Description

Technical Field

[0001] This utility model relates to the field of pneumatic transmission device technology, specifically to a pneumatic transmission device with a temperature control structure. Background Technology

[0002] Pneumatic conveying devices are mechanized equipment that uses airflow to transport powdery, granular, or small lump materials in closed pipelines. Positive or negative pressure airflow generated by a fan suspends the material and causes it to move directionally with the airflow. They are widely used in raw material conveying in industries such as chemical, food, and pharmaceutical. Their core feature is achieving dust-free, efficient, and long-distance automated material transport.

[0003] Traditional pneumatic conveying devices do not have the function of controlling the temperature of materials. For example, the temperature of some powdered chemical raw materials is usually controlled within the range of 180 to 200 degrees Celsius. Pneumatic conveying devices mostly use stainless steel pipes for conveying, and the ambient temperature can easily affect the temperature of the material, which can easily lead to the deterioration of the material during the conveying process. Therefore, those skilled in the art provide a pneumatic conveying device with a temperature control structure to solve the problems mentioned in the background art. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution: a pneumatic transmission device with a temperature control structure, including a base 1, a fan device 11 fixedly installed on the top of the base 1, a fan controller 12 fixedly installed on the front of the fan device 11, a connecting pipe 13 fixedly connected to the exhaust end of the fan device 11, a transmission pipe 14 detachably connected to the right side of the connecting pipe 13, a temperature control mechanism 2 provided on the outer wall of the transmission pipe 14, and a feeding mechanism 3 provided on the top of the base 1.

[0022] The temperature control mechanism 2 includes a first splicing sleeve 21 and a second splicing sleeve 22. The first splicing sleeve 21 and the second splicing sleeve 22 are detachably connected to the outer wall of the transmission pipeline 14. Electric heating elements 23 are fixedly installed on the inner walls of both the first splicing sleeve 21 and the second splicing sleeve 22. Insulation layers 24 are fixedly connected to the inner walls of both the first splicing sleeve 21 and the second splicing sleeve 22. A small controller 25 is fixedly installed on the outer wall of the first splicing sleeve 21. A connecting rope 26 is fixedly connected to the outer wall of the small controller 25. An externally mounted temperature transmitter 27 is fixedly installed at the end of the connecting rope 26 away from the small controller 25. The externally mounted temperature transmitter 27 is movably connected to the outer wall of the transmission pipeline 14. The actual length of the transmission pipeline 14 is determined based on the internal dimensions of the plant area. Designed for actual use environment, the temperature control mechanism 2 consists of multiple units, evenly distributed on the outer wall of the transmission pipe 14, with a spacing of one meter. The external temperature transmitter 27 is fixed to the outer wall of the transmission pipe 14 by adhesive or clamping. It senses the surface temperature through heat conduction and converts it into an electrical signal output. The signal is fed back to the mini controller 25. When the temperature is lower than the preset value, the mini controller 25 controls the heating element 23 to work, heating the transmitted material through the transmission pipe 14. When the temperature is higher than the preset value, the mini controller 25 controls the heating element 23 to stop working, thus realizing the temperature control function, ensuring that the material is within a suitable temperature range, and avoiding the problem of some materials easily deteriorating during the transmission process.

[0023] It is worth noting that the electric heating component 23, the miniature controller 25, and the external temperature transmitter 27 in this solution are commercially available devices that can be purchased by those skilled in the art. No structural modifications have been made to these devices in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them proficiently. Thus, this paper will not elaborate on them further. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit in this paper is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not require protection for the algorithm and circuit technology.

[0024] It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0025] As one implementation method in this embodiment, please refer to Figure 2As shown, a protruding plate 28 is fixedly installed on the outer wall of splicing sleeve 1 21. A connecting rod 281 is welded to the outer wall of the protruding plate 28. A kit 282 is slidably connected to the outer wall of the connecting rod 281. The kit 282 is fixedly installed on the outer wall of splicing sleeve 22. When installing splicing sleeve 1 21 and splicing sleeve 22, pull splicing sleeve 1 21 and splicing sleeve 22 in a direction away from each other. Then, fit splicing sleeve 1 21 and splicing sleeve 22 onto the outer wall of the transmission pipe 14 to complete the splicing.

