Description

Technical Field

[0001] This utility model relates to the field of vacuum pump technology, and in particular to an oil and gas recovery dry screw vacuum pump. Background Technology

[0002] A vacuum pump is a device that creates or maintains a low-pressure environment by removing gas from a confined space. Based on different working principles and application fields, vacuum pumps are mainly classified into the following types: rotary vane vacuum pumps, dry vacuum pumps, molecular pumps, diffusion pumps, screw vacuum pumps, and liquid ring pumps. Dry screw vacuum pumps are a modern type of vacuum pump. Their basic working principle utilizes the interaction of two or more screws; the rotation of the screws pushes the gas from the inlet side to the exhaust port, compressing it.

[0003] Oil and gas recovery refers to the process in the petroleum, natural gas, and chemical industries of recovering oil and gas resources (such as light hydrocarbons and dissolved oil and gas in natural gas) to reduce energy waste, lower environmental pollution, and improve resource utilization. In the oil and gas recovery process, vacuum pumps can be used to extract gases or pump oil and gas mixtures. However, traditional vacuum pump designs do not adequately suppress vibration, making them more prone to problems, especially under high loads or long-term operation. The pump body cannot maintain stability, thus affecting performance. Traditional dry screw vacuum pumps may also occupy a large space during transportation and storage due to the lack of flexible adjustable structures in their design, increasing transportation costs and storage space requirements. Therefore, this invention proposes an oil and gas recovery dry screw vacuum pump to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dry screw vacuum pump for oil and gas recovery.

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

[0006] A dry screw vacuum pump for oil and gas recovery includes a pump body. A support is fixedly installed on the lower side of the pump body. Gears are rotatably connected to the lower side of the support on both the left and right sides. A fixing block is fixed to the lower side of one gear, and a fixing block is fixed to the lower side of the other gear. A sliding movable block is provided on the lower side of the fixing block. A stabilizing seat is rotatably connected to the outer side of both the fixing block and the movable block. A slot is provided on the upper side of the stabilizing seat. Inserts corresponding to the slot are slidably provided on the left and right sides of the support surface. A rotating seat is rotatably connected to the front side of the support surface, and a pull plate is rotatably connected to the upper end of the rotating seat.

[0007] Preferably, pulleys are installed on both the left and right sides of the lower rear side of the support, and the lower side of the stabilizer is located below the pulleys.

[0008] Preferably, the two gears mesh with each other, the fixed block has two slots on the lower side, and the movable block has two protrusions on the upper side corresponding to the slots.

[0009] Preferably, a limiting block located on the lower side of the support is fixed at the lower end of the rotating seat, and a second insert is provided at one end of the upper and lower sides of the limiting block.

[0010] Preferably, the limiting block is located between the fixed block and the movable block, and the lower side of the fixed block and the upper side of the movable block are provided with limiting grooves corresponding to the second insertion block.

[0011] Preferably, a torsion spring is provided at the junction of the pull plate and the rotating seat, and a handle is provided at the outer end of the pull plate.

[0012] Preferably, a slider is provided on one side of the pull plate, the slider slides horizontally on the surface of the support, and a sliding shaft is fixed on both the left and right sides of the rear side of the support, and a spring is sleeved around the sliding shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This practical pump body ensures stability during operation through the cooperation of the support seat and the stabilizing seat, reducing vibration and friction. The design of the left and right stabilizing seats can effectively support the pump body and ensure its smooth operation. In addition, the pump body's rotating seat and pull plate system make the equipment adjustment more convenient. Users can complete the angle adjustment and position change with simple operation, improving the flexibility and ease of use of the equipment.

[0015] 2. This practical pump has a foldable stabilizer, which makes it easier to reduce space occupation during transportation and storage. By disassembling and adjusting the stabilizer and various components, the equipment can be compressed into a smaller volume to adapt to different transportation and storage needs. This design greatly reduces transportation costs and space limitations, making it more convenient for applications that require frequent movement.

[0016] 3. The gear transmission system of this practical pump improves working efficiency while reducing equipment vibration and friction, ensuring long-term stable operation. The use of dry screw technology avoids the oil and gas pollution problems that may be caused by traditional oil-sealed pumps, reducing environmental pollution. The limit block and insert block design of the equipment enhances operational safety, preventing accidental movement or detachment of components during transportation and use, ensuring the safety and stability of the system.

