Description

Technical Field

[0001] This utility model relates to the field of coal feeder technology, and in particular to a coal feeder coal quantity control component. Background Technology

[0002] A coal feeder is a mechanical device used to uniformly and continuously transport coal to a boiler or other combustion equipment. It plays an important role in thermal power plants, industrial boiler rooms and related thermal energy projects, ensuring the stability and efficiency of fuel supply.

[0003] The existing announcement number is CN219640294U, entitled "A Coal Feeder Outlet Flow Adjustment Device," which includes a pusher hopper and adjustment components symmetrically installed on both sides of the pusher hopper outlet, forming a clamping shape for adjusting the outlet flow. The adjustment components include a first folding plate and a second folding plate. One side of the first folding plate is vertically rotatably mounted on the pusher hopper, and the other side of the first folding plate is rotatably connected to one side of the second folding plate. The other side of the second folding plate is slidably mounted on a guide rail, which is fixedly mounted on the side wall of the pusher hopper. The first and second folding plates form a raised structure, creating a flow adjustment device to control the size of the coal feeder outlet flow. By using two folding plates installed on both sides of the coal feeder trough, the angle of the folding plates is adjusted to control the coal outlet space. The angle is adjusted according to the moisture content of the raw coal to achieve a balanced coal outlet flow.

[0004] However, the aforementioned coal feeder uses two symmetrically arranged folding plates at the pusher hopper to block the coal from falling and control the coal falling rate. However, the coal is blocked by the two folding plates at the pusher hopper, which reduces the coal falling rate and causes the coal to become blocked at the two folding plates, thus affecting the coal falling rate. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a coal feeder coal quantity control component.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a coal feeder coal quantity control component, including a transport component and a control component. The transport component includes a transport frame, in which a transport roller is horizontally and symmetrically rotatably connected, and a transport belt is tensioned and connected to the transport roller. A transport motor is horizontally fixed at one end of the transport frame, and the output end of the transport motor is fixed at the end of the transport roller. The control component includes a control frame, which is located on the lower side of the tail end of the transport frame. Multiple dispersing strips are horizontally arranged inside the control frame, and a receiving frame is inclinedly fixed on the top surface of the control frame. A movable trough plate is horizontally arranged inside the control frame on the lower side of the multiple dispersing strips, and a sliding rod is horizontally fixed at one end of the movable trough plate. The sliding rod is horizontally slidably assembled on one side end face of the control frame. A hydraulic rod is horizontally fixed on the outer wall of the control frame, and the output end of the hydraulic rod is fixed on the end face of the movable trough plate.

[0007] As a preferred embodiment, a sliding frame is vertically fixed on the top surface of the transport frame near the tail end, and a hopper is vertically fixed on the top surface of the transport frame near the head end.

[0008] As a preferred embodiment, a screw hole slider is vertically slidably assembled on the slide frame, and a scraper is vertically fixed on one end face of the screw hole slider.

[0009] As a preferred embodiment, a screw is vertically rotatably connected to the slide frame, and the screw is threaded through the slider in the screw hole.

[0010] As a preferred embodiment, a perforated strip is vertically fixed on one side of the tail end of the transport frame, and a rod seat is fixed on one end face of the control frame.

[0011] As a preferred embodiment, the rod seat is vertically slidably inserted into the hole strip, and springs are vertically fixed on both the upper and lower sides of the rod seat, with the other end of the springs fixed to the hole strip.

