Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of drying machines, in particular to a low-temperature drying equipment for silicon mud materials. BACKGROUND

[0002] Silicon mud is a kind of waste material generated in the process of industrial production, mainly from the silicon wafer cutting process of the solar photovoltaic industry. With the popularization of diamond wire cutting technology, a large amount of cutting silicon powder will be generated in the process of silicon wafer cutting. These silicon powders are mixed with cooling liquid to form waste silicon mud. In order to facilitate the subsequent recycling and reuse of silicon mud, it is necessary to dry the silicon mud.

[0003] In the prior art, when drying the silicon mud, a drum dryer is often used to dry the silicon mud. The main working principle is to pass the silicon mud to be dried into a rotatable drum, and then pass high-temperature gas into the drum or directly heat the drum wall to indirectly heat the silicon mud in the drum, so as to evaporate and discharge the water in the silicon mud, thereby realizing the drying of the silicon mud.

[0004] In the above-mentioned technology, in order to ensure the drying efficiency, a higher drying temperature is required. However, a too high drying temperature will cause oxidation of the silicon mud during the drying process, thereby affecting the subsequent recycling operation.

[0023] As Figure 1 and Figure 3As shown, the two ends of the drum 2 and close to the bottom position are slidably connected with the arc-shaped plates 10; the bottom surfaces of the two arc-shaped plates 10 are rotatably connected with the support plates 11; the support plate 11 close to the end cover one 3 is rotatably connected with the support seat 1 and the hydraulic rod 12; the support plate 11 close to the end cover two 8 is fixedly connected with the support seat 1; during operation, when the silicon mud in the drum 2 needs to be taken out, the user needs to remove the end cover two 8 at the end of the drum 2, so that one end of the drum 2 is in an open state, at this time, the hydraulic rod 12 at the support seat 1 is started, and the drum 2 close to the end cover one 3 is lifted up through the support plate 11, so that one end of the drum 2 close to the end cover two 8 is the lower end, and the material in the drum 2 will also move to the end of the drum 2 close to the end cover two 8, at this time, the servo motor drives the drum 2 to rotate, so that the spiral stirring plate 6 also rotates with the drum 2, thereby achieving the transportation effect of the material in the drum 2, so that the material in the drum 2 can be discharged from the drum 2 more quickly, thereby improving the unloading efficiency of the embodiment.

[0024] As shown in Figure 1 , Figure 5 and Figure 7 , the two sides of the support seat 1 are rotatably connected with the rotating rods 13; the surfaces of the rotating rods 13 are fixedly connected with the cover shells 14, and the side of the cover shell 14 close to the drum 2 is fixedly connected with the infrared reflecting material; one end of the support seat 1 close to the end cover one 3 is fixedly connected with the driving rod 15; the driving rod 15 is driven by the servo motor two, and the driving rod 15 is connected with the two rotating rods 13 through the gear set; during operation, when the heating wire 7 is about to heat the drum 2, the servo motor two needs to drive the driving rod 15 to rotate, and then the driving rod 15 drives the two rotating rods 13 to synchronously rotate towards each other through the gear set, thereby enabling the cover shells 14 on the surfaces of the two rotating rods 13 to be buckled together, thereby achieving the shading effect of the drum 2, and since the infrared reflecting material is fixedly connected in the cover shell 14, the heat preservation effect of the drum 2 can be achieved, thereby reducing the waste of heat and saving electricity, thereby reducing the operation cost of the embodiment.

[0025] As shown in Figure 1As shown, the locking assembly comprises a pair of driving plates 16; the driving plates 16 are slidingly connected on both sides of the support base 1, and the driving plates 16 are driven by the servo motor three; one end of the driving plate 16 close to the end cover two 8 is fixedly connected with a connecting frame 17; the end cover two 8 is rotatably connected on the side of the connecting frame 17 close to the roller 2; when the user needs to tightly buckle the end cover two 8 on the surface of the roller 2, the user needs to drive the driving plate 16 to slide along the support base 1 by the servo motor three, and since the end cover two 8 is fixedly connected on the surface of the driving plate 16 through the connecting frame 17, the end cover two 8 will also move together with the driving plate 16, so that the driving plate 16 can not only tightly buckle the end cover two 8 on the end surface of the roller 2, but also can move the end cover two 8 away from the end surface of the roller 2, so that the user can move the end cover two 8 away when discharging is needed, thereby reducing the operation difficulty of the user.

