Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm filter press accessories, in particular to a braking device for a diaphragm filter press. Background Art

[0002] Diaphragm filter presses are widely used in various fields that require solid-liquid separation. They are filter presses with an elastic membrane installed between the filter plate and the filter cloth. During use, when the feeding is completed, high-pressure fluid or gas medium can be injected into the diaphragm plate. At this time, the entire diaphragm will bulge and compress the filter cake, thereby achieving further dehydration of the filter cake. There are two parts of the diaphragm filter press that require braking devices when working. One is the shaft or motor used to drive the water tray switch, and the other is the unloading device that pushes the filter frame to separate, which is convenient for emergency stop operations and braking positioning during structural operation.

[0003] When the braking device is in use, the brake pads and brake discs are both consumable parts and will wear out after a period of use. Therefore, they need to be replaced regularly to avoid excessive structural wear and difficulty in braking. However, when replacing the brake pads and brake discs, it is necessary to first remove the housing and the bolts on the housing, and then remove the brake pads, brake discs and the bolts on the two. The installation operation is the opposite, which makes the replacement operation cumbersome and complicated. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a braking device for a diaphragm filter press to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a braking device for a diaphragm filter press, comprising a base, a hydraulic cylinder and a transmission shaft, the top of the base is connected to a movable shell through a fixed shell, and a limit plate is fixed inside the movable shell, a fastener is connected to the outer surface of the fixed shell, the output end of the hydraulic cylinder is connected to a mounting seat, and a brake pad is passed through one side of the mounting seat, and a sliding sleeve is sleeved on the outside of the transmission shaft.

[0006] By adopting the above technical scheme, the outer shell and cover plate of the brake device that were originally separated by bolts are improved into a fixed shell and a movable shell, which are limited by fasteners. The internal structure can be exposed by simply unfastening the fasteners and then rotating the movable shell to open, so as to facilitate quick replacement. After the movable shell is opened, the limit plate is away from the brake pad, thereby ending the limitation of the brake pad. Subsequently, the brake pad can be separated from the mounting seat by simply rotating the brake pad half a circle to complete the disassembly work. After that, a new brake pad is placed on the top of the mounting seat and the brake pad is rotated half a circle again, so that the brake pad can be installed in the mounting seat. The brake pad is limited by the mounting seat to prevent the brake pad from shifting up, down, left, and right in the mounting seat and falling off. After that, the movable shell is closed and limited by the fasteners. At this time, the limit plate is against the top of the brake pad to prevent the brake pad from rotating and falling off.

[0007] Furthermore, the movable shell is rotatably connected to the fixed shell via a hinge, and the fastener is detachably connected to the movable shell.

[0008] By adopting the above technical solution, the outer shell and cover plate of the brake device originally separated by bolts are improved into a fixed shell and a movable shell, which are limited by fasteners. The internal structure can be exposed by simply unfastening the fasteners and then rotating the movable shell to open it.

[0009] Furthermore, the mounting seat and the brake pad are both semicircular, and the brake pad is detachably connected to the mounting seat.

[0010] By adopting the above technical solution, after the movable shell is opened, the limit plate is away from the brake pad, thereby ending the limitation of the brake pad. Subsequently, the brake pad only needs to be rotated half a circle to separate the brake pad from the mounting seat to complete the disassembly work.

[0011] Furthermore, a protrusion with a "T"-shaped cross section is provided on one side of the brake pad, and a groove with a "T"-shaped cross section is provided on one side of the mounting seat.

[0012] By adopting the above technical solution, a new brake pad is placed on the top of the mounting seat and then the brake pad is rotated half a circle, so that the brake pad can be installed in the mounting seat. The brake pad is limited by the mounting seat to prevent the brake pad from shifting up and down, left and right and falling off in the mounting seat.

[0013] Furthermore, the brake pad abuts against the limiting plate.

[0014] By adopting the above technical solution, the movable shell is closed and limited by the fastener. At this time, the limit plate abuts against the top of the brake pad to prevent the brake pad from rotating and falling off.

[0015] Furthermore, the sliding sleeve is made of Teflon material, and a protrusion is arranged on the outer ring of the sliding sleeve.

[0016] By adopting the above technical solution, the sliding sleeve reduces the wear between the transmission shaft and the fixed shell and the movable shell when the transmission shaft rotates, and the protrusions on the outside of the sliding sleeve prevent the transmission shaft, the sliding sleeve and the brake pad from shifting left and right.

[0017] Furthermore, the transmission shaft is detachably connected to the fixed shell and the movable shell.

