Description

Technical Field

[0001] The present application relates to the field of filter press technology, and in particular to a high-pressure diaphragm filter press. Background Art

[0002] High-pressure diaphragm filter press is a solid-liquid separation equipment used for filtering various media, and the filter cake after filtration has low moisture content.

[0003] Some existing high-pressure diaphragm filter presses are mainly composed of a filter press mechanism, a collecting mechanism and a mud receiving bucket. When in use, sewage containing mud is discharged into the filter press mechanism, so that the sewage is filtered by the filter press mechanism, and the mud inside the sewage is retained in the filter press mechanism and pressed into a mud cake, while the water filtered by the filter press mechanism is discharged into the collecting mechanism. After that, the filter press mechanism is opened, so that the above-mentioned mud cake falls into the mud receiving bucket and waits for subsequent collection and processing. Through the above actions, the sewage filtration operation is completed.

[0004] However, in the above process, due to the low moisture content of the mud cake and the large volume of the mud cake, the mud cake is easy to block the outlet of the mud receiving bucket, thereby affecting the subsequent collection and processing of the mud cake. Utility Model Content

[0005] The present application proposes a high-pressure diaphragm filter press, which has the advantage of reducing the volume of the mud cake, and is used to solve the problem that the mud cake blocks the outlet of the mud receiving bucket, thereby affecting the subsequent collection and processing operations of the mud cake.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a high-pressure diaphragm filter press, comprising: a mounting member, a filter press mechanism is arranged at the upper position of the inner side of the mounting member, a mud receiving bucket is fixedly installed at the inner side of the mounting member and at the lower side of the filter press mechanism, the inlet of the mud receiving bucket faces the filter press mechanism, the outlet of the mud receiving bucket faces away from the filter press mechanism, and a collecting mechanism is arranged between the filter press mechanism and the mud receiving bucket;

[0007] An opening and closing valve is arranged at the outlet of the mud receiving bucket and is used to open and close the outlet of the mud receiving bucket;

[0008] A rotating shaft is rotatably installed at the middle and upper side of the inner cavity of the mud receiving bucket, a power motor is fixedly installed on one side of the mud receiving bucket and at the position corresponding to the rotating shaft, one end of the rotating shaft facing the power motor is fixedly connected to the output end of the power motor, and contact knives are equidistantly fixed axially on the circumferential side of the rotating shaft, and there is a distance between the end of the contact knife facing the mud receiving bucket and the inner wall of the mud receiving bucket.

[0009] Furthermore, a turntable is sealed and rotatably installed in the wall body on the front and rear sides of the mud receiving bucket and at the position located at the mud receiving bucket outlet, and a shift shaft is fixedly installed on the opposite sides of the two turntables. A transmission mechanism is provided on one side of the mud receiving bucket, and the transmission mechanism connects the turntable and the rotating shaft to achieve synchronous movement of the turntable and the rotating shaft.

[0010] Furthermore, the transmission mechanism includes a driving gear, a passive gear, a transmission wheel and a transmission belt. A driving gear is arranged on the side of the mud receiving bucket facing away from the power motor, and one end of the rotating shaft facing away from the power motor is fixed to the center position of the driving gear. A passive gear is rotatably installed on the side of the mud receiving bucket facing away from the power motor and located at the lower side of the driving gear. The driving gear and the passive gear form a meshing connection. Transmission wheels are fixed on the side of the passive gear facing away from the power motor and on the side of the turntable corresponding to the passive gear facing away from the power motor, and transmission belts are connected to the outer sides of the two transmission wheels.

[0011] Furthermore, the diameter of the driving gear is greater than the diameter of the driven gear.

[0012] This application has the following beneficial effects:

[0013] The present application provides a high-pressure diaphragm filter press, which, through the arrangement of a rotating shaft and a contact knife, utilizes rotation to drive the contact knife to swing back and forth in a mud receiving bucket, thereby contacting and breaking the mud cake, thereby reducing the volume of the mud cake, thereby reducing the probability of the mud cake clogging the mud receiving bucket outlet, making the subsequent collection and processing of the mud cake less likely to be affected.

[0014] By setting up the turntable and the shifting shaft, the shifting shaft is driven to rotate at the outlet of the mud receiving bucket by rotation, thereby applying a shifting force to the mud cake blocked at this position, so that the mud cake at this position constantly changes its position, thereby further reducing the probability of the mud cake blocking the outlet of the mud receiving bucket, making the subsequent collection and processing operations of the mud cake less likely to be affected.

