Description

Technical Field

[0001] The utility model relates to the technical field of fermentation, in particular to a papermaking pulp slag removal device. Background Art

[0002] Among the raw materials for papermaking in my country, waste paper accounts for more than 65%. When waste paper is used as raw material for papermaking, after the waste paper is shredded, heavy impurities such as iron, sand, pulp lumps, pulp blocks, rubber blocks, nails, etc. with a relatively large specific gravity are also included in the pulp. Usually, slag removal equipment is required to remove the impurities in the pulp.

[0003] When the existing slag removal equipment is in use, most of them discharge impurities in the slurry through the centrifugal force of rotation. A stirring device is required to disperse the raw materials and expose the residue wrapped in the raw materials for easy discharge. However, the relative rotation speed between the existing stirring equipment and the slag removal equipment is limited during stirring, which affects the separation effect.

[0004] Therefore, we propose a papermaking pulp deslagging device. Utility Model Content

[0018] Beneficial Effects

[0019] The utility model provides a papermaking pulp slag removal device, which has the following beneficial effects:

[0020] (1) This paper pulp slag removal device, by providing a stirring component, a slag removal component and a driving component, increases the relative rotation speed between the dispersion blades and the separation cylinder by reversing the separation cylinder and the dispersion blades, thereby increasing the degree of dispersion of the raw material by the dispersion blades, thereby preventing the residue from being wrapped in the raw material and being difficult to remove.

[0021] (2) This paper pulp slag removal device, through the arrangement of balls, the balls rotatably connected on the first fixed ring and the second fixed ring can reduce the friction between the two, thereby improving the smoothness of the rotation of the separation cylinder, and through the arrangement of the first fixed ring and the second fixed ring, the top of the separation cylinder is supported, thereby improving the stability of the rotation of the separation cylinder.

[0022] (3) The paper pulp slag removal device has a pressure relief hole that allows the raw material to pass through and release pressure, thereby preventing the dispersion fan blades from being worn due to excessive stress.

[0023] (4) This paper pulp slag removal device has a pressure plate and a conical rod. The pressure plate is designed so that when the dispersion fan blades rotate with the rotating shaft, the convex design of the pressure plate can guide the dispersion of the raw materials on the pressure plate through the convex surface of the pressure plate, thereby avoiding damage to the pressure plate due to excessive stress. When too much raw material is retained on the pressure plate, the pressure plate can be squeezed and the return spring can be driven to contract. At this time, the conical rod passes through the through hole, and the raw material can be dispersed through the conical surface of the conical rod, thereby improving the dispersion degree of the raw material and improving the slag removal effect.

[0035] like Figure 2 and Figure 3 As shown, the servo motor 2 is fixedly connected to the axial position at the top of the slag removal equipment body 1 through a motor frame, the rotating shaft 6 is fixedly connected to the output end of the servo motor 2, the connecting rods 7 are arranged in a circle and fixedly connected to the outer wall of the rotating shaft 6, and the dispersion blades 8 are fixedly connected to the connecting rods 7 away from one end of the rotating shaft 6 and are located in the separation cylinder 9.

[0036] A material discharge base 10 is fixedly connected to the inner wall at the bottom of the slag removal equipment body 1. Both ends of the cross section of the material discharge base 10 are inclined. The separation cylinder 9 is rotatably connected to the top position of the material discharge base 10. A plurality of slag discharge holes 11 arranged in a circle are provided on the inner wall of the separation cylinder 9. A through groove is provided at the bottom of the separation cylinder 9.

[0037] A plurality of circumferentially arranged fixing rods 12 are fixedly connected to the top of the outer wall of the rotating shaft 6, and an annular connecting ring 13 is fixedly connected to the outer wall of the fixing rod 12. A plurality of circumferentially arranged first gear grooves are opened at the bottom of the inner ring of the connecting ring 13.

[0038] The second fixed ring 17 is fixedly connected to the top position of the outer ring of the separation cylinder 9, and a plurality of second gear grooves arranged in a circumferential manner are provided on the top of the second fixed ring 17.

[0039] By setting the ball 18, the ball 18 rotatably connected on the first fixing ring 14 and the second fixing ring 17 can reduce the friction between the two, thereby improving the smoothness of the rotation of the separation cylinder 9. In addition, by setting the first fixing ring 14 and the second fixing ring 17, the top of the separation cylinder 9 is supported, thereby improving the stability of the rotation of the separation cylinder 9.

[0042] like Figure 4 As shown, the outer wall of the dispersion blade 8 is provided with a plurality of pressure relief holes 19 arranged in a matrix, and the pressure relief holes 19 are columnar grooves with arc-shaped ends at the cross-section.

[0043] Through the set pressure relief hole 19, the pressure relief hole 19 can allow the raw material to pass through and release pressure, thereby avoiding excessive stress on the dispersion fan blades 8 and causing wear on the dispersion fan blades 8. The arc-shaped design of the pressure relief hole 19 can prevent the raw material from being blocked in the pressure relief hole 19 when passing through the pressure relief hole 19, thereby affecting the discharge and pressure relief of the raw material.

A through hole 21 is opened on the pressure plate 20. The through hole 21 and the conical rod 22 are located at the same axial position, and the pressure plate 20 is convex.

[0045] By setting up the pressure plate 20 and the conical rod 22 and the design of the pressure plate 20, when the dispersing blades 8 rotate with the rotating shaft 6, the convex design of the pressure plate 20 can guide the dispersion of the raw materials on the pressure plate 20 through the convex surface of the pressure plate 20, thereby avoiding damage to the pressure plate 20 caused by excessive stress. When too much raw material is retained on the pressure plate 20, the pressure plate 20 can be squeezed and the return spring 23 can be driven to contract. At this time, the conical rod 22 passes through the through hole 21, and the raw materials can be dispersed through the conical surface of the conical rod 22, thereby improving the dispersion degree of the raw materials and improving the slag removal effect.

[0046] The working principle of the utility model is as follows: when slag removal is required, the raw materials are added into the separation drum 9 in the slag removal equipment body 1 through the servo motor 2. At this time, the servo motor 2 is turned on. The servo motor 2 can drive the dispersion blades 8 to rotate through the rotating shaft 6 and the connecting rod 7 to disperse the raw materials. The rotation of the rotating shaft 6 can drive the connecting ring 13 to rotate through the fixed rod 12. The rotation of the connecting ring 13 drives the transmission gear 16 to rotate in the same direction through the gear groove. The rotation of the transmission gear 16 can drive the second fixed ring 17 to rotate in the opposite direction through the second gear groove meshing thereon, and then drive the separation drum 9 and the connecting ring 13 to rotate in the opposite direction, and then the separation drum 9 and the dispersion blades 8 rotate in the opposite direction. The separation drum 9 drives the residue in the raw material to rotate by rotation, and the residue is discharged through the slag discharge hole 11 through the centrifugal force of the rotation of the separation drum 9, and is discharged through the slag discharge port 4 through the inclined part of the unloading base 10. After completion, the solenoid valve on the discharge port 5 is opened to discharge the raw materials after slag removal.
