Description

Technical Field

[0001] The present invention relates to a dust suction device for pipeline transportation of fine building materials in the field of fine building material transportation. Background Art

[0002] Fine building materials, also known as fine aggregates, are building materials opposite to coarse aggregates. Fine aggregates are aggregates with relatively small diameters, and aggregates with a particle size below 4.75 mm are called fine aggregates. Fine building materials are granular loose materials that play a role of skeleton or filling in concrete. Fine aggregates are hard, clean, and well-graded. The fineness modulus of artificial sand is within the range of 2.4 - 2.8, and the fineness modulus of natural sand is preferably within the range of 2.2 - 3.0. Therefore, they can better fill the gaps in concrete, making the structure of the concrete more compact after setting.

[0003] Currently, during the transportation of fine aggregates, due to the relatively small particle size of fine aggregates, a large amount of dust will be generated during the transportation process. Therefore, closed pipelines are used for long-distance transportation to reduce the dust generated during transportation. However, when the fine aggregates are transported from the pipeline outlet to the collection box, the fine aggregates will still come into contact with the outside world, and the dust they raise will disperse in the air, thus causing great harm to both the environment and the operator.

[0004] Therefore, in order to reduce the dust diffusion at the pipeline outlet of fine aggregates, a sealing device is generally installed at the pipeline outlet, or a vacuum cleaner is used to absorb the floating dust to reduce the dust hazard. However, the installation and disassembly of the sealing device are relatively troublesome, and the pipeline diameter and the size of the collection box need to be designed adaptively to improve the sealing performance, which consumes a lot of design man-hours and production costs. Vacuum cleaners generally require an external power supply and cannot be used in some construction sites without a fixed power supply, and it also increases the energy consumption. Summary of the Invention

[0005] An object of the present invention is to solve at least one of the technical problems existing in the prior art, and provide a dust suction device for pipeline transportation of fine building materials, which adopts an open structure without installing a sealing device and reduces the dependence on external energy.

The number of the rubber balls and the fiber balls is multiple and both are arranged in the elastic balloon;

[0009] Among them, after the dust suction spherical shell is impacted by building fine materials, it vibrates. The rubber ball and the fiber ball rub against each other to generate heat energy and static electricity. The elastic balloon expands when heated and can contact the inner wall of the dust suction spherical shell. The static electricity charges generated inside the elastic balloon can be transferred to the dust suction spherical shell to adsorb the building fine materials.

The inlet port diameter of the aggregate trough is larger than the outlet port diameter. The outlet end of the aggregate trough is connected to the discharge port, and the outlet end of the dust suction pipe is communicated with the inlet end of the aggregate trough.

[0018] According to an embodiment of the present invention, further, the number of the aggregate trough and the discharge port is at least two and they are arranged in one-to-one correspondence. The outlet end of the dust suction pipe is communicated with at least one of the aggregate troughs.

The rubber balls and fiber balls in the elastic balloon collide and rub against each other to generate heat and static electricity.

[0029] The embodiment of the present invention provides a dust suction device for transporting building fine materials through pipelines. Compared with the traditional methods of using a sealing device to prevent dust from escaping or using an electric dust suction device for dust suction, this dust suction device for transporting building fine materials through pipelines does not need to be adaptively designed according to the size of the building fine material conveying pipe or the collection box, and has higher versatility; moreover, it uses a mechanical structure for dust suction, reducing the dependence on external energy and reducing energy consumption. Specifically, this dust suction device for transporting building fine materials through pipelines suspends the dust suction spherical shell 230 in the dust suction pipe 210 through an elastic rope 220, and when the building fine materials pass through, it can cause repeated oscillations of the dust suction spherical shell 230. An elastic balloon 240 is arranged in the dust suction spherical shell 230, and a plurality of rubber balls 250 and a plurality of fiber balls 260 are arranged in the elastic balloon 240. When the dust suction spherical shell 230 oscillates, the rubber balls 250 and fiber balls 260 in the elastic balloon 240 collide and rub against each other, thereby generating heat and static electricity. The heat causes the elastic balloon 240 to expand and fully contact the inner wall of the dust suction spherical shell 230, and the static charges can also be transmitted to the dust suction spherical shell 230 through the elastic balloon 240, so that the dust suction spherical shell 230 adsorbs the dust in the dust suction pipe 210 through static electricity to achieve the dust suction effect.

