Description

Technical Field

[0001] This utility model relates to grate structures, and in particular to a hopper gate that can be automatically controlled. Background Technology

[0002] When incinerating combustibles such as garbage, incineration equipment with an internal grate structure is required. The grate is the core component of the incineration equipment, which is mainly used to support fuel (such as solid waste, biomass, etc.) and achieve efficient and complete combustion of fuel by controlling air flow, fuel movement and combustion rate.

[0003] In the operation of a grate furnace, the hopper device is of paramount importance. By controlling the gate at the bottom of the hopper, the material supply rate and bed thickness can be controlled, guiding the material evenly into the grate for combustion. This is a key structure for controlling the completeness of fuel combustion. Traditionally, the gate or hopper structure requires manual operation by workers using handwheels. This method has low automation, slow response, is cumbersome, time-consuming, and labor-intensive. Moreover, due to its slow response speed, the material bed is prone to fluctuations, leading to unstable combustion; it also poses certain safety hazards.

[0004] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0005] This invention aims to address the aforementioned shortcomings of existing technologies by proposing a hopper gate that features a simple structure, ingenious design, reasonable layout, rapid response, and precise and controllable lifting height.

[0006] The technical solution of this utility model is: a hopper gate capable of automated control, comprising a gate plate 1, characterized in that: two symmetrically distributed chains 2 are connected to the gate plate 1, the top ends of the chains 2 are connected to a retaining beam 3, and lifting drive mechanisms are provided at both ends of the retaining beam 3.

[0007] The lifting drive mechanism includes a lifting motor 5 fixedly mounted on the grate body 4. The output end of the lifting motor 5 is connected to the worm gear through a bevel gear transmission pair. The worm gear is rotated and supported on the grate body, and the worm gear and the worm 6 cooperate with each other. The top end of the worm 6 is fixedly connected to the bottom end face of the beam 3.

[0008] The grate body 4 is provided with longitudinally distributed guide rods 7, which are movably connected to the through holes opened at the ends of the girder 3.

[0009] Two guide rods 7 are movably connected to each end of the beam 3, and the tops of the two guide rods 7 are connected into a single structure by a U-shaped part 8.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] This type of hopper gate, capable of automated control, features a simple structure, ingenious design, and rational layout. Addressing the issue of traditional hopper gates requiring manual handwheel operation, it employs a unique structure. Utilizing two synchronously operating motors, the torque output of the motors is converted into the longitudinal linear motion of the worm gear through a worm gear transmission pair, achieving automated and precisely controllable lifting and lowering movements. It saves labor while achieving rapid response of the gate's actions, improving work efficiency. Furthermore, it allows for precise control of the gate's opening height, enabling precise control of the fuel thickness entering the combustion chamber. Simultaneously, because of its automated control, personnel are not required to approach the high-temperature combustion chamber, further eliminating safety hazards. Moreover, this hopper gate has a simple manufacturing process and low production cost. Therefore, it possesses numerous advantages, making it particularly suitable for widespread application in this field, with a very broad market prospect. Attached Figure Description

[0015] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 3 As shown: A hopper gate capable of automated control includes a gate plate 1, with two symmetrically distributed chains 2 connected to the gate plate 1. The top ends of the chains 2 are connected to a supporting beam 3, and lifting drive mechanisms are provided at both ends of the supporting beam 3.

[0016] The lifting drive mechanism includes a lifting motor 5 fixedly mounted on the grate body 4. The output end of the lifting motor 5 is connected to the worm gear through a bevel gear transmission pair. The worm gear is rotated and supported on the grate body, and the worm gear and the worm 6 cooperate with each other. The top end of the worm 6 is fixedly connected to the bottom end face of the beam 3.

[0017] The grate body 4 is provided with longitudinally distributed guide rods 7, which are movably connected to the through holes opened at the ends of the girder 3.

[0018] Two guide rods 7 are movably connected to each end of the beam 3, and the tops of the two guide rods 7 are connected into a single structure by a U-shaped part 8.

[0019] The working process of the hopper gate that can be automatically controlled according to this utility model embodiment is as follows: When it is necessary to adjust the height of the gate plate 1 to control the height of the material entering the combustion chamber, the control system issues an instruction and sends a signal to the lifting motor 5. The lifting motor 5 drives the worm wheel to rotate, and the worm 6 that cooperates with the worm wheel will make longitudinal linear motion accordingly. The lifting motors 5 in the two sets of lifting drive mechanisms act synchronously at the same time, thereby driving the beam 3 connected to the worm 6 to move longitudinally, and finally realizing the longitudinal movement of the gate plate 1.

[0020] During the above-mentioned movement, the longitudinal movement of the gate 1 can be precisely adjusted by controlling the rotation speed of the lifting motor 5, thereby achieving automated and precise control of the hopper gate.

[0021] When the beam 3 moves, it is connected to the guide rod 7 through the through hole, so the guide rod 7 can play a guiding role and ensure the smooth movement of the beam 3. At the same time, the two guide rods 7 in the same group are connected into a whole structure through the U-shaped part 8. This design can effectively improve the overall strength and rigidity of the guide rod 7, thereby ensuring the guiding effect.