[0026] As shown in Figure 2 and Figure 6 As shown, the side of the end cover two 8 away from the roller 2 is slidingly connected with a plurality of uniformly arranged sliding plates 18; one end of the sliding plate 18 away from the end cover two 8 is fixedly connected with a connecting rod 19; the connecting rod 19 is fixedly connected with a pressing plate 20 away from the sliding plate 18; the thickness of the pressing plate 20 close to the connecting rod 19 is greater than the thickness of the pressing plate 20 away from the connecting rod 19; when the connecting frame 17 buckles the end cover two 8 on the surface of the roller 2, the user needs to slide the sliding plate 18 on the surface of the end cover two 8, so that the sliding plate 18 moves towards the center of the end cover two 8, at this time the sliding plate 18 will also drive the pressing plate 20 to move synchronously through the connecting rod 19, so that the pressing plate 20 also moves towards the center of the end cover, so as to realize the clamping of the sliding plate 18 and the pressing plate 20 on the end cover and the end part of the roller 2, so that the edges of the two can also be subjected to corresponding pressure, thereby improving the sealing between the roller 2 and the end cover two 8, and improving the friction between the end cover two 8 and the roller 2, so that the end cover two 8 can rotate with the roller 2, and the probability of slipping between the two is reduced.

[0027] As shown in Figure 1 and Figure 6As shown, a pair of guide rails 21 are fixedly connected to the side of the support base 1 near the end cover 8; the two guide rails 21 are fixed together at their close ends, and the close ends of the two guide rails 21 are higher than their far ends; a sleeve 22 is rotatably connected to the surface of the connecting rod 19; during operation, when the user slides the slide plate 18 toward the center of the end cover 8, the user needs to drive the roller 2 to rotate through the drive motor, and the rotating roller 2 will drive the end cover 8 to rotate together. During the rotation, the sleeve 22 on the surface of the connecting rod 19 will contact the guide rails 21 and squeeze the sleeve 22, thereby pressing the pressure plates 20 at both ends of the connecting rod 19 and the sleeve 22 and the slide plate 18 toward the center of the end cover 8, thereby achieving further fixation between the end cover 8 and the roller 2, and eliminating the need for the user to manually slide the slide plates 18 one by one, thus reducing the difficulty of operation and improving the usability of the embodiment of the present invention.

[0028] like Figure 6 As shown, a connecting frame 23 is fixedly connected to the surface of the end cap 2 8 at the corresponding position of the slide plate 18, and the connecting frame 23 is located near the edge of the end cap 2 8; a magnet block 24 is fixedly connected to the end of the slide plate 18 away from the connecting rod 19; the connecting frame 23 is made of magnetizable metal; during operation, when it is necessary to release the lock between the end cap 2 8 and the roller 2, the user needs to slide the slide plate 18 so that the surface magnet block moves toward the connecting frame 23 and finally adheres to and is attracted to the surface of the connecting frame 23, thereby fixing the slide plate 18. At this time, when the user moves the end cap 2 8, its surface pressure plate 20 will not interfere with the roller 2, so that the end cap 2 8 can freely fasten toward or away from the roller 2.

[0029] like Figure 1 , Figure 8 and 9 As shown, a rotating arm 25 is rotatably connected to one side of the support base 1; a hopper 26 is fixedly connected to the end of the rotating arm 25 away from the support base 1; a guide tube 27 is fixedly connected to the bottom end of the hopper 26; the guide tube 27 is L-shaped; an extension tube 28 is slidably connected to the end of the guide tube 27 away from the hopper 26; an annular plate 29 is fixedly connected to the surface of the guide tube 27; the annular plate 29 is made of magnet, and the extension tube 28 is made of magnetizable metal; during operation, when feeding is required, the user removes the end cap 28 from the roller 2... After the end face is removed, the user needs to rotate the arm 25 to rotate the hopper 26 at the end of the rotating arm 25 to the end of the drum 2. Then, the extension tube 28 is slid to disengage its end from the suction of the annular plate 29 and finally insert it into the drum 2. At this time, the user can convey the material into the hopper 26 through the conveyor belt. Under the guidance of the hopper 26, the guide tube 27 and the extension tube 28, the material is finally sent into the drum 2. This facilitates the user's feeding operation, makes it easy for the material to be sent into the drum 2 and reduces material waste.

