Description

  The present invention relates to a distributed dust collection system characterized in that a dust collection operation is performed by connecting a plurality of dust collectors by a suction pipe communicating with one suction device.

  In many factory production lines, there are cases where it is necessary to clean up or improve the working environment mainly for environmental improvement, and it covers various industries. For example, in a factory that handles powders, there is a problem that countermeasures against dust contamination are always around, and in particular, in a factory that produces food, there is a requirement that foreign matters must be avoided from entering the product. In order to satisfy these requirements, the object of cleaning and cleaning covers the entire manufacturing equipment and its surroundings, from the floor to the ceiling, and in addition to regular cleaning, maintain a system that can be cleaned or cleaned as needed. I have to keep it. The types of foreign matter collected are not limited to so-called trash, but range widely from solids, liquids, and gases, such as water and other liquids, and fine dust that is difficult to grasp with normal attention.

  In the conventional dust collection technology, a large dust collector is installed outside the factory building, the branch pipe is branched through a duct pipe connected to the large dust collector, and a suction part such as a nozzle is provided at the end of the branch pipe network. It is normal to take a configuration of providing In such a system, the foreign matter sucked from the nozzle at the end is sucked by the large suction air volume of the large dust collector, passes through the branch pipe, and is collected by the large dust collector. Therefore, the suction airflow passes through the pipe from the end nozzle and accumulates in the large dust collector while containing foreign matter, and adheres to the inner wall of the pipe by continuing long-term use, and also accumulates at the corners etc. Sometimes it happens. These situations reduce suction performance and require periodic cleaning of the system.

  One of the problems with the conventional system is that it appears prominently when the aspirated material is a powdered raw material for medicines and foods, but it creates a cause for the growth of fungi and germs, causing pests such as flies and rats, It means that there is a big problem in health and safety because it will attract pests. Another problem is that when there are many types of foreign matter sucked at each suction point, all kinds of foreign matters are mixed inside the large dust collector, and therefore, separate collection is impossible. Since the dust collection technology is also applied to, for example, collecting dust scattered when subdividing the raw material powder into containers (Japanese Patent Laid-Open No. 2005-112373), a specific substance such as this raw material powder is recovered and recycled. There is a possibility that it will be used, but it cannot be reused or recycled in a conventional system that eventually mixes with other collected matter inside the dust collector.

  Another problem is that cleaning and inspection can be performed only when all systems are stopped. Since all operations that require the suction of foreign matter in the factory must be stopped and cleaning must be performed, the factory production line is effectively stopped, which has a significant impact and lowers production efficiency. It also affects the product cost. In addition, in conventional systems, it is necessary to select whether to suck dry dust (dry type) or hot / smoke or liquid mist (wet type), and perform dry and wet suction simultaneously at multiple locations. I can't do it. In addition, in the technique related to the collection of foreign matter, it is not possible to find a thing that contributes to the solution of the above problems.

JP-A-2005-112373

  The present invention has been made by paying attention to the above points, and an object of the present invention is to provide a distributed dust collection system improved in a direction in which foreign matter does not remain inside the pipe. Another object of the present invention is to provide a distributed dust collection system that can separate and collect foreign substances and can perform maintenance for each individual dust collector. Another object of the present invention is to provide a distributed dust collection system that can simultaneously perform dry and wet suction at a plurality of locations.

In order to solve the above problems, the present invention provides:
One suction device and main piping leading to the suction device;
A plurality of pipe branches provided in the main pipe,
A plurality of suction pipes having a connection part connected to each pipe branch part at one end and connected to the dust collector at the other end,
The above dust collector having a suction port and an exhaust port, and having a built-in separation means for capturing and separating foreign matter contained in the air flow sucked from the suction port, and discharging the air flow from the exhaust port to the suction pipe ,
A suction part connected to the suction port at the base end part and provided with a suction nozzle at the tip part;
An intake control unit for connecting the suction device and the dust collector to a state capable of suction;
Means is provided for configuring a dust collector that leads to an arbitrary suction pipe by operation of the intake control unit.

