Description

Technical Field

[0001] The utility model relates to the technical field of air separation and purification, in particular to a built-in rotatable filter barrel. Background Art

[0002] At present, maintaining the purity of materials is an important part of process production, especially in air separation. After the air passes through the adsorbent in the purifier, impurities such as moisture and carbon dioxide are well removed, but dust is produced by the wear of the adsorbent. In order to ensure the purity of the material, a filter barrel must be set at the outlet of the purifier to prevent dust from entering the downstream process and clogging the equipment.

[0003] In order to ensure the filtering efficiency and pressure drop of the equipment, the corresponding filtering area needs to be designed. The conventional external suspended filter barrel will have a long invalid filtering area in the pipe, which needs to be lengthened or the pipe size increased to meet the requirements, which has a great impact on the equipment. Utility Model Content

[0004] In order to solve the technical problem that the conventional external suspended filter barrel has a long invalid filtering area in the pipe, which requires lengthening the filter barrel or increasing the size of the pipe to meet the requirement, and has a relatively large impact on the equipment, the utility model provides a built-in rotatable filter barrel.

[0005] The utility model is implemented by the following technical scheme: a built-in rotatable filter barrel, comprising a container, the top of the container is connected to a connecting pipe, a rotating shaft is rotatably installed inside the container, and a head is fixedly installed on the top of the container, both sides of the rotating shaft are fixedly connected with filter barrels corresponding to the connecting pipe, a motor is fixedly installed on the top of the head, the output end of the motor is connected to the top of the head through a transmission assembly and the rotating shaft passes through the head, the connecting pipe and the filter barrel are connected by a snap mechanism, and the snap mechanism is used for the connecting pipe and the filter barrel to dock, seal and limit the filtering of dust.

[0006] Through the above technical solution, the filter barrel can be rotated to the other side by rotating it, and the pipe can be used as a manhole, reducing the number of openings on the container. In addition, the internal space of the container is large, and the height of the filter barrel can be reduced by increasing the diameter of the filter barrel, thereby reducing the total height of the container.

[0007] As a further improvement of the above solution, the snap mechanism includes an insert block slidably connected to the inner side of the bottom of the pipe, the insert block can slide up and down at the bottom of the pipe, and a limiting hole is provided inside the insert block.

[0008] As a further improvement of the above scheme, the snap mechanism also includes a clamping block fixedly installed on the inner side of the top of the filter barrel and used in conjunction with the plug block, a limiting groove corresponding to the plug block is opened inside the clamping block, and a fixing plate is arranged inside the clamping block, and a limiting rod corresponding to the limiting hole is slidably connected to the inside of the fixing plate.

[0009] Through the above technical solution, the insert block slides into the limiting groove, thereby squeezing the limiting rod. When the limiting rod is inserted into the limiting hole, the limiting fixation is completed, and the fixing is automatically completed for filtering, thereby improving work efficiency.

[0010] As a further improvement of the above solution, a slide groove is provided on the top of the block, a slider is slidably connected inside the slide groove, the slider is fixedly connected to one end of the limit rod, and one side of the slider is connected to the output end of the cylinder.

[0011] Through the above technical solution, when the limit with the pipe is released, the cylinder pushes the slider to move, so that the limit rod is separated from the limit hole.

[0012] As a further improvement of the above solution, the transmission assembly includes pulleys connected to the output end of the motor and the top of the rotating shaft respectively, and the transmission is performed between the two pulleys through a belt.

[0013] As a further improvement of the above solution, a mounting groove is provided inside the filter barrel, a support block of the filter element is slidably connected inside the mounting groove, and a mounting seat is fixedly connected to the top of the filter element.

[0014] Through the above technical solution, the filter element is inserted and installed in the filter barrel, which is convenient for disassembly of the filter element, thereby facilitating the repair and maintenance of the filter element.

[0015] As a further improvement of the above solution, when the inserting block slides up into the connecting pipe, the filter barrel can be rotated to the other side of the connecting pipe, and the connecting pipe forms a manhole.

[0016] When the connecting pipe is used as a manhole, the worker enters the connecting pipe, and after the slider releases the limit of the limit rod, the slider is pulled back upwards, so that the filter barrel rotates to the other side of the connecting pipe, and the connecting pipe forms a manhole.

[0017] As a further improvement of the above solution, a rubber sealing ring is provided at the bottom of the connecting pipe.

