Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cyclone dust collection and material suction machine, and particularly relates to a cyclone dust collection and material suction machine. Background Technology
[0002] Cyclone dust collectors primarily rely on centrifugal force and gravity to separate dust from gas through a rotating airflow. When dust-laden gas enters the cyclone dust collector through its inlet pipe (usually tangentially), the airflow is influenced by guide plates or cyclones, initiating a rotating motion along the cylindrical wall. This rotational motion is called an external vortex, and its direction is determined by the design of the inlet pipe. During this rotation, dust particles in the airflow, due to inertia, are gradually moved towards the outer wall by centrifugal force. The magnitude of the centrifugal force is directly proportional to the tangential velocity of the airflow; therefore, the faster the rotation speed, the greater the centrifugal force on the dust particles, and the easier it is for them to be thrown towards the wall. Dust particles reaching the wall then move downwards along the wall under the combined action of the airflow and gravity, eventually settling in the bottom ash hopper.
[0003] When the dust collection box of a cyclone dust collector is removed during operation, the lower opening is opened, and the residual dust inside leaks out in large quantities along with the downward-discharged gas, causing the conventional cyclone dust collector to easily pollute the surrounding environment when opened during operation.
[0004] Therefore, we propose a cyclone dust collection and material suction machine to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that conventional cyclone dust collection and material suction machines easily pollute the surrounding environment when opened during operation, and to propose a cyclone dust collection and material suction machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cyclone dust collector includes a cyclone dust collector body. An automatic closing valve is fixedly connected to the lower part of the cyclone dust collector body. The automatic closing valve includes a connecting seat, a movable valve plug slidably installed inside the connecting seat, and a fastening sleeve fastened to the outside of the connecting seat. The lower end of the movable valve plug is supported inside the fastening sleeve, and a dust collection box is fixedly connected to the lower end of the fastening sleeve. The upper part of the movable valve plug is sealed and matched with the inner wall of the cyclone dust collector body. Twisting the dust collection box rotates the fastening sleeve, which rotates along the connecting seat until the opening of the connecting seat and the fastening sleeve are aligned. Then, pulling the dust collection box downwards causes the fastening sleeve to disengage from the connecting seat, causing the movable valve plug to descend along the connecting seat and close the lower opening of the cyclone dust collector body. This facilitates automatic shielding of the ash outlet after the dust collection box is removed.
[0008] Preferably, the connecting seat includes a housing, a guide seat, and fastening blocks. The upper end of the housing is fixedly connected to the cyclone dust collector body, the fastening blocks are symmetrically fixedly connected to the outside of the housing, and the movable valve plug is slidably connected to the guide seat. The guide seat slides to guide the movable valve plug to rise and fall, and the fastening blocks engage with the fastening sleeve, facilitating the connection of the connecting seat and the fastening sleeve to be connected or disassembled.
[0009] Preferably, the connecting seat further includes a dust guide block, which is fixedly connected to the upper end of the guide seat. The dust guide block guides the dust downwards, preventing dust from accumulating on the guide seat and facilitating smooth dust discharge from the connecting seat.
[0010] Preferably, the movable valve plug includes a disc and a sliding column. The sliding column is slidably installed within the guide seat and the dust guide block, and the sliding column passes through the guide seat and the dust guide block. The disc is located inside the cyclone dust collector body, and the disc is sealed and matched with the opening of the cyclone dust collector body. When the lower end of the sliding column loses support, the weight of the disc and the sliding column causes the sliding column to slide down along the inside of the guide seat, thereby causing the disc to descend and seal inside the opening of the cyclone dust collector body, facilitating automatic shielding of the opening of the cyclone dust collector body.
[0011] Preferably, the movable valve plug further includes a limiting ring, which is fixedly connected to the lower part of the slide column. The limiting ring stops the slide column at the lower part of the guide seat, preventing it from rising excessively and detaching from the guide seat, thus improving the stability of the sliding connection between the slide column and the guide seat.
[0012] Preferably, the fastener includes a spring clip, a support strip, and a collar. The lower end of the collar is fixedly connected to the upper end of the dust collection box, the support strip is fixedly connected to the inside of the collar, the spring clip is fixedly connected to the upper part of the collar, the support strip is supported by the lower end of the sliding column, the spring clip rests on the fastener block, and the collar is movably fitted onto the outer shell. Rotating the dust collection box causes the collar to rotate, which in turn causes the spring clip to rotate, aligning the fastener block, spring clip, and the opening of the collar. Then, pulling the dust collection box downwards pulls the collar out from under the outer shell, and vice versa, allowing for easy installation and removal of the fastener.
[0013] Preferably, the buckle further includes a hemispherical block, which is fixedly connected to the lower end of the elastic strip. The hemispherical block blocks the side of the buckle block, increasing the resistance to its rotation and improving the stability of the buckle and the connecting seat during docking.
[0014] In summary, the technical effects and advantages of this utility model are as follows:
[0015] 1. Twist the dust collection box to drive the buckle to rotate. The buckle rotates along the connecting seat until the opening of the connecting seat and the buckle are aligned. Then pull the dust collection box down. The dust collection box drives the buckle to disengage from the connecting seat, causing the movable valve plug to descend along the connecting seat. This causes the movable valve plug to close the lower opening of the cyclone dust collector body, making it easy to automatically shield the ash outlet after removing the dust collection box.
