Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding solid materials into a reaction kettle, in particular to a device for feeding solid materials into a reaction kettle. Background Technique
[0002] In recent years, with the improvement of people's living standards, safety production has received more and more attention. Especially in pharmaceutical and chemical production, a large amount of solvents are used. If a solvent is used in a reaction kettle, nitrogen protection must be used during the production process. In this case, open operation cannot be carried out. Therefore, feeding in a fully enclosed manner and with automatic nitrogen replacement and on-line cleaning can well meet these requirements.
[0003] Traditional feeding methods are mostly open feeding. First, the solvent vapor nitrogen in the reaction kettle will overflow during the feeding process or the solid materials will generate dust during the feeding process, and it is impossible to achieve completely enclosed feeding, which will pose great risks to operators and production quality. Conventional feeding methods will make it difficult to clean the feeding device, increasing the workload and difficulty of maintenance work after use. Content of the Utility Model
[0004] To solve the deficiencies mentioned in the above background technique, the purpose of the present utility model is to provide a device for feeding solid materials into a reaction kettle, which realizes fully enclosed feeding through a feeding component and a material storage component, effectively prevents the risks of solvent vapor and solid material dust, ensures the safety of operators and the cleanliness of the production environment, and solves the problems of dust hazards, difficulty in achieving completely enclosed feeding, and difficult cleaning existing in the prior art.
[0005] The purpose of the present utility model can be achieved by the following technical solutions:
[0006] A device for feeding solid materials into a reaction kettle includes a reaction kettle body, a feeding component and a material storage component arranged on the reaction kettle body. An installation plate is fixedly installed on the reaction kettle body. The material storage component includes an external material box. The installation plate is fixedly installed with a first bracket, and the top end of the first bracket is fixedly connected to the external material box. A sealing cover is movably installed on the top of the external material box. A number of prefabricated material boxes are arranged inside the external material box, and multiple prefabricated material boxes are vertically and arrayedly distributed inside the external material box. The prefabricated material box includes a clamping part and a hopper. There are two clamping parts, and the two clamping parts are symmetrically arranged at both ends of the hopper. Through the feeding component and the material storage component, fully enclosed feeding is realized, effectively preventing the risks of solvent vapor and solid material dust, ensuring the safety of operators and the cleanliness of the production environment, and solving the problems of dust hazards, difficulty in achieving completely enclosed feeding, and difficult cleaning existing in the prior art.
[0007] Further preferably, the feeding assembly includes a conveying box and a conveyor belt. The shape of the conveying box is adapted to the shape of the conveyor belt. The bottom end of the external material box is communicated with the top end of the conveying box. A second bracket is fixedly installed on the mounting plate, and the conveying box is fixedly installed at the top end of the second bracket.
[0008] Further preferably, a number of limiting blocks are installed at both the front and rear ends of the conveyor belt. A clamping groove is formed between two adjacent limiting blocks on the left and right. The height of the clamping groove is the same as the height of the clamping portion, and the width of the clamping groove is the same as the width of the clamping portion. The end of the limiting block away from the conveyor belt fits against the inner wall of the conveying box. By making the end of the limiting block away from the conveyor belt fit against the inner wall of the conveying box, it is ensured that the prefabricated material box is always restricted in the clamping groove during the conveying process.
[0009] Further preferably, a blanking channel is communicated with the right side of the bottom of the conveying box. The blanking channel is installed on the top of the reaction kettle body. The distance between the front and rear inner walls of the blanking channel is smaller than the distance between the two clamping portions in the prefabricated material box. Such a design enables the material to naturally fall after the prefabricated material box is flipped at an angle, while the prefabricated material box is still restricted in the conveying box.
[0010] Further preferably, a rotating motor is fixedly installed outside the conveying box. The output end of the rotating motor extends into the conveying box, and the output end of the rotating motor is in transmission connection with the driving roller of the conveyor belt. The conveyor belt is driven by the rotating motor.
