Description

Technical Field

[0001] The utility model relates to a rotary material distributing machine, in particular to a fully sealed rotary material distributing machine for a silo, belonging to the technical field of silo rotary material distributing machines. Background Art

[0002] Silo rotary spreading machines are primarily used in large coal storage silos in thermal power plants, coal mines, docks, chemical plants, and other fields to achieve uniform material distribution. They improve silo volume utilization, ensuring uniform and continuous material flow until the silo is full. Furthermore, when used in conjunction with several silos, they can coordinate the use of high-quality and low-quality coal grades, improving the overall utilization of coal quality and enhancing the overall economic benefits of the power plant.

[0003] The silo rotary material distributor works by conveying material into an inverted tee via a belt conveyor. The material then falls through the inverted tee onto a reversible belt conveyor. The belt conveyor rotates forward to discharge material into the outer ring, while reverse rotation discharges material into the inner ring. The material is then discharged into the inner and outer annular grooves of the silo via the head and tail hoppers at both ends of the belt conveyor, achieving uniform material distribution within the silo.

[0004] Distributing material into the silo through the inner and outer ring feed openings fully utilizes the silo's capacity, maximizing its capacity. However, due to relative rotation, the discharge openings at each end of the rotary distributor move relative to the inner and outer ring feed openings on the silo roof, making sealing difficult. When the rotary distributor discharges material into a specific location on the inner or outer ring feed opening, all other feed openings except the discharge point become pressure relief vents. The silo's pressure relief requirements dictate that the inner and outer ring feed openings cannot be completely sealed.

[0005] There are also existing technologies that use simple structures to try to achieve a fully sealed rotary cloth for the silo. The common practice is to add a circle of rubber around the body frame for simple sealing. This solution effectively reduces the escape of dust. However, due to the loose fit between the rubber and the silo body and the gap, and long-term friction with the silo body, it is severely worn and deformed. If it is not replaced in time, a large amount of dust will escape, causing serious environmental pollution, and it is difficult to take into account pressure relief. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] This embodiment specifically provides a fully enclosed and environmentally friendly rotary material placing machine for a silo, and applies it to material placing in silos, especially high-storage silos, to achieve material placing operations in the silo under completely sealed conditions, and solve the problem of a large amount of dust escaping from the silo roof and causing serious environmental pollution during material placing. This ensures that there is no dust emission during material placing in the silo, the air is clean, and environmental protection standards are met.

[0027] The specific technical solutions are as follows:

[0028] The currently commonly used open rotary concrete placing machine is changed into a fully enclosed rotary concrete placing machine. A rotary sealing device is set at the feeding port of the fully enclosed rotary concrete placing machine to ensure that the fully enclosed rotary concrete placing machine is completely sealed when receiving materials and no dust escapes.

[0029] The fully enclosed rotary concrete placing machine is placed on the top of the silo, with the rotation center coinciding with the silo center. It also uses a circular track and is equipped with inner and outer ring discharge ports. The silo feed port and the fully enclosed rotary concrete placing machine's discharge port are improved as follows:

[0030] a) Set four full circles of water storage sealing grooves 2 on the edges of the inner and outer ring feed openings of the silo, such as Figure 1 shown.

[0031] b) A closed rotary dustproof cover 3 is set at the discharge port of the fully enclosed rotary feeder. The cover completely closes the inner and outer ring feed ports on the top of the silo, and a stop with a roller is inserted into the water storage sealing groove 2 to ensure tight side sealing.

[0032] c) The cover 3 is fixed on the fully enclosed rotary concrete placing machine and rotates along with the fully enclosed rotary concrete placing machine.

[0033] d) A dust removal pressure relief port 4 with a multi-layer filter dust removal net or dust removal bag is provided above the discharge port at both ends of the fully enclosed rotary concrete placing machine to ensure dust removal while relieving pressure and meet emission standards.

[0034] e) The dust removal and pressure relief device 4 of the fully enclosed rotary concrete placing machine is equipped with an ash storage tank, which can be cleaned regularly to ensure smooth and reliable operation of the equipment.

