Description

Sludge crusher and crushing method using same

The present invention relates to the field of sludge drying, and to a crusher for crushing a sludge block in a sludge drying process, and more specifically, a vertical crusher and a sludge block using the same It relates to a crushing method.

In the sludge drying process, it is usually necessary to dewater the liquid sludge to turn the liquid sludge into a solid sludge. The dewatering treatment usually separates the liquid from the solids in the sludge with a solid-liquid separation device, and the dewatered sludge forms larger blocks with a predetermined moisture content. To facilitate subsequent burying, solidifying or drying treatment of the sludge block, it is necessary to break the larger sludge block into smaller ones. Compared with other solid-liquid separation equipment, the filter press can produce sludge blocks with higher solids content, with a moisture content of about 75% to 40%, and the sludge blocks have high hardness and It is characterized by non-fragility.

Conventional crushing machines include a jaw crusher, a gyratory crusher, a cone crusher, a hammer crusher, a roller crusher, a vibration crusher, etc. , but is not limited thereto. These crushing machines turn larger sludge blocks into smaller ones by applying crushing components to the sludge blocks to improve the flow of the sludge, which is advantageous for transport and subsequent treatment of the sludge. However, these crushing machines have several disadvantages, one of them is that during crushing of the sludge, the sludge block clogs the machine, and the size of the smaller crushed blocks is not uniform, so that the crushing machine does not work continuously and the sludge The stability of the crushing may be affected, increasing the difficulty of subsequent processing, especially of lowering the moisture content of smaller crushed blocks in the drying process. Therefore, it is desirable to provide a sludge block crusher and crushing method that ensure a stable crushing process and uniform particle size.

In order to solve this problem, the present invention provides a vertical sludge crusher (vertical sludge crusher). The vertically disposed housing of the vertical sludge crusher has one or more crushing assemblies. The shredding assembly includes a rotatable assembly disposed on top of the other and a stationary assembly, wherein the rotatable assembly is positioned above the stationary assembly. By rotating the rotatable assembly relative to the stationary assembly, the sludge block can be broken into smaller sludge blocks or fragments having a uniform particle size in a way that increases the flowability of the smaller sludge blocks or fragments. and uniformly dry the smaller blocks or fragments in the subsequent drying process before the process of making the sludge block into powder.

In the vertical sludge crusher of the present invention, the rotatable assembly includes a rotating shaft and one or more rotating arms installed on the rotating shaft. An upper end of the rotating shaft is rotatably located in a shaft hole in a top cover of the housing, and the rotating arm is configured to move the rotating arm from a lower end of the rotating shaft to the housing. one or more fracturing elements extending at an angle towards the sidewall and projecting downward; The stationary assembly includes a stationary seat having a central post and at least one supporting rod, and at least one annular piece. Each of the one or more support rods extends at an angle toward a side wall of the housing, one end is fixed to the central post and the other end is connected to the side wall of the housing, the one end being connected to the side wall of the housing. Each of the at least one annular member is fixed to the at least one support rod at a predetermined interval in the longitudinal direction of the support rod around the central post. The rotatable shaft of the rotation assembly has an axis parallel to the axis of the central post of the stationary assembly, wherein the one or more crushing elements of the one or more rotation arms and the one or more annular members secured to the one or more support rods alternately disposed such that the one or more crushing elements move circumferentially along a corresponding one of the one or more annular members when the rotatable assembly rotates relative to the stationary assembly, each crushing element comprising two adjacent annular members It corresponds to the space between the members.

In the vertical sludge crusher of the present invention, discontinuous protrusions are arranged on the top surface of the annular member of the holding assembly so that the bearing surface for receiving the sludge block of the holding assembly is uneven. . Recesses formed between adjacent protrusions may impede the circumferential motion of the sludge block with rotation of the rotatable assembly, and may also hold the sludge block, resulting in breaking or shearing of the sludge block ( By facilitating shearing, the deposition of the sludge block in the housing is reduced.

