Description

Technical Field

[0001] This utility model relates to the field of nozzle-type disc centrifuge technology, and in particular to a nozzle-type disc centrifuge that automatically adjusts the discharge stability. Background Technology

[0002] The nozzle-type disc centrifuge is a highly efficient centrifugal separation device, mainly used for the separation of liquid-liquid, liquid-solid, or liquid-liquid-solid three-phase mixtures. It generates a powerful centrifugal force through high-speed rotation, enabling the separation of substances of different densities within the centrifugal force field. The disc design increases the separation area and improves separation efficiency, allowing for rapid and efficient separation of the various phases in a mixture. For some difficult-to-separate fine particles or liquid-liquid mixtures, such as oil-water mixtures and biological fermentation broths, the nozzle-type disc centrifuge can achieve good separation results and obtain high-purity separated products.

[0003] In daily work, it has been found that existing nozzle-type disc centrifuges mainly discharge slag through the slag discharge pipe. However, during the slag discharge process, the inner diameter of the pipe is not easy to adjust. When the slag discharge is blocked, it will disrupt the internal pressure balance of the centrifuge, interfere with the normal separation process of the material, and thus lead to unstable discharge speed and flow rate. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where the slag discharge process is obstructed due to the inconvenience of adjusting the inner diameter of the pipe, thus affecting the stability of the discharge. Therefore, this invention proposes a nozzle-type disc centrifuge that automatically adjusts the discharge stability.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a nozzle-type disc centrifuge with automatic adjustment of discharge stability, comprising a machine body, on which a nozzle-type disc centrifuge body is mounted. A feed pipe, a discharge pipe, and a slag discharge pipe are respectively installed on the nozzle-type disc centrifuge body. An adjustment device is provided on the surface of the slag discharge pipe. The adjustment device includes a hollow tube fixed to one end of the slag discharge pipe. An elastic sleeve is fixedly connected to the inner wall of the hollow tube. Multiple sets of pull rods are fixedly connected to the surface of the elastic sleeve. The multiple sets of pull rods are slidably connected to the inner wall of the hollow tube. A connecting plate is fixedly connected to the surface of each set of pull rods. A pushing part is provided between the hollow tube and the connecting plate. A spring is directly provided between the pull rod and the inner wall of the hollow tube. Through the above components, when the discharge from the slag discharge pipe is blocked and unstable, the pushing part can control the sliding rod and the pull rod to move. The pull rod drives the elastic sleeve to deform, increasing the inner diameter, thereby allowing the slag to be discharged better and improving the discharge stability.

[0006] Preferably, the elastic sleeve is made of rubber.

[0007] Preferably, the lower port diameter of the elastic sleeve is larger than the upper port diameter, thereby facilitating better material discharge.

[0008] Preferably, the pushing part includes an auxiliary block fixed on the surface of the connecting plate, and multiple sets of cylinders are fixedly connected to the surface of the hollow tube. A push ring is fixedly connected to the output end of the cylinder. By using the above components, the cylinder is opened, and the cylinder drives the push ring to move. The push ring squeezes the auxiliary block, thereby driving the connecting plate and the pull rod to move, so as to realize the adjustment operation.

[0009] Preferably, the two ends of the spring are fixedly connected to the inner wall of the pull rod and the hollow tube, respectively. Through the above components, the spring can drive the pull rod and the connecting plate to reset, which can better allow the elastic sleeve to return to its original state.

[0010] Preferably, a plurality of guide rods are fixedly connected to the surface of the hollow tube, and the guide rods are slidably connected to the inner wall of the connecting plate. Through the above-mentioned components, the plurality of guide rods can guide the connecting plate and improve the overall stability.

[0011] Preferably, a support frame is fixedly connected to the surface of the machine body. Through the above-mentioned components, the support frame can support the slag discharge pipe and improve stability.

[0012] Preferably, the pull rod includes a rod body and a pull block, wherein the pull block is fixed to the rod body.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting an adjustment device, the connecting plate and the pull rod can be moved by pushing the part, thereby adjusting the inner diameter of the elastic sleeve, so that the slag can be discharged more smoothly, ensuring the stability of slag discharge, reducing the centrifuge operation failure caused by blockage, and preventing unstable discharge, thus ensuring the normal operation of the centrifuge and improving the reliability of the equipment.

