Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of environmental protection equipment, and specifically relates to a bin top dust collector. BACKGROUND

[0002] Dust raising phenomenon often occurs when materials are added in the bin, the bin top dust collector is arranged on the bin top, dust is collected and filtered to avoid pollution to the environment caused by emission into the atmosphere. The bin top dust collector is usually equipped with a pulse backflushing assembly to remove dust on the filter cloth to prevent the filter cloth from being blocked. However, due to non-stop operation, the removed dust is quickly sucked back to the filter cloth, resulting in low equipment efficiency. SUMMARY

[0003] To solve the problem of low equipment efficiency in the prior art, the utility model provides a bin top dust collector.

[0004] The utility model employs the technical scheme that a bin top dust collector comprises a box body, a mounting plate and filter bags.

[0005] An air outlet is arranged on the box body, the mounting plate is arranged in the box body, a plurality of filter bags are arranged on the mounting plate, the plurality of filter bags are divided into at least two groups, adjacent two groups of filter bags are separated by a partition plate, and the partition plate is arranged on the mounting plate; an air bag is further arranged outside the box body, the air bag is connected with at least two groups of inflation pipes, each group of inflation pipes is arranged above a corresponding group of filter bags and used for blowing air to the filter bags; and at least two groups of covers are further arranged on the top of the box body, the covers are connected with a lifting mechanism, and each group of covers is arranged directly above a corresponding group of filter bags.

[0006] In some embodiments, the bottom of the partition plate is lower than the bottom of the filter bag.

[0007] In some embodiments, the cover comprises a cover plate and a baffle, the baffle is arranged at the bottom edge of the cover plate, and the baffle is provided with a gap to avoid the inflation pipe.

[0008] In some embodiments, the air bag is connected with at least two gas collecting pipes, each gas collecting pipe corresponds to a group of inflation pipes, and an electromagnetic valve is arranged between the gas collecting pipe and the air bag.

[0009] In some embodiments, the gas collecting pipe is arranged outside the box body and close to a corresponding group of filter bags.

[0010] In some embodiments, a support is further arranged outside the box body, and the air bag is arranged on the support.

[0011] In some embodiments, the lifting mechanism is a pneumatic cylinder, the pneumatic cylinder is arranged on the top of the box body, and the output end of the pneumatic cylinder is connected with the cover.

[0012] In some embodiments, a fan is provided outside the air outlet.

[0013] The beneficial effects of this utility model are as follows: In this solution, a partition is used to separate two adjacent sets of filter bags. When one set of filter bags is clogged, the corresponding cover is lowered to cover the corresponding set of filter bags. Then, air is blown onto the corresponding filter bags using an air bag to remove the dust on the filter bags. At this time, due to the effect of the cover, the airflow to that set of filter bags is greatly reduced, and the removed dust can settle and will not be sucked back. At the same time, due to the effect of the partition, the removed dust will not be immediately adsorbed by the adjacent set of filter bags, thus achieving efficient dust removal from the filter bags without stopping the machine, avoiding filter bag clogging, and thereby improving the efficiency of the equipment.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but it is not limited thereto. Any improvements or substitutions on the basic spirit of the embodiments of the present invention shall still fall within the scope of protection of the present invention.

[0017] like Figure 1 As shown, the dust collector used in this scheme includes a housing 1, a mounting plate 2, and filter bags 3;

[0018] The housing 1 is provided with an air outlet 11. The mounting plate 2 is installed inside the housing 1. Multiple filter bags 3 are installed on the mounting plate 2. The multiple filter bags 3 are divided into at least two groups. Adjacent groups of filter bags 3 are separated by partitions 4, which are installed on the mounting plate 2. An air tank 5 is also provided outside the housing 1. The air tank 5 is connected to at least two sets of inflation pipes 6. Each set of inflation pipes 6 is installed above the corresponding group of filter bags 3 for blowing air onto the filter bags 3. At least two sets of covers 8 are also provided on the top of the housing 1. The covers 8 are connected to a lifting mechanism 9. Each set of covers 8 is positioned directly above the corresponding group of filter bags 3.

