Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a feed crushing dust removal device. Background Art

[0002] Feed is an industrially processed product intended for animal consumption. It comes in a variety of plant, animal, and mineral forms, including grains, legumes, fish meal, and stone dust. The feed grinding process generates significant amounts of dust, making dust removal essential. This process protects the health of operators by preventing dust-related respiratory issues. It also improves feed quality by preventing dust from entering the feed, causing uneven particle size and absorbing moisture and microorganisms, leading to mold and deterioration. It also helps prevent dust explosions. Many feed ingredients contain flammable dust, which can explode at certain concentrations when exposed to ignition. Dust removal reduces dust concentrations to a safe level. Furthermore, it meets environmental requirements, preventing dust emissions from polluting the surrounding environment and violating regulations.

[0003] Feed grinders generally include hammer feed grinders, claw feed grinders, roller grinders, double-rotor grinders, water drop grinders, and flattening grinders. Claw feed grinders use high-speed rotating claws to crush feed; the claws rotate at a high speed, which can produce a strong shearing and crushing effect on the feed;

[0004] When existing claw-type feed crushers crush straw feed, in most cases, the straw is directly put into the feed inlet and the machine is started to crush the feed. However, since some straw feed will collide at high speed inside the machine during crushing, it will cause a lot of dust, which affects the cleanliness of the working environment. In the existing technology, only a single protective cover is usually used to protect it from dust splashing, but the single dust cover still causes the problem of dust splashing everywhere. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a feed crushing and dust removal device, which aims to improve the problem in the prior art that dust cannot be prevented from splashing and the dust cannot be efficiently filtered before being discharged.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feed crushing and dust removal device, comprising a crusher, the crusher is connected to a feed hopper, a protective cover is fixedly connected to the feed hopper, a processing box is fixedly installed on one side of the crusher, a partition is provided in the processing box to separate the inner cavity of the processing box into two upper and lower sections, a collecting component connected to the upper section of the processing box is installed on the top of the processing box, the collecting component is connected to the protective cover for collecting dust, a collection box is slidably connected to the interior of the upper section of the processing box, and a filter dust collector is provided in the collection box. A dust filtering component is provided, and an air outlet is provided on the side wall of the processing box below the filtering component and above the partition; a water tank is provided in the lower section of the processing box, and a transmission component for transmitting liquid is connected to the water tank, and the dust reduction component includes a water pump, which is fixedly installed on the processing box, and the water inlet end of the water pump is connected to the water tank through a connecting pipe, and the water outlet end of the water pump is connected to a transmission pipe, and the other end of the transmission pipe is provided inside the protective cover, and the transmission pipe is connected to a plurality of diversion pipes, and the plurality of diversion pipes are provided with quick-release nozzle assemblies for easy replacement.

[0007] Furthermore, the collection component includes a fan, which is fixedly mounted on the processing box. The air outlet of the fan is connected to the upper section of the processing box through pipe 1, and the air inlet of the fan is connected to pipe 2, the other end of which is fixedly connected to the inside of the protective cover.

[0008] Furthermore, the filter assembly includes ventilation holes arranged through the interior of the collection box, the inner wall of the collection box is fixedly connected to a support plate, positioning rods are fixedly connected to the support plate located at the four corners of the collection box, and an installation frame is installed in the collection box through the positioning cooperation of the four positioning rods, and a filter net is installed in the installation frame.

[0009] Furthermore, a scale line for observing the water level of the water tank is provided on the side wall of the treatment tank.

[0010] Furthermore, the quick-release nozzle assembly includes a nozzle, one end of which is connected to the diversion pipe, and the outer wall of the other end is provided with an external thread, and a threaded cover is threadedly connected to the external thread, and a barrier net is provided in the threaded cover.

[0011] The utility model has the following beneficial effects:

[0012] 1. In the utility model, a protective cover is used to prevent a large amount of dust from splashing, and the dust near the protective cover is transferred to the inside of the pipe one through the fan through the pipe two. At this time, the dust is transferred to the inside of the processing box through the pipe one, thereby achieving the effect of preventing dust from splashing. At this time, the dust is collected and filtered through the filter, and the clean air flow is discharged from the inside of the processing box through the ventilation holes and the air outlet, thereby achieving the effect of further filtering the dust for discharge. After long-term use, the filter can be replaced by pulling the collection box, thereby improving the practicality of the device.

[0013] 2. In the utility model, an appropriate amount of urea solution is added to the water tank, and then the solution in the water tank is transferred to the inside of the transmission pipe through a water pump through a connecting pipe. At this time, the solution is transferred to the inside of the nozzle through a diversion pipe through the transmission pipe for spraying, thereby achieving the effect of quickly mixing and adhering the solution and the feed. The protein content of the feed can be increased by adding an appropriate amount of urea solution. At this time, the barrier net can be used to prevent the feed from splashing and clogging the nozzle. When the barrier net needs to be cleaned, the threaded cover is disengaged from the external thread by rotating the threaded cover, so that the barrier net can be removed for cleaning. This solves the problem of the need to add additional equipment to add nutrient solution in the prior art, which increases costs, thereby improving the practicality of the device.