[0030] Referring to Figure 1 , the dust suction device for transporting building fine materials through pipelines in the embodiment of the present invention includes a bracket 100 and a dust suction mechanism 200. Among them, the bracket 100 is the main structure of this dust suction device for transporting building fine materials through pipelines, and is used to support and protect the dust suction mechanism 200. The bracket 100 is in a frame shape, with a feeding port 110 provided at the top and a discharging port 120 provided at the bottom. After the building fine materials enter from the feeding port 110, they pass through the dust suction mechanism 200 and are discharged from the discharging port 120.

[0031] Furthermore, the middle of the bracket 100 is hollowed out to expose the dust suction mechanism 200, and the feeding part and the discharging part of the bracket 100 are supported by multiple pillars, so that the working state of the dust suction mechanism 200 can be easily observed, and when a leakage accident occurs in the dust suction mechanism 200, it can be repaired in time; and it can also reduce the weight of the dust suction device for transporting fine materials in the building pipeline, and facilitate transportation and transfer. Moreover, the dust suction mechanism 200 can also be connected to the bracket 100 in a detachable connection manner, so that it is easy to remove it later for separate maintenance or replacement.

[0032] Furthermore, the feed inlet 110 is trumpet-shaped, with the large end being the inlet and connected to the construction fine material transport pipe, and the small end being the outlet and connected to the dust suction pipe 210 in the dust suction mechanism 200 (refer to Figure 2 ) docking, used to guide the building fine materials into the dust collection mechanism 200.

[0033] Furthermore, the bracket 100 further includes a collection trough 130, which is also trumpet-shaped, with a large end as an inlet and docked with the dust suction pipe 210, and a small end as an outlet and connected to the discharge port 120, so as to guide the discharge of the building fine materials in the dust suction pipe 210. Specifically, the number of the collection troughs 130 and the discharge port 120 is at least two and they are arranged one by one. The outlet end of the dust suction pipe 210 can be connected to at least one of the collection troughs 130. The specific connection method can be direct connection or indirect connection through a soft pipe, so as to realize the delivery of building fine materials to two or more collection boxes. The building fine material pipeline transportation dust suction device acts as a central control component of the transportation to control the output direction of the building fine materials.

[0034] Reference Figures 2 to 3, the dust suction mechanism 200 is the main dust suction component of this building fine material pipeline transportation dust suction device, which includes a dust suction pipe 210, an elastic rope 220, a dust suction spherical shell 230, an elastic balloon 240, a rubber ball 250, and a fiber ball 260. The two ends of the dust suction pipe 210 are respectively connected to the feeding port 110 and the discharging port 120, and it is arranged in the vertical direction, with the building fine material passing through the dust suction pipe 210 from top to bottom. The dust suction spherical shell 230 is suspended in the dust suction pipe 210 through the elastic rope 220. The number of the elastic ropes 220 is specifically two, which are symmetrically installed on both sides of the dust suction spherical shell 230 respectively, making the force on the dust suction spherical shell 230 more balanced and the dust suction spherical shell 230 located in the center of the dust suction pipe 210, which can increase the contact area with the flowing building fine material, thereby improving the dust suction efficiency. The elastic balloon 240 is arranged in the dust suction spherical shell 230, and it can expand and contract due to temperature changes. A plurality of rubber balls 250 and a plurality of fiber balls 260 are loaded in the elastic balloon 240. When the dust suction spherical shell 230 is impacted by the building fine material or oscillates back and forth due to the wind pressure generated by the falling of the building fine material, the vibration drives the rubber balls 250 and the fiber balls 260 to rub and collide with each other, thereby generating heat and static electricity. The process of generating heat is the conversion of the mechanical energy of the collision between the rubber balls 250 and the fiber balls 260 into heat energy; the process of generating static electricity is that an external force causes electrons to transfer from one object to another object, making the two objects carry equal amounts of charge. The object that obtains electrons is negatively charged, and the object that loses electrons is positively charged. This static charge can have an adsorption effect on dust with small mass.

