Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology for trioxymethylene discharge, and more specifically, to a trioxymethylene hopper arch-breaking device. Background Technology

[0002] 1,3,5-Trioxane is a trimer of formaldehyde. It is a white crystalline solid at room temperature and has a slight formaldehyde odor.

[0003] Currently, it is necessary to use a trioxymethylene silo in conjunction with a screw conveyor to feed material into the metering equipment (the screw conveyor includes a large screw and a small screw; initially, the large screw operates to feed material quickly, and just before reaching the weighing weight, it switches to the small screw to feed material accurately and slowly). When the weighing value of the metering equipment reaches the preset weight, the screw conveyor stops operating, and then the opening of the trioxymethylene packaging bag is placed on the discharge pipe connected to the bottom of the metering equipment. The metering equipment then unloads the material, thus realizing the packaging and storage of trioxymethylene.

[0004] However, during this process, the discharge rate of trioxymethylene is relatively fast and uncontrollable, which can easily cause blockages in the discharge pipe at the bottom of the metering equipment. The current anti-blockage measures are generally to install a stirring rod horizontally in the discharge pipe to break up the blocked trioxymethylene. However, this can only break the arch in one direction and has limited effect on improving the flow of materials. Utility Model Content The purpose of this invention is to solve the problems mentioned in the background art, and to propose a trioxymethylene hopper arch-breaking device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A paraformaldehyde hopper arch-breaking device includes a metering device, the outlet of which is connected to a discharge pipe that matches the packaging bag. It also includes a flexible multi-directional arch-breaking component, which comprises a bending section, a first flange, a drive assembly, a second flange, a stirring shaft, a coupling, a spring, and a vibration motor. The discharge pipe has a bend, and a first flange is welded at an incline on the bend; A second flange, which mates with the first flange, is welded onto the drive assembly; One end of the stirring shaft, which passes through the through hole in the bend and extends obliquely into the discharge pipe, is connected to the drive assembly via a coupling, and both the stirring shaft and the coupling are located inside the first flange and the second flange. The spring located inside the discharge pipe is welded to the other end of the stirring shaft; The vibratory motor is installed on the outer wall of the vertical section of the discharge pipe.

[0006] Furthermore, the drive assembly includes a speed reducer and a servo motor. A second flange is welded to the outer housing of the reducer output end, and the reducer output end is connected to one end of the stirring shaft through a coupling, with the coupling located inside the first flange and the second flange after docking. The servo motor is mounted on the reducer, and the motor shaft of the servo motor is connected to the input end of the reducer.

[0007] Furthermore, at least one set of flexible multi-directional arch-breaking components is provided on the discharge pipe, and the multiple sets of flexible multi-directional arch-breaking components are distributed at intervals.

[0008] Furthermore, the inner wall of the discharge pipe is coated with an anti-stick coating.

[0009] Furthermore, the first flange and the second flange are fastened together by a number of hexagonal bolts, and a metal spiral wound gasket is added to the mating surface of the first flange and the second flange.

[0010] Compared with the prior art, the beneficial effects of this utility model are: Compared to existing technologies, this application significantly reduces the probability of paraformaldehyde blockage in the discharge pipeline by using multiple sets of flexible multi-directional arch-breaking components in combination with a vibration motor. At the same time, the flexible multi-directional arch-breaking components are easy to disassemble for component maintenance. In addition, the tetrafluoroethylene coating applied to the inner wall of the discharge pipeline can effectively discharge the material and reduce the probability of paraformaldehyde adhesion, thus achieving a better arch-breaking effect for metered paraformaldehyde discharge packaging.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figure 1 and Figure 2 As shown, a paraformaldehyde hopper arch-breaking device includes a metering device 1, the outlet of which is connected to a discharge pipe 2 that matches the packaging bag. It also includes a flexible multi-directional arch-breaking component, which includes a bending section 201, a first flange 3, a drive assembly 4, a second flange 5, a stirring shaft 6, a coupling (not shown in the figure), a spring 7, and a vibration motor 8. A bend 201 is formed on the discharge pipe 2, and a first flange 3 is welded obliquely on the bend 201; A second flange 5, which mates with the first flange 3, is welded onto the drive assembly 4; The stirring shaft 6, which passes through the through hole (not shown in the figure, and the through hole is interference fit with the stirring shaft 6) and extends obliquely into the discharge pipe 2, is connected at one end to the drive assembly 4 via a coupling. The stirring shaft 6 and the coupling are both located inside the first flange 3 and the second flange 5. The spring 7, located inside the discharge pipe 2, is welded to the other end of the stirring shaft 6; The vibratory motor 8 is installed on the outer wall of the vertical area of ​​the discharge pipe 2.

