Disclosure of Invention

The invention provides a dust remover, and aims to solve the technical problem of how to provide another dust remover.

The technical problem to be solved by the invention can be realized by the following technical scheme: a dust remover comprises a box body and a clapboard with an air passing hole, wherein the outer edge part of the clapboard is fixedly connected with the wall of the box body in a sealing way; a filter cartridge is arranged in a chamber on one horizontal side of the partition board in the box body, and an air outlet is formed in the top wall of the chamber; a filter screen frame is arranged in a chamber on the other horizontal side of the partition board in the box body, and an air inlet is formed in the wall of the chamber; the filter screen frame is fixed with a filter screen, the top of the filter screen frame is rotatably connected with the partition plate or the wall of the box body, the filter screen frame can automatically depend on the partition plate under the action of gravity, when the filter screen frame depends on the partition plate, the filter screen is opposite to the air inlet, and the filter screen frame is in an inclined state.

When the dust remover is used, the air inlet is communicated with the dust collection cover, and the air outlet is connected with the fan. The dust remover also comprises a back-blowing mechanism for back-blowing and ash-removing the filter cylinder by utilizing compressed air. When the fan operates, airflow containing dust enters the inner cavity of the box body from the air inlet, the dust is filtered by the filter screen at first, and the filter screen can be flexibly selected according to the actual working condition, for example, when the fan is used for separating dust with thicker meshes, the filter screen with thicker meshes can be selected; when the polishing wax is used for separating dust containing polishing wax, a filter screen with a fine mesh can be selected; therefore, the filter screen can obviously reduce the load of the filter cylinder, prolong the service life of the filter cylinder and prolong the interval time of back flushing and dust removing, thereby reducing the consumption of compressed air.

During back flushing and dust cleaning, the dust separated from the filter cylinder is downward in the settling direction, and the airflow moves horizontally, namely the settling direction of the dust is different from the movement direction of the airflow, so that the dust settling rate is effectively improved, in other words, the amount of dust adsorbed back to the surface of the filter cylinder is obviously reduced, the back flushing and dust cleaning interval time is prolonged, and the consumption of compressed air is further reduced.

The air flow for back flushing and dust cleaning simultaneously impacts the filter screen to force the dust adhered on the filter screen to fall off; if the meshes of the filter screen are fine or the amount of the adsorbed dust is large, the filter screen frame is forced to swing, namely the filter screen frame is separated from the partition plate, and then the filter screen frame is flapped on the partition plate under the action of gravity and air flow, so that the falling amount of the dust adhered to the filter screen is obviously increased. This structure guarantees effectively that the filter screen separation dust lasts and high-efficient.

Compared with the prior art, the invention provides a dust remover with another structure. The dust remover adopts the filter screen to pre-filter, and the filter screen can be flexibly selected according to the working condition, thereby ensuring the universality of the dust remover.

When the dust remover is applied to a fiber wheel and polishing wax in the polishing process, a filter screen capable of effectively filtering fibers or waxy substances is selected, the fibers and the waxy substances are obviously reduced to be adsorbed on the filter cylinder, and the service life of the filter cylinder is obviously prolonged. The filter screen has low price's characteristic, and then can in time change the filter screen according to fibre and waxy material adsorption capacity, guarantees the filter efficiency of filter screen.

The filter screen also has the characteristic of small resistance, so that the filter screen hardly increases the resistance of the dust remover; meanwhile, the filter screen can obviously improve the dust removal efficiency of the dust remover, prolong the service life of the filter cylinder and reduce the operating cost of the dust remover.

When the filter cartridge is subjected to back blowing for deashing, dust adhered to the filter screen is also cleaned, so that the filtering efficiency of the filter screen is ensured; therefore, the dust remover has the advantage of convenient operation and management.

Example one

As shown in fig. 1 to 3, the dust collector includes a housing 1, a partition 2, a filter cartridge 3, a filter frame 4, and a filter screen 5.

The box body 1 is a basic piece and can be placed on the ground. For convenience of description, the cabinet 1 is defined as a bottom of the cabinet 1 and a top of the cabinet 1 in a vertical direction; the partition plate 2, the filter cartridge 3, the filter screen frame 4 and the filter screen 5 are all arranged at the top of the inner cavity of the box body 1; the number of the partition plates 2 is two, the partition plates 2 are vertically arranged, the outer edge parts of the partition plates 2 are fixedly connected with the wall of the box body 1 in a sealing manner, and the top part of the box body 1 is divided into a left air inlet cavity 1a, a dust removing cavity 1b and a right air inlet cavity 1a by the partition plates 2 along the left-right direction shown in the figure 1; the clapboard 2 is provided with an air inlet 1a communicated with the dust removing cavity 1 b.

