Description

Technical Field

[0001] This application relates to the field of oil suction devices, and more particularly to a self-priming oil suction device. Background Technology

[0002] An oil separator is a wastewater pretreatment device that uses the density difference between oil and water to separate oil and water. It is mainly used to remove suspended oil and some emulsified oil from wastewater. The oil separator separates oil and water by natural flotation. When the oily wastewater flows slowly in the horizontal direction, the oil droplets with lower density float to the surface of the water.

[0003] Existing oil suction devices extract oil by placing a water pump at the bottom of the grease trap. Because water and oil have different densities, the oil floats on the water surface. Therefore, the water in the grease trap needs to be drained first before the oil is extracted, which reduces work efficiency. Utility Model Content

[0004] To address the aforementioned problems, this application provides a self-priming oil suction device.

[0005] The self-priming oil suction device provided in this application adopts the following technical solution:

[0006] A self-priming oil suction device includes a base, on which an oil suction assembly is provided. The oil suction assembly includes two pump bodies fixedly connected to the upper surface of the base. A corrugated hose is fixedly connected to the water suction end of each pump body, and an oil suction bucket is fixedly connected to the top end of the corrugated hose. A fixing rod is fixedly connected to each pump body on the upper surface of the base. A connecting block is sleeved on each fixing rod. The end of the connecting block away from the fixing rod is fixedly connected to the oil suction bucket. A moving component for driving the connecting block to rise and fall is provided on the fixing rod. A water outlet pipe is fixedly connected to the water outlet end of each pump body.

[0007] By adopting the above technical solution, when in use, the pump body is placed inside the oil separator, with the oil suction bucket positioned below the upper layer of oil. By starting the pump body, the oil is drawn into the corrugated hose through the oil suction bucket, and then discharged through the water outlet pipe after passing through the pump body, thus collecting the oil. This avoids the problem of having to drain the water from the oil separator first before extracting the oil, which would reduce work efficiency.

[0008] Preferably, a check valve is installed at the top of the water outlet pipe, a drain pipe is fixedly connected to the top of one of the water outlet pipes, and a connecting pipe is installed at the top of the other water outlet pipe. The end of the connecting pipe away from the water outlet pipe is fixedly connected to the side wall of the drain pipe.

[0009] By adopting the above technical solution, the operation of the two pumps can be controlled according to the needs of the oil extraction efficiency by switching the check valve.

[0010] Preferably, the movable component includes a threaded tube threaded to one of the fixed rods, the bottom end of the threaded tube being located on the upper surface of the connecting block, a U-shaped block being rotatably connected to the bottom end of the threaded tube, the connecting block being located inside the U-shaped block and its lower surface being in contact with the U-shaped block, and a connecting rod being fixedly connected between the two connecting blocks.

[0011] By adopting the above technical solution, the threaded tube is rotated and moved on the fixed rod, which drives the U-shaped block to rise and fall. The U-shaped block drives the connecting block to move up and down, and the connecting rod drives another connecting block to move at the same time. Then, the height of the oil suction bucket is adjusted according to the water level in the oil separator to facilitate the oil suction bucket to suck up oil.

[0012] Preferably, the lower surface of the U-shaped block has a groove, and the fixing rod is located in the groove.

[0013] By adopting the above technical solution, the groove and fixing rod can prevent the U-shaped block from rotating together when the threaded tube rotates, thus improving the stability of the U-shaped block.

[0014] Preferably, the inner sidewalls of the U-shaped block are fixedly connected to positioning rods on both sides of the groove, and the positioning rods are inserted into the connecting block.

[0015] By adopting the above technical solution, the positioning rod is inserted into the connecting block to prevent the connecting block from rotating on the fixed rod during use, which would cause the oil suction bucket to swing and improve the stability of the oil suction bucket.

[0016] Preferably, the upper surface of the base has multiple mounting holes for fixing.

[0017] By adopting the above technical solution, the base can be easily fixed in the oil separator through the mounting holes, preventing the pump body from shaking or tilting during operation, which would affect the oil suction of the oil suction bucket.

[0018] Preferably, a filter screen is fixedly connected to the top of the inside of the oil suction bucket.

[0019] By adopting the above technical solutions, the filter screen can filter out impurities in the oil separator, preventing them from being sucked in during the oil suction process and affecting the operation of the pump.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application utilizes the coordinated arrangement of the pump body, corrugated hose, and oil suction hopper to collect the oil. In use, the pump body is placed inside the oil separator, with the oil suction hopper positioned below the upper layer of oil. By activating the pump body, the oil is drawn into the corrugated hose through the oil suction hopper and then discharged through the water outlet pipe. This process minimizes the need to drain the water from the oil separator before extracting the oil, which reduces work efficiency.

[0022] 2. By rotating the threaded tube, the threaded tube moves on the fixed rod, which drives the U-shaped block to rise and fall. The U-shaped block drives the connecting block to move up and down, and the connecting rod drives another connecting block to move at the same time. Then, according to the water level in the oil separator, the height of the oil suction bucket is adjusted to facilitate the oil suction bucket to suck up oil. Attached Figure Description

[0027] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0028] This application discloses a self-priming oil suction device.