  In the present invention, the foreign matter is collected by a dust collector, but the “foreign matter” in the present invention is collected with waste, sewage, etc., for example, dust that scatters when subdividing the raw material powder into containers. It is a concept that includes an object to be sucked for reuse. That is, the concept that is the closest to the foreign object in the present invention is the air flow subtracted from the air flow sucked by the dust collector. The types of foreign substances include a wide range from solids and liquids to those close to gases, such as so-called solid waste, sewage, waste liquid, and other liquids, and fine dust that is difficult to grasp with normal attention.

  Therefore, the “dust collector” in the present invention does not collect only dust, and can collect all objects close to solids, liquids, and gases. As such a dust collector, it is recommended to use a dual-purpose dust collector capable of sucking both solid and liquid foreign matters in the present invention. However, it goes without saying that a solid suction machine or a liquid suction machine can also be used. It would be more desirable if a dust collector having a further improved structure for cleaning could be used as the dust collector. By cleaning the dust collector and keeping its suction function in the best state, the flow of the piping downstream of the cleaner becomes a cleaner airflow, and the best effect can be obtained.

  The distributed dust collection system of the present invention is provided with a main pipe leading to one suction device, a plurality of pipe branch portions provided in the main pipe, a plurality of suction pipes, the dust collector, and a suction nozzle at the tip. A suction unit and an intake control unit are required. In short, the present invention is characterized in that a plurality of dust collectors are provided for one suction device, and foreign matters are individually collected in each dust collector and are not allowed to flow downstream. Compared with the conventional system, it can be said that the conventional system is a centralized dust collection system that collects and collects foreign matter with a single large dust collector, whereas the system of the present invention is configured so that the foreign matter is individually collected for each dust collector. It can be said that it is an individual dust collection system that collects in

  The suction device functions as a suction force source that provides a suction force necessary for suctioning foreign matter by a plurality of dust collectors. A plurality of pipe branches are provided in the main pipe that leads to the suction device. The pipe branching portion is a part for branching a plurality of suction pipes from the main pipe, and a structure in which the suction pipe is fixedly attached to the main pipe and a structure in which the suction pipe is detachably attached can be selected. In the case of adopting a structure in which the suction pipe is detachably attached, a suction outlet is equipped. The suction outlet is the end of the main pipe, and is a connection of the suction pipe that leads to each dust collector. For example, in the case where the present invention is assumed to be implemented in a factory, the above-described suction outlet can be installed and used at a site near a wall or near each shop in the same manner as a so-called outlet for power distribution.

  The suction pipe is fixedly connected to each pipe branching section, or is detachably provided at the connection section connected to the suction outlet, and the other end is connected to the dust collector, It is a means for communicating between the fixed equipment up to the main pipe and the dust collector, which is equipment that can select any number of units. The suction pipe portion is suitable as a part where an intake control section described later is provided together with the pipe branching section.

  The above dust collector has a suction port and an exhaust port, and has a built-in separation means for capturing foreign matter contained in the air flow sucked from the suction port and separating it from the air flow. To be discharged. As the built-in separation means, there are a means for separating liquid and a means for separating dust, and it is most desirable that it is a dust collector equipped with both separation means in one unit, and a solid and liquid dedicated machine can also be used. As mentioned above, a dust collector that can be washed is more desirable.

  The suction part is connected to the suction port of the dust collector at the base end part, and is provided with a suction nozzle at the end part, and is located at the most end in the system of the present invention. In order to suitably suck a solid, liquid, or gas-like thing, the suction portion is provided with a solid suction nozzle, a liquid suction nozzle, and a fine dust suction nozzle. However, for example, since it is possible to suck the liquid using a solid suction nozzle, more efficient suction can be performed using the liquid nozzle.

  In order to connect the suction device and the dust collector to a suckable state, the above-described intake control unit is provided. The intake control unit is for operating a dust collector that leads to an arbitrary suction pipe by its operation.For example, it is desired to have a function of an on-off valve and a flow control valve, and a suction pipe that leads to an unused dust collector is provided. In addition to closing, the suction pipe leading to the dust collector to be used is opened and the degree of valve opening is adjusted. As the intake control unit, an air volume adjusting damper can be provided in each suction pipe.

