Description

Technical Field

[0001] The invention relates to the technical field of powder recovery, in particular to dry mortar dust removal equipment based on powder recovery. Background Art

[0002] The processing of dry mortar includes drying, grinding and other steps. In particular, the drying process produces exhaust gas containing a large amount of smoke and dust. In order to protect the environment, it is necessary to filter the smoke and dust in the exhaust gas. The conventional filtering method is to directly set up a filter screen or filter bag in the exhaust pipe for dust removal.

[0003] For example, the Chinese patent with application number 2015107809685 is specifically a high-efficiency energy-saving dust removal equipment, which utilizes porous, breathable and water-permeable stone, which not only has high compressive strength, low cost and long service life, but also has good water resistance and wear resistance. Applying it in the high-efficiency energy-saving dust removal equipment of the present invention greatly improves the durability of the high-efficiency energy-saving dust removal equipment.

[0004] However, during the actual use of the above-mentioned equipment, when there is a lot of smoke and dust stored on the filter surface or in the filter bag, the filter or filter bag cannot continuously filter the gas, so the entire production process is forced to be interrupted, and the material transportation, mixing and other links have to be stopped and shut down for cleaning. For large-scale dry mortar production companies, every time the equipment is shut down for cleaning, this intermittent production mode undoubtedly causes huge economic losses.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0006] The object of the present invention is to provide a dry mortar dust removal device based on powder recovery to solve the technical defects proposed by the background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dry mortar dust removal device based on powder recovery, comprising a main body box, the main body box is composed of an upper cover shell, a main frame and a lower cover shell;

[0008] A transfer processing cylinder is arranged inside the main frame, a material slot is provided in a circular array on the top of the transfer processing cylinder, and a material turning assembly is arranged inside the transfer processing cylinder;

[0009] The material turning assembly includes an annular frame arranged inside the material trough and multiple sets of bevel gears arranged outside the transfer processing cylinder. The interior of the transfer processing cylinder is movably connected with a rotating shaft through a bearing, and the two ends of the rotating shaft are respectively fixedly connected to the annular frame and the bevel gear. The inner side of the annular frame is fixedly connected to a filter cloth.

[0010] Furthermore, the top of the transfer processing cylinder is provided with a limiting groove and a plurality of groups of slide grooves in a circular array, and two corresponding slide grooves are located on both sides of the limiting groove, and a limiting rotating block fixed to the rotating shaft located in the limiting groove is provided inside the limiting groove;

[0011] A limit slide rod is slidably connected in the slide groove, a cover plate is fixedly connected to the top of the limit slide rod, a guide ball is fixedly installed on the top of the cover plate through a short rod, and a pressure block for limiting the rotation of the limit rotating block is fixedly installed on the bottom of the cover plate.

[0012] Furthermore, two arc-shaped bevel gear plates meshing with bevel gears are fixedly mounted on the annular inner side wall of the main frame, a guide track is fixedly connected to the bottom of the upper cover shell, and the guide ball is slidably connected in the guide track.

[0013] Furthermore, a blowing mechanism for blowing air into the main frame is fixedly installed on the top of the upper cover shell, and a dust collecting box is installed on the lower cover shell through a through groove opened at its bottom. The top and bottom of the upper cover shell and the lower cover shell are respectively connected with an inlet pipe and an outlet pipe.

[0014] Furthermore, the top and bottom of the transfer treatment cylinder are fixedly installed with an outer sealing frame and an inner sealing frame, the top of the lower cover shell is fixedly installed with a basic frame connected to the dust collecting box and the outlet pipe, the outer sealing frame and the inner sealing frame at the top of the transfer treatment cylinder are slidably connected to the two corresponding annular grooves opened at the bottom of the upper cover shell, and the outer sealing frame and the inner sealing frame at the bottom of the transfer treatment cylinder are slidably connected to the two corresponding annular grooves opened at the top of the basic frame.

[0015] Furthermore, a motor for driving the transfer processing cylinder to rotate is fixedly installed on the top of the upper cover shell, and a sealing treatment is performed between the upper cover shell, the main frame and the lower cover shell.

[0016] Furthermore, annular sliding frames are provided on the annular inner side wall of the main frame and on both sides of the arc-shaped bevel gear plate in the vertical direction, and the outer side of the transfer treatment cylinder is movably connected to the inner side of the annular sliding frame by a bearing.

[0017] The present invention also proposes an operating method of a dry mortar dust removal device based on powder recovery, comprising the following steps:

[0018] Step 1: Filtration process: The motor drives the transfer treatment cylinder to rotate, the dust gas enters the material trough from the inlet pipe, the filter cloth intercepts the dust, and the purified gas is discharged through the base frame and the outlet pipe. Multiple groups of filter cloths realize continuous filtration.

