Airflow dryer for potassium chloride production

Abstract

This utility model discloses an airflow dryer for potassium chloride production. The screening device includes a screening component installed inside the dryer body for back-and-forth movement. The screening component contains a vibrating component for removing accumulated potassium chloride. The recovery device includes a connecting component installed inside the dryer body. At the other end of the connecting component is a recovery component for separating the dried potassium chloride from the dryer body. Thus, a motor causes a cam to rotate within a groove, intermittently moving a sleeve plate up and down. Simultaneously, the elasticity of a spring on a round rod causes the screening screen to vibrate intermittently, preventing clogging of the filter holes on the screening screen. Finally, an exhaust fan draws the dried potassium chloride and hot air from the dryer body along the suction hood and connecting pipe to a cyclone separator, which separates the dried potassium chloride from the hot air.

Description

Technical Field

[0001] This utility model relates to the technical field of chemical production equipment, and in particular to an airflow dryer for potassium chloride production. Background Technology

[0002] Potassium chloride is an inorganic compound that looks like table salt, is odorless, and has a salty taste. It is often used as an additive in low-sodium salt and mineral water. Currently, most potassium chloride products require the use of a potassium chloride airflow dryer for drying during processing.

[0003] Existing airflow dryers use a suction fan to introduce hot air generated in the heating components into the fluidized bed to dry potassium chloride.

[0004] However, when using an airflow dryer to dry potassium chloride, the hydrated potassium chloride easily clumps together in the fluidized bed, which can clog the double-layer filter plates. As a result, the airflow dryer often needs to be shut down and the double-layer filter plates cleaned. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, this utility model proposes an airflow dryer for potassium chloride production. When potassium chloride needs to be dried using the dryer body, a suction fan can transport the hot airflow generated by the heating element along the connecting pipe to the dryer body for drying. Simultaneously, a motor drives the rotating shaft to rotate, causing the cam to rotate within the groove and intermittently move the sleeve plate up and down. Furthermore, the elasticity of the spring on the round rod causes the screening screen to vibrate intermittently, thus preventing clogging of the filter holes on the screening screen and increasing the flow of hot air within the dryer body. When the dried potassium chloride needs to be recovered, an exhaust fan can draw the dried potassium chloride and hot airflow from the dryer body along the suction hood and connecting pipe to a cyclone separator. The cyclone separator separates the dried potassium chloride from the hot air, facilitating the operator's recovery of the dried potassium chloride.

[0007] To achieve the above objectives, this utility model proposes an airflow dryer for potassium chloride production, comprising a dryer body, a drying device for supplying hot air into the dryer body at its right end, a screening device for screening potassium chloride within the dryer body, and a recovery device for separating the dried potassium chloride within the dryer body at its top. The drying device includes a connecting pipe at the right end of the dryer body, a heating component fixedly installed at the right end of the connecting pipe, and a suction fan for supplying air into the heating component at the right end of the heating component. The screening device includes a screening component that moves back and forth within the dryer body, and a vibration component for vibrating and removing accumulated potassium chloride within the screening component. The recovery device includes a connecting component within the dryer body, and a recovery component for separating the dried potassium chloride within the dryer body at its other end.

[0029] In one embodiment of this utility model, such as Figure 2 As shown, the top of the dryer body 100 is provided with a cover plate 101 for tightening the dryer body 100. A handle 102 is fixedly installed on the top of the cover plate 101. There are two handles 102, which are welded to the cover plate 101 symmetrically from left to right, so that the cover plate 101 can be lifted by using the two handles 102, thereby facilitating the replacement or maintenance of the parts inside the dryer body 100.

[0030] Furthermore, the cover plate 101 is provided with bolts 103 for fixing the cover plate 101 to the top of the dryer body 100, and the bolts 103 pass through the cover plate 101 and are threadedly connected to the top of the dryer body 100, so that the top of the dryer body 100 can be tightly covered by the cover plate 101; the dryer body 100 is provided with an installation groove 104 for clamping the screening component 310, and the bottom of the dryer body 100 is provided with a fixing platform 105 for supporting the dryer body 100.

[0031] In one embodiment of this utility model, such as Figures 3-6As shown, the screening assembly 310 includes a second mounting block 315 that is fitted into the mounting groove 104.

A second groove 316 is provided in the second mounting block 315, and a screening screen plate 311 for screening potassium chloride in the dryer body 100 is provided on the front side of the second mounting block 315.

[0032] Furthermore, a mounting block 312 for supporting the screening screen plate 311 is provided on the front side of the screening screen plate 311. A groove 313 is provided in the mounting block 312. A handle 314 for driving the screening screen plate 311 to move back and forth is fixedly installed at the front end of the mounting block 312. Therefore, the screening screen plate 311 can be pulled out from the dryer body 100 through the handle 314, which makes it convenient to replace the screening screen plate 311.

Furthermore, spring 325 can be fitted onto round rod 324; round rod 326 for penetrating sleeve plate 317 is fixedly installed in groove 316; thus, when potassium chloride is dried using the dryer body 100, the wet potassium chloride can fall onto the screening screen plate 311; when the motor 321 drives the rotating shaft 322 to rotate, the cam 323 can rotate in groove 313 and intermittently move sleeve plate 318 up and down; at the same time, under the elastic action of spring 325 on round rod 324, the screening screen plate 311 can be intermittently vibrated; thereby, the filter holes on the screening screen plate 311 can be prevented from becoming blocked, thereby increasing the flow of hot air in the dryer body 100.

[0034] In one embodiment of this utility model, such as Figure 7As shown, the recovery assembly 410 includes a cyclone separator 411 fixedly installed at the front end of the connecting assembly 420. The top of the cyclone separator 411 is provided with an exhaust fan 412 for absorbing the dried potassium chloride in the dryer body 100 along the connecting assembly 420 into the cyclone separator 411.

[0035] Furthermore, the connecting assembly 420 includes an air intake hood 423 disposed within the dryer body 100.

A support plate 422 for supporting the connecting pipe 421 is fixedly installed at the top end of the cover plate 101. Thus, when it is necessary to recover the dried potassium chloride, the dried potassium chloride and hot air flow in the dryer body 100 can be drawn along the air intake hood 423 and the connecting pipe 421 to the cyclone separator 411 by the exhaust fan 412. The cyclone separator 411 will separate the dried potassium chloride and hot air, making it convenient for the operator to recover the dried potassium chloride.

[0036] In summary, this utility model provides an airflow dryer for potassium chloride production. When potassium chloride needs to be dried using the dryer body 100, the hot airflow generated by the heating component 220 is transported along the connecting pipe 230 to the dryer body 100 by the suction fan 210 to dry the potassium chloride. Simultaneously, the motor 321 drives the rotating shaft 322 to rotate, causing the cam 323 to rotate within the groove 313 and intermittently move the sleeve 318 up and down. Meanwhile, the elasticity of the spring 325 on the round rod 324... Under the action, the screening screen plate 311 can be intermittently vibrated; thus, the filter holes on the screening screen plate 311 can be prevented from becoming blocked, thereby increasing the flow of hot air in the dryer body 100; when it is necessary to recover the dried potassium chloride, the dried potassium chloride and hot air in the dryer body 100 can be drawn into the cyclone separator 411 by the exhaust fan 412 along the suction hood 423 and the connecting pipe 421; the cyclone separator 411 will separate the dried potassium chloride and hot air, making it convenient for the operator to recover the dried potassium chloride.