  Since the present invention is configured and operates as described above, a distributed dust collection system improved in a direction in which foreign matter does not remain inside the pipe is provided by separating and collecting the sucked foreign matter with a dust collector. be able to. In addition, according to the present invention, it is possible to provide a distributed dust collection system that can separate and collect foreign matters for each of a plurality of dust collectors, and can perform maintenance for each individual dust collector. it can. Further, according to the present invention, it is possible to simultaneously perform dry and wet suction using a plurality of dust collectors.

  Hereinafter, the distributed dust collection system according to the present invention will be described in more detail with reference to the illustrated embodiment. FIG. 1 is an explanatory diagram conceptually showing a distributed dust collection system 10 according to the present invention, in which 11 is a suction device in one place, 12 is a main pipe, 13-1, 13- 2, 13-3,... Indicate suction outlets as a plurality of piping branch portions. 14-1, 14-2, 14-3... Are a plurality of suction pipes, each having a connection portion 15 as a connection means with each suction outlet 13-1. A connecting portion 16 connected to the dust collectors 17-1, 17-2, 17-3,.

  The suction device 11 includes, for example, a large air volume suction fan. As a matter of course, the suction device 11 must exhibit a suction force having a capacity suitable for the scale of the dust collection system for carrying out the present invention. The number of parts can be selected from methods such as one, two or more, or a case of selecting an arbitrary number of a plurality of units. The suction outlet 13 is installed at a site such as a wall in a factory, and is used in the same way as a distribution outlet so-called outlet. For connecting to the outlet like a plug in an electric device A connecting portion 15 is provided.

  In the illustrated example, 18-1, 18-2, 18-3 are intake control units, and in the illustrated example, are composed of air volume adjusting dampers arranged in the suction pipes 14. The air intake control section 18 comprising air volume adjusting dampers plays a role of a device for determining whether or not to operate each dust collector 17 in the example of the present embodiment, and is close to the dust collectors 17. Be placed. The connecting portion 16 on the other end side is also connected in the same manner as the coupling by the plug and the socket, and connects the suction pipes 14... And the dust collectors 17.

  The dust collector 17 is a solid suction and liquid suction combined machine, and is shown as using a suction nozzle for solid 37-1, a suction nozzle for liquid 37-2, and a suction nozzle for fine dust 37-3 as the suction part 35. (See FIG. 1). The dust collector 17 illustrated in the present embodiment has the configuration illustrated in detail in FIGS. 2 to 3, and includes an exhaust port 19 provided at the downstream end of the cylindrical dust collector main body 20, and a cylinder interior. It has a suction port 21 provided on the outer surface so as to suck the airflow from the tangential direction, and has separation means 22 for capturing and separating foreign matter flowing along with the airflow sucked from the suction port 21 inside.

  The separation means 22 is provided with a cone portion 23 formed in a downward cone and a cyclone separation for a cyclone method for separating foreign matter in the process of sucking, swirling, and stalling an air flow from the tangential direction inside the cylinder. A filter unit 24 is provided downstream of the cone unit 23 (upper part in the dust collector main body 20) in order to separate foreign matter in the process of passing the airflow that has passed through the means. The lower end of the cone part 23 is an opening 23a for container connection, and foreign matter separated by the cyclone method falls from here and is collected in the dust collecting containers 25-1, 25-2, 25-3. become. As a means for attaching / detaching the dust collecting containers 25..., A container attaching / detaching handle 25 a is provided on the container side, and a handle shaft engaging groove 23 b is provided on the opening side.

  The filter unit 24 is made of a so-called plastic filter that can be cleaned, and is detachably supported on the rim by a suspended structure so as to be taken in and out of the upper opening 26 of the dust collector body 20. The illustrated dust collector main body 20 is rotatably attached to a frame portion 27 having a size that allows the dust collector main body 20 to be disposed therein. A substantially U-shaped bearing portion 28 is installed in the frame portion 27, and a pivot 29 that is pivotally supported by the bearing portion 28 is provided at an intermediate portion on the outer surface of the dust collector main body 20, and the dust collector main body 20 is rotated by the rotation of the shaft support portion. The filter unit 22 is pulled out, and the entire main body, the inside of the main body, and the filter unit 22 can be cleaned. The dust collector main body 20 itself can be removed from the frame portion 27.

