Description

TECHNICAL FIELD

[0001] The utility model belongs to pipeline dismantling technical field, concretely relates to a pipeline filter dismounting tool. BACKGROUND

[0002] The power workshop is mainly responsible for the energy supply of the whole factory, such as cold water, compressed air, steam, negative pressure, etc. The air compressor for generating compressed air is the main equipment. At present, there are 5 sets of air compressors, with a total gas production of 180 Nm³ / min. Among them, 3 sets are American "SULLAIR" brand water-cooled units (gas production: 2 sets are 40 Nm³ / min, and 1 set is 20 Nm³ / min), and 2 sets are "Atlas" ZR oil-free screw compressor units (gas production: 40 Nm³ / min). The main working principle is that the motor drives the male rotor through the elastic coupling, and then the male rotor drives the female rotor to rotate at high speed. With the continuous reduction of the volume between the teeth, the air sucked from the air filter is continuously compressed and the pressure is increased.

[0003] Because the air contains moisture and some oil brought out by the equipment, after compression, at the same temperature, although the temperature rises during the compression process, the compressed air is finally cooled down by the cooler at the back of the equipment. The higher the pressure, the smaller the saturated vapor pressure of water, and the easier the water is to separate out. Therefore, water will separate out from the air compressor, and the water will separate out with the oil. Moreover, over time, there will be more and more water in the gas storage tank. If not removed in time, the moisture will corrode the tank wall and reduce the volume, and our production process requires that the compressed air user end cannot contain water and oil.

[0004] Therefore, we installed a pipeline filter (there are front-stage filter, middle-stage filter in front of the dryer, and rear-stage filter at the rear end) on the compressed air pipeline. When the pressure difference of the filter is greater than 0.45 bar or the running time is 4000 hours, the filter element needs to be replaced. The filter element is in the shape of a cylinder, and the side of the cylinder is made of soft filter cotton or filter hole-shaped soft material. When replacing, only the soft material on the side of the cylinder can be rotated clockwise, which is easy to deform the filter element by force, and the screw thread is many, which needs to be rotated many times to install, and finally, a larger force is needed to install and tighten the part close to the fastening, so the installation is difficult and has become a problem.

[0005] How to solve the problem of difficult installation and disassembly, both convenient installation and disassembly, and not damage the filter element, a pipeline filter element installation and disassembly tool for air compressor is needed to design. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0028] In order to more clearly illustrate the technical solutions of the embodiments of the present application and the prior art, specific implementation manners of the present application will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without any creative labor, and other embodiments can also be obtained. In addition, the design direction is only to represent the relative position relationship between the components, not the absolute position relationship.

[0029] The embodiment of the present application provides a pipeline filter dismounting tool, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , mainly including connecting rod 1, chuck 2, butt joint part 3, the front end of connecting rod 1 is fixedly connected with the back side of chuck 2, the front side of chuck 2 is provided with a plurality of clamping columns 22 corresponding to the relative position of a plurality of dismounting holes of the filter core bottom of pipeline filter;The rear end of connecting rod 1 is provided with butt joint part 3 for establishing transmission relationship with external tool;The plurality of clamping columns 22 carried on chuck 2 are sequentially inserted into a plurality of dismounting holes, and external tool rotates connecting rod 1 to drive chuck 2 to dismount pipeline filter.

[0030] The dismounting tool of the present application is used for dismounting the filter core 4 of the pipeline filter, opening the bottom of the pipeline filter, as shown in Figure 1 , the figure is the inverted direction of the pipeline filter, a plurality of filter cores 4 are placed in the filter chamber 6, and the outside is the pipeline wall 7;The filter core 4 is above the edge of the bottom of the pipeline filter, and the dismounting hole of the filter core 4 is located in the pipe wall port of the pipeline filter, so that the dismounting tool is directly connected with the butt joint, and the dismounting tool will be hindered by the pipeline wall 7, not only the swing space is limited, but also the torque is limited, and the filter core 4 cannot be dismounted well.