[0012] As a preferred option, a vibration motor is horizontally fixed on the top surface of the rod base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the coal falls into the hopper and onto the conveyor belt of the conveyor frame. The conveyor motor is started to drive the conveyor roller to rotate, which drives the conveyor belt to run and moves the coal towards the tail end. The coal falls into the control frame of the control component. Then, according to the needs of the coal falling, the hydraulic rod on the control frame is activated to push the moving trough plate to move horizontally in the control frame. By adjusting the vertical gap between the dispersion bar and the moving trough plate, the size of the gap of the coal falling is controlled. In turn, by controlling the size of the interval of the coal falling, the falling rate of the coal is controlled. Attached Figure Description

[0026] like Figures 1 to 5 As shown, a coal feeder coal quantity control component includes a transport component 1 and a control component 2. The transport component 1 includes a transport frame 11, in which transport rollers 12 are horizontally and symmetrically rotatably connected, and a transport belt 13 is tensioned and connected to the transport rollers 12. A transport motor 14 is horizontally fixed at one end of the transport frame 11, and the output end of the transport motor 14 is fixed at the end of the transport rollers 12. The control component 2 includes a control frame 21, which is located on the lower side of the tail end of the transport frame 11. Multiple dispersing bars 23 are horizontally arranged inside the control frame 21, and a receiving frame 22 is inclinedly fixed on the top surface of the control frame 21. A movable trough plate 25 is horizontally arranged inside the control frame 21 below the multiple dispersing bars 23, and a sliding rod 26 is horizontally fixed at one end of the movable trough plate 25, and the sliding rod 26 slides horizontally. Assembled on one side end face of control frame 21, hydraulic rod 24 is horizontally fixed on the outer wall of control frame 21, and the output end of hydraulic rod 24 is fixed on the end face of moving trough plate 25. In use, coal is dropped into hopper 15 and falls onto conveyor belt 13 of conveyor frame 11. Conveyor motor 14 is started to drive conveyor roller 12 to rotate, drive conveyor belt 13 to run, and drive coal to move towards the tail end. Coal falls into control frame 21 of control component 2. Then, according to the coal falling requirements, hydraulic rod 24 on control frame 21 is started to push moving trough plate 25 to move horizontally in control frame 21. By adjusting the vertical gap between dispersion bar 23 and moving trough plate 25, the size of the gap of coal falling is controlled. In turn, by controlling the size of the interval of coal falling, the falling rate of coal is controlled.

[0027] In one embodiment, such as Figure 2 and 3 As shown, a sliding frame 16 is vertically fixed on the top surface of the conveyor frame 11 near the tail end, and a hopper 15 is vertically fixed on the top surface of the conveyor frame 11 near the head end. A screw hole slider 18 is vertically slidably assembled on the sliding frame 16, and a scraper 181 is vertically fixed on one end face of the screw hole slider 18. A screw rod 17 is vertically rotatably connected in the sliding frame 16, and the screw rod 17 and the screw hole slider 18 are threaded through each other. During use, the thickness of the coal transported on the conveyor belt 13 is controlled. By rotating the screw rod 17 on the sliding frame 16, the screw hole slider 18 is driven to move vertically, and then the scraper 181 is driven to fall vertically, controlling the gap between the conveyor belt 13 and the scraper 181, scraping off the coal on the conveyor belt 13, and controlling the thickness of the coal transport.

[0028] In one embodiment, such as Figure 2 and 3As shown, a perforated strip 19 is vertically fixed to one side of the tail end of the transport frame 11.

Springs 28 are vertically fixed to both the upper and lower sides of the rod seat 27. The other end of the springs 28 is fixed to the perforated strip 19. A vibration motor 29 is horizontally fixed to the top surface of the rod seat 27. In order to accelerate the falling speed of coal in the control frame 21, the vibration motor 29 is started to drive the rod seat 27 to slide vertically on the perforated strip 19, compressing the springs 28 to deform, and causing the control frame 21 to vibrate vertically on the transport frame 11, thereby accelerating the falling speed of coal in the control frame 21.

[0029] In this embodiment, during use, coal is dropped into the hopper 15 and falls onto the conveyor belt 13 of the conveyor frame 11. The conveyor motor 14 is started to drive the conveyor roller 12 to rotate, which drives the conveyor belt 13 to run and move the coal towards the tail end.

By adjusting the vertical gap between the dispersion bar 23 and the moving trough plate 25, the size of the gap of coal falling is controlled, and thus the size of the interval of coal falling is controlled.

[0030] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
