Description

Technical Field

[0002] In the production process of paper-plastic products, in order to give the products special functions (such as waterproof, moisture-proof, antistatic, etc.), the slurry needs to be adjusted. The specific process is to put the pulp and a small amount of functional additives into the slurry mixing device, and add clean water or white water, and adjust the slurry to the concentration required for molding through the slurry mixing device.

[0003] The prior art discloses an automated controlled slurry mixing tank with patent announcement number CN218508125U. The above patent can accurately control the ratio and content of slurry and water injected into the tank body by adopting an electrically controlled metering valve, and can effectively increase the efficiency of stirring and mixing by adopting pre-stirring, controlled range stirring and secondary stirring, and the slurry mixing effect is better. However, the following deficiencies still exist in actual use: the stirring parts inside the existing slurry mixing device are usually fixed, the stirring range is relatively fixed, the slurry is not stirred evenly, resulting in poor stirring effect, and the slurry mixing device is mostly cleaned manually by staff using tools. Thicker slurry is easy to adhere to the inner wall of the slurry mixing device and is difficult to clean, which increases the difficulty of the staff's work and reduces the cleaning efficiency.

[0004] Therefore, a slurry mixing device with a cleaning function is needed to solve the problems in the prior art that the fixed stirring member in the slurry mixing device easily leads to low slurry mixing efficiency and the thick slurry adheres to the inner wall of the slurry mixing device and is difficult to clean.

[0009] It is further worth explaining that a servo motor is fixedly connected at the center of the top surface of the cross plate, and a transmission shaft is coaxially fixedly connected to the output end of the servo motor. The bottom end of the transmission shaft rotates through the bottom surface of the cross plate and is rotatably connected to the inner wall of the bottom end of the slurry mixing tank. Four circumferentially distributed connecting rods are fixedly connected to the bottom of the outer surface of the transmission shaft, and a scraper is fixedly connected to the outer wall of the connecting rod on the side away from the transmission shaft.

[0010] It should be further explained that the four outer walls of the cross plate are fixedly connected to a second motor, and the output end of the second motor is coaxially fixedly connected to a reciprocating screw. Each of the reciprocating screws rotates through one end wall inside a corresponding movable groove and is rotatably connected to the other end wall inside the groove.

[0011] As a preferred implementation, the stirring shaft and the reciprocating screw on each of the movable plates are staggered, and the top surface of the annular tube is fixedly connected to the bottom surface of the cross plate.

[0012] As a preferred embodiment, the annular tube is located above the stirring blades, and the scraper is located below the annular tube with one side outer wall in contact with the inner surface of the slurry mixing tank.

[0013] Compared with the prior art, the pulp mixing device with cleaning function provided by the utility model has at least the following beneficial effects:

[0014] (1) Through the cooperation of the reciprocating screw and the stirring mechanism, the first motor drives the stirring shaft and the stirring blade to rotate, and the second motor drives the reciprocating screw to rotate.

[0024] Further as Figure 1 and Figure 2 As shown, it is worth specifically explaining that the cleaning component 5 includes a water tank 51, the outer wall of one end of the water tank 51 is fixedly connected to one end of the outer surface of the slurry mixing tank 1, one side of the top surface of the water tank 51 is fixedly connected with a liquid inlet pipe 52, a water pump 53 is installed on the top surface of the water tank 51, the output end of the water pump 53 is fixedly connected with a delivery pipe 54, the end of the delivery pipe 54 away from the water pump 53 is fixedly connected with an annular pipe 55, and the outer surface of the annular pipe 55 is fixedly connected with a plurality of nozzles 56 distributed in a circle.

[0025] Further as Figure 1 and Figure 4 As shown, it is worth explaining in detail that a servo motor 7 is fixedly connected at the center of the top surface of the cross plate 3, and a transmission shaft 8 is coaxially fixedly connected to the output end of the servo motor 7. The bottom end of the transmission shaft 8 rotates through the bottom surface of the cross plate 3 and is rotatably connected to the inner wall of the bottom end of the slurry mixing tank 1. Four circumferentially distributed connecting rods 9 are fixedly connected to the bottom of the outer surface of the transmission shaft 8, and a scraper 10 is fixedly connected to the outer wall of the connecting rod 9 away from the transmission shaft 8.

[0026] Further as Figure 1 and Figure 3 As shown, it is worth explaining in detail that the four outer walls of the cross plate 3 are fixedly connected to the second motor 11, and the output end of the second motor 11 is coaxially fixedly connected to the reciprocating screw 12, each reciprocating screw 12 rotates through one end wall inside a corresponding movable groove 41 and is rotatably connected to the other end wall inside it, and each reciprocating screw 12 is threadedly connected to a corresponding movable plate 44.

After the water pump 53 is started, the cleaning liquid in the water storage tank 51 is pumped out and sent into the annular tube 55 through the delivery pipe 54, and then sprayed to the inner wall of the slurry mixing tank 1 through multiple nozzles 56, so as to wash away part of the slurry attached to the inner wall of the slurry mixing tank 1. At the same time, the servo motor 7 drives the transmission shaft 8 to rotate, and the rotating transmission shaft 8 drives the scraper 10 to rotate through the connecting rod 9. The rotating scraper 10 scrapes off the slurry attached to the inner wall of the slurry mixing tank 1, and the scraped slurry is washed with the sprayed cleaning liquid, so that the cleaning effect is good, and the brushed slurry is discharged through the discharge pipe 6. The operation is simple, and the problem of thick slurry attached to the inner wall of the slurry mixing device being difficult to clean is effectively avoided.
