DETAILED DESCRIPTION

[0021] See also Figure 1-7 The utility model provides the following technical solutions: a bentonite screening device, comprising a box body 1, a telescopic rod 2, a fan 4 and a vibration motor 6, and also comprising a drying bin 3 and a screening bin 5. The box body 1 is staggered with symmetrical screening bins 5, and the screening bin 5 is provided with a plurality of inclined screens 51, and the sizes of the screens 51 are different. The side wall of the box body 1 is provided with a discharge port 2 13 at the lowest end of the screens 51 and the screening bin 5, and the side wall of the box body 1 is provided with a plurality of discharge pipes 12. The discharge port 2 13 matched with the screens 51 of the same size is connected with the same discharge pipe 12. The bottom of the box body 1 is provided with a discharge port 11 and a vibration motor 6. The top of the box body 1 is provided with a symmetrical drying bin 3, and the interior of the drying bin 3 is provided with an electric stirring rod 31. The interior of the blades of the electric stirring rod 31 is provided with a heating plate 34, and the bottom opening of the drying bin 3 is provided with an electric sealing plate 32.

[0022] The bentonite can be screened through the screening bin 5 and the screen 51, the vibration motor 6 can vibrate the box 1, and the vibrating box 1 will vibrate with the screening bin 5, so that the screen 51 can screen the bentonite. By setting a plurality of screens 51 of different sizes on the screening bin 5, the device can screen the bentonite into different sizes. The screen 51 is an inclined surface, and the bentonite will move along the screen 51 during the filtration process, so as to avoid the bentonite accumulation on the surface of the screen 51, which will affect the filtering effect of the device. The plurality of screening bins 5 are symmetrically staggered inside the box 1, and the screening bins 5 are installed in the box 1. After the bentonite is placed on the box body 1, a bent material conveying channel is formed inside the box body 1, which increases the distance that the bentonite moves inside the box body 1 and improves the filtering effect of the device. The bentonite filtered by the screen 51 will enter the discharge pipe 12 through the discharge port 13, and then the filtered bentonite is discharged from the device through the discharge pipe 12, thereby realizing the collection of bentonite of different sizes. The bentonite of too large size will fall to the bottom of the box body 1, and the bentonite that falls to the bottom of the box body 1 will be discharged from the device through the discharge port 11. The shapes of the discharge port 11 and the discharge pipe 12 are all inclined surfaces, which ensures that the filtered bentonite is discharged in the discharge. The smoothness of the internal movement of the first port 11 and the discharge pipe 12, the position of the second discharge port 13 ensures that the bentonite filtered by the screen 51 can be completely discharged from the interior of the box 1, and the working effect of the device is ensured. The drying chamber 3 can heat and dehumidify the bentonite, the electric stirring rod 31 can stir the bentonite inside the drying chamber 3, and the heating plate 34 can heat the blades of the electric stirring rod 31. The heated electric stirring rod 31 will heat the bentonite in the drying chamber 3, and the moisture inside the bentonite will be discharged from the interior of the bentonite before the device sieves the bentonite, so as to avoid the bentonite absorbing water. The bentonite expands, causing the working effect of the device to be affected. The rotating electric stirring rod 31 can also break up the bentonite. The box body 1 ensures that the bentonite is in a relatively closed space during the screening process, reducing the moisture absorbed by the bentonite during the screening process and ensuring the screening effect of the device. The electric sealing plate 32 can seal the bottom opening of the drying bin 3, which is convenient for the user to control the discharge of the bentonite in the drying bin 3. The electric sealing plate 32 can separate the drying bin 3 and the box body 1, so that the drying bin 3 can preheat the bentonite during the screening process of the bentonite by the device, thereby improving the working efficiency of the device.

[0023] Specifically, the positions of the discharge pipes 12 are staggered, and the bottom openings of the discharge pipes 12 are located at different positions.

[0024] The position of the discharge pipe 12 ensures that the discharge pipes 12 will not interfere with each other during the use of the device. The position of the bottom opening of the discharge pipe 12 is convenient for the user to collect bentonite of different sizes. The bottom opening of the discharge pipe 12 is symmetrically arranged on both sides of the discharge port 11, ensuring the discharge capacity of the discharge pipe 12.

[0025] Specifically, a plurality of reinforcing plates 14 are provided on the side wall of the box body 1 , the discharge pipe 12 penetrates the reinforcing plates 14 , and a soft cushion is provided on the side wall of the groove of the reinforcing plate 14 penetrated by the discharge pipe 12 .

