Technical Field
[0001] This utility model relates to the field of material feeding technology, and in particular to an automatic material feeding system for a hopper. Background Technology
[0002] During the purification of electrolytic flue gas, the material collected by the dust removal system is fed into the hopper below the dust collector.
[0003] During long-term operation, existing dust collectors often experience the formation of hard, lumpy clumps that detach from the hopper sidewalls or filter bags. These clumps are difficult to break. If these lumps fall into the lower conveying chute, they can reduce the material conveying speed or even cause blockages, thus affecting the material discharge rate and leading to uneven discharge. Furthermore, the discharge process requires regular manual cleaning of the lumpy material, which generates dust and causes environmental pollution. Utility Model Content

[0017] Compared with the prior art, the automatic hopper feeding system provided by this utility model has the following advantages:
[0018] 1. This utility model device is equipped with two feeding pipelines. One of the feeding pipelines is equipped with a control valve, which can realize quantitative feeding of materials, so as not to fluctuate the amount of material or cause uneven feeding. When there is little material in the hopper, the control valve is closed to prevent the negative pressure in the hopper from being transmitted to the chute, which would cause the material in the chute to be sucked away by the negative pressure of the system and cause secondary losses.

[0019] 2. This utility model device is equipped with a filtering and crushing component. The amount of material can be adjusted by manual valves or by the size of the filtering and crushing component and the speed of the reducer. The crushing of the material is completed inside the system, eliminating the need for regular manual cleaning and saving labor costs. Crushing is also carried out during the material feeding process, reducing dust and protecting the environment. Attached Figure Description

[0024] like Figure 1 As shown in the figure, an automatic hopper material control and feeding system provided by this utility model includes: a filter screen 1, a feeding pipe 2, a conveying chute 4, a filter crushing assembly 5, a manual butterfly valve 6, and a feeder 7.
[0025] The feeding pipe 2 is installed on the side wall of the dust collector's feeding hopper 8; a filter screen 1 is installed between the feeding pipe 2 and the dust collector's feeding hopper 8; the filter screen is installed inside the dust collector's feeding hopper 8 and can separate powdery materials from lumpy materials; the diameter of the filter screen 1 is smaller than the diameter of the lumpy materials. The filter screen 1 is available in various sizes and can be selected and replaced according to the size of the material.
[0026] The lower end of the feeding pipe 2 is provided with a conveying chute 4; a material control valve 3 is provided between the feeding pipe 2 and the conveying chute 4. The material control valve 3 can use the internal counterweight structure to feed material quantitatively. The internal valve plate is equivalent to a loading device. When the material on the valve plate accumulates to a weight greater than that of the counterweight, the valve opens.
[0027] The control valve 3 includes: a first reducing flange 301, a second reducing flange 305, a counterweight 304, and a valve plate 306; the first reducing flange 301 is fitted inside the second reducing flange 305; the flange of the first reducing flange 301 is secured to the flange of the second reducing flange 305; there is a gap between the inner wall of the second reducing flange 305 and the outer wall of the first reducing flange 301, and there is a certain distance between the lower end of the first reducing flange 301 and the inner bottom of the second reducing flange 305 to facilitate the up-and-down movement of the counterweight 304. The distance between the lower end of the first reducing flange 301 and the inner bottom of the second reducing flange 305 is greater than or equal to the length of the counterweight 304.
[0028] A valve plate 306 is movably installed at the lower outlet of the first reducing flange 301; the diameter of the valve plate 306 is larger than the diameter of the outlet of the first reducing flange 301, which can achieve sealing of the outlet of the first reducing flange.
[0029] Two connecting blocks 307 are fixedly installed on the lower outer wall of the first reducing flange 301; a connecting shaft 302 passes between the lower parts of the two connecting blocks 307; two stiffening plates 308 are movably installed on the connecting shaft 302 between the two connecting blocks 307; the stiffening plates 308 are located on a valve plate 306 at one end of the bottom of the first reducing flange, and the upper end face of the valve plate 306 can contact the lower outlet of the first reducing flange, the diameter of the valve plate 306 is larger than the diameter of the outlet of the first reducing flange 301; a counterweight connecting shaft 303 is movably installed between the other ends of the two stiffening plates 308; a counterweight 304 is movably installed on the counterweight connecting shaft 303; the weight of the counterweight 304 is greater than the weight of the valve plate 306; the stiffening plates 308 do not interfere with the connecting blocks. Nuts are threaded to both ends of the connecting shaft 302 and the counterweight connecting shaft 303.
[0030] The upper flange of the first reducing flange 301 is connected to the discharge end of the feed pipe 2. When there is no material on the valve plate 306, the valve plate is sealed to the outlet of the first reducing flange. When the material accumulates to a weight greater than that of the counterweight, the counterweight moves upward under the action of its weight. At this time, one end of the stiffener 308 drives the valve plate to move downward, the valve opens, and the material falls into the second reducing flange 305. Then, it enters the conveying chute 4 through the lower outlet of the second reducing flange 305. After the material on the valve plate falls, the weight of the counterweight 304 is greater than that of the valve plate, so it moves downward, driving the end of the stiffener to move downward. Thus, the other end of the stiffener moves upward, driving the valve plate to seal the lower outlet of the first reducing flange.
[0031] The dust collector's discharge hopper 8 is equipped with a feeder 7 at its discharge port; the feeder 7 is equipped with a filter and crushing assembly 5 at its discharge port, which can crush block materials; the discharge port of the filter and crushing assembly 5 is connected to the conveying chute 4; a manual butterfly valve 6 is installed between the feeder 7 and the filter and crushing assembly 5.
[0032] A ventilated plate is provided in the middle of the feeder 7; multiple ventilated holes are provided on the ventilated plate; the diameter of the ventilated holes is larger than the diameter of the lumpy material. The upper part of the ventilated plate is a material chamber; the lower part of the ventilated plate is an air chamber; a fan 9 is connected to the outside of the air chamber. The material falling from the dust collector's feed hopper includes powdery material and lumpy material. After ventilation in the air chamber, the heavier lumpy material can be stored at the bottom, while the lighter powdery material floats on top of the lumpy material.
[0033] The filtering and crushing assembly 5 includes: a motor, a reducer, a housing, and a screen; the lower end of the feeder 7 is connected to the upper end of the housing; a motor is installed on one side of the housing; the output end of the motor is connected to the reducer; the rotating shaft of the reducer extends downward into the housing; a screen is installed at the end of the rotating shaft; crushing nails are installed on both the screen and the inner wall of the housing.
[0034] Working principle of this utility model:
[0035] Before the system starts operating, the blower 9 is turned on first. As material falls into the dust collector's discharge hopper 8, it gradually increases in volume. After passing through the filter screen 1, the powdery material enters the discharge pipe 2 and falls into the control valve 3. As the material accumulates, the valve plate in the control valve 3 opens, and the powdery material falls into the conveying chute 4 for downstream transport. Meanwhile, another batch of material, under the air separation of the feeder 7, falls through the manual butterfly valve 6 into the filter crushing assembly 5. The crushed powdery material also falls into the conveying chute 4 for downstream transport.
[0036] This allows powdery and lumpy materials to be crushed and conveyed within the system without the need for additional manual cleaning, preventing dust from flying and protecting the environment.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
