Description

Technical Field

[0001] The utility model relates to the technical field of mine minerals, in particular to a uniform feeding device for a belt-type vacuum dehydration filter. Background Art

[0002] Belt vacuum dewatering filter is a common equipment when treating liquid waste generated in industrial or environmental processes. This type of filter is usually used for sludge dewatering treatment. Its efficiency and effect largely depend on how to evenly distribute the material to be treated onto the filter belt. The uniform feed device plays a key role in this process.

[0003] The existing feed hopper adopts a single or two feed ports, combined with baffles to achieve uniform distribution of slurry on the filter cloth. This form meets the requirements under most working conditions, but when the feed pipe is inclined and the solid content is very high, uneven distribution will still occur. Uneven materials can easily cause the rubber belt to deviate and the filter cake washing effect. Therefore, a belt-type vacuum dehydration filter uniform feeding device is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a uniform feeding device for a belt-type vacuum dehydration filter, aiming to improve the problem in the prior art that uneven materials may cause deviation of the rubber belt and poor washing effect of the filter cake.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A uniform feeding device for a belt-type vacuum dehydration filter comprises a box body, two sides of the top of the box body are fixedly connected with secondary distribution pipes, the tops of the two secondary distribution pipes are fixedly connected with a primary feeding pipe, the inner wall of the box body is fixedly connected with a primary baffle, the bottom of the inner wall of the box body is fixedly connected with a secondary baffle, and the bottom inner wall of the box body is fixedly connected with a limiting component;

[0007] As a further description of the above technical solution:

[0008] The limiting component comprises a porous plate, the outside of which is fixedly connected to the bottom inner wall of the box body, and a plurality of slots are formed on the outside of the porous plate.

[0009] The utility model has the following beneficial effects:

[0010] In the utility model, the new feed hopper adopts one total inlet, which is divided into two downwards, and then into four. The number of pipe openings increases, and the pipe diameter gradually decreases. Two layers of baffles are arranged inside the hopper body, and a porous plate is arranged at the discharge end. The aperture and number of the porous plate can be determined according to the flow rate, solid content and sedimentation speed of the material. The porous plate can play the role of limiting flow and even distribution, so that the slurry flows to the end with less, thereby avoiding causing the rubber belt to deviate and affecting the washing effect of the filter cake.

[0017] 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.

[0018] Reference Figure 1 The utility model provides an embodiment: a uniform feeding device of a belt type vacuum dehydration filter, comprising a box body 3, both sides of the top of the box body 3 are fixedly connected with secondary distribution pipes 2, the box body 3 can support the secondary distribution pipes 2, the tops of the two secondary distribution pipes 2 are fixedly connected with a primary feeding pipe 1, the slurry in the sewage treatment process first enters through the primary feeding pipe 1, and then the slurry will enter the secondary distribution pipe 2.

[0019] refer to Figure 2-Figure 4The inner wall of the box body 3 is fixedly connected with a primary baffle 4, which is set at an inclined angle to change the flow direction of the fluid and increase the contact time of the fluid in the box body 3, so that solid particles have more opportunities to settle. The bottom of the inner wall of the box body 3 is fixedly connected with a secondary baffle 5, which further balances and disperses the fluid to prepare for final filtration.

[0020] The bottom inner wall of the box body 3 is fixedly connected with a restriction assembly, which includes a porous plate 6. The outside of the porous plate 6 is fixedly connected to the bottom inner wall of the box body 3. The outside of the porous plate 6 is provided with a plurality of slots, which accurately control the flow rate and distribution of the slurry. The design of the porous plate 6 ensures that the slurry is distributed as evenly as possible before reaching the filter belt, thereby maximizing the filtration efficiency.

[0021] Working principle: The whole process starts with the sludge feeding from the primary feed pipe 1, which is evenly dispersed into the box 3 through the secondary distribution pipe 2. The slurry first contacts the primary baffle 4, then flows to the secondary baffle 5. The setting of these baffles optimizes the flow path and speed, and finally evenly distributes to the filter belt below through the precise slots of the porous plate 6. This carefully designed multi-stage process ensures the maximum filtration efficiency and the extension of the service life of the filter belt. The aperture and number of the porous plate 6 can be determined according to the flow rate, solid content and sedimentation rate of the material. The porous plate 6 can play the role of limiting flow and uniform distribution, so that the slurry flows to the end with less solids.