[0017] In summary, the design of the dry screw vacuum pump for oil and gas recovery has been optimized in many aspects, and it has the advantages of stable structure, simple operation, convenient transportation, high safety and strong adaptability. It can not only provide an efficient and clean oil and gas recovery solution, but also reduce environmental pollution while improving work efficiency. In addition, its adjustable and easy-to-disassemble design makes the equipment more convenient in maintenance and transportation. Attached Figure Description

[0023] 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.

[0024] Reference Figure 1-4A dry screw vacuum pump for oil and gas recovery includes a pump body 1. A support seat 2 is fixedly installed on the lower side of the pump body 1. Gears 17 are rotatably connected to the lower side of the support seat 2 on both the left and right sides. A fixing block 10 is fixed to the lower side of one gear 17, and a fixing block 11 is fixed to the lower side of the other gear 17. A sliding movable block 12 is provided on the lower side of the fixing block 10 and the movable block 12. A stabilizing seat 3 is rotatably connected to the outer side of the fixing block 10 and the movable block 12. A slot 9 is opened on the upper side of the stabilizing seat 3. Inserts 16 corresponding to slot 9 are slidably provided on the left and right sides of the surface of the support seat 2. Pulleys are installed on the lower left and right sides of the rear side of the support seat 2. The lower side of the stabilizing seat 3 is located under the pulleys. At this time, the left and right stabilizing seats 3 serve as supports for the support seat 2 and the pump body 1 on it, ensuring that the pump body 1 can work stably on the surface of the support seat 2.

[0025] Furthermore, the two gears 17 mesh with each other, and the lower side of the fixed block 10 has two slots 13 on the left and right, and the upper side of the movable block 12 has two protrusions on the left and right corresponding to the slots 13. The front side of the support 2 is rotatably connected to the rotating seat 4, and the lower end of the rotating seat 4 is fixed with a limiting block 14 located on the lower side of the support 2. The upper and lower ends of the limiting block 14 are provided with inserts 19. The limiting block 14 is located between the fixed block 10 and the movable block 12. The lower side of the fixed block 10 and the upper side of the movable block 12 are provided with limiting grooves 15 corresponding to the inserts 19. When it is necessary to retract the two side stabilizing seats 3, When transporting the pump body 1, pry open the left and right insert blocks 16 on the surface of the support seat 2 so that the insert blocks 16 disengage from the slots 9. Then, the fixed block 10 and the stabilizing seat 3 at the outer end of the movable block 12 can be rotated. Rotate the stabilizing seat 3 upward by 180 degrees and pull the movable block 12 outward so that the protrusion on the upper side of the movable block 12 disengages from the corresponding slot 2 13 on the lower side of the fixed block 10. Then, the fixed block 10 and the fixed block 2 11 can be rotated forward. Due to the action of the meshing gear 17, the two fixed blocks are parallel to each other until the two stabilizing seats 3 are placed in front of the support seat 2.

[0026] Furthermore, a pull plate 8 is rotatably connected to the upper end of the rotary seat 4. A torsion spring is provided at the junction of the pull plate 8 and the rotary seat 4, and a handle 18 is provided at the outer end of the pull plate 8. A slider 5 is provided on one side of the pull plate 8. The slider 5 slides horizontally on the surface of the support seat 2. Sliding shafts 6 are fixed on both the left and right sides of the rear side of the support seat 2, and springs 7 are sleeved around the circumference of the sliding shafts 6. By prying open one side of the slider 5, the slider 5 loses its contact with the surface of the pull plate 8 on one side, and the rotary seat 4 structure can be rotated 90 degrees. The inserts 19 on the upper and lower sides of the lower limit block 14 of the rotary seat 4 slide into the corresponding limiting grooves 15 on the surfaces of the fixed block 10 and the movable block 12. This causes the limit block 14 after rotation to bind one side of the fixed block 10 and the other side of the movable block 12. Without the contact of the outer slider 5, the pull plate 8 is automatically rotated open by the torsion spring. Then, the pump body 1 structure on the support seat 2 can be pulled through the pull plate 8 connected by the handle 18.

[0027] 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.