[0031] The dismounting tool provided by the present application can make the length of connecting rod 1 greater than the depth of the filter core in the pipeline filter, and the dismounting space is moved downward by connecting rod 1, so that the dismounting tool 5 can be located in the space outside the pipeline filter to swing and dismount, not only the swing space is not limited, but also the torque is not limited, and the dismounting tool can be freely implemented, which is convenient for dismounting and installing the filter core.

[0032] It should be clear that the bottom of the filter core is a disc-shaped structure, that is, a dismounting disc 41, and the upper surface of the disc has four symmetrical circular holes, that is, dismounting holes;The distance of the four circular holes from the center is the same, and they are evenly distributed in a ring shape. Therefore, when designing the dismounting tool, the corresponding clamping columns 22 can be set according to the size and relative position relationship of the dismounting holes, and the plurality of clamping columns 22 are simultaneously inserted into the dismounting holes, so that the dismounting tool and the bottom of the filter core rotate synchronously, and the dismounting tool is rotated by the external dismounting tool, thereby driving the filter core to rotate, completing the dismounting and installation.

[0033] In a specific embodiment, the distance from the bottom of the filter core to the bottom of the pipeline filter is 100 mm, so that a 122 mm long connecting rod 1 can be selected, so that the dismounting tool can be extended to the outside of the pipeline through the connecting rod 1 while clamping the filter core to implement installation or dismounting.

[0034] In the embodiment, the diameter of the disc (i.e., the dismounting disc 41) of the filter core is 55 mm, the diameter of each of the four round holes is 8 mm, the depth of each of the four round holes is 12 mm, and the four round holes are all located on the circumference of a circle with a diameter of 45 mm, so that a base plate 21 with a diameter of 55 mm is required, and four clamping columns 22 with a diameter of 7 mm and a height of 10 mm are symmetrically arranged on the circumference of a circle with a diameter of 45 mm and centered on the center of the base plate 21, so as to form the chuck 2 composed of the base plate 21 and the plurality of clamping columns 22.

[0035] The plurality of clamping columns 22 are arranged on the front side (front face) of the base plate 21, and the front end of the connecting rod 1 is vertically fixed to the center of the back side (front face) of the base plate 21, and the plurality of clamping columns 22 are distributed in a ring shape around the center of the base plate 21.

[0036] In the embodiment of the present application, please refer to Figure 3 , the chuck 2 can be disc-shaped, and the corresponding base plate 21 can also be disc-shaped, and the plurality of clamping columns 22 can be arranged according to the size and position shown in the specific example.

[0037] In another feasible embodiment, the chuck 2 can also be of other structural forms, such as a cross structure, and the base plate 21 is cross-shaped, as shown in Figure 4 , the front end of the connecting rod 1 is vertically fixed to the center of the back side of the base plate 21, and each of the cross end points of the front side of the base plate 21 is provided with a clamping column 22.

[0038] In order to strengthen the structural stability, the front end of the connecting rod 1 is fixed to each of the supports of the cross-shaped support of the base plate 21.

[0039] In order to adapt to filter cores with different depths, connecting rods 1 with different lengths can be selected, and the connecting rod 1 and the chuck 2 can be designed to be detachably fixed, so that only connecting rods 1 with different lengths are required to adapt to the installation and dismounting requirements of filter cores with different depths. At the same time, for filter cores with different sizes, chucks 2 with different diameters can also be configured, so that the connecting rod 1 and the chuck 2 of the dismounting tool can be freely matched, the application range is large, and the universality is good.

[0040] The structure of the connecting rod 1 can be functionally divided into a rod body, a fixed part at the front end, and a butt joint part 3 at the rear end. When the butt joint part 3 is an internally recessed ratchet sleeve, the cross-sectional size (such as diameter) of the rod body can be smaller than that of the butt joint part 3, so that the butt joint part 3 can bear greater torque transmission. The same applies to the fixed part at the front end.

