply pipe 2 is connected to the bottom of the mixing tank 1, the two ends of the main liquid supply valve 3 are respectively connected to the main liquid supply pipe 2 and the water pump 10, and the connecting pipe 8 is connected to the mixing tank 1 and the storage tank respectively. 7 lead out from the bottom and connect the two; the storage tank 7 is at the same height as the mixing tank 1, and there is a shut-off valve 9 on the communication pipe 8, and the auxiliary liquid supply pipe 4 and the water pump 10 at the bottom of the storage tank 7 pass through the auxiliary liquid supply valve 5 Connected, the outlet pipe 12 connected with the outlet of the water pump 10 leads to the water circulation system.

The working process of the device is as follows:

(1) When starting, first close the main liquid supply valve 3, the auxiliary liquid supply valve 5 and the shut-off valve 9, and prepare additives in the mixing tank 1;

(2) After the additive preparation is completed, open the main liquid supply valve 3, supply liquid from the mixing tank 1 to the water circulation system through the main liquid supply pipe 2, the main liquid supply valve 3, the water pump 10 and the outlet pipeline 12, and open the stop valve 9 at the same time , quickly inject the additive into the storage tank 7 in a short period of time, and close the shut-off valve 9 when the liquid levels of the storage tank 7 and the mixing tank 1 are equal;

(3) When the additive in the mixing tank 1 is used up, close the main liquid supply valve 3, open the auxiliary liquid supply valve 5, and pass through the auxiliary liquid supply pipe 4, the auxiliary liquid supply valve 5, the water pump 10 and the outlet from the storage tank 7 The pipeline 12 supplies liquid to the water circulation system, and at the same time, the additive is prepared in the mixing tank 1;

(4) When the additive in the storage tank 7 is used up, the additive in the mixing tank 1 has been prepared.

Steps (2) to (4) are repeated, and liquid is supplied sequentially from the stirring tank 1 and the storage tank 7 respectively.

In this working process, a set of stirring device is omitted, which saves cost while ensuring continuous liquid supply.

Example 2:

See accompanying drawing 3, mixing tank 1 and storage tank 7 are located in the same container, and are separated by partition 11, and other structures are the same as embodiment 1.

The working process of this device is also identical with embodiment 1. The advantage is that the mixing tank and the storage tank are closely combined, the structure is more compact, and the cost is lower.
