Description

Extrusion feeding reactor

The invention belongs to the field of coating preparation, in particular to an extrusion feeding type reactor.

Background technique

Coating refers to a continuous film that covers the surface of an object to be protected or decorated and can form a firm adhesion with the object to be coated. The process of paint production is to crush solid pigment particles by external force and disperse them in resin solution or emulsion to form a uniform and fine suspension dispersion. Its production process mainly includes pre-dispersion, grinding and dispersion, paint mixing, purification and packaging and other steps.

In the process of dispersing and mixing paint, some materials are usually added according to the current situation of the paint. However, in the production process of some paints, especially some colored paints, the raw materials usually contain relatively high toxicity. Therefore, the dispersing process is usually carried out under airtight conditions, and the operator usually wears gas-resistant clothing and gas masks when adding raw materials. Less, and for this small amount, the operator has to put on the anti-virus clothing and gas mask again. The operation is relatively cumbersome and has a certain impact on the progress of the entire production.

Contents of the invention

The present invention intends to provide an extrusion feeding type reactor to solve the technical problem that the operator needs to put on the anti-virus clothing and gas mask again when the current coating production needs to add materials, which leads to troublesome operation and affects the production progress.

There is a feeding pipe, and the feeding pipe is provided with a cap; Sealing plate, two sealing plates are respectively hinged on the left and right sides of the feed pipe, both of the two sealing plates are inclined downwards, and the movable sides of the two sealing plates are offset to form an angle towards the upper side, the two sealing plates A compression spring is arranged between the lower side of the sealing plate and the side wall of the feeding pipe corresponding to its position, and the two ends of the two sealing plates are offset against the front and rear sides of the feeding pipe respectively.

The extrusion feed-feeding reactor in this scheme includes the reactor body, which provides a space for dispersion and reaction. The side wall of the reactor body is provided with a feed pipe to facilitate the addition of raw materials. The end is provided with a sealing cover to prevent toxic gases from leaking into the air; the top of the reactor body is provided with a square feeding tube, which is used to hold the materials to be added. Pressing or releasing the air bag can change the air pressure in the feeding tube. There is a feeding tube on the feeding tube. The feeding tube is used to add the material to be added into the feeding tube; there are two sealing plates in the feeding tube, two The sealing plate can separate the upper space of the feeding pipe from the reactor body, preventing the materials in the feeding pipe from falling directly into the reactor body; two sealing plates are respectively hinged on the left and right sides of the feeding pipe, namely Both of the two sealing plates can rotate around the left and right side walls of the feeding pipe, and compression springs are arranged between the lower sides of the two sealing plates and the side walls of the feeding pipe corresponding to their positions, so that the sealing plates Under the action of the upper pressure, the downward rotation can be realized, and the upward rotation can be realized under the action of no upper pressure or lower pressure, so as to realize the opening and closing of the two sealing plates, that is, the opening and closing of the lower end of the feeding pipe The two ends of the two sealing plates are respectively against the front and rear sides of the feed pipe, so as to prevent the material from falling into the reaction kettle from the gap between the two ends of the seal plate and the front and rear sides of the feed pipe. in vivo.

The technical principle of the present invention is: the movable sides of the two sealing plates are offset by the action of the pressure spring, so that the lower end of the feeding pipe is sealed; Inject gas to make the air bag expand and bulge, and seal the air bag mouth; when it is necessary to add materials, squeeze the air bag to reduce the volume of the air bag, and the gas in the air bag enters the feeding tube, thereby increasing the filling tube. Air pressure, the air pressure presses the material downward, and the material also presses the two sealing plates downward, so that the two sealing plates rotate downward, and a gap is exposed between the two sealing plates, and the material can fall through the gap at this time To the reactor body to realize the addition of materials; after the addition is completed, release the air bag, the gas in the feeding pipe enters the air bag, and the air pressure in the feeding pipe decreases, which is lower than the air pressure in the reactor body. At this time, the two pieces are sealed The plates rotate upwards under the gas pressure in the reactor body until the movable sides of the two are offset to realize the closure of the two sealing plates.

The technical effect of the present invention is: in the process of adding materials, the operator does not need to directly contact with the materials to be added, and does not need to open the sealing cover at the feed pipe of the reactor body to contact with the toxic gas inside, so , The operator does not need to put on the anti-virus clothing and gas mask again, the operation is simple, saves time, and ensures the progress of coating production.

The following is a preferred solution based on the above scheme:

Preferred option 1: steel balls are placed above the sealing plate in the feed pipe. When the two sealing plates leak out of the gap, the steel ball can be stuck between the two sealing plates, so that even if the air bag is not continuously squeezed, the two sealing plates can still be opened continuously, so that the materials can enter the reactor body.

Preferred option 2: Based on preferred option 1, there are multiple steel balls. A plurality of steel balls makes the continuous opening effect of the two sealing plates better.

Preferred Solution 3: Based on the preferred solution 2, elastic pads are provided on the movable sides of the two sealing plates. The elastic pad can enhance the sealing performance when the two sealing plates are in contact, preventing the material from directly dripping into the reactor body.

Preferred Solution 4: Based on the preferred solution 3, there are two compression springs arranged between the lower sides of the two sealing plates and the side walls of the feed pipe corresponding to their positions. Two compression springs can make the stress of the two sealing plates more stable.
