Description

Technical Field

[0001] This utility model relates to the field of chemical technology, specifically to a continuous drying device for chemical production. Background Technology

[0002] Chemical industry is an abbreviation for "chemical process", "chemical industry", "chemical engineering", etc. All technologies that use chemical methods to change the composition and structure of substances or synthesize new substances belong to chemical production technology, also known as chemical process. The products obtained are called chemical products or chemical products. Chemical drying equipment is a common processing machine in the process of chemical raw material processing.

[0003] For example, application number CN202323135939.2 discloses a continuous drying equipment for chemical production, including a drying drum and a flow-limiting component. The bottom of the drying drum is equipped with a flow-limiting component for controlling the discharge. The flow-limiting component includes a baffle, a discharge port, a moving groove, a pushing rod, and a limiting groove. The discharge port is located on the outer wall of the drying drum corresponding to the baffle, and the moving groove is located on the inner wall of the drying drum corresponding to the baffle. A pushing rod is located at the bottom of the outer wall of the baffle, and a limiting groove is located on the outer wall of the drying drum corresponding to the pushing rod. This utility model, by setting up a flow-limiting component, allows operators to manually pull the pushing rod to control the size of the discharge port, thus controlling the discharge of chemical raw materials from the drying drum. When the loading equipment below the discharge port is full and needs to be replaced, the discharge port can be closed without stopping the drying equipment. The drying equipment can continue to operate and continue drying the chemical raw materials, facilitating operator convenience.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of the lack of a convenient discharge structure, it also fails to discharge the dried chemical raw materials easily after drying. Furthermore, during the discharge process, the drying equipment cannot continue drying new chemical raw materials; that is, it stops working during discharge and cannot continuously dry the raw materials, increasing production costs and time for enterprises. However, during use, when pouring chemical raw materials into the drying tank through the conveyor hopper, the inner diameter of the hopper cannot be adjusted. Therefore, when the user pours a large amount of raw material into it at once, the raw material cannot flow slowly and be fully dried continuously. Repeatedly pouring small batches of chemical raw material into the conveyor hopper not only increases user fatigue but also reduces production efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a continuous drying device for chemical production, which has the advantage of adjustable feeding speed. This solves the problem that when chemical raw materials are poured into the drying barrel through the feeding hopper, the inner diameter of the feeding hopper cannot be adjusted, so when the user pours a large amount of raw materials into it at once, the raw materials cannot flow down slowly and be fully and continuously dried. Furthermore, pouring chemical raw materials into the feeding hopper in small batches multiple times not only increases the user's fatigue but also reduces production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous drying equipment for chemical production, comprising a support platform, a drying drum, a heating device, a conveying hopper, and a discharge pipe. The bottom of the drying drum is fixedly connected to the top of the support platform, the bottom of the heating device is fixedly connected to the right side of the top of the support platform, the output end of the heating device is fixedly connected to the right side of the drying drum via a conduit, the conveying hopper is fixedly connected to the front side of the top of the drying drum, the discharge pipe is fixedly connected to the front side of the top of the support platform, two stacked plates are slidably connected to the inner wall of the conveying hopper, the outer sides of the back of the stacked plates are slidably connected to the two sides of the rear side of the inner wall of the conveying hopper via pins, and a driving mechanism is fixedly connected to the outer sides of the front of the stacked plates.

[0007] In a preferred embodiment of this invention, the driving mechanism includes an outer edge rod, the front of which is fixedly connected to the outer side of the back of the stacked plate, the back of which extends through to both sides of the back of the conveying hopper, a worm gear is fixedly connected to the back of the outer edge rod, and a bidirectional worm is provided on the back of the conveying hopper, with the top two sides of the bidirectional worm meshing with the bottom of the worm gear.

[0008] As a preferred embodiment of this utility model, support blocks are fixedly connected to the rear sides of both sides of the conveying hopper, and both sides of the bidirectional worm gear extend to the outer side of the support blocks.

[0009] As a preferred embodiment of this invention, the inner wall of the support block is movably connected to a ball bearing, and both ends of the surface of the bidirectional worm gear are movably connected to the inner wall of the ball bearing.

[0010] As a preferred embodiment of this invention, a handwheel is fixedly connected to the right side of the bidirectional worm gear.

[0011] As a preferred embodiment of this invention, a U-shaped plate is movably connected to the top of the back side of the conveying hopper, and the U-shaped plate is inclined.