[0018] Through the above technical solution, the sealing ring squeezes the connecting pipe and the filter barrel when they are connected, so that the connecting pipe and the filter barrel are sealed.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model rotates the filter barrel so that the insert block is stuck in the limit groove, and the slide block is pushed to slide in the slide groove by the cylinder, driving the limit rod to be inserted into the limit hole. When the limit rod is inserted into the limit hole, the limit fixation is completed for filtering, and the filtered gas is discharged from the connecting pipe. When the connecting pipe is used as a manhole, the staff enters the connecting pipe, and after the slider releases the limit of the limit rod, the slider is pulled back upwards, and then the motor works to drive the filter barrel to rotate to the other side of the connecting pipe to form a manhole. The present design is set to be a rotatable filter barrel, which can make the connecting pipe also serve as a manhole, reduce the number of holes on the container, and at the same time, the built-in filter barrel can increase the diameter, reduce the height of the filter barrel, and reduce the total height of the container.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0031] Please combine Figure 1 - Figure 6A built-in rotatable filter barrel of the present embodiment includes a container 1, a connecting pipe 3 is connected to the top of the container 1, a rotating shaft 4 is rotatably installed inside the container 1, and a head 2 is fixedly installed on the top of the container 1, and filter barrels 7 corresponding to the connecting pipe 3 are fixedly connected on both sides of the rotating shaft 4, and a motor 5 is fixedly installed on the top of the head 2, and the output end of the motor 5 is connected to the top of the head 2 through the rotating shaft 4 through the transmission assembly 6. The connecting pipe 3 and the filter barrel 7 are connected by a snap mechanism, and the snap mechanism is used for the connecting pipe 3 and the filter barrel 7 to dock, seal and limit the dust.

[0032] By rotating the filter barrel 7, the filter barrel 7 can be rotated to the other side, and the pipe 3 can be removed and used as a manhole, thereby reducing the number of openings on the container 1. The internal space of the container 1 is large, and the height of the filter barrel 7 can be reduced by increasing the diameter of the filter barrel 7, thereby reducing the overall height of the container 1.

[0033] Please combine Figure 3 The buckle mechanism includes an insert block 9 which is slidably connected to the inner side of the bottom of the pipe 3 , and a limiting hole 10 is provided inside the insert block 9 .

[0034] Please combine Figure 3 and Figure 4 The buckle mechanism also includes a block 11 fixedly installed on the inner side of the top of the filter barrel 7 and used in conjunction with the plug block 9. A limiting groove 12 corresponding to the plug block 9 is opened inside the block 11, and a fixing plate 13 is arranged inside the block 11. A limiting rod 14 corresponding to the limiting hole 10 is slidably connected to the inside of the fixing plate 13.

[0035] The insert block 9 slides into the limiting groove 12, thereby squeezing the limiting rod 14. When the limiting rod 14 is inserted into the limiting hole 10, the limiting fixation is completed, and the fixing is automatically completed for filtering, thereby speeding up the work efficiency.

[0036] Please combine Figure 4 A slide groove 17 is provided at the top of the block 11, and a slider 16 is slidably connected inside the slide groove 17. The slider 16 is fixedly connected to one end of the limit rod 14, and one side of the slider 16 is connected to the output end of the cylinder 8.

[0037] When the limit with the connecting pipe 3 is released, the cylinder pushes the slider 16 to move, so that the limit rod 14 is separated from the limit hole 10.

[0038] Please combine Figure 1 The transmission assembly 6 includes pulleys connected to the output end of the motor 5 and the top of the rotating shaft 4 respectively, and the transmission is carried out between the two pulleys through a belt.

[0039] Please combine Figure 5 A mounting groove 18 is provided inside the filter barrel 7 , a support block 21 of a filter element 19 is slidably connected inside the mounting groove 18 , and a mounting seat 20 is fixedly connected to the top of the filter element 19 .

[0040] The filter element 19 is inserted and installed in the filter barrel 7, which is convenient for disassembly of the filter element 19 and thus for repair and maintenance of the filter element 19.

[0041] Please combine Figure 2 When the insert block 9 slides up into the connecting pipe 3, the filter barrel 7 can be rotated to the other side of the connecting pipe 3, and the connecting pipe 3 forms a manhole.

[0042] When the pipe 3 is used as a manhole, a worker enters the pipe 3 and pulls the slider 9 back upward after the slider 9 releases the limit of the limit rod 14, so that the filter barrel 7 rotates to the other side of the pipe 3, and the pipe 3 forms a manhole.

[0043] Please combine Figure 4 A rubber sealing ring 15 is provided at the bottom of the connecting pipe 3.

[0044] When the connecting pipe 3 is connected to the filter barrel 7 , the sealing ring 15 squeezes the connecting pipe 3 and the filter barrel 7 so that the connecting pipe 3 and the filter barrel 7 are sealed.

[0045] The implementation principle of a built-in rotatable filter barrel in the embodiment of the present application is as follows: when working, gas enters from the container 1 and passes into the filter barrel 7, and the motor 5 drives the rotating shaft 4 to rotate through the transmission assembly 6. When the rotating shaft 4 rotates, the filter barrel 7 rotates, so that the insert block 9 is stuck in the limiting groove 12, and the slider 16 is pushed by the cylinder 8 to slide in the slide groove 17, driving the limiting rod 14 to insert into the limiting hole 10. When the limiting rod 14 is inserted into the limiting hole 10, the limiting fixation is completed for filtering, and the filtered gas is discharged from the connecting pipe 3. When the connecting pipe 3 is used as a manhole, the cylinder 8 pulls back the limiting rod 14, so that the limiting rod 14 is separated from the limiting hole 10. When the connecting pipe 3 is used as a manhole, the staff enters the connecting pipe 3, and after the slider 9 releases the limiting of the limiting rod 14, the slider 9 is pulled back upwards, and then the motor 5 works to drive the filter barrel 7 to rotate to the other side of the connecting pipe 3 to form a manhole.

[0046] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
