Description

Technical Field

[0001] This utility model relates to the field of chemical reagent processing technology, specifically to a feeding device for a dryer used in chemical reagent processing. Background Technology

[0002] In the field of chemical reagent processing, the drying of solid chemical reagents is a key step to ensure the purity, stability and subsequent use effect of the reagents. As the starting step of the drying process, the rationality and efficiency of the feeding process directly affect the overall drying quality and production efficiency. Currently, the feeding methods of chemical reagent dryers used in the industry are still mainly traditional manual feeding or simple mechanical feeding.

[0003] Traditional manual feeding methods rely on operators to manually add solid chemical reagents into the dryer. This is not only labor-intensive and costly, but also prone to problems because manual feeding cannot accurately control the reagent flow rate. This can easily lead to overfeeding and reagent accumulation in the dryer, making it difficult for the bottom reagents to fully contact the heat, resulting in uneven drying and a significant decrease in drying efficiency. At the same time, insufficient feeding will lead to low utilization of the dryer's internal space, wasting energy and production time. Furthermore, it is impossible to screen chemical reagents during the feeding process, which affects the quality of subsequent processing.

[0004] More importantly, some solid chemical reagents are prone to generating dust during the feeding process. Traditional manual feeding lacks effective safety protection, and dust will spread around the feed inlet. When the dust encounters static sparks, mechanical friction sparks generated by equipment operation, or the high temperature environment inside the dryer, it is very easy to cause a dust explosion accident, which will seriously threaten the personal safety of manual feeding personnel. In addition, the diffused reagent dust may also be inhaled by the operators, which will harm their health.

[0005] According to the patent application published on the Internet, the feeding device of a dryer for processing chemical reagents (authorization announcement number: CN212902542U) includes a "dryer body, base" etc., to realize the feeding operation.

[0006] Regarding the above description, the applicant believes the following issues exist:

[0007] The feeding device of this dryer for processing chemical reagents utilizes the dryer body and base to achieve feeding. During use, the device uses a filter screen for screening. However, the filter screen is fixed during screening, which causes chemical reagents to accumulate, affecting the screening efficiency. Furthermore, it is impossible to control the amount of reagent entering the filter screen, further affecting the screening and subsequent drying effects. Therefore, this device needs to be improved.

[0034] Example 1

[0035] Please see Figure 1-8 This utility model provides a technical solution: a feeding device for a dryer for chemical reagent processing, including a base 1, a dryer body 2 fixedly connected to the inner side of the base 1, a sealing door 3 rotatably connected to the front side of the dryer body 2, a feeding mechanism 4 provided on the top of the dryer body 2, a stirring mechanism 5 provided inside the dryer body 2, a heating tube 7 fixedly connected inside the dryer body 2, and an exhaust pipe 6 fixedly connected to the top of the rear side of the dryer body 2.

[0036] The feeding mechanism 4 includes a feeding component 41 and a lifting component 42. The feeding component 41 is located on the top of the dryer body 2, and the lifting component 42 is located around the feeding component 41.

A second servo motor 4192 is fixedly connected to the top of the rotating shaft 4193.

[0038] The dryer body 2 has a heating chamber and a wiring groove on the inside and left side, respectively. The heating tube 7 is fixedly connected to the heating chamber, and the wiring groove is circular and communicates with the heating chamber. The movable seat 413 is slidably connected to the support seat 411, and the rotating rod 416 is rotatably connected to the connecting pipe 415, so that the baffle 417 can be rotated through the rotating rod 416.

[0039] The baffle 417 is rotatably connected to the inside of the connecting pipe 415, the auger conveyor 419 is fixedly connected to the inside of the top of the movable seat 413, and screening holes are opened on the left and right sides, bottom and inside the sealing cover 4194 of the screening box 4191, all of which are circular, so as to facilitate the screening of solid chemical reagents through the screening box 4191.