[0019] When the silo top dust collector works, the dust in the silo moves towards the silo top dust collector with the airflow from the inside of the silo body, the dust is intercepted and filtered by the filter bag 3, and the purified gas is discharged to the atmosphere or subsequent processing equipment through the gas outlet 11. When one group of filter bags 3 adsorbs more dust, the corresponding cover 8 is lowered under the drive of the lifting mechanism 9, covers the corresponding group of filter bags 3, the gas pocket 5 introduces high-pressure gas into the corresponding group of inflation pipes 6, the inflation pipes 6 spray high-pressure gas into the filter bags 3 for back blowing to blow off the dust adsorbed on the filter bags 3, due to the effect of the cover 8, the airflow in the silo body towards the group of filter bags 3 is greatly reduced, and the blown-off dust can be fully settled, and due to the effect of the partition plate 4, the blown-off dust will not be immediately adsorbed by the adjacent group of filter bags 3. After the blown-off dust settles, the lifting mechanism 9 drives the cover 8 to rise and reset, and the group of filter bags 3 normally performs the filtering work. The at least two groups of filter bags 3, inflation pipes 6 and covers 8 alternately and repeatedly perform the above operation, effectively avoiding the blown-off dust being sucked back to the filter bags 3, and improving the dust removal efficiency of the silo top dust collector.

[0020] In order to avoid the mutual influence between the two adjacent groups of filter bags 3, in some embodiments, the bottom of the partition plate 4 is lower than the bottom of the filter bag 3. The partition plate 4 extends to the bottom of the filter bag 3, so that the blown-off dust is less likely to be immediately adsorbed by the adjacent group of filter bags 3, and the settlement effect of the blown-off dust is ensured.

[0021] As an optimization of the above-mentioned embodiments, in some embodiments, the cover 8 includes a cover plate 81 and a baffle 82, the baffle 82 is arranged at the bottom edge of the cover plate 81, and the baffle 82 is provided with a avoiding gap for avoiding the inflation pipe 6. The cover 8 formed by the cover plate 81 and the baffle 82 can cover the corresponding group of filter bags 3 to form a relatively closed space, not only greatly reducing the airflow on one side of the corresponding group of filter bags 3, but also facilitating the back blowing effect of the inflation pipe 6 on the filter bag 3, and the avoiding gap avoids the interference between the cover 8 and the inflation pipe 6.

[0022] Specifically, in some embodiments, the gas pocket 5 is connected with at least two gas collecting pipes 7, each gas collecting pipe 7 corresponds to a group of inflation pipes 6, and an electromagnetic valve 51 is arranged between the gas collecting pipe 7 and the gas pocket 5. The gas collecting pipe 7 can be connected with multiple inflation pipes 6, thereby corresponding to multiple filter bags 3 in a group of filter bags 3, and the electromagnetic valve 51 can independently control the on-off of the gas collecting pipe 7 and the gas pocket 5, thereby realizing the independent control of the back blowing of each group of filter bags 3.

[0023] Further, the gas collecting pipe 7 is arranged outside the box body 1 and close to the corresponding group of filter bags 3. Arranging the gas collecting pipe 7 close to the corresponding group of filter bags 3 can reasonably arrange the inflation pipes 6, so that the inflation pipes 6 correspond to the corresponding group of filter bags 3, and the arrangement of the inflation pipes 6 is more reasonable.

[0024] In order to facilitate the installation of the air pocket 5, in some embodiments, the box 1 is further provided with a bracket 12 outside, and the air pocket 5 is installed on the bracket 12.

[0025] As a preferred, in some embodiments, the lifting mechanism 9 is a pneumatic cylinder, which is installed on the top of the box 1, and the output end is connected with the cover 8. The pneumatic cylinder has simple structure, is easy to control, and can flexibly control the lifting of the cover 8.

[0026] In order to improve the air volume of the air outlet 11, in some embodiments, the air outlet 11 is provided with a fan outside. The fan can accelerate the air flow in the warehouse top dust collector to be introduced out, and then improve the filtering efficiency.

[0027] The above specific embodiments further illustrate the purpose, technical scheme and beneficial effects of the utility model, and it should be understood that the above description is only for specific embodiments of the utility model, and is not used to limit the utility model. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