[0016] 2. The sliding guide seat guides the movement of the valve plug, and the warm fastener engages with the sleeve, making it easy to connect or disconnect the connecting seat and the sleeve, thus improving practicality.
[0017] 3. Use dust guide blocks to guide the dust downwards, preventing dust from accumulating on the guide seat and facilitating smooth dust discharge from the connecting seat.
[0018] 4. When the lower end of the sliding column loses its support, the weight of the disc and the sliding column causes the sliding column to slide down along the inside of the guide seat, thereby causing the disc to descend and seal the disc inside the opening of the cyclone dust collector body, which facilitates automatic shielding of the opening of the cyclone dust collector body.
[0019] 5. A limit ring is used to stop the slide column at the bottom of the guide seat to prevent it from rising excessively and detaching from the guide seat, thereby improving the stability of the sliding connection between the slide column and the guide seat.
[0020] 6. Rotate the dust collection box to drive the collar to rotate, which in turn drives the spring strip to rotate, aligning the buckle, spring strip, and the opening of the collar. Then pull the dust collection box down to pull the collar out from under the outer shell. Conversely, pull it back to put the buckle back on, making it easy to install and remove the buckle.
[0021] 7. Use a hemispherical block to block the side of the buckle block to increase the resistance to the buckle block turning out and improve the stability of the buckle sleeve and the connecting seat docking state. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.
[0029] Reference Figure 1 and Figure 2 A cyclone dust collection and material suction machine includes a cyclone dust collector body 1. An automatic closing valve 2 is fixedly connected to the lower part of the cyclone dust collector body 1. The automatic closing valve 2 includes a connecting seat 3. A movable valve plug 4 is slidably installed inside the connecting seat 3. A buckle sleeve 5 is fastened to the outside of the connecting seat 3. The lower end of the movable valve plug 4 is supported inside the buckle sleeve 5. A dust collection box 6 is fixedly connected to the lower end of the buckle sleeve 5. The upper part of the movable valve plug 4 is sealed and matched with the inner wall of the cyclone dust collector body 1.
[0030] Reference Figure 1 , 2 The connecting seat 3 includes a housing 31, a guide seat 32, and a fastening block 33. The upper end of the housing 31 is fixedly connected to the cyclone dust collector body 1. The fastening blocks 33 are symmetrically fixedly connected to the outside of the housing 31. The movable valve plug 4 is slidably connected to the guide seat 32. The movable valve plug 4 is raised and lowered by sliding the guide seat 32, and the fastening block 33 is fastened to the fastening sleeve 5.
[0031] Reference Figure 2 and 3 The connecting seat 3 also includes a dust guide block 34, which is fixedly connected to the upper end of the guide seat 32. The dust guide block 34 guides the dust down and prevents dust from accumulating on the guide seat 32.
[0032] Reference Figure 1 , 2 3 and 4, the movable valve plug 4 includes a disc 41 and a sliding column 42. The sliding column 42 is slidably installed in the guide seat 32 and the dust guide block 34, and the sliding column 42 passes through the guide seat 32 and the dust guide block 34. The disc 41 is located inside the cyclone dust collector body 1, and the disc 41 is sealed and matched with the opening of the cyclone dust collector body 1. When the lower end of the sliding column 42 loses support, the weight of the disc 41 and the sliding column 42 causes the sliding column 42 to slide down along the inside of the guide seat 32, thereby causing the disc 41 to descend and seal inside the opening of the cyclone dust collector body 1.
[0033] Reference Figure 2 , 3 In addition to valve 4, the movable valve plug 4 also includes a limiting ring 43, which is fixedly connected to the lower part of the slide column 42. The limiting ring 43 is used to stop the slide column 42 from rising excessively and disengaging from the guide seat 32.
[0034] Reference Figure 1 , 23, 4, and 5, the fastener 5 includes a spring bar 51, a support bar 52, and a collar 53. The lower end of the collar 53 is fixedly connected to the upper end of the dust collection box 6. The support bar 52 is fixedly connected inside the collar 53. The spring bar 51 is fixedly connected to the upper part of the collar 53. The support bar 52 is supported by the lower end of the sliding column 42. The spring bar 51 is blocked on the fastener block 33. The collar 53 is movably fitted onto the outer shell 31. Rotating the dust collection box 6 causes the collar 53 to rotate, which in turn causes the spring bar 51 to rotate, aligning the fastener block 33, the spring bar 51, and the opening of the collar 53. Then, pulling the dust collection box 6 downwards pulls the collar 53 out from under the outer shell 31. Conversely, reinstalling the fastener 5 is done by pulling it back up.
[0035] Reference Figure 2 , 3 And 5, the buckle 5 also includes a hemispherical block 54, which is fixedly connected to the lower end of the elastic bar 51. The hemispherical block 54 is used to block the side of the buckle block 33, increasing the resistance to the buckle block 33 rotating out.
[0036] Working principle: Twisting the dust collection box 6 drives the buckle 5 to rotate. The buckle 5 rotates along the connecting seat 3 until the opening of the connecting seat 3 and the buckle 5 are aligned. Then, the dust collection box 6 is pulled down, and the buckle 5 is disengaged from the connecting seat 3 through the dust collection box 6. This causes the movable valve plug 4 to descend along the connecting seat 3, thereby sealing the lower opening of the cyclone dust collector body 1. This achieves automatic shielding of the ash outlet after the dust collection box is removed.
