Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel equipment technology, and more specifically to a simple reaction vessel feeding self-closing device. Background Technology
[0002] In existing reactors, the feed inlet is generally a circular through hole, through which the material is poured directly. However, during and after the pouring process, the air in the reactor mixes with the dust and volatile organic solvents of the material, which float with the air and are discharged from the through hole. This causes some of the dust from the material to float outside, affecting the surrounding air and resulting in material waste. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a simple reaction vessel feeding self-closing device. When no material is being discharged, it ensures that the front and rear side walls of the material bag are tightly attached, preventing material dust or organic solvents mixed in the air inside the reaction vessel from floating out, thus reducing pollution to the surrounding environment.
[0004] The solution of this utility model to the aforementioned technical problem is:
[0005] A simple reaction axe feeding self-closing device includes a horizontal fixed plate, a central material discharge through hole formed in the middle of the horizontal fixed plate, and a feeding guide sleeve fixed in the middle of the top surface of the horizontal fixed plate, the feeding chamber in the middle of the feeding guide sleeve communicating with the central material discharge through hole.
[0006] A sleeve-shaped material bag is fixed below the horizontal fixing plate. The material bag is connected to the central material discharge hole. Vertical rods are fixed below the horizontal fixing plate on both sides of the material bag. Vertical clamping rods are welded to the bottom ends of the two vertical rods. A gap is formed between the vertical clamping rods and their adjacent vertical rods. The two vertical clamping rods are inserted into the lower left and right sides of the material bag, and the corresponding sides of the material bag are in the gap.
[0007] Multiple elastic rings are fitted onto the material bag and two vertical rods and are elastically tightened.
[0008] An inner guide sleeve is welded and fixed to the inner wall of the central material discharge hole. The lower part of the inner guide sleeve extends out of the bottom surface of the horizontal fixing plate. The upper part of the material bag is fitted onto the outer side of the lower part of the inner guide sleeve. The upper side of the material bag is fixed to the inner guide sleeve by multiple outer pressure plates.
[0009] The top surface of the horizontal fixing plate is fixed with gripping parts on both the left and right sides.
[0010] The bottom surface of the horizontal fixed plate is welded and fixed with an outer guide sleeve, and an inner guide sleeve is inserted into the outer guide sleeve. The tops of the two vertical rods are welded and fixed to the inner sidewalls on the left and right sides of the outer guide sleeve.
[0011] The front and rear sidewalls of the lower part of the bag are in close contact.
[0012] The outstanding effect of this utility model is:
[0013] During material discharge, the material's own weight expands the front and rear side walls of the bag, with the expansion size matching the required amount of material to be discharged. This prevents dust and volatile organic solvents in the material from mixing with the air and floating out. After discharge, the front and rear side walls of the bag remain tightly closed, ensuring that dust and volatile organic solvents mixed in the air inside the reactor do not escape, thus reducing pollution to the surrounding environment.

[0019] For example, see below. Figures 1 to 5 As shown, a simple reaction axe feeding self-closing device includes a horizontal fixed plate 10, a central material discharge through hole 11 formed in the middle of the horizontal fixed plate 10, and a feeding guide sleeve 20 fixed in the middle of the top surface of the horizontal fixed plate 10. The feeding chamber in the middle of the feeding guide sleeve 20 is connected to the central material discharge through hole 11.
[0020] A sleeve-shaped material bag 30 is fixed below the horizontal fixing plate 10. The material bag 30 communicates with the central material discharge hole 11. Vertical rods 1 are fixed below the horizontal fixing plate 10 on both sides of the material bag 30. Vertical clamping rods 2 are welded to the bottom ends of the two vertical rods 1. A gap 3 is formed between the vertical clamping rods 2 and their adjacent vertical rods 1. The two vertical clamping rods 2 are inserted into the lower left and right sides of the material bag 30, and the corresponding sides of the material bag 30 are in the gap 3.
[0021] Multiple elastic rings 40 are fitted onto the material bag 30 and the two vertical rods 1 and are elastically tightened.
