Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a filter press vibration unloading mechanism. Background Technology

[0002] A filter press is a traditional solid-liquid separation device, mainly used for filtration, dewatering, or extracting filtrate. A filter press consists of multiple filter plates and frames stacked together to form a filter chamber, using pressure as the driving force for filtration. Filter presses operate intermittently and are classified into three types: plate and frame filter presses, chamber filter presses, and vertical filter presses. They are widely used in various industries, including chemical, environmental protection, and food processing.

[0003] Vibration in a filter press refers to the process of vibrating the filter cake after filtration is completed in a filter press, using a vibrating device to help the filter cake fall off the filter cloth, so as to facilitate subsequent unloading operations.

[0004] Currently, the rapping system uses a sequential single-rapping method, where each filter plate is moved, then lifted by a rapping cylinder and quickly retracted, using the instantaneous impact force to remove the filter cake from the plate. Although this method has a good rapping effect, the rapping process is time-consuming due to the large number of filter plates to be processed in the filter press.

[0005] Therefore, improvements are proposed. Utility Model Content

[0006] This utility model is a filter press vibration unloading mechanism proposed to overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a filter press vibration unloading mechanism, comprising a filter press body and a plurality of filter plates installed on the filter press body, wherein slide rails are fixedly connected to both sides of the outer surface of the filter press body frame, and a horizontal lifting steel is slidably connected between two slide rails on the same side; electric cam assemblies are fixedly installed on both sides of the filter press body, and the electric cam assemblies are matched with the horizontal lifting steel.

[0008] The tops of the two horizontal lifting steels are fixedly connected to fixed seats, the two fixed seats are equipped with electric lifting components, and the two electric lifting components are connected to the adjacent fixed seats with a scissor-type telescopic frame, and the bottom of the scissor-type telescopic frame is in contact with the top of the horizontal lifting steel.

[0009] Lifting seats are fixedly connected to both sides of the outer surface of multiple filter plates, and multiple lifting seats are fixedly connected to the pins at the adjacent hinge points at the bottom of the scissor-type telescopic frame.

[0010] Each of the lifting seats has a sliding assembly on one side of its outer surface, and the sliding assembly is connected to the adjacent scissor-type telescopic frame.

[0011] Furthermore, both of the electric cam assemblies include a mounting base, which is fixedly mounted on one outer wall of the filter press body frame. A drive motor is fixedly mounted on one side of the outer surface of the mounting base. A cam is fixedly connected to the drive end of the drive motor, and the mounting shaft of the cam is rotatably connected to the frame of the filter press body. By rotating the cam, the horizontal lifting steel can be raised and lowered.

[0012] Furthermore, both of the electric lifting components include a stepper motor, which is fixedly mounted on the top of the fixed base. The drive end of the stepper motor is fixedly connected to a lead screw, which passes through the fixed base and is rotatably connected to it. The outer surface of the lead screw is threaded with a slide block, which slides against the inner walls on both sides of the fixed base and is rotatably connected to the scissor-type telescopic frame, facilitating the expansion or contraction of the scissor-type telescopic frame.

[0013] Furthermore, a connecting seat is fixedly connected to one side of the outer surface of each of the two fixed seats, and the connecting seat is rotatably connected to the scissor-type telescopic frame. The connecting seat enhances the structural strength between the scissor-type telescopic frame and the fixed seat.

[0014] Furthermore, each of the sliding components includes a sliding groove, which is formed on the outer surface of the lifting seat. A round rod is slidably connected in the sliding groove, and the round rod is fixedly connected to a pin at the adjacent hinge at the top of the scissor-type telescopic frame. The round rod and the sliding groove cooperate to ensure that the lifting seat is stably deployed under the action of the scissor-type telescopic frame.

[0015] Furthermore, both drive motors and stepper motors are electrically connected to the built-in controller of the filter press body. By uniformly controlling the drive motors and stepper motors through the controller, the automated operation of the filter plate unfolding, lifting, vibrating and resetting can be realized, reducing manual intervention.

[0016] The beneficial effects of this utility model are:

