Description

Technical Field

[0001] The utility model relates to the technical field of pulping tanks, in particular to a pulping tank cleaning device. Background Art

[0002] The slurry tank is a device used for slurry preparation, which is used to mix liquid and solid particulate materials through high-speed stirring to make the required suspension.

[0003] The existing pulping tank includes a tank body, an agitator arranged therein, and a water supply pipe. In order to facilitate the water supply pipe to evenly spray water into the mixture of liquid and solid particulate materials in the tank body when the agitator is stirring, thereby facilitating the mixing of solid particles, the water supply pipe is generally made into an annular pipe, which is arranged at the upper part of the tank body and connected to an external water supply pump. The annular pipe has a number of downwardly arranged water spray ports.

[0004] However, in the prior art, when the agitator stirs liquid and solid particulate materials, the outer wall of the annular tube and the water nozzle are easily adhered to by the splashing mixture. The mixture of the solid shell raw material and the liquid adheres to the water nozzle for a long time, which may block the water outlet, affect the water outlet, and easily cause uneven mixing of the liquid and solid particulate materials. In addition, the location of the water outlet is not convenient for cleaning. Utility Model Content

[0005] In order to solve the technical problems existing in the above background technology, the utility model provides a pulping tank cleaning device.

[0006] The technical solution of this utility model is as follows:

[0007] A pulping tank cleaning device is provided in the tank body of the pulping tank, an annular tube is provided along the circumference of the upper part of the tank body, a water outlet is provided at the lower part of the annular tube, the annular tube is connected to the inner wall of the tank body through a connecting piece, and an agitator shaft is provided in the middle part of the tank body along the vertical direction, including a first support rod provided on the agitator shaft, located below the annular tube, and a first cleaning unit is connected to the end of the first support rod away from the agitator shaft;

[0008] The first cleaning unit includes a mounting base and a first cleaning brush. The mounting base is detachably connected to the end of the first support rod away from the stirring shaft. The first cleaning brush is detachably connected to the upper part of the mounting base. The first cleaning brush includes a plurality of first brush filaments located directly below the annular tube. The plurality of first brush filaments extend upward until they conflict with the outer wall of the annular tube and the water outlet. The height of the first cleaning brush is adjustable.

[0009] The first cleaning unit is located below the water outlet, and its first cleaning brush can be connected to the stirring shaft through the first supporting rod, and the stirring shaft can drive the first cleaning brush to rotate, so that the first cleaning brush can timely clean the solid particle raw material mixture attached to the outer wall of the annular tube and the water outlet below the annular tube, so as to avoid the long-term adhesion of these mixtures and the clogging of the water outlet; and the height of the first cleaning brush is adjustable, and can be adjusted to a suitable contact length with the water outlet in time according to the wear of the first cleaning brush, so as to avoid the failure to clean the water outlet due to severe wear of the first cleaning brush.

[0010] The specific structure of the above-mentioned first cleaning brush is that the first cleaning brush also includes a first brush rod, the first brush rod is vertically arranged, one end of the first brush rod is threadedly connected to the mounting seat, and the first brush wire is arranged at the end of the first brush rod away from the mounting seat. When the height of the first brush wire needs to be increased, the first brush wire is driven to move toward the water outlet by unscrewing the first brush rod to a certain height.

[0011] Regarding the specific installation position of the first brush filament, a first brush filament mounting plate is provided at the upper end of the first brush rod, the first brush filament mounting plate is located directly below the rotation track of the water outlet, and the outer diameter of the first brush filament mounting plate is larger than the inner diameter of the water outlet, and the first brush filaments are covered on the upper surface of the first brush filament mounting plate.

[0012] To facilitate the first brush to extend into the water outlet to clean the inside of the water outlet during rotation, the ratio of the length of the first brush to the vertical distance from the upper surface of the first brush installation plate to the water outlet is set to 1.5-2.

[0013] The first brush rod is arranged in a vertical position, and the vertical distance between the first brush rod and the axis of the stirring shaft is consistent with the vertical distance between the water outlet and the axis of the stirring shaft.

[0014] The mounting seat can rotate, driving the first brush wire to form a certain angle with the water outlet. The mounting seat is detachably connected to the first support rod through a connecting bolt. The axis of the connecting bolt is perpendicular to the stirring shaft, and the mounting seat can rotate with the connecting bolt as the rotation axis. When the connecting screw is tightened, the mounting seat and the first support rod can be tightened.

[0015] When the above-mentioned first brush wire is in use, due to the different solid particle materials, the friction between the water outlet and the outer wall of the annular tube is different, resulting in different degrees of wear. In order to facilitate the rapid replacement of the first brush wire, a second cleaning brush symmetrically arranged with the first cleaning brush is provided at the lower part of the mounting seat. By loosening the connecting bolt, the mounting seat can be rotated to rotate the second brush wire of the second cleaning brush upwards so that it can contact the water outlet, and then tighten the connecting bolt.

[0016] In order to improve the cleaning effect of the water outlet, a second support rod symmetrically arranged with the first support rod is provided on the stirring shaft, and a second cleaning unit symmetrically arranged with the first cleaning unit is provided on the second support rod.

[0017] The beneficial effects of the present invention are:

[0018] The stirring shaft can drive the first cleaning brush to rotate under the annular tube. When the liquid and solid particle raw materials in the tank are stirred, the first brush wire can also clean the mixture adhering to the water outlet and the outer wall of the annular tube. During the period when the water outlet is spraying water, the first brush wire cooperates with the water sprayed from the water outlet to improve the cleaning effect of the water outlet and quickly flush away the mixture adhering to the water outlet and the outer wall of the annular tube.