[0026] The reinforcing plate 14 serves to fix the discharge pipe 12, thereby preventing the discharge pipe 12 from shaking too much during the use of the device, which would affect the stability of the connection between the discharge pipe 12 and the discharge port 13, thereby ensuring the working effect of the discharge pipe 12. By setting up several reinforcing plates 14, the working effect of the reinforcing plates 14 is ensured. The soft pads set on the grooves of the reinforcing plates 14 through which the discharge pipe 12 passes reduce the collision between the discharge pipe 12 and the reinforcing plates 14 during use, reduce the damage to the discharge pipe 12 and the reinforcing plates 14, and extend the service life of the discharge pipe 12 and the reinforcing plates 14.

[0027] Specifically, a fan 4 is provided on the top of the drying bin 3 , a filter screen 41 is provided on the passage connecting the fan 4 and the drying bin 3 , and a plurality of scrapers 42 in contact with the filter screen 41 are provided on the electric stirring rod 31 .

[0028] The fan 4 can send the moisture evaporated from the bentonite away from the interior of the drying bin 3 to prevent the moisture from affecting the drying of the bentonite in the drying bin 3. The filter screen 41 can prevent the bentonite from being sent away from the drying bin 3 by the fan 4. When the electric stirring rod 31 rotates, the scraper 42 will be rotated by the electric stirring rod 31. The rotating scraper 42 will scrape off the bentonite attached to the filter screen 41 to prevent the bentonite attached to the filter screen 41 from affecting the working effect of the fan 4. The scraper 42 is in the shape of a triangular prism, which ensures the working effect of the scraper 42.

[0029] Specifically, a mounting frame 33 is provided at the bottom opening of the drying chamber 3, and the electric stirring rod 31 is rotatably mounted on the mounting frame 33. The top surface of the support rod of the mounting frame 33 is an inclined surface inclined to both sides, and the part of the mounting frame 33 where the electric stirring rod 31 is mounted is shaped like a truncated cone.

[0030] The mounting frame 33 ensures the stability of the electric stirring rod 31 during rotation. The shape of the mounting frame 33 ensures that the mounting frame 33 will not hinder the bentonite from entering the interior of the housing 1. The top surface shape of the support rod of the electric stirring rod 31 ensures that the bentonite will not accumulate on the support rod of the electric stirring rod 31. The top size of the truncated cone part of the mounting frame 33 is the same as the size of the shaft part of the electric stirring rod 31, ensuring that the bentonite will not accumulate on the truncated cone part of the electric stirring rod 31. The shapes of the various parts of the mounting frame 33 ensure that the bentonite in the housing 1 can all enter the interior of the housing 1.

[0031] Specifically, the shape of the inner wall at the bottom of the box body 1 is a slope inclined toward the discharge port 11.

[0032] The shape of the inner wall at the bottom of the box body 1 plays a guiding role, ensuring that the bentonite that falls to the bottom of the box body 1 can be completely discharged by the discharge port 11, thereby ensuring the working effect of the discharge port 11.

[0033] Specifically, a plurality of telescopic rods 2 are provided at the bottom of the box body 1 , a spring 21 connected to the box body 1 is provided on the bottom protrusion of the telescopic rod 2 , and a rubber pad is provided on the bottom surface of the bottom protrusion of the telescopic rod 2 .

[0034] The spring 21 plays a buffering role. The box 1 will move with the spring 21 during the vibration process. The movement of the spring 21 will reduce the vibration transmitted to the ground by the box 1. The telescopic rod 2 plays a guiding role to prevent the spring 21 from deviating during the movement, which will affect the working effect of the spring 21 and the stability of the device. The telescopic rod 2 will be extended and retracted during the movement of the spring 21 to prevent the telescopic rod 2 from affecting the working effect of the spring 21. The rubber pad set on the bottom protrusion of the telescopic rod 2 increases the friction between the device and the ground, further improving the stability of the device. The rubber pad set on the bottom protrusion of the telescopic rod 2 further reduces the vibration transmitted to the ground by the box 1.

[0035] The working principle and use process of the utility model are as follows: start the vibration motor 6, add bentonite into the drying bin 3, seal the feed port of the drying bin 3, start the electric stirring rod 31 and the heating plate 34, stir and dry the bentonite, start the fan 4, the evaporated moisture is discharged from the drying bin 3 by the fan 4, the filter screen 41 filters the steam, the scraper 42 scrapes off the bentonite attached to the filter screen 41 to ensure the working effect of the fan 4, and after drying is completed, turn off the electric stirring rod 31, open the electric sealing plate 3 2. The bentonite falls onto the screen 51, the electric sealing plate 32 is closed, and new bentonite is added to the interior of the drying bin 3. The screen 51 filters the bentonite that falls onto the screen 51 under the action of vibration. The bentonite that cannot be filtered in time moves to the remaining screening bins 5 for filtration under the action of vibration. The bentonite filtered out by the screen 51 is discharged from the device through the cooperation of the discharge port 2 13 and the discharge pipe 12. The bentonite that is too large falls to the bottom of the box body 1 and is discharged from the device through the discharge port 1 11.
