Description

Technical Field

[0001] The utility model relates to the technical field of plate and frame filter presses, in particular to a buffer mechanism for a propeller of a plate and frame filter press. Background Art

[0002] As the main component of the plate and frame filter press, the propeller is responsible for pushing the plate and frame to move after the plate and frame process is completed to clean the filter residue between the plates and frames.

[0003] Existing plate-and-frame filter presses use a support rod fixed to the frame to support the movement of the propeller. During use, the connection of the support rod is prone to deformation, tilting, and local damage. This can cause the propeller on one side to shift laterally during operation, resulting in the propeller being unable to engage the plate frame, causing the plate frame to tilt, resulting in damage to the plate frame and increasing operator operation time. To address this issue, an improved method for the filter press plate-and-frame propeller is proposed to address the above-mentioned drawbacks. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a propeller buffer mechanism which reduces propeller pressure and buffers the impact force when the propeller contacts a plate frame, thereby improving the safety and durability of the propeller.

[0005] The utility model is realized through the following technical scheme: a buffer mechanism of a plate and frame filter press propeller, including a propeller main body sliding on the support rod of the filter press, the buffer mechanism including two swing arms hinged at the bottom of the propeller main body, the two swing arms are distributed front and back along the sliding direction of the propeller main body and extend obliquely in directions away from each other, rollers are installed at one end of the two swing arms away from each other, a gas spring is hingedly installed between the roller and the propeller main body, an angle is formed between the gas spring and the swing arm, a bottom cross bar supported below the roller is fixedly connected to the filter press, and the bottom cross bar is parallel to and opposite to the support rod.

[0006] In this solution, the roller and its support member act on the bottom crossbar, providing support for the original thruster body, reducing pressure on the original support rod and ensuring smooth and stable sliding of the thruster. The gas spring cushions the instantaneous impact force when the thruster contacts the frame, improving the thruster's safety and durability.

[0007] As an optimization, the thruster body includes a sliding sleeve that slides onto the support rod. Two opposing clamping plates are fixed to the top of the sleeve, and a connecting seat is fixed to the bottom of the sleeve. One end of the swing arm and gas spring is hinged to the connecting seat. This optimization solution enables the sliding sleeve to slide along the support rod, with the two clamping plates clamping the plate frame, thereby driving the movement of the plate frame. The connecting seat is used to connect the swing arm and gas spring.

[0008] As an optimization, the other end of the swing arm and the gas spring is hinged to the roller through a first hinge shaft. The swing arm, gas spring and roller are hinged to optimize the structure, increase the gas spring buffer stroke, and make it more stable to use.

[0009] As an optimization, the distance between the two rollers is greater than the length of the propeller body. In this optimization solution, the distance between the two rollers is slightly greater than the length of the main body, which can greatly improve the longitudinal stability of the propeller.

[0010] As an optimization, the clamping plate is an arc-shaped plate. This optimization solution facilitates clamping of the plate frame through one end of the arc.

[0011] As an optimization, the roller is made of silicone material. The silicone material of this optimization solution has good elastic shock absorption effect.

[0012] As an optimization, the swing arm is made of aluminum alloy. The aluminum alloy material of this optimization solution reduces weight while having better strength.

[0013] The beneficial effects of this utility model are as follows: the roller and its supporting member act on the bottom crossbar, providing support for the original propeller body, reducing the pressure on the original support rod, and ensuring smooth and stable sliding of the propeller. The gas spring can buffer the instantaneous impact force when the propeller contacts the plate frame, improving the safety and durability of the propeller. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0018] like Figure 1As shown, a buffer mechanism of a plate and frame filter press propeller includes a propeller body 1 sliding on a support rod 6 of the filter press, and the buffer mechanism includes two swing arms 3 hinged at the bottom of the propeller body 1, and the two swing arms 3 are distributed front and back along the sliding direction of the propeller body 1 and extend obliquely in a direction away from each other. A roller 4 is installed at one end of the two swing arms 3 away from each other, and the spacing between the two rollers 4 is greater than the length of the propeller body 1. A gas spring 2 is hingedly installed between the roller 4 and the propeller body 1, and an angle is formed between the gas spring 2 and the swing arm 3. In this embodiment, the two gas springs 2 are located on the side away from each other of the two swing arms 3, and the angle range of the angle is 15°~45°.

[0019] Specifically, the thruster body 1 includes a sliding sleeve 11 that is slidably connected to the support rod 6. In this embodiment, the support rod and the sliding sleeve are both made of square tubes. The support rod 11 is fixed to the frame of the filter press, and the sliding sleeve 11 is sleeved on the support rod 6 and slides along the length of the support rod. Two opposing clamps 12 are fixed to the top of the sliding sleeve 11. The clamps 12 in this embodiment are 90° arc-shaped plates. A connecting seat 13 is fixed to the bottom of the sliding sleeve 11. One end of the swing arm 3 and the gas spring 2 is hinged to the connecting seat 13. The other end of the swing arm 3 and the gas spring 2 is hinged to the roller 4 through the first hinge shaft 9. The distance between the two rollers 4 is greater than the length of the sliding sleeve 11.

[0020] The connecting seat 13 described in this embodiment includes an upper hinge seat 131 and a lower hinge seat 132. The length of the upper hinge seat 131 is less than the length of the sliding sleeve 11 and greater than the length of the lower hinge seat 132. The upper hinge seat 131 is fixed to the bottom of the sliding sleeve 11, and the lower hinge seat 132 is fixed to the bottom of the upper hinge seat 131.

[0021] Specifically, the upper ends of the two swing arms 3 are hinged to the ends of the lower hinge seat 132 via the second hinge shaft 8. The upper ends of the two gas springs 2 are hinged to the ends of the upper hinge seat 131 via the third hinge shaft 7. The roller 4 is a bearing-type roller, with the first hinge shaft 9 fixedly connected to the bearing of the roller 4. The lower ends of the gas spring 2 and the swing arm 3 are both rotatably connected to the first hinge shaft 9.

[0022] The filter press is fixedly connected to a bottom cross bar 5 supported below the roller 4. The bottom cross bar 5 is parallel to and opposite to the support bar 6. In this embodiment, the bottom cross bar 5 is fixed to the frame of the filter press.

[0023] Preferably, the roller 4 is made of silicone material, and the swing arm 3 is made of aluminum alloy.

[0024] During use, the two clamping plates 12 of the propeller body 1 clamp the plate frame, and the buffer mechanism acts on the bottom crossbar 5 to provide support for the propeller body 11, reducing the pressure on the support rod 6 and ensuring smooth and stable sliding of the propeller. When the propeller starts and stops, it applies pressure to the rollers 4 at the front and rear ends. The gas spring 2 buffers this pressure to maintain stability, and the swing arms 3 on both sides provide balanced support.