[0035] The heat causes the elastic balloon 240 to expand and fully contact the inner wall of the dust suction spherical shell 230. The static charge is transferred to the dust suction spherical shell 230 through the elastic balloon 240 and electrostatically adsorbs the dust in the dust suction pipe 210. When at rest, the heat in the elastic balloon 240 subsides, so that the elastic balloon 240 cools and contracts and releases the contact with the dust suction spherical shell 230. The static charge cannot be transferred to the dust suction spherical shell 230, causing the dust suction spherical shell 230 to stop adsorbing dust. After losing the static charge, the dust detaches from the surface of the dust suction spherical shell 230 for easy cleaning. During subsequent cleaning, clean water can be flushed into the dust suction pipe 210, and the dust accumulated on the dust suction spherical shell 230 can be knocked off by the impact of the water flow to prepare for the next dust suction work.

[0036] Furthermore, ammonium chloride powder 270 is also filled in the elastic balloon 240. When the rubber balls 250 and the fiber balls 260 collide to generate heat, the heat promotes the decomposition of the ammonium chloride powder 270 and generates ammonia gas. The volume of the gas in the elastic balloon 240 becomes larger, promoting the faster expansion of the elastic balloon 240, so that it can come into contact with the dust suction spherical shell 230 faster and enter the dust suction working state. It is easy to understand that other substances that can decompose into gases when heated can also be used, which will not be elaborated here.

[0037] Furthermore, the elastic balloon 240 is also filled with static electricity isolating powder 280, which is specifically powder ground from an anti-static acrylic plate and has the function of isolating static charges. The principle is to form a conductive layer on the material surface to reduce the surface resistivity, thereby quickly leaking the charges generated by static electricity. It is easy to understand that other materials capable of isolating static electricity can also be used, which will not be elaborated here. The purpose of filling the elastic balloon 240 with the static electricity isolating powder 280 is to cancel the dust suction effect of the dust suction spherical shell 230 more quickly during static state, so as to facilitate cleaning. Only when the static charges in the elastic balloon 240 reach the threshold can the static adsorption effect be generated.

[0038] Furthermore, a dust suction pad 211 is laid on the inner wall of the dust suction pipe 210, which is specifically a plant fiber cushion layer and can also generate static charges during contact with building fine materials, so as to adsorb the building fine material dust flowing in the dust suction pipe 210 together with the dust suction spherical shell 230, improving the adsorption efficiency of dust.

[0039] Next, the working process of this building fine material pipeline transportation dust suction device will be introduced:

[0040] S100. Building fine materials enter the dust suction pipe 210 from the feeding port 110. The impact of the building fine materials and the generated wind pressure cause the dust suction spherical shell 230 to oscillate back and forth in the dust suction pipe 210;

[0041] S200. The rubber ball 250 and the fiber ball 260 in the elastic balloon 240 collide with each other. The generated heat causes the ammonium chloride powder 270 to generate ammonia to promote the expansion of the elastic balloon 240 until the elastic balloon 240 is in full contact with the inner wall of the dust suction spherical shell 230. The static charges generated by the friction between the rubber ball 250 and the fiber ball 260 are transmitted to the dust suction spherical shell 230 through the elastic balloon 240. The charged dust suction spherical shell 230 adsorbs the dust of the surrounding building fine materials;

[0042] S300. After the dust suction work is completed, the dust suction spherical shell 230 is stationary. The inside of the elastic balloon 240 gradually cools down and begins to shrink. The static electricity isolating powder 280 isolates the static charges, causing the dust suction spherical shell 230 to cancel the adsorption of dust, facilitating subsequent cleaning.

[0043] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
