Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a novel horizontal scraper discharge centrifuge. Background Technology

[0002] In the field of existing horizontal scraper discharge centrifuge technology, although these devices play a crucial role in various industries such as chemical, pharmaceutical, and food processing for efficient solid-liquid separation, their structural design and operating mechanisms still have several significant shortcomings that urgently need improvement. Specifically, traditional horizontal scraper discharge centrifuges often face the problem of cumbersome and complex disassembly and assembly processes. This is mainly due to the unreasonable design of the connection methods between various components, leading to a significant time and effort required for disassembly and reassembly during routine maintenance. Furthermore, the lack of a reliable locking mechanism between connecting parts such as the plug-in rod and the fixing block makes them prone to loosening or detachment during high-speed centrifuge rotation. This not only seriously affects the stability and operating efficiency of the equipment but may also lead to serious safety accidents, posing a potential threat to the production environment and personnel safety.

[0003] Furthermore, with the continuous advancement of technology and the acceleration of industrialization, users have placed increasingly higher demands on the ease of operation and maintainability of horizontal scraper discharge centrifuges. Traditional centrifuge designs often neglect these needs, resulting in complex and cumbersome operation, causing great inconvenience to operators. At the same time, the maintenance costs of the equipment remain high, mainly due to the complexity of the internal structure and insufficient modularity. This means that when equipment malfunctions, maintenance personnel need to spend a lot of time diagnosing and repairing it, and the process of replacing parts is often very tedious. Therefore, we provide a new type of horizontal scraper discharge centrifuge. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a novel horizontal scraper discharge centrifuge technical solution: The centrifuge mainly consists of a lower outer shell 1, a centrifuge cylinder 2, an upper outer shell 3, a rotating seat 4, a through hole 5, a sealing cover 6, and a disassembly and assembly structure. The lower outer shell 1 and the centrifuge cylinder 2 are rotatably connected by a rotating shaft. The upper outer shell 3 is fastened to the port of the lower outer shell 1. The rotating seat 4 is located at the upper center of the upper outer shell 3. The through hole 5 and the sealing cover 6 are used to seal the rotating seat 4. The disassembly and assembly structure consists of an arc-shaped block 7 on the periphery of the upper outer shell 3, a fixing block 8 on the periphery of the lower outer shell 1, a plug-in rod 9, and a plug-in groove 10, ensuring a stable connection between the upper outer shell 3 and the lower outer shell 1. During operation, the centrifuge cylinder 2 rotates at high speed under the action of the driving component to separate the materials. The design of the disassembly and assembly structure allows the upper outer shell 3 to be easily disassembled and installed, facilitating the maintenance and upkeep of the equipment.

[0024] like Figure 1-5 As shown, the anti-detachment component consists of a limiting insertion hole 11, a rectangular through slot 12, an overlapping plate 17, a limiting insertion rod 18, and a reciprocating assembly. The limiting insertion hole 11 is located on the side of the insertion rod 9, and the rectangular through slot 12 is located at the end of the fixing block 8 and communicates with the insertion slot 10. The overlapping plate 17 slides within the rectangular through slot 12, and the limiting insertion rod 18, which is fixedly connected to it, can be inserted into the limiting insertion hole 11 to prevent the insertion rod 9 from detaching from the fixing block 8. When the insertion rod 9 is inserted into the insertion slot 10, the overlapping plate 17 drives the limiting insertion rod 18 to be inserted into the limiting insertion hole 11 through the action of the reciprocating assembly, thus achieving the anti-detachment function. The addition of the anti-detachment component improves the stability and safety of the disassembly and assembly structure and avoids equipment failure caused by the accidental detachment of the insertion rod 9.

[0025] like Figure 1-5 As shown, the limiting mechanism consists of a mounting block 19, a rectangular through slot 20, a fixing plate 21, an arc-shaped limiting block 22, a pulling rod 23, and a spring 24. The mounting block 19 is fixedly mounted on the upper surface of the upper outer shell 3, the rectangular through slot 20 is formed through the mounting block 19, and the fixing plate 21 is fixed to the inner wall of the rectangular through slot 20. The arc-shaped limiting block 22 slides within the rectangular through groove 20 and is connected to the fixed plate 21 via the actuating rod 23. The spring 24 is sleeved on the actuating rod 23, providing a restoring force for the arc-shaped limiting block 22. When the sealing cover 6 is closed, the arc-shaped limiting block 22 is engaged in the limiting groove on the sealing cover 6 under the action of the spring 24, thus achieving the limiting function. When it is necessary to open the sealing cover 6, simply pull the actuating rod 23 to disengage the arc-shaped limiting block 22 from the limiting groove. The design of the limiting mechanism ensures the stability of the sealing cover 6 in the closed state and prevents equipment failure caused by misoperation.