  A backwash mechanism 30 is disposed at the upper end of the frame portion 27. The backwashing mechanism 30 is means for periodically injecting an air jet onto the filter unit 24 from the direction opposite to the direction of the suctioned airflow when the suction airflow is stopped, and periodically cleaning the foreign matter adhering to the filter unit 24. The backwashing mechanism 30 is rotatably attached to the rear upper end of the frame portion 27 by a support shaft 31, thereby avoiding a conflict with the upper opening 26 when the dust collector main body 20 is inclined. 2 and 3, reference numerals 32 and 33 denote damper-equipped support arms. The support arm 32 supports the dust collector main body 20 on the frame 27 and defines the maximum inclination limit of the dust collector main body 20. The backwash mechanism 30 is supported when rotating upward. A caster 34 is provided for moving the frame portion 27.

  A suction part 35 is connected to the dust collector 17. The suction part 35 includes a hose 36 connected to the suction port 21 of the dust collector at the base end part, and a suction nozzle at the tip thereof, and is located at the most end of the system of the present invention. In order to suitably suck foreign matter including solid, liquid, and gas-like foreign matter, the suction unit 35 includes a solid suction nozzle 37-1, a liquid suction nozzle 37-2, and a fine dust suction nozzle 37-3. ing. The hose connected to the suction unit 35 may have a branch pipe, and a plurality of types of nozzles may be connected to the same suction port 21.

  Next, a distributed dust collection system according to the present invention configured as described above will be described. In the system 10 of the present invention, the suction device 11 is started and the intake control unit 18 is operated so that the dust collectors 17-1, 17-2, and 17-3 can be used. Needless to say, the connection portions 15 and 16 should be connected at this time. For the purpose of sucking an arbitrary foreign matter, for example, a solid foreign matter, the suction operation using the solid suction nozzle 37-1 becomes possible by opening the intake control unit 18-1. In addition, when using the solid suction and liquid suction combined machines 17-1, 17-2, and 17-3 as dedicated machines, respectively, as in the illustrated example, it is not necessary to use the above combined machine as a dust collector. It is clear that it is good.

  In the above case, the solid foreign matter is sucked from the solid suction nozzle 18-1, is subjected to the separation action from the air flow mainly by the cyclone method in the dust collector 17-1, is collected in contact with the cone portion 23, and falls. The dust is collected in the dust collecting container 25-1. Similarly, in the suction operation using the liquid suction nozzle 37-2, the liquid foreign matter is mainly separated from the air flow by the cyclone method, and the liquid foreign matter is collected in contact with the cone portion 23, falls, and is collected. -2. In addition, foreign matter sucked from the fine dust suction nozzle 37-3 is mainly subjected to a separation action by the cyclone method for those having a large mass or particle diameter, and is collected in the dust collecting container 25-3. The smaller fine dust is removed when the airflow passes through the filter unit 24 and adheres to the outer surface of the filter unit 24. The adhering fine dust is used when the filter unit 24 is air-washed by the operation of the backwash mechanism 30. Then, it peels off from the outer surface of the filter and falls into the dust collecting container 25-3.

  As described above, in the system 10 of the present invention, foreign substances close to solids, liquids, and gases can be separated and accumulated in dedicated dust collecting containers. This is only during the period from the nozzle 37-1, the liquid suction nozzle 37-2, and the fine dust suction nozzle 37-3 to the dust collectors 17-1, 17-2, 17-3. Therefore, foreign matter does not flow into the suction pipes 14. Accordingly, since the airflow flowing through the suction pipes 14 is fairly clean, the necessity for cleaning the inside of the suction pipes is significantly reduced. Further, since the collected foreign matter is accumulated in each of the dust collection containers 25-1, 25-2, 25-3, the subsequent processing is easy, and the solids and the liquid are not mixed and collected. Can also be reused.

That is, according to the present invention,
・ Repaired foreign materials are automatically separated, minimizing disposal costs.
・ Dry and wet dust collection work is possible at multiple locations at the same time.
・ Proliferation of mold and other bacteria is suppressed, entry of pests and pests can be prevented, and hygiene can be improved.
・ Individual maintenance according to the type of foreign material is possible, and it is not necessary to stop the entire plant.