In the vertical sludge crusher of the present invention, the elements constituting the crushing assembly can be separated, so that the rotatable assembly and the fixed assembly and the components or elements thereof are formed according to the moisture content of the sludge block and the size of the crushed or sheared sludge block. It is selected and replaced according to wear of the associated components, thereby facilitating and flexible engagement of the crushing assembly.

In the vertical sludge crusher of the present invention, a housing having a different cross-sectional shape may be used if necessary, and the feeding inlet of the sludge block is at the top or side of the housing above the crushing assembly. formed in position, making the allocation between the shredder and the associated equipment convenient and space-efficient.

In the vertical sludge crusher of the present invention, the crushing assembly for crushing the sludge block is capable of crushing or shearing smaller sludge blocks or fragments of uniform size by a predetermined spacing between the plurality of annular members of the fixed assembly. The spacing between the plurality of annular members can not only prevent circumferential movement of the sludge block with rotation of the rotatable assembly, but also act as a measurer of crushed or sheared smaller sludge blocks or fragments, so that the spacing By allowing only smaller sludge blocks or fragments to pass through, it is possible to crush or shear the sludge blocks according to a predetermined size.

In addition, the present invention provides a method of crushing the sludge block with a vertical crusher. The dewatered sludge block is conveyed into the housing from the top or upper side of the housing of the shredder, and the rotation of the rotatable assembly, relative to the stationary assembly of the shredding assembly, causes a rotating arm on the rotating shaft of the rotatable assembly to rotate the sludge block and crusher. By impacting the elements to cut or shear the sludge block, it is possible to obtain smaller sludge blocks or fragments with a uniform particle size. The smaller sludge blocks or fragments then fall through the gap between the annular members of the holding assembly and drain out of the housing through an opening in the lower portion of the housing.

The crushing assembly and crushing method for crushing the sludge block of the present invention can control the particle size of the crushed sludge block. The components or elements of the shredding assembly of the present invention are selected and combined to obtain smaller sludge blocks or fragments having a uniform particle size within the expected range. Due to the reduction of the sludge particle size, it is possible not only to increase the flowability of smaller sludge blocks, but also to accelerate the drying rate of the sludge drying process, thereby improving the drying efficiency. This is advantageous in terms of improving the porosity of the dried sludge and facilitating subsequent sludge treatment.

2 to 4 and 6 , the fixing assembly 31 includes a fixing seat 310 and an annular member 313 . The fixed seat 310 has a central post 311 and one or more support rods 312 extending outwardly from the central post 311 at a certain angle, the support rods 312 being centrally located. It preferably extends outwardly from the post 311 at right angles. For example, around the central post 311 there are two to ten support rods 312 spaced at a particular angle. One or more annular members 313 are positioned on the support rods 312 , preferably on the two or more support rods 312 to stabilize the positioning of the annular member 313 . For example, there are 2 to 8 annular members 313 arranged at predetermined intervals in the longitudinal direction of the support rod 312 or in the radial direction of the housing 2 , and each annular member 313 has a ring (ring). ) or an arc segment, the radius of the ring or arc segment being related to its position on the support rod 312 . That is, the closer to the central post 311, the smaller the radius of the ring or arc segment. 3 and 6 show four annular members or rings 313 each disposed at predetermined intervals on four support rods 312 .

