Description

Technical Field

[0001] The utility model relates to the technical field of buffer devices, and more specifically, to a buffer device for a liquid filtration device. Background Art

[0002] A liquid filtration device is a device used to remove suspended solid particles, microorganisms, or other impurities in a liquid. These devices are widely used in multiple industries, such as food and beverage processing, pharmaceuticals, chemistry, oil and gas, water treatment, and the electronics industry, and are also widely used in the filtration of liquid materials, such as filtering mud containing solid substances.

[0003] When adding the liquid to be filtered into the filtration device, the large-flow slurry will impact the surface of the screen, affecting the use of the screen and also its service life. Therefore, a liquid buffer structure is provided at the discharge port of the pipeline. For example, the Chinese patent with the application number 202321953642.4 discloses a sampling port fluid buffer, the structure of which includes a buffer container, the buffer container is provided with a buffer chamber, a fluid inlet, and a fluid outlet. The fluid inlet and the fluid outlet are both communicated with the buffer chamber. At least one baffle component is arranged in the buffer chamber, the baffle component is located on the flow path of the fluid, and a throttling structure is arranged in the buffer chamber, and the throttling structure is communicated with the fluid inlet. This sampling port fluid buffer has the function of buffering the liquid, but when the liquid flows on the baffle component, it will impact the baffle component, causing the overall structure to vibrate and also increasing the generation of noise.

[0004] Therefore, it is necessary to propose a buffer device for a liquid filtration device to solve the above problems. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides a buffer device for a liquid filtration device, which has the function of reducing the impact force of the liquid slurry, and at the same time, can reduce the vibration of the overall structure by compressing the spring.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A buffer device for a liquid filtration device includes a collar sleeved on the pipeline through a hose clamp. A buffer bottom cone and a material receiving hopper are arranged at the bottom of the collar. The buffer bottom cone is arranged inside the material receiving hopper. The buffer bottom cone, the material receiving hopper, and the pipeline are coaxially arranged. The bottom of the inner ring surface of the collar is connected with a guide rod penetrating the buffer bottom cone. A bottom plate is arranged at the bottom of the guide rod. A nut is arranged at the bottom of the bottom plate and is threadedly connected to the bottom of the guide rod. A spring is arranged between the buffer bottom cone and the bottom plate.

[0008] The outer ring surface of the collar is slidably connected up and down with a moving block. The top of the material receiving hopper is connected to the outer ring surface of the moving block. Upper and lower limit plates connected to the outer wall of the collar are arranged at the upper and lower ends of the moving block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. A buffer bottom cone is arranged at the bottom of the discharge pipeline of the device.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , a buffer device for a liquid filtering device, including a collar 101 sleeved on a pipeline through a hose clamp. A buffer bottom cone 102 and a material receiving hopper 103 are arranged at the bottom of the collar 101. The buffer bottom cone 102 is located at the bottom of the discharge pipeline. When the slurry comes out of the pipeline, it will impact on the buffer bottom cone 102 and spread around, thereby reducing the impact force of the slurry. A plurality of fixing strips are arranged at the top of the collar 101. When using the hose clamp to fix the collar 101, the hose clamp will not only contact the outer ring surface of the collar 101, but also contact the outer wall of the pipeline, which can increase the fixing ability of the collar 101 on the pipeline. The buffer bottom cone 102 is arranged inside the material receiving hopper 103. The buffer bottom cone 102, the material receiving hopper 103 and the pipeline are coaxially arranged. The distance between the buffer bottom cone 102 and the pipeline is adjusted through the hose clamp, thereby controlling the discharge speed of the slurry. The bottom of the inner ring surface of the collar 101 is connected with a guide rod 104 penetrating through the buffer bottom cone 102. The guide rod 104 has a guiding function, so that the buffer bottom cone 102 can only move up and down. A bottom plate 105 is arranged at the bottom of the guide rod 104. A nut 106 threadedly connected to the bottom of the guide rod 104 is arranged at the bottom of the bottom plate 105. A spring 107 is arranged between the buffer bottom cone 102 and the bottom plate 105. The buffer bottom cone 102 is arranged on the bottom plate 105 through the spring 107. When receiving an impact force, the impact force is slowed down through the compression of the spring 107, avoiding the situation of overall shaking;

[0025] A water guide plate 108 is connected to the top of the buffer bottom cone 102. When the slurry passes through the water guide plate 108, it will flow from both sides, and the water flow will not directly contact the guide rod 104, avoiding the situation where the slurry impacts the guide rod 104. The water guide plate 108 is sleeved on the outer wall of the guide rod 104, and a slope is provided on the side of the water guide plate 108 facing the axis of the buffer bottom cone 102;

[0026] A moving block 109 is slidably connected to the outer ring surface of the collar 101 up and down. The spring 107 pushes the moving block 109 against the bottom of the upper limit plate 110. When the slurry spreads out from the buffer bottom cone 102, most of the impact has been absorbed by the buffer bottom cone 102, but there will still be some impact force hitting the receiving hopper 103. The receiving hopper 103 absorbs the impact through the compression of the spring 107. The top of the receiving hopper 103 is connected to the outer ring surface of the moving block 109. Upper limit plates 110 and lower limit plates 111 connected to the outer wall of the collar 101 are provided at the upper and lower ends of the moving block 109. The upper limit plate 110 and the lower limit plate 111 play a role in limiting the moving block 109, and a spring 107 is provided between the moving block 109 and the lower limit plate 111;

[0027] The receiving hopper 103 is divided into a receiving part 112 and an inclined part 113. The bottom of the receiving part 112 converges towards the middle for converging the dispersed slurry towards the central position. The receiving part 112 is located at the bottom of the inclined part 113.

[0028] Specifically, a fixing plate 114 is connected to the top of the outer wall of the guide rod 104. The fixing plate 114 is used to limit the position of the buffer bottom cone 102 to prevent the buffer bottom cone 102 from being blocked at the discharge port of the pipeline due to the action of the spring 107. A buffer pad is connected to the bottom of the fixing plate 114, and the water guide plate 108 is located at the bottom of the buffer pad.

[0029] Specifically, a buffer pad is connected to the bottom of the upper limit plate 110. The buffer pad plays a buffering role to prevent the moving block 109 or the buffer bottom cone 102 from hitting the upper limit plate 110 or the fixing plate 114 due to the action of the spring 107 when the slurry supply stops, reducing the generation of noise. The moving block 109 is located at the bottom of the buffer pad.

[0030] In this embodiment, the collar 101 is fixed to the bottom of the feeding pipeline by a hose clamp. When the slurry is discharged from the pipeline, the slurry will impact on the buffer bottom cone 102 and spread out, thereby reducing the impact of the water flow. Subsequently, the scattered slurry will impact inside the inclined part 113 and then converge from the receiving part 112 towards the central position, so that it can converge at the central position of the sieve.

[0031] The above embodiments are only the preferred embodiments of the present utility model, and the scope of protection of the present utility model cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
