DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 9 The present invention provides a technical solution: a chemical drying equipment, comprising: a drying cylinder 1 with two layers of partition support plates 17 fixedly connected inside, and electric heating plates are fixedly connected to the bottom of the partition support plates 17 at equal intervals; a filter assembly is placed on the top of the drying cylinder 1, and the filter assembly includes a funnel filter 12 rotatably placed on the top of the drying cylinder 1, and a grinding column 31 for extruding and grinding with the inner wall of the funnel filter 12 is rotatably provided at the bottom of the funnel filter 12; a transmission pipe 29 is rotatably placed inside the drying cylinder 1, the transmission pipe 29 passes through the bottom of the funnel filter 12 and is rotatably connected to the funnel filter 12, and the outer side of the transmission pipe 29 is provided with a filter for blowing and drying An air outlet pipe 20 for drying and a cleaning brush 22 for cleaning the dried material, a driving part is provided on the top of the cleaning brush 22, the air outlet pipe 20 is a hollow structure and is connected to the transmission pipe 29, and air outlet nozzles are equidistantly provided at the bottom of the air outlet pipe 20; the conveying pipe 2 is fixedly connected to the outside of the drying cylinder 1, the discharge port of the conveying pipe 2 extends into the funnel filter 12, the middle part of the conveying pipe 2 rotates a spiral blade 6, the spiral blade 6 and the conveying pipe 2 form a screw conveyor, the middle part of the spiral blade 6 is fixedly connected to the transmission pipe 3, the top of the transmission pipe 3 is connected to the transmission pipe 29 through the connecting pipe 4, and the bottom of the transmission pipe 3 is connected to the heat source through a rotating joint.

[0032] It should be noted that the present invention is provided with a controller and a corresponding operation panel, the bottom of the transmission pipe 3 is connected to the hot air, the hot air enters the transmission pipe 2 9 through the transmission pipe 1 3 and the connecting pipe 4, and then the transmission pipe 2 9 is blown out through the outlet pipe 20. During this process, the motor 13 drives the transmission pipe 1 3 and the transmission pipe 2 9 to rotate through the transmission, and the transmission pipe 1 3 reaches the material through the spiral blade 6 and is transported upward to the funnel filter 12. During this period, the heat of the hot air is transmitted to the spiral blade 6 through the transmission pipe 3, so that the spiral blade 6 is in the process of conveying the material. During drying, when the material enters the funnel filter 12, the funnel filter 12 rotates under the action of the transmission, and the material is screened by the funnel filter 12, so that when the logistics passes through the surface of the funnel filter 12, large particles fall into the inside of the funnel filter 12, and small particles penetrate the funnel filter 12 and fall into the top of the partition support plate 17 below. The particles that fall into the funnel filter 12 are squeezed and crushed by the contact and extrusion of the grinding column 31 and the inner wall of the funnel filter 12, so that the particles pass through the funnel filter 12 after being crushed and enter the bottom for drying.

[0033] like Figure 1 , 4 As shown in , 6, the top of the drying cylinder 1 is fixedly connected with a top cover 32, one side of the top cover 32 is rotatably connected with a transmission gear 10, the outer side of the transmission gear 10 is meshedly connected with a transmission ring gear 11, the transmission ring gear 11 is fixedly sleeved on the outer side of the funnel filter 12, the central axis of the transmission gear 10 is transmission-connected with a transmission tube 29 through a transmission belt assembly 230, the top of the top cover 32 is fixedly connected with a bracket 33, the transmission tube 29 is rotatably connected to the middle part of the bracket 33, one side of the bracket 33 is fixedly connected with a motor 13, the output end of the motor 13 is fixedly connected with a driving gear 14, the outer side of the driving gear 14 is meshedly connected with a transmission gear 2 15, and the transmission gear 2 15 is fixedly sleeved on the outer side of the transmission tube 29.

[0034] It should be noted that when the present invention is transmitted, the motor 13 drives the driving gear 14 to rotate, the driving gear 14 drives the transmission tube 29 to rotate through the transmission gear 2 15, the transmission tube 29 drives the transmission tube 3 to rotate through the belt and pulley of the transmission belt assembly 18, and at the same time, the transmission tube 29 drives the central axis of the middle part of the transmission gear 10 to rotate through the belt and pulley of the transmission belt assembly 2 30, the transmission gear 10 drives the transmission ring gear 11 to rotate, the transmission ring gear 11 reaches the funnel filter 12 to rotate, so that the funnel filter 12 is replaced at the position corresponding to the discharge of the conveying pipe 2 to prevent materials from piling up in the same place.

[0035] like Figure 1 , 3As shown in , 7, the grinding column 31 is fixedly connected to the transmission tube 29, and the transmission tube 29 is located at a position deviated from the center of the grinding column 31. The transmission tube 13 and the transmission tube 29 are connected through a transmission belt assembly 18. The outer side of the transmission tube 13 is equidistantly provided with hollow tubes 7 connected with multiple transmission tubes 13, which are used to heat the material transported by the conveying tube 2.

