Description

Technical Field

[0001] This utility model relates to the pretreatment of petroleum solid waste, and in particular to a filter press device for treating petroleum solid waste. Background Technology

[0002] Oilfield wastewater is highly polluting wastewater generated during oil exploration and development. It mainly includes drilling wastewater, oil production wastewater, well washing wastewater, and well repair wastewater. Its composition is complex, and pollutant concentrations are high. Direct discharge or improper treatment can severely pollute soil, groundwater, and surface water bodies, threatening the ecological environment and human health. Therefore, efficiently treating oilfield wastewater and achieving compliant discharge or resource utilization is one of the core tasks for environmental compliance and sustainable development in the petroleum industry.

[0003] Therefore, during the oil extraction process, it is necessary to pre-treat the wastewater generated during oil extraction in the oil extraction area. If conditions permit, the pre-treated products can be further processed. If conditions do not permit, the pre-treated products are transported to other places for further processing. In the pre-treatment of wastewater, filter presses are required. However, since oil extraction sites are mostly in the field, especially in the early stages of extraction, the basic conditions are limited, and it is difficult to have large lifting equipment such as cranes and overhead cranes. This makes the transportation and installation of filter presses inconvenient, time-consuming and labor-intensive. Therefore, there is an urgent need for a filter press that is easy to transport and move.

[0004] In the Chinese patent for a belt filter press for dewatering sand washing sludge (publication number: CN214142059U), although it is disclosed that "all four sets of support frames are equipped with casters at their bottom ends", the problem of moving the filter press can be solved by moving the casters. However, it is still inconvenient to transport. Hoisting equipment is still required to place the filter press on the transport vehicle. Moreover, due to the presence of casters, the filter press needs to be fixed to the transport vehicle, making transportation extremely troublesome. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a filter press device for petroleum solid waste treatment.

[0006] The purpose of this utility model is achieved through the following technical solution: a filter press device for treating petroleum solid waste, comprising a frame, on which a filter press assembly is installed, the front end of the frame extending forward to form an installation platform, on which an oil supply assembly and an electrical control assembly are installed, the electrical control assembly being located on one side of the oil supply assembly, at least two lifting support assemblies being installed on the outer side wall of the frame, the lifting support assembly comprising an upper cylinder mounting cylinder and a lower cylinder mounting cylinder, the upper cylinder mounting cylinder and the lower cylinder mounting cylinder being connected, a lifting cylinder being installed inside the upper cylinder mounting cylinder, a hinge seat being installed at the front end of the lifting rod of the lifting cylinder, a hinge shaft being provided on the outer side wall of the frame and hinged to the hinge seat, a telescopic cylinder being installed at the top of the lower cylinder mounting cylinder, a receiving cavity being provided at the bottom of the lower cylinder mounting cylinder, a universal wheel being installed on the telescopic shaft of the telescopic cylinder, and the universal wheel being located inside the receiving cavity, a downwardly extending front support seat being provided at the bottom of the installation platform, a rear support seat being installed on the fixing plate at the rear end of the filter press assembly, the bottom of the front support seat and the support seat being on the same horizontal plane.

[0007] Optionally, baffles are provided on the left and right sides of the frame, the baffles extend outward, and a second magnetic attraction part is provided on the outer wall of the lower or upper hydraulic cylinder mounting cylinder, and a first magnetic attraction part is provided at the bottom of the baffle to magnetically attract the corresponding second magnetic attraction part.

[0008] Optionally, the hinge seat has a U-shaped structure, with a first stop and a second stop detachably installed on the outer side wall of the frame. The first stop fits against one side wall of the corresponding hinge seat, and the second stop fits against the other side wall of the corresponding hinge seat.

[0009] Optionally, mounting holes are provided on the outer side wall of the frame, and the second stop is inserted into the corresponding mounting hole.

[0010] Optionally, the electrical control components include a housing, in which a power supply and a controller are installed. The controller is connected to the hydraulic pumps of the filter press assembly, the lifting cylinder, and the telescopic cylinder, respectively, and the power supply provides power to the controller and the corresponding hydraulic pumps.

[0011] Optionally, multiple central support seats are also provided on the outer side wall of the frame, with the bottom of the central support seats, front support seats, and support seats on the same horizontal plane.