[0026] As one implementation method in this embodiment, please refer to Figure 2 As shown, an assembly bolt is threaded onto the outer wall of the kit 282. The threaded end of the assembly bolt movably abuts against the outer wall of the connecting rod 281. After the splicing sleeve 1 21 and splicing sleeve 22 are spliced ​​on the outer wall of the transmission pipe 14, the assembly bolt on the kit 282 is tightened to complete the positioning of the splicing sleeve 1 21 and splicing sleeve 22.

[0027] As one implementation method in this embodiment, please refer to Figure 3 As shown, the feeding mechanism 3 includes a support leg 31, which is fixedly installed on the top of the base 1. A sleeve 32 is fixedly installed at the end of the support leg 31. A vibration motor 33 is fixedly installed on the outer wall of the sleeve 32, and a storage bin 34 is fixedly installed on the inner wall of the sleeve 32. Through the cooperation of the support leg 31 and the sleeve 32, the storage bin 34 can be supported. By controlling the vibration motor 33 to work, the storage bin 34 can be driven to vibrate as a whole, thereby improving the smoothness of material feeding. When in use, the material is added into the inner cavity of the storage bin 34 in advance.

[0028] As one implementation method in this embodiment, please refer to Figure 3 As shown, a first valve 35 is fixedly connected to the bottom of the storage silo 34. A metering silo 36 is fixedly connected to the bottom of the first valve 35. A second valve 39 is fixedly connected to the bottom of the metering silo 36. A rubber pipe 391 is fixedly connected to the bottom of the second valve 39. The rubber pipe 391 is fixedly connected to the top of the connecting pipe 13. A transparent cylinder 37 is fixedly installed in the middle of the metering silo 36. Scale lines 38 are coated on the outer wall of the transparent cylinder 37. The transparent cylinder 37 is made of transparent plastic. Pneumatic conveying is often used to send materials into a larger intermediate silo or buffer silo. Downstream processes... The pneumatic conveyor will precisely retrieve or measure materials from this silo. At this time, the goal of the pneumatic conveyor is to maintain a certain amount of material in the silo (it cannot be empty or severely overflowing). The conveying volume is a concept of "batch" or "cart". It is not necessary to precisely control the specific weight of each transfer, as long as the material level is maintained within a reasonable range. If batch conveying is required, first control valve 35 to open and observe the approximate amount of material added to the metering silo 36 from the scale line 38. Then close valve 35 and control valve 39 to open, which can realize the function of batch conveying of materials.

[0029] As one implementation method in this embodiment, please refer to Figure 4 As shown, a partition 341 is fixedly installed on the inner wall of the storage bin 34, and a stainless steel mesh cylinder 342 is fixedly connected to the bottom of the partition 341. A support plate 343 is fixedly installed on the inner wall of the storage bin 34 near the top. Through the design of the stainless steel mesh cylinder 342, the material can be filtered, and larger particles can be filtered out in the inner cavity of the storage bin 34, avoiding the problem that large particles can easily cause blockage in the subsequent pipeline.

[0030] As one implementation method in this embodiment, please refer to Figure 4 As shown, an extension rod 344 is slidably connected to the inner wall of the support plate 343. A handle 345 is fixedly installed on the top of the extension rod 344, and a crushing rod 346 is fixedly installed on the outer wall of the extension rod 344 near the bottom. The user can pull the extension rod 344 up and down and rotate it from the handle 345 to drive the crushing rod 346 to move in the inner cavity of the stainless steel mesh cylinder 342, which can crush the lumps of material and facilitate the smooth passage of the material.

[0031] Working principle: When in use, the actual length of the transmission pipeline 14 is designed according to the actual use environment inside the factory area. The material is added into the inner cavity of the storage bin 34 in advance. If quantitative material transfer is required, first control the opening of valve 35 and observe the amount of material added into the metering bin 36 from the scale line 38. After reaching a certain amount, close valve 35, then control the opening of valve 39 and control the operation of the blower device 11 to deliver gas into the inner cavity of the connecting pipeline 13. The gas flows through the transmission pipeline 14 and carries away the material, thus realizing the function of quantitative material transfer.

[0032] The external temperature transmitter 27 senses the surface temperature of the transmission pipe 14 through heat conduction and converts it into an electrical signal output. The signal is fed back to the mini controller 25. When the temperature is lower than the preset value, the mini controller 25 controls the heating element 23 to work and heat the material being transported through the transmission pipe 14. When the temperature is higher than the preset value, the mini controller 25 controls the heating element 23 to stop working, thus realizing the temperature control function.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
