Description

Technical Field

[0001] This utility model relates to the field of solid additive feeding technology, specifically a quick-connect solid additive feeding device. Background Technology

[0002] In the production processes of industries such as chemicals, pharmaceuticals, food, and new materials, the feeding of solid additives, such as catalysts, stabilizers, and powdered raw materials, is a key step in the construction of the reaction system.

[0003] Existing methods for feeding small quantities of solid additives by removing the tank's feeding port can lead to the material easily absorbing moisture, affecting product quality, and in some cases, reacting with air to produce hazardous gases, seriously endangering operator safety. Alternatively, feeding from the glove box results in small quantities with significant residue after passing through the pipeline, also affecting quality. Therefore, a quick-connect solid additive feeding device is proposed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a quick-connect solid additive feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect solid additive feeding device, comprising a first clamping plate and a second clamping plate.

[0006] The inner walls of the first clamping plate and the second clamping plate are fixedly connected with multiple layers of arc-shaped rubber strips. The contact surface of the first clamping plate is provided with a limiting groove, and a sealing strip is fixedly connected in the middle of the limiting groove. The first clamping plate and the second clamping plate are used to clamp the feed pipe at the upper end of the reactor.

[0007] Furthermore, a limiting strip is fixedly connected to the contact surface of the second clamping plate, and the second clamping plate is engaged with the first clamping plate through the limiting strip.

[0008] Furthermore, the first clamping plate and the second clamping plate are provided with corresponding interlocking buckles on their two side edges. The buckles are used to fasten the first clamping plate and the second clamping plate together. The first clamping plate and the second clamping plate are provided with threads on their upper sides, and the bottom box is threadedly connected to the upper sides of the first clamping plate and the second clamping plate.

[0009] Furthermore, a first sealing ring is fixedly connected to the contact surface of the bottom box, the first clamping plate, and the second clamping plate, and a glove box is threadedly connected to the top of the bottom box.

[0010] Furthermore, a second sealing ring is fixedly connected to the contact surface between the glove box and the bottom box.

[0011] Furthermore, an observation window is provided at the front end of the glove box, and a rubber glove is provided below the front end of the glove box.

[0012] Furthermore, a feed hopper is fixedly connected to the middle of the inner wall of the glove box, and a flexible hose is fixedly connected to the lower end of the feed hopper.

[0013] Furthermore, a manual valve is fixedly connected to the middle of the hose.

[0014] Furthermore, the glove box is rotatably connected to a cover plate via a hinge, and a handle is fixedly connected to the top of the cover plate.

[0015] Furthermore, a fixed shaft is fixedly connected to the top of the glove box, and a limit block is rotatably connected to the middle of the fixed shaft. A first vacuum pump and a second vacuum pump are fixedly connected to the upper and lower right sides of the glove box.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting up a first clamping plate, a second clamping plate, and a buckle, the combination of the first clamping plate, the second clamping plate, and the buckle allows for quick clamping of the reactor feed pipe without tools. Installation or disassembly time is reduced to less than 1 / 5 of traditional flange connections, meeting the needs of frequent reactor changes in batch production. Multiple layers of arc-shaped rubber strips on the inner wall enhance its sealing performance. Through the setting of limiting grooves, limiting strips, and sealing strips, the matching positioning of the limiting grooves and limiting strips, combined with the multi-layer sealing of the sealing strip, the first sealing ring, and the second sealing ring, as well as the negative pressure / inert gas protection of the vacuum pump, zero leakage can be achieved. To prevent the spread of toxic, volatile, or dusty materials and avoid health hazards to operators and environmental pollution, an observation window and rubber gloves are installed. The observation window allows for real-time monitoring of the material feeding status, while the rubber gloves, in conjunction with the manual valve, enable "hand-eye coordination" control, precisely adjusting the feeding speed and dosage (error ≤2%). This avoids the problems of excessive material or clumping and blockage caused by traditional open feeding. The feed hopper, with its conical structure, reduces material residue, and the flexible hose buffers the impact of falling material, protecting the stability of the stirring system or existing liquid phase system inside the reactor.

