Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical equipment, and particularly relates to a crystal product collecting device for chemical industry. Background Art
[0002] In the chemical industry, after the reaction products are crystallized, they are often separated by a centrifuge. However, when the centrifuge is centrifuged, some of the crystallized products will be thrown out by the centrifuge. This part of the crystallized products is not easy to collect, mainly because there is often protective gas in the reactants, or reaction gas that cannot be discharged into the air.
[0003] To solve this problem, the main solution in the prior art is to collect the crystals thrown out of the centrifuge to the periphery of the centrifuge after the production line is shut down. However, the collection efficiency is low and it affects continuous production. Utility Model Content
[0004] The utility model aims to solve the problems in the prior art and propose a crystal product collection device for chemical industry, which can automatically collect the crystal products dropped by the centrifuge and prevent the gas raw materials involved in the reaction from escaping into the air.
[0005] The technical purpose of this utility model is achieved through the following technical solutions:
[0006] A crystal product collection device for chemical industry comprises a recovery tank and a liquid-sealed tank, wherein a feed pipe is arranged on the top of the recovery tank, a cloth bag is arranged inside the recovery tank, a return pipe is arranged on the top of the liquid-sealed tank, a discharge pipe is arranged on the recovery tank, the discharge pipe is communicated with the liquid-sealed tank, the liquid-sealed tank contains liquid, the pipe mouth of the discharge pipe extends below the liquid level of the liquid, a drain pipe is arranged at the bottom of the liquid-sealed tank, and a valve is arranged on the drain pipe.
[0007] Preferably, a pair of pipe flanges are provided on the discharge pipe, and the recovery tank and the liquid seal tank are detachably connected via the pipe flanges.
[0008] Preferably, an observation port is provided on the top of the recovery tank.
[0009] Preferably, the recovery tank and the liquid seal tank are both made of stainless steel.
[0010] Preferably, the connection position between the discharge pipe and the recovery tank is located on the upper part of the bag.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The utility model provides a crystal product collection device for chemical industry, which can connect the feed pipe on the top of the recovery tank to the centrifuge. After the crystal product dropped by the centrifuge enters the recovery tank, the solid crystal product is separated by a cloth bag, and then the reaction gas is drained into the liquid seal tank. The liquid in the liquid seal tank is used to isolate the gas raw material in the upper part of the liquid seal tank, so as to avoid the reaction gas from flowing back or escaping into the air. On the one hand, the recovery efficiency of the crystal product is improved, and continuous production can also be achieved at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the above drawings:
[0015] 1. Recovery tank; 2. Liquid seal tank; 3. Feed pipe; 4. Cloth bag; 5. Return pipe; 6. Discharge pipe; 7. Liquid; 8. Drain pipe; 9. Valve; 10. Pipe flange; 11. Observation port. DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] As a preferred embodiment of a chemical crystal product collection device of the utility model, Figure 1 As shown, this embodiment provides a crystal product collection device for chemical use, including a recovery tank 1 and a liquid-sealed tank 2, wherein a feed pipe 3 is provided on the top of the recovery tank 1, a cloth bag 4 is provided inside the recovery tank 1, a return pipe 5 is provided on the top of the liquid-sealed tank 2, a discharge pipe 6 is provided on the recovery tank 1, the discharge pipe 6 is communicated with the liquid-sealed tank 2, the liquid-sealed tank 2 contains liquid 7, the mouth of the discharge pipe 6 extends below the liquid level of the liquid 7, a drain pipe 8 is provided at the bottom of the liquid-sealed tank 2, and a valve 9 is provided on the drain pipe 8.
[0018] In some embodiments, in order to facilitate separate manufacturing and on-site assembly, a pair of pipe flanges 10 are provided on the discharge pipe 6 in this embodiment, and the recovery tank 1 and the liquid seal tank 2 are detachably connected through the pipe flanges 10. At the same time, when the recovery tank 1 or one of the liquid seal tanks 2 needs to be repaired or replaced, the recovery tank 1 and the liquid seal tank can be disconnected through the pipe flanges 10, and then the replacement process can be quickly carried out.
[0019] In some preferred embodiments, in order to facilitate observation of the collection of the crystal product in the cloth bag 4 , an observation port 11 is provided on the top of the recovery tank 1 in this embodiment.
[0020] In some embodiments, in order to extend the service life and meet more process requirements, the recovery tank 1 and the liquid sealing tank 2 in this embodiment are both made of stainless steel.
[0021] In some embodiments, the connection position between the discharge pipe 6 and the recovery tank 1 is located on the upper part of the bag 4 .
[0022] It should be noted that in order to completely prevent the crystallized product from entering the discharge pipe 6, the connection position between the discharge pipe 6 and the recovery tank is generally set at the lower part of the cloth bag 4. However, it is found during application that when enough crystallized product is collected in the cloth bag 4, there is a certain positive pressure in the recovery tank, which means that the gas raw material cannot flow quickly from the cloth bag into the lower part of the cloth bag and further enter the liquid seal tank. Therefore, in order to ensure the smoothness of operation, the above embodiment connects the discharge pipe 6 with the recovery tank 1 at the upper part of the cloth bag 4, which can ensure long-term stable operation.
[0023] During operation, the feed pipe 3 is connected to the bottom of the centrifuge. A valve can be set on this part of the pipeline to facilitate the replacement of the bag and the removal of the product collected in the bag. Then the return pipe 5 is connected to the top of the centrifuge. When the crystallized product in the centrifuge is thrown out, it enters the feed pipe and is then separated and collected by the bag. The gas raw materials participating in the reaction enter the liquid seal tank 2 through the discharge pipe 6. Under the liquid seal of the liquid in the liquid seal tank 2, it returns to the centrifuge again through the return pipe 5. The liquid can be pure water.
[0024] When it is necessary to replenish or discharge the liquid in the liquid sealing tank 2, it is done through the drain pipe; for the convenience of observation, a liquid level tube connected to the bottom of the liquid sealing tank is also provided outside the liquid sealing tank 2 to facilitate observation of the liquid level and the position of the outlet pipe 6.
[0025] When the sintered mesh needs to be replaced, the flange blind plate is disassembled from the pipe flange, and the sintered mesh is taken out from the inlet of the pipe body for replacement.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
