Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shearing machines, in particular to a high-safety magnetic flocculation shearing machine convenient to disassemble, assemble and overhaul. BACKGROUND

[0002] The magnetic flocculation precipitation technology is a commonly used technology in sewage treatment, which adds magnetic powder in the flocculation stage to increase the specific gravity of the flocculation, so that the flocculation can quickly precipitate, and the magnetic powder can be recycled by using the magnetic attraction principle due to its magnetic characteristics. Before recycling the magnetic powder, the magnetic powder in the flocculation is separated from the colloid, and then recycled by a magnetic recycling device.

[0003] At present, the equipment for separating magnetic powder mainly uses a shearing machine. For example, a magnetic flocculation ceramic shearing machine disclosed in a patent with the authorization announcement No. CN210994597U includes a motor, a stirring support and a transmission shaft. The motor is installed above the stirring support, and the motor is connected with the transmission shaft through a shaft coupling. The stirring support and the lower ceramic shearing cylinder are installed together. The stirring support is internally provided with a shaft coupling. The transmission shaft penetrates the ceramic mechanical seal into the ceramic shearing cylinder. A magnetic sludge outlet is welded on the left upper part of the ceramic shearing cylinder. A magnetic sludge inlet is welded on the right lower part of the ceramic shearing cylinder. The magnetic sludge outlet, the ceramic shearing cylinder and the magnetic sludge inlet jointly form a Z-shaped flow type. The ceramic shearing disc is provided with a knife edge around the ceramic shearing disc, and the outer surface of the ceramic shearing disc is a frosted surface.

[0004] The patent shears the magnetic flocculation by high-speed rotation of the ceramic shearing disc. The ceramic shearing disc is installed on the transmission shaft. The transmission shaft is linked with the motor through the shaft coupling, which is similar to the structure of the current shearing machine. However, this shearing machine has some problems in shearing the magnetic flocculation. For example, the amount of colloid, the amount of magnetic powder and the amount of solid impurities in the magnetic flocculation after sewage treatment of different water quality are different. If the same shearing force is used to shear the magnetic flocculation, the wear of the shearing disc will be accelerated, and the service life of the shearing disc will be reduced. The current shearing machine cannot adjust the shearing force in real time according to different magnetic flocculation. SUMMARY

DETAILED DESCRIPTION

[0048] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application and uses. It should be understood that throughout the drawings, the same or similar reference numerals can be used for the same or similar items in the various figures. The various drawings can schematically represent the concepts and principles of the embodiments of the present disclosure and do not necessarily show the specific dimensions and ratios of the various embodiments of the present disclosure. Certain parts in certain drawings can be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0049] Embodiment 1

[0050] Referring to Figure 1 and Figure 2 , a high-safety magnetic flocculation shear machine convenient for disassembly, assembly and maintenance is provided, which comprises a main cylinder 1 and a shear shaft 2. The outer surface of the shear shaft 2 is uniformly fixed with a shear cutter 21. The shear shaft 2 is rotationally connected in the main cylinder 1. The outer surface of the main cylinder 1 is fixed with a feeding flange pipe 11 and a discharging flange pipe 12. The feeding flange pipe 11 and the discharging flange pipe 12 are respectively used for feeding and discharging. Exemplarily, the magnetic flocculation enters through the feeding flange pipe 11, and the magnetic flocculation is sheared by the shear cutter 21 driven by the high-speed rotation of the shear shaft 2. The sheared magnetic flocculation is discharged through the discharging flange pipe 12.

[0051] Further, referring to Figure 2 and Figure 3As shown, the fixed cutter barrel 3 is fixed in the main barrel 1 to cooperate with the shearing shaft 2 to shear magnetic flocculation. The inner wall of the fixed cutter barrel 3 is fixed with fixed cutters 31 staggered. The shearing cutters 21 and the fixed cutters 31 are staggered in up and down directions. The staggered shearing force is formed by the staggered shearing cutters 21 and the fixed cutters 31, so as to improve the shearing effect of magnetic flocculation. The shearing degree can be controlled by controlling the distance between the shearing cutters 21 and the fixed cutters 31. For example, the smaller the distance between the shearing cutters 21 and the fixed cutters 31, the greater the extrusion force received by the shearing, that is, the greater the shearing degree, and vice versa.

[0052] Specifically, referring to Figure 2 and Figure 3 As shown, the two ends of the main barrel 1 are rotatably and sealingly connected with a transmission seat 101 and a sleeve 102, respectively. The two ends of the main barrel 1 are fixed with a first end cover 13 and a second end cover 14, respectively. The transmission seat 101 and the sleeve 102 are rotatably and sealingly connected with the first end cover 13 and the second end cover 14, respectively. The two ends of the shearing shaft 2 are slidingly connected with the transmission seat 101 and the sleeve 102, respectively. The first end cover 13 is fixed with a driving motor 4. The output end of the driving motor 4 is fixedly connected with the transmission seat 101. The driving motor 4 is connected with the shearing shaft 2 through the transmission seat 101. The purpose is to separate the shearing shaft 2 from the transmission seat 101, so as to facilitate disassembly and maintenance.