[0012] The present invention has the following advantages: The filter press device of the present invention can raise the horizontal height of the frame through the lifting support assembly, and can change the filter press device from the initial support of the lower cylinder mounting cylinder to the support of the universal wheels. When the filter press device is supported by the universal wheels, it can be pushed. After the horizontal height of the frame is raised, the filter press device can span the carriage. Then, when the lifting cylinder is reset, the support seat can be placed on the carriage, which makes the filter press device easy to load, unload and transport. Therefore, the loading, unloading, transportation and movement of the entire filter press device do not require hoisting equipment, so it can be moved and installed even in poor foundation conditions.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, a filter press device for treating petroleum solid waste includes a frame 1, on which a filter press assembly 2 is mounted. The front end of the frame 1 extends forward to form an installation platform 4, on which an oil supply assembly and an electrical control assembly 5 are mounted. The electrical control assembly 5 is located on one side of the oil supply assembly. At least two lifting support assemblies 6 are mounted on the outer side wall of the frame 1. In this embodiment, lifting support assemblies 6 are mounted at both the front and rear ends of the outer side wall of the frame 1. The frame 1 is a rectangular frame 1, meaning that there are four lifting support assemblies 6 on the frame 1, and the four lifting support assemblies 6 are arranged in a matrix, as shown below. Figure 4 As shown, the lifting support assembly 6 includes an upper cylinder mounting cylinder 23 and a lower cylinder mounting cylinder 24, which are connected. In this embodiment, the upper cylinder mounting cylinder 23 and the lower cylinder mounting cylinder 24 are detachably connected by a bolt assembly. A lifting cylinder 21 is installed inside the upper cylinder mounting cylinder 23. Therefore, a stepped through hole is provided at the bottom of the upper cylinder mounting cylinder 23, and the cylinder body of the lifting cylinder 21 is installed in the stepped through hole. The lifting rod of the lifting cylinder 21 passes through the stepped through hole, and a hinge seat 27 is installed at the front end of the lifting rod of the lifting cylinder 21. A hinge shaft 13 is provided on the outer side wall of the frame 1 and is hinged to the hinge seat 27. The hinge seat 27 is hinged to the hinge shaft 13. When the lifting rod rises and falls, it can drive the frame 1 to rise and fall. Furthermore, in the hinge seat 23... The inner sleeve of the 7 is rotatably mounted on the hinge shaft 13. When the sleeve wears out, it can be replaced. Alternatively, in another embodiment, a bearing can be fitted onto the hinge shaft 13 and then fitted into the hinge seat 27. In this way, the entire lifting support assembly 6 can easily rotate relative to the hinge shaft 13. When the lifting cylinder 21 is raised or lowered, the four lower cylinder mounting cylinders 24 are mounted on the same horizontal plane, and the lifting support assembly 6 is in a vertical state. Therefore, when the lifting cylinder 21 is raised or lowered, the horizontal height of the entire frame 1 will rise or fall accordingly. In this embodiment, when the horizontal height of the frame 1 is raised, the height of the filter press assembly 2 from the ground also increases. At this time, the trailer can enter under the filter press assembly 2. When the lifting cylinder 21 is reset, as Figure 5 As shown, the entire filter press assembly 2 is placed on the carriage. In this embodiment, as... Figure 4 As shown, a telescopic cylinder 22 is installed on the top of the lower cylinder mounting cylinder 24, and a receiving cavity 25 is provided at the bottom of the lower cylinder mounting cylinder 24. A universal wheel 26 is installed on the telescopic shaft of the telescopic cylinder 22, and the universal wheel 26 is located inside the receiving cavity 25. Therefore, when the filter press is installed on the truck bed, no lifting equipment is needed; instead, the telescopic cylinder 22 operates. Figure 3As shown, the casters 26 are pushed out of the receiving cavity 25, at which point the frame 1 rises to a certain height. The weight of the filter press is then supported by the four casters 26. Based on the position of the carriage, the filter press is moved to a suitable position, and then the lifting cylinder 21 operates again, raising the horizontal height of the frame 1. Once the frame 1 is raised to the appropriate position, the filter press is moved so that it is positioned above the carriage, while the four lifting support components 6 are located on both sides of the carriage. Then, the lifting cylinder 21 resets first, and finally the telescopic cylinder 22 resets. At this point, the filter press is placed on the carriage. Furthermore, the bottom of the mounting platform 4 is also equipped with a downward-extending front support. The rear support 15 is installed on the fixing plate 3 at the rear end of the filter press assembly 2. The bottom of the front support 11 and the support 15 are on the same horizontal plane. The filter press assembly 2 is supported by the front support 11 and the rear support 15, which can prevent the filter press assembly 2 from contacting the carriage, thereby preventing damage to the filter press assembly 2 and ensuring the reliability of the filter press assembly 2 during transportation. Furthermore, multiple middle support 12 are also provided on the outer wall of the frame 1. The middle support 12, the front support 11 and the bottom of the support 15 are on the same horizontal plane. The middle support 12 further increases the structural strength of the frame 1, so that the filter press device can be better supported on the carriage and prevent deformation of the middle part of the frame 1.