[0019] Step 2: First flipping and dust cleaning: The guide ball slides along the guide track to the arch, pulls up the cover plate and the pressure block, loosens the limit rotating block, and the bevel gear engages with the arc-shaped bevel gear plate, driving the annular frame to flip 180 degrees. The dust on the filter cloth falls into the dust collecting box, and the blowing mechanism removes the residual dust. Then the guide ball falls back, and the pressure block presses the limit rotating block again.

[0020] Step 3: Reset and continue filtering: Guide the ball to another arched position, repeat the above action to make the annular frame flip and reset again, ready for continuous filtering of subsequent dust.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The beneficial effect of the present invention in terms of filtration continuity: by arranging a transfer treatment cylinder between the inlet and outlet pipes, a plurality of material troughs are provided in a circular array on the outside thereof, and a reversible circular frame and filter cloth are provided in the material trough. When a large amount of dust is attached to the surface of a filter cloth, the transfer treatment cylinder rotates and accurately causes the inlet pipe to be connected with the next filter cloth without dust attached, ensuring that the filtration of dusty gas can be carried out continuously and uninterruptedly, effectively overcoming the drawback of interrupting filtration due to cleaning in the prior art, being able to better meet the needs of continuous production and ensure the smoothness of the production process.

[0023] 2. The beneficial effects of the present invention in terms of cleaning convenience and automation: when a large amount of dust is attached to the surface of the filter cloth, the filter cloth with dust attached passes through a specific path twice along the guide track through the guide ball, realizes two 180-degree flips, and uses the strong wind force of the blowing mechanism to efficiently blow the dust on the surface of the filter cloth into the dust collecting box. The entire cleaning process does not require shutdown. The continuous cleaning and collection of dust on the surface of the filter cloth is completed while the equipment is running normally, which greatly improves the cleaning efficiency and ensures the continuous operation of the equipment, providing more convenient and efficient guarantees for production operations. That is, by realizing continuous filtration of dust gas and automatic continuous cleaning and collection of filter cloth dust, the overall efficiency of dry mortar production can be greatly improved.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1: Figure 1-Figure 13 As shown, the dry mortar dust removal equipment based on powder recovery includes a main box, which is composed of an upper cover shell 201, a main frame 202 and a lower cover shell 203. The installation direction of the present invention is Figure 1As shown, a blowing mechanism 10 for blowing air into the main frame 202 is fixedly installed on the top of the upper cover shell 201;

[0041] It should be explained here that the blowing mechanism 10 is an existing device, which is used to blow the filter cloth 703 in the material trough 8 to clean the dust on the surface of the filter cloth 703, so as to prevent a large amount of dust from clogging the surface of the filter cloth 703 and affecting the subsequent filtering function of the filter cloth 703;

[0042] The lower housing 203 is provided with a dust collecting box 19 through a through slot at the bottom thereof. The dust collecting box 19 is used to collect dust on the surface of the filter cloth 703. Figure 1 As shown, the bottom of the ash box 19 is also connected to a pipe for sucking the dust inside the ash box 19 into an external storage device. The top and bottom of the upper cover shell 201 and the lower cover shell 203 are respectively connected to an inlet pipe and an outlet pipe. The end of the inlet pipe away from the upper cover shell 201 is connected to a dust suction mechanism. The dust suction mechanism is a prior art. The inlet pipe uses the dust suction mechanism to collect the dust generated during the processing of the dry mortar into the main box, and the gas after the dust is filtered is discharged to the outside through the outlet pipe.

[0043] A transfer processing cylinder 9 is arranged inside the main frame 202, and a material trough 8 is provided in a circular array on the top of the transfer processing cylinder 9, and a material turning assembly is arranged inside the transfer processing cylinder 9;

[0044] The material turning assembly includes an annular frame 701 arranged inside the material trough 8 and multiple sets of bevel gears 702 arranged outside the transfer processing cylinder 9. Two arc-shaped bevel gear plates 13 meshing with the bevel gears 702 are fixedly installed on the annular inner wall of the main frame 202. The arc-shaped bevel gear plate 13, i.e., the top of the arc-shaped plate, is provided with bevel teeth meshing with the bevel gear 702. The installation position of the arc-shaped bevel gear plate 13 is as shown in FIG. Figure 7 As shown, and it needs to be further explained that the distance between the two arc-shaped bevel gear plates 13 is greater than the diameter of a single trough 8;

[0045] The interior of the transfer treatment cylinder 9 is movably connected with a rotating shaft through a bearing, and the two ends of the rotating shaft are respectively fixedly connected to the annular frame 701 and the bevel gear 702. The inner side of the annular frame 701 is fixedly connected with a filter cloth 703. The meshing transmission between the bevel gear 702 and the arc-shaped bevel gear plate 13 drives the rotating shaft to rotate, and further drives the annular frame 701 to flip 180 degrees and flip and reset 180 degrees.

