[0002] In the existing feeding device of the ash removal car, in order to avoid the loss of pressure during the loading process, a star-shaped unloader is usually used for loading operation. However, when the temperature of the external environment changes, the powder material such as cement is easy to stick, which causes the star-shaped unloader to be blocked and stopped, thereby affecting the unloading efficiency and the service life of the equipment, and frequent maintenance operations are required, which increases the operating cost. CONTENT OF THE UTILITY MODEL
[0003] The problem to be solved by the present application is that the existing feeding device for the ash removal car usually uses a star-shaped unloader to realize sealed loading, but the powder material sticks due to temperature changes, which causes the star-shaped unloader to be blocked, and frequent shutdown and maintenance are required.
[0004] To solve the above technical problems, the present application provides a feeding device for an ash removal car, which comprises a vertically arranged material cylinder, a material blocking assembly arranged at the central position of the inside of the material cylinder and used for on-off of the material cylinder by rotating opening and closing, an opening and closing assembly arranged at the bottom of the material cylinder and used for maintaining the negative pressure of the material cylinder during unloading operation by sliding opening and closing, and an openable and closable maintenance door arranged on the upper part of the sidewall of the material cylinder.
[0005] Since the feeding device of the present application is designed with the material blocking assembly and the opening and closing assembly, the on-off of the material cylinder can be controlled by the material blocking assembly which opens and closes by turning over, effectively avoiding the large pressure loss of the powder material during unloading, ensuring the effectiveness of material conveying, and the negative pressure state of the material cylinder can be maintained during unloading by the opening and closing assembly which opens and closes by sliding, reducing the sticking and blocking of the material, solving the problem of the existing feeding device for the ash removal car, which usually uses a star-shaped unloader to realize sealed loading, but the powder material sticks due to temperature changes, which causes the star-shaped unloader to be blocked, and frequent shutdown and maintenance are required.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. EMBODIMENT
[0015] The present application relates to a kind of ash car feed device, as shown in Figures 1-7 The feed device includes vertically arranged material cylinder 2, the inside of material cylinder 2 is arranged in central position, and material blocking assembly 3 for the on-off of material cylinder 2 is arranged in a rotary opening and closing mode, the bottom of material cylinder 2 is arranged with opening and closing assembly 1 for maintaining the negative pressure of material cylinder 2 in a sliding opening and closing mode, in addition, the upper part of the sidewall of material cylinder 2 is also arranged with openable and closable maintenance door 4, to facilitate the daily maintenance and overhaul of equipment, in the use process, powdery material enters from the top of material cylinder 2, and the quantitative discharge of material is realized by the control of material blocking assembly 3, and opening and closing assembly 1 maintains the negative pressure state of material cylinder 2, to prevent material from sticking and blocking, when the equipment needs to be overhauled, the maintenance and overhaul operation can be conveniently carried out by opening maintenance door 4, by the flip opening and closing design of material blocking assembly 3 and the sliding opening and closing design of opening and closing assembly 1, the problem that powdery material is easily stuck to cause equipment blockage when temperature changes is effectively solved, the discharge efficiency is improved, the maintenance frequency is reduced, and good practicability and wide application prospect are obtained.
[0016] The material blocking assembly 3 mainly consists of a first motor 7, a first shaft 8, a material blocking plate 9 and a rubber ring 10. The first motor 7 is arranged outside the barrel 2 and serves as a power source to drive the first shaft 8 to rotate. The first motor 7 is connected with the first shaft 8 through a suitable transmission mechanism (such as a shaft coupling or a spline) to ensure smooth and efficient rotation. The first shaft 8 is horizontally arranged inside the barrel 2 and rotates through a bearing installed on the side wall of the barrel 2 to provide stable support for the first shaft 8 and allow it to rotate freely. The material blocking plate 9 is arranged on the upper part of the first shaft 8 and connected with the first shaft 8 through bolts. This connection not only ensures the stability of the material blocking plate 9 but also facilitates its disassembly and replacement when needed. The shape and size of the material blocking plate 9 are designed according to the internal structure of the barrel 2 to ensure that it can effectively control the on-off of the material unloading. The rubber ring 10 is riveted at the edge of the material blocking plate 9 to improve the airtightness between the material blocking plate 9 and the inner wall of the barrel 2. The rubber ring 10 is made of wear-resistant and corrosion-resistant materials to ensure good sealing effect during long-term use.