[0018] By adopting the above technical solution, the coupling between the drive shaft and the diaphragm filter press components is disassembled, and then the movable shell is opened to directly take out and replace the drive shaft, sleeve and brake pad. After the new drive shaft, sleeve and brake pad are placed in the fixed shell, the movable shell is closed to complete the limiting. At the same time, the sleeve reduces the wear between the drive shaft and the fixed shell and the movable shell when the drive shaft rotates, and the protrusion on the outside of the sleeve prevents the drive shaft, sleeve and brake pad from shifting left and right.

[0019] Furthermore, the hydraulic cylinder is installed on one side of the fixed shell, and the transmission shaft is arranged between the fixed shell and the movable shell, and a brake disc is fixed in the middle of the outer surface of the transmission shaft.

[0020] By adopting the above technical solution, the transmission shaft is connected to the movable parts of the diaphragm filter press through a coupling. When braking is required, the output end of the hydraulic cylinder pushes the mounting seat to move, so that the brake pad is close to the brake disc and fits with the brake disc. At this time, braking is performed through the friction between the brake pad and the brake disc. When braking is not required, the output end of the hydraulic cylinder pulls the mounting seat back, and the brake pad is away from the brake disc to end the braking operation.

[0021] Furthermore, a fan is installed on one side of the top of the base, and a ventilation pipe is connected between the fan and the fixed shell.

[0022] By adopting the above technical solution, air is blown into the fixed shell and the movable shell through the fan and the ventilation pipe, so as to reduce the heat generated by the friction between the brake pad and the brake disc, so as to extend the service life of the structure.

[0023] In summary, the utility model mainly has the following beneficial effects:

[0024] 1. The utility model improves the outer shell and cover plate of the brake device originally separated by bolts into a fixed shell and a movable shell through a fixed shell, a movable shell, a limiting plate, a mounting seat and a brake pad. The fixing is performed by fasteners. Only the fasteners need to be unfastened and the movable shell can be rotated to open to expose the internal structure, so as to facilitate quick replacement. After the movable shell is opened, the limiting plate is away from the brake pad, thereby ending the limiting of the brake pad. Subsequently, only the brake pad needs to be rotated half a circle to separate the brake pad from the mounting seat to complete the disassembly work. After that, a new brake pad is placed on the top of the mounting seat and the brake pad is rotated half a circle again to install the brake pad in the mounting seat. The brake pad is limited by the mounting seat to prevent the brake pad from deviating up and down and falling off in the mounting seat. After that, the movable shell is closed and limited by fasteners. At this time, the limiting plate abuts against the top of the brake pad to prevent the brake pad from rotating and falling off. It is convenient to replace the brake pad, and the operation is simple, convenient and labor-saving.

[0025] 2. The utility model disassembles the coupling between the transmission shaft and the diaphragm filter press components by setting the transmission shaft, the sliding sleeve and the brake disc. After that, the transmission shaft, the sliding sleeve and the brake pad can be directly taken out and replaced by opening the movable shell. After the new transmission shaft, the sliding sleeve and the brake pad are placed in the fixed shell, the movable shell is closed to complete the limiting. At the same time, the sliding sleeve reduces the wear between the transmission shaft and the fixed shell and the movable shell when the transmission shaft rotates, and the protrusion on the outside of the sliding sleeve prevents the transmission shaft, the sliding sleeve and the brake pad from shifting left and right, so it is convenient to replace the brake disc.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] The following describes an embodiment of the utility model based on its overall structure.

[0033] Embodiment 1:

[0034] A brake device for a membrane filter press, such as Figure 1-Figure 4As shown, it includes a base 1, a hydraulic cylinder 4 and a transmission shaft 5. The top of the base 1 is connected with a movable shell 3 through a fixed shell 2. The movable shell 3 is rotatably connected to the fixed shell 2 through a hinge. The internal structure can be exposed by simply unfastening the fastener 8 and then rotating and opening the movable shell 3; a limiting plate 9 is fixed inside the movable shell 3, and the brake pad 11 abuts against the limiting plate 9. The movable shell 3 is closed and limited by the fastener 8. At this time, the limiting plate 9 abuts against the top of the brake pad 11 to prevent the brake pad 11 from rotating and falling off; a fastener 8 is connected to the outer surface of the fixed shell 2, and the fastener 8 is detachably connected to the movable shell 3. The movable shell 3 is closed and limited by the fastener 8, which effectively prevents the movable shell 3 from rotating and opening at will; a mounting seat 10 is connected to the output end of the hydraulic cylinder 4, and a brake pad 11 passes through one side of the mounting seat 10. A protrusion with a "T"-shaped cross section is provided on one side of the brake pad 11, and a groove with a "T"-shaped cross section is provided on one side of the mounting seat 10. The mounting seat 10 and the brake pad 11 are both semicircular. The brake pad 11 and the mounting seat 10 is disassembled and connected, and the severely worn brake pad 11 is rotated half a circle, so that the severely worn brake pad 11 can be separated from the mounting seat 10 to complete the disassembly work. After that, the staff puts a new brake pad 11 on the top of the mounting seat 10 and rotates the brake pad 11 half a circle, so that the brake pad 11 can be installed in the mounting seat 10; the transmission shaft 5 is sleeved with a sliding sleeve 12 on the outside, and the sliding sleeve 12 is made of Teflon material. The outer ring of the sliding sleeve 12 is provided with a protrusion, and the sliding sleeve 12 reduces the wear between the transmission shaft 5 and the fixed shell 2 and the movable shell 3 when the rotation, and the protrusion outside the sliding sleeve 12 prevents the transmission shaft 5, the sliding sleeve 12 and the brake pad 11 from shifting left and right; the transmission shaft 5 is disassembled and connected with the fixed shell 2 and the movable shell 3, and the coupling between the transmission shaft 5 and the diaphragm filter press components is disassembled, and then the staff can directly take out the transmission shaft 5, the sliding sleeve 12 and the severely worn brake pad 11 together for replacement, and put the new transmission shaft 5, the sliding sleeve 12 and the brake pad 11 into the fixed shell 2.

