Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment equipment, specifically to an industrial wastewater sludge-liquid separation pretreatment device. Background Technology

[0002] The treatment of industrial wastewater often involves basic knowledge of physics, chemistry, physical chemistry and biochemistry, as well as the use of many corresponding facilities, equipment and automatic control devices. Moreover, many physical, chemical and biological testing methods are used in the analysis and monitoring. Wastewater generated in industrial production contains a large amount of waste residue, which greatly increases the difficulty of wastewater treatment. Therefore, it is necessary to use solid-liquid separation equipment to pre-treat the wastewater.

[0003] In existing technologies, sludge-liquid separation equipment generally filters waste residue through a filter screen. However, when the filter residue accumulates on the filter screen, it can easily cause the screen to become clogged. In this case, cleaning equipment is needed to clean the filter screen frequently, which is a troublesome problem when separating wastewater from sludge.

[0004] This utility model proposes an industrial wastewater sludge-liquid separation pretreatment device to solve the problem that sludge-liquid separation equipment generally filters waste residue through a filter screen. However, when the filter residue accumulates on the filter screen, it easily leads to filter screen blockage. At this time, it is necessary to use cleaning equipment to clean the filter screen frequently, which makes the sludge-liquid separation of wastewater quite troublesome. Utility Model Content

[0005] The purpose of this invention is to overcome the problem that in the above-mentioned background technology, sludge-liquid separation equipment generally filters waste residue through a filter screen. However, when the filter residue accumulates on the filter screen, it easily leads to filter screen blockage. At this time, it is necessary to use cleaning equipment to clean the filter screen frequently, which makes the sludge-liquid separation of wastewater quite troublesome.

[0006] Based on the above technical concept, the technical solution adopted by this utility model is as follows: An industrial wastewater sludge-liquid separation pretreatment device includes a treatment tank, which has a first treatment chamber and a second treatment chamber.

A driving component is provided on the outer wall of the treatment tank, and the driving component meshes with the rotary separation mechanism. A pushing mechanism is provided in the rotary separation mechanism. A corrugated guide groove is provided in the first treatment chamber, and the upper end of the pushing mechanism slides in cooperation with the inner wall of the corrugated guide groove.

[0007] Further defining the above technical solution, the upper end of the inner wall of the first processing chamber is connected to the inner wall of the second processing chamber through a discharge port, and the lower end of the inner wall of the first processing chamber is connected to the inner wall of the second processing chamber through a guide port.

[0008] As a further limitation of the above technical solution, the side wall of the processing box is provided with a cleaning port, and a sealing plate is hinged inside the cleaning port.

[0009] Further defining the above technical solution, the rotary separation mechanism includes a conical guide plate and a screening cylinder. The conical guide plate is fixedly disposed in the first processing chamber. A connecting ring is fixedly disposed on the outer wall of the upper end of the screening cylinder. The connecting ring is rotatably inserted into the bottom surface of the conical guide plate. A first gear is fixedly sleeved on the outer wall of the connecting ring.

[0010] Further defining the above technical solution, the extrusion mechanism includes an electric push rod, a pressure plate, and a first filter plate. The first filter plate is fixedly installed in the second processing chamber, and the electric push rod is fixedly installed on the top surface of the processing box. The protruding end of the electric push rod is inserted into the second processing chamber and fixedly connected to the pressure plate.

[0011] Further defining the above technical solution, the driving component includes a sealing cover, which is fixedly installed on the outer wall of the processing box. A motor is fixedly installed on the top surface of the sealing cover. The rotating shaft of the motor is inserted into the sealing cover and a second gear is fixedly fitted thereon.

[0012] Further defining the above technical solution, the feeding mechanism includes a second filter plate, with two limiting strips symmetrically arranged on the outer wall of the second filter plate. The two limiting strips slide in cooperation with the inner wall of the screening cylinder. Two guide rods are symmetrically arranged on the top surface of the second filter plate, with the upper ends of the two guide rods sliding in cooperation with the inner wall of the wavy guide groove.

[0013] Further defining the above technical solution, an inlet pipe is fixedly inserted into the top surface of the processing box, the inlet pipe being connected to the inner wall of the first processing chamber, and a drain pipe is fixedly inserted into the lower end of the side wall of the processing box, the drain pipe being connected to the inner wall of the first processing chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The rotary separation mechanism is driven by a drive unit to operate, and the wastewater is separated into solid and liquid under the action of centrifugal force. As the rotary separation mechanism rotates and cooperates with the wave-shaped guide groove, the pushing mechanism moves up and down reciprocatingly, thereby continuously pushing the waste residue accumulated in the rotary separation mechanism into the second treatment chamber for secondary treatment. At the same time, the rotary separation mechanism is cleaned, so the wastewater treatment is more convenient. When the screening cylinder rotates, it facilitates the separation of solid and liquid in the wastewater. The electric push rod can easily push the pressure plate down, thereby facilitating the compression of the waste residue on the first filter plate into blocks. At the same time, the residual waste liquid in the waste residue is squeezed out, resulting in better dewatering of the waste residue. Attached Figure Description

[0018] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0019] Example 1: This example provides an industrial wastewater sludge-liquid separation pretreatment device, such as... Figure 1 As shown, sludge-liquid separation equipment generally filters waste residue through a filter screen. However, when filter residue accumulates on the filter screen, it can easily cause the screen to become clogged. At this time, it is necessary to use cleaning equipment to clean the filter screen frequently. Therefore, the sludge-liquid separation of wastewater is a rather troublesome problem. The equipment includes a treatment tank 1, which has a first treatment chamber 2 and a second treatment chamber 3. The first treatment chamber 2 is equipped with a rotary separation mechanism 4, and the second treatment chamber 3 is equipped with a squeezing mechanism 5. The outer wall of the treatment tank 1 is equipped with a driving component 6, which meshes with the rotary separation mechanism 4. The rotary separation mechanism 4 is equipped with a pushing mechanism 7, and the first treatment chamber 2 is equipped with a corrugated guide groove 8. The upper end of the pushing mechanism 7 slides in cooperation with the inner wall of the corrugated guide groove 8.

