[0003] High-energy filter press is an intermittent filtering device, which is mainly used for solid-liquid separation. The main working steps of the filter press are slurry dehydration and extrusion dehydration. After slurry dehydration or extrusion dehydration, the compressed air enters one side of the filter cake in the filter chamber and passes through the filter cake, and carries liquid water from the other side of the filter cake through the filter cloth. This operation is called wind dehydration. The filter press needs to be flushed after entering the slurry, otherwise it will cause pipeline blockage.

[0004] At present, the traditional buffer box equipped with high-energy filter presses cannot properly discharge backwash water (also known as backwash liquid) and drying air, and often causes the filtrate water in the plant to flush out of the ditch, causing safety hazards to passers-by, and also affecting the sanitary environment of the plant, which requires a lot of manpower and material resources to clean every day. In addition, part of the filtrate will be brought out of the plant when the air is swept, which poses a greater safety hazard when it freezes in winter, and also affects the cleanliness of the plant environment when it is not frozen.

[0005] The utility model provides a backwash water and drying air buffer device for a high-energy filter press, which can reduce the influence of backwash water and drying air on production operations, has obvious buffering effect, can reduce the workload of people, and has the advantages of safety, practicality, low cost, easy installation, simple structure, etc. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] In one embodiment, a high-energy filter press backwash water and drying air buffer device is designed, specifically a buffer box with simple structure, low price, and capable of effectively reducing the discharge force of high-energy filter press backwash water and drying air.

[0031] Figure 1 1 is a schematic diagram of the structure of a high-energy filter press backwash water and drying air buffer device according to an embodiment. It should be noted that: Figure 1 What is shown is merely one embodiment and any component shown therein is not necessarily required. Figure 1 The high-energy filter press backwash water and drying air buffer device shown includes a box body 1, a backwash water pipe 4, a drying air pipe 6, a first drain pipe 2 connected to the upper part of the box body 1, a second drain pipe 8 connected to the lower part of the box body 1, a first baffle 10 and a second baffle 12 inside the box body 1 and located at the bottom of the box body 1, and a third baffle 11 inside the box body 1 and located at the top of the box body 1, and the third baffle 11 is located between the first baffle 10 and the second baffle 12 in the horizontal direction.

[0032] Using the high-energy filter press backwash water and drying air buffer device of this embodiment, during operation, backwash water enters through the backwash water pipe 4, is buffered by the first baffle 10 and the third baffle 11, and is finally discharged from the second exhaust pipe 8. Drying air enters through the drying air pipe 6, is buffered by the third baffle 11 and the second baffle 12, and is finally mainly discharged from the first exhaust pipe 2, and a small amount is discharged from the second exhaust pipe 8.

[0033] By using the high-energy filter press backwash water and drying air buffer device of this embodiment, the pressure of water and wind during discharge can be effectively reduced, and the filtrate water in the ditch can be avoided from splashing when the water and wind are discharged, thereby maintaining the factory environment. In addition, when sweeping the wind in winter, it can prevent the liquid in the box from being brought outside the factory to freeze, effectively reducing production safety hazards. In addition, the high-energy filter press backwash water and drying air buffer device of this embodiment has a simple structure, low maintenance cost, and is durable.

[0034] In one embodiment, the first baffle 10 may be arranged tilted. In one embodiment, the angle between the first baffle 10 and the bottom plate of the box body 1 is between 30° and 60°, preferably about 45°.

[0035] In one embodiment, the high-energy filter press backwash water and drying air buffer device further comprises a first rubber lining 13 and a second rubber lining 14 located at the bottom of the housing 1, wherein the first rubber lining 13 is located between the first baffle 10 and the second baffle 12, and the second rubber lining 14 is located between the second baffle 12 and the side wall of the housing 1. The first rubber lining 13 and the second rubber lining 14 can withstand the impact force to prevent the backwash water and the drying air from directly hitting the bottom of the housing, protect the corresponding parts in the housing from damage, and further improve the service life of the buffer device.

[0036] In one embodiment, the box body 1 is connected to the backwash water pipe 4, the blow-drying air pipe 6, the first exhaust pipe 2, and the second exhaust pipe 8 through flanges 5, 7, 3, and 9 respectively, which is convenient for disassembly and maintenance of the device.

[0037] In one embodiment, sealing rubber strips 15 are installed at one or more (maximum 12) edges inside the box body 1 to prevent backwash water from splashing out through the gaps and affecting the sanitary environment of the factory.

[0038] In one embodiment, four feet 16 are installed at the bottom of the outer side of the box body 1 to prevent the bottom of the box body 1 from rusting in a humid environment and to facilitate cleaning.

[0039] In one embodiment, a semicircular channel (e.g., a semicircular channel with a diameter of 15 cm) is provided at the bottom of the first baffle 10, so that the remaining liquid in the box can flow out slowly. In one embodiment, two semicircular channels (e.g., a semicircular channel with a diameter of 10 cm) are provided at the bottom of the first baffle 10, so that the buffer tank has two drainage modes, namely, fast drainage and slow drainage.

[0040] In one embodiment, the second baffle 12 is arranged vertically and has a rectangular opening at the bottom (for example, a rectangular opening of 20 cm long and 10 cm wide). When sweeping the wind, it can change the direction of the wind so that the wind flows up and down to reduce the impact force. It can also act as a diversion when backwash water enters, thereby reducing the pressure and impact force inside the box.

[0041] In one embodiment, the second drain pipe 8 is a three-way pipe, which allows wind and water to be discharged from both sides to reduce the drain pressure. In one embodiment, the length of the second drain pipe 8 can be extended to make it closer to the bottom of the trench to facilitate diversion and filtrate circulation.

[0042] In one embodiment, a high-energy filter press backwash water and drying air buffering device includes a box body 1, which can be 180cm long, 100cm wide and 160cm high. The backwash water is buffered by the backwash water pipe 4 through the first baffle 10 and the third baffle 11, and finally discharged by the second emptying pipe 8. The drying air is buffered by the third baffle 11 and the second baffle 12 through the drying air pipe 6, and finally mainly discharged by the first emptying pipe 2, and a small amount is discharged from the second emptying pipe 8. The first baffle 10 is placed at an angle of 45°, the first baffle 10 is 100cm long and 70cm wide, and a semicircular channel with a diameter of 15cm is opened at the bottom of the first baffle 10, so that the remaining liquid in the box can flow out slowly. The second baffle 12 is placed vertically, 120cm long and 100cm wide, and a rectangular channel with a length of 20cm and a width of 10cm is opened at the bottom. A rubber lining with a thickness of 20 mm is installed between the first baffle plate 10 and the second baffle plate 12 and between the second baffle plate 12 and the side wall of the box body 1 .

[0043] The utility model discloses a backwash water and drying air buffer device for a high-energy filter press, which has a simple structure and is easy to install, and particularly focuses on practicability and maintainability.
