Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a disc unit centrifuge with a self-draining design pipeline. Background Technology

[0002] Disc centrifuges can quickly and continuously separate solids and liquids. They are a type of vertical centrifuge, with the drum mounted on the upper end of a vertical shaft and driven by an electric motor to rotate at high speed through a transmission device. Most existing centrifuges have horizontal slag outlets. During the slag discharge process, slag tends to accumulate on the inner wall of the pipe, which may cause blockage at the slag discharge point, reducing the practicality of the centrifuge and making it inconvenient for users.

[0003] Existing technologies, such as Chinese Patent Publication No. CN222551104U, disclose a disc centrifuge for easy slag removal, including a centrifuge body. The outer surface of the centrifuge body is provided with a liquid discharge pipe and a slag discharge pipe. An anti-clogging component and a cleaning component are installed on the outer surface of the centrifuge body. The anti-clogging component includes two first cylinders installed on the outer surface of the centrifuge body. The right ends of the two first cylinders are connected to a first movable plate, and a motor is installed on the right side of the first movable plate. This invention can output waste liquid and waste slag separately through the liquid discharge pipe and slag discharge pipe. Using the anti-clogging component, the motor drives the rotating rod and the spiral conveying blades to rotate, extending the spiral conveying blades into the slag discharge pipe, which assists in slag removal, allowing the waste slag inside to be discharged quickly and evenly. Accumulated waste slag is less likely to affect its operation, resulting in good performance. However, this invention uses fixed first and second rings to scrape off the waste slag from the inner wall of the pipe. When the rings enter the pipe, they directly scrape off the waste slag and push it deeper into the pipe, making it difficult to completely remove the waste slag.

[0004] To address the issue of disc centrifuges' difficulty in cleaning and removing waste residue from the pipes, which is prone to accumulating on the inner walls of the drain and slag discharge pipes, existing equipment may lack auxiliary slag removal measures, potentially leading to pipe blockage after prolonged use. Other equipment employs fixed slag removal mechanisms, which, while assisting in removal, may push the waste residue deeper into the pipe upon entry, further complicating waste removal. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing disc unit centrifuges are not convenient for cleaning and draining waste residue from the pipes, and to propose a disc unit centrifuge with a self-draining pipe design.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a disc-type unit centrifuge with a self-draining design pipeline, comprising a centrifuge body and a draining device. The draining device is disposed on the surface of the centrifuge body and includes a drive assembly, a discharge assembly, and an auxiliary assembly. The drive assembly includes a limiting groove formed on the surface of the centrifuge body, and a movable frame is slidably connected to the surface of the limiting groove. The discharge assembly includes a limiting rod fixedly connected to the surface of the movable frame, and a fixed disk fixedly connected to the surface of the limiting rod. A second motor is fixedly mounted on the surface of the movable frame, and a screw is fixedly connected to the output end of the second motor. A movable block is threadedly connected to the surface of the screw, and the movable block is slidably connected to the surface of the limiting rod. An adjusting frame is slidably connected to the inner wall of the fixed disk, and a connecting rod is rotatably connected to the surface of the adjusting frame. The connecting rod is rotatably connected to the surface of the movable block. A discharge plate is fixedly connected to the surface of the adjusting frame. The auxiliary assembly includes a telescopic rod fixedly connected to the surface of the discharge plate, and a scraper is fixedly connected to the surface of the telescopic rod.

[0007] Furthermore, a motor is fixedly mounted on the surface of the centrifuge body, and a bidirectional threaded rod is fixedly connected to the output end of the motor. The movable frame is threadedly connected to the surface of the bidirectional threaded rod.

[0008] Furthermore, the number of movable frames is two sets arranged symmetrically, and the number of limiting rods, adjusting frames, connecting rods and discharge plates is two.

[0009] Furthermore, a spring is sleeved and connected to the surface of the telescopic rod, one end of the spring is fixedly connected to the surface of the discharge plate, and the other end of the spring is fixedly connected to the surface of the scraper.