[0012] As a preferred embodiment of this utility model, slots are provided on both sides of the rear side of the top of the U-shaped plate, and an L-shaped rod is slidably connected to the inner wall of the slot. The front of the L-shaped rod is fixedly connected to both sides of the back of the conveying hopper.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up stacked plates, allows for the symmetrical rotation of two stacked plates via a drive mechanism when chemical raw materials are poured into the drying barrel through a hopper. The gap between the two stacked plates, after tilting, controls the speed at which the chemical raw materials fall into the drying barrel. This solves the problem that when chemical raw materials are poured into the drying barrel through a hopper, the inner diameter of the hopper cannot be adjusted, preventing the material from flowing slowly and being continuously dried when a large amount is poured in at once. Furthermore, repeatedly pouring small batches of chemical raw materials into the hopper not only increases user fatigue but also reduces production efficiency. This invention achieves the effect of regulating the material feeding speed.

[0015] 2. This utility model, through the setting of a driving mechanism, allows the user to rotate the two stacked plates in the conveying hopper symmetrically and maintain the angle after stopping when the two stacked plates need to be rotated symmetrically. This drives the two worm wheels to rotate the outer edge rod symmetrically, thereby causing the two stacked plates to rotate symmetrically with the outer edge rod as the axis. This adjusts the gap between the inner sides of the two stacked plates. Then, through the self-locking ability between the worm wheel and the two-way worm, the stacked plates maintain the current angle and are fixed, thus allowing the two stacked plates to stably pass through the gap between the inner sides and controlling the speed at which the raw material enters the drying barrel through the conveying hopper.

[0016] 3. By setting a support block, this utility model provides a support point for the bidirectional worm gear on the conveying hopper, so that the bidirectional worm gear and the worm wheel can be stably meshed and connected, and the user can easily rotate the bidirectional worm gear to drive the worm wheel to rotate symmetrically, thereby improving the user's ease of operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides a continuous drying equipment for chemical production, including a support platform 1, a drying barrel 2, a heating device 3, a conveying hopper 4, and a discharge pipe 5. The bottom of the drying barrel 2 is fixedly connected to the top of the support platform 1, the bottom of the heating device 3 is fixedly connected to the right side of the top of the support platform 1, the output end of the heating device 3 is fixedly connected to the right side of the drying barrel 2 through a conduit, the conveying hopper 4 is fixedly connected to the front side of the top of the drying barrel 2, and the discharge pipe 5 is fixedly connected to the front side of the top of the support platform 1. Two stacked plates 6 are slidably connected to the inner wall of the conveying hopper 4. The outer sides of the back of the stacked plates 6 are slidably connected to the two sides of the rear side of the inner wall of the conveying hopper 4 through a shaft pin, and a driving mechanism 7 is fixedly connected to the outer sides of the front of the stacked plates 6.

[0023] refer to Figure 2 and Figure 3 The drive mechanism 7 includes an outer edge rod 71. The back of the outer edge rod 71 is fixedly connected to the outer side of the front of the stacked plate 6. The back of the outer edge rod 71 extends through to both sides of the front of the conveying hopper 4. A worm gear 72 is fixedly connected to the back of the outer edge rod 71. A bidirectional worm 73 is provided on the back of the conveying hopper 4. The top two sides of the bidirectional worm 73 are meshed with the bottom of the worm gear 72.

[0024] As a technical optimization of this utility model, by setting up a drive mechanism 7, when the user needs to make the two stacked plates 6 in the conveying hopper 4 rotate symmetrically and maintain the angle after stopping, the bidirectional worm gear 73 is rotated to drive the two worm wheels 72 to drive the outer edge rod 71 to rotate symmetrically. Then, the two stacked plates 6 rotate symmetrically with the outer edge rod 71 as the axis, thereby adjusting the gap between the inner sides of the two stacked plates 6. Then, through the self-locking ability between the worm wheel 72 and the bidirectional worm gear 73, the stacked plates 6 maintain the current angle fixed, so that the two stacked plates 6 can stably pass through the gap between the inner sides, controlling the speed at which the raw material enters the drying barrel 2 through the conveying hopper 4.

[0025] refer to Figure 3 Support blocks 8 are fixedly connected to the rear sides of both sides of the conveying hopper 4, and the two sides of the bidirectional worm gear 73 extend to the outside of the support blocks 8.

[0026] As a technical optimization of this utility model, by setting a support block 8, a support point is provided for the bidirectional worm 73 on the conveying hopper 4, so that the bidirectional worm 73 and the worm wheel 72 are stably meshed and connected, and it is convenient for the user to rotate the bidirectional worm 73 to drive the worm wheel 72 to rotate symmetrically, thereby improving the user's ease of operation.

