Abstract
Description
Technical Field
[0001] This utility model belongs to the field of feed and oil processing, and in particular relates to an oil residue removal device. Background Technology
[0002] Feed oils are an important energy source in animal feed, with triglycerides as their main component, composed of glycerol and fatty acids. Feed oil processing is a comprehensive industry involving raw material handling, production processes, equipment application, and quality control.
[0003] Comparing with Chinese Patent No. CN212333692U, a long-distance drip-drying oil sludge conveyor is disclosed, including a frame, on which a conveyor body is mounted. The conveyor body includes a horizontal conveying section and an inclined conveying section connected together. Both the horizontal and inclined conveying sections are equipped with filter screen belts. The conveyor body is equipped with a drive assembly for rotating the filter screen belts. An oil receiving trough is located below the filter screen belts on the conveyor body. Multiple filter screen baffles are arranged along the length of the filter screen belts. This method has the advantage of reducing the oil content in the oil sludge during the initial filtration stage.
[0004] However, the aforementioned patented oil residue is easily adhered to the filter screen by the oil and falls into the oil receiving tank, reducing the quality of oil recovery. Therefore, a new device needs to be designed. Utility Model Content
[0005] The purpose of this invention is to provide an oil residue removal device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An oil sludge removal device includes a tank assembly for holding oil and oil sludge, and a rotary pusher assembly installed in the middle of the tank assembly for rotating and pushing the oil sludge. A scraping assembly is inclined on one side of the rotary pusher assembly for circulating, scraping, moving, lifting, and discharging the oil sludge. The tank assembly includes an inclined guide platform with symmetrically arranged limiting edges on both sides. An oil storage tank is located at the bottom of the inclined guide platform, and an oil discharge mechanism for filtering and discharging the oil is located on the side of the oil storage tank. The rotary pusher assembly includes a drive shaft with a first motor at one end and a pushing mechanism mounted on the drive shaft. The scraping assembly includes a drive roller and a support roller, with a drive belt installed between the drive roller and the support roller. A second motor is located at the end of the drive roller, and several oil-draining mechanisms for scraping and draining oil sludge are evenly distributed on the surface of the drive belt.
[0008] Furthermore: the oil outlet mechanism includes an oil outlet pipe, an oil outlet valve is installed on the oil outlet pipe, and a filter head is installed at the end of the oil outlet pipe located in the oil storage tank.
[0009] Furthermore, the inclined guide platform, the limiting edge, and the oil storage tank are integrally formed.
[0010] Furthermore: the pushing mechanism includes a connecting sleeve, and a plurality of push plates are evenly distributed around the circumference of the connecting sleeve.
[0011] Furthermore, the push plate has several oil passage holes evenly distributed in the middle.
[0012] Furthermore, the oil-draining mechanism includes a fixed frame, and an oil-draining mesh is installed in the middle of the fixed frame.
[0013] Furthermore, the oil draining mesh is made of 304 stainless steel and is riveted together with the fixing frame.
[0014] Compared with existing technologies, the beneficial effects are:
[0015] 1. The rotating pusher plate (rotating pusher assembly) pushes the oil residue to gather on the inclined guide table, while the oil draining screen (scraping assembly) on the transmission belt continuously scrapes and lifts the oil residue, forming a continuous operation cycle, which significantly improves the separation efficiency. During the upward process of the oil residue, the oil is filtered through the oil draining screen and the oil passage holes of the pusher plate, realizing oil draining while conveying, reducing the oil content of the oil residue and improving the oil recovery rate.
[0016] 2. The inclined guide platform, limiting edge and oil storage tank are integrally formed. The oil flows back to the oil storage tank along the inclined guide platform. The limiting edge prevents splashing and leakage, ensuring that the oil can be recovered in a controllable manner throughout the process. The oil draining screen (304 stainless steel) initially filters the oil residue, and the filter head at the outlet of the oil storage tank filters the oil for a second time to prevent impurities from clogging the oil outlet pipe and ensure the cleanliness of the discharged oil.