[0020] First, wastewater is injected into the first treatment chamber 2. Then, the drive component 6 drives the rotary separation mechanism 4 to operate. Under the action of centrifugal force, the wastewater is separated into solid and liquid. As the rotary separation mechanism 4 rotates and cooperates with the wave-shaped guide groove 8, the pushing mechanism 7 moves up and down reciprocatingly, thereby continuously pushing the waste residue accumulated in the rotary separation mechanism 4 into the second treatment chamber 3. Then, the extrusion mechanism 5 extrudes the waste residue into blocks, so that the operator can collect the waste residue blocks.

[0021] Combination Figure 2 In an embodiment of this utility model, the upper end of the inner wall of the first processing chamber 2 is connected to the inner wall of the second processing chamber 3 through a discharge port 9, and the lower end of the inner wall of the first processing chamber 2 is connected to the inner wall of the second processing chamber 3 through a guide port 10. The waste residue can enter the second processing chamber 3 through the discharge port 9, and the waste liquid in the second processing chamber 3 can flow into the first processing chamber 2 through the guide port 10.

[0022] Combination Figure 2 In an embodiment of this utility model, a cleaning port 11 is provided on the side wall of the processing box 1, and a sealing plate 12 is hinged inside the cleaning port 11. The cleaning port 11 facilitates the operator to clean the waste residue blocks in the second processing chamber 3, and the sealing plate 12 facilitates the sealing of the cleaning port 11. A sealing strip is provided at the joint between the sealing plate 12 and the cleaning port 11 to increase the sealing performance of the connection between the two.

[0023] Example 2: Reference Figure 2 , Figure 3 The rotary separation mechanism 4 includes a conical guide plate 41 and a screening cylinder 42. The conical guide plate 41 is fixedly installed in the first processing chamber 2. A connecting ring 43 is fixedly installed on the outer wall of the upper end of the screening cylinder 42. The connecting ring 43 is rotatably inserted into the bottom surface of the conical guide plate 41. A first gear 44 is fixedly sleeved on the outer wall of the connecting ring 43. The screening cylinder 42 can be rotatably installed at the bottom of the conical guide plate 41 through the connecting ring 43. When the screening cylinder 42 rotates, it is convenient to separate the sludge and liquid from the wastewater.

[0024] The extrusion mechanism 5 includes an electric push rod 51, a pressure plate 52, and a first filter plate 53. The first filter plate 53 is fixedly installed in the second processing chamber 3. The electric push rod 51 is fixedly installed on the top surface of the processing box 1. The protruding end of the electric push rod 51 is inserted into the second processing chamber 3 and fixedly connected to the pressure plate 52. The electric push rod 51 facilitates pushing the pressure plate 52 downward, thereby facilitating the extrusion of the waste residue on the first filter plate 53 to extrude it into blocks, while squeezing out the residual waste liquid in the waste residue.

[0025] The driving component 6 includes a sealing cover 61, which is fixedly installed on the outer wall of the treatment tank 1. A motor 62 is fixedly installed on the top surface of the sealing cover 61. The rotating shaft of the motor 62 is inserted into the sealing cover 61 and a second gear 63 is fixedly fitted thereon. The second gear 63 extends into the treatment tank 1 and meshes with the first gear 44. The motor 62 can easily drive the second gear 63 to rotate, and then the second gear 63 drives the first gear 44 and the screening cylinder 42 to rotate, so as to achieve the separation of wastewater into solid and liquid under the action of centrifugal force, and the separation effect of wastewater into solid and liquid is better.

[0026] An inlet pipe 13 is fixedly inserted into the top surface of the treatment box 1. The inlet pipe 13 is connected to the inner wall of the first treatment chamber 2. A drain pipe 14 is fixedly inserted into the lower end of the side wall of the treatment box 1. The drain pipe 14 is connected to the inner wall of the first treatment chamber 2. The waste liquid can be easily transported to the screening cylinder 42 for screening through the inlet pipe 13. The waste liquid in the first treatment chamber 2 can be easily discharged through the drain pipe 14.

[0027] Example 3: Reference Figure 2 , Figure 3 The feeding mechanism 7 includes a second filter plate 71. Two limiting strips 72 are symmetrically arranged on the outer wall of the second filter plate 71. The two limiting strips 72 slide in cooperation with the inner wall of the screening cylinder 42. Two guide rods 73 are symmetrically arranged on the top surface of the second filter plate 71. The upper ends of the two guide rods 73 slide in cooperation with the inner wall of the wave-shaped guide groove 8. The limiting strips 72 cause the second filter plate 71 to rotate synchronously when the screening cylinder 42 rotates. When the second filter plate 71 rotates, it drives the guide rods 73 to slide along the inner wall of the wave-shaped guide groove 8. Thus, the guide rods 73 drive the second filter plate 71 to move up and down in the screening cylinder 42. When the second filter plate 71 is on the top, it is convenient to push the waste residue upward and discharge it into the second processing chamber 3 through the discharge port 9 for processing.

However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
