Description

Technical Field

[0001] The utility model relates to the technical field of pulping tank stirring devices, in particular to a stirring device for a pulping tank capable of screening out coarse particles. Background Technique

[0002] In the production process of aerated concrete blocks, a pulping tank is used to mix and stir cement, lime, gypsum and other gelling materials with aggregates such as sand and fly ash, as well as water, foaming agent, etc. to form a uniform slurry. Subsequently, the slurry is injected into a mold and finally made into aerated concrete blocks through processes such as curing and cutting.

[0003] The patent document with the publication number CN215233439U discloses a pulping tank for making dry fly ash for concrete block production. The key points of its technical solution are: including a pulping tank, a water inlet hole is opened on one side of the pulping tank, a water inlet pipe is fixedly sleeved inside the water inlet hole, a slurry outlet hole is opened on one side of the pulping tank, and a solenoid valve is fixedly sleeved inside the slurry outlet hole. Water is injected into the inside of the pulping tank through the water inlet pipe. By opening the set ash discharge valve, dry fly ash is evenly spread inside the pulping tank through the ash discharge valve. Through the set first driving motor, the driving shaft of the first driving motor rotates clockwise to drive the first fixed block and the first stirring rod to rotate. Through the set second driving motor, the driving shaft of the second driving motor rotates counterclockwise to drive the second fixed block and the second stirring rod to rotate. Through the first stirring rod and the second stirring rod rotating in opposite directions, the slurry is stirred more evenly.

[0004] The above device puts materials such as cement, lime, and gypsum that need to be used into the inside of the pulping tank through the feeding holes inside the ash storage bin for stirring. However, some coarse particles are easily mixed in materials such as cement, lime, and gypsum. These coarse particles will affect the uniformity and stability of the slurry during stirring, and even have an adverse impact on subsequent production processes and product quality. Content of the Utility Model

[0005] Aiming at the above problems, a stirring device for a pulping tank capable of screening out coarse particles is provided. By rotating the crushing roller, the raw materials can be crushed to prevent some large raw materials from entering the inside of the stirring barrel, resulting in the inability to stir the raw materials. After the crushed raw materials pass through the coarse screen, they will fall into the inside of the stirring barrel. The coarse screen can be used to filter out the coarse particles in the crushed raw materials to avoid these coarse particles affecting the quality of the slurry during stirring. After the coarse screen is used for a period of time, it can be taken out to facilitate the cleaning of the coarse particles accumulated on the surface of the coarse screen.

[0006] In order to solve the problems of the prior art, the utility model provides a stirring device for a pulping pool capable of screening out coarse particles, comprising a stirring barrel, a feeding frame is arranged on the top of the stirring barrel, and the interior of the feeding frame is communicated with the interior of the stirring barrel, symmetrical crushing rollers are rotatably arranged inside the feeding frame, support blocks are arranged on the inner walls on both sides of the feeding frame, symmetrical spring telescopic rods are arranged on the top of the support blocks, a clamping frame is arranged at the telescopic end of the spring telescopic rod, a coarse screen plate is slidably arranged inside the clamping frame, a plurality of elastic protrusions are arranged inside the clamping frame, a groove matched with the elastic protrusion is provided at the bottom of the coarse screen plate, and a notch for the movement of the coarse screen plate is provided on the side wall of the feeding frame.

[0007] Preferably, a stirring rod for stirring the raw materials is rotatably arranged inside the stirring barrel, and a scraper block is arranged outside the stirring rod to abut against the inner wall of the stirring barrel.

[0008] Preferably, one end of the two crushing rollers is provided with circular gears meshing with each other, a first rotating rod is provided outside one of the circular gears, a second bevel gear is provided outside the first rotating rod, and a second rotating rod is provided outside the other circular gear.

[0009] Preferably, a support plate is provided on the top of the mixing barrel, a motor is provided on the top of the support plate, the output shaft of the motor is provided with a drive shaft through a coupling, the bottom of the drive shaft is connected to the top of the mixing rod, and the outside of the drive shaft is provided with a first bevel gear meshing with a second bevel gear.

[0010] Preferably, a rotating rod is rotatably arranged inside the feed frame, one end of the rotating rod extends to the outside of the feed frame, and an abutment block abutting against the clamping frame is arranged outside the rotating rod.

[0011] Preferably, the rotating rod and the second rotating rod are both provided with synchronous wheels on their exteriors, and the two synchronous wheels are connected via a synchronous belt transmission.

[0012] Preferably, the outside of the mixing barrel is connected to a discharge valve for discharging materials.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The driving shaft and the first bevel gear are driven to rotate by a motor. While the first bevel gear rotates, it will also drive the second bevel gear to rotate, thereby driving two circular gears to rotate relative to each other. Further, two crushing rollers are driven to rotate to crush the raw materials, preventing some large raw materials from entering the interior of the mixing barrel, which may cause the inability to mix the raw materials. After being crushed, the raw materials will fall into the interior of the mixing barrel through a coarse sieve. The coarse sieve can filter out the coarse particles in the crushed raw materials, avoiding the influence of these coarse particles on the quality of the slurry produced during mixing. After the coarse sieve has been used for a period of time, it can be taken out for convenient cleaning of the coarse particles accumulated on its surface.