[0013] Specific implementation of this utility model solution, such as Figure 1 and Figure 2 As shown, the drive assembly 4 includes a reducer 41 and a servo motor 42. A second flange 5 is welded to the outer casing of the output end of the reducer 41, and the output end of the reducer 41 is connected to one end of the stirring shaft 6 through a coupling, and the coupling is located inside the first flange 3 and the second flange 5 after docking. The servo motor 42 is mounted on the reducer 41, and the motor shaft of the servo motor 42 is connected to the input end of the reducer 41.

[0014] To further improve the arch-breaking effect, the above embodiment is further optimized by installing at least one set of flexible multi-directional arch-breaking components on the discharge pipe 2, and the multiple sets of flexible multi-directional arch-breaking components are spaced apart (see attached instruction manual). Figure 1 The diagram shows two groups.

[0015] In order to reduce the probability of material adhering to the inner wall of the discharge pipe 2, the above embodiment is further optimized by coating the inner wall of the discharge pipe 2 with an anti-stick coating. Specifically, the anti-stick coating is a tetrafluoroethylene coating.

[0016] To achieve a secure connection and effective seal between the two flanges, the above embodiment is further optimized by fastening the first flange 3 and the second flange 5 with several hexagonal bolts, and adding a spiral wound gasket to the mating surface of the first flange 3 and the second flange 5. The hexagonal bolts and the spiral wound gasket are not shown in the figure. The spiral wound gasket can improve the sealing effect after the two flanges are connected, and at the same time balance the uneven force of the multi-point bolt fastening.

[0017] The working process of this utility model: Before unloading, a fixed weight of paraformaldehyde (25KG) is pre-weighed in metering device 1. The servo motor 42 is then started. With the reduction and torque amplification effect of the reducer 41, the motor output torque is amplified to the required value, causing the stirring shaft 6 to rotate at high speed in the discharge pipe 2. The spring 7 also rotates accordingly. Later, when the paraformaldehyde is unloaded from metering device 1, the material flow rate is large, allowing the paraformaldehyde to come into contact with the spring 7. The spring 7 then swings under gravity. The significance of the swing of spring 7 is as follows: (1) The rotational motion of the tilting spring 7 can act simultaneously on the horizontal and vertical directions of trioxymethylene, forming a three-dimensional agitation, effectively solving the problems of arching and stacking. At the same time, compared with the original horizontal rigid agitation, it can expand the vertical arch-breaking area, thus achieving a better arch-breaking effect; (2) The flexible structure of spring 7 can adapt to paraformaldehyde material and is not easily damaged by differences in material hardness. In addition, during high-speed oscillation, it can fling the paraformaldehyde on the surface outward, thus making it less likely for paraformaldehyde to adhere to the surface of spring 7; At the same time, the vibration motor 8 is started to vibrate at high frequency. Combined with the discharge pipe 2 which is pre-coated with tetrafluoroethylene, the probability of blockage in the discharge pipe 2 during the discharge of trioxymethylene is greatly reduced, and the arch breaking effect is good. When it is necessary to clean and maintain the stirring shaft 6 and the spring 7 in the future, simply release the locking of the first flange 3 and the second flange 5 to quickly remove the stirring shaft 6 and the spring 7 from the discharge pipe 2.

[0018] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
