Description

Technical Field

[0001] This utility model relates to the field of temperature control technology, specifically to a dust removal device for production. Background Technology

[0002] Aquaculture-specific emulsifiers are a class of emulsifiers specifically used in aquaculture and seafood processing. They reduce interfacial tension, enabling immiscible liquids to form stable emulsions, and have a variety of important applications in the aquaculture industry.

[0003] In aquatic feed, oils and water are immiscible. Adding emulsifiers can promote the uniform dispersion of oils in the feed, forming a stable emulsion structure, improving oil utilization, and enhancing nutrient absorption. For example, adding emulsifiers to eel feed can evenly disperse fat particles, helping eels better digest and absorb fat, promoting growth, and reducing the feed conversion ratio. During the processing of aquatic pellet feed, due to the lack of dust removal facilities, dust from the raw materials and generated dust fly everywhere, polluting the environment and affecting feed quality.

[0004] A prior art patent, CN111841187A, discloses a solution comprising a base plate, an adjusting component, a dust collection component, a filter component, and a suction fan. Support pillars are fixed at the four corners of the top of the base plate, and the tops of the four sets of support pillars are connected to the top plate. A discharge component and a handrail are fixed to the top of the base plate. The adjusting component, the filter component, and four sets of rectangularly arranged support legs are fixed to the top of the top plate. The tops of the four sets of support legs are connected to a storage tank. A cover plate and a stirring component are fixed to the top of the storage tank. The adjusting component is connected to the filter component via a connector, and a dust collection component is fixed to the top of the adjusting component. The dust collection component is connected to the filter component via a first valve. The storage tank is connected to a second valve via a bend, and the second valve is connected to the filter component. A suction fan is located on the side of the filter component away from the adjusting component. This high-efficiency dust removal device for aquatic pellet feed processing can remove dust from the feed, protecting the environment.

[0005] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0006] First, during the transportation of existing aquatic feed, the presence of powder mixed in with the feed makes it difficult to separate the powder from the feed pile due to limitations in the dust removal structure. This results in the powder being easily introduced into the packaging bag during the packaging process, affecting the packaging quality of the product.

[0007] Secondly, after the existing dust removal structure removes dust, the dust tends to accumulate on the filter structure, requiring operators to clean and maintain it regularly, which reduces the dust removal efficiency for aquatic feed.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a dust removal device for production, which solves the problem that in traditional technologies, during the transportation of aquatic feed, the powder contained in the aquatic feed cannot be separated from the feed pile due to the limitations of the dust removal structure. This results in the powder being easily introduced into the packaging bag during the packaging process, affecting the packaging quality of the product.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A dust removal device for production includes a rotating conveyor belt, a dust collection box located below the conveyor belt, an opening at the upper end of the dust collection box, and a plurality of striking rollers arranged side by side inside the dust collection box along the moving direction of the conveyor belt. The striking rollers are alternately raised and lowered vertically, and when the striking rollers move to the highest position, they lift up the conveyor belt.

[0012] A filter screen is horizontally fixed inside the dust collection box. The filter screen is located below the striking roller. A cleaning plate is horizontally slidably provided on the upper surface of the filter screen to make frictional contact with it.

[0013] As an optimized solution, the lower end of the dust collection box is connected to a negative pressure suction cylinder in a tapered manner.

A roller seat is fixed to the upper end of the guide column, and the striking roller is rotatably mounted on the roller seat.

[0015] As an optimized solution, the guide rod has a guide hole corresponding to each guide post, and the guide post is slidably disposed in the guide hole along the vertical direction.

[0016] As an optimized solution, a crankshaft is rotatably mounted between the relative inner walls of the dust collection box, a hinge sleeve is hinged to the eccentric block of the crankshaft, a connecting rod is fixed to the hinge sleeve, and the other end of the connecting rod is hinged to the lower end of the guide column.

[0017] As an optimized solution, an upper drive motor is fixedly connected to the outer wall of the dust collection box, and the output shaft of the upper drive motor is connected to one end of the crankshaft.

[0018] As an optimized solution, a lead screw is provided between the relative inner walls of the dust collection box, and the lead screw is threadedly connected to the cleaning plate.

[0019] As an optimized solution, a powder collection box is fixed to the outer wall of the dust collection box, and a discharge port communicating with the powder collection box is opened on the side wall of the dust collection box.

[0022] As an optimized solution, a lower drive motor is fixedly connected to the outer wall of the dust collection box, and the output shaft of the lower drive motor is connected to one end of the lead screw.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] By driving a crankshaft to alternately raise and lower several striking rollers vertically, the conveyor belt is alternately struck, which vibrates and disperses the aquatic feed conveyed on the upper surface of the conveyor belt. The powder will fall through the conveyor belt into the dust collection box for collection, which improves the dust removal efficiency of powder from aquatic feed.

[0025] The lower end of the dust collection box is tapered and connected to a negative pressure suction cylinder, which enables suction through negative pressure, further improving dust removal efficiency.

Later, the powder inside can be discharged by opening the sealing plate, which is convenient and quick. Attached Figure Description
