Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to an oil sludge vacuum disc dryer. Background Technology

[0002] Industrial activities such as oil extraction generate large amounts of oily sludge, which needs to be processed to separate crude oil, sludge, and other substances. Vacuum disc dryers are used in this process. Vacuum disc dryers are a type of highly efficient continuous vacuum drying equipment. They indirectly heat the material by conveying a heat medium into the dryer's cylinder jacket, central shaft, and disc cavity. The material is turned and stirred by the lifting plates on the disc, constantly renewing the heating surface, thereby achieving the drying of the material.

[0003] Chinese utility model patent CN218645891U discloses a single-shaft vacuum disc dryer, including a machine body. A feed hopper is fixedly connected to one side of the top of the machine body. A filter screen is fixedly installed inside the feed hopper. A pressure roller is installed at the top of the filter screen. Both sides of the pressure roller are rotatably connected to a first slider through a rotating shaft. The two first sliders are respectively slidably installed in two first grooves.

[0004] When this technical solution is used, it mainly relies on the filter screen to filter the material and collect and process the agglomerated material. However, this will greatly slow down the falling speed of the material, resulting in a decrease in the feeding speed. In addition, it relies on the horizontally moving pressure roller to crush the agglomerated material. For larger agglomerated materials, it is difficult to crush them all in time, resulting in poor crushing effect. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a vacuum disc dryer for oily sludge.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: a vacuum disc dryer for oil sludge, comprising a dryer body, a feeding assembly, a drive mechanism, a dispersing assembly, and a scraping mechanism. The feeding assembly is installed on the upper side of the feed inlet of the dryer body, the drive mechanism is fixedly installed inside the feeding assembly, the dispersing assembly is installed on the drive mechanism, and there are two dispersing assemblies spaced apart along the material flow direction. The scraping mechanism is installed inside the feeding assembly, and the scraping part of the scraping mechanism is arranged around the dispersing assembly.

[0007] Furthermore, the feeding assembly includes a processing chamber and a feeding pipe. The processing chamber is a hollow spherical shell and is fixedly installed on the dryer body. The bottom of the processing chamber is connected to the feed inlet. The feeding pipe is located at the top of the processing chamber and is connected to the processing chamber. The drive mechanism and the dispersing assembly are both located inside the processing chamber. The scraping part is located inside the processing chamber and fits against the processing chamber.

[0008] Furthermore, an opening is provided on one side of the processing chamber, and a sealing door is provided on the processing chamber to close the opening. One side of the sealing door is hinged to the processing chamber, and a latch is provided between the sealing door and the processing chamber.

[0009] Furthermore, the drive mechanism includes a motor housing, on which mounting rods are fixedly installed on opposite sides. A U-shaped support plate is fixedly installed on the inner wall of the motor housing, and a first motor is fixedly installed on the U-shaped support plate. A first rotating shaft is fixedly connected to the output end of the first motor, and a drive gear is fixedly sleeved on the first rotating shaft. The free end of the first rotating shaft is rotatably connected to the motor housing.

[0010] Furthermore, the dispersing component includes a second rotating shaft, which is rotatable on the motor housing. One end of the second rotating shaft is fixedly mounted with a dispersing rod, and the other end of the second rotating shaft is rotatably extended into the motor housing and fixedly connected to the driven gear inside the motor housing. The driving gear meshes with the driven gear.

[0011] Furthermore, the scraping mechanism includes a second motor, which is fixedly installed on the front side of the feeding assembly. The output end of the second motor is fixedly connected to a third rotating shaft. The end of the third rotating shaft extends rotatably into the processing chamber and is fixedly connected to the scraping ring in the processing chamber, forming a scraping section in the processing chamber. The other side of the scraping ring is rotatably mounted on the drive mechanism through a collar.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention uses a first motor to drive a first rotating shaft to rotate. Through the transmission of components, the dispersing component rotates inside the feeding component, causing the dispersing rod to tap and disperse the material falling into the feeding component. This quickly processes materials that have clumped due to moisture or other reasons, increasing the feeding rate. Without slowing down the material's descent or reducing the feeding speed, it can promptly tap and disperse clumps of various sizes, preventing blockage at the dryer's inlet. A second motor drives a third rotating shaft to rotate, causing a scraper ring to reciprocate inside the feeding component, scraping off materials that have adhered to the inner wall of the feeding component due to the tapping and dispersing, ensuring that all materials are fed into the dryer.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0022] See attached document Figures 1-5 The oil sludge vacuum disc dryer includes a dryer body 1 and a feeding assembly 2. The feeding assembly 2 is fixedly installed at the inlet of the dryer body 1. A drive mechanism 3 is installed inside the feeding assembly 2, and a material-dispersing component 4 is installed on the surface of the drive mechanism 3. A scraping mechanism 5 is installed inside the feeding assembly 2 to scrape off the material. The feeding assembly 2 processes the material fed into the dryer body 1, making it fall into the dryer body 1 more dispersed and avoiding blockage of the inlet. The drive mechanism 3 drives the dispersing component 4 to rotate inside the feeding assembly 2, causing the dispersing component 4 to beat and disperse the material falling into the feeding assembly 2, increasing the feeding rate. The scraping mechanism 5 reciprocates inside the feeding assembly 2, scraping off the material that has adhered to the inner wall of the feeding assembly 2 due to the beating and dispersing, so that all the material can be fed into the dryer body 1.