[0036] It should be noted that, under the transmission action of the transmission belt assembly 18, the transmission tube 13 and the transmission tube 29 rotate simultaneously. During the rotation of the transmission tube 13, hot air is transported upward from the bottom. Since the hollow tube 7 is connected to the transmission tube 13, heat is filled between the transmission tube 13 and the hollow tube 7, thereby increasing the contact area between the material and the heat. A vent is provided at the top of the conveying tube for discharging moisture, thereby improving the drying efficiency. The transmission tube 29 drives the grinding column 31 to rotate in the funnel filter 12. Since the grinding column 31 and the transmission tube 29 are eccentrically arranged, under the effect of the transmission ratio, the rotation speeds of the grinding column 31 and the funnel filter 12 are not the same, so that the end of the grinding column 31 deviating from the center of the circle and the inner wall of the funnel filter 12 can be squeezed and crushed. The transmission tube 29 transfers heat to the grinding column 31, and the grinding column 31 can be dried during grinding.

[0037] like Figure 1 , 3 As shown in , 4 and 7, a heating box 5 is fixedly connected to one side of the bracket 33 via a connecting plate, a heating wire 16 is fixedly connected to the interior of the heating box 5, the bottom of the heating box 5 is connected to the transmission pipe 29 via a rotating joint, and the top of the heating box 5 is connected to the connecting pipe 4.

[0038] It should be noted that when the hot air of the present invention is dried inside the conveying pipe, its temperature will be lower due to the effect of heat exchange, and the hot air enters the heating box 5 through the connecting pipe 4, is heated by the electric heating wire 16 in the heating box 5, and the heated hot air enters the transmission pipe 2 9 through the rotary joint, and is sprayed onto the material through the outlet pipe 20 for drying.

[0039] like Figure 3 , 4 As shown in FIG. 8 , a plurality of leakage grooves 18 are equidistantly provided in the middle of the partition support plate 17. A shifting plate 19 is fixedly connected to the outer side of the transmission pipe 29 and located above the partition support plate 17. The shifting plate 19, the cleaning brush 22 and the air outlet pipe 20 are arranged at the same angle in a clockwise direction.

[0040] It should be noted that the material of the present invention enters the top of the partition support plate 17 through the funnel filter 12, and the transmission pipe 29 drives the shifting plate 19, the cleaning brush 22 and the air outlet pipe 20 to rotate. The shifting plate 19 is set at an angle. The shifting plate 19 levels the material to prevent material accumulation and uneven drying. After the cleaning brush 22 is flattened, the air outlet pipe 20 blows out heat and slides through the top of the logistics to dry the material. After drying for a certain period of time, under the action of the timer, the moving logistics under the cleaning brush 22 is cleaned so that it passes through the leakage trough 18 and falls into the top of the partition support plate 17 below.

[0041] like Fig. 9 As shown, the driving part includes a support rod 21 fixedly connected to the outside of the transmission tube 29, the middle part of the support rod 21 is slidably connected to the limit rod 26, the cleaning brush 22 is fixedly connected to the bottom of the limit rod 26, the top of the limit rod 26 is fixedly connected to the connecting rod 23, and a spring 25 is sleeved on the outside of the limit rod 26 and located between the support rod 21 and the connecting rod 23. Electromagnets 24 are correspondingly arranged at the bottom of the connecting rod 23 and the top of the support rod 21. The magnetic poles of the two electromagnets 24 are opposite when energized, and the suction force of the electromagnet 24 when energized is greater than the elastic force of the spring 25.

[0042] It should be noted that when the present invention cleans the material, under the action of the controller, the two electromagnets 24 are energized at the same time. Under the action of suction, the connecting rod 23 drives the heating wire 16 to move downward and compresses the spring 25, the limiting rod 26 drives the cleaning brush 22 to move downward, and the transmission tube 29 drives the support rod 21 to rotate, so that the cleaning brush 22 cleans the surface of the partition support plate 17, and the material is swept into the shifting plate 19 by the cleaning brush 22. When the electromagnet 24 is de-energized, the spring 25 drives the connecting rod 23 to reset, and the connecting rod 23 drives the cleaning brush 22 to reset through the limiting rod 26.

[0043] like Figure 4 As shown, a receiving hopper is fixedly connected to the bottom of the drying cylinder 1, a spiral conveying tube 27 is fixedly connected to the bottom of the receiving hopper, a spiral conveying rod is rotatably connected to the inside of the spiral conveying tube 27, a bevel gear 29 is fixedly connected to the end of the spiral conveying rod, a bevel gear 29 is meshingly connected to the outer side of the bevel gear 29, and the bevel gear 1 28 is fixedly connected to the transmission tube 1 3.

[0044] It should be noted that after the material of the present invention is dried on the top of the partition support plate 17, it enters the receiving funnel through the leakage trough 18 and then enters the spiral conveying pipe 27. When the transmission pipe 13 conveys the material, the transmission pipe 13 drives the bevel gear 2 29 to rotate through the bevel gear 1 28, and the bevel gear 2 29 drives the spiral blades inside the spiral conveying pipe 27 to rotate, thereby pushing out the dried material.