[0015] 2. To prevent the filter holes of the coarse sieve from being blocked during operation, one of the gears drives the second rotating rod to rotate while rotating. When the second rotating rod rotates, it works with a synchronous pulley and a synchronous belt to drive the rotating rod to rotate, and further drives the abutting block to rotate. The abutting block is used to abut against the card frame, and the card frame moves upward under the extrusion of the abutting block. When the abutting block moves away from the card frame, the card frame resets under the action of the spring telescopic rod. The rotating abutting block can keep the card frame in a vibrating state all the time, and at the same time, the coarse sieve plate inside the card frame is also in a vibrating state. In this way, the filter holes inside the card frame are effectively prevented from being blocked. To prevent the card frame from moving during vibration, elastic bumps are used in cooperation with the bottom of the card frame to limit the position of the card frame.

Detailed implementation manners

[0023] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0024] As Figures 1 to 6 shown, the present invention provides:

[0025] A stirring device for a pulping pond capable of screening out coarse particles, comprising a stirring barrel 1. A feeding frame 2 is arranged at the top of the stirring barrel 1, and the inside of the feeding frame 2 is communicated with the inside of the stirring barrel 1. Symmetric crushing rollers 12 are rotatably arranged inside the feeding frame 2. Support blocks 17 are arranged on both inner walls of the feeding frame 2. Symmetric spring telescopic rods 19 are arranged at the tops of the support blocks 17. The telescopic ends of the spring telescopic rods 19 are provided with clamping frames 18. A coarse sieve plate 9 is slidably arranged inside the clamping frame 18. A plurality of elastic convex blocks 21 are arranged inside the clamping frame 18. Grooves adapted to the elastic convex blocks 21 are formed at the bottom of the coarse sieve plate 9. A notch for the movement of the coarse sieve plate 9 is formed in the side wall of the feeding frame 2.

[0026] By rotating the crushing rollers 12, the raw materials can be crushed to prevent some large raw materials from entering the inside of the stirring barrel 1, resulting in the inability to stir the raw materials. After the crushed raw materials pass through the coarse sieve mesh, they will fall into the inside of the stirring barrel 1. The coarse sieve mesh can be used to filter out the coarse particles in the crushed raw materials to avoid the influence of these coarse particles on the quality of the produced slurry during stirring. After the coarse sieve mesh is used for a period of time, it can be taken out to facilitate the cleaning of the coarse particles accumulated on the surface of the coarse sieve mesh. In order to prevent the clamping frame 18 from moving during vibration, the elastic convex blocks 21 are used to cooperate with the bottom of the clamping frame 18 to limit the clamping frame 18.

[0027] Figure 6 As shown, a stirring rod 22 for stirring raw materials is rotatably arranged inside the stirring barrel 1, and scraping blocks 23 abutting against the inner wall of the stirring barrel 1 are arranged outside the stirring rod 22.

[0028] The stirring rod 22 can be used to fully stir the raw materials entering the inside of the stirring barrel 1, and at the same time, the scraping blocks 23 can be used to remove the raw materials adhering to the inner wall of the stirring barrel 1.

[0029] AsFigure 3 As shown in the figure, at one end of two crushing rollers 12, there are circular gears 11 engaged with each other. Outside one of the circular gears 11, there is a first rotating rod 10. Outside the first rotating rod 10, there is a second bevel gear 8. Outside the other circular gear 11, there is a second rotating rod 13.

[0030] By the mutual rotation of the two circular gears 11, the two crushing rollers 12 are further driven to rotate, so as to crush the raw materials.

[0031] As Figure 2 shown in the figure, at the top of the stirring barrel 1, there is a support plate 3. At the top of the support plate 3, there is a motor 4. The output shaft of the motor 4 is provided with a driving shaft 6 through a coupling. The bottom of the driving shaft 6 is connected to the top of the stirring rod 22. Outside the driving shaft 6, there is a first bevel gear 7 engaged with the second bevel gear 8.

[0032] By driving the driving shaft 6 and the first bevel gear 7 to rotate by the motor 4, while the first bevel gear 7 rotates, it will also drive the second bevel gear 8 to rotate.

[0033] As Figure 3 and Figure 4 shown in the figure, inside the feeding frame 2, there is a rotating rod 16 rotatably arranged. One end of the rotating rod 16 extends outside the feeding frame 2. Outside the rotating rod 16, there is a contact block 20 in contact with the clamping frame 18.

[0034] By using the contact block 20 to contact the clamping frame 18, the clamping frame 18 moves upward under the extrusion of the contact block 20. When the contact block 20 moves away from the clamping frame 18, the clamping frame 18 resets under the action of the spring telescopic rod 19. By using the rotating contact block 20, the clamping frame 18 can be kept in a vibrating state all the time. At the same time, the coarse sieve plate 9 inside the clamping frame 18 is also in a vibrating state, thus effectively preventing the filter holes inside the clamping frame 18 from being blocked.

[0035] As Figure 3 shown in the figure, outside both the rotating rod 16 and the second rotating rod 13, there are synchronous wheels 15. The two synchronous wheels 15 are connected by a synchronous belt 14.

[0036] The rotating rod 16 and the second rotating rod 13 can be driven to rotate simultaneously through the synchronous wheels 15.

[0037] As Figure 6 shown in the figure, the outside of the stirring barrel 1 is communicated with a discharge valve 5 for discharging materials.

[0038] The mixed raw materials can be discharged through the discharge valve 5.

[0039] The above embodiments only illustrate one or several implementation manners of the stirring device for a pulping pond capable of screening out coarse particles of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the appended claims.