[0015] In this invention, the spring design allows the elastic sleeve to easily return to its original position after adjustment, preparing it for the next adjustment and ensuring the repeatability and long-term stability of the adjustment device.

[0016] In this invention, the lower port diameter of the elastic sleeve is larger than the upper port diameter, which provides a wider discharge channel for the slag. Especially when the amount of slag is large or the particles are large, it can effectively reduce the risk of blockage and allow the slag to be discharged from the slag discharge pipe more smoothly, thereby improving the slag discharge efficiency.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a nozzle-type disc centrifuge with automatic adjustment of discharge stability, including a body 1, a nozzle-type disc centrifuge body 2 is provided on the body 1, a feed pipe 3, a discharge pipe 4 and a slag discharge pipe 5 are respectively installed on the nozzle-type disc centrifuge body 2, and an adjustment device 6 is provided on the surface of the slag discharge pipe 5.

[0025] Specifically, the adjusting device 6 includes a hollow tube 61 fixed to one end of the slag discharge pipe 5. An elastic sleeve 63 is fixedly connected to the inner wall of the hollow tube 61. The elastic sleeve 63 is made of rubber. The lower port diameter of the elastic sleeve 63 is larger than the upper port diameter. Multiple sets of pull rods 64 are fixedly connected to the surface of the elastic sleeve 63. The multiple sets of pull rods 64 are slidably connected to the inner wall of the hollow tube 61. A connecting plate 65 is fixedly connected to the surface of each set of pull rods 64. A pushing part 67 is provided between the hollow tube 61 and the connecting plate 65. A spring 66 is directly provided between the pull rod 64 and the inner wall of the hollow tube 61.

[0026] In this implementation plan: when the discharge pipe 5 is blocked and unstable, the pusher 67 can control the slide rod and the pull rod 64 to move. The pull rod 64 drives the elastic sleeve 63 to deform, increasing the inner diameter, thereby allowing the slag to be discharged better and improving the discharge stability.

[0027] Specifically, the pushing part 67 includes an auxiliary block 673 fixed on the surface of the connecting plate 65, and multiple sets of cylinders 672 are fixedly connected to the surface of the hollow tube 61. A push ring 671 is fixedly connected to the output end of the cylinder 672.

[0028] In this implementation scheme: when the cylinder 672 is opened, the cylinder 672 drives the push ring 671 to move, the push ring 671 presses the auxiliary block 673, thereby driving the connecting plate 65 and the pull rod 64 to move, so as to realize the adjustment operation.

[0029] Specifically, the two ends of the spring 66 are fixedly connected to the inner wall of the pull rod 64 and the hollow tube 61, respectively.

[0030] In this implementation scheme: the spring 66 can drive the pull rod 64 and the connecting plate 65 to reset, which can better allow the elastic sleeve 63 to return to its original state.

[0031] Specifically, multiple guide rods 68 are fixedly connected to the surface of the hollow tube 61. The guide rods 68 are slidably connected to the inner wall of the connecting plate 65. The multiple guide rods 68 can guide the connecting plate 65 and improve the overall stability.

[0032] Specifically, a support frame 62 is fixedly connected to the surface of the machine body 1. The support frame 62 can support the slag discharge pipe 5 and improve its stability.

[0033] Specifically, the lever 64 includes a lever body 641 and a lever block 642, with the lever block 642 fixed to the lever body 641.

[0034] Working principle: During use, if a blockage occurs when discharging slag through the slag discharge pipe 5, the cylinder 672 is opened. The cylinder 672 drives the push ring 671 to move, and the push ring 671 squeezes the auxiliary block 673, thereby driving the connecting plate 65 and the pull rod 64 to move. The pull rod 64 causes the rubber elastic sleeve 63 to deform, and the spring 66 is stressed, thereby increasing the inner diameter of the elastic sleeve 63. The lower port diameter of the elastic sleeve 63 is larger than the upper port diameter, which can facilitate smoother material discharge and ensure the overall stability of the discharge. During reset, the cylinder 672 can drive the push ring 671 to reset. After the push ring 671 resets, the spring 66 drives the pull rod 64 and the connecting plate 65 to reset, so that the elastic sleeve 63 returns to its original position.
