Description
Technical Field
[0001] The utility model belongs to the technical field of filter presses, and in particular relates to a filter press used for treating slag wastewater. Background Art
[0002] A filter press is a filtering device for solid-liquid separation. It uses a filter plate (or filter cloth) as a filtering medium and applies a certain pressure to the material to make the liquid seep out, thereby achieving the purpose of solid-liquid separation. Its working principle mainly includes the steps of mixture supply, filtering process, compression process and unloading process. During the filtering process, the liquid in the mixture enters the gap between the filter plates through the filter medium, while the solid is trapped on the surface of the medium. When the filtering is completed, the hydraulic system starts to work, and by applying a certain pressure, the filter plate is deformed, further squeezing the solid matter to reduce the water content, so as to achieve a higher separation effect.
[0003] In the prior art, when the filter press is working, the hydraulic cylinder usually moves the filter plates closer one by one, and finally squeezes the filter plates against each other, so that the filtering operation can be performed. After the operation is completed, the plate pulling trolley pulls the filter plates apart one by one, so that the filter residue between the two filter plates can fall down.
[0004] However, in the above operation process, the working time required for squeezing and pulling back the filter plates one by one is relatively long, which reduces the working efficiency of the filter press and is not conducive to production. Utility Model Content

[0008] Auxiliary cleaning mechanism, the number of the auxiliary cleaning mechanisms is one less than the number of filter press plates, and each of the auxiliary cleaning mechanisms is respectively arranged directly above the fitting surfaces of two adjacent filter press plates, the auxiliary cleaning mechanism comprises a mounting plate, a plurality of nozzles are symmetrically arranged at the bottom of the mounting plate, and the bottom of the nozzles is inclined downward and points to the side of the filter press plate, two connecting seats are symmetrically arranged at both ends of the mounting plate, the top of each connecting seat is respectively connected to the bottom of a connecting shaft, a connecting column is slidably installed in each connecting seat along the vertical direction, and the bottom of the connecting column is connected to one side of the mounting plate, and a lifting component for driving each connecting column to synchronously perform linear motion along the vertical direction is also arranged on the top plate.
[0009] According to a further technical solution, a first slide groove seat is also installed on the top plate, and the top of each installation shaft is slidably installed in the first slide groove seat.
[0010] According to a further technical solution, two groups of lifting assemblies are symmetrically arranged on the top of the top plate, and the lifting assemblies include a linear movable module installed on the top of the top plate, a second slide groove seat is installed at the telescopic end of the linear movable module, and each of the connecting columns located on the same side is slidably installed in the same second slide groove seat.

