Technical Field

[0001] This utility model belongs to the field of solid material unloading and dust removal technology, specifically relating to an unloading hopper and a dust removal device. Background Technology

[0002] Cocoa beans are an important agricultural product, and their processed products are widely used in the food and beverage, cosmetics, and pharmaceutical industries worldwide. These products include cocoa liquor, cocoa butter, and cocoa powder, which are not only key raw materials for the food industry but also play an important role in daily life.

[0003] The main processing steps of cocoa beans include fermentation, drying, roasting, shelling, and grinding. These steps are crucial to ensuring the quality and taste of the final product. Cocoa bean processing capacity is mainly concentrated in Europe and America, with raw materials primarily sourced from Africa. After being purchased from plantations, the raw materials need to be cleaned, dried, and repackaged. Several problems have been identified during this process, such as: high breakage rate during unloading before cleaning; and significant dust generation during unloading, which is environmentally unfriendly and exposes workers to prolonged exposure to dust, posing a risk of dust explosion should an open flame be encountered. These problems directly reduce the quality of cocoa beans and affect export prices. Therefore, this application provides a corresponding unloading hopper and dust removal device to address these issues.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a discharge hopper and dust removal device to solve the problems of high breakage rate of raw cocoa beans during the discharge process and the generation of large amounts of dust, which are unfriendly to the workshop environment.

[0022] The technical solutions of the utility model patent will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative work shall fall within the scope of protection of the utility model.

[0023] In the description of the present utility model, it should be noted that terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the utility model.

[0024] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the connection inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] Refer to the attached Figure 1-4 , a discharge hopper and a dust removal device, including a discharge hopper main body and a dust removal system supporting the discharge hopper main body. Among them,

[0026] A plurality of feed hoppers 1 are provided at the top of the discharge hopper main body, and a heavy steel grille is provided on the upper surface of the feed hopper 1; evenly distributed special structure baffles are provided below the grille, including an inclined steel fixed baffle 5 and a flexible movable baffle 6; the fixed baffle is inclined; the movable baffle is vertically arranged, its top is located below the corresponding fixed baffle, and its bottom contacts the bottom of another fixed baffle.

[0027] It should be noted that since the vertically arranged movable baffle 6 rotates during the discharging process, the movable baffle 6 near the edge of the feed hopper 1 may be blocked by the frame of the feed hopper 1 and cannot move. Therefore, in this embodiment, the positions of the movable baffle 6 near the side frame of the feed hopper 1 and the fixed baffle 5 are changed. Refer to the partial enlarged view of the attached Figure 3 shown, which solves the problem that the movable baffle 6 may be blocked and cannot move.

[0028] The special design of the baffle makes the feeding hopper 1 present a sealed structure. Both ends of the fixed baffle 5 are connected to the frame of the grille plate, and the movable baffle 6 is normally in a normally closed state. When solid materials are discharged, the flexible movable baffle 6 is opened by gravity to allow the materials to pass through. Due to the function of the baffle, the dust generation during the discharging process is avoided, a large amount of treatment air volume is saved, the equipment investment is reduced, and the environmental hygiene of the operating condition is ensured.

[0029] The dust removal system supporting the main body of the discharging hopper consists of a dust removal air network 2, a dust collector, and a dust removal fan 4. Multiple air duct branches are provided on the main air duct of the dust removal air network 2, and dust removal interfaces are provided at the ends of the air duct branches; the dust removal interfaces are located at the upper part of the feeding hopper 1 at the corresponding positions; all the air duct branches form a 30-degree inclination angle with the main air duct, which is beneficial to reducing the air resistance.

[0030] Taking cocoa beans as an example, due to the special baffle structure arranged inside the main body of the discharging hopper, it plays a buffering role for cocoa beans during the discharging process and naturally falls into the hopper, which can effectively reduce the breakage rate of cocoa beans during the discharging process. This dust removal system fits tightly with the main body of the discharging hopper to form a closed dust removal during the discharging process, ensuring the environmental hygiene of the production workshop. The whole system is controlled by PLC, with good dust removal effect. The baffle with a special structure can avoid dust generation during the discharging process of cocoa beans and is friendly to the workshop environment.

[0031] In this embodiment, air inlets are arranged around the baffle close to the feeding hopper 1, which can effectively suck away the dust in the materials. The dust removal air volume is converted according to the effective space of the feeding hopper 1, the flow rate in the air duct is controlled at about 10 m / s, and a suitable cyclone dust collector 3 is selected, which can effectively remove the dust in the materials during the discharging process. When the dust removal fan 4 is turned on, the dust removal device can automatically remove dust. The cyclone dust collector 3 and the dust removal fan 4 are arranged at different heights with the main body of the discharging hopper, making the air duct in a vertical angle, which can avoid the accumulation of dust generated during the long-term use of the dust removal air network 2.

[0032] The discharging hopper and the dust removal device of the present utility model, through the special feeding baffle structure, ensure that the breakage rate is reduced when solid materials are discharged; the reasonable position of the air inlet ensures that the dust does not exceed the overflow of the discharging hopper, reduces the dust removal air volume, achieves the good effect of being friendly to the environment and saving investment. In addition, the main body of the discharging hopper and the dust removal air network 2 are all arranged under the pit, without affecting the operating space on the ground.

[0033] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations.