[0017] Working principle: When the first motor 7 starts, it drives the first shaft 8 to rotate. Since the material blocking plate 9 is connected with the first shaft 8 through bolts, it also rotates with the first shaft 8. During rotation, the material blocking plate 9 controls the on-off of the barrel 2 unloading according to its position and angle changes. Specifically, when the material blocking plate 9 rotates to a certain position, it blocks the material from falling from the upper part of the barrel 2, thereby stopping unloading. When the material blocking plate 9 rotates to other positions, it allows the material to pass, thereby enabling unloading. This method of controlling the on-off of unloading by rotating the material blocking plate 9 is simple and effective, which can ensure that the material does not lose pressure significantly during unloading, thereby preventing material failure. In addition, since the rubber ring 10 is riveted at the edge of the material blocking plate 9, it can maintain good airtightness between the material blocking plate 9 and the inner wall of the barrel 2 during rotation. This airtightness not only helps to prevent material leakage and flying during unloading, but also reduces the contact between the material and the air, thereby reducing the risk of material sticking due to temperature changes.
[0018] The opening and closing assembly 1 comprises a frame 12, a supporting wheel 16, a rail plate 13, a second motor 11, a second shaft 17, a gear 14 and a rack 15. The frame 12 is designed in the shape of a cuboid and arranged at the bottom of the barrel 2. The frame 12 is internally designed with a sliding rail groove to allow the rail plate 13 to slide therein, thereby achieving the opening and closing control of the discharge port of the barrel 2. In order to ensure the stability of the rail plate 13 during the sliding process and prevent it from warping, a plurality of supporting wheels 16 are symmetrically arranged inside the frame 12. These supporting wheels 16 not only support the rail plate 13, but also effectively prevent the rail plate 13 from deviating or warping during the movement, ensuring the accurate opening and closing of the discharge port. The outer side of the frame 12 is provided with the second motor 11, which provides driving force for the entire opening and closing assembly 1. The second motor 11 is connected to the second shaft 17 through a transmission mechanism, and the second shaft 17 is connected to the frame 12 through a bearing, ensuring the stability and accuracy of rotation. The middle line position of one side of the rail plate 13 is provided with the rack 15, and the upper part of the second shaft 17 is provided with the gear 14 engaged with the rack 15. When the second motor 11 starts, it drives the second shaft 17 to rotate, which in turn drives the gear 14 to rotate. Since the gear 14 is engaged with the rack 15 on the rail plate 13, the rotation of the gear 14 will push the rail plate 13 to slide inside the frame 12, thereby achieving the opening or closing of the discharge port. Through this design, the opening and closing assembly 1 can accurately and quickly control the discharging operation of the barrel 2 and ensure that the negative pressure state of the barrel 2 is maintained during the discharging process, which not only improves the discharging efficiency, but also effectively prevents material leakage and the entry of external air, further ensuring the safety and stability of the discharging process.
[0019] Working principle: when the discharge port needs to be opened, the second motor 11 starts to drive the second shaft 17 to rotate, which in turn drives the gear 14 on the second shaft 17 to rotate. Since the gear 14 is engaged with the rack 15 on the rail plate 13, the rotation of the gear 14 will push the rack 15, which in turn drives the rail plate 13 to slide to one side inside the frame 12, gradually opening the discharge port. During the sliding process of the rail plate 13, the supporting wheels 16 play a supporting and guiding role, ensuring that the rail plate 13 can move smoothly and accurately. When the discharging is completed, the second motor 11 is reversed to drive the gear 14 to rotate in the opposite direction, thereby driving the rail plate 13 to slide to the other side, closing the discharge port. Through this design, the opening and closing assembly 1 can accurately control the opening and closing of the discharge port of the barrel 2 and ensure that the negative pressure state of the barrel 2 is maintained during the discharging process, which not only improves the efficiency and stability of the discharging, but also effectively prevents material leakage and the entry of external air, thereby ensuring the safety and reliability of the entire feeding device.
[0020] If necessary, the shade assembly 3 and the opening and closing assembly 1 can be additionally provided with a travel switch 5 and a stopper 6, and the opening and closing angle of the shade assembly 3 and the sliding opening and closing distance of the opening and closing assembly 1 are controlled through the travel switch 5.