[0041] In a feasible embodiment, the back side of the chuck 2 is provided with a connecting column which is fixed vertically at the center of the back side of the chuck 2; the front end of the connecting rod 1 is provided with a concave connecting hole, and the connecting column is axially fixed in the connecting hole, so that the chuck 2 rotates synchronously with the connecting rod 1.

[0042] When the fixing part is a concave connecting hole, the cross-sectional size (such as diameter) at the position of the fixing part can be increased, which can be the same as the size of the butt joint part 3.

[0043] It can be understood that the fixing form between the connecting column and the connecting hole can be screwing or bolted and pinned, which can keep synchronous rotation.

[0044] In the embodiment of the application, the rear end of the connecting rod 1 is axially provided with a butt joint part 3, and a driving relationship is established between the butt joint part 3 and the external dismounting tool 5, so that the dismounting tool 5 can drive the connecting rod 1 to synchronously drive the chuck 2 to rotate.

[0045] In a feasible embodiment, the rear end of the connecting rod 1 is axially provided with a concave driving hole, and the cross section of the driving hole is polygonal. Specifically, the butt joint part 3 can be a ratchet sleeve, and the external tool can be a ratchet connecting rod.

[0046] In another feasible embodiment, the rear end of the connecting rod 1 is provided as a polygonal prism structure. Specifically, the butt joint part 3 can be a ratchet column, and the external tool is a ratchet sleeve and a connecting rod.

[0047] Of course, the butt joint part 3 can also be of other structural forms, which can be used in cooperation with the corresponding dismounting tool 5 to drive the connecting rod 1 to rotate.

[0048] Of course, the tooling part composed of the butt joint part 3 and the connecting rod 1 can directly implement the dismounting function. The butt joint part 3 can be a horizontal bar structure, which is perpendicular to the connecting rod 1, and the horizontal bar can directly drive the connecting rod 1 to rotate, without the need of the dismounting tool 5. It should be noted that the horizontal bar and the connecting rod 1 can be directly disassembled and assembled, or can be directly fixed.

[0049] When the dismounting tool is applied, the four clamping columns 22 on the chuck 2 are aligned with the four dismounting holes on the filter disc, and are inserted. The chuck 2 tightly abuts against the filter base, the rear end of the connecting rod 1 is located outside the pipeline, and the dismounting tool can drive the connecting rod 1 through the butt joint part 3 to synchronously drive the filter. The rotation direction can be determined according to the actual situation, for example, clockwise rotation is for installing the filter, and counterclockwise rotation is for dismounting the filter.

[0050] It can be understood that the number of clamping columns 22 carried on the chuck 2 can be two, three or four, which can effectively dismount the filter.

[0051] When the filter core is disassembled by the disassembling tool of the present application, the auxiliary taking-out operation of the filter core can be simultaneously implemented by means of the tool. The chuck 2 can be provided with a locking assembly 23. When the clamping column 22 is inserted into the disassembling hole, the locking assembly 23 is hung on the lower end face of the disassembling disc 41, without affecting the rotating process during disassembling. When the disassembling is completed, the filter core 4 needs to be taken out. The disassembling disc 41 can be directly lifted outward by means of the disassembling tool, and the entire filter core is taken out simultaneously.

[0052] It should be noted that the locking assembly 23 is used in cooperation with the disassembling disc 41. Therefore, the size of the disassembling disc 41 should be larger than the main body of the filter core 4, so that the edge of the disassembling disc 41 has the buckle condition.

[0053] In a specific embodiment, the bottom of the filter core 4 is provided with the disassembling disc 41, the disassembling hole is arranged on the disassembling disc 41, the diameter of the disassembling disc 41 is larger than the diameter of the filter core 4, one end of the locking assembly 23 is rotatably arranged on the chuck 2, and the other end of the locking assembly 23 is provided with a lock hook 234. The lock hook 234 is buckled to the edge position of the lower end face of the disassembling disc 41.