[0021] In this embodiment, as Figure 1 As shown, baffles 14 are provided on the left and right sides of the frame 1. The baffles 14 extend outward. A second magnetic part 8 is provided on the outer wall of the lower cylinder mounting cylinder 24 or the upper cylinder mounting cylinder 23. A first magnetic part 7 is provided at the bottom of the baffle 14 to magnetically attract the corresponding second magnetic part 8. During transportation, in order to avoid damage to the lifting support assembly 6, the lifting support assembly 6 is rotated so that the lifting support assembly 6 is attracted to the bottom of the baffle 14 through the first magnetic part 7 and the second magnetic part 8. In this embodiment, the first magnetic part 7 and the second magnetic part 8 can be magnets.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the hinge seat 27 has a U-shaped structure. A first stop 9 and a second stop 10 are detachably installed on the outer wall of the frame 1. The first stop 9 is fitted with one side wall of the corresponding hinge seat 27, and the second stop 10 is fitted with the other side wall of the corresponding hinge seat 27. Furthermore, an installation hole is opened on the outer wall of the frame 1, and the second stop 10 is inserted into the corresponding installation hole. Therefore, in use, one side wall of the hinge seat 27 is first fitted with the first baffle 14, and then the second stop 10 is inserted into the installation hole. At this time, the second stop 10 is fitted with the other side wall of the hinge seat 27. The first baffle 14 and the second baffle 14 can restrict the hinge seat 27 and prevent the hinge seat 27 from rotating. Therefore, when the lifting cylinder 21 is working, it can ensure that the entire lifting support assembly 6 is in a vertical lifting state, thereby ensuring the reliability of the lifting of the frame 1.

[0023] In this embodiment, the electrical control component 5 includes a housing, inside which a power supply and a controller are installed. The controller is connected to the hydraulic pumps of the filter press component 2, the lifting hydraulic pump 21, and the telescopic hydraulic pump 22, respectively. The power supply provides power to the controller and the corresponding hydraulic pumps. Therefore, in the case of power supply in the field, the hydraulic pumps of the lifting hydraulic pump 21 and the telescopic hydraulic pump 22 are powered by the power supply, and then controlled by the controller, the lifting and resetting of the lifting hydraulic pump 21 and the telescopic hydraulic pump 22 can be realized. In this embodiment, the corresponding hydraulic pumps are controlled by the controller, which is the prior art and will not be described in detail.

[0024] The working process of this utility model is as follows: The filter press is placed on an empty, flat surface. At this time, if... Figure 2 As shown, both the lifting cylinder 21 and the telescopic cylinder 22 are in their initial positions, and both the first baffle 14 and the second baffle 14 are installed. At this time, the filter press is supported by the lifting support assembly 6, while the lower cylinder mounting cylinder 24 is in contact with the ground. When the filter press needs to be transported, such as... Figure 3 As shown, the telescopic cylinder 22 operates, causing the casters 26 to extend out of the receiving cavity 25. At this time, the lower cylinder mounting cylinder 24 is lifted off the ground, and the weight of the filter press is supported by the four casters 26. Applying a pushing or pulling force to the filter press will move it. Depending on the position of the truck bed, the filter press is moved to the designated position, aligning it with the truck bed. Then, the lifting cylinder 21 operates, raising the lifting rod and thus lifting the frame 1. Once the bottom of the current support base 11 is higher than the truck bed, the lifting cylinder 21 stops operating and maintains the stable position of the lifting rod. Then, the filter press assembly 2 is pushed, moving it towards the front of the trailer. When it reaches the designated position, as shown... Figure 5As shown, the lifting cylinder 21 resets. At this time, the front support seat 11, the middle support seat 12, and the rear support seat 15 are placed on the carriage and support the filter press device. Then, the telescopic cylinder 22 resets again, and the universal wheel 26 enters the receiving cavity 25. At this time, the lifting support assembly 6 is lifted off the ground and no longer supports the filter press assembly 2. Then, the second stop block 10 is removed. Figure 6 As shown, by prying the lifting support assembly 6, the first magnetic suction part 7 and the second magnetic suction part 8 are magnetically attracted, thereby storing the lifting support assembly 6 under the baffle 14, thus avoiding damage to the lifting support assembly 6 during transportation. After the filter press device is transported to the designated position, the lifting support assembly 6 is pryed to disengage the first magnetic suction part 7 and the second magnetic suction part 8, and the lifting support assembly 6 is then in a vertical position. The second baffle 14 is then installed, and the telescopic cylinder 22 is activated, the caster wheel 26 contacts the ground, and then the lifting cylinder 21 is activated, increasing the horizontal height of the frame 1. Finally, the filter press device is moved, thus detaching it from the carriage. Finally, the lifting cylinder 21 is reset, and after the filter press device is moved to the designated position, the telescopic cylinder 22 is reset, so that the lower cylinder support cylinder contacts the ground. At this point, the filter press device cannot be moved, thus realizing the installation of the filter press device. During the entire transportation and movement process, no hoisting equipment is required, and the movement is convenient and the transportation is reliable.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
