They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Based on the aforementioned background technology, it can be seen that during the production process of aquatic extruded feed, the dried feed (also referred to as material in this application) easily generates a large amount of dust, which can easily pollute the environment. Therefore, this utility model proposes a dust removal device for the production of aquatic extruded feed to fully solve the dust pollution problem.

[0035] Please refer to the following: Figure 1 , Figure 2 The dust removal device for aquatic extruded feed production according to an embodiment of the present utility model includes:

[0036] The drying mechanism 10 includes a drying tank 101 and an inlet 102 and an outlet 103 connected to the drying tank 101.

[0037] The ventilation mechanism 20 includes a fan 201 and a ventilation duct 202 connected to the fan 201 and an exhaust port 203. The ventilation duct 202 is connected to the top of the drying tank 101.

[0038] The three-dimensional dust removal mechanism 30 includes a fixed frame 301 and a first filter chamber 302 and a second filter chamber 306 arranged from bottom to top on the fixed frame 301.

[0039] The upper part of the first filter bin 302 is connected with the air outlet 203 through the spiral air inlet pipe 304, and the bottom of the first filter bin 302 is provided with a detachable dust collecting seat 303; the second filter bin 306 is located above the first filter bin 302, and a partition seat 311 is arranged in the second filter bin 306 to form a first filter cavity and a second filter cavity distributed from bottom to top; the bottom of the first filter cavity is connected with the first filter bin 302 through the transition pipe 305, and the top of the first filter cavity is connected with the second filter cavity through the air vent or air groove pre-set on the edge of the partition seat 311; the bottom of the partition seat 311 is connected with the dust collecting pipe 310, the dust collecting pipe 310 penetrates into the first filter bin 302 through the transition pipe 305 and abuts against the dust collecting seat 303; and the top of the second filter bin 306 is provided with a cyclone dust removal structure acting on the second filter cavity.

[0040] It can be understood that the partition seat 311 extends to the working cavity sidewall connected with the second filter bin 306 through the upper end edge, thereby separating the working cavity into the first filter cavity and the second filter cavity, and the second filter cavity is located above the first filter cavity. In this way, the main body of the partition seat 311 is located in the first filter cavity, and a gap is reserved between the circumferential sidewall of the partition seat 311 and the sidewall of the first filter cavity, so that the airflow in the first filter bin 302 can flow into the first filter cavity through the gap and then flow into the second filter cavity through the air vent or air groove pre-set on the upper end extension edge of the partition seat 311. The bottom of the partition seat 311 is connected with the dust collecting pipe 310, so as to collect the fine particulate matter and dust filtered by the cyclone dust removal structure and send them into the dust collecting seat 303 for unified recycling.

[0041] Obviously, according to the dust removal device for aquatic puffed feed production, the first filter bin 302 and the second filter bin 306 distributed in a three-dimensional state are used for twice filtration, wherein the first filtration in the first filter bin 302 can make the coarse particulate matter in the dust airflow directly settle to the dust collecting seat 303 under the action of gravity; and then the second filtration in the second filter bin 306 can further process the fine particulate matter and dust in the dust airflow and make them fall into the dust collecting seat 303 for collection. In this way, the material particles in the dust can be effectively recycled while the dust is efficiently purified and dried, so as to achieve the purpose of saving resources and protecting the environment.

[0042] It can be understood that the airflow flow of the entire dust removal device (please refer to Figure 2The air flow direction) is mainly driven by the ventilation mechanism 20 and the cyclone dust removal structure. Specifically, the ventilation mechanism 20 drives the air flow by the fan 201, so that the dust in the drying tank 101 can enter the first filter bin 302 with the air flow flowing into the discharge port 103 at the bottom of the drying tank 101. The cyclone dust removal structure located at the top of the second filter bin 306 can filter while driving the air flow. Obviously, compared with the air flow rate and pressure when the dust in the suction drying tank 101 is sucked, the air flow rate and pressure when the first filter bin 302 flows into the second filter bin 306 should be appropriately larger, and the air flow state of the first filter bin 302 into the second filter bin 306 should be suitable for the settlement of coarse particles.

[0043] Optionally, one end of the air inlet pipe 304 is detachably connected with the exhaust pipe 203, and the air inlet pipe 304 spirally extends downward around the outside of the first filter bin 302 for one or more turns and is connected in the first filter bin 302. At the same time, the part of the air inlet pipe 304 connected with the first filter bin 302 is preferably provided with a downward opening to facilitate the flow of dust air flow towards the bottom of the first filter bin 302, thereby facilitating the rapid falling of coarse particles in the dust into the dust collecting seat 303.

[0044] Optionally, the dust collecting seat 303 is provided with active adsorption or filtering material to further improve the filtering efficiency.