[0054] Please refer to Figure 5 During disassembling, the locking assembly 23 can be rotated downward, so that the lock hook 234 is buckled to the lower end face of the disassembling disc 41. Preferably, the lock hook 234 does not contact the lower end face of the disassembling disc 41, without affecting the rotating disassembling operation of the chuck 2. When the auxiliary taking-out operation is performed, the disassembling disc 41 can be pulled by the lock hook 234, and the filter core 4 can be taken out by directly lifting upward.

[0055] For example, the locking assembly 23 can be arranged on the base plate 21 of the chuck 2. The locking assembly 23 can include a positioning rod 231, a swing arm 232, a lock rod 233, and a lock hook 234 arranged at the lower end of the lock rod 233. One end of the positioning rod 231 is fixed to the chuck 2, such as the back side of the base plate 21. The other end of the positioning rod 231 is rotatably connected to one end of the swing arm 232. The rotatable connection between the swing arm 232 and the positioning rod 231 can be without limitation of the rotation angle, or can be limited to the rotation angle, so that the swing arm 232 can be unlocked / locked within the rotation range.

[0056] The other end of the swing arm 232 is provided with the lock rod 233. The connection angle between the lock rod 233 and the swing arm 232 is not limited. The rod body structure of the lock rod 233 can be vertical, as shown in Figure 6 , or can be arc-shaped. However, the height of the lock rod 233 in the vertical direction should be greater than the thickness of the disassembling disc 41 and less than the sum of the thickness of the disassembling disc 41 and the length of the clamping column 22, so that the lock rod 233 has sufficient length to complete the locking, and also has relatively short length to limit the clamping column 22 from completely falling out of the disassembling hole, thereby affecting the locking effect.

[0057] It can be understood that when the locking rod 233 is in an arc shape, the size of the base plate 21 and the dismounting disc 41 can be inconsistent; if the locking rod 233 is in a vertical form, the size difference between the base plate 21 and the dismounting disc 41 needs to be compensated by the swing arm 232, so as to stabilize the locking state of the locking hook 234.

[0058] Taking the vertical state of the locking rod 233 as an example, when the clamping column 22 is inserted into the dismounting hole, the locking hook 234 is buckled to the edge of the lower end surface of the dismounting disc 41, the length of the locking rod 233 can be appropriately lengthened, so that the locking hook 234 is not in direct contact with the dismounting disc 41, but the locking rod 233 does not rotate at will and needs to be assisted by external force to rotate. This requires that the structure realizing the rotational connection between the swing arm 232 and the positioning rod 231 has a state limitation, so that the relative angle between the swing arm 232 and the positioning rod 231 is kept stable in a certain specific state, such as a locked state and a free state. In the locked state, the position of the locking rod 233 is relatively fixed and does not rotate again; in the free state, the swing arm 232 can rotate freely within a certain range based on the rotational connection.

[0059] As another feasible embodiment, a limiting structure such as a tension spring, a torsion spring, a mechanical pressure rod, etc. can be additionally arranged at the structure where the rotational connection is located to limit the rotation angle and lock the rotation angle of the swing arm 232.

[0060] In this application, the locking hook 234 is in a triangular structure, as shown in Figure 6 The side of the right angle short side is fixed to the inner side of the locking rod 233, and the side of the right angle long side is buckled. In order to ensure the convenience of the locking hook 234 in use, a roller set 235 can be arranged on the side of the hypotenuse, the roller set 235 includes a plurality of rollers which are uniformly distributed on the side of the hypotenuse, so that the hypotenuse can automatically slide outward when abutting against the dismounting disc 41, and the locking is completed.

[0061] It can be understood that a plurality of locking buckle assemblies 23 are arranged on the chuck 2, and at least two locking buckle assemblies 23 should be arranged in a symmetrical form to evenly apply force to the dismounting disc 41.

[0062] It is to be noted that the relational terms herein, such as first and second, and the like, are used solely to distinguish one from another entity or action without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