[0030] As shown in Figure 1 And Figure 8 As shown in the driving plate 16 close to the rotating arm 25, its far from the end cap two 8 one end of the solid tooth plate 30; the support seat 1 surface close to the rotating arm 25 one side rotationally connected with transmission rod 31; the surface of the transmission rod 31 is fixed with main gear 32, and the main gear 32 can be engaged with the tooth plate 30; the transmission rod 31 and rotating arm 25 between the bevel gear set transmission; work, when the driving plate 16 will drive plate 30 and main gear 32 from the end cap two 8 from the drum 2 degrees away, in turn, drive plate 16 will drive plate 30 and main gear 32 meshing, in turn, drive transmission rod 31 rotation, so that the rotating transmission rod 31 will be driven by the bevel gear set rotating arm 25, so that it rotates to the designated location, thus without the need for manual rotation, thereby further reducing the difficulty of operation of the user.

[0031] As shown in Figure 4 The drum 2 inner wall close to both ends of the position are fixed with guide plate 33; the guide plate 33 is annular, and the cross section of the guide plate 33 is a right triangle; work, when the material is sent into the drum 2 inside, the guide plate 33 in the drum 2 inside will play a guiding role to the material, so that the material is concentrated in the barrel middle part, in turn, so that the material can be fully stirred by the stirring plate 6 and the electric heating wire 7.

[0032] Work, in order to reduce the silica clay material in the drying process of oxidation, can use the present application embodiment, first the user needs to open the end cap two 8 of the drum 2 end, so that the silica clay material to be dried can be sent into the drum 2 inside, then the end cap two 8 is buckled again to the end of the drum 2, and the locking assembly is tightly buckled on the end surface of the drum 2, and the sealing ring 9 of the end cap two 8 and the end surface of the drum 2 completes the sealing of the two, and then the external vacuum pump starts, and the drum 2 is pumped to vacuum through the suction pipe 4 and the branch pipe 5, and then the electric heating wire 7 starts, and the drum 2 is heated to 50-80 DEG C, and then the servo motor one starts, and drives the drum 2 and its internal stirring plate 6 to rotate, so as to realize the stirring of the silica clay material, so that the silica clay material can be fully contacted with the inner wall of the drum 2, and then the silica clay material can be fully heated, and the water vapor evaporated is pumped out of the drum 2 by the suction pipe 4 and the branch pipe 5, so that the inside of the drum 2 is always in a low pressure environment, so that the gas in the drum 2 is continuously pumped out by the suction pipe 4 and the branch pipe 5, so that the inside of the drum 2 is in a low pressure state, thereby reducing the boiling point of the liquid in the silica clay material, so that the liquid in the silica clay material can be rapidly evaporated at a lower temperature, and the gas in the drum 2 is pumped out, which can also play a protective role for the silica clay material, avoiding the oxidation reaction of the silica clay material with oxygen in the air, so as to ensure the quality of the finally dried silica clay.

[0033] When the user needs to take out the silicon mud dried in the drum 2, the user needs to remove the end cover two 8 at the end of the drum 2 first, so that one end of the drum 2 is open, at this time the hydraulic rod 12 at the support seat 1 is started, and the drum 2 is lifted by the support plate 11 close to the end cover one 3, so that the end of the drum 2 close to the end cover two 8 is the lower end, and the material in the drum 2 will also move to the end of the drum 2 close to the end cover two 8, at this time the servo motor drives the drum 2 to rotate, so that the spiral stirring plate 6 also rotates with the drum 2, thereby achieving the transportation effect of the material in the drum 2, thereby improving the discharging efficiency of the embodiment of the application.