[0035] The main components of the silo fully enclosed rotary feeder are: 1-rotating sealing device, 2-four full-circle water storage sealing grooves on the silo roof, 3-enclosed rotary dust cover (with a stop with roller), 4-dust removal pressure relief port with multi-layer filter dust removal net or dust removal bag, 5-dust cleaning device, 6-fully enclosed rotary feeder body, etc. Figure 1 、 Figure 2 shown.

[0036] The following is combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 This embodiment is described in further detail:

[0037] Different from most open concrete placing booms currently available, the silo fully enclosed rotary concrete placing boom adopts a fully enclosed structure:

[0038] like Figure 1 As shown, the feed port is sealed by a rotary sealing device 1, and the fully enclosed rotary material distributor body 6 is a sealed structure.

[0039] like Figure 4 As shown, the discharge port and the closed rotary dust cover body 6 are connected by a flange 303, which is also a closed structure.

[0040] like Figure 3 As shown, the four water storage sealing grooves and the closed rotating dust cover are a full-circle ring structure. This structural form can well adapt to the rotary motion and facilitate the realization of sealing.

[0041] like Figure 4 、 Figure 5 As shown, the water storage sealing groove 2 completely surrounds the silo feed port, and the closed rotating dust cover 3 is completely buckled in the water storage sealing groove 2.

[0042] like Figure 5 As shown, a water seal 201 is used between the enclosed rotary dust cover 3 and the water storage sealing groove 2, achieving a complete seal between the silo and the fully enclosed silo rotary material distributor. Rollers 302 are attached to the enclosed rotary dust cover 3, ensuring that the enclosed rotary dust cover 1 rotates under the drive of the fully enclosed silo rotary material distributor.

[0043] The fully enclosed rotary concrete placing boom can relieve the pressure of the silo while placing the material.

[0044] like Figure 1 、 Figure 2 As shown, the fully enclosed rotary material distribution machine of the silo is provided with a dust removal pressure relief port 4 at each unloading point at both ends, and the silo pressure is relieved while unloading to ensure stable and reliable material distribution.

[0045] The fully enclosed rotary concrete placing boom of the silo has the function of environmentally friendly dust removal.

[0046] The fully enclosed structure can ensure that dust does not escape.

[0047] The pressure relief port is an environmentally friendly pressure relief port, and a dust removal pressure relief device 4 is provided, namely a multi-layer filter dust removal net or dust removal bag, which uses the warehouse pressure during unloading to filter and remove dust.

[0048] like Figure 1 As shown, a dust cleaning device 5 is provided inside the fully enclosed rotary material distributor of the silo, which can clean the dust accumulated inside the equipment and ensure the reliable and clean operation of the equipment.

[0049] In this way, the fully enclosed silo rotary feeder achieves full closure of the silo, which not only fully utilizes the silo volume, but also ensures that there is no dust emission in the silo area, the air is clean, and environmental protection standards are met.

[0050] In this embodiment, an ash storage tank is provided below the dust removal pressure relief device 4 and can be cleaned regularly or irregularly.

[0051] In this embodiment, a dust cleaning device 5 is provided below the conveyor belt inside the rotary material distribution machine body 6 .

[0052] In this embodiment, the gap between the sealing rotary dustproof cover 3 and the upper edge of the water storage sealing groove 2 is 5-15 cm.

[0053] The fully enclosed rotary feeder for silos provided in this embodiment realizes the full closure of silos, which solves the problem of unorganized emissions; the dust removal pressure relief port with multi-layer filtering dust removal nets or dust removal bags solves the pressure relief problem caused by the downward movement of materials during ore unloading, ensuring the realization of clean production and environmental protection standards; the water storage sealing groove, the sealing rotating dust cover, and the connecting flange provided at the edge of the sealing rotating dust cover ensure that the entire structure has high rigidity and strong resistance to deformation and impact. Compared with the existing simple sealing structure, it truly realizes stable and safe production under full sealing.

[0054] The above are preferred embodiments of the present invention. Ordinary technicians in this field can also make various changes or improvements on this basis. Without departing from the overall concept of the present invention, these changes or improvements should fall within the scope of protection required by the present invention.
