DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] See also Figure 1-Figure 6 As shown, an auxiliary rotary potassium citrate crystal uniform drying device includes a drying box 100, wherein the drying box 100 is respectively provided with a feed inlet 101 and a discharge outlet 102, wherein the inner wall of the drying box 100 is coaxially provided with an inner filter frame 105, wherein the side wall of the inner filter frame 105 is connected with a fan 106, wherein the surface of the drying box 100 is provided with multiple groups of heating wires 103 at equal intervals along the horizontal direction of the drying box 100, wherein the outer jacket of the heating wires 103 is provided with a heat-insulating shell 104, wherein the heat-insulating shell 104 ... The warm shell 104 is fixed on the drying box 100. The inner wall of the drying box 100 is provided with a stirring mechanism 200 for stirring the potassium citrate crystals in a horizontal direction so that they are heated evenly. The inner filter frame 105 is provided with a gas outlet mechanism 300 for evenly outleting the gas blown out by the fan 106 from the inner filter frame 105. The drying box 100 is provided with a cleaning mechanism 400 coaxially with the drying box 100 and rotating along the circumferential direction of the drying box 100 for cleaning the potassium citrate crystals attached to the inner wall of the drying box 100.

[0036] It should be noted that the inner filter frame 105 is provided with a plurality of one-way holes at uniform intervals. When in use, potassium citrate crystals are added into the drying box 100 through the feed port 101. The potassium citrate crystals are located between the drying box 100 and the inner filter frame 105. Under the action of the heating wire 103, the temperature in the drying box 100 increases. At the same time, the fan 106 blows out gas, which passes through the one-way holes on the inner filter frame 105 to form hot air to dry the crystals. The one-way holes are set so that the gas can be blown from the inner filter frame 105. However, the potassium citrate crystals will not enter the inner filter frame 105. Starting the stirring mechanism 200 can make the crystals evenly heated in the horizontal direction, and the cleaning mechanism 400 is responsible for cleaning the crystals attached to the inner wall of the drying box 100. The gas outlet mechanism 300 ensures that the gas blown out by the fan 106 can evenly pass through the one-way holes on the inner filter frame 105, providing a uniform drying environment for the potassium citrate crystals. The dried potassium citrate crystals are discharged from the drying box 100 from the discharge port 102 for collection.

[0037] See also Figure 2-Figure 3 As shown, the stirring mechanism 200 includes a stirring shaft 202 and a spiral blade 204. The stirring shaft 202 is rotatably arranged on the inner wall of the drying box 100 through a bearing. A driving member for driving the stirring shaft 202 to rotate is fixed on the drying box 100, and the spiral blade 204 is fixed on the stirring shaft 202.

[0038] When in use, the stirring shaft 202 rotates, driving the spiral blades 204 to rotate accordingly, thereby stirring the potassium citrate crystals in the drying box 100, making them evenly heated, thereby improving the drying efficiency and product quality.

[0039] See also Figure 2 As shown, two stirring shafts 202 are symmetrically arranged along the central axis of the inner filter frame 105 , and spiral blades 204 are arranged on the two stirring shafts 202 .

[0040] The two stirring shafts 202 are symmetrically arranged on both sides of the central axis of the inner filter frame 105, and the spiral blades 204 on each of them work together to stir the crystals in the drying box 100, so that the potassium citrate crystals are dried more evenly.

[0041] See also Figure 2-Figure 3 As shown, the driving member includes a motor 201 and a transmission belt 203 . A driving wheel is fixedly sleeved on the output end of the motor 201 . A driven wheel is sleeved on the stirring shaft 202 . The driving wheel and the driven wheel are connected through the transmission belt 203 .

[0042] When stirring, the motor 201 is started, and the driving wheel at the output end of the motor 201 drives the driven wheel on the stirring shaft 202 to rotate through the spiral blade 204, thereby driving the stirring shaft 202 to rotate.

[0043] See also Figure 3-Figure 6 As shown, the gas derivation mechanism 300 includes a threaded spindle 301, a limiting rod 302 and a piston 303. The threaded spindle 301 is coaxially arranged with the inner filter frame 105. One end of the threaded spindle 301 rotates through the drying box 100 and is transmission-connected with the output end of the motor 201. The other end of the threaded spindle 301 is rotationally connected with the side wall of the drying box 100. The piston 303 is threadedly sleeved on the threaded spindle 301. A through hole is opened on the piston 303 for the limiting rod 302 to slide through. The limiting rod 302 is fixedly arranged on the inner wall of the inner filter frame 105.

[0044] The motor 201 drives the threaded spindle 301 to rotate, and is constrained by the limit rod 302, so that the piston 303 reciprocates on the threaded spindle 301, ensuring that the gas blown by the fan 106 can evenly pass through the one-way hole of the inner filter frame 105, providing a uniform drying environment for potassium citrate crystals.

[0045] See also Figure 5-Figure 6 As shown, the cleaning mechanism 400 includes a fixed ring 401, a rotating frame 402 and a scraper 403. The fixed ring 401 is fixedly sleeved on one end of the threaded main shaft 301 that is rotatably connected to the drying box 100. The rotating frame 402 is symmetrically arranged on the fixed ring 401 along the central axis of the fixed ring 401. The scraper 403 is fixedly arranged on the side of the rotating frame 402 and contacts the inner wall of the drying box 100.

[0046] When the threaded spindle 301 rotates, the fixed ring 401 drives the rotating frame 402 to rotate accordingly, so that the scraper 403 rotates to clean the crystals attached to the inner wall of the drying box, effectively avoiding the accumulation of potassium citrate crystals on the inner wall of the drying box 100, and ensuring the normal operation and drying effect of the device.

[0047] See also Figure 5-Figure 6 As shown, the scraper 403 is in a trapezoidal shape with one end larger than the other end. The end of the scraper 403 connected to the rotating frame 402 has a larger area, and the end in contact with the drying box 100 has a smaller area.

[0048] The trapezoidal scraper 403 can more effectively clean the crystals on the inner wall of the drying box 100 .

[0049] See also Figure 5-Figure 6 As shown, a plurality of stirring blades 404 are fixedly provided on one side of the rotating frame 402 close to the spiral blade 204 , and the stirring blades 404 are spaced apart from the spiral blade 204 .

[0050] When the rotating frame 402 rotates, the stirring blade 404 is driven to rotate. The stirring blade 404 is spaced apart from the spiral blade 204 , so that the stirring blade 404 and the spiral blade 204 can work together to further enhance the stirring effect.

[0051] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
