A flat blade scraper centrifuge transmission mechanism

Abstract

This utility model discloses a transmission mechanism for a flat scraper unloading centrifuge, including a top cover. A base is rotatably connected to one side of the top cover, and a drive assembly is connected to the base. The drive assembly includes a cylinder, a piston rod, and a scraper. A cleaning assembly is located at the bottom end of the base outside the piston rod. The cleaning assembly includes a fixed cylinder fixed to the bottom end of the base, and multiple sets of telescopic springs are vertically distributed inside the fixed cylinder. By setting up the cleaning assembly, during use, the cleaning plate at one end of the telescopic spring can contact the outside of the piston rod through the reaction force of the telescopic spring. When the piston rod retracts into the cylinder, the multiple sets of vertically distributed cleaning plates clean the impurities adhering to the surface of the piston rod, thereby preventing impurities from entering the cylinder and affecting its operation. At the same time, the fixed cylinder can protect the outside of the piston rod and reduce the adhesion of impurities.

Description

Technical Field

[0001] This utility model relates to the technical field of flat scraper unloading centrifuges, and in particular to a transmission mechanism for a flat scraper unloading centrifuge. Background Technology

[0002] The flat scraper centrifuge is a commonly used device for separating solids and liquids, particularly suitable for processing high-concentration slurries and suspensions. Its working principle involves using the centrifugal force of high-speed rotation to separate the solids and liquids in the material, and then the separated solids are discharged by a flat scraper. This equipment is widely used in industries such as chemical, food, pharmaceutical, and mining.

[0003] In existing flat scraper centrifuges, the scraper is rotated by the transmission mechanism and vertically raised and lowered inside the centrifuge to scrape off the material adhering to the inner wall. However, impurities generated during the scraping process tend to adhere to the piston rod in the transmission mechanism. If there are many impurities on the piston rod, they can easily enter the cylinder when the piston rod retracts into the cylinder, affecting the operation of the cylinder. Utility Model Content

[0020] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0021] like Figures 1-3As shown in the figure, the transmission mechanism of the flat scraper unloading centrifuge provided in this embodiment includes a top cover 1, a base 2 rotatably connected to one side of the top cover 1, the base 2 can drive the drive assembly 3 to rotate, the drive assembly 3 is connected to the base 2, the drive assembly 3 includes a cylinder 301, a piston rod 302 and a scraper 303, a cleaning assembly 4 is provided at the bottom end of the base 2 outside the piston rod 302, the cleaning assembly 4 includes a fixed cylinder 401 fixed to the bottom end of the base 2, the fixed cylinder 401 can support one end of the telescopic spring 402, multiple sets of telescopic springs 402 are vertically distributed inside the fixed cylinder 401, the reaction force applied by the telescopic springs 402 can make the cleaning plate 403 abut against the outside of the piston rod 302, and the telescopic springs 402 are staggered in the vertical plane, the cleaning plate 403 is installed at one end of the telescopic spring 402, the cleaning plate 403 can clean the surface of the piston rod 302 and the cleaning plate 403 has an arc-shaped structure.

[0022] like Figures 1-2 As shown, cylinder 301 is fixed to the top of base 2, and piston rod 302 passes through base 2, which facilitates cylinder 301 to drive piston rod 302 to move vertically up and down. At the same time, base 2 drives cylinder 301 and piston rod 302 to rotate, thereby driving scraper 303 to rotate.

[0023] like Figures 1-2 As shown, a transmission assembly 5 is provided on the outside of the base 2. The transmission assembly 5 includes a gear ring 501, a gear 502, a connecting shaft 503 and a stepper motor 504, which facilitates the rotation of the base 2 through the transmission assembly 5.

[0024] like Figures 1-2 As shown, the gear ring 501 is fixed on the base 2, and the gear 502 meshes with the gear ring 501, enabling the gear 502 to drive the base 2 to rotate through the gear ring 501.

[0025] like Figures 1-2 As shown, gear 502 is fixedly connected to connecting shaft 503, and the output end of stepper motor 504 is connected to connecting shaft 503, so that the motor can drive gear 502 to rotate through connecting shaft 503.

[0026] like Figures 1-2 As shown, a support frame 6 is installed on one side of the top of the top cover 1, and the stepper motor 504 is fixed on the top of the support frame 6, so that the stepper motor 504 can be supported by the support frame 6.

[0027] like Figures 1-2 As shown, the top cover 1 has a sliding groove for mounting the base 2, which facilitates the horizontal rotation of the base 2 along the top cover 1.

[0028] The working principle of this device is as follows: During actual use, after the centrifuge drum inside the centrifuge centrifuge processes the material, the stepper motor 504 at the top of the support frame 6 drives the gear 502 to rotate via the connecting shaft 503. The gear 502 drives the base 2 to rotate via the gear ring 501. The base 2 then drives the cylinder 301 and piston rod 302 to rotate, which in turn drives the scraper 303 to rotate. The scraper 303 contacts and scrapes off impurities adhering to the centrifuge drum. During the scraping process, the cylinder 301 drives the piston rod 302 to move vertically up and down, thereby driving the scraper 303... 03. Vertical lifting and lowering allows for a thorough cleaning of the inner wall of the separation tank. During the lifting and lowering of the piston rod 302, the cleaning plate 403 at one end of the telescopic spring 402 contacts the outer side of the piston rod 302 through the reaction force of the telescopic spring 402. When the piston rod 302 retracts into the cylinder 301, multiple vertically distributed cleaning plates 403 clean the impurities adhering to the surface of the piston rod 302, thereby preventing impurities from entering the cylinder 301 and affecting its use. At the same time, the fixed cylinder 401 can protect the outer side of the piston rod 302 and reduce the adhesion of impurities.

Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