After the filtration process is completed, the hydraulic push rod shrinks and each filter press plate is separated from the state of contacting each other. At this time, it is only necessary to control the linear moving module to extend, and the linear moving module pushes each connecting column to move downward synchronously through the second slide seat.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] The connecting rod mechanism 3 comprises a mounting shaft 31, a first connecting rod 32 and a second connecting rod 33, and the length of the second connecting rod 33 is twice the length of the first connecting rod 32. A mounting shaft 31 is installed on the top of each filter press plate 21, and a first slide groove seat 35 is also installed on the top plate 11, and the top of each mounting shaft 31 is slidably installed in the first slide groove seat 35. For each mounting shaft 31, two first connecting rods 32 are symmetrically installed on the two mounting shafts 31 on both sides, and two second connecting rods 33 arranged in an X shape are installed on the remaining mounting shafts 31. The two ends of each second connecting rod 33 are rotatably connected to the second connecting rod 33 or the first connecting rod 32 on the adjacent mounting shaft 31 through a connecting shaft 34. During use, through the mutual cooperation of each first connecting rod 32 and the second connecting rod 33, each filter press plate 21 can be moved synchronously, and the spacing between two adjacent filter press plates 21 is always kept equal;
[0025] Auxiliary cleaning mechanism 4, the number of the auxiliary cleaning mechanism 4 is one less than the number of the filter press plates 21, and each of the auxiliary cleaning mechanisms 4 is respectively arranged directly above the fitting surfaces of two adjacent filter press plates 21, the auxiliary cleaning mechanism 4 includes a mounting plate 42, a plurality of nozzles 43 are symmetrically arranged at the bottom of the mounting plate 42, and the bottom of the nozzle 43 is inclined downward and points to the side of the filter press plate 21, two connecting seats 41 are symmetrically arranged at both ends of the mounting plate 42 (the mounting plate 42 is not directly connected to the connecting seat 41), the top of each connecting seat 41 is respectively connected to the bottom of a connecting shaft 34, and a connecting column 44 is slidably installed in each connecting seat 41 along the vertical direction, and at the same time, a connection seat 41 is also provided with a connection column 44 for the connecting column 44 to slide along the length direction of the mounting plate 42. The long through hole for linear sliding is used to match the distance change between the two symmetrical connecting shafts 34 at both ends along the length direction of the mounting plate 42. The bottom of the connecting column 44 is connected to one side of the mounting plate 42. The top plate 11 is also provided with a lifting component 5 for driving each connecting column 44 to synchronously perform linear movement along the vertical direction. In the process of synchronous opening of each filter press plate 21, under the action of the connecting rod mechanism 3, each group of auxiliary cleaning mechanisms 4 will always be located directly above the middle position of two adjacent filter press plates 21. When the filter residues on both sides of each filter press plate 21 are to be detached, the lifting component 5 can be used to drive each mounting plate 42 to move downward synchronously, so that the nozzle 43 at the bottom of the mounting plate 42 blows air from top to bottom to the side of the filter press plate 21, thereby accelerating the detachment of the filter residue.
[0026] As a preferred embodiment of the utility model, each of the mounting shafts 31 is installed on the top of the filter plate 21 by bolt connection.

[0027] like Figure 1 As shown, as a preferred embodiment of the utility model, two groups of lifting assemblies 5 are symmetrically arranged on the top of the top plate 11, and the lifting assembly 5 includes a linear movable module 52 installed on the top of the top plate 11, and the telescopic end of the linear movable module 52 is installed with a second slide groove seat 51, and each of the connecting columns 44 located on the same side is slidably installed in the same second slide groove seat 51.
[0028] In the embodiment of the utility model, the linear moving module 52 is a hydraulic telescopic rod. In the initial state, the linear moving module 52 is in a retracted state. At this time, during use, it is only necessary to control the linear moving module 52 to extend downward, and the linear moving module 52 can drive the second slide slot seat 51 to move downward synchronously, and the second slide slot seat 51 can synchronously push each connection column 44 to move downward, thereby driving the mounting plate 42 to move downward through the connecting column 44, so as to blow air from top to bottom to the side of the filter press plate 21 through the nozzle 43 at the bottom of the mounting plate 42. After the operation is completed, it is only necessary to control the linear moving module 52 to retract to the initial position, and then drive each connection seat 41 to rise synchronously to the initial position through the linear moving module 52, and then an operation process is completed.

[0030] Working principle: When in use, the hydraulic push rod 2 can push the filter press plate 21 connected thereto to slide in the horizontal direction. At the same time, through the mutual cooperation of each first connecting rod 32 and the second connecting rod 33, each filter press plate 21 can be moved synchronously, and the spacing between two adjacent filter press plates 21 is always kept equal, so that each filter press plate 21 can be quickly fitted together, and there will be no collision between the filter press plates 21 due to the excessive movement of the hydraulic push rod 2. When the filtration process is completed, the hydraulic push rod 2 shrinks and each filter press plate 21 is separated from the state of contacting each other. At this time, it is only necessary to control the linear moving module 52 to extend, and the linear moving module 52 pushes each connecting column 44 to move downward synchronously through the second slide seat 51. The connecting column 44 can drive the mounting plate 42 to move downward. At this time, the external air supply device can blow air from the top to the side of the filter press plate 21 through the nozzle 43 at the bottom of the mounting plate 42, thereby accelerating the separation of the filter residue attached to the filter press plate 21. After the operation is completed, it is only necessary to control the linear moving module 52 to retract to the initial position, and then drive each mounting plate 42 to rise to the initial position synchronously through the linear moving module 52, thereby completing one operation process.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