[0046] The top of the transfer treatment cylinder 9 is provided with a limiting groove 6 and a plurality of groups of slide grooves in a circular array, and two corresponding slide grooves are located on both sides of the limiting groove 6. A limiting rotating block 704 fixed to the rotating shaft located in the limiting groove 6 is provided inside the limiting groove 6. A limiting sliding rod is slidably connected in the slide groove, and a cover plate 5 is fixedly connected to the top of the limiting sliding rod.

[0047] A guide ball 4 is fixedly installed on the top of the cover plate 5 through a short rod, and a pressure block 3 for limiting the rotation of the limit rotating block 704 is fixedly installed on the bottom of the cover plate 5. The bottom of the upper cover shell 201 is fixedly connected to a guide rail 14, and a guide rail groove is opened at the bottom of the guide rail 14. The guide ball 4 is slidably connected in the guide rail 14.

[0048] A motor for driving the transfer treatment cylinder 9 to rotate is fixedly mounted on the top of the upper cover shell 201 .

[0049] The guide rail 14 is as follows Figure 11-13 As shown, the positions corresponding to the guide rail 14 and the arc-shaped bevel gear plate 13 are both vertically arched. In specific applications, the motor drives the transfer treatment cylinder 9 to rotate, and at the same time, the dust gas enters the material trough 8 in the transfer treatment cylinder 9 through the inlet pipe, and the dust is blocked on the top of the filter cloth 703. The filtered gas is discharged to the outside through the base frame 17 and the outlet pipe in turn;

[0050] The filter cloth 703 in the material trough 8 arranged in a circular array on the surface of the transfer treatment cylinder 9 continuously filters the dust gas in the inlet pipe, and the guide ball 4 slides in the guide track 14. When the guide ball 4 passes through the arch of the guide track 14, it drives the cover plate 5 and the pressure block 3 to rise synchronously until the pressure block 3 releases the tightness against the limit rotating block 704, and then the corresponding bevel gear 702 meshes with the arc-shaped bevel gear plate 13 and drives the rotating shaft and the annular frame 701 to flip 180 degrees. At this time, the guide ball 4 drops from the arch of the guide track 14 to the low position, and the pressure block 3 re-tightens the limit rotating block 704 to prevent the annular frame 701 from spinning under the strong wind force of the blowing mechanism 10;

[0051] When the annular frame 701 turns 180 degrees, the dust originally attached to the top of the filter cloth 703 rotates 180 degrees synchronously and falls accurately into the dust collecting box 19 through the base frame 17, and the dust on the surface of the filter cloth 703 is completely removed under the strong wind force of the blowing mechanism 10;

[0052] When the dust on the surface of the filter cloth 703 is cleaned, the guide ball 4 passes through another arched part of the guide track 14, and drives the cover plate 5 and the pressure block 3 to rise synchronously again until the pressure block 3 releases the tightness against the limit rotating block 704, and then the corresponding bevel gear 702 meshes with the arc-shaped bevel gear plate 13 and drives the rotating shaft and the annular frame 701 to flip 180 degrees, and the guide ball 4 drops from the arched part of the guide track 14 to the low position, and the pressure block 3 re-tightens the limit rotating block 704 to continuously filter the dust entering the pipeline.

[0053] Embodiment 2: In this embodiment, an outer sealing frame 15 and an inner sealing frame 16 are fixedly installed at the top and bottom of the transfer treatment cylinder 9, and a base frame 17 connected to the ash collecting box 19 and the outlet pipe is fixedly installed on the top of the lower cover shell 203. The outer sealing frame 15 and the inner sealing frame 16 at the top of the transfer treatment cylinder 9 are slidably connected to the two corresponding annular grooves opened at the bottom of the upper cover shell 201;

[0054] The outer sealing frame 15 and the inner sealing frame 16 at the bottom of the transfer treatment cylinder 9 are slidably connected with the two corresponding annular grooves opened at the top of the base frame 17. The outer sealing frame 15 and the inner sealing frame 16 are arranged above and below the transfer treatment cylinder 9, so that the transfer treatment cylinder 9 can ensure good sealing during the rotation process, and the upper cover shell 201, the main frame 202 and the lower cover shell 203 are sealed.

[0055] Annular slide frames 18 are provided on the annular inner wall of the main frame 202 and on both vertical sides of the arc-shaped bevel gear plate 13. The annular slide frames 18 are used to stably support the mechanical energy of the transfer processing cylinder 9 to ensure its normal operation. The outer side of the transfer processing cylinder 9 is movably connected to the inner side of the annular slide frame 18 by a bearing.