The filter cartridge 3 is arranged in the dust removing cavity 1b, and the top wall of the dust removing cavity 1b is provided with an air outlet; the top surface of the box body 1 is provided with a fan 6 communicated with the air outlet, the outer side of the fan 6 is provided with a sound-proof shield 7, and the sound-proof shield 7 is fixedly connected with the box body 1. The box body 1 is provided with a back-blowing mechanism 8 which can utilize compressed air to back-blow and clean ash the filter cartridge 3, and the back-blowing mechanism 8 comprises a compressed air storage tank 8a fixed on the outer side surface of the box body 1, an air pipe 8b communicated with the inner cavity of the filter cartridge 3 and the compressed air storage tank 8a and a valve 8c connected in series on the air pipe 8 b.

The filter screen frame 4 is plate-shaped and is positioned in the air inlet cavity 1a, and the partition plate 2 is positioned between the filter screen frame 4 and the filter cartridge 3; the filter screen 5 is fixed on the filter screen frame 4 through a detachable structure, so that the filter screen 5 is convenient to replace. The top of the filter screen frame 4 is rotatably connected with the partition board 2 or the wall of the box body 1 through the hinge 9, so that the filter screen frame 4 can horizontally swing, the filter screen frame 4 can automatically depend on the partition board 2 under the action of gravity, and the filter screen 5 is right opposite to the air inlet when the filter screen frame 4 depends on the partition board 2. The outer fringe part of filter screen frame 4 or the face of leaning on of baffle 2 are pasted and are equipped with the sealing strip, and the sealing strip has improved the leakproofness between filter screen frame 4 and the baffle 2 when filter screen frame 4 relies on baffle 2 notably, avoids the air current to pass through from the clearance between filter screen frame 4 and the baffle 2 promptly. The filter screen frame 4 is in an inclined state when the filter screen frame 4 is leaned on the partition plate 2, the structure can improve the sealing property between the filter screen frame 4 and the partition plate 2 and avoid the filter screen frame 4 from swinging under the action of air flow generated by the fan 6; specifically, the partition plate 2 has an abutting surface on which the screen frame 4 abuts and is disposed obliquely.

The left side and the right side of the filter cylinder 3 can be supplied with air, so that the use uniformity of the filter cylinder 3 is ensured, and the service life of the filter cylinder 3 is further utilized. Simultaneously, a dust collecting cavity 1c is arranged below the left air inlet cavity 1a and the right air inlet cavity 1a, the arrangement structure is matched with the structure of the existing polishing vehicle, and the polishing wheels 11 arranged at the two ends of the polishing vehicle are all positioned in the dust collecting cavities 1c by controlling the distance between the two dust collecting cavities 1 c.

For convenience of description, the case 1 is also defined as a left portion of the case 1, a middle portion of the case 1, and a right portion of the case 1 in the left-right direction shown in fig. 1; the cabinet 1 is defined as a rear portion of the cabinet 1 and a front portion of the cabinet 1 in the left-right direction shown in fig. 2. The two dust collecting cavities 1c are respectively positioned at the left front part and the right front part of the bottom 1h of the box body; the walls of the front parts of the two dust collecting chambers 1c are provided with polishing operation ports 1 d. The area between the two dust collecting cavities 1c is a mounting and avoiding space of the polishing vehicle.

The rear side of the bottom of the box body 1 is a sedimentation chamber 1e, namely the sedimentation chamber 1e is positioned at the rear side of the dust collection chamber 1 c; the two air inlet cavities 1a are communicated with the sedimentation cavity 1 e. The settling chamber 1e and the dust collecting chamber 1c are separated by a vertical plate 1 f. The bottom wall 1c1 of the dust collection chamber 1c is arc-shaped, the front end of the bottom wall 1c1 extends to the front wall of the dust collection chamber 1c, the rear end of the bottom wall 1c1 extends to the position right below the vertical plate 1f, and the front end of the bottom wall 1c1 of the dust collection chamber 1c is higher than the rear end. An air passing channel 1g is arranged between the lower edge of the vertical plate 1f and the bottom wall 1c1, and the width of the air passing channel 1g is the same as that of the dust collection cavity 1 c. The bottom surface of the settling chamber 1e is positioned lower than the bottom wall 1c1 of the dust collecting chamber 1 c.