[0010] Furthermore, the surface of the adjusting frame is provided with rolling balls, which are slidably connected to the inner wall of the fixed plate.

[0011] Furthermore, a drain pipe is fixedly connected to the surface of the centrifuge body, and the scraper cooperates with the drain pipe.

[0012] Furthermore, a slag discharge pipe is fixedly connected to the surface of the centrifuge body, and the scraper cooperates with the slag discharge pipe.

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

[0014] 1. In this utility model, by setting up a discharge device, firstly, motor two is started to drive the screw to rotate, causing the movable block to move towards motor two along the limiting rod. The connecting rod drives the adjusting frame to move the discharge plate towards the fixed plate, causing the discharge plate and scraper to retract, avoiding direct contact with the inner wall of the pipe when entering the pipe and pushing the waste residue deep. Then, motor one is started to drive the bidirectional threaded rod to rotate, causing the two sets of movable frames to move towards each other and enter the liquid discharge pipe and slag discharge pipe respectively. After they have completely entered, motor two is started to reverse, causing the movable block to move away from motor two. The connecting rod drives the adjusting frame to move the discharge plate away from the fixed plate until the scraper contacts the inner wall of the pipe. Then, motor one is started to reverse, causing the two sets of movable frames to move in opposite directions. The scraper scrapes off the waste residue on the inner wall of the pipe, and the discharge plate and fixed plate push the waste residue out of the pipe.

[0015] 2. In this utility model, by setting up a draining device, the waste residue in the pipe can be cleaned and discharged, avoiding pipe blockage. Furthermore, the adjustable scraper prevents the waste residue from being pushed deeper into the pipe when it enters, thus effectively improving the convenience of the equipment.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a disc unit centrifuge with a self-draining design pipe, including a centrifuge body 1 and a draining device 4, the draining device 4 being disposed on the surface of the centrifuge body 1.

[0024] The specific setup and function of its drainage device 4 will be explained below.

[0025] In this embodiment: the draining device 4 includes a drive assembly 41, a draining assembly 42, and an auxiliary assembly 43. The drive assembly 41 includes a limiting groove 411, which is formed on the surface of the centrifuge body 1. A movable frame 412 is slidably connected to the surface of the limiting groove 411. The draining assembly 42 includes a limiting rod 421, which is fixedly connected to the surface of the movable frame 412. A fixed plate 422 is fixedly connected to the surface of the limiting rod 421. A second motor 423 is fixedly mounted on the surface of the movable frame 412. A screw is fixedly connected to the output end of the second motor 423. The surface of the rod 424 is threadedly connected to a movable block 425. The movable block 425 is slidably connected to the surface of the limiting rod 421. The inner wall of the fixed plate 422 is slidably connected to an adjusting frame 426. The surface of the adjusting frame 426 is rotatably connected to a connecting rod 427. The connecting rod 427 is rotatably connected to the surface of the movable block 425. The surface of the adjusting frame 426 is fixedly connected to a discharge plate 428. The auxiliary component 43 includes a telescopic rod 431. The telescopic rod 431 is fixedly connected to the surface of the discharge plate 428. The surface of the telescopic rod 431 is fixedly connected to a scraper 432.

[0026] The effects achieved by the above components are as follows: the starting motor 423 drives the screw 424 to rotate, which allows the movable block 425 to move along the limiting rod 421. The connecting rod 427 drives the adjusting frame 426 to move the discharge plate 428 away from or closer to the fixed plate 422, thereby realizing the adjustment of the position of the scraper 432. This avoids direct contact with the pipe when entering the pipe, which would push the waste into the depth of the pipe. The limiting groove 411 is set to prevent the movable frame 412 from rotating with the bidirectional threaded rod 414. The discharge plate 428 and the fixed plate 422 are set to facilitate the discharge of waste from the pipe. The telescopic rod 431 is set to cooperate with the spring 433. The scraper 432 is set to facilitate the scraping of waste off the inner wall of the pipe.

