Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a filter plate protection structure for filter presses. Background Art

[0002] The filtering mechanism is composed of filter plates, filter frames, filter cloths, and squeezed diaphragms. The filter plates are covered with filter cloths on both sides. When squeezed diaphragms are required, a set of filter plates is composed of diaphragm plates and side plates. The base plates of the diaphragm plates are covered with rubber diaphragms on both sides, and the outside of the diaphragms are covered with filter cloths. The side plates are ordinary filter plates.

[0003] When using a filter press to filter liquid, it is necessary to press several groups of filter plates tightly. At this time, collision and extrusion will occur between the filter plates. When the filter press is used too frequently, the filter plates are easily damaged by impact. At the same time, when using the filter press, if the feed speed is too fast or the feed volume is too large, it may cause excessive pressure between two adjacent groups of filter plates, causing deformation or cracking, resulting in poor filtering effect between the filter plates and affecting the service life of the filter plates. Therefore, a filter plate protection structure for a filter press is proposed. Utility Model Content

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a filter plate protection structure for a filter press.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filter plate protection structure for a filter press, comprising a filter plate body, and also comprising:

[0006] A buffer assembly is provided on the filter press plate body to prevent the filter press plate body from being damaged by pressure;

[0007] Wherein, the buffer assembly includes a fixed frame, which is installed on the outer side of the filter press plate body, a movable frame is sleeved on the front side of the filter press plate body, a damping rod is installed on the outer side of the filter press plate body, a lifting rod is sleeved inside the damping rod, and a connecting piece is connected to the end of the lifting rod, a first slot is opened inside the fixed frame, a shock-absorbing spring is sleeved on the outer surface of the lifting rod, an extrusion piece is installed on one side of the movable frame, a sealing strip is installed on the inner wall of the movable frame, and a second slot is opened on the front side of the filter press plate body.

[0008] As mentioned above, the shock absorbing spring is located at the inner side of the first notch, and the shock absorbing spring is elastically supported between the first notch and the connecting member.

[0009] As mentioned above, the outer sides of the extrusion piece and the connection piece are both provided with chamfers, and the chamfers of the extrusion piece are in extrusion contact with the chamfers of the connection piece.

[0010] As mentioned above, the sealing strip is sleeved with the second notch, and rubber is bonded to the extrusion surface of the sealing strip and the second notch.

[0011] As mentioned above, when the movable frame is squeezed, the surface of the movable frame can be flush with the surface of the filter press plate body.

[0012] Compared with the prior art, the filter plate protection structure for the filter press has the following beneficial effects:

[0013] 1. The utility model cooperates between the movable frame and the filter press plate body. After the movable frame is subjected to pressure, it will slide along the outer surface of the filter press plate body. At the same time, through the cooperation between the extrusion member and the connecting member, when the extrusion member squeezes the connecting member, a pressure will be applied to the lifting and contraction rod through the connecting member. At this time, the shock-absorbing spring will offset the pressure on the connecting member, causing the lifting and contraction rod to shrink toward the inside of the damping rod, so that the vibration energy generated can be absorbed, weakened and dispersed through the damping rod, thereby reducing the stress and fatigue of the filter press plate body and extending their service life.

[0014] 2. The utility model cooperates between the sealing strip and the second notch. When the movable frame receives pressure, the sealing strip will be sleeved on the outside of the second notch. At this time, the surface of the movable frame can be flush with the surface of the filter press plate body. When several groups of filter press plate bodies are pressed tightly, two groups of filter press plate bodies can fit together without affecting their use effect. At the same time, due to the rubber arranged on the surface of the sealing strip, it has a buffering effect when it is impacted, and has good sealing performance to prevent leakage.

[0015] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and will be apparent to those skilled in the art based on the following examination and study, or may be taught from the practice of the present invention to some extent.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4 As shown, the utility model provides a filter plate protection structure for a filter press, comprising a filter plate body 1, and also comprising:

[0023] A buffer assembly is arranged on the filter press plate body 1 to prevent the filter press plate body 1 from being damaged by pressure;

[0024] Among them, the buffer assembly includes a fixed frame 2, which is installed on the outside of the filter press plate body 1, a movable frame 3 is sleeved on the front of the filter press plate body 1, a damping rod 4 is installed on the outside of the filter press plate body 1, a lifting rod 5 is sleeved inside the damping rod 4, and a connecting piece 7 is connected to the end of the lifting rod 5. A first slot 6 is opened inside the fixed frame 2, and a shock-absorbing spring 8 is sleeved on the outer surface of the lifting rod 5. An extrusion piece 9 is installed on one side of the movable frame 3, a sealing strip 10 is installed on the inner wall of the movable frame 3, and a second slot 11 is opened on the front of the filter press plate body 1.