[0034] When the electric heating wire 7 is about to heat the drum 2, the servo motor two needs to drive the driving rod 15 to rotate, and then the driving rod 15 drives the two rotating rods 13 to rotate synchronously and oppositely through the gear set, thereby enabling the two cover shells 14 on the surfaces of the two rotating rods 13 to be buckled together, thereby achieving the shading effect of the drum 2, and since the cover shell 14 has the infrared emitting material fixed therein, the cover shell 14 can achieve the heat preservation effect of the drum 2, thereby reducing the waste of heat and saving electricity, thereby reducing the operation cost of the embodiment of the application, and when the drum 2 needs to be discharged, the driving rod 15 drives the two cover shells 14 to move away from each other through the rotating rod 13, thereby not hindering the rising of the drum 2.

[0035] When the user needs to tightly buckle the end cover two 8 on the surface of the drum 2, the user needs to drive the driving plate 16 to slide along the support seat 1 through the servo motor three, and since the end cover two 8 is fixed on the surface of the driving plate 16 through the connecting frame 17, the end cover two 8 also moves together with the driving plate 16, so that the driving plate 16 can not only tightly buckle the end cover two 8 on the end surface of the drum 2, but also can move the end cover two 8 away from the end surface of the drum 2, thereby reducing the operation difficulty of the user.

[0036] When the connecting frame 17 buckles the end cover two 8 on the surface of the drum 2, the user needs to slide the sliding plate 18 on the surface of the end cover two 8, so that the sliding plate 18 moves towards the center of the end cover two 8, at this time the sliding plate 18 also drives the pressing plate 20 to move synchronously through the connecting rod 19, so that the pressing plate 20 also moves towards the center of the end cover, thereby achieving the clamping of the sliding plate 18 and the pressing plate 20 on the end cover and the end of the drum 2, so that the edges of the two can also be subjected to corresponding pressure, thereby improving the sealing between the drum 2 and the end cover two 8, and improving the friction between the end cover two 8 and the drum 2, so that the end cover two 8 can rotate with the drum 2, thereby reducing the probability of slipping between the two.

[0037] When the user slides the sliding plate 18 towards the center of the end cover two 8, the user needs to drive the motor one to drive the roller 2 to rotate, and the rotating roller 2 drives the end cover two 8 to rotate together. In the process of rotation, the sleeve 22 on the surface of the connecting rod 19 will be in contact with the guide rail 21 and be extruded, thereby pressing the pressing plate 20 and the sliding plate 18 at both ends of the connecting rod 19 and the sleeve 22 towards the center of the end cover two 8, so as to further fix the end cover two 8 and the roller 2, and the user does not need to manually slide the sliding plate 18 one by one, thereby reducing the operation difficulty and improving the ease of use of the embodiment of the application.

[0038] When it is necessary to release the locking between the end cover two 8 and the roller 2, the user needs to slide the sliding plate 18, so that the surface magnet block moves towards the connecting frame 23 and finally adheres and is adsorbed on the surface of the connecting frame 23, so as to fix the sliding plate 18. At this time, when the user moves the end cover two 8, the surface pressing plate 20 will not interfere with the roller 2, so that the end cover two 8 can freely approach or move away from the roller 2.

[0039] When it is necessary to load, after the user removes the end cover two 8 from the end surface of the roller 2, the user also needs to rotate the arm 25, so as to rotate the hopper 26 at the end of the arm 25 to the end of the roller 2, and then slide the extension pipe 28, so that the end thereof is separated from the adsorption of the annular plate 29 and finally inserted into the inside of the roller 2. At this time, the user can transport the material into the hopper 26 through the material conveying belt, and finally into the inside of the roller 2 under the guidance of the hopper 26, the guide pipe 27 and the extension pipe 28, thereby facilitating the loading operation of the user, enabling the material to be easily sent into the inside of the roller 2, and reducing the waste of the material.

[0040] When the driving plate 16 removes the end cover two 8 from the roller 2, the driving plate 16 also drives the gear plate 30 to engage with the main gear 32, thereby driving the transmission rod 31 to rotate, so that the rotating transmission rod 31 drives the rotating arm 25 to rotate through the bevel gear set, so that it is rotated to the specified position, thereby not needing the user to manually rotate, thereby further reducing the operation difficulty of the user.

[0041] When the material is sent into the inside of the roller 2, the guide plate 33 in the inside of the roller 2 plays a guiding role on the material, so that the material is concentrated in the middle of the barrel, thereby enabling the material to be fully stirred by the stirring plate 6 and fully heated by the electric heating wire 7.

[0042] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application.