[0029] Reference Figure 1 , Figure 2 and Figure 3 A self-priming oil suction device includes a base 1, on which an oil suction assembly is provided. The oil suction assembly includes a pump body 2, a corrugated hose 3, an oil suction hopper 4, a fixing rod 5, a connecting block 7, and a water outlet pipe 8.

[0030] Two pump bodies 2 are provided, both fixedly connected to the upper surface of the base 1. The pump body 2 is a self-priming pump. When in use, the pump body 2 and the water inlet pipe must be filled with water to form a vacuum state. Two corrugated hoses 3 are provided, respectively fixedly connected to the water suction end of the pump body 2. Two oil suction buckets 4 are provided, respectively fixedly connected to the top of the corrugated hoses 3. Two fixing rods 5 are provided, both fixedly connected to the upper surface of the base 1 and located on one side of the pump body 2. Two connecting blocks 7 are provided, respectively sleeved on the fixing rods 5. The end of the connecting block 7 away from the fixing rod 5 is fixedly connected to the oil suction bucket 4. The fixing rod 5 is provided with a moving component for driving the connecting block 7 to rise and fall. Two water outlet pipes 8 are provided, respectively fixedly connected to the water outlet end of the pump body 2.

[0031] Reference Figure 1 A check valve 9 is installed at the top of the water outlet pipe 8. A drain pipe 10 is fixedly connected to the top of one of the water outlet pipes 8, and a connecting pipe 11 is installed at the top of the other water outlet pipe 8. The end of the connecting pipe 11 away from the water outlet pipe 8 is fixedly connected to the side wall of the drain pipe 10. By switching the check valve 9 on and off, the operation of the two pump bodies 2 can be controlled as needed to adjust the oil extraction efficiency.

[0032] Reference Figure 1 and Figure 2 The moving component includes a threaded tube 12 threadedly connected to one of the fixed rods 5. The bottom end of the threaded tube 12 is located on the upper surface of the connecting block 7. A U-shaped block 13 is rotatably connected to the bottom end of the threaded tube 12. The connecting block 7 is located inside the U-shaped block 13 and its lower surface is in contact with the U-shaped block 13. A connecting rod 17 is fixedly connected between the two connecting blocks 7. By rotating the threaded tube 12, the threaded tube 12 moves on the fixed rod 5, which drives the U-shaped block 13 to rise and fall, causing the U-shaped block 13 to drive the connecting block 7 to move up and down. This, in conjunction with the connecting rod 17, drives the other connecting block 7 to move simultaneously. Then, according to the water level in the oil separator, the height of the oil suction bucket 4 is adjusted to facilitate the oil suction bucket 4 to suck up oil.

[0033] Reference Figure 1 and Figure 2 The lower surface of the U-shaped block 13 has a groove 14, and the fixing rod 5 is located in the groove 14. By using the groove 14 in conjunction with the fixing rod 5, the U-shaped block 13 can be prevented from rotating together when the threaded tube 12 rotates, thereby improving the stability of the U-shaped block 13.

[0034] Reference Figure 1 and Figure 2 The U-shaped block 13 has positioning rods 15 fixedly connected to the inner sidewalls of the groove 14 on both sides. The positioning rods 15 are inserted into the connecting block 7. By inserting the positioning rods 15 into the connecting block 7, the connecting block 7 is prevented from rotating on the fixed rod 5 during use, which would cause the oil suction bucket 4 to swing and improve the stability of the oil suction bucket 4.

[0035] Reference Figure 3The upper surface of the base 1 is provided with multiple mounting holes 16 for fixing. The mounting holes 16 make it easy to fix the base 1 in the oil separator, preventing the pump body 2 from shaking or tilting during operation, which would affect the oil suction of the oil suction bucket 4.

[0036] Reference Figure 1 The top of the oil suction hopper 4 is fixedly connected to a filter screen 6. The filter screen 6 can filter the impurities in the oil separator, preventing the impurities from being sucked in during the oil suction process and affecting the operation of the pump body 2.

[0037] The implementation principle of the self-priming oil suction device in this embodiment is as follows: In use, the base 1 is fixed in the oil separator through the mounting hole 16, and the pump body 2 is installed in the oil separator. Then, by rotating the threaded pipe 12, the threaded pipe 12 moves on the fixed rod 5, driving the U-shaped block 13 to rise and fall, causing the U-shaped block 13 to drive the connecting block 7 to move up and down. In conjunction with the connecting rod 17, another connecting block 7 moves simultaneously. Then, according to the water level in the oil separator, the height of the oil suction bucket 4 is adjusted so that the oil suction bucket 4 is below the upper layer of oil. Then, by starting the pump body 2, the pump body 2 and the water inlet pipe must be filled with water to form a vacuum state. The oil is sucked into the corrugated hose 3 through the oil suction bucket 4, and then discharged through the water outlet pipe 8 after passing through the pump body 2. The oil is collected, which avoids the problem of having to drain the water in the oil separator first and then extract the oil, which reduces the working efficiency.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
