[0005] A plurality of installation holes one are formed in the installation plane, a plurality of installation holes two are formed in the lower wall of the closure, and the plurality of installation holes one and the plurality of installation holes two are one-to-one corresponding.

[0006] The filtering mechanism further comprises a plurality of filtering devices, the plurality of filtering devices are one-to-one corresponding to the plurality of installation holes one, the filtering device comprises an installation sleeve, the installation sleeve is threadedly connected to the installation hole one and the installation hole two from top to bottom, an air hole is formed in the side wall of the installation sleeve in the flow-through cavity, a support is detachably installed in the installation sleeve below the air hole, a dust removal cloth bag is installed on the support, and a cover is detachably installed on the top of the installation sleeve.

[0007] A baffle is arranged directly below the closure, and the baffle is fixed to the closure or the storage tank.

[0008] By adopting the above scheme, the airflow carrying the material moves along the material area to the filtering area, and after reaching the filtering area, the airflow enters the installation sleeve, and the dust removal cloth bag in the installation sleeve filters the airflow, and then enters the flow cavity through the air hole and is sucked away by the air compressor. In this process, when it is found that the dust removal cloth bag is blocked by powder and affects normal work, the worker screws the installation sleeve so that the installation sleeve abuts against the baffle, at this time the baffle closes the bottom of the installation sleeve, the air hole is located in the installation hole two so that the air hole is closed, and then the installation sleeve is closed. The worker can open the cover at the top of the installation sleeve, take out the support and replace the dust removal cloth bag. In this case, it will not interfere with the normal work of other filtering devices, so as to realize the replacement of the dust removal cloth bag without affecting the normal work of the pressure delivery vehicle. Further, the cover is made of transparent material.

[0012] A plurality of insertion slots are formed in the inner circumferential surface of the installation sleeve, and a plurality of the insertion slots correspond to a plurality of the plug rods one by one, and the plug rod extends into the insertion slot under the action of the elastic member.

[0013] By adopting the above scheme, the plug rod extends into the insertion slot under the action of the elastic member, and the support can be detachably fixed in the installation sleeve.

[0014] Further, a plurality of sliding grooves are formed in the inner wall of the installation sleeve, and a plurality of the sliding grooves correspond to a plurality of the insertion slots one by one, and the sliding groove is located below the insertion slot and communicates with the insertion slot.

[0015] A push rod is in sliding connection in the sliding groove, the top end of the push rod is provided with a pushing inclined surface, and the bottom end of the push rod extends out of the sliding groove under the action of gravity, and when the installation sleeve abuts against the baffle, the push rod pushes the plug rod out of the insertion slot.

[0021] By adopting the above scheme, the hook is hooked into the hanging hole by sliding the adjusting rod up and down, so as to limit the insertion rod. In this way, the friction between the insertion rod and the inner wall of the mounting sleeve can be reduced as much as possible during the process of taking out the bracket from the mounting sleeve, so that the bracket is more easily taken out from the mounting sleeve.

[0022] Further, an arc-shaped surface is arranged at a side of the insertion rod facing the push rod.

[0023] By adopting the above scheme, the insertion rod is pushed to be separated from the insertion slot by the top-pushing inclined surface.

[0024] Further, the hook is located directly below the hanging hole.

[0025] By adopting the above scheme, because the bracket is in a working state (i.e. installed in the mounting sleeve) for a longer time than the time when the bracket needs to be taken out from the mounting sleeve, that is, the time when the insertion rod extends into the insertion slot accounts for a larger proportion than the time when the insertion rod is separated from the insertion slot, so in this case, when the hanging hole is aligned with the hook, the hanging hole is located directly below the hook. In this way, when the bracket needs to be initially taken out from the mounting sleeve, the adjusting rod can be slid upward to make the hook hooked into the hanging hole. When the bracket needs to be installed in the mounting sleeve, the insertion rod is aligned with the insertion slot, at this time the adjusting rod is loosened and pushed downward to make the hook separated from the hanging hole, at this time the insertion rod enters into the insertion slot, and the operation is more simple and convenient.

[0043] The filtering mechanism further comprises a plurality of filtering devices 4, which are in one-to-one correspondence with the plurality of mounting holes 251. Specifically, the filtering device 4 comprises a circular mounting sleeve 41, which penetrates the mounting hole 251 and the mounting hole 32 and is threadedly connected to the mounting hole 251 and the mounting hole 32. The mounting sleeve 41 is closed at the top and open at the bottom.

[0044] With reference to Figure 4 , specifically, the mounting sleeve 41 is detachably provided with a cover 42 at the top, which realizes the closure of the top of the mounting sleeve 41. Specifically, the cover 42 is a downwardly open shell body matched with the mounting sleeve 41. The cover 42 is fixed to the mounting sleeve 41 by screws. In order to facilitate the observation of the working condition of the dust removal cloth bag 44 in the mounting sleeve 41 by the workers, the cover 42 is made of transparent material, such as glass.