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

[0022] See also Figure 1 and Figure 2 A high-pressure diaphragm filter press comprises a mounting member 1, a filter press mechanism 2 (existing technology) is arranged at the upper position of the inner side of the mounting member 1, a mud receiving bucket 3 is fixedly installed at the inner side of the mounting member 1 and at the lower side of the filter press mechanism 2, the inlet of the mud receiving bucket 3 faces the filter press mechanism 2, the outlet of the mud receiving bucket 3 faces away from the filter press mechanism 2, a collecting mechanism (existing technology, not shown in the figure) is arranged between the filter press mechanism 2 and the mud receiving bucket 3, and an opening and closing valve 4 (such as the electric oil cylinder and the sealing valve in the prior art) is arranged at the outlet of the mud receiving bucket 3 A combination of a closing plate and a closing plate is used to open and close the outlet of the mud receiving bucket 3. A rotating shaft 5 is rotatably installed at the middle and upper side of the inner cavity of the mud receiving bucket 3. A power motor 6 (such as a forward and reverse motor in the prior art) is fixedly installed on one side of the mud receiving bucket 3 and at a position corresponding to the rotating shaft 5. The rotating shaft 5 extends out of the mud receiving bucket 3 toward one end of the power motor 6 and is fixedly connected to the output end of the power motor 6. Contact knives 7 are axially equidistantly welded on the circumferential side of the rotating shaft 5, and there is a distance between the end of the contact knife 7 facing the mud receiving bucket 3 and the inner wall of the mud receiving bucket 3.

[0023] When in use, sewage containing mud is discharged into the filter press mechanism 2, so that the sewage is filtered by the filter press mechanism 2, and finally the mud is retained in the filter press mechanism 2 and is pressed into a mud cake, and the water filtered by the filter press mechanism 2 is discharged to the collecting mechanism, and then the filter press mechanism 2 is opened, so that the above-mentioned mud cake naturally falls into the mud receiving bucket 3, and then, when the mud cake needs to be processed, the opening and closing valve 4 is opened, so that the mud cake is discharged from the outlet of the mud receiving bucket 3, and at the same time, the power motor 6 drives the rotating shaft 5 to perform reciprocating incomplete rotation (such as half-circle reciprocating swing), so that the contact knife 7 swings back and forth in the mud receiving bucket 3, and then contacts and breaks the mud cake, so that the volume of the mud cake is reduced, thereby The probability of mud cake blocking the outlet of mud receiving bucket 3 is reduced. In addition, during the reciprocating swing of contact knife 7, mud cake in the swinging direction of contact knife 7 will be blocked by contact knife 7, while mud cake in the direction opposite to the swinging direction of contact knife 7 will be guided by contact knife 7, so that when the mud cake in mud receiving bucket 3 is discharged, the amount of mud cake discharged in the swinging direction of contact knife 7 is less than the amount of mud cake discharged in the direction opposite to the swinging direction of contact knife 7. Through this action, the impact forces of mud cakes discharged from both sides at the outlet of mud receiving bucket 3 are different (due to the different impact forces, mud cakes discharged from both sides are not easy to stagnate at the outlet of mud receiving bucket 3), thereby reducing the probability of mud cake blocking the outlet of mud receiving bucket 3.

[0024] See also Figure 1-Figure 3 , a turntable 8 is sealed and rotatably installed in the wall body on the front and rear sides of the mud receiving bucket 3 and at the position located at the outlet of the mud receiving bucket 3, and a dial shaft 9 is fixedly installed on the opposite sides of the two turntables 8. A driving gear 10 is arranged on the side of the mud receiving bucket 3 facing away from the power motor 6, and one end of the rotating shaft 5 facing away from the power motor 6 extends out of the mud receiving bucket 3 and is welded and fixed to the center position of the driving gear 10. A passive gear 11 is rotatably installed on the side of the mud receiving bucket 3 facing away from the power motor 6 and located at the lower side of the driving gear 10. The driving gear 10 is meshed with the passive gear 11. A transmission wheel 12 is welded on the side of the passive gear 11 facing away from the power motor 6 and the side of the turntable 8 corresponding to the passive gear 11 facing away from the power motor 6, and a transmission belt 13 is connected to the outer sides of the two transmission wheels 12.

[0025] In the process that the power motor 6 drives the rotating shaft 5 to perform incomplete reciprocating rotation (such as half-circle reciprocating swing), the rotating shaft 5 drives the driving gear 10 to move synchronously, so that the passive gear 11 drives the turntable 8 and the shifting shaft 9 to reciprocate through the transmission wheel 12 and the transmission belt 13. Since the shifting shaft 9 is located at the outlet of the mud receiving bucket 3, a shifting force is applied to the mud cake blocked at this position, so that the mud cake at this position constantly changes its position, thereby further reducing the probability of the mud cake blocking the outlet of the mud receiving bucket 3, so that the subsequent collection and processing of the mud cake is not easily affected.

[0026] See also Figure 1-Figure 3 , the diameter of the driving gear 10 is greater than the diameter of the driven gear 11.

[0027] By setting the above structure, the driving gear 10 and the passive gear 11 form a speed-increasing gear structure, so that when the driving gear 10 is not fully rotated, the passive gear 11 can rotate to a greater extent, thereby allowing the shift shaft 9 to move a longer path and drive the mud cake to move further, thereby further reducing the probability of the mud cake blocking the outlet of the mud receiving bucket 3.

[0028] The above gear structure is for illustration only, and the specific number of gear teeth can be adjusted accordingly according to actual conditions.