[0035] See also Figure 1 , Figure 2 and Figure 4 In the above embodiment, the hydraulic cylinder 4 is installed on one side of the fixed shell 2, the transmission shaft 5 is arranged between the fixed shell 2 and the movable shell 3, and a brake disc 13 is fixed in the middle of the outer surface of the transmission shaft 5. The output end of the hydraulic cylinder 4 pushes the mounting seat 10 to move, so that the brake pad 11 is close to the brake disc 13 and fits with the brake disc 13. At this time, braking is performed by the friction between the brake pad 11 and the brake disc 13.

[0036] Embodiment 2:

[0037] On the basis of the above-mentioned first embodiment, in order to reduce the heat generated by the friction between the brake pad 11 and the brake disc 13 during braking, the following settings are now adopted to facilitate heat dissipation and thereby extend the service life of the structure.

[0038] See also Figure 1 and Figure 2 In the above embodiment, a fan 6 is installed on one side of the top of the base 1, and a ventilation pipe 7 is connected between the fan 6 and the fixed shell 2. The fan 6 cooperates with the ventilation pipe 7 to blow air into the fixed shell 2 and the movable shell 3 to reduce the heat generated by the friction between the brake pad 11 and the brake disc 13, so as to extend the service life of the structure.

[0039] The implementation principle of the utility model is as follows: first, the transmission shaft 5 is connected to the movable part of the diaphragm filter press through a coupling. When braking is required, the output end of the hydraulic cylinder 4 pushes the mounting seat 10 to move, so that the brake pad 11 is close to the brake disc 13 and fits the brake disc 13. At this time, braking is performed by the friction between the brake pad 11 and the brake disc 13. At the same time, the fan 6 can cooperate with the ventilation pipe 7 to blow air into the fixed shell 2 and the movable shell 3 to reduce the heat generated by the friction between the brake pad 11 and the brake disc 13, so as to extend the service life of the structure. When braking is not required, the output end of the hydraulic cylinder 4 pulls the mounting seat 10 back, and at this time, the brake pad 11 is away from the brake disc 13 to end the braking operation;

[0040] When the brake pad 11 and the brake disc 13 need to be replaced, the staff only needs to unfasten the fastener 8 and then rotate and open the movable shell 3 to expose the internal structure. After the movable shell 3 is opened, the limiting plate 9 is away from the brake pad 11, thereby ending the limiting of the brake pad 11;

[0041] The staff rotates the severely worn brake pad 11 half a circle, so that the severely worn brake pad 11 can be separated from the mounting seat 10 to complete the disassembly work. After that, the staff places a new brake pad 11 on the top of the mounting seat 10 and rotates the brake pad 11 half a circle, so that the brake pad 11 can be installed in the mounting seat 10. The brake pad 11 is limited by the mounting seat 10 to prevent the brake pad 11 from deviating up and down or left and right in the mounting seat 10 and falling off;

[0042] At the same time, the staff disassembles the coupling between the transmission shaft 5 and the diaphragm filter press components, and then the staff can directly take out and replace the transmission shaft 5, the sliding sleeve 12 and the severely worn brake pad 11, and put the new transmission shaft 5, the sliding sleeve 12 and the brake pad 11 into the fixed shell 2;

[0043] Afterwards, the staff closes the movable shell 3 and limits it through the fastener 8. At this time, the limit plate 9 is against the top of the brake pad 11 to prevent the brake pad 11 from rotating and falling off. At the same time, the sliding sleeve 12 reduces the wear between the fixed shell 2 and the movable shell 3 when the transmission shaft 5 rotates, and the protrusion outside the sliding sleeve 12 prevents the transmission shaft 5, the sliding sleeve 12 and the brake pad 11 from shifting left and right.

[0044] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