A control plate 10 which can enable the bottom of the dust removing cavity 1b and the sedimentation cavity 1e to be in a communicated state or a cut-off state is arranged in the box body 1. Specifically, one edge of the control panel 10 is pivotally connected to the wall of the case 1 by a hinge 9, and a lock is provided between the other edge of the control panel 10 and the wall of the case 1. When the dust remover is in an operating state, the control panel 10 enables the bottom of the dust removing cavity 1b and the settling cavity 1e to be in a cut-off state, and prevents air flow from directly entering the dust removing cavity 1b from the bottom of the dust removing cavity 1b through the settling cavity 1 e. Meanwhile, when the filter cylinder 3 is in a back-blowing ash-cleaning state, the dust settling movement direction is different from the air flow direction.

The function and the beneficial effect of each technical characteristic are further explained by explaining the operation process of the dust remover. The fan 6 operates to enable the dust collection cavity 1c to generate negative pressure, air in the air inlet cavity 1a is forced to enter the dust collection cavity 1c through the filter screen 5 and the air passing opening, air in the sedimentation cavity 1e enters the air inlet cavity 1a, air in the dust collection cavity 1c enters the sedimentation cavity 1e through the air passing channel 1g, and outside air enters the dust collection cavity 1c through the polishing control opening 1d, so that air flow flowing from the polishing control opening 1d to the air outlet is formed.

Because the bottom wall 1c1 of the dust collection chamber 1c is arc-shaped, the air passing channel 1g is adjacent to the bottom wall 1c1, and the width of the air passing channel 1g is the same as that of the dust collection chamber 1c, the airflow at the bottom of the dust collection chamber 1c moves along the plate surface of the bottom wall 1c1 until entering the sedimentation chamber 1 e; in the process, the airflow moves in an arc-shaped track line, the airflow flows smoothly, no part blocks the airflow, and the backflow phenomenon cannot be generated.

An operator or robot holds the workpiece against the face of the polishing wheel 11. The wheel surface of the polishing wheel 11 rotating at a high speed rubs with the surface of the workpiece, and polishing is further realized. The generated dust moves along the tangent line of the polishing wheel 11, and the bottom wall 1c1 of the dust collection chamber 1c is arc-shaped, so that the included angle between the tangent line and the bottom wall 1c1 of the dust collection chamber 1c is larger than the included angle between the tangent line and the horizontal plane; in other words, the dust flow direction and the air flow direction are more gentle, the dust flows along with the air flow more easily, and the reverse flow phenomenon formed on the air guide surface by the dust air flow impact is obviously reduced.

The dust enters the sedimentation chamber 1e through the air passage 1g along with the air flow, and the cross section area of the sedimentation chamber 1e is far larger than that of the air passage 1g, so that the air flow speed is greatly reduced, and the large-particle dust and the polishing wheel 11 debris are naturally settled.

Because the bottom surface of the settling chamber 1e is lower than the bottom wall 1c1 of the dust collection chamber 1c, the influence of dust accumulated on the bottom surface of the settling chamber 1e on the air flow is avoided, and the backflow of dust accumulated in the settling chamber 1e to the polishing wheel 11 installation chamber and the outflow of dust in the polishing wheel 11 installation chamber from the polishing operation port 1d are avoided.

When the airflow passes through the filter screen 5, the large particle dust and the polishing wheel 11 debris are filtered again, in other words, the airflow entering the dust removing chamber 1b contains finer dust particles. The dust is filtered by the filter drum 3 and then the clean air is discharged from the air outlet.

The blowback mechanism 8 carries out the blowback deashing to straining a section of thick bamboo 3 according to setting for the interval duration, opens valve 8c, and compressed air spouts in straining a section of thick bamboo 3 in the twinkling of an eye, forces the air current to flow backward, and then the dust of adsorbing on straining a section of thick bamboo 3 surface is blown up, and the dust subsides downwards under the action of gravity, and the dust subsides promptly on control panel 10. In the process, the back-flushing airflow simultaneously forces the dust adsorbed on the filter screen 5 to fall off, even forces the filter screen frame 4 to swing, and after the back-flushing airflow is stopped, the filter screen frame 4 impacts the partition board 2 under the action of gravity, so that the dust falling amount on the filter screen 5 is increased; the filtering efficiency of the filter screen 5 is ensured.

After the dust remover stops operating, the lock can be opened, so that dust settled on the control panel 10 falls into the settling chamber 1e, and the dust is accumulated together, thereby facilitating the subsequent centralized cleaning.
