Description

Technical Field

[0001] The utility model relates to the technical field of reactor equipment, in particular to auxiliary solid-liquid feeding equipment for a reactor. Background Art

[0002] In industrial production, many chemical reactions will use a variety of reactors, and each reactor is responsible for producing a wide variety of products. The production reaction process of many products requires multiple steps to complete, so it is necessary to frequently add auxiliary materials, catalysts, product modifiers and other solid or liquid materials before, after and during the reaction. For the above operation of adding materials during the reaction process, the current production uses the solid feeding port of the reactor itself or a temporary pipe to feed solid materials, while the feeding of liquid materials mostly uses temporary pumping or vacuum suction. Therefore, the reactor will inevitably enter the air during the operation, but the reactions of many products need to be isolated from the air or carried out under gas protection. Therefore, the current feeding method is easy to affect the product quality and the safety of the reaction process.

[0003] In view of this, this application is hereby filed. Utility Model Content

[0004] The technical problem to be solved by the utility model is that in the reaction process of the existing reactor, the feeding of additional reagents is mostly carried out through the solid feeding port of the reactor itself, temporary pipe connection or temporary pumping or vacuum suction. Air will inevitably enter the reactor, affecting the product quality and the safety of the reaction process. The utility model aims to provide an auxiliary solid-liquid feeding equipment for the reactor, which can perform sealed feeding or feeding under atmosphere protection according to the needs of feeding. At the same time, by setting up multiple feeding cavities, it can avoid that solid and liquid materials share a feeding channel, resulting in a large amount of solid material adhering to the inner wall of the cylinder, thereby avoiding inaccurate feeding.

[0005] The utility model is realized by the following technical solutions:

[0006] An auxiliary solid-liquid feeding device for a reactor, comprising a feeding cylinder, a mounting tube is provided at the bottom of the feeding cylinder, and the mounting tube is used for detachably mounting at a feeding port of the reactor;

[0007] A plurality of partition plates are arranged inside the feeding cylinder, and the partition plates divide the inside of the feeding cylinder into a plurality of feeding cavities, and the bottoms of the feeding cavities are all connected to the installation pipe;

[0008] A sealing plate is provided on the top of the feeding cylinder, and a plurality of feeding ports are provided on the sealing plate, and each of the feeding ports is connected to the feeding cavity in a one-to-one correspondence;

[0009] The sealing plate is also provided with a vent.

[0010] The utility model can perform sealed feeding or feeding under atmosphere protection according to the needs of feeding, and at the same time, by providing multiple feeding cavities, it can avoid solid material and liquid material sharing a feeding channel, resulting in a large amount of solid material adhering to the inner wall of the cylinder, thereby avoiding inaccurate feeding.

[0011] When the auxiliary solid-liquid feeding equipment of the utility model is in use, firstly, the installation tube is fixedly installed with the feeding port of the reactor, and when other process raw materials are added without atmosphere protection or sealed feeding, solid materials or liquid materials can be respectively fed from different feeding ports, and the raw materials enter the reactor along the feeding cavity; when sealed feeding or atmosphere protection feeding is required, the raw materials are first added to the feeding cylinder, and then the inside of the feeding cylinder is vacuumed or a protective atmosphere is passed through the vent, and then the raw materials are fed into the reactor through the installation tube, so as to avoid the influence of air on the raw materials.

[0012] If solid material is fed after liquid raw material is fed, the solid material is likely to adhere to the inner wall of the cylinder due to the residual liquid on the inner wall of the tube. Therefore, the utility model provides multiple feeding cavities to separate the solid material and liquid material and use different cavities for feeding. This can avoid the solid material and liquid material sharing the same feeding channel, which will cause a large amount of solid material to adhere to the inner wall of the cylinder, resulting in inaccurate feeding.

[0013] In a specific embodiment, a ventilation cavity is coaxially arranged at the center of the feeding cylinder, and partition plates are sequentially arranged between the inner wall of the feeding cylinder and the outer wall of the ventilation cavity along the circumferential direction, and the ventilation cavity and the vent are connected to each other. The utility model sets a ventilation cavity separately, so that whether it is vacuuming or introducing protective gas, it will not affect the raw materials added, and the raw materials are prevented from being sucked or blown up.

[0014] In a specific embodiment, a feed extension tube is coaxially arranged in the installation tube, the upper end of the feed extension tube is connected to the feeding cavity, and the lower end extends into the middle of the reactor. The utility model can prevent material loss when feeding solid materials by arranging a feed extension tube whose length extends below the reaction liquid level of the reactor.

[0015] In a specific embodiment, the bottom of the feeding cylinder is a conical structure.

[0016] In a specific embodiment, an air hole (10) communicating with the feeding cavity is provided on the upper side wall of the ventilation cavity.

[0017] In a specific embodiment, the bottom of the ventilation cavity is closed, and the upper side wall of the ventilation cavity is a mesh structure.

[0018] The utility model seals the bottom of the ventilation cavity, so when vacuuming or introducing protective gas, the gas is communicated with the feeding cavity through the mesh holes on the upper side wall of the ventilation cavity, which can further prevent the material at the bottom of the feeding cylinder from being sucked or blown up when vacuuming or introducing protective gas.

[0019] In a specific embodiment, a solenoid valve is installed at the connection between the upper end of the feed extension tube and the bottom of the feed cylinder, and a valve is also installed at each feed port to facilitate operation.

[0020] In a specific embodiment, the portion of the feed extension tube that exceeds the installation tube gradually increases in diameter from top to bottom. The diameter of the lower end of the feed extension tube gradually increases, which can increase the direct contact area between the material and the reaction liquid during the feeding process and prevent the material from quickly mixing with other reaction materials.

[0021] In a specific embodiment, the sealing plate is detachably connected to the feeding cylinder, which can facilitate cleaning and maintenance of the feeding cylinder.

[0022] In a specific embodiment, the feeding cylinder, the mounting pipe, and the partition plate are all made of stainless steel, which can ensure the high temperature corrosion resistance of the feeding equipment.

[0025] 2. The auxiliary solid-liquid feeding equipment for a reactor provided by the embodiment of the utility model, when sealed feeding or atmosphere protection feeding is required, the raw materials are first added to the feeding cylinder, and then the inside of the feeding cylinder is evacuated or a protective atmosphere is passed through the vent, and then the raw materials are fed into the reactor through the installation pipe, thereby avoiding the influence of air on the raw materials;

[0026] 3. The auxiliary solid-liquid feeding equipment for the reactor provided by the embodiment of the utility model has a separate ventilation cavity, so that whether it is vacuuming or introducing protective gas, it will not affect the raw materials added, and the raw materials are prevented from being sucked or blown up;
