Description

Technical Field

[0001] This utility model belongs to the field of slurry mixing technology, and specifically relates to a slurry mixing device. Background Technology

[0002] Chemical raw materials can generally be divided into two main categories: organic chemical raw materials and inorganic chemical raw materials. There are many types of chemical raw materials with a wide range of uses. Common chemical raw materials such as synthetic ammonia, agricultural ammonium bicarbonate, dilute nitric acid, concentrated nitric acid, sodium nitrate, sodium nitrite, mononitrotoluene, and toluidine require different processing steps during production.

[0003] Patent No. CN219596497U discloses a slurry mixing device. Slurry is fed into the inner cavity of the mixing tank through the feed pipe. The drive motor starts and drives the connecting rod to rotate. The connecting rod drives the mixing rod to rotate and mix the slurry. After mixing, the slurry is discharged through the discharge pipe. The mixing rod drives the cleaning rod to rotate, which in turn drives the cleaning cotton block and rubber strip to clean the inner wall of the mixing tank. After cleaning, the first cover plate is lifted upward. The first cover plate drives the second cover plate to move upward, and the limiting strip slides out from the limiting groove.

[0004] However, when cleaning the inner wall of the mixing tank, if some of the slurry remaining in the mixing tank has solidified and adhered firmly to the inside of the mixing tank, the wiping action of the cleaning cotton pad alone cannot completely clean the slurry, resulting in some slurry remaining in the mixing tank, which affects the cleaning of the slurry and reduces the cleaning effect. Utility Model Content

[0008] Furthermore: In order to spray cleaning agent onto the inner wall of the mixing tank by the annular airbag to soften the coagulated slurry adhering to the mixing tank, the extrusion assembly includes a plurality of pressure blocks fixedly disposed at the top of the annular scraper, and an annular pressure plate that abuts against the pressure blocks is fixed at the bottom end of the annular airbag, and the annular pressure plate is connected to the mixing tank by an elastic component.

[0009] Furthermore, to facilitate the repositioning of the annular airbag, the elastic component includes a telescopic rod fixedly disposed between the annular pressure plate and the mixing tank, and a first spring is sleeved on the outer wall of the telescopic rod.

[0010] Furthermore, in order to maintain the normal sliding of the annular plate, a sliding rod for sliding the annular plate is fixed inside the mixing tank, and a conical shovel plate sleeved on the outside of the sliding rod is fixed at the bottom end of the annular plate.

[0011] Furthermore, in order to reduce the dispersion of slurry mixture gas during the mixing process, a feed hopper is connected to one side of the mixing tank, and a cover plate is slidably provided at the top of the feed hopper. The cover plate is connected to the feed hopper through a reset assembly, and a drive assembly for moving the cover plate is provided on one side of the feed hopper.

[0012] Furthermore: In order to cover the feed hopper for automatic reset of the cover plate, the reset component includes sliders fixedly installed on both sides of the bottom end of the cover plate, and grooves for sliding of the sliders are provided on both sides of the top end of the feed hopper.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figures 1-5 The present invention provides the following technical solution:

[0026] A slurry mixing device includes: a mixing tank 1, an annular plate 2 slidably disposed inside the mixing tank 1, an electric telescopic rod 3 fixed to the top of the mixing tank 1 and fixed to the annular plate 2, an annular scraper 4 sleeved on the outer wall of the annular plate 2 and abutting against the inner wall of the mixing tank 1, an annular airbag 5 fixed at the top of the inner wall of the mixing tank 1 above the annular scraper 4, a plurality of nozzles 6 connected to the outer wall of the annular airbag 5 facing the inner wall of the mixing tank 1, a liquid inlet pipe 7 penetrating to the outside of the mixing tank 1 connected to the top of the annular airbag 5, and an extrusion assembly 8 provided on the annular scraper 4 to drive the movement of the annular airbag 5.

[0027] In this embodiment, the annular plate 2 is initially positioned at the top of the mixing tank 1, and there is no contact between the annular scraper 4 and the annular airbag 5. When it is necessary to clean the inner wall of the mixing tank 1, the annular plate 2 is first driven upward by the movement of the electric telescopic rod 3. The annular plate 2 drives the annular scraper 4 upward, thereby driving the extrusion assembly 8 to extrude the annular airbag 5. The cleaning agent in the annular airbag 5 can then be sprayed onto the inner wall of the mixing tank 1 through the nozzle 6 to soften the solidified slurry in the mixing tank 1. Then, when the electric telescopic rod 3 drives the annular plate 2 downward, the annular plate 2 drives the annular scraper 4 downward, which can scrape and clean the slurry on the inner wall of the mixing tank 1, reducing the residue of slurry on the inner wall of the mixing tank 1, facilitating the thorough cleaning of the slurry, and improving the cleaning effect of the slurry.

[0028] It should be noted that the cleaning agent can be anhydrous ethanol or acetone, etc., and the specific cleaning agent can be selected according to the raw material composition of the slurry.

[0029] In a further embodiment, such as Figure 3 As shown, the extrusion assembly 8 includes multiple pressure blocks 81 fixedly disposed at the top of the annular scraper 4, and an annular pressure plate 82 fixed at the bottom of the annular airbag 5, which abuts against the pressure blocks 81. The annular pressure plate 82 is connected to the mixing tank 1 through an elastic assembly 9. The elastic assembly 9 includes a telescopic rod 91 fixedly disposed between the annular pressure plate 82 and the mixing tank 1, and a first spring 92 is sleeved on the outer wall of the telescopic rod 91.

