Description
Technical Field
[0001] The utility model relates to the technical field of head funnels, in particular to an environment-friendly head funnel with a movable sealing door. Background Art
[0002] The head funnel is an important transfer device of the belt conveyor, and the materials conveyed on the belt conveyor are transferred to the lower equipment through the funnel.
[0003] As recorded in the "DTⅡ Type Fixed Belt Conveyor Design and Selection Manual" and the "DTⅡ(A) Type Belt Conveyor Design Manual", most of the current head funnels are as Figure 4 shown, in which the steel plate A under the tension pulley of the belt conveyor 20 and the funnel body 10 are of an integral welded structure. During actual operation, since it is difficult to completely discharge the materials on the outer surface of the belt conveyor 20 during the process of feeding materials into the funnel body 10, as Figure 4 shown, when the belt surface of the belt conveyor 20 moves downward, some materials will fall onto the cleaning platform 60; at this time, an automatic scraper cleaning device 30 is often equipped to clean the materials on the cleaning platform 60. In the existing head funnel structure equipped with the automatic scraper cleaning device 30, in order to enable the automatic scraper cleaning device 30 to sweep the materials on the cleaning platform 60 into the funnel body 10, the steel plate A above the cleaning platform 60 and below the tension pulley is cut off, so as to form an open mouth at the position of the steel plate A. However, obviously, the setting of the open mouth causes dust to overflow when the funnel is normally feeding materials. Although a dust-proof curtain for blocking dust can be set during actual implementation, since the automatic scraper cleaning device 30 needs to be cleaned frequently, the dust-proof curtain needs to be opened frequently, resulting in a still large amount of overflowing dust, which cannot meet the requirements of environmental protection for dust emission, so it needs to be solved urgently. Content of the Utility Model
[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides an environment-friendly head funnel with a movable sealing door, which can reduce the frequency of opening of the open mouth and can realize the cleaning of materials into the funnel body on the premise of meeting the requirements of environmental protection for dust emission.
[0005] To achieve the above object, the utility model provides the following technical solutions:
[0006] An environmentally friendly head hopper with a movable sealing door, comprising a hopper body and an open opening provided on the side wall of the hopper body. The outside of the open opening is hinged with a sealing door through a top horizontal hinge seat, and the axis of the top horizontal hinge seat is parallel to the door panel surface of the sealing door; a scraper for scraping materials of a belt conveyor is installed on the outer side of the upper part of the sealing door. The inside of the sealing door has a material guiding channel that penetrates up and down. In the closed state where the sealing door is vertically distributed, a storage cavity for receiving materials is formed by combining the material guiding channel and the cleaning platform at its bottom; in the open state where the bottom of the sealing door rotates and inclines inward, the bottom of the material guiding channel is misaligned with the cleaning platform, and materials are discharged into the hopper body.
[0007] As a further scheme of the utility model: the inner door panel of the sealing door adjacent to the hopper body consists of a fixed plate and a movable plate distributed up and down. The fixed plate is integrally fixed with the sealing door, and the fixed plate and the movable plate are hinged to each other through a hinge so that the movable plate can rotate towards the hopper body.
[0008] As a further scheme of the utility model: elastic sealing members elastically abutted against the cleaning platform are arranged at the bottoms of the two side door panels and the outer door panel of the sealing door.
[0009] As a further scheme of the utility model: the elastic sealing member is a rubber pad.
[0010] As a further scheme of the utility model: the hopper body is provided with an elastic reset member for driving the sealing door to reset to the closed state.
[0011] As a further scheme of the utility model: the scraper is a polyurethane plate detachably installed on the sealing door.
[0012] As a further scheme of the utility model: a reinforcing rib in the form of a grid frame structure is fixed on the outer door panel of the sealing door.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] 1. With the sealing door as the sealing structure of the open opening, it is not only convenient to open, but also the material guiding channel in the sealing door can form a storage cavity with the cleaning platform, which can realize the storage of materials; in addition, the discharging of materials in the storage cavity and the cleaning operation of the automatic scraper cleaning device are carried out synchronously, effectively reducing the opening frequency of the open opening, so that the hopper body meets the environmental protection emission requirements.
[0015] 2. The inner door panel of the sealing door adjacent to the funnel body is composed of a fixed plate and a movable plate distributed vertically. The hinged connection mode of the movable plate enables the material stored in the storage cavity to generate a force on the movable plate. When the force reaches a predetermined thrust that can push the movable plate to rotate, the automatic discharge of the material in the storage cavity can be realized without opening the sealing door. Thus, the capacity of the storage cavity is indirectly increased, and the cycle of opening the sealing door for discharging materials is further extended.
[0016] 3. Elastic seals that elastically abut against the cleaning platform are provided at the bottoms of both side door panels and the outer door panel of the sealing door. On the premise of enabling the sealing door to open and close stably, the sealing performance between the bottom of the sealing door and the cleaning platform is ensured.