[0053] More specifically, referring to Figure 4 , Figure 6 , Figure 7 and Figure 10 As shown, the inner wall of the transmission seat 101 is uniformly fixed with first protrusions 1011. The outer surface of one end of the shearing shaft 2 is uniformly provided with first tooth grooves 22 matched with the first protrusions 1011. The first protrusions 1011 and the first tooth grooves 22 are slidingly connected. The outer surface of the other end of the shearing shaft 2 is uniformly provided with second tooth grooves 23. The inner wall of the sleeve 102 is uniformly fixed with second protrusions 1021 matched with the second tooth grooves 23. The second tooth grooves 23 and the second protrusions 1021 are slidingly connected. The two ends of the shearing shaft 2 are sleeved with springs 201. The springs 201 are used to provide elastic force for the shearing shaft 2. Specifically, two springs 201 are arranged in the transmission seat 101 and the sleeve 102, respectively.

[0054] The driving motor 4 drives the transmission seat 101 to rotate, and the transmission seat 101 drives the shearing shaft 2 to rotate through the cooperation of the first protruding teeth 1011 and the first tooth groove 22, and does not affect the axial movement of the shearing shaft 2 in the transmission seat 101, that is, the up and down movement, thereby controlling the position of the shearing shaft 2, that is, changing the distance between the shearing cutter 21 and the fixed cutter 31, so as to change the shearing force of the magnetic flocculation; for example, the smaller the distance between the shearing cutter 21 and the fixed cutter 31, the greater the shearing pressure applied to the magnetic flocculation, and the greater the shearing force; and one end of the shearing shaft 2 can be stably transmitted through the transmission seat 101, and the other end of the shearing shaft 2 can be stably rotated through the sleeve 102 and the second end cover 14, and does not affect the axial movement of the shearing shaft 2.

[0055] It is worth mentioning that, referring to Figure 3 , the outer surface of the first end cover 13 is fixed with a positioning block 131, and the end of the fixed cutter barrel 3 is provided with a positioning groove 32, and the positioning block 131 is clamped with the positioning groove 32, so as to limit the fixed cutter barrel 3; the purpose is to facilitate the fixed cutter barrel 3 to be fixed in the main barrel 1, and facilitate the disassembly and maintenance of the fixed cutter barrel 3; it should be noted that the end of the fixed cutter barrel 3 away from the first end cover 13 can be quickly connected with the main barrel 1 through the snap spring or the buckle and the like.

[0056] Specifically, referring to Figure 2 , Figure 3 and Figure 4 , the second end cover 14 is provided with an adjusting mechanism 5, which is used for adjusting the distance between the shearing shaft 2 and the fixed cutter barrel 3 to control the shearing force of the shearing magnetic flocculation, and the adjusting mechanism 5 comprises a second fixed seat 51, a pressing ring 52 and an adjusting ring 53, the second fixed seat 51 is fixed on the second end cover 14, the pressing ring 52 is in sliding connection with the second fixed seat 51, and the pressing ring 52 is in abutment with the shearing shaft 2 through the spring 201.

[0057] More specifically, referring to Figure 5 , Figure 8 and Figure 9 , the adjusting ring 53 is in rotational connection with the second fixed seat 51, the adjusting ring 53 is linked with the shearing shaft 2 through the pressing ring 52, and the adjusting ring 53 is used for rotating to control the height of the pressing ring 52; specifically, the outer surface of the pressing ring 52 is uniformly provided with a wedge-shaped groove 521, and the outer surface of the adjusting ring 53 is fixed with a pressing block 531 abutting against the wedge-shaped groove 521, and the pressing block 531 is used for pushing the wedge-shaped groove 521; for example, by rotating the adjusting ring 53, the height of the adjusting ring 53 remains unchanged, the pressing block 531 pushes the wedge-shaped groove 521, the height of the pressing ring 52 is changed, and the pressing ring 52 can change the pressure applied to the spring 201, thereby pushing the shearing shaft 2 to control the position of the shearing shaft 2.

[0058] Further, the embodiment controls the axial height of the shearing shaft 2 by controlling the pressure of the spring 201 on the shearing shaft 2, instead of directly controlling the axial height of the shearing shaft 2 by the compression ring 52, so as to ensure the flexibility of the shearing shaft 2 and increase the service life of the shearing shaft 2; for example, when there are impurities with high hardness, such as metal particles, in the magnetic flocculation, if the height of the shearing shaft 2 is directly controlled by the compression ring 52, the shearing shaft 2 cannot be passively axially slid, and the shearing shaft 2 needs to shear the metal particles with a fixed shearing force, which increases the wear of the shearing shaft 2, while in the embodiment, the shearing shaft 2 can be passively axially slid, and when the shearing shaft 21 and the fixed blade 31 shear the metal particles, if the shearing force is greater than the elastic force of the spring 201, the shearing shaft 2 can be axially slid towards the spring 201, avoiding hard shearing of the metal particles and reducing the wear of the shearing shaft 2.

[0059] Further, referring to Figure 5 As shown in the figure, the outer surface of the second fixed seat 51 is fixed with a distance adjusting motor 54, the output end of the distance adjusting motor 54 is fixed with a worm 541, and the worm 541 is rotationally connected with the second fixed seat 51; the outer surface of the worm 541 is engaged with a worm wheel 542, and the worm wheel 542 is coaxially fixedly connected with the adjusting ring 53; for example, the distance adjusting motor 54 in the embodiment can adopt a stepping motor or a servo motor, the distance adjusting motor 54 drives the worm 541 to rotate, the worm 541 can drive the worm wheel 542 to rotate, so that the worm wheel 542 drives the adjusting ring 53 to rotate, thereby controlling the height of the compression ring 52.
