Description

Feeding device for hygroscopic solid powders

technical field

The utility model relates to a feeding device for hygroscopic solid powder.

Background technique

In the prior art, plastic bags or plastic buckets are often used as feed tanks for hygroscopic solid powders, so that the raw materials are easily affected by temperature and humidity and deteriorate due to moisture absorption, and poor sealing will cause dust leakage and pollution, affecting the health of operators. The measurement accuracy of each feeding is low, the workload is heavy, and the time is long, so it is not easy to perform multiple feeding operations.

Contents of the invention

The purpose of this utility model is to provide a kind of feeding device of hygroscopic solid powder, because the steel feeding tank of air isolation is used to replace the plastic bag feeding method in the prior art, so that it has small volume and good sealing performance. It is safe and environmentally friendly, solid raw materials are not easy to absorb moisture, and are not easy to cause dust pollution. At the same time, the feeding amount is accurate, the operation is simple, and the time is short.

The utility model is realized in this way: it includes a raw material tank, a feeding tank, and a reactor, and the raw material tank, the feeding tank, and the reactor are arranged sequentially from top to bottom, and the mouth of the raw material tank is connected with the mouth of the feeding tank through a sealing ring .

The raw material tank is respectively provided with a nitrogen gas inlet, a discharge port and a discharge control valve.

The feed tank is respectively equipped with a nitrogen inlet and outlet, a material inlet and outlet, and a material inlet and outlet control valve.

The reaction kettle is respectively provided with a feed inlet and a feed control valve.

The utility model has the advantages of: due to the use of an air-isolated steel feed tank to replace the plastic bag feeding method in the prior art, it has small volume, good sealing performance, safety and environmental protection, solid raw materials are not easy to absorb moisture, and are not easy to cause dust Pollution, at the same time, the feeding amount is accurate, the operation is simple, and the time is short.

Description of drawings

Accompanying drawing 1 is the superstructure schematic diagram of the present utility model;

Accompanying drawing 2 is a schematic diagram of the lower structure of the utility model.

Detailed ways

As shown in accompanying drawing 1 and accompanying drawing 2, the feeding device of the hygroscopic Mgcl solid powder disclosed by the utility model is mainly composed of a raw material tank 1, _a feeding tank 2, and a reaction kettle 3.

Wherein, the raw material tank 1 is provided with a nitrogen gas inlet 11, a material discharge port 12 and a material discharge control valve 13; 3 is provided with feed inlet 31 and feed control valve 32.

Nitrogen gas inlet 11 is under the situation that raw material tank outlet control valve 13 and feed tank inlet and outlet control valve 23 are all opened, feeds nitrogen to replace the solid powder in raw material tank 1, and avoids that air enters feed tank 2. After the unloading is completed, the nitrogen flow is stopped, and the control valve 13 at the outlet of the raw material tank 1 and the control valve 23 at the inlet and outlet of the feed tank are closed. After removing the bolt at the connection between the outlet 12 of the raw material tank and the inlet and outlet 22 of the feed tank, connect the inlet and outlet 22 of the feed tank 2 with the feed port 31 of the reactor 3, and open the inlet and outlet control valve 23 of the feed tank and the reaction The kettle feed control valve 32 is used to replace the top of the feed tank 2 with nitrogen, and the solid powder is added to the reaction kettle. This process is isolated from the air, avoiding the hygroscopic deterioration of the reaction raw materials. After the feeding is completed, stop the nitrogen flow, close the feed tank inlet and outlet control valve 23 and the reactor feed control valve 32, and remove the bolts from the feed tank inlet and outlet 22 and the reactor feed port 31 to complete a feeding process to the reactor .
