Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction systems, in particular to a spray dust reduction system in a recycling resource processing workshop. Background Art

[0002] The workshop is the basic unit for organizing production within an enterprise and is also the first-level organization for production administration. It consists of several work sections or production teams. It is set up according to the professional nature of each stage of product production or each component of the product and the professional nature of each auxiliary production activity within the enterprise. It has the necessary factory buildings or sites, machinery and equipment, tools and a certain number of production personnel, technicians and managers to complete the production tasks.

[0003] A workshop has four characteristics: (1) It is a gathering place for various factors of production formed according to the principle of specialization.

[0004] (2) It is the intermediate link in enterprise management between the factory and the production team.

[0005] (3) The products of a workshop are generally semi-finished products (except for finished product workshops) rather than commercial products.

[0006] (4) A workshop is not an independent commodity production and operation unit and generally does not have direct economic relations with the outside world.

[0007] The recycling processing workshop is used to collect recyclable materials from waste items (such as scrap steel from various products), and usually goes through processes such as removing impurities, crushing, packaging and briquetting, and stacking to produce recycled resource material blocks that can be reused as production raw materials.

[0008] Since waste materials come from different sources, they often contain a lot of impurities, especially during the transportation and crushing process, a lot of dust particles will be raised. Dust can cause great harm to employees' health and can cause pneumoconiosis. In addition, dust can also cause rhinitis, pharyngitis, folliculitis, pyoderma, keratitis and other diseases; toxic dust or radioactive dust may also cause occupational poisoning or respiratory tumors. In addition, dusty workplaces reduce visibility, affect the vision of operators, hinder workers' operations, and thus affect product quality, and even cause accidents. Therefore, dust reduction equipment is needed to deal with dust.

[0009] The commonly used dust reduction equipment on the market is described in the document with patent number CN202123128671.0 and name “A dust prevention device for a medium crushing workshop of sand and gravel aggregates”, which includes a spray dust reduction mechanism arranged in the medium crushing workshop, a discharging conveyor belt arranged at the outlet of the medium crushing workshop, and a dust cover arranged above the discharging conveyor belt.

[0010] Although the above-mentioned spray dust reduction equipment can be used to reduce dust at the locations where dust is generated in the production workshop, due to the large opening of the door of the recycling processing workshop, it is impossible to prevent dust from drifting from the door of the workshop to the outside and causing pollution. In addition, due to the large area of ​​the workshop, spray dust reduction requires filtering and consumes a large amount of clean water, which has high operating costs and is not conducive to the company's control of production costs.

[0031] In order to solve the problem that general workshop spray dust reduction equipment on the market can only perform spray dust reduction treatment on the workstations where dust is generated in the workshop, but cannot prevent dust from drifting from the workshop gate to the outside and causing pollution, and has large water consumption and high operating costs, we provide a spray dust reduction system for renewable resource processing workshops.

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figures 1 to 3 As shown, the present embodiment provides a spray dust suppression system for a recycling resource processing workshop, including a processing workshop 1, wherein the processing workshop 1 is provided with an entrance and exit gate 101, and a spray system 2 is provided in the processing workshop 1, wherein the spray system 2 includes a water storage container 201, a water purification module 202, and a booster pump 203 which are sequentially connected by pipelines, and the output end pipeline of the booster pump 203 is connected with a plurality of atomizing nozzles 204, and the atomizing nozzles 204 are evenly arranged vertically downward and installed on the inner top of the processing workshop 1, and the water purification module 202 is also connected with a water curtain module 3 by pipeline, and the water curtain module 3 is installed on the outer top of the entrance and exit gate 101.

[0036] Among them, the atomizing nozzle 204 can generate a large amount of fine water mist, effectively absorb dust in the air and reduce water consumption, saving the operating cost of the equipment. In addition, the fine water mist will not wet the floor of the workshop, which can avoid the impact of spraying dust on the operation of the workshop. The water curtain module 3 can produce a water curtain at the entrance and exit gate 101, and use the water curtain to absorb dust near the entrance and exit gate 101 to prevent dust from drifting to the outside and causing pollution.

