Description

Technical Field

[0001] This utility model relates to the technical field of mud-closing devices, and in particular to a mud-closing device for a filter press. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device, and a sludge distribution device is used when using a filter press.

[0003] In the prior art, patent document CN218339164U discloses a mud-distributing device for a filter press, including a base plate, two side plates fixedly connected to the upper surface of the base plate, a top plate fixedly connected to the upper surface of each of the two side plates, a mixing box fixedly connected to the upper surface of the two top plates, a cover plate fixedly connected to the upper surface of the mixing box, a through hole on each side of the mixing box, and a bearing fixedly connected to the inner surface of each of the two through holes.

[0004] During use, it was found that the sludge from the above device fell directly onto the filter belt through the guide plate. The filter belt was subjected to a large impact from the sludge, resulting in poor uniformity of sludge distribution, which affected subsequent processing. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a mud-spreading device for a filter press.

[0006] This utility model discloses a sludge distribution device for a filter press, comprising a frame, a drive motor, conveying rollers, and a filter belt. Two sets of conveying rollers and multiple sets of auxiliary rollers are rotatably arranged inside the frame, with the auxiliary rollers positioned between the two sets of conveying rollers. A drive motor is mounted on the frame, with its output connected to one end of one set of conveying rollers. The filter belt is fitted around the outside of the two sets of conveying rollers. The device also includes a sludge distribution assembly and a dispersion assembly. The sludge distribution assembly is mounted on the frame, and the dispersion assemblies are installed at the top of the frame. In use, starting the drive motor causes the two sets of conveying rollers, in conjunction with the multiple sets of auxiliary rollers, to rotate the filter belt counterclockwise. The sludge is then distributed onto the filter belt from left to right via the sludge distribution assembly, reducing the inertial impact of the sludge on the filter belt and improving the uniformity of the sludge distribution.

[0007] Preferably, the sludge distribution assembly includes a support plate, a shell, a sludge inlet pipe, a flat sludge outlet pipe, a baffle plate, and a mixing assembly. The support plate is mounted on the top of the frame, and the shell is mounted on the top of the support plate. The sludge inlet pipe is located at the left end of the shell, and the flat sludge outlet pipe is obliquely positioned at the right end of the shell. The baffle plate is mounted on the frame on the right side of the shell, with its bottom end pressed against the top of the support plate. The mixing assembly is located inside the shell. The sludge pump, driven by a motor, transports sludge into the shell through the sludge inlet pipe. The mixing assembly is then activated, breaking up larger sludge lumps. As the sludge accumulates in the shell, the sludge at the top of the shell is spread evenly onto the filter belt from left to right through the flat sludge outlet pipe. When the sludge is spread evenly on the filter belt, it continues to spread to the right side of the filter belt due to inertia. The baffle plate limits the sludge to the right. Afterward, when the sludge on the filter belt passes under the support plate, the support plate limits the height of the sludge on the filter belt for a second spreading operation, improving spreading efficiency and extending the service life of the filter belt.

[0008] Preferably, the mixing assembly includes a second motor, a rotating shaft, and mixing and crushing rods. The rotating shaft is rotatably mounted inside the housing, and multiple sets of mixing and crushing rods are mounted on the rotating shaft inside the housing. The second motor is mounted on the housing, and the output end of the second motor is connected to one end of the rotating shaft. When the second motor is started, the rotating shaft drives the multiple sets of mixing and crushing rods to rotate rapidly inside the housing, thereby breaking up larger sludge lumps in the sludge and improving the subsequent filtration efficiency.

[0009] Preferably, the dispersing component includes side plates, strip openings, a top plate, bolts, and rakes. Two sets of side plates are provided at the top of the frame, each set of side plates has two sets of strip openings, and each set of bolts passes through each strip opening. Each set of bolts is threaded into the side plate. Multiple sets of rakes are provided at the bottom of the top plate. The multiple sets of rakes at the bottom of adjacent sets of top plates are crisscrossed. The height of the top plate is adjusted according to the filtration requirements, and then the bolts are rotated to fix the top plate. The multiple sets of rakes at the bottom of each set of top plates loosen the sludge on the filter belt, improving the uniformity of sludge distribution.

[0010] Preferably, it also includes a sealing cap and a No. 2 bolt. The top of the housing is provided with an inspection port, and the sealing cap seals the inspection port with the No. 2 bolt. When it is necessary to inspect the inside of the housing, the staff can loosen the No. 2 bolt, thereby releasing the sealing cap from sealing the inspection port, improving convenience.

[0011] Preferably, it also includes a handle, with a handle provided at the top of the sealing cover; the operator can move the sealing cover by using the handle, improving convenience.

[0012] Preferably, the handle is fitted with a handle cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the drive motor is started so that the two sets of conveying rollers, together with the cooperation of multiple sets of auxiliary rollers, drive the filter belt to rotate counterclockwise. The sludge is laid on the filter belt from left to right through the sludge spreading assembly, which reduces the inertial impact of the sludge on the filter belt and improves the uniformity of the sludge spreading.

This causes the stirring and crushing rods 11 to crush larger sludge lumps. As the sludge accumulates in the housing 5, the sludge at the top of the housing 5 is spread evenly on the filter belt 20 from left to right through the flat sludge outlet pipe 7. When the sludge is spread evenly on the filter belt 20, it will continue to spread to the right side of the filter belt 20 due to inertia. The baffle plate 8 limits the sludge to the right side. Afterwards, when the sludge on the filter belt 20 passes under the support plate 4, the support plate 4 limits the height of the sludge on the filter belt 20 for a second spreading operation, improving spreading efficiency and extending the service life of the filter belt 20.

[0030] In this embodiment, the sludge pump, via drive motor 2 and sludge inlet pipe 6, transports sludge into the housing 5. Starting motor 9 causes shaft 10 to drive multiple sets of stirring and crushing rods 11 to rotate rapidly inside the housing 5. This causes the stirring and crushing rods 11 to break up larger sludge lumps. As the sludge accumulates in the housing 5, the sludge at the top of the housing 5 is spread evenly on the filter belt 20 from left to right through flat sludge outlet pipe 7. When the sludge is spread evenly on the filter belt 20, it will, under the action of inertia,... Continue spreading the sludge to the right side of the filter belt 20.
