Description

Technical Field

[0001] This utility model relates to the field of kitchen waste oil recycling technology, and in particular to a kitchen waste oil recycling pump. Background Technology

[0002] Waste cooking oil refers to waste cooking oil generated during the catering process. This type of oil usually comes from cooking methods such as frying, deep-frying, and stir-frying. It contains high levels of fat, and improper handling can pollute the environment and potentially cause hygiene problems. Therefore, it is necessary to recycle waste cooking oil. This not only reduces environmental pollution but also effectively develops renewable resources. Currently, waste cooking oil recycling requires the use of extraction pumps, typically screw pumps. Screw pumps can stably pump high-viscosity fluids, including waste cooking oil. This efficient method of movement can effectively reduce extraction time and improve work efficiency, but there are still problems that need to be solved.

[0003] Waste oil contains food residue, such as oil residue and bone fragments. If these residues enter the extraction pump directly, they will increase the wear of internal pump components (such as rotor and stator), shorten the pump's service life, and may cause blockages in the pump body or pipelines, thereby affecting normal extraction and flow, impacting the normal operation of the equipment, increasing the frequency of maintenance, requiring multiple shutdowns for maintenance, and reducing work efficiency. Therefore, it is necessary to design a waste oil recovery pump to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste oil recovery pump for kitchen waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste cooking oil recovery pump includes a screw pump. Four positioning rods are fixedly connected to the input end of the screw pump. Each of the four positioning rods is fitted with the same fixed sleeve. The fixed sleeve has four positioning holes that mate with the positioning rods. A filter cartridge is fixedly connected to the inner wall of the fixed sleeve. The filter cartridge has several filter holes. The positioning rods have slots and circular grooves that communicate with each other. A baffle is installed in the slot, and a circular plate is installed in the circular groove. The baffle is fixedly connected to the circular plate. A pull rod is fixedly connected to the top of the circular plate, and a spring is fitted onto the pull rod. A sliding groove is installed on the fixed sleeve, and a slider is installed in the sliding groove. The slider is slidably connected to the fixed sleeve. A knob is fixedly connected to the top of the sliding groove, and four fixing rods are fixedly connected to the inner wall of the knob. Each of the four fixing rods is fixedly connected to a locking block. Because a filter cartridge is used to filter residue... This technology effectively prevents residue from entering the screw pump. The quick-release mechanism for installing the filter cartridge facilitates easy disassembly and deep cleaning. It effectively addresses the issue raised in the background technology that waste oil contains food residue, such as oil sludge and bone fragments. If these residues directly enter the pump, they increase wear on internal components (such as the rotor and stator), shorten the pump's lifespan, and may cause blockages in the pump body or pipelines, affecting normal extraction and flow, impacting equipment operation, increasing maintenance frequency, requiring multiple shutdowns for maintenance, and reducing work efficiency. This technology ensures stable operation of the screw pump, guarantees normal waste oil recovery, maintains recovery efficiency, effectively blocks residue, extends the screw pump's lifespan, and is simple to operate, facilitating filter cartridge installation and disassembly and reducing the difficulty of deep cleaning the filter cartridge.

[0007] Preferably, a flange is provided at the top of the input end of the screw pump, and a connecting pipe is fixedly connected to the top of the flange.

[0008] Preferably, a flexible tube is fixedly connected to the inner wall of the connecting pipe.

[0009] Preferably, a fixing frame is fixedly connected to the inner wall of the connecting pipe, and a rotating shaft is slidably connected to the inner wall of the fixing frame.

[0010] Preferably, a turbine is fixedly connected to the top of the rotating shaft, and a fixed shaft is fixedly connected to the bottom of the rotating shaft. Scrapers are fixedly connected to the bottom of both ends of the fixed shaft. Since the technology that allows the scraper to move along the outer wall of the filter cartridge during the extraction of waste oil is adopted, the bristles on the scraper can brush the filter cartridge when the scraper moves, cleaning away some of the residue, preventing the residue from accumulating on the filter cartridge and causing the filter holes to be covered, ensuring that the filtration work can be carried out stably and ensuring work efficiency.

[0011] Preferably, the scraper has bristles on the side near the filter cartridge.

[0012] Preferably, the bristles on the scraper are in contact with the outer wall of the filter cartridge.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By employing a filter cartridge to filter residue, this technology effectively prevents residue from entering the screw pump. The quick-release mechanism for installing the filter cartridge facilitates easy disassembly and deep cleaning. This effectively addresses the issue raised in the background technology that waste oil contains food residue, such as oil sludge and bone fragments. If these residues directly enter the pump, they increase wear on internal components (such as the rotor and stator), shorten the pump's lifespan, and may cause blockages in the pump body or pipelines, affecting normal extraction and flow, impacting equipment operation, increasing maintenance frequency, requiring multiple shutdowns for maintenance, and reducing work efficiency. This technology ensures stable operation of the screw pump, guarantees normal waste oil recovery, maintains recovery efficiency, effectively blocks residue, extends the screw pump's lifespan, and offers simple operation, easy installation and disassembly of the filter cartridge, and reduces the difficulty of deep cleaning the filter cartridge.

[0015] 2. Because the technology that allows the scraper to move along the outer wall of the filter cartridge during the waste oil extraction process is adopted, the bristles on the scraper can brush the filter cartridge when the scraper moves, cleaning away some of the residue and preventing the residue from accumulating on the filter cartridge and covering the filter holes, thus ensuring stable filtration and high work efficiency.

[0024] 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.