[0027] Please see Figure 1-4This utility model provides a quick-connect solid additive feeding device: a quick-connect solid additive feeding device includes a first clamping plate 1 and a second clamping plate 2. By setting the first clamping plate 1, the second clamping plate 2 and the buckle 6, the device can be quickly clamped to the feed pipe of the reactor without tools. The installation or disassembly time is reduced to less than 1 / 5 of that of traditional flange connections, which is suitable for the needs of frequent reactor changes in batch production. The inner wall has multiple layers of arc-shaped rubber strips 16 to enhance its sealing performance. The inner walls of the first clamping plate 1 and the second clamping plate 2 are both fixedly connected with multiple layers of arc-shaped rubber strips. Article 16, the contact surface of the first clamping plate 1 is provided with a limiting groove 3. By setting the limiting groove 3, the limiting strip 5 and the sealing strip 4, the limiting groove 3 and the limiting strip 5 are positioned together. Combined with the multi-layer sealing of the sealing strip 4, the first sealing ring 8 and the second sealing ring 10, and the negative pressure / inert gas protection of the vacuum pump, zero leakage operation can be achieved, avoiding health hazards to operators and environmental pollution from toxic, volatile or dusty materials. The sealing strip 4 is fixedly connected in the middle of the limiting groove 3. The first clamping plate 1 and the second clamping plate 2 are used to clamp the feed pipe at the upper end of the reactor. The contact surface of the second clamping plate 2 is fixedly connected with the limiting strip 5. The first clamping plate 1 is connected to the limiting strip 5 by engaging. The two sides of the first clamping plate 1 and the second clamping plate 2 are respectively provided with buckles 6 that engage with each other. The buckles 6 are used to fasten the first clamping plate 1 and the second clamping plate 2. The buckles 6 are preferably toggle-type buckles, including a pressing handle with one end hinged to the outer wall of the first clamping plate 1 and a buckle with one end fixed to the outer wall of the second clamping plate 2. By pressing the handle to engage the buckle and pressing down, a strong radial clamping force can be provided to the first clamping plate 1 and the second clamping plate 2 using the lever principle, so as to ensure that they are firmly fixed on the feed pipe. The first clamping plate 1 and the second clamping plate 2 are provided with threads on the top. The bottom box 7 is threadedly connected to the top of the first clamping plate 1 and the second clamping plate 2.

[0028] A first sealing ring 8 is fixedly connected to the contact surface of the bottom box 7 with the first clamping plate 1 and the second clamping plate 2. A glove box 9 is threadedly connected to the top of the bottom box 7. A second sealing ring 10 is fixedly connected to the contact surface of the glove box 9 with the bottom box 7. An observation window 11 is provided at the front end of the glove box 9. By setting the observation window 11 and the rubber glove 12, the observation window 11 can observe the material feeding status in real time. The rubber glove 12, together with the manual valve 15, realizes "hand-eye coordination" control to accurately adjust the feeding speed and dosage (error ≤2%), avoiding the problems of excessive material or clumping and blockage caused by traditional open feeding. A rubber glove 12 is set at the lower front end of the glove box 9. A feed hopper 13 is fixedly connected to the middle of the inner wall of the glove box 9. By setting the feed hopper 13, the conical structure of the feed hopper 13 reduces material residue, and the flexibility of the hose 14 can alleviate the problem. To prevent material from falling and impacting, and to protect the stability of the stirring system or existing liquid phase system inside the reactor, a hose 14 is fixedly connected to the lower end of the feed hopper 13. The lower end of the hose 14 passes through the central through hole of the bottom box 7 and extends into the internal channel formed by the combination of the first clamping plate 1 and the second clamping plate 2, so as to ensure that the material can be directly fed into the feed pipe of the reactor. A manual valve 15 is fixedly connected to the middle of the hose 14. A cover plate 17 is rotatably connected to the glove box 9 via a hinge. A handle 18 is fixedly connected to the top of the cover plate 17. A fixed shaft 19 is fixedly connected to the top of the glove box 9. A limit block 20 is rotatably connected to the middle of the fixed shaft 19. A first vacuum pump 21 and a second vacuum pump 22 are fixedly connected to the upper and lower right sides of the glove box 9. A first interface, a second interface, and an inert gas interface are opened on the box wall of the glove box 9. The first vacuum pump 21 is connected to the internal space of the glove box 9 through the first interface and is used to evacuate the inside of the box to create a negative pressure environment or to prepare for the filling of inert gas. The inert gas interface is used to connect to an external inert gas source to fill the inside of the box with inert gas to protect the materials. The second vacuum pump 22 is connected to the internal space of the glove box 9 through the second interface and is used to remove residual dust in the box and pipes after feeding is completed.

[0029] In use, the first and second clamps are fixed to the feed pipe of the reactor, and the buckle 6 is fastened to ensure that the rubber strip 16 is in close contact with the pipe wall. The bottom box 7 including the first sealing ring 8 and the glove box 9 including the second sealing ring 10 are tightened in sequence. The sealing of each connection is checked. If an inert environment is required, the first vacuum pump 21 is used to evacuate the air and then fill it with inert gas. The cover plate 17 is opened and the solid additive is poured into the feed hopper 13. The cover plate is closed and locked by the limit block 20. The hand is inserted into the glove 12 and the manual valve 15 is operated to open the hose 14 channel. The material falls into the reactor through the feed hopper and hose. The amount added is confirmed through the observation window 11. The manual valve 15 is closed. If cleaning is required, the second vacuum pump 22 is started to remove residual dust. The buckle 6 is loosened to disassemble the device.