[0027] refer to Figure 3 The inner wall of the support block 8 is movably connected to a ball bearing 9, and the two ends of the surface of the bidirectional worm gear 73 are movably connected to the inner wall of the ball bearing 9.

[0028] As a technical optimization of this utility model, by setting a ball bearing 9, when the user rotates the bidirectional worm gear 73 supported by the support block 8, the ball bearing 9 in the support block 8 rotates together with the bidirectional worm gear 73. Thus, the ball bearing 9 provides a low-friction and smooth rotation axis point for the bidirectional worm gear 73 on the support block 8, thereby improving the stability of the bidirectional worm gear 73 when rotating.

[0029] refer to Figure 2 and Figure 3 A handwheel 10 is fixedly connected to the right side of the bidirectional worm gear 73.

[0030] As a technical optimization of this utility model, by setting a handwheel 10, when the user needs to drive the worm wheel 72 to rotate symmetrically by rotating the bidirectional worm 73, the handwheel 10 can be used as a gripping point for the bidirectional worm 73 to easily achieve the rotation of the bidirectional worm 73, thereby improving the user's work efficiency.

[0031] refer to Figure 2 A U-shaped plate 11 is movably connected to the top of the back of the conveying hopper 4, and the U-shaped plate 11 is inclined.

[0032] As a technical optimization of this utility model, by setting up a U-shaped plate 11, a shielding layer is provided above the worm gear 72 and the bidirectional worm 73, thereby preventing the chemical raw materials from being accidentally spilled onto the worm gear 72 and the bidirectional worm 73 during the process of pouring the chemical raw materials into the conveying hopper 4, and causing them to be contaminated by the lubricating oil on them, so that the spilled chemical raw materials cannot be reused.

[0033] refer to Figure 3 Slots 12 are provided on both sides of the rear side of the top of the U-shaped plate 11. An L-shaped rod 13 is slidably connected to the inner wall of the slot 12. The front of the L-shaped rod 13 is fixedly connected to both sides of the back of the conveying hopper 4.

[0034] As a technical optimization of this utility model, by setting a slot 12 and an L-shaped rod 13, the slot 12 and the L-shaped rod 13 are connected quickly and stably, and the U-shaped plate 11 and the conveying hopper 4 are made easy to disassemble for maintenance of the worm gear 72 and the bidirectional worm 73.

[0035] The working principle and usage process of this utility model are as follows: When the user needs to continuously dry chemical raw materials, according to the particle size of the chemical raw materials and the feeding speed, the double-sided worm gear 73 is rotated by handwheel 10, which drives the two worm wheels 72 to drive the outer edge rod 71 to rotate symmetrically. This causes the two overlapping plates 6 to rotate symmetrically with the outer edge rod 71 as the axis, thereby adjusting the gap between the inner sides of the two overlapping plates 6, effectively changing the size of the discharge port of the conveying hopper 4. After the two overlapping plates 6 are adjusted, the rotation of the double-sided worm gear 73 can be stopped. Then, through the self-locking ability between the worm wheels 72 and the double-sided worm gear 73, the overlapping plates 6 maintain their current fixed angle. Then, the material is discharged through the conveying hopper 4... The L-shaped rod 13 on the upper part of the plate engages with the slot 12 on the U-shaped plate 11 to quickly and stably connect the U-shaped plate 11 to the conveying hopper 4. Then, a shielding layer is established above the worm gear 72 and the bidirectional worm 73. At this point, the heating device 3 can be started to inject hot air into the drying barrel 2. Then, a large amount of chemical raw materials can be poured into the conveying hopper 4 at one time. At this moment, the raw materials will fall slowly into the drying barrel 2 due to the partial obstruction of the two stacked plates 6. Then, they slowly follow the trajectory of the inner wall of the drying barrel 2. After being fully dried, they finally flow slowly to the discharge pipe 5 and are discharged. This completes the drying process of the chemical raw materials, thus having the advantage of adjusting the feeding speed.

[0036] In summary, this continuous drying equipment for chemical production, by setting up stacked plates 6, allows the chemical raw materials to be poured into the drying drum 2 via the hopper 4. The drive mechanism 7 drives the two stacked plates 6 to rotate symmetrically. The gap between the two stacked plates 6 after tilting controls the speed at which the chemical raw materials fall into the drying drum 2. This solves the problem that when chemical raw materials are poured into the drying drum via the hopper, the inner diameter of the hopper cannot be adjusted, preventing the raw materials from flowing slowly and being fully dried continuously when a large amount is poured in at once. Furthermore, repeatedly pouring small batches of chemical raw materials into the hopper not only increases user fatigue but also reduces production efficiency.
