Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a tubular centrifuge hub. Background Technology

[0002] The rotating hub of a tubular centrifuge is the core rotating separation component of the equipment. It is cylindrical and consists of a tube body, end caps, liquid phase discharge holes, feed inlets, and other functional structures. It is mostly made of high-strength and corrosion-resistant materials such as stainless steel and titanium alloy. Its core function is to convert kinetic energy into a strong centrifugal force of thousands to tens of thousands of times gravity through high-speed rotation, so that the solid-liquid mixture can be separated inside the tube. Solid particles are deposited on the inner wall, while the liquid phase flows directionally along the inner side and is discharged through the preset channels. It must have precise dynamic balance and high rigidity, which directly determines the separation efficiency, throughput, and equipment operation stability. It is a key component to meet the solid-liquid separation needs of industries such as chemical and pharmaceutical.

[0003] The patent application number "202323639739.0" describes a centrifuge drum with wear-resistant function. The centrifuge drum is equipped with a drum body, a mounting plate, a rubber scraper, and brush strips. The mounting plate, which is fixed to the centrifuge housing with screws, is located on the lower left side of the drum body. The rubber scraper, which is attached to the upper middle part of the mounting plate and fits against the drum body, is attached to the right front side of the rubber scraper at equal intervals and is connected to the drum body. Therefore, it is convenient to scrape and clean the drum body and avoid clogging that would affect its use.

[0004] However, the centrifuge hub has the following problems when in use. The centrifuge hub is cleaned by brush strips, but the brush strips can only clean the outer surface of the hub and cannot clean the inside of the liquid phase holes on the outer wall of the hub. The liquid phase holes are prone to clogging after long-term use, which affects the use of the centrifuge. Utility Model Content

[0005] The purpose of this invention is to provide a tubular centrifuge hub that solves the problem that the brush strips of existing centrifuge hubs can only clean the outer surface of the hub and cannot clean the inside of the liquid phase holes on the outer wall of the hub. The liquid phase holes are prone to clogging after long-term use, which affects the use of the centrifuge.

[0006] To achieve the above objectives, a tubular centrifuge hub is provided, comprising: a cleaning cylinder, a cylinder cover on the top of the cleaning cylinder, a bearing on the bottom wall of the cleaning cylinder, a feed pipe inside the bearing, the top end of the feed pipe communicating with the hub body, a liquid phase hole on the outer wall of the hub body, a bracket fixedly connected to the outer wall of the cleaning cylinder, a sleeve fixedly connected to the inner wall of the bracket, a telescopic rod movably connected inside the sleeve, a cleaning plate fixedly connected to the other end of the telescopic rod, a screw inside the bracket, and a cleaning rod fixedly connected to the inner side of the cleaning plate, which facilitates cleaning of the liquid phase hole and thus avoids clogging. A rotating shaft is fixedly connected to the bottom of the cylinder cover, a screw conveyor is fixedly connected to the outer wall of the rotating shaft, a connecting rod is fixedly connected to the outer wall of the rotating shaft, and a scraper is provided at the end of the connecting rod, which improves the rate of solid-liquid separation of materials and can clean the inner wall of the rotating hub body at the same time.

[0007] According to the aforementioned tubular centrifuge hub, the number of cleaning plates is four, and the four cleaning plates are arranged in a circumferential array inside the cleaning cylinder.

[0008] According to the aforementioned tubular centrifuge hub, the liquid phase holes are equidistantly opened on the outer wall of the hub body, and the shape, size, position and number of the liquid phase holes correspond to the cleaning rods, which facilitates the cleaning of the liquid phase holes.

[0009] According to the aforementioned tubular centrifuge hub, the shape and size of the telescopic rod are matched with the shape and size of the sleeve, and the telescopic rod is slidably connected to the inner wall of the sleeve.

[0010] According to the aforementioned tubular centrifuge hub, a screw hole is provided on one side of the support. The inner wall of the screw hole and the outer wall of the screw rod are both provided with threads. The screw hole and the screw rod are engaged with each other through threads, which facilitates the movement of the cleaning plate and the cleaning rod, thereby facilitating the cleaning of the liquid phase hole.

[0011] According to the aforementioned tubular centrifuge hub, a rotating shaft seat is provided on one side of each cleaning plate, and one end of each screw is rotatably connected to the rotating shaft seat to facilitate the rotation of the screw.

[0012] According to the aforementioned tubular centrifuge hub, the scraper is in contact with the inner wall of the hub body, and the scraper is made of rubber material. The scraper can remove residual material on the inner wall of the hub body, thereby facilitating the cleaning of its inner wall.

[0013] The above-mentioned solution has the following beneficial effects: 1. The tubular centrifuge hub has four sets of supports installed on the outer wall of the cleaning cylinder. Each support has a screw installed inside. Rotating the screw can drive the cleaning plate to move. Multiple sets of cleaning rods are installed on the inner side of the cleaning plate, and the cleaning rods correspond one-to-one with the liquid phase holes on the hub body. When the cleaning rods move with the cleaning plate and are inserted into the liquid phase holes, they can push out the impurities that are clogging the liquid phase holes, thereby cleaning them and preventing them from affecting the use of the centrifuge due to blockage. This improves the practicality of the tubular centrifuge hub.

