Description

Technical Field

[0001] This utility model relates to the field of horizontal centrifuge technology, and more specifically, to a horizontal sedimentation centrifuge for scum separation. Background Technology

[0002] A horizontal sedimentation spiral centrifuge mainly consists of a high-speed rotating drum, a spiral rotating in the same direction as the drum but at a slightly higher or lower speed, and a differential gear. When the suspension to be separated enters the centrifuge drum, the high-speed rotating drum generates a strong centrifugal force that causes solid waste with a density greater than the liquid phase to settle onto the inner wall of the drum. Due to the different speeds of the spiral and the drum, there is relative motion between them. This relative motion pushes the solid waste deposited on the inner wall of the drum towards the outlet at the smaller end of the drum for discharge. The separated clear liquid exits from the other end of the centrifuge.

[0003] Currently, since the discharge end discharges solid waste residue, the centrifugal force of the machine body itself is needed to throw the waste residue out of the through hole of the circular cover at the discharge port to achieve discharge. However, since it is not a direct discharge, the internal pressure of the circular cover is relatively large, and the discharge inside the machine body also maintains a certain pressure. However, when the discharge pressure inside the machine body changes, the discharge gap of the circular cover does not have the ability to adjust flexibly. It cannot flexibly detect changes in discharge pressure, which may lead to unsmooth discharge, thereby affecting the internal discharge and pressing, resulting in incomplete separation and dehydration. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a horizontal sedimentation centrifuge for scum separation to solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A horizontal sedimentation centrifuge for scum separation includes a frame on which a centrifuge body is mounted. A discharge hood is located on the left side of the centrifuge body. Equally spaced strip grooves are formed on the outer side of the discharge hood. A protective cover is mounted on the left side of the frame. A hydraulic cylinder is fixedly mounted on the protective cover. A redundant mechanism is mounted on the right end of the hydraulic cylinder. A movable disc is mounted on the right side of the redundant mechanism. The outer side of the movable disc is slidably connected to the inside of the discharge hood.

[0007] As a further description of the above technical solution: the redundant mechanism includes a spring, a push rod, and a pressure sensor. One end of the spring is fixedly connected to the interior of the movable end of the hydraulic cylinder, and the other end of the spring is fixedly connected to the push rod. The other end of the push rod is inserted into the right side of the movable end of the hydraulic cylinder and rotatably connected to the moving disk. The pressure sensor is fixedly installed on the end of the movable end of the hydraulic cylinder.

[0008] As a further description of the above technical solution: the movable disc has a conical surface on the side facing the conical outlet side of the centrifuge body.

[0009] As a further description of the above technical solution: a scraper is fixedly connected to the outer side of the discharge hood, and the scraper is inclined.

[0010] As a further description of the above technical solution: an extended sealing ring is fixedly connected to the outer edge of the side of the moving disc away from the main body of the machine, and the outer side of the extended sealing ring is slidably connected to the inner side of the discharge hood.

[0011] As a further description of the above technical solution: support legs are fixedly installed at the four corners of the bottom of the frame, and rubber shock-absorbing seats are installed at the bottom of the support legs.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] This solution uses a redundant mechanism in conjunction with a hydraulic cylinder to adjust the moving disc, thereby changing the discharge cross-sectional area of ​​the strip trough. This enables the device to flexibly adjust the discharge pressure according to changes in the internal pressure of the equipment, ensuring internal pressure balance and more thorough dewatering.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-4In this utility model, the horizontal sedimentation centrifuge for scum separation includes a frame 1, a centrifuge body 2 mounted on the frame 1, a discharge hood 8 on the left side of the centrifuge body 2, and strip grooves 3 arranged at equal intervals on the outer side of the discharge hood 8. A protective cover 4 is mounted on the left side of the frame 1, a hydraulic cylinder 5 is fixedly mounted on the protective cover 4, a redundancy mechanism 6 is mounted on the right end of the hydraulic cylinder 5, a moving disk 7 is mounted on the right side of the redundancy mechanism 6, and the outer side of the moving disk 7 is slidably connected to the inside of the discharge hood 8.