[0030] When the electric telescopic rod 3 drives the annular plate 2 to move upward, the annular plate 2 drives the annular scraper 4 to move upward. The annular scraper 4 drives the pressure block 81 to squeeze the annular pressure plate 82, which in turn squeezes the annular airbag 5, causing the annular airbag 5 to spray cleaning agent through the nozzle 6. At this time, the first spring 92 is in a compressed state. When the electric telescopic rod 3 drives the annular plate 2 to move downward, there is no contact between the pressure block 81 and the annular pressure plate 82. Then, under the elastic action of the first spring 92, the annular pressure plate 82 is reset, and the annular pressure plate 82 stops squeezing the annular airbag 5.

[0031] In a further embodiment, such as Figure 3As shown, a sliding rod 10 for sliding an annular plate 2 is fixed inside the mixing tank 1, and a conical shovel plate 11 sleeved on the outside of the sliding rod 10 is fixed at the bottom end of the annular plate 2.

[0032] When the annular plate 2 moves up and down, it slides on the slide rod 10. The slide rod 10 can provide auxiliary support for the annular plate 2, maintaining the stability of its up and down movement. When the annular plate 2 moves down, the conical shovel 11 can scrape the slurry adhering to the slide rod 10, avoiding interference with the normal sliding of the annular plate 2.

[0033] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a feed hopper 12 is connected to one side of the mixing tank 1. A cover plate 13 is slidably provided at the top of the feed hopper 12. The cover plate 13 is connected to the feed hopper 12 through a reset assembly 14. A drive assembly 15 is provided on one side of the feed hopper 12 to drive the cover plate 13 to move.

[0034] When material is fed through the feed hopper 12, the movement of the drive component 15 drives the movement of the cover plate 13, opening the feed hopper 12 so that material can be fed into the feed hopper 12. After feeding is completed, the movement of the reset component 14 drives the cover plate 13 to reset, blocking the feed hopper 12, thereby preventing the slurry gas from drifting during the mixing process, avoiding environmental pollution, and improving the safety of slurry mixing.

[0035] In a further embodiment, such as Figure 4-5 As shown, the reset assembly 14 includes sliders 141 fixedly disposed on both sides of the bottom end of the cover plate 13. The top end of the feed hopper 12 has grooves 142 on both sides for the sliders 141 to slide. The grooves 142 are fixedly connected to the sliders 141 by a second spring 143. The drive assembly 15 includes a rotating rod 151 rotatably disposed on one side of the feed hopper 12. A first connecting rod 152 is sleeved on the outer wall of the rotating rod 151. One end of the first connecting rod 152 is hinged to a second connecting rod 153 hinged to the cover plate 13. The drive assembly 15 also includes a handle 154 and a fastening nut 155. The handle 154 is fixed to the end of the rotating rod 151, and the fastening nut 155 is threaded on the outer wall of the rotating rod 151.

[0036] When feeding is required, manually turn the handle 154. The handle 154 drives the rotating rod 151 to rotate, which in turn drives the first connecting rod 152 to rotate. The first connecting rod 152 drives the second connecting rod 153 to move, thereby pushing the cover plate 13 to move. The cover plate 13 gradually opens the feed hopper 12. At the same time, the movement of the cover plate 13 drives the slider 141 to stretch the second spring 143. When the feed hopper 12 is fully open, manually turn the fastening nut 155 to make the fastening nut 155 close to the feed hopper 12. When the two parts collide, the rotating rod 151 is fixed, thereby fixing the cover plate 13, allowing material to be fed through the feed hopper 12. After feeding is completed, the fastening nut 155 is rotated in the opposite direction to loosen the rotating rod 151. At this time, under the elastic action of the second spring 143, the slider 141 is driven to reset, and the slider 141 drives the cover plate 13 to reset, thus sealing and blocking the feed hopper 12, thereby preventing the slurry gas from drifting during the mixing process, avoiding environmental pollution, and improving the safety of slurry mixing.

[0037] The working principle of a slurry mixing device is as follows: When feeding is required, the handle 154 is manually turned, which drives the rotating rod 151 to rotate. The rotating rod 151 drives the first connecting rod 152 to rotate, and the first connecting rod 152 drives the second connecting rod 153 to move, thereby pushing the cover plate 13 to move. When the feeding hopper 12 is fully open, the fastening nut 155 is manually turned to fix the rotating rod 151, thereby fixing the cover plate 13, and feeding can then be done through the feeding hopper 12. After feeding is completed, the fastening nut 155 is turned in the opposite direction to loosen the rotating rod 151. At this time, under the elastic action of the second spring 143, the slider 141 is driven to reset, and the slider 141 drives the cover plate 13 to reset, thereby sealing and blocking the feeding hopper 12, thus preventing the slurry gas from drifting during the mixing process, avoiding environmental pollution, and improving the safety of slurry mixing.

[0038] After the slurry is mixed and discharged from the mixing tank 1, the inner wall of the mixing tank 1 needs to be cleaned. Under the movement of the electric telescopic rod 3, the annular plate 2 is first driven to move upward. The annular plate 2 drives the annular scraper 4 to move upward. The annular scraper 4 drives the pressure block 81 to squeeze the annular pressure plate 82. The annular pressure plate 82 squeezes the annular airbag 5. The cleaning agent in the annular airbag 5 can then be sprayed onto the inner wall of the mixing tank 1 through the nozzle 6 to soften the solidified slurry in the mixing tank 1. Then, when the electric telescopic rod 3 drives the annular plate 2 to move downward, the annular plate 2 drives the annular scraper 4 to move downward, which can scrape and clean the slurry on the inner wall of the mixing tank 1, reduce the slurry residue on the inner wall of the mixing tank 1, facilitate the thorough cleaning of the slurry, and improve the cleaning effect of the slurry.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