[0025] Reference Figure 1-7A waste cooking oil recycling pump includes a screw pump 1. Four positioning rods 2 are fixedly connected to the input end of the screw pump 1. Each of the four positioning rods 2 is fitted with the same fixing sleeve 3. The fixing sleeve 3 has four positioning holes 4. The positioning rods 2 and the positioning holes 4 cooperate to position the fixing sleeve 3. The positioning holes 4 are adapted to the positioning rods 2. A filter cartridge 5 is fixedly connected to the inner wall of the fixing sleeve 3. The filter cartridge 5 has several filter holes 6. The positioning rods 2 have slots 7 and circular grooves. 8. Slot 7 and circular groove 8 are connected. Slot 7 is equipped with a baffle 9, and circular groove 8 is equipped with a circular plate 10. Baffle 9 is fixedly connected to circular plate 10. A pull rod 11 is fixedly connected to the top of circular plate 10. A spring 12 is sleeved on pull rod 11. A sliding groove 13 is opened on fixed sleeve 3. A slider 14 is installed in sliding groove 13. Sliding slider 14 is slidably connected to fixed sleeve 3. A knob 17 is fixedly connected to the top of sliding groove 13. Four fixing rods 15 are fixedly connected to the inner wall of knob 17. All components are fixedly connected with locking blocks 16. Due to the use of filter cartridges to filter residues, it effectively prevents residues from entering the screw pump. The filter cartridges are installed via a quick-release mechanism, facilitating later disassembly and deep cleaning. This effectively solves the problem mentioned in the background technology that waste oil contains food residues, such as oil sludge and bone fragments. If these residues directly enter the pump, they will increase the wear of internal components such as the rotor and stator, shorten the pump's lifespan, and may cause blockages in the pump body or pipelines, thus affecting normal extraction and flow, impacting the normal operation of the equipment, increasing the frequency of maintenance, requiring multiple shutdowns for maintenance, and reducing work efficiency. Therefore, this technology ensures stable operation of the screw pump, guarantees normal waste oil recovery, ensures the efficiency of the recovery work, effectively blocks residues, extends the service life of the screw pump, and is simple to operate, facilitating the installation and disassembly of the filter cartridges and reducing the difficulty of deep cleaning the filter cartridges.

[0026] In this utility model, a flange 18 is provided at the top of the input end of the screw pump 1. The flange 18 and the input end of the screw pump 1 are fixedly connected by bolts, and a connecting pipe 19 is fixedly connected to the top of the flange 18.

[0027] In this utility model, a flexible hose 20 is fixedly connected to the inner wall of the connecting pipe 19.

[0028] In this utility model, a fixing frame 21 is fixedly connected to the inner wall of the connecting pipe 19, and a rotating shaft 22 is slidably connected to the inner wall of the fixing frame 21.

[0029] In this invention, a turbine 23 is fixedly connected to the top of the rotating shaft 22, and a fixed shaft 24 is fixedly connected to the bottom of the rotating shaft 22. Scrapers 25 are fixedly connected to the bottom of both ends of the fixed shaft 24. The extracted waste oil impacts the turbine 23, causing the turbine 23 to rotate, providing power to move the scraper 25 along the outer wall of the filter cartridge 5 for cleaning. Because the technology of moving the scraper along the outer wall of the filter cartridge during the extraction of waste oil is adopted, the bristles on the scraper can brush the filter cartridge when the scraper moves, cleaning away some of the residue, preventing the residue from accumulating on the filter cartridge and causing the filter holes to be covered, ensuring that the filtration work can be carried out stably and ensuring work efficiency.

[0030] In this invention, the scraper 25 is provided with bristles on the side near the filter cartridge 5. The scraper 25 moves so that the bristles on the scraper 25 can brush and clean the filter cartridge 5.

[0031] In this invention, the bristles on the scraper 25 are in contact with the outer wall of the filter cartridge 5.

[0032] Working Principle: During use, start the drive motor of screw pump 1, insert hose 20 into the waste oil storage container, and begin waste oil extraction. The waste oil is extracted through hose 20 into connecting pipe 19, then through filter holes 6 into the input end of screw pump 1, and finally discharged through the output end of screw pump 1. A pipe is connected to the output end of screw pump 1. During waste oil extraction, the waste oil impacts turbine 23, causing it to rotate. Turbine 23 drives shaft 22 to rotate within fixed frame 21, which in turn drives fixed shaft 24. Fixed shaft 24 then moves scraper 25, whose bristles scrub the filter cartridge 5, dispersing stubborn oil or solids adhering to it and preventing blockage of filter holes 6, thus ensuring filtration efficiency. When installing filter cartridge 5, align positioning hole 4 with positioning rod 2, and place fixing sleeve 3 onto positioning rod 2 for positioning. Turning knob 17 will move the fixing rod 15, which in turn moves the locking block 16. The locking block 16 will press against the inclined surface of the baffle 9, causing the baffle 9 to rise a certain distance. The rise of the baffle 9 will cause the circular plate 10 to rise, which in turn will cause the pull rod 11 to rise. The circular plate 10 will also compress the spring 12, causing the spring 12 to contract. When the locking block 16 moves past the baffle 9, the spring 12 will extend, allowing the baffle 9 to fall and block one side of the locking block 16, thus limiting the position of the locking block 16 and the fixed sleeve 3. The filter cartridge 5 can then be installed. To disassemble, pull the pull rod 11 to raise it, causing the baffle 9 to rise and no longer block one side of the locking block 16. Then, turn knob 17 in the opposite direction to move the locking block 16 out of the groove on the positioning rod 2. This will allow the filter cartridge 5 to be pulled up and removed for deep cleaning.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