[0045] Please refer again to Figure 1 and Figure 2 In some embodiments of the present application, the cyclone dust removal structure includes an exhaust seat 308, an exhaust driving member 309, and a plurality of dust removal cloth bags 312. The exhaust seat 308 is arranged at the top end of the second filter cavity and is connected with the exhaust driving member 309. The plurality of dust removal cloth bags 312 are uniformly distributed at the air inlet end of the exhaust seat 308.

[0046] It can be understood that the exhaust seat 308 and the exhaust driving member 309 actually constitute a centrifugal fan. The central part of the exhaust seat 308 has a centrifugal fan, the rotating shaft of the centrifugal fan is located at the center of the exhaust seat 308, and the rotating shaft of the centrifugal fan is in transmission connection with the exhaust driving member 309. In this way, the exhaust driving member 309 can control the rotation of the centrifugal fan when it rotates, thereby driving the air flow in the second filter bin 306 to flow out of the exhaust seat 308. During the flow process, the air flow must pass through the dust removal cloth bag 312 to enter the air inlet end of the exhaust seat 308, so that the dust removal cloth bag 312 can adsorb and filter the air flow passing through, thereby playing the role of secondary filtration of the second filter bin 306.

[0047] Please refer again to Figure 2In some embodiments of the utility model, cyclone dust removal structure still includes pulse dust collector 307, the output of pulse dust collector 307 is connected with the air inlet end of exhaust seat 308.

[0048] It can be understood that after the exhaust seat 308 stops working, the airflow in the exhaust seat 308 and the second filter bin 306 stops flowing (or the flow is very weak), and when the pulse dust collector 307 emits a pulse high-pressure airflow, it can directly act on the dust cloth bag 312, so that the dust and light particles adsorbed on the dust cloth bag 312 fall off and fall into the dust collection pipeline 310 through the partition seat 311, and then fall into the dust collection seat 303 for recycling or cleaning.

[0049] Please refer again to Figure 2 In further embodiments of the utility model, the air inlet cavity is arranged at the air inlet end of the exhaust seat 308, the air inlet cavity is located at the top of the second filter cavity, a plurality of dust cloth bags 312 are uniformly distributed at the bottom of the air inlet cavity, and the output of the pulse dust collector 307 is connected with the air inlet cavity. In this way, the pulse high-pressure airflow emitted by the pulse dust collector 307 can act on the dust cloth bag 312 through the air inlet cavity, so as to sufficiently improve the pulse dust removal effect.

[0050] Please refer again to Figure 1 With Figure 2 In some embodiments of the utility model, the first filter bin 302 is a conical tank body with a wide top and a narrow bottom, and the dust collection seat 303 is connected to the bottom end of the conical tank body by threads, screws or threaded connections. In this way, the coarse particles in the dust can fall into the dust collection seat 303 along the narrow sidewall of the conical tank body, thereby improving the dust removal effect.

[0051] Please refer again to Figure 1 With Figure 2 In some embodiments of the utility model, the sidewall of the first filter cavity and the partition seat 311 are arranged as coaxially distributed conical hopper bodies, and the central axis of the conical hopper body coincides with the rotation center of the cyclone dust removal structure. Obviously, the first filter cavity and the partition seat 311 are coaxially arranged, and the gap between the sidewalls of the corresponding conical hopper bodies is uniform. After the dust airflow is filtered once, it needs to flow further in an inclined upward direction when flowing upward from the first filter bin 302 to the first filter cavity. This increases the difficulty of the coarse particles flowing upward with the airflow, thereby improving the preliminary filtering effect of the coarse particles.

[0052] Please refer again to Figure 1 In some embodiments of the utility model, the drying mechanism 10 and the ventilation mechanism 20 can be detachably arranged on the fixed frame 301, so as to further provide a whole combined dust removal device for aquatic expanded feed production, which can sufficiently reduce the floor area.

[0053] Please refer againFigure 1 In further embodiments of the present application, the fixed frame 301 is provided with a first connecting frame and a second connecting frame on one side, the drying tank 101 is detachably connected to the first connecting frame, and the fan 201 is detachably connected to the second connecting frame. In this way, the drying tank 101 and the fan 201 can be detachably combined on the fixed frame 301.

[0054] Please refer to Figure 3 In some embodiments of the present application, the discharge port 103 is located at the bottom of the drying tank 101, and the feeding port 102 is located at the upper part of the drying tank 101. In this way, the material can fall into the upper part of the drying tank 101 and flow out of the bottom of the drying tank 101, so that the generated dust can be taken away by the airflow generated by the ventilation mechanism 20 on the basis of sufficient drying of the material.

[0055] Please refer to Figure 3 In some embodiments of the present application, the feeding port 102 is provided with a hopper near the outer side of the drying tank 101, and a material guiding slope is arranged near the inner side of the drying tank 101. The cooperation of the hopper and the material guiding slope can make the material fully dispersed when entering the drying tank 101, thereby ensuring the drying effect and dust removal effect.

[0056] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present application.