[0022] Furthermore, an inner guide sleeve 12 is welded and fixed to the inner wall of the central material discharge through hole 11. The lower part of the inner guide sleeve 12 extends out of the bottom surface of the horizontal fixing plate 10. The upper part of the material bag 30 is fitted onto the outer side of the lower part of the inner guide sleeve 12. The upper side of the material bag 30 is fixed to the inner guide sleeve 12 by multiple outer pressure plates 31. Specifically, the upper side of the material bag 30 is located at the outer wall of the inner guide sleeve 12. The outer pressure plates 31 press against the outer side of the corresponding upper side of the material bag 30. The screw part of the fixing bolt is inserted into the through hole in the middle of the outer pressure plate 31 and the through hole at the upper side of the material bag 30 and screwed into the corresponding screw through hole on the inner guide sleeve 12, so that the upper side of the material bag 30 is clamped between the outer wall of the inner guide sleeve 12 and the corresponding outer pressure plate 31.
[0023] Furthermore, the top surface of the horizontal fixing plate 10 is fixed with gripping parts 4 on both the left and right sides. The gripping parts 4 facilitate manual gripping and handling.
[0024] Furthermore, the bag 30 is a transparent plastic bag, which can be made of plastic materials such as polytetrafluoroethylene, or other materials.
[0025] Furthermore, an outer guide sleeve 13 is welded and fixed to the bottom surface of the horizontal fixed plate 10, an inner guide sleeve 12 is inserted into the outer guide sleeve 13, and the tops of the two vertical rods 1 are welded and fixed to the inner sidewalls on the left and right sides of the outer guide sleeve 13.
[0026] Furthermore, the material bag 30, the two vertical rods 1 and the two vertical clamping rods 2 are fitted with three elastic rings 40 from the middle to the bottom, and are elastically tightened. That is, the lower part of the material bag 30 and the two vertical rods 1 and the two vertical clamping rods 2 are elastically clamped by the three elastic rings 40, so that the front side wall and the rear side wall of the lower part of the material bag 30 are in close contact.
[0027] Furthermore, the feed guide sleeve 20 has a vertical plate body 22 welded and fixed between the two ends of an arc-shaped side plate 21 with a C-shaped cross section. The top of the vertical plate body 22 is formed with an outwardly and upwardly inclined guide plate 23. The top surface of the arc-shaped side plate 21 is inclined downwardly from the end away from the vertical plate body 22 towards the end of the vertical plate body 22.
[0028] In this embodiment, the horizontal fixing plate 10 is pressed against the top surface of the flange connection end at the feed inlet of the reactor. The material bag 30, vertical rod 1, and vertical clamping rod 2 are then inserted into the reactor. The material is then poured into the feed guide sleeve 20. The material enters the material bag 30 along with the feed guide sleeve 20, and its own weight expands the elastic ring 40. At the same time, the lower parts of the two vertical rods 1 and the two vertical clamping rods 2 are brought closer together, thereby expanding the front and rear inner walls of the material bag 30. The size of the expansion is adapted to the amount of material being discharged, so that no dust or volatile organic solvents float in the air and are discharged from the feed guide sleeve 20 during the discharge, reducing pollution and impact on the surrounding air and achieving good environmental protection.
[0029] In this embodiment, the two vertical rods 1 and the two vertical clamping rods 2 are elastic metal rods, such as those made of an iron-nickel based constant elastic alloy. Through the elastic action of the two vertical rods 1 and the two vertical clamping rods 2, the opening and closing of the bottom opening of the bag 30 is controlled. When there is no material, the distance between the lower parts of the two vertical rods 1 and the two vertical clamping rods 2 flattens the bag 30, causing its front and rear walls to fit tightly together, thus closing it. When there is material, its own weight will open the bag 30 as it falls, simultaneously closing the two vertical rods 1 and the two vertical clamping rods 2. The lower parts of rods 2 are brought closer together, increasing the distance between the front and rear walls of the bottom of the bag 30, thus creating an opening. At the same time, the elastic ring 40 is also stretched open. The opening is smaller when less material is fed and larger when more material is fed. When there is no material, the elastic restoring force of the two vertical rods 1 and the two vertical clamping rods 2 causes the lower parts to move away from each other, returning to the initial state. This flattens the bag 30, making its front and rear walls fit tightly and the bag opening closed. This greatly reduces the dispersion of volatile organic solvents and dust when feeding solid materials into the reactor, making it a stepless speed-changing feeding structure that requires no additional power.
[0030] In this embodiment, the elastic ring 40 can be made of rubber band. In order to ensure the tightness of the rubber band and prevent it from falling off, it can be fixed with adhesive at the contact part between the rubber band and the vertical rod 1 to prevent it from falling off due to reduced elasticity during long-term use.
[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
