Description

Technical Field

[0001] This utility model relates to the field of waste oil treatment devices, specifically a waste oil washing and filtering device. Background Technology

[0002] Waste grease flushing and filtration devices are equipment used to treat waste paint and grease, thereby reducing environmental impact and ensuring safe disposal. These devices are widely used in industry, catering, and other fields that generate large amounts of waste grease.

[0003] However, current treatment devices still have some shortcomings. For example, patent application CN202322683501.1 discloses a waste oil washing and filtering device. It filters particles or residues in sewage through a filter plate, and then filters oil through a hydrophilic and oleophobic membrane. By gradually filtering particulate impurities and oil in the wastewater, the filtration effect of this device is improved, solving the problem that current devices are not convenient for filtering particulate impurities in washing wastewater, which affects the sewage treatment effect. However, the disassembly and assembly steps of its filter mechanism are relatively cumbersome, which means that when the staff needs to clean the filter plate or replace the hydrophilic and oleophobic membrane, it takes a long time to disassemble and assemble, which interferes with the efficiency of the staff's regular maintenance and has certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structure to provide a waste oil washing and filtering device. Utility Model Content

[0005] The purpose of this invention is to provide a waste oil washing and filtering device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste oil rinsing and filtering device, comprising a support bracket and a flow guide shell. A conveying mechanism is installed inside the support bracket, and a protective cover is fixedly installed on the top of the support bracket. A water supply pipe is fixedly connected to the top of the protective cover, and a spray rinsing assembly is fixedly installed at the end of the water supply pipe. The flow guide shell is fixedly installed at the bottom of the support bracket, and a coarse filter assembly is movably connected to the inner surface of the flow guide shell. A heating water tank is fixedly installed at the bottom of the flow guide shell, and a fine filter assembly is movably installed at equal intervals inside the heating water tank. Support columns are symmetrically installed on the top of the heating water tank.

[0007] Furthermore, the spray flushing assembly includes a hollow connecting chamber, flushing nozzles, and fixing rods. The bottom of the hollow connecting chamber is equipped with flushing nozzles arranged in an array at equal intervals, and the top of the hollow connecting chamber is symmetrically equipped with fixing rods. The top of the hollow connecting chamber is fixedly connected to the end of the water supply pipe.

[0008] Furthermore, the top of the hollow connecting compartment is fixedly connected to the bottom of the fixing rod, and the top of the fixing rod is fixedly connected to the top inner surface of the protective cover. The hollow connecting compartment and the protective cover form a fixed structure through the fixing rod.

[0009] Furthermore, the coarse filter assembly includes an impurity carrier box, a handle, a coarse filter screen, and T-shaped slide bars. The handle is fixedly installed on the outer surface of the impurity carrier box, and the coarse filter screen is embedded in the bottom of the impurity carrier box. T-shaped slide bars are symmetrically installed on both sides of the impurity carrier box.

[0010] Furthermore, the side of the impurity carrier box is fixedly connected to the inner side of the T-shaped slide bar, and the impurity carrier box forms a sliding structure with the flow guide shell through the T-shaped slide bar.

[0011] Furthermore, the fine filter assembly includes a fine filter screen, guide rails, a hydrophilic and oleophobic membrane, and a sealing plate. Guide rails are symmetrically installed on both sides of the fine filter screen, and hydrophilic and oleophobic membranes are symmetrically attached to the upper and lower sides of the fine filter screen. A sealing plate is fixedly installed on the outer side of the fine filter screen.

[0012] Furthermore, the side of the fine filter screen is fixedly connected to the inner side of the guide slide, and the fine filter screen forms a sliding structure with the heating water tank through the guide slide.

[0013] Furthermore, the bottom of the support column is fixedly connected to the top of the heating water tank, and the top of the support column is fixedly connected to the bottom of the bearing bracket, and the bearing bracket forms a fixed structure with the heating water tank through the support column.

[0014] This utility model provides a waste oil flushing and filtering device, which has the following beneficial effects:

[0015] 1. This utility model, through the arrangement of coarse and fine filter components, enables the device to have multiple filtration functions, thereby improving the filtration effect of the wastewater. This allows the water returning to the heating water tank to undergo repeated rinsing, thus improving the water resource utilization rate of the device. Furthermore, when the coarse filter component performs initial filtration, it can filter out small impurities such as particles in waste oil, thereby greatly reducing the filtration pressure of the fine filter component and improving its filtration efficiency to a certain extent (i.e., reducing the probability of clogging of the fine filter component), thus making the processing efficiency of this rinsing and filtration device better.

