Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic stations, in particular to a hydraulic station with a dust removal structure. Background Art

[0002] The hydraulic station is a hydraulic source device or a hydraulic device including a control valve, which is composed of a hydraulic pump, a driving motor, an oil tank, a directional valve, a throttle valve, a relief valve, etc. It supplies oil according to the requirements of the driving device, controls the direction, pressure and flow of the oil flow, and converts mechanical energy into the pressure energy of the hydraulic oil. At present, most hydraulic stations use metal shells and are directly exposed to the air. Since a large amount of dust is generated during processing in the workshop, after a long time of use, the dust will accumulate on the hydraulic station, causing its surface to become dirty, which in turn affects the operation and shortens the service life. Therefore, it is necessary to design a dust removal mechanism to clean the surface of the hydraulic station.

[0003] The existing publication number CN215861105U provides a hydraulic station with a dust-proof function, which includes a hydraulic station body. By arranging a fan and a dust removal box on the hydraulic station body, dust can be sucked into the dust removal box and filtered with a filter bag to realize the dust-proof function of the hydraulic station. At the same time, the setting of the swing component can expand the dust suction range to avoid dust accumulation on the surface of the hydraulic station and affect its use: However, when using this device, it is necessary to turn several mounting screws in turn and place or remove the two sides of the bottom end of the filter bag into or out of the limit holes to realize the disassembly and assembly of the filter bag. The operation is relatively cumbersome. In order to simplify the operating steps, we provide a hydraulic station with a dust removal structure. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] In one embodiment, Figure 1-Figure 4 As shown, a hydraulic station with a dust removal structure includes an oil tank 1, a motor 2 and a dust removal box 3 are fixedly installed on both sides of the top of the oil tank 1, an n-shaped air outlet channel 4 for guiding clean air is fixedly connected to the top of the dust removal box 3, a swing dust collection unit 5 is fixedly installed on the top of the oil tank 1 between the motor 2 and the dust removal box 3, the fan part of the swing dust collection unit 5 is fixedly connected to the side wall of the dust removal box 3, and the swing dust collection unit 5 can collect dust air in a large range through the fan and merge it into the inside of the dust removal box 3;

[0025] The top inner wall of the dust removal box 3 is fixedly connected with a frame 6, and the outer side of the frame 6 is sleeved with a filter bag 7. The frame 6 is composed of a plurality of vertically distributed circular rings and a plurality of connecting vertical rods on the outer sides of the circular rings, and the outer diameter of the circular rings matches the inner diameter of the filter bag 7, so that the filter bag 7 can be fully unfolded. The top of the filter bag 7 is fixedly connected with a fixing ring 8, and the fixing ring 8 is fixedly connected to the top inner wall of the dust removal box 3 through a mounting assembly, thereby realizing the fixed installation of the filter bag 7;

[0026] The mounting assembly includes two circular mounting holes 9, which are symmetrically arranged on both sides of the fixing ring 8. Two clamping blocks 10 are clamped on the inner side of each mounting hole 9. The clamping block 10 is composed of a clamping portion at the top and a limiting portion at the bottom. The limiting portion is a semi-conical structure with thinner ends and thicker middle portion. The outer diameter of the thickest part in the middle of the limiting portion matches the diameter of the mounting hole 9. This structure can stably support the outer edge of the mounting hole 9 of the fixing ring 8, and it is also convenient for the two clamping blocks 10 to come close to each other and escape from the mounting hole 9 along the inclined surface of the truncated cone. A spring 11 is fixedly connected between the two clamping blocks 10, and the spring 11 is used to continuously A thrust force in the direction of moving away from each other is provided for the two card blocks 10, thereby improving the stability of the card block 10 and the mounting hole 9. A circular hole is provided on the side wall of the card block 10, and the spring 11 is located inside the circular hole to achieve complete fit between the side walls of the two card blocks 10, so as to facilitate penetration of the mounting hole 9. A T-shaped slider 12 is fixedly connected to the top of each card block 10, and two symmetrically distributed slide grooves 13 are provided on the top inner wall of the dust removal box 3. The two T-shaped sliders 12 on the same side slide inside the corresponding slide grooves 13. The sliding connection between the T-shaped slider 12 and the slide groove 13 is used to achieve stable movement of the two card blocks 10 toward or away from each other along a straight line;

[0027] A guide component is arranged inside the dust removal box 3 on the outside of the filter bag 7, and the guide component is used to distribute the introduced dust air more evenly around the outside of the filter bag 7. The guide component is an annular tubular air guide duct 14, and the air guide duct 14 is connected to the air inlet duct of the fan. A plurality of through holes 15 equidistantly distributed in a circle are provided on the inner side of the air guide duct 14 to achieve the effect of uniform air distribution. The outer diameter of the fixing ring 8 is smaller than the inner diameter of the air guide duct 14. This arrangement is to ensure that the fixing ring 8 can be smoothly moved upward along the frame 6, thereby achieving the effect of the filter bag 7 being sleeved on the outside of the frame 6.

[0028] When the filter bag 7 needs to be removed during the use of this device, the door of the dust box 3 is opened first, and then the two blocks 10 on both sides are squeezed with both hands until the side walls fit together. The spring 11 is compressed under force, and the T-shaped slider 12 at the top slides along the slide groove 13 accordingly with the movement of the block 10. When the two blocks 10 fit together, the mounting hole 9 on the fixing ring 8 can slide down through the truncated cone inclined surface of the limiting portion of the block 10. At this time, the fixing ring 8 can be directly grasped and moved down, and the limiting portion of the block 10 will move upward out of the mounting hole 9 to release the limit on the fixing ring 8. The fixing ring 8 is continued to be moved down to the bottom of the frame 6, and the filter bag 7 will also be separated from the sleeve of the frame 6. Finally, the fixing ring 8 and the filter bag 7 are directly taken out of the dust box 3, and the removal of the filter bag 7 is completed. When installing and replacing a new filter bag 7, the fixing ring 8 is directly pulled out from the bottom of the frame 6 along its The outer side moves upward, and the filter bag 7 is unfolded and sleeved on the outer side of the frame 6. When the fixing ring 8 contacts the block 10, the mounting hole 9 thereon will squeeze the two blocks 10 along the truncated cone slopes to squeeze them close to each other until the side walls fit together, the spring 11 is compressed, and the fixing ring 8 continues to move upward until it contacts the top inner wall of the dust removal box 3, and the mounting hole 9 also simultaneously passes through the limiting part of the block 10 and engages with its clamping part. The spring 11 rebounds and pushes the two blocks 10 outward, so that the limiting part of the block 10 is firmly supported on the outer side of the bottom edge of the mounting hole 9, that is, the fixing ring 8 and the filter bag 7 are fixedly installed; in addition, when the dust gas is merged into the dust removal box 3 through the swinging dust collecting unit 5, it will flow along the air duct 14 and flow out from the through hole 15, and then be more evenly distributed around the outer side of the filter bag 7 to improve the utilization rate of the filtering surface of the filter bag 7.

[0029] The above-mentioned embodiment discloses a hydraulic station with a dust removal structure, wherein, by setting a frame 6 and a mounting assembly, the mounting hole 9 and the clamping block 10 can be automatically engaged by simply moving the fixing ring 8 upward along the outer side of the frame 6, thereby completing the unfolding and fixing of the filter bag 7, thereby simplifying the steps of disassembling and assembling the filter bag 7; in addition, by setting a guide assembly, the introduced dust gas can flow through the surface of the filter bag 7 more evenly, thereby improving the utilization rate of the filter bag 7.

[0030] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
