[0095] The second arc-shaped side cover 30-1-2 is used to support the conveyor 100, which is conducive to connecting and arranging the conveyor 100;

[0096] An adapter 30 is provided. The adapter 30 is composed of two half joints 30-1. The flexibility during assembly is relatively good, which is conducive to supporting the conveyor 100. After the two half joints 30-1 are assembled, a sealant is applied to the gap between the two half joints 30-1 to ensure sealing.

[0097] The number of adapters 30 and dust suppression members 20 needs to be set according to the length of the conveyor 100. Generally, the combined length of the adapters 30 and dust suppression members 20 is at least 80% of the length of the conveyor 100 to ensure the dust suppression effect.

[0098] Implementation 5: Figure 1 、 Figure 2 、 Figure 10 When implemented, the recovery pool 40-1 is provided on the foundation 200, and has a rectangular structure, and the depth of the recovery pool 40-1 gradually deepens from left to right (eg Figure 2 As shown), it is helpful for operators to clean up dust;

[0099] The duct 40-2 is L-shaped, with one end connected to the fan 20-6 and the other end extending into the recovery tank 40-1 and immersed in the non-toxic liquid, which helps to guide the dust into the non-toxic liquid to form a suspension.

[0100] The other end of the conduit 40-2 is blocked, and a plurality of aeration holes are provided on the side wall, which increases the contact area between the dust and the non-toxic liquid, making the contact more complete and facilitating the formation of a suspension;

[0101] The cover plate 40-3 is a plate-shaped structure, which is sequentially placed on the recovery pool 40-1 to cover the recovery pool 40-1, forming the first barrier to prevent dust from overflowing and being relatively beautiful;

[0102] The sealing cover 40-4 includes: two half-cover bodies 40-41, the bottom of each half-cover body 40-41 is connected to the foundation 200, clamps the conduit 40-2, and covers the other end of the conduit 40-2 and the cover plate 40-3; the half-cover body 40-41 is a half-structure, which is relatively easy to assemble. After assembly, a sealing sticker is affixed to the gap between the half-cover bodies 40-41. The sealing cover 40-4 forms a second barrier to ensure sealing and prevent dust from overflowing;

[0103] The half cover 40-41 is made of plastic, such as a transparent acrylic plate. After assembly, a sealed space 40-5 is formed between the foundation 200, the conduit 40-2, and the cover 40-3. This helps prevent dust from overflowing and locks the conduit 40-2 in place. At the same time, the operator can see the situation in the sealed space 40-5, which provides relatively good flexibility in use.

[0104] Since the dust includes dust and fly ash, fly ash is insoluble in water and forms a suspension in water. After standing for a long time, most of the fly ash will settle to the bottom of the water, and a small amount of light fly ash and dust will float on the water surface. The operator opens the sealing cover 40-4 and the cover plate 40-3, and uses tools (such as a spoon, a shovel, a water pump, etc.) to pump out the water in the recovery tank 40-1 with a water pump, and then fishes out the remaining fly ash. After the fly ash is processed, it is recycled for secondary use, such as as an admixture for concrete to adjust the working performance and strength of concrete, or modified and used in wastewater treatment and other fields by utilizing its adsorption properties. This realizes the recycling and reuse of fly ash and makes full use of limited resources.

[0105] Structure in the prior art:

[0106] See Figure 1 、 Figure 2 The conveyor 100 and the foundation 200 are commonly used structures in the prior art. The conveyor 100 is a belt conveyor for conveying coal. The coal moves along the conveyor 100. It is relatively convenient and intelligent to use. In addition, the horizontally arranged belt conveyor is convenient for assembly to the platform 11 and the adapter 30, and is surrounded by the dust suppression member 20 and the adapter 30. The foundation 200 is made of steel bars and poured concrete. After reading the disclosed content, ordinary technicians in this field can directly and unambiguously know how to set up the conveyor 100 and the foundation 200 without any creative work or excessive experiments.

[0107] The working principle is as follows: the coal is delivered to the conveyor 100 (for example, through an inclined screw conveyor, an operator or an intelligent robot delivers the coal into the inclined screw conveyor, and the inclined screw conveyor delivers the coal to the conveyor 100, which is relatively intelligent, relatively easy to operate, and is common knowledge). The coal moves along the conveyor 100 and passes through the dust suppression member 20. The dust enters the second inner space 20-34 from the second dust inlet 20-33-1, and then follows the first dust inlet 20-31-1 to enter the pipe mouth 20-13, and then enters the recovery pool 40-1 through the conduit 40-2. The recovery pool 40-1 contains non-toxic liquid, and the dust is retained in the non-toxic liquid, thereby suppressing the recovery of dust, protecting the surrounding working environment, and being relatively hygienic.

[0108] In the description, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", etc. indicating directions or positional relationships are based on the positional relationships shown in the drawings and are only used to facilitate or simplify the description, and do not indicate specific directions that must be maintained.

[0109] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meanings understood by persons of ordinary skill in the relevant art. The terms "first," "second," and similar words used in the specification and claims do not denote any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms "a" or "an" and similar words do not necessarily indicate a limit on quantity, but rather indicate the presence of at least one, which shall be determined based on the content of the embodiments.

[0110] The above merely provides the preferred embodiments of the present application, but the protection scope is not limited thereto, and any equivalent replacement or change according to the technical solution and the inventive concept within the disclosed technical scope should be covered within the protection scope.