[0017] 4. Reinforcing ribs in the form of a grid frame structure are fixed on the outer door panel of the sealing door, enhancing the strength of the sealing door and ensuring that the sealing door can still maintain a long service life in the collision-driven opening mode between it and the automatic scraper cleaning device.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] For easy understanding, the specific structure and working mode of the present utility model are further described as follows in conjunction with the accompanying drawings:
[0025] The specific structure of the present utility model is referred to Figures 1-4 as shown. Its main structure includes a funnel body 10, an open mouth formed on the side wall of the funnel body 10, and a sealing door 40 hinged to the outside of the open mouth through a top horizontal hinge seat. Among them, the axis of the top horizontal hinge seat is parallel to the door panel surface of the sealing door 40, so that the bottom of the sealing door 40 can rotate and incline towards the funnel body 10. When the automatic scraping device 30 moves towards the funnel body 10, it can push the sealing door 40 to open, so as to realize the cleaning work of the material into the funnel body 10. Further, a scraper 41 for scraping the material of the belt conveyor 20 is installed on the outer side of the upper part of the sealing door 40, and a material guiding channel 42 that penetrates up and down is arranged inside the sealing door 40. In the closed state where the sealing door 40 is vertically distributed, a storage cavity is formed between the material guiding channel 42 and the cleaning platform 60 at its bottom to receive the material scraped from the belt conveyor 20 by the scraper 41, effectively reducing the opening frequency of the sealing door 40. When the automatic scraping device 30 needs to move towards the funnel body 10 to clean the material, after the automatic scraping device 30 pushes the bottom of the sealing door 40 to rotate and incline inward to an open state, the bottom of the material guiding channel 42 is misaligned with the cleaning platform 60, and the material is discharged into the funnel body 10, so as to realize the synchronous discharging of the storage cavity and the automatic scraping device 30, facilitating the subsequent material receiving of the storage cavity. In the present utility model, the sealing door 40, as the sealing structure of the open mouth, is not only convenient to open, but also the material guiding channel 42 that forms the storage cavity with the cleaning platform 60 can store the material; in addition, the discharging of the material in the storage cavity is synchronized with the cleaning operation of the automatic scraping device 30, effectively reducing the opening frequency of the open mouth, so that the funnel body 10 meets the environmental protection emission requirements.
[0026] Specifically, as Figure 3 shown, the scraper 41 is a polyurethane board detachably installed on the sealing door 40, so that a new scraper 41 can be replaced after the scraper 41 is worn by scraping. In addition, the polyurethane board has the advantages of high resilience, high strength and high wear resistance, and has a relatively long service life when used as the scraper 41.
[0027] On the above basis, as Figure 2As shown in the figure, the inner door panel of the sealing door 40 adjacent to the funnel body 10 is composed of a fixed plate 45 and a movable plate 43 distributed up and down. Specifically, the fixed plate 45 is integrally fixed to the sealing door 40, and the fixed plate 45 and the movable plate 43 are hinged to each other through a hinge. The hinged connection mode of the movable plate 43 enables it to rotate towards the funnel body 10 under a given thrust. Therefore, when the force generated by the material stored in the storage cavity on the movable plate 43 reaches the given thrust that can push the movable plate 43 to rotate, the automatic discharge of the material in the storage cavity can be realized without opening the sealing door 40; thereby indirectly increasing the capacity of the storage cavity and further extending the cycle of opening the sealing door 40 for discharging materials. In actual implementation, in order to increase the given thrust required for the movable plate 43 to increase the capacity of the storage cavity, a spring assembly for driving the movable plate 43 to close can also be provided between the movable plate 43 and the fixed plate 45, or a counterweight can be detachably provided on the movable plate 43.
[0028] On the above basis, as Figure 2 shown, elastic sealing members 44 that elastically abut against the cleaning platform 60 are provided at the bottom of both side door panels and the outer door panel of the sealing door 40, which ensures the sealing performance between the bottom of the sealing door 40 and the cleaning platform 60 while enabling the sealing door 40 to be opened and closed stably.
[0029] Specifically, the elastic sealing member 44 is a rubber pad. Of course, in actual implementation, the elastic sealing member 44 can also be set as a telescopic baffle, and a spring for driving the telescopic baffle to be in an extended state is provided in the telescopic baffle.
[0030] On the above basis, as Figure 1 shown, in order to ensure that the sealing door 40 can be stably and automatically closed, an elastic reset member 50 for driving the sealing door 40 to reset to the closed state is installed on the funnel body 10.
[0031] On the above basis, as Figure 3 shown, a reinforcing rib 46 in the form of a grid frame structure is fixed on the outer door panel of the sealing door 40, which improves the strength of the sealing door 40 and ensures that the sealing door 40 can still maintain a long service life under the collision-driven opening mode between it and the automatic scraper cleaning device 30.
[0032] Of course, for those skilled in the art, the present utility model is not limited to the details of the above exemplary embodiments, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
[0033] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