As shown, the upper end 301A of the rotating shaft 301 of the rotatable assembly 30 is rotatably disposed in a shaft hole 204 for receiving the rotating shaft 301 and is a top cover of the housing 2 . A power input piece 4 , such as a gear or pulley, is provided on a portion of the upper end 301A formed in 201 and extending outwardly of the shaft hole 204 . . The power input member 4 may be connected to a drive device by a belt or chain to drive the rotating shaft 301 . Each of the support rods 312 of the fixing assembly 31 has one end connected to the central post 311 and the other end adjacent to the lowermost opening of the housing 2 installed in, for example, an orifice 205 formed in the wall. is connected to Of course, it can also be fixed directly to the side wall in a known connection manner. In FIG. 4 , the four support rods 312 each extend at right angles to the central post 311 , and the two rotary arms 302 project radially in opposite directions with respect to the rotary shaft 301 . To stabilize the fixing seat 310 of the fixing assembly 31 , the fixing assembly 31 has three or more support rods that are usually spaced at the same angle and also extend outward from the outer surface of the central post 311 . 312 is disposed, and two or more annular members 313 may be disposed on the support rod 312 at equal or different intervals. In other words, adjacent ring or arc segments may be spaced at different distances along the support rod 312 , with the ring or arc segment being farther to the central post 311 than adjacent ring or arc segments with smaller radii than larger ones. Closer, each ring or arc segment is stably positioned on two or more support rods 312 , so that two annular members 313 adjacent in the longitudinal direction of the support rods 312 or in the radial direction of the housing 2 are may be maintained at a predetermined interval. The crushing element 303 of the rotating arm 302 of the rotatable assembly 30 may project downwardly into a corresponding space between adjacent annular members 313, such that the plurality of crushing elements 303 and the plurality of annular members ( The 313 may be alternately disposed, so that when the rotating shaft 301 rotates, the crushing element 303 may move circumferentially in a corresponding space along the inner or outer periphery of the annular member 313 . To facilitate stabilization of the rotating shaft 301 , the plurality of rotating arms 302 are usually arranged symmetrically with respect to the rotating shaft 301 . As shown, the two rotary arms 302 are symmetrically arranged at an angle of 180°, have four downwardly projecting crushing elements or cutting blades 303 in the longitudinal direction of the rotary arm 302, and three crushing Elements or cutting blades 303 are each located in a corresponding space formed between two adjacent annular members 313 .

Referring to FIG. 3 , since the housing 2 is positioned vertically, ie at right angles to the ground, the rotating shaft 301 of the rotatable assembly 30 is of the central post 311 of the stationary assembly 31 . substantially coincident with the axis, and the axes of the rotating shaft 301 and the central post 311 are substantially parallel to the longitudinal axis of the housing 2 , preferably the rotating shaft 301 and the central post 311 . The axis of is coincident with the longitudinal axis of the housing (2). The rotating arm 302 and the support rod 312 are parallel and close to each other. Since the crushing elements 303 and the annular members 313 are alternately arranged, the crushing elements 303 of the rotary arm 302 are respectively corresponding to between two adjacent annular members 313 on the support rod 312 . The width of the crushing element 303 in the longitudinal direction of the rotary arm 302 or in the radial direction of the housing 2 may extend into the space, and the width of the crushing element 303 between the two annular members 313 on the support rod 312 is corresponding to that between the two annular members 313 on the support rod 312. smaller than space. In other words, the spacing between two adjacent crushing elements 303 is greater than the width of the corresponding annular member 312 on the support rod 312 in the longitudinal direction of the support rod 312 , so that the support member 30 is When rotating relative to the fixing assembly 31 , each crushing element 303 is always positioned within a corresponding space between two adjacent annular members 312 so that the crushing element 303 does not interfere with the annular member 313 . make sure not to

3 and 4 , among the plurality of annular members 313 of the anchoring assembly 31 , each annular member 313 may have one or more spaced apart protrusions 314 , each having one or more spaced apart protrusions 314 . Alternatively, the discontinuous projections 314 are fixed to the upper surface of the annular member 313 in a known connection manner, and the projections 314 in the longitudinal direction of the support rod 312 or in the radial direction of the annular member 313 . ) may be equal to or smaller than the width of the annular member 313 . These protrusions 314 and the annular member 314 may be integrally formed. These projections 314 increase the thickness of some areas of the annular member 313 in the axial direction of the central post 311 . That is, the height of the annular member 313 is increased at some positions in the longitudinal axis direction of the housing 2 . As described above, during the shredding process, the rotatable assembly 30 rotates relative to the stationary assembly 31 , and the sludge blocks entering the crusher fall substantially onto the stationary assembly 31 . Accordingly, a discontinuous or incomplete surface made up of the upper surfaces of the plurality of annular members 313 of the fixing assembly 31 becomes a bearing surface for accommodating the sludge block. Since the protrusion 314 of the annular member 313 makes the bearing surface uneven, the sludge block falling on the annular member 313, which is smaller than the spacing between the annular members 313, is at the bottom of the housing 2 of the crusher. Most of the sludge blocks that will be discharged from the opening, larger than that gap, are sandwiched between the projections 314 so that only a portion of them can move circumferentially with the rotating arm 302 of the rotatable assembly 30 . Accordingly, these projections 314 on the annular member 313 prevent the sludge block falling onto the annular member 313 from rotating with the rotating arm 302 , such that the majority of the sludge block moves on the stationary assembly 31 . to facilitate the crushing or shearing of the sludge block by the crushing element 303 of the rotary arm 302 .