[0027] Specifically, a motor 413 is fixedly mounted on the surface of the centrifuge body 1, and a bidirectional threaded rod 414 is fixedly connected to the output end of the motor 413. The movable frame 412 is threadedly connected to the surface of the bidirectional threaded rod 414.

[0028] The effect achieved by the above components is as follows: the starting motor 413 drives the bidirectional threaded rod 414 to rotate, thereby causing the two sets of movable frames 412 to move towards each other or away from each other, which facilitates the cleaning of the pipeline.

[0029] Specifically, there are two sets of movable frames 412 arranged symmetrically, and two limit rods 421, adjusting frames 426, connecting rods 427 and discharge plates 428.

[0030] The effects achieved by the above components are as follows: setting two sets of movable frames 412 is to facilitate the simultaneous cleaning and drainage of the liquid discharge pipe 2 and the slag discharge pipe 3; setting two limit rods 421 is to increase structural stability; and setting two discharge plates 428 is to increase the discharge range.

[0031] Specifically, a spring 433 is sleeved and connected to the surface of the telescopic rod 431. One end of the spring 433 is fixedly connected to the surface of the discharge plate 428, and the other end of the spring 433 is fixedly connected to the surface of the scraper 432.

[0032] The effect achieved by the above components is as follows: the spring 433 is set to cooperate with the telescopic rod 431 to prevent the scraper 432 from being damaged due to hard contact with the pipe.

[0033] Specifically, the surface of the adjusting frame 426 is provided with rolling balls 434, which are slidably connected to the inner wall of the fixed plate 422.

[0034] The effect achieved by the above components is that the ball bearing 434 is set to make the movement of the adjusting bracket 426 smoother and avoid jamming.

[0035] Specifically, a drain pipe 2 is fixedly connected to the surface of the centrifuge body 1, and a scraper 432 cooperates with the drain pipe 2.

[0036] The effect achieved by the above components is that, driven by the movable frame 412, the scraper 432 can clean the waste residue remaining on the inner wall of the drain pipe 2.

[0037] Specifically, a slag discharge pipe 3 is fixedly connected to the surface of the centrifuge body 1, and a scraper 432 cooperates with the slag discharge pipe 3.

[0038] The effect achieved by the above components is that, driven by the movable frame 412, the scraper 432 can clean the waste residue remaining on the inner wall of the slag discharge pipe 3.

[0039] Working principle: By setting up the discharge device 4, firstly, motor 2 423 is started to drive screw 424 to rotate, causing movable block 425 to move along limit rod 421 towards motor 2 423. Connecting rod 427 drives adjusting frame 426 to move discharge plate 428 towards fixed plate 422, causing discharge plate 428 and scraper 432 to retract, preventing direct contact with the inner wall of the pipe and pushing waste residue deeper. Then, motor 1 413 is started to drive bidirectional threaded rod 414 to rotate, causing the two sets of movable frames 412 to face each other. Okay, the waste enters the drain pipe 2 and the slag outlet pipe 3 respectively. After it is fully entered, start motor 2 423 to reverse, so that the movable block 425 moves away from motor 2 423. The connecting rod 427 causes the adjusting frame 426 to drive the discharge plate 428 to move away from the fixed plate 422 until the scraper 432 contacts the inner wall of the pipe. Then start motor 1 413 to reverse, so that the two sets of movable frames 412 move in opposite directions. The scraper 432 scrapes the waste residue off the inner wall of the pipe, and the discharge plate 428 and the fixed plate 422 push the waste residue out of the pipe.

[0040] Furthermore, by setting up a draining device 4, the waste residue in the pipeline can be cleaned and discharged to avoid clogging the pipeline. In addition, the adjustable scraper 432 is used to prevent the waste residue from being pushed directly into a deeper part of the pipeline when it enters, which effectively improves the convenience of the equipment.