[0016] 2. This utility model, through the design of the T-shaped sliding strip, allows the coarse filter assembly to be quickly removed from the inside of the guide housing by the operator, thus providing convenience for the operator to clean the impurities filtered by the coarse filter assembly. Furthermore, the design of the guide sliding strip allows the fine filter assembly to be quickly removed from the inside of the heating water tank by the operator, thus providing convenience for the operator to replace the hydrophilic and oleophobic membrane or clean the fine filter screen. This avoids the situation where the operator needs to spend a long time disassembling and assembling the filter plate to clean it or replace the hydrophilic and oleophobic membrane, which would interfere with the operator's regular maintenance efficiency. Moreover, the design of the sealing plate ensures that water will not flow out from the fine filter assembly when it is used for filtration after installation. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-3As shown, a waste oil rinsing and filtering device includes a support bracket 1 and a guide shell 6. A conveying mechanism 2 is installed inside the support bracket 1, and a protective cover 3 is fixedly installed on the top of the support bracket 1. A water supply pipe 4 is fixedly connected to the top of the protective cover 3, and a spray rinsing assembly 5 is fixedly installed at the end of the water supply pipe 4. The spray rinsing assembly 5 includes a hollow connecting chamber 51, rinsing nozzles 52, and fixing rods 53. The bottom of the hollow connecting chamber 51 is equipped with rinsing nozzles 52 arranged in an array at equal intervals, and the top of the hollow connecting chamber 51 is symmetrically equipped with fixing rods 53. The top of the hollow connecting chamber 51 is fixedly connected to the bottom of the fixing rods 53, and the top of the fixing rods 53 is fixedly connected to the inner surface of the top of the protective cover 3. The hollow connecting chamber 51 and the protective cover 3 form a fixed structure through the fixing rods 53. The hollow connecting chamber 51 and the protective cover 3 prevent the hollow connecting chamber 51 from loosening when carrying hot water. The top of the hollow connecting chamber 51 is fixedly connected to the end of the water supply pipe 4. The flow guide shell 6 is fixedly installed at the bottom of the support bracket 1, and the inner surface of the flow guide shell 6 is movably connected to the coarse filter assembly 7. The bottom of the flow guide shell 6 is fixedly installed with the heating water tank 8, and the interior of the heating water tank 8 is equidistantly installed with the fine filter assembly 9. At the same time, the top of the heating water tank 8 is symmetrically installed with the support columns 10, the bottom of the support columns 10 is fixedly connected to the top of the heating water tank 8, and the top of the support columns 10 is fixedly connected to the bottom of the support bracket 1. The support bracket 1 and the heating water tank 8 form a fixed structure through the support columns 10. By setting the support bracket 1 and the heating water tank 8 into a fixed structure, the support bracket 1 is more stable when the conveying mechanism 2 is running.

[0023] like Figure 1 and Figure 2As shown, the flow guide housing 6 is fixedly installed at the bottom of the support bracket 1, and a coarse filter assembly 7 is movably connected to the inner surface of the flow guide housing 6. The coarse filter assembly 7 includes an impurity carrying box 71, a handle 72, a coarse filter screen 73, and a T-shaped slide bar 74. The handle 72 is fixedly installed on the outer surface of the impurity carrying box 71, and the coarse filter screen 73 is embedded in the bottom of the impurity carrying box 71. T-shaped slide bars 74 are symmetrically installed on both sides of the impurity carrying box 71. The sides of the impurity carrying box 71 are fixedly connected to the inner sides of the T-shaped slide bars 74, and the impurity carrying box 71 forms a sliding structure with the flow guide housing 6 through the T-shaped slide bars 74. By configuring the impurity carrying box 71 and the flow guide housing 6 with a sliding structure, the impurity carrying box 71 moves more smoothly and stably back and forth along the inner surface of the flow guide housing 6. A heating water tank 8 is fixedly installed at the bottom, and a fine filter assembly 9 is movably installed at equal intervals inside the heating water tank 8. The fine filter assembly 9 includes a fine filter screen 91, guide rails 92, a hydrophilic and oleophobic membrane 93, and a sealing plate 94. Guide rails 92 are symmetrically installed on both sides of the fine filter screen 91, and the sides of the fine filter screen 91 are fixedly connected to the inner sides of the guide rails 92. The fine filter screen 91 and the heating water tank 8 form a sliding structure through the guide rails 92. By setting the fine filter screen 91 and the heating water tank 8 into a sliding structure, the fine filter screen 91 moves more smoothly and stably when it moves back and forth along the inner surface of the heating water tank 8. The hydrophilic and oleophobic membrane 93 is symmetrically attached to the upper and lower sides of the fine filter screen 91, and a sealing plate 94 is fixedly installed on the outer side of the fine filter screen 91. At the same time, support columns 10 are symmetrically installed on the top of the heating water tank 8.

[0024] In summary, this waste grease washing and filtering device firstly... Figures 1 to 3As shown in the diagram, the operator activates the heating element in the heating water tank 8 via a controller to heat the water. Then, the controller activates the conveying mechanism 2 and the water pump. When the conveying mechanism 2 starts running, it transports the waste oil from the animals and plants to be rinsed into the protective cover 3. When the water pump starts running, it transports the hot water from the heating water tank 8 into the hollow connecting chamber 51. Then, with the assistance of the rinsing nozzles 52, the hot water is evenly sprayed onto the top of the conveying mechanism 2, achieving efficient rinsing of the waste oil. The rinsing wastewater then enters the guide housing 6 through the drain port at the bottom of the support bracket 1. At this point, the wastewater undergoes initial filtration through the coarse filter 73. The pre-filtered wastewater then enters the heating water tank 8 through the guide housing 6, where it passes through two sets of fine filters 91 and a hydrophilic-oleophobic membrane 93. The wastewater is further finely filtered to improve the filtration effect of the device. The filtered water is automatically stored in the heating water tank 8 for heating and subsequent rinsing. When the device needs to be maintained, the operator grasps the handle 72 and slides the T-shaped slide bar 74 to pull the impurity carrier box 71 out of the guide housing 6. Then, the impurities collected in the impurity carrier box 71 are poured into the recycling point and rinsed. The rinsed coarse filter assembly 7 is then reinstalled into the guide housing 6 for subsequent filtration. Next, the operator grasps the handle on the outside of the sealing plate 94 and slides the guide slide bar 92 to remove it from the heating water tank 8. Then, the operator replaces the hydrophilic and oleophobic membrane 93 and rinses the fine filter screen 91. After the fine filter assembly 9 is cleaned, it is reinstalled into the heating water tank 8 for subsequent filtration.