2 and 3 , the fracturing element 303 in the corresponding space between adjacent annular members 313 during rotation of the rotatable assembly 30 may affect the operation of the fracturing element 303 . In order to align the rotation shaft 301 of the rotatable assembly 30 with the central post 311 of the stationary assembly 31 to prevent bending, a blind hole or A shaft hole 315, which may be a through hole, is formed. At the lower end of the rotating shaft 301, a shaft end 301B having a different diameter is formed, and since the diameter of the shaft end 301B and the diameter of the rotating shaft 301 are different, the shoulder ( shoulder) is formed. Since the diameter of the shaft end 301B corresponds to the inner diameter of the shaft hole 315 of the central post 311 , the shaft end 301B of the rotary shaft 301 is rotatably located within the shaft hole 315 , and the rotary shaft The end face of the shoulder of 301 may contact the top surface of the central post 311 . This arrangement of the rotating shaft 301 and the central post 311 achieves centering between the rotating shaft 301 and the central post 311 as well as the rotation of the rotating shaft 301 by the central post 311 . guarantee support. The shaft hole 204 in the closed end of the housing 2 or in the top cover 201 and the shaft hole 315 of the central post 311 of the fixing assembly 31 are, respectively, of the rotating shaft 301 . It accommodates the upper end 301A and the lower end 301B, which ensures the relative stability of the crushing element 3 and simplifies its structure.

In another embodiment, the structures of the rotating shaft and the central post are interchangeable, for example, a blind hole is formed in the end face of the lower end 301B of the rotating shaft 301 while the central post 311 is formed. A short shaft is formed on the upper end face of the short shaft, and the diameter of the short shaft corresponds to the inner diameter of the blind hole in the rotation shaft, and the short shaft is rotatably positioned in the blind hole, and the lower end ( The cross section of 301B contacts the top surface of the central post 311 , so that rotation of the rotation shaft 301 with respect to the central post 111 is made.

In a further embodiment, under circumstances in which the axis of the rotational shaft 301 of the rotatable assembly 30 substantially coincides with the axis of the central post 311 of the stationary assembly 31, the rotational shaft 301 may 311) and can be separated. That is, although the lower end of the rotating shaft 301 is spaced a predetermined distance from the upper end of the central post 311 , the crushing element may still be located within a corresponding space between adjacent annular members 313 .

In a further embodiment, the protrusion on the upper surface of the annular member 313 may be eliminated so that the bearing surface for receiving the sludge block is a discontinuous or incompletely flat surface. A portion of the sludge block will move in the circumferential direction with the rotating arm 302 of the rotatable assembly 30, but the efficiency of crushing the sludge block with small particle size can be improved.

In a further embodiment, one of the central post 311 of the fixed assembly 31 and the rotating shaft 301 of the rotatable assembly 30 is adjustable relative to the other as needed, so that the The distance between the rotating arm 302 and the support rod 312 or the annular member 313 of the stationary assembly 31 can be adjusted, and furthermore, the fracturing extending into a corresponding space between two adjacent annular members 313 . The length of element 303 can be adjusted.