[0014] 2. The tubular centrifuge hub has a rotating shaft installed at the bottom of the cylinder cover, and a screw conveyor installed on the outer wall of the rotating shaft. When the hub body rotates, the screw conveyor can transport the material at the bottom of the hub body to the top, making it evenly dispersed and improving the solid-liquid separation efficiency of the material. In addition, a scraper is installed on the outer wall of the rotating shaft. During the rotation of the hub body, the scraper can scrape off the material remaining on its inner wall, thereby cleaning the inner wall of the hub body.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-4 This utility model discloses a tubular centrifuge hub, comprising: a cleaning cylinder 1, a cylinder cover 2 covering the top of the cleaning cylinder 1, a bearing 3 on the bottom wall of the cleaning cylinder 1, a feed pipe 4 inside the bearing 3, the top end of the feed pipe 4 connecting to the hub body 5, a liquid phase hole 6 on the outer wall of the hub body 5, a bracket 7 fixedly connected to the outer wall of the cleaning cylinder 1, a sleeve 8 fixedly connected to the inner wall of the bracket 7, a telescopic rod 9 movably connected inside the sleeve 8, a cleaning plate 10 fixedly connected to the other end of the telescopic rod 9, a screw 11 inside the bracket 7, and a cleaning rod 13 fixedly connected to the inner side of the cleaning plate 10. Rotating the screw 11 in the forward direction can drive the cleaning plate 10 to move towards the hub body 5, thereby driving the cleaning rod 13 to move. The cleaning rod 13 corresponds one-to-one with the liquid phase hole 6. Therefore, when the cleaning rod 13 moves and inserts into the liquid phase hole 6, it can push out the impurities inside, thereby avoiding blockage and facilitating the subsequent use of the centrifuge.

[0020] There are four cleaning plates 10, and the four cleaning plates 10 are arranged in a circular array inside the cleaning cylinder 1.

[0021] Liquid phase holes 6 are equidistantly opened on the outer wall of the rotating hub body 5, and the shape, size, position and number of liquid phase holes 6 correspond to the cleaning rod 13. The cleaning rod 13 can push out the impurities in the liquid phase holes 6, thereby preventing them from being blocked.

[0022] The shape and size of the telescopic rod 9 are matched with the shape and size of the sleeve 8, and the telescopic rod 9 is slidably connected to the inner wall of the sleeve 8.

[0023] A screw hole is provided on one side of the bracket 7. The inner wall of the screw hole and the outer wall of the screw rod 11 are both provided with threads. The screw hole and the screw rod 11 are engaged with each other through threads. Rotating the screw rod 11 in the forward direction can drive the cleaning plate 10 to move towards the hub body 5, thereby driving the cleaning rod 13 to move synchronously, which facilitates the cleaning of the liquid phase hole 6.

[0024] A rotating shaft seat 12 is provided on one side of the cleaning plate 10, and one end of the screw 11 is rotatably connected to the rotating shaft seat 12 to facilitate the rotation of the screw 11.

[0025] Reference Figure 5-6A rotating shaft 14 is fixedly connected to the bottom of the cylinder cover 2. A screw conveyor 15 is fixedly connected to the outer wall of the rotating shaft 14. A connecting rod is fixedly connected to the outer wall of the rotating shaft 14. A scraper 16 is provided at the end of the connecting rod. During the rotation of the rotating hub body 5, the screw conveyor 15 can transport the material at the bottom of the hub body 5 to the top, making it evenly distributed, thereby improving the solid-liquid separation rate of the material. At the same time, during the rotation of the rotating hub body 5, the scraper 16 can scrape off the material remaining on the inner wall of the hub body 5, making it easy to clean the inner wall of the hub body 5.

[0026] The scraper 16 is in contact with the inner wall of the rotating hub body 5, and the scraper 16 is made of rubber material. During the rotation of the rotating hub body 5, the scraper 16 can scrape off the residual material on its inner wall, thereby facilitating the cleaning of its inner wall. Moreover, the rubber material is relatively soft and will not damage the inner wall of the rotating hub body 5.

[0027] Working principle: During use, the material is conveyed from the feed pipe 4 into the rotating body 5. When the rotating body 5 rotates, under the action of centrifugal force, the liquid phase flows out with the liquid phase hole 6, thereby realizing the solid-liquid separation of the material. During the solid-liquid separation process, the screw conveyor 15 can convey the material at the bottom of the rotating body 5 to the top, so that the material in the rotating body 5 is evenly distributed, thereby accelerating the solid-liquid separation rate. At the same time, the scraper 16 can scrape off the residual material on the inner wall of the rotating body 5 during the rotation, which is convenient for subsequent cleaning and can also prevent impurities from clogging the liquid phase hole 6. After solid-liquid separation is completed, the rotating drum body 5 rotates to the initial position and then stops. The four screws 11 are rotated in the forward direction in sequence. One end of the screw 11 pushes the cleaning plate 10 towards the rotating drum body 5, thereby driving the cleaning rod 13 on one side of the cleaning plate 10 to be inserted into the corresponding liquid phase hole 6. The cleaning rod 13 can push out the impurities inside, thus facilitating the cleaning of the rotating drum body 5 and preventing impurities from clogging the liquid phase hole 6. After cleaning is completed, the screws 11 are rotated in the reverse direction to reset the cleaning plate 10 and the cleaning rod 13.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