[0022] In this invention, the centrifuge body 2 is supported by the frame 1. During operation, when the centrifuge body 2 separates materials, solid waste is discharged from the conical port into the discharge hood 8. The discharge hood 8 rotates synchronously with the centrifuge body 2, throwing out the discharged solid waste. Under the isolation of the protective cover 4, splashing and falling to the bottom for discharge is prevented. When the discharge pressure inside the centrifuge body 2 changes, if the pressure change is less than the threshold of the redundant mechanism 6, the hydraulic cylinder 5 does not start. At this time, only the redundant mechanism 6 performs mechanical adaptive adjustment to maintain the internal and external pressure balance and ensure the separation effect. If the pressure change is greater than the threshold of the redundant mechanism 6, the centrifuge body 2 will not start. At this time, the hydraulic cylinder 5 starts, driving the redundant mechanism 6 to operate synchronously and moving the moving disc 7 along the inside of the discharge hood 8 to change the outlet cross-sectional area of ​​the strip groove 3, thereby changing the amount of solid waste discharged and adjusting the discharge pressure. This achieves flexible and adaptive adjustment, enabling the device to flexibly adjust the discharge pressure according to changes in the internal pressure of the equipment, ensuring internal pressure balance and more thorough dewatering. This solves the problem in the existing technology where the discharge gap of the circular hood does not have flexible adjustment capability when the discharge pressure inside the machine changes, and cannot flexibly detect changes in discharge pressure, which may lead to uneven discharge, thus affecting the internal discharge pressure and resulting in incomplete separation and dewatering.

[0023] Please see Figure 2 The redundant mechanism 6 includes a spring 61, a push rod 62, and a pressure sensor 63. One end of the spring 61 is fixedly connected to the inside of the movable end of the hydraulic cylinder 5, and the other end of the spring 61 is fixedly connected to the push rod 62. The other end of the push rod 62 is inserted into the right side of the movable end of the hydraulic cylinder 5 and rotatedly connected to the moving disk 7. The pressure sensor 63 is fixedly installed on the end of the movable end of the hydraulic cylinder 5.

[0024] In this invention, the pressure of the movable disk 7 is adjusted within a certain threshold range by the spring 61 and the push rod 62. When the internal pressure is too high, one side of the movable disk 7 contacts and squeezes the pressure sensor 63. When the pressure value is higher than the set value, the hydraulic cylinder 5 is activated to drive the push rod 62 and the movable disk 7 to actively move and adjust, thereby realizing the device's adaptive and flexible adjustment of pressure.

[0025] Please see Figure 1 and Figure 4 The movable disc 7 has a conical surface 71 on the side facing the conical outlet of the centrifuge body 2.

[0026] In this invention, the conical surface 71 disperses the solid waste residue during horizontal discharge and guides it to the surrounding strip grooves 3, thereby improving the smoothness of discharge.

[0027] Please see Figure 3 Among them, a scraper 81 is fixedly connected to the outside of the discharge hood 8, and the scraper 81 is inclined.

[0028] In this invention, the scraper 81 prevents waste residue from sticking to the inner wall of the protective cover 4, resulting in good material discharge.

[0029] Please see Figure 1 Among them, an extended sealing ring 72 is fixedly connected to the outer edge of the side of the moving disc 7 away from the main body 2, and the outer side of the extended sealing ring 72 is slidably connected to the inner side of the discharge hood 8.

[0030] In this invention, by extending the sealing ring 72, the right side of the strip groove 3 will not be exposed when the moving disk 7 moves to the left, making the structure more reasonable.

[0031] Please see Figure 1 Among them, the four corners of the bottom of the frame 1 are fixedly installed with support legs 9, and the bottom of the support legs 9 are installed with rubber shock absorber seats 91.

[0032] In this invention, the rubber shock-absorbing seat 91 at the bottom of the support leg 9 provides shock absorption support for the equipment, resulting in good shock absorption.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
