[0007] On the basis of the above technical solutions, the utility model can be further improved as follows.

[0008] Further, the first filtering component includes a filter net and a vibration motor. Among them, fixed frames are arranged at intervals around the outer periphery of the frame on the four sides of the filter net. The fixed frames are concentric with the frame of the filter net and a rubber pad is filled in the gap between the two. The front and back sides of the rubber pad are flush with the front and back sides of the frame of the filter net. The vibration motor is embedded inside the frame of the filter net.

[0020] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs. The terms used in the description of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0022] Combined with Figures 1-3 As shown, a sewage collection device for a filter press device includes:

[0023] The support frame 1, which is a support structure for the filter press device and the sewage device, is provided with 4 groups and arranged at intervals in a rectangle;

[0024] The water storage tank 2, which is a rectangular metal box body, is coated with an anti-adhesion coating on the inner side wall, and is arranged in the middle of the support frame 1, and the side walls are respectively fixedly connected to the 4 groups of support frames 1 to form a stable support, and is mainly used to receive the wastewater separated by the filter press device;

[0025] The first filtering component 3 is arranged inside the water storage tank 2 and is used for preliminary solid-liquid separation of the wastewater to prevent subsequent filtering from being blocked;

[0026] The second filtering component 4 is arranged at the bottom of the water storage tank 2 and is used for secondary filtering and separation of the wastewater to completely remove the impurities inside it for subsequent recycling;

[0027] The drain pipe 5 is arranged at the bottom of the support frame 1 and is arranged horizontally and is communicated with the second filtering component 4 to convey the filtered and recycled sewage.

[0028] Specifically; the first filtering component 3 includes a filter screen 31 and a vibration motor 33. A fixing frame 32 is sleeved on the outer edge of the frame of the filter screen 31. The fixing frame 32 and the frame of the filter screen 31 are concentrically arranged and there is a gap between them. A rubber pad 34 is filled in this gap, and the rubber pad 34 is flush with the surfaces of the fixing frame 32 and the filter screen 31. Its purpose is to act as a buffer structure. The vibration motor 33 is embedded inside the frame of the filter screen 31 and vibrates to sieve the impurities attached to its surface, thereby preventing the surface of the filter screen from being blocked, so as to quickly separate the solid and liquid of the sewage in the water storage tank 2.

[0029] On the inner side wall of the water storage tank 2, there is also a fixing groove 21 which extends obliquely upward along the inner wall of the water storage tank 2 and forms a rectangular opening 22 on the outer side wall of the water storage tank 2. The fixing frame 32 slides and is inserted into the interior along the rectangular opening 22 to complete the fixation. Moreover, a limiting groove 23 is provided on the water storage tank 2 and is arranged at both ends of the rectangular opening 22 respectively. At the same time, a flange is provided on the outer side of the fixing frame 32 to make it fit inside the limiting groove 23 and is locked and fixed by bolts. A handle is additionally provided at the center of its outer side for subsequent staff to take it out for cleaning or replacement.

[0030] The solid waste screened by the filter screen should be centrally collected synchronously. Therefore, in this embodiment, a waste discharge port should also be opened on the side of the water storage tank 2 away from the rectangular opening 22 and is arranged just near the lower side of the fixing frame 32. Thus, during the operation of the vibration motor 33, by means of vibration, the separated solid waste is driven to be discharged from the waste discharge port, and a sewage pipe is additionally arranged at the waste discharge port to guide it to a designated area for recycling.

[0031] The second filtering component 4 is made by combining multiple cylindrical filters. Each cylindrical filter 41 is an independent individual and is only connected and fixed to each other by brackets. Then, the brackets used to fix the cylindrical filters 41 are fixedly connected to the two side support frames 1. In addition, the cylindrical filters 41 should also be able to be disassembled and assembled flexibly to ensure more convenience during subsequent replacement of the filter elements.

[0032] At the top of each of the multiple cylindrical filters 41, there is a water delivery pipe 6. Corresponding to the bottom of the water storage tank 2, there are several circular through holes. The multiple water delivery pipes 6 are respectively connected to the circular through holes one by one, so as to smoothly discharge the sewage in the water storage tank 2 into the interior of the cylindrical filters 41.

[0033] At the bottom of the cylindrical filter 41, there is a water outlet which extends downward and is connected to the drain pipe 5. Therefore, the filtered water can be recycled through the drain pipe 5, and the impurities separated by filtration remain inside the cylindrical filter 41 and are regularly disassembled and cleaned.

[0034] In addition, it should also be ensured that during regular maintenance, the equipment operates without stopping. Therefore, a water stop valve 7 can be set at the connection between the cylindrical filter 41 and the water delivery pipe 6 to control its on-off effect, so as to disassemble and maintain a single cylindrical filter 41, while the other cylindrical filters 41 can ensure the normal operation of the equipment, greatly improving the working efficiency of the pressure filtration equipment.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of the present invention.