[0011] Further preferably, a collecting box is fixedly installed on the top of the mounting plate. The top of the collecting box is communicated with the bottom of the conveying box. The distance between the front and rear inner walls of the collecting box is equal to the distance between the front and rear inner walls of the conveying box. Such a design enables the empty prefabricated material box passing through the collecting box to fall into the collecting box.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
[0024] like Figure 1-4As shown, the solid material feeding device for a reactor comprises a reactor body 1 and a feeding assembly and a storage assembly arranged on the reactor body 1. A mounting plate 2 is fixedly mounted on the reactor body 1. The storage assembly comprises an external material box 3. A first bracket 4 is fixedly mounted on the mounting plate 2. The top end of the first bracket 4 is fixedly connected to the external material box 3. A sealing cover 5 is movably mounted on the top of the external material box 3. A plurality of prefabricated material boxes 6 are arranged inside the external material box 3. The plurality of prefabricated material boxes 6 are vertically arrayed inside the external material box 3. The prefabricated material boxes 6 comprise a clamping portion 7 and a hopper 8. There are two clamping portions 7, and the two clamping portions 7 are symmetrically arranged at both ends of the hopper 8. Fully enclosed feeding is achieved through the feeding assembly and the storage assembly, effectively preventing the risk of solvent vapor and solid material dust, ensuring the safety of operators and the cleanliness of the production environment, and solving the problems of dust hazards, difficulty in achieving completely enclosed feeding, and difficulty in cleaning in the prior art.
[0025] The feeding assembly includes a conveying box 9 and a conveyor belt 10. The shape of the conveying box 9 is adapted to the shape of the conveyor belt 10. The bottom end of the external material box 3 is connected to the top end of the conveying box 9. A second bracket 11 is fixedly installed on the mounting plate 2, and the conveying box 9 is fixedly installed on the top end of the second bracket 11.
[0026] A plurality of limit blocks 12 are installed at both the front and rear ends of the conveyor belt 10. A clamping groove 13 is formed between two adjacent limit blocks 12 on the left and right. The height of the clamping groove 13 is the same as the height of the clamping portion 7, and the width of the clamping groove 13 is the same as the width of the clamping portion 7. The end of the limit block 12 away from the conveyor belt 10 is in contact with the inner wall of the conveyor box 9. By making the end of the limit block 12 away from the conveyor belt 10 in contact with the inner wall of the conveyor box 9, it is ensured that the prefabricated material box 6 is always confined in the clamping groove 13 during the conveying process.
[0027] The right side of the bottom of the conveying box 9 is connected to a material drop channel 14, which is installed on the top of the reactor body 1. The distance between the front and back of the inner wall of the material drop channel 14 is smaller than the distance between the two clamping parts 7 of the prefabricated material box 6. This design allows the material to fall naturally after the prefabricated material box 6 is turned at an angle, while the prefabricated material box 6 remains confined in the conveying box 9.
[0028] A rotary motor 15 is fixedly mounted on the outside of the conveying box 9, and an output end of the rotary motor 15 extends into the interior of the conveying box 9. The output end of the rotary motor 15 is transmission-connected to a driving roller of the conveyor belt 10. The conveyor belt 10 is driven by the rotary motor 15.
[0029] A collection box 16 is fixedly mounted on the top of the mounting plate 2. The top of the collection box 16 is connected to the bottom of the conveying box 9. The distance between the front and back inner walls of the collection box 16 is equal to the distance between the front and back inner walls of the conveying box 9. This design ensures that the empty prefabricated boxes 6 passing through the collection box 16 will fall into the collection box 16.
[0030] Working principle:
[0031] During use, after the prefabricated material box 6 is loaded with solid materials, different prefabricated material boxes 6 can be loaded with different materials to achieve simultaneous feeding of multiple materials, and the external material box 3 is sealed by the sealing cover 5. During feeding, the rotating motor 15 drives the conveyor belt 10. When the empty clamping groove 13 passes the bottom of the external material box 3, the prefabricated material box 6 naturally falls into the clamping groove 13 under the action of gravity, and the prefabricated material box 6 is transported from the external material box 3 to the drop channel 14. As the angle of the prefabricated material box 6 changes, the material eventually falls from the hopper 8, and the solid material is fed into the reactor through the drop channel 14. Then the prefabricated material box 6 continues to be transported until it reaches the top of the collection box 16. At this time, under the action of gravity, the empty prefabricated material box 6 falls into the collection box 16. It is only necessary to clean the prefabricated material box 6 after the feeding is completed, and no residual material will be left in the conveying box 9, which reduces manual operation and improves production efficiency and product quality.