[0045] With reference to Figure 3 and Figure 4 , a plurality of air vents 411 are formed in the mounting sleeve 41 and located in the flow cavity 31.

[0046] With reference to Figure 4 and Figure 5 , a bracket 43 is detachably installed in the mounting sleeve 41 and located below the air vent 411. The dust removal cloth bag 44 is sleeved on the bracket 43.

[0047] With reference to Figure 3 , a long strip-shaped baffle 5 is arranged below the mounting hole 32 of the closure 3 in the storage tank 2. The baffle 5 is arranged horizontally along the width direction of the storage tank 2 and is fixed to the storage tank 2 or the closure 3.

[0048] The airflow carrying the material moves along the material area 23 to the filtering area 24. After reaching the filtering area 24, the airflow enters the mounting sleeve 41. The dust removal cloth bag 44 in the mounting sleeve 41 filters the airflow. Then, the airflow enters the flow cavity 31 through the air vent 411 and is drawn away by the air compressor. In this process, when it is found that the dust removal cloth bag 44 is blocked by powder and affects the normal work, the worker screws the mounting sleeve 41 so that the mounting sleeve 41 abuts against the baffle 5. At this time, the baffle 5 closes the bottom of the mounting sleeve 41. The air vent 411 is located in the mounting hole 32, so that the air vent 411 is closed, and the mounting sleeve 41 is closed. The worker can open the cover 42 at the top of the mounting sleeve 41, take out the bracket 43, and replace the dust removal cloth bag 44. In this case, it will not interfere with the normal work of other filtering devices 4, so that the replacement of the dust removal cloth bag 44 is realized without affecting the normal work of the pressure delivery vehicle.

[0049] Further, with reference to Figure 4 and Figure 5The bracket 43 comprises a circular connecting plate 431 matched with the mounting sleeve 41, the connecting plate 431 is coaxially arranged in the mounting sleeve 41, and the connecting plate 431 is in sliding connection with the mounting sleeve 41, and the lower portion of the connecting plate 431 is fixedly connected with a frame body 432 matched with the dust removal cloth bag 44. The dust removal cloth bag 44 is sleeved to the frame body 432, and the dust removal cloth bag 44 is detachably connected with the frame body 432. Specifically, the dust removal cloth bag 44 and the frame body 432 are connected by screws or the like.

[0050] Referring to Figure 6 A plurality of arrangement holes 4311 are horizontally formed on the outer circumferential surface of the connecting plate 431, and a plug rod 433 is in sliding connection in the arrangement hole 4311, and an elastic member is fixedly connected between the plug rod 433 and the connecting plate 431. The elastic member is generally selected to be a spring. Specifically, a groove is formed on the inner wall of the arrangement hole 4311, and the elastic member is hidden in the groove.

[0051] Referring to Figure 7 and Figure 8 A plurality of plug slots 412 matched with the plug rod 433 are formed on the inner wall of the mounting sleeve 41, and the plurality of plug slots 412 correspond to the plurality of arrangement holes 4311 one by one. The plug rod 433 is extended into the plug slot 412 under the action of the elastic member, so as to realize detachable fixing of the bracket 43 in the mounting sleeve 41. During replacement of the dust removal cloth bag 44, first, the mounting sleeve 41 is abutted against the baffle 5, then the cover body 42 is opened, the plug rod 433 is actuated to make the plug rod 433 disengage from the plug slot 412, and then the bracket 43 is dismounted from the mounting sleeve 41 for replacement of the dust removal cloth bag 44.

[0052] Further, a plurality of sliding grooves 413 are vertically formed on the inner wall of the mounting sleeve 41, the plurality of sliding grooves 413 correspond to and communicate with the plurality of plug slots 412 one by one, the sliding groove 413 is located below the plug slot 412, and the width of the sliding groove 413 is smaller than the width of the plug slot 412. The cross section of the sliding groove 413 is dovetail type. A push rod 414 is in sliding connection in the sliding groove 413, and a top pushing inclined surface 4141 is arranged at the top end of the push rod 414. The bottom end of the push rod 414 is extended out of the sliding groove 413 under the action of gravity.

[0053] During movement of the mounting sleeve 41 to the baffle 5, the push rod 414 is pushed to move upward, and when the mounting sleeve 41 is abutted against the baffle 5, the top pushing inclined surface 4141 at the top end of the push rod 414 pushes the plug rod 433 out of the plug slot 412, so as to facilitate dismounting of the bracket 43.