[0025] Through the cooperation between the movable frame 3 and the filter press plate body 1, after the movable frame 3 is subjected to pressure, it will slide along the outer surface of the filter press plate body 1. At the same time, through the cooperation between the extrusion member 9 and the connecting member 7, when the extrusion member 9 squeezes the connecting member 7, a pressure will be applied to the lifting and retracting rod 5 through the connecting member 7. At this time, the shock-absorbing spring 8 will offset the pressure exerted on the connecting member 7 and make the lifting and retracting rod 5 shrink toward the inside of the damping rod 4, so that the vibration energy generated can be absorbed, weakened and dispersed through the damping rod 4, thereby reducing the stress and fatigue of the filter press plate body 1 and extending their service life.

[0026] like Figure 3 As shown, the shock absorbing spring 8 is located at the inner side of the first notch 6 , and the shock absorbing spring 8 is elastically supported between the first notch 6 and the connecting member 7 .

[0027] The design of the shock-absorbing spring 8 allows the connector 7 to have good elastic restoring performance. At this time, since the shock-absorbing spring 8 is in a compressed state, an elastic force is applied to the connector 7, thereby buffering the pressure on the connector 7.

[0028] like Figure 2 As shown, chamfers are arranged on the outer sides of the extrusion piece 9 and the connection piece 7 , and the chamfers of the extrusion piece 9 are in extrusion contact with the chamfers of the connection piece 7 .

[0029] By setting the chamfers on the outer sides of the extrusion member 9 and the connecting member 7, when the extrusion member 9 squeezes the connecting member 7, the telescopic rod 5 will be driven to retract into the inside of the damping rod 4 through the connecting member 7, so that the pressure received can be absorbed by the damping rod 4 and the elastic force released by the shock-absorbing spring 8 can be offset.

[0030] like Figure 1 , 4 As shown, the sealing strip 10 is sleeved with the second notch 11 , and rubber is bonded to the extrusion surfaces of the sealing strip 10 and the second notch 11 .

[0031] Through the cooperation between the sealing strip 10 and the second notch 11, when the movable frame 3 is subjected to pressure, the sealing strip 10 will be sleeved on the outside of the second notch 11. At the same time, due to the rubber arranged on the surface of the sealing strip 10, it has a buffering effect when it is squeezed and has good sealing properties to prevent leakage.

[0032] like Figure 1 , 4 As shown, when the movable frame 3 is squeezed, the surface of the movable frame 3 can be flush with the surface of the filter press plate body 1.

[0033] Through the design of the movable frame 3, since the surface of the movable frame 3 can be flush with the surface of the filter press plate body 1, when several groups of filter press plate bodies 1 are pressed tightly, two groups of filter press plate bodies 1 can fit together, which can protect the filter press plate bodies 1 without affecting their use effect.

[0034] Working principle:

[0035] When the filter press is working, several groups of filter plate bodies 1 will be squeezed to make two adjacent groups of filter plate bodies 1 fit together. At this time, the movable frame 3 will be squeezed against the back side of another group of filter plate bodies 1. After the movable frame 3 is subjected to pressure, it will slide along the outer surface of the filter plate body 1. At the same time, through the cooperation between the extrusion member 9 and the connecting member 7, when the extrusion member 9 squeezes the connecting member 7, the lifting and shrinking rod 5 will be driven to move through the connecting member 7. At this time, the shock-absorbing spring 8 will offset the pressure on the connecting member 7, and at the same time, the lifting and shrinking rod 5 will shrink toward the inside of the damping rod 4, so that the vibration energy generated can be absorbed, weakened and dispersed through the damping rod 4, thereby reducing the stress on the filter plate body 1 and extending its service life.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