[0019] The first brush rod of the first cleaning brush is threadedly connected to the mounting seat, so that the height of the first cleaning brush is adjustable and can be adjusted in time to a suitable contact length with the water outlet according to the wear of the first cleaning brush, thereby avoiding the first cleaning brush being severely worn and unable to clean the water outlet;

[0020] The mounting seat is configured to rotate along the axis direction of the vertical connecting bolt, so that the second brush wire of the second cleaning brush located below the mounting seat can rotate upward and interfere with the water outlet, replacing the worn first brush wire to continue cleaning the water outlet, thereby improving work efficiency.

The pulping tank cleaning device includes a first support rod 5 arranged on the stirring shaft 4, the length direction of the first support rod 5 is perpendicular to the axis of the stirring shaft 4, the first support rod 5 is located below the annular tube 2, and the end of the first support rod 5 away from the stirring shaft 4 is connected to the first cleaning unit.

[0029] Among them, see Figure 3 and Figure 4 As shown, the first cleaning unit is located below the water outlet 21, and the first cleaning unit includes a mounting base 6 and a first cleaning brush 7. The mounting base 6 is detachably connected to the end of the first support rod 5 away from the stirring shaft 4, and the first cleaning brush 7 is detachably connected to the upper part of the mounting base 6. The first cleaning brush 7 includes a first brush rod 71 and a plurality of first brush wires 72 located directly below the annular tube 2. The first brush wires 72 are prior art, and the hardness of the first brush wires 72 is selected according to actual conditions. The plurality of first brush wires 72 extend upward until they conflict with the outer wall of the annular tube 2 and the water outlet 21, and the height of the first cleaning brush 7 is adjustable.

[0030] The first brush rod 71 is disposed vertically, with the vertical spacing between the first brush rod 71 and the axis of the agitator shaft 4 being consistent with the vertical spacing between the water outlet 21 and the axis of the agitator shaft 4. One end of the first brush rod 71 is threadedly connected to the mounting base 6, and the first brush filaments 72 are disposed at the end of the first brush rod 71 away from the mounting base 6. When the height of the first brush filaments 72 needs to be increased, the first brush rod 71 is unscrewed to a certain height, thereby moving the first brush filaments 72 toward the water outlet 21. Furthermore, in this embodiment, when the first brush filaments 72 are severely worn, they can be replaced by unscrewing the first brush rod 71, making replacement simple.

[0031] See also Figure 2 and Figure 4 As shown, the specific installation position of the first brush 72 is as follows: a first brush mounting disc 9 is provided at the upper end of the first brush rod 71. The first brush mounting disc 9 is located directly below the rotation trajectory of the water outlet 21. The outer diameter of the first brush mounting disc 9 is larger than the inner diameter of the water outlet 21, and the first brush 72 covers the entire upper surface of the first brush mounting disc 9. To facilitate the first brush 72 extending into the water outlet 21 to clean the interior of the water outlet 21 during rotation, the ratio of the length of the first brush 72 to the vertical distance from the upper surface of the first brush mounting disc 9 to the water outlet 21 is set to 1.5-2.

[0032] The function achieved by the above structure is that the first cleaning brush 7 of the first cleaning unit can be connected to the stirring shaft 4 through the first support rod 5, and the stirring shaft 4 can drive the first cleaning brush 7 to rotate, so that the first cleaning brush 7 can clean the solid particle raw material mixture attached to the outer wall and the water outlet 21 under the annular tube 2 in time, so as to avoid these mixtures from being attached for a long time and clogging the water outlet 21; and the height of the first cleaning brush 7 is adjustable, and it can be adjusted to a suitable contact length with the water outlet 21 in time according to the wear of the first cleaning brush 7, so as to avoid the failure of cleaning the water outlet 21 due to severe wear of the first cleaning brush 7.

The axis of the connecting bolt 10 is perpendicular to the stirring shaft 4, and the mounting base 6 can rotate in a direction perpendicular to the axis of the connecting bolt 10. The mounting base 6 can rotate, and the mounting base 6 drives the first brush 72 thereon to form a certain angle with the water outlet 21. The first brush 72 forms a certain angle with the water outlet 21, and the inclination direction of the upper end of the first brush 72 is opposite to the rotation direction of the stirring shaft 4, not in the rotation direction of the stirring shaft 4. Compared with the vertical setting of the first brush 72 in the initial state, the inclined first brush 72 can improve the cleaning effect of the water outlet 21 and the outer wall of the annular tube 2.

[0034] See also Figure 2 As shown, the first brush 72 will wear to varying degrees during use due to differences in the friction between the water outlet 21 and the outer wall of the annular tube 2 caused by different solid particulate materials. To facilitate quick replacement of the first brush 72, a second cleaning brush 11 is provided at the bottom of the mounting base 6, symmetrically arranged with the first cleaning brush 7. When the first brush 72 is severely worn and cannot effectively clean the water outlet 21, the mounting base 6 can be rotated by loosening the connecting bolts 10. In this embodiment, the mounting base 6 is rotated 180°, and the second brush filament of the second cleaning brush 11 is rotated upward, replacing the position of the first brush 72 and contacting the water outlet 21. The connecting bolts 10 are then tightened to achieve quick replacement of the first brush 72.

[0035] See also Figure 1 and Figure 3 As shown, in order to improve the cleaning effect of the water outlet 21, a second support rod 8 symmetrically arranged with the first support rod 5 is provided on the stirring shaft 4, and a second cleaning unit symmetrical with the first cleaning unit is provided on the second support rod 8.