[0054] The push rod 414 and the mounting sleeve 41 are fixedly connected with an elastic member. Specifically, a recess is vertically formed in the sliding groove 413, and the elastic member is hidden in the recess. The action of the elastic member can assist the bottom end of the push rod 414 to extend downward out of the sliding groove 413, and simultaneously stably mount the push rod 414 in the sliding groove 413.

[0055] In order to facilitate the pushing slope 4141 to push the plug rod 433 to disengage from the insertion slot 412, the plug rod 433 is provided with an arc surface 4332 towards one side of the push rod 414.

[0056] Referring to Figure 4 Further, the cover 42 and the bracket 43 are fixedly connected with the connecting rod 6. After the mounting sleeve 41 is abutted to the baffle 5, the push rod 414 pushes the plug rod 433 out of the insertion slot 412. At this time, the cover 42 is removed from the mounting sleeve 41, and the cover 42 can take out the bracket 43.

[0057] Referring to Figure 9 The top end of the connecting rod 6 extends upwardly out of the cover 42. A coaxial assembly hole 61 is formed in the connecting rod 6. The assembly hole 61 can be circular, square, triangular, etc. In the case, the square is selected. An adjusting rod 7 which is adapted to the assembly hole 61 is slidably connected in the assembly hole 61.

[0058] Referring to Figure 9 A plurality of long strip-shaped connecting holes 62 are vertically formed in the connecting rod 6 located in the mounting sleeve 41. The plurality of connecting holes 62 correspond to the plurality of arrangement holes 4311 one by one. A hook 71 is slidably connected in the connecting hole 62, and the hook 71 is fixed to the adjusting rod 7.

[0059] Referring to Figure 8 The end of the arrangement hole 4311 away from the insertion slot 412 extends to the inner circumferential surface of the connecting plate 431. The end of the plug rod 433 away from the insertion slot 412 is provided with a hanging hole 4331. The axis of the hanging hole 4331 is vertical. When the pushing slope 4141 on the push rod 414 pushes the plug rod 433 out of the insertion slot 412, the hanging hole 4331 is aligned with the hook 71. At this time, the hanging hole 4331 is located directly above or below the hook 71. By sliding the adjusting rod 7 up and down, the hook 71 can be hooked into the hanging hole 4331 to limit the plug rod 433. In this way, during the process of taking out the bracket 43 from the mounting sleeve 41, the friction between the plug rod 433 and the inner wall of the mounting sleeve 41 can be reduced as much as possible, so that the bracket 43 is more easily taken out from the mounting sleeve 41.

[0060] Further, because the time that the bracket 43 is in the working state (i.e. the state of being installed to the installation sleeve 41) is longer than the time that the bracket 43 needs to be taken out from the installation sleeve 41, i.e. the time that the insertion rod 433 extends into the insertion slot 412 is longer than the time that the insertion rod 433 is separated from the insertion slot 412, so in this case, when the hanging hole 4331 is aligned with the hook 71, the hanging hole 4331 is located directly below the hook 71. In this way, when the bracket 43 needs to be taken out of the installation sleeve 41, the adjusting rod 7 can be slid upward to make the hook 71 hook to the hanging hole 4331. When the bracket 43 needs to be installed to the installation sleeve 41, the insertion rod 433 is aligned with the insertion slot 412, at this time, the adjusting rod 7 is loosened and pushed downward to make the hook 71 separate from the hanging hole 4331, at this time, the insertion rod 433 enters into the insertion slot 412, the operation is more simple and convenient.

[0061] The implementation principle of the present application is that the airflow carrying the material moves along the material area 23 to the filtering area 24, the airflow enters the installation sleeve 41 after reaching the filtering area 24, the dust removal cloth bag 44 in the installation sleeve 41 filters the airflow, and then enters the flow-through cavity 31 through the air vent 411 and is drawn away by the air compressor. In this process, when it is found that the dust removal cloth bag 44 is blocked by powder and affects normal work, the worker screws the installation sleeve 41 to make the installation sleeve 41 abut against the baffle 5, at this time, the baffle 5 closes the bottom of the installation sleeve 41, the air vent 411 is located in the installation hole two 32 to make the air vent 411 be closed, and then the installation sleeve 41 is closed. The pushing inclined surface 4141 on the push rod 414 pushes the insertion rod 433 out of the insertion slot 412, the hanging hole 4331 is aligned with the hook 71, the hook 71 is hooked to the hanging hole 4331, and the worker can open the cover 42 at the top of the installation sleeve 41 to take out the bracket 43 to replace the dust removal cloth bag 44. In this way, the replacement of the dust removal cloth bag 44 can be realized without affecting the normal work of the pressure delivery vehicle.

[0062] The embodiments of the specific implementation are the preferred embodiments of the present application, but do not limit the protection scope of the present application, wherein the same parts are indicated by the same reference numerals. Therefore: all effective changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