[0023] The feeding assembly 2 includes a spherical processing chamber 201. The processing chamber 201 is fixedly installed on the upper side of the feed inlet of the dryer body 1. A feeding pipe 202 is fixedly installed on the top of the processing chamber 201. An opening is provided on one side of the processing chamber 201, and a sealing door 203 is hinged thereon. A sealing ring 204 is fixedly connected to the opening of the processing chamber 201, and the sealing ring 204 fits against the sealing door 203. A latch 205 is provided between the sealing door 203 and the processing chamber 201. After the sealing door 203 is opened, it is convenient for the staff to perform regular maintenance and repair on the drive mechanism 3, the dispersing assembly 4, and the scraping mechanism 5 inside the processing chamber 201. The sealing ring 204 ensures the sealing of the sealing door 203.

[0024] In this embodiment, the sealing door 203 is also an arc-shaped plate, and the sealing door 203 and the processing chamber 201 together form a complete sphere.

[0025] The drive mechanism 3 includes a motor housing 301. Mounting rods 302 are fixedly mounted on opposite sides of the motor housing 301. A U-shaped support plate 303 is fixedly mounted on the inner wall of one side of the motor housing 301. A first motor 304 is fixedly mounted on the U-shaped support plate 303. A first rotating shaft 305 is fixedly connected to the output end of the first motor 304. A drive gear 306 is fixedly mounted on the first rotating shaft 305, and the free end of the first rotating shaft 305 is rotatably connected to the inner wall of the motor housing 301. The first motor 304 drives the first rotating shaft 305 to rotate, which in turn drives the drive gear 306 to rotate, thereby pulling the dispersing assembly 4 to rotate.

[0026] The dispersing assembly 4 includes a second rotating shaft 401. The second rotating shaft 401 is rotatably mounted on both the upper and lower sides of the motor housing 301. A dispersing rod 402 is fixedly mounted on the side of the second rotating shaft 401. One end of the second rotating shaft 401 rotatably extends into the motor housing 301 and is fixedly connected to a driven gear 403 inside the motor housing 301. Two driven gears 403 are respectively located on both sides of the driving gear 306, and both driven gears 403 mesh with the driving gear 306. Through the transmission between the driven gears 403 and the driving gear 306, the second rotating shaft 401 drives the dispersing rod 402 to rotate.

[0027] In this embodiment, both the driving gear 306 and the driven gear 403 are bevel gears, and a packing seal is provided between the second rotating shaft 401 and the motor housing 301.

[0028] The scraping mechanism 5 includes a second motor 501. The second motor 501 is fixedly installed on one side of the feeding assembly 2. The output end of the second motor 501 is fixedly connected to a third rotating shaft 502. The third rotating shaft 502 rotatably passes through the processing chamber 201 and extends into the processing chamber 201. The third rotating shaft 502 is fixedly connected to the scraping ring 503 in the processing chamber 201. The scraping ring 503 is in contact with the inner wall of the processing chamber 201 and can move relative to each other. There are two scraping rings 503 arranged side by side and spaced apart. The end of the third rotating shaft 502 extends between the two scraping rings 503 and is fixedly connected to the corresponding side of the scraping ring 503. A collar 504 is fixedly installed on the other side of the two scraping rings 503. The collar 504 rotatably fits around the mounting rod 302 on the corresponding side. The collar 504 is coaxially arranged with the third rotating shaft 502.

[0029] The second motor 501 drives the third rotating shaft 502 to rotate, and the third rotating shaft 502 drives the scraper ring 503 to slide along the inner wall of the processing chamber 201, thereby scraping off the material attached to the inner wall of the processing chamber 201, ensuring that the material falls fully into the dryer body 1. The collar 504 makes the rotation process of the scraper ring 503 more stable. When adding material into the feeding assembly 2, the scraper ring 503 rotates to a horizontal state to avoid obstructing the feeding.

[0030] The free end of the third rotating shaft 502 is rotatably connected to the mounting rod 302 on the corresponding side. The collar 504 is rotatably connected to the mounting rod 302 on the corresponding side. The mounting rod 302 on the same side as the collar 504 is fixedly connected to the processing chamber 201 to prevent the motor box 301 from rotating inside the processing chamber 201.

[0031] In use, the operator places the solid material after solid-liquid separation of oil sludge into the processing chamber 201 through the feeding pipe 202. The first motor 304 drives the first rotating shaft 305 to rotate. Through the transmission of the drive gear 306 and the driven gear 403, the second rotating shafts 401 on the upper and lower sides of the motor housing 301 drive the dispersing rod 402 to rotate. The two sets of second rotating shafts 401 rotate in opposite directions, dispersing the solid material falling into the processing chamber 201. This disperses some of the material that has clumped due to moisture, preventing the feed inlet of the dryer body 1 from being blocked by clumps of material and affecting the feeding speed. While dispersing the material, the second motor 501 drives the third rotating shaft 502 to rotate, causing the scraper ring 503 to slide back and forth against the inner wall of the processing chamber 201, scraping off the material that has adhered to the inner wall of the processing chamber 201 due to the impact. This ensures that the material can be fully fed into the interior of the dryer body 1 for drying.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