[0017] 3. The first motor (rotary pusher) and the second motor (scraper) are independently controlled, and the speed can be adjusted according to the amount of oil residue to reduce energy consumption; the oil residue is automatically lifted and discharged, and the oil is automatically returned to the filter, reducing the cost of manual cleaning and monitoring.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-6 An oil sludge removal device includes a tank assembly for holding oil and oil sludge, and a rotary pusher assembly installed in the middle of the tank assembly for rotating and pushing the oil sludge to move. A scraping assembly is inclined on one side of the rotary pusher assembly for circulating scraping, conveying, moving, raising, and discharging the oil sludge.
[0027] In this embodiment: the tank assembly includes an inclined guide platform 101, with limiting edges 103 symmetrically arranged on both sides of the inclined guide platform 101. An oil storage tank 102 is provided at the bottom of the inclined guide platform 101, and an oil discharge mechanism for filtering and discharging oil is provided on the side of the oil storage tank 102. The oil discharge mechanism includes an oil discharge pipe 104, an oil discharge valve 105 installed on the oil discharge pipe 104, and a filter head 106 installed at the end of the oil discharge pipe 104 located within the oil storage tank 102. The inclined guide platform 101, limiting edges 103, and limiting edges 103 are all provided on both sides of the inclined guide platform 101. The limiting edge 103 and the oil storage tank 102 are integrally formed; oil and oil residue are continuously poured into the oil storage tank 102. When the oil residue rises along the inclined guide platform 101, the oil drips through the oil draining screen 305 onto the inclined guide platform 101 and flows down along the inclined guide platform 101 back to the oil storage tank 102. The limiting edge 103 is used to prevent the oil on the inclined guide platform 101 from leaking out. The oil in the oil storage tank 102 passes through the filter head 106 and flows out from the oil outlet pipe 104 with the oil outlet valve 105 open.
[0028] In this embodiment: the rotary push assembly includes a drive shaft 205, one end of which is provided with a first motor 204, and a pushing mechanism is installed on the drive shaft 205; the pushing mechanism includes a connecting sleeve 201, and a plurality of push plates 202 are evenly distributed around the circumference of the connecting sleeve 201; a plurality of oil passage holes 203 are evenly distributed in the middle of the push plates 202; the first motor 204 drives the drive shaft 205 to rotate the push plates 202 through the connecting sleeve 201, pushing the oil sludge floating on the surface of the oil close to the inclined guide table 101, and the oil flows back through the oil passage holes 203 on the surface of the push plates 202;
[0029] In this embodiment: the scraping assembly includes a drive roller 302 and a support roller 301. A transmission belt 303 is installed between the drive roller 302 and the support roller 301. A second motor 306 is provided at the end of the drive roller 302. Several oil-draining mechanisms for scraping oil residue and draining oil are evenly distributed on the surface of the transmission belt 303. The oil-draining mechanism includes a fixed frame 304. An oil-draining net 305 is installed in the middle of the fixed frame 304. The oil-draining net 305 is made of 304 stainless steel and is riveted to the fixed frame 304. The second motor 306 drives the drive roller 302 to rotate, so that the transmission belt 303 moves along the inclined guide platform 101 under the support of the support roller 301. This drives the oil-draining net 305 in the fixed frame 304 to push the oil residue up along the inclined guide platform 101 and discharge it from the top of the inclined guide platform 101. The oil drips onto the inclined guide platform 101 through the oil-draining net 305.
[0030] Working principle: Oil and oil residue are continuously poured into the oil storage tank 102. The first motor 204 drives the transmission shaft 205 to rotate the push plate 202 through the connecting sleeve 201, pushing the oil residue floating on the surface of the oil closer to the inclined guide table 101. The oil then flows back through the oil passage hole 203 on the surface of the push plate 202. At the same time, the second motor 306 drives the drive roller 302 to rotate, so that the transmission belt 303 moves along the inclined guide table 101 under the support of the support roller 301. This causes the oil draining screen 305 in the fixed frame 304 to push the oil residue up along the inclined guide table 101 and discharge it from the top of the inclined guide table 101. The oil drips onto the inclined guide table 101 through the oil draining screen 305 and flows down the inclined guide table 101 back to the oil storage tank 102. The oil in the oil storage tank 102 then flows out through the filter head 106 and the oil outlet pipe 104 with the oil outlet valve 105 open.