In the crushing assembly 3 , the width of the crushing element 303 in the axial direction of the housing 2 is substantially smaller than the spacing between adjacent annular members, such that the greater between the crushing element 303 and the annular member 313 . Because gaps exist, a thinner cutting blade can replace the fracturing element, for example to enhance shearing or cutting effects. The size of the gap may depend on the desired sludge block, for example a smaller gap may be used when shearing a harder block of sludge, and the fracturing element 303 may be a pointed element. When shearing a softer block of sludge, larger gaps can be used. In other embodiments, the front end and/or rear end of the fracturing element 303 may be formed with tip(s) in the circumferential direction of rotation such that the rotating shaft rotates clockwise or counterclockwise. Regardless, the fracturing element 303 is capable of shearing the sludge block.

The crushing assembly 3 of the crusher 1 of the present invention is disposed adjacent the bottom opening of the housing 2 to help crush the sludge block. Discontinuous projections 314 of the annular member 313 of the fixing assembly 31 when the sludge block falls by its own gravity from the feed port 203 at the top of the housing 2 onto the crushing assembly 3 at the bottom. not only facilitates crushing of falling sludge blocks but also tends to keep the sludge blocks immobile on the annular member 313 . The sludge block falling on the bearing surface of the annular member 313 is crushed due to the collision of the rotating arm 302 driven by the rotating shaft 301, and the sludge block caught in the gap between the annular member 313 is a crushing element As the 303 moves in the circumferential direction it may be cut or sheared into sludge fragments or smaller blocks, after which the sludge fragments or smaller blocks pass through the gap through the shredder through the bottom opening of the housing 2 (1) It is discharged outside. Also, since the crushing assembly 3 is located adjacent to the lowermost opening of the housing 2 , the distance between the crushing assembly 3 and the feed port 203 is increased, i.e. to accommodate the sludge block in the housing 2 . The space for making the sludge block is large enough to adjust the amount of the sludge block injected into the housing 2 as needed to control the crushing speed of the sludge block, and the sludge block subsequently supplied into the housing 2 is the gravity of the sludge block. can apply a force to the already supplied sludge block in the housing 2 to move it toward the crushing assembly 3, thereby accelerating the crushing speed of the sludge block, and also saving the supply power for pushing the material.

7 shows an improved form of the housing of the sludge crusher in a partially cut-away perspective view. As shown, the housing 2' includes a top cover 201' and a cylinder 202', an upper portion of the cylinder 202' having a rectangular cross-section, and a lower portion thereof. ) has a circular cross-section, and the shape of the top cover 201' coincides with the cross-sectional shape of the upper part of the cylinder 202' so as to surround the upper opening of the cylinder 202'. A shaft hole 204' is formed in the center of the uppermost cover 201', and a bearing is provided therein so that, for example, the rotation shaft 301 of the rotatable assembly 30 of the crushing assembly 3 can be installed. can be A supply port 203' for receiving the sludge block is formed on the side wall of the upper part of the cylinder 202', and instead of the top, the sludge block is transported from the outside through the side into the crusher 1 do. The feed port 203 ′ may be formed at any location on the sidewall higher than the crushing assembly 3 . The cross-sectional shape of the cylinder 202' may be of any suitable shape, such as circular, oval, square, rectangular or trapezoidal. Alternatively, like the cylinder 202', a portion of the housing 2' has one cross-sectional shape and another portion has a different cross-sectional shape, or the cylinder 202' has a plurality of segments with different cross-sectional shapes. . Preferably, the portion of the housing 2' on which the crushing assembly 3 is provided has a circular cross-sectional shape, which facilitates the rotation of the rotatable assembly 30 disposed within the housing 2' to sludge the sludge. Not only does it effectively crush the block, but it also facilitates the placement of the circular member 313 on the support rod 312 of the fixing assembly 31 so that the unbroken sludge block is transferred to the wall of the housing 2' and the annular member 313. to prevent falling through the gaps between them. Correspondingly, the shape of the top cover 201' may coincide with the upper opening of the cylinder 202'. Further, in order to fix the support rod 313 to the housing 2', a plurality of holes 205' corresponding to the support rod 312 of the fixing assembly 31 are provided in the side wall of the cylinder 201' adjacent to the lowermost opening. ) can be formed.