[0040] Please see Figure 1-8 The present invention provides a technical solution: the lifting assembly 42 includes a fixed platform 421, the fixed platform 421 is fixedly connected to the top of the outer periphery of the dryer body 2, a second hydraulic cylinder 422 is fixedly connected to the top of the fixed platform 421, a support platform 423 is fixedly connected to the bottom of the second hydraulic cylinder 422, and the support platform 423 is slidably connected to the top of the dryer body 2 and the outer periphery of the rotating shaft 4193.

[0041] The top of the support platform 423 is fixedly connected to the bottom of the second servo motor 4192. Two sets of second hydraulic cylinders 422 are provided and symmetrically distributed on the front and rear sides of the top of the support platform 423. The fixed platform 421 is slidably connected to the periphery of the second servo motor 4192, so as to drive the screening box 4191 to be raised and lowered through the second hydraulic cylinders 422 and the support platform 423.

[0042] Example 2

[0043] Please see Figure 1-8 Furthermore, based on Embodiment 1, the stirring mechanism 5 further includes a third servo motor 51, which is fixedly connected to the bottom of the dryer body 2. A connecting shaft 52 is fixedly connected to the top of the third servo motor 51, and a stirring shaft 53 is fixedly connected to the periphery of the connecting shaft 52.

[0044] The connecting shaft 52 is rotatably connected inside the dryer body 2, so that the stirring shaft 53 can be rotated through the connecting shaft 52.

[0045] In actual operation, when this device is used and it is necessary to dry solid chemical reagents with a desiccant, the fixed chemical reagent is first put into the storage tank 414, so that the screening box 4191 is in the initial position at the top of the desiccant body. The first hydraulic cylinder 412 drives the moving seat 413 to slide inside the support seat 411, which drives the storage tank 414 and the auger conveyor 419 to move to the right, so that the right end of the auger conveyor 419 is slidably connected to the left side of the screening box 4191. At this time, the first servo motor 418 drives the rotating rod 416 to move around the fixed... The fixed connection baffle 417 rotates. By controlling the rotation angle of the baffle 417, the amount of chemical reagent entering the auger conveyor 419 can be controlled, avoiding the problems of excessive accumulation or insufficient feeding during traditional manual feeding, which affects the quality of drying and screening. After feeding, the chemical reagent will enter the screening box 4191 through the auger conveyor 419 under the action of the connecting pipe 415. After feeding is completed, the storage box 414 and the auger conveyor 419 can be moved to the left again under the action of the first hydraulic cylinder 412, so as to avoid affecting the lifting and moving of the support platform 423.

[0046] At this point, the screening box 4191 can be moved into the dryer body 2 by the action of the second hydraulic cylinder 422 and the support platform 423, and the top of the dryer body 2 can be sealed. At the same time, the heating tube 7 is heated by the external power supply, so that the heating tube 7 generates heat in the heating chamber. The second servo motor 4192 drives the rotating shaft 4193 and the screening box 4191 to rotate, so that the chemical reagents can be screened. The screened chemical reagents will enter the dryer body 2 through the screening holes to ensure their quality. The screened chemical reagents can then be dried under the heat generated by the heating tube 7.

[0047] During the drying process, the connecting shaft 52 and the stirring shaft 53 are driven to rotate by the third servo motor 51, which can further prevent the reagent from accumulating and allow the solid reagent to fully contact the heat generated by the heating tube 7, thereby improving the drying efficiency and uniformity. The water vapor generated during the drying process can be discharged in time through the exhaust pipe 6 at the top rear of the dryer body 2, preventing moisture from accumulating inside the machine and affecting the drying efficiency.

[0048] When it is necessary to clean the impurities after screening, simply move the support platform 423 and the screening box 4191 away from the top of the dryer body 2 under the action of the second hydraulic cylinder 422, place the collection device at the bottom of the screening box 4191, and take out the sealing cover 4194. The operation is convenient. Open the sealing door 3 to collect the dried chemical reagents.

[0049] In use, all the first hydraulic cylinder 412, the second hydraulic cylinder 422, the first servo motor 418, the second servo motor 4192, the third servo motor 51, the auger conveyor 419, and the heating tube 7 need to be connected to the same PLC controller near the dryer body 2 to ensure coordinated and automated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method, so it will not be described in detail in this case.