[0026] like Figure 1-5 As shown, the reciprocating assembly consists of a strip-shaped mounting groove 13, a horizontal fixing rod 14, a spring 15, and a sliding sleeve 16. The strip-shaped mounting groove 13 is formed on the inner wall of the rectangular through groove 12. The horizontal fixing rod 14 is fixedly connected between the two end walls of the strip-shaped mounting groove 13, and the spring 15 is sleeved on the horizontal fixing rod 14. The sliding sleeve 16 is slidably sleeved on the horizontal fixing rod 14 and fixedly connected to the overlapping plate 17. When the insertion rod 9 is inserted into the insertion groove 10, the sliding sleeve 16, under the action of the spring 15, drives the overlapping plate 17 to move, so that the limiting insertion rod 18 is inserted into the limiting insertion hole 11. When disassembly is required, it is only necessary to overcome the elastic force of the spring 15 to make the sliding sleeve 16 and the overlapping plate 17 move in opposite directions. The design of the reciprocating assembly enables the anti-detachment assembly to automatically realize the limiting and unlocking functions, improving the ease of operation of the equipment.

[0027] like Figure 1-5 As shown, the drive unit consists of a drive motor 25, a first pulley 26, a second pulley 27, and a linkage belt 28. The drive motor 25 is fixedly installed on the periphery of the lower outer casing 1, and its output end is fixedly connected to the first pulley 26. The second pulley 27 is fixedly installed on the lower end of the rotating shaft and is connected to the first pulley 26 via the linkage belt 28. When the drive motor 25 starts, it drives the rotating shaft and the centrifuge drum 2 to rotate at high speed through the transmission action of the first pulley 26, the linkage belt 28, and the second pulley 27. The design of the drive unit provides a stable power source for the centrifuge drum 2, ensuring the normal operation of the equipment.

[0028] like Figure 1-5As shown, the sliding sleeve 16 is slidably connected to the inner wall of the strip-shaped placement groove 13, ensuring its stable sliding on the horizontal fixing rod 14. At the same time, the opposite surfaces of the two sliding sleeves 16 are fixedly connected to the two side surfaces of the overlapping plate 17, realizing the smooth movement of the overlapping plate 17. When the insertion rod 9 is inserted into the insertion groove 10, the sliding sleeve 16 slides along the strip-shaped placement groove 13 under the action of the spring 15, driving the overlapping plate 17 and the limiting insertion rod 18 to move to the limiting insertion hole 11 and realize the insertion. The stable connection between the sliding sleeve 16 and the strip-shaped placement groove 13 ensures the reliable operation of the anti-detachment component.

[0029] like Figure 1-5 As shown, one end of spring 24 is fixedly connected to one end surface of the arc-shaped limiting block 22, and the other end is fixedly connected to the surface of the fixing plate 21 opposite to the end of the arc-shaped limiting block 22. This connection method ensures that spring 24 can provide a stable restoring force for the arc-shaped limiting block 22. When the sealing cover 6 is closed, the arc-shaped limiting block 22 is engaged in the limiting groove under the action of spring 24. When it is necessary to open the sealing cover 6, the pulling rod 23 is pulled to overcome the elastic force of spring 24, causing the arc-shaped limiting block 22 to disengage from the limiting groove. The stable connection of spring 24 ensures the reliable operation of the limiting mechanism and improves the ease of operation and safety of the equipment.

[0030] The working principle of this utility model is as follows: First, the main structure of the centrifuge consists of a lower outer shell 1 and a centrifuge cylinder 2. The centrifuge cylinder 2 is rotatably connected to the bottom center of the lower outer shell 1 via a rotating shaft. An upper outer shell 3 is fastened to the port of the lower outer shell 1, and the two are stably connected through a disassembly and assembly structure.

[0031] The disassembly and assembly structure specifically includes an arc-shaped block 7 fixedly welded to the periphery of the upper outer shell 3 and a fixing block 8 fixedly welded to the periphery of the lower outer shell 1. The insertion rod 9 at the lower end of the arc-shaped block 7 can be inserted into the insertion slot 10 of the fixing block 8, and the insertion rod 9 is prevented from detaching from the fixing block 8 by an anti-detachment component.

[0032] The working principle of the anti-detachment component is as follows: when the plug rod 9 is fully inserted into the plug groove 10, the interaction between the reciprocating component, i.e., the spring 15 and the sliding sleeve block 16, pushes the limiting plug rod 18 on the overlapping plate 17 into the limiting plug hole 11 of the plug rod 9 to achieve a stable lock; a rotating seat 4 is provided at the upper center of the upper outer shell 3, and a sealing cover 6 is fixedly installed through the through hole 5 to seal the rotating seat 4;

[0033] In order to limit the flipping of the sealing cover 6, a limiting mechanism is provided on the upper outer shell 3. The working principle of the limiting mechanism is: when the sealing cover 6 is in the closed state, the arc-shaped limiting block 22 is pressed against and restricts the flipping of the sealing cover 6 under the action of the spring 24. The lever 23 is used to manually adjust the position of the arc-shaped limiting block 22 so as to open or close the sealing cover 6.

[0034] Power is transmitted between the lower outer casing 1 and the rotating shaft via a drive component. The working principle of the drive component is as follows: the drive motor 25 drives the second belt pulley 27 to rotate via the first belt pulley 26 and the linkage belt 28, thereby driving the rotating shaft and the centrifuge drum 2 to rotate. When the centrifuge is working, the material enters the centrifuge drum 2 through the rotating seat 4 and the sealing cover door 6, and solid-liquid separation is achieved under the action of centrifugal force. After completion, the upper outer casing 3 and the sealing cover door 6 can be easily opened by operating the disassembly and assembly structure and the limiting mechanism for unloading and maintenance.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