[0037] The booster water pump 203 is connected to a high-pressure water pipe 4, and the lower part of the high-pressure water is connected to a plurality of atomizing nozzles 204 through a three-way joint 401. The design of the atomizing nozzles 204 directly connected to the water delivery pipeline through a three-way joint is simple and direct, which can effectively save equipment costs.

[0038] A plurality of steel ropes 5 are arranged on the inner top of the processing workshop 1, and the high-pressure water pipe 4 is connected to the lower part of the steel rope 5 through a clamp 6. The steel rope 5 cooperates with the clamp 6 to quickly stretch the high-pressure water pipe 4 equipped with the atomizing nozzle 204 and fix it on the inner top of the processing workshop 1, effectively reducing the difficulty of installing the spray system 2.

[0039] The water curtain module 3 includes an upper water pump 301, a top water tank 302, a high-pressure water pump 303 and a nozzle module 304 which are connected in sequence by pipelines. A plurality of nozzle modules 304 are equidistantly arranged and installed on a nozzle bracket 7, and the nozzle bracket 7 is installed on the top outer side of the entrance and exit gate 101. The water supply mechanism of the water curtain module 3 is independent of the spray system 2, so as to avoid the spray system 2 and the water curtain module 3 being always turned on at the same time, resulting in water waste.

[0040] The length of the nozzle bracket 7 is greater than the width of the entrance and exit door 101, and the spray direction of the nozzle module 304 is downward and inclined toward the outside of the entrance and exit door 101. The width of the water curtain generated by the water curtain module 3 is wider than the entrance and exit door 101 and wraps the door, which can effectively use water mist to absorb dust and settle it, preventing dust from escaping to the outside.

[0041] The high-pressure water pump 303 is connected to a plurality of nozzle modules 304 through a water distributor 8, and the nozzle modules 304 include rotating nozzles. The water distributor 8 can ensure that the water volume of each nozzle module 304 is uniform, and the rotating nozzle can adopt a rotating nozzle product on the market, so as to improve the coverage of a single nozzle and save the usage of the nozzle modules 304.

[0042] The booster pump 203 is electrically connected to the industrial control module 9, and the industrial control module 9 is electrically connected to the timer 10, and the timer 10 is set on the inner ground of the processing workshop 1. The industrial control module 9 cooperates with the timer 10 to enable the booster pump 203 to start at regular intervals, so as to spray at regular intervals and further save water. In this embodiment, the timer 10 is installed on the operating table 11 in the workshop, which is convenient for the staff to set as needed.

[0043] It is worth mentioning that the industrial control module 9 (Siemens IPC477E) and the timer 10 (Manken KG315T) can both be commercially available products, so their operating principles will not be described in detail here.

[0044] A dust sensor 12 is provided on the inner side of the entrance and exit gate 101, and the industrial control module 9 is electrically connected to the dust sensor 12 and the water curtain module 3. The dust sensor 12 (Sifang Optoelectronics PM1009) can also use a product on the market. When dust is detected approaching the gate, the industrial control module 9 starts the high-pressure water pump 303 of the water curtain module 3 to generate a spray water curtain, thereby avoiding the water curtain module 3 running for a long time and causing water waste.

[0045] The input end of the water storage container 201 is connected to the water pipe 14 through the solenoid valve 13. The inner bottom and top of the water storage container 201 are both provided with liquid level sensors 15. The solenoid valve 13 and the liquid level sensor 15 are electrically connected to the industrial control module 9. The water pipe 14 can be a tap water pipe, a grey water pipeline or a recycled water source processed within the enterprise. When the liquid level sensor 15 detects that the water volume in the water storage container 201 is insufficient, the industrial control module 9 automatically controls the solenoid valve 13 to open and inject water into the water storage container 201, and closes the solenoid valve 13 after the water level reaches the liquid level sensor 15 at the top. Since the equipment for automatic water injection by the liquid level meter linked to the solenoid valve has also been used in this field for a long time, those skilled in the art can directly use the products on the market to achieve the technical effect, so the operating principle thereof will not be described here.

[0046] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