Although the specific structure of a preferred embodiment of the vertical crusher for crushing the sludge block of the present invention has been described above, those skilled in the art can see that the crusher of the present invention may have other modifications and arrangements. As described above, the rotating arms, crushing elements, support rods and annular members of different materials or shapes may be selected according to the moisture content or hardness of the sludge block. The crushing assembly may be disposed at other locations within the housing other than a location adjacent to the bottom of the housing, and one or more crushing assemblies may be disposed as needed. For example, two vertically spaced shredding assemblies may be disposed within a vertically disposed housing, wherein the upper shredding assembly primarily crushes a larger block of sludge blocks entering the housing, while the lower shredding assembly , called secondary shredding, further shredding of smaller blocks, allowing multi-stage cutting or shearing of sludge blocks to be achieved to obtain smaller blocks or fragments as desired.

The drive device of the rotatable assembly may be any suitable power device including, but not limited to, an electric motor, a hydraulic actuating device, a pneumatic device, and the like. Any other suitable transmission method may be used between the drive device and the rotating shaft, including, but not limited to, pulleys and belts, sprockets and chains, gear drives, and the like for power transmission.

8 shows a flow chart of a preferred embodiment of the crushing of sludge blocks by means of a vertical crusher. The process of crushing the sludge of the present invention can be performed as follows: by driving a power input element of the upper end 301A of the rotating shaft 301 by a driving device to drive the fixed assembly 31 rotate the rotating body 30; conveying the sludge block into the housing (2) of the crusher (1) through a supply port for receiving the sludge block formed on the top (201) or sidewall (202) of the housing (2); When the sludge block enters into the housing 2 and falls continuously on the stationary assembly 31 , the sludge block is impinged by the rotating arm 302 of the rotatable assembly 30 , and the sludge block is impinged by the crushing element 303 . After the block is cut, sheared or crushed, smaller sludge blocks or fragments sheared smaller than the spacing between the annular members are discharged from the lowermost opening of the housing (2). Since the position of the annular member of the anchoring assembly on the support rod is predetermined, i.e. the gap between the annular members or the gap between the crushing member and the annular member is predetermined according to the desired size of the smaller sludge block or fragment, The spacing between adjacent annular members and the size and number of protrusions on the annular member can be predetermined according to the desired size of the smaller sludge block, and the shape and size of the crushing member can be preselected according to the moisture content of the sludge block. In addition, the speed of transporting the sludge block through the supply port can be adjusted according to the moisture content of the sludge block, for example, the transport speed of the sludge block with a high moisture content can be reduced, while the transport speed of the sludge block with a low moisture content can be reduced. The transport speed can be increased.

The crusher of the present invention is vertically arranged to save area occupied, and the sludge block is conveyed into the crusher through the feed port at the top of the housing to transport or push the sludge block forward by the own weight of the sludge block, which saves energy and increase efficiency. The crushing assembly of the vertical crusher of the present invention can be suitably configured according to the moisture content of the sludge block to be crushed, for example, a person skilled in the art can select the number of rotary arms, crushing elements, support rods and annular members as needed. can determine the spacing between the annular members, and the shape and size of the crushing element and the protrusion. A person skilled in the art can partially or individually replace the components of the shredding assembly, depending on the degree of wear. Thus, one skilled in the art can flexibly configure or combine the components of the crushing assembly, such as the rotating arm, crushing element, support rod and annular member, depending on the moisture content of the sludge block to be crushed, thereby allowing for smaller sludge blocks or fragments as desired. can get By using the crushing method performed by the vertical crusher of the present invention, the crushing assembly can be maintained in good operating condition by controlling the feeding rate of the sludge block or the amount of the supplied sludge block to adjust the crushing speed. The protrusion disposed on the annular member can fix most of the sludge block within the housing of the crusher, increasing the crushing efficiency.