[0017] In use, this utility model discloses a filter press vibration unloading mechanism. An electric cam assembly drives the horizontally positioned lifting steel to move synchronously up and down. This, combined with the linkage between the scissor-type telescopic frame and the electric lifting assembly, enables the synchronous unfolding and unified lifting and vibration of multiple filter plates. This design overcomes the time-consuming drawback of traditional single-plate sequential vibration. By utilizing the rapid descent characteristic of the cam, an instantaneous impact force is applied to all filter plates, significantly shortening the unloading time while ensuring the vibration effect.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4As shown, a vibrating unloading mechanism for a filter press is disclosed, comprising a filter press body 1 and multiple filter plates 5 mounted on the filter press body 1. Slide rails 2 are fixedly connected to both sides of the outer surface of the filter press body 1 frame. A horizontal lifting steel 6 is slidably connected between two slide rails 2 on the same side. Electric cam assemblies are fixedly mounted on both sides of the filter press body 1, and the electric cam assemblies are matched with the horizontal lifting steel 6. Each electric cam assembly includes a mounting base 3, which is fixedly mounted on one side of the outer wall of the filter press body 1 frame. A drive motor 4 is fixedly mounted on one side of the outer surface of the mounting base 3. A cam 8 is fixedly connected to the drive end of the drive motor 4, and the mounting shaft of the cam 8 is rotatably connected to the frame of the filter press body 1. The mounting shaft of the cam 8 is fixedly connected to the frame of the filter press body 1 through a bearing seat. The inner ring of the bearing in the bearing seat is fixedly connected to the mounting shaft, and the seat body of the bearing seat is fixedly connected to the frame, providing support for the cam 8 and reducing the rotational friction of the cam 8.

[0027] Both horizontal lifting steel bars 6 are fixedly connected to their tops with fixed seats 7. Each fixed seat 7 is equipped with an electric lifting assembly. A scissor-type telescopic frame 12 is installed between each electric lifting assembly and the adjacent fixed seat 7. The bottom of the scissor-type telescopic frame 12 is in contact with the top of the horizontal lifting steel bars 6. The scissor-type telescopic frame 12 is a mechanical structure connected by multiple connecting rods and pins. Both electric lifting assemblies include a stepper motor 13, which is fixedly installed on the top of the fixed seat 7. A lead screw 1 is fixedly connected to the drive end of the stepper motor 13. 5. The lead screw 15 passes through the fixed base 7 and is rotatably connected to the fixed base 7. The outer surface of the lead screw 15 is threaded with a slide 14, and the slide 14 slides against the inner walls on both sides of the fixed base 7 and is rotatably connected to the scissor-type telescopic frame 12. The scissor-type telescopic frame 12 and the slide 14 are rotatably connected by a pin. One side of the outer surface of each of the two fixed bases 7 is fixedly connected with a connecting seat 16, and the connecting seat 16 is rotatably connected to the scissor-type telescopic frame 12. The connecting seat 16 and the scissor-type telescopic frame 12 are rotatably connected by a pin.

[0028] Multiple filter plates 5 have lifting seats 9 fixedly connected to both sides of their outer surfaces, and multiple lifting seats 9 are fixedly connected to the pins at the adjacent hinge points at the bottom of the scissor-type telescopic frame 12.

[0029] Each of the multiple lifting seats 9 has a sliding component on one side of its outer surface, and the sliding component is connected to the adjacent scissor-type telescopic frame 12. Each of the multiple sliding components includes a slide groove 11, and the slide groove 11 is opened on the outer surface of the lifting seat 9. A round rod 10 is slidably connected in the slide groove 11, and the round rod 10 is fixedly connected to the pin at the adjacent hinge at the top of the scissor-type telescopic frame 12.

[0030] Both drive motors 4 and stepper motor 13 are electrically connected to the built-in controller of the filter press body 1, which facilitates the control of the overall operation. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in combination with common knowledge.

[0031] Working principle: After the filter press completes filtration, the built-in controller starts the stepper motor 13, which drives the lead screw 15 to rotate, causing the slide 14 to slide along the inner wall of the fixed seat 7.

[0032] The movement of the slide block 14 pushes the scissor-type telescopic frame 12 to unfold. Since the lifting seats 9 of multiple filter plates 5 are all fixed to the hinge points at the bottom of the scissor frame, all filter plates 5 are pulled open synchronously to form a uniform gap, which facilitates subsequent vibration unloading.

[0033] After the filter plate 5 is fully extended, the controller starts the drive motors 4 on both sides, which drive the cam 8 to rotate.

[0034] The protruding part of the cam 8 pushes the horizontal lifting steel 6 to move upward along the slide rail 2. Since the horizontal lifting steel 6 is connected to the scissor telescopic frame 12 through the fixed seat 7, the bottom of the scissor telescopic frame 12 is in contact with the top of the horizontal lifting steel 6, so all the filter plates 5 are lifted synchronously.

[0035] When cam 8 rotates to its highest point and continues to rotate, the horizontally placed lifting steel 6 falls instantly under the action of gravity, causing all the filter plates 5 to fall rapidly. The instantaneous impact force generated during the fall causes the filter cake to detach from the filter cloth due to inertia, achieving efficient unloading.

[0036] After the vibration is completed, the stepper motor 13 reverses and the scissor-type telescopic frame 12 retracts, causing the filter plate 5 to close again, ready to enter the next filtration cycle.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
