Description

Technical Field

[0001] This utility model relates to the field of gasifier technology, specifically a coal feeder for a gasifier. Background Technology

[0002] A gasifier is a reactor used to produce coal gas, water gas, and semi-water gas. In the prior art, a search revealed that, for example, Chinese patent (application number: 202121618963.X) discloses a coal feeder for a gasifier, comprising a base plate, a coal feeding mechanism and a support frame fixedly connected to the upper end of the base plate, a feeding hopper fixedly connected to the rear end of the support frame, a crushing mechanism fixedly connected to the upper end of the feeding hopper, a feeding hopper fixedly connected to the upper end of the crushing mechanism, a carrier plate fixedly connected to the lower end of the crushing mechanism, and an adjustment mechanism fixedly connected to the upper end of the carrier plate. The combination of these structures not only enables automated coal feeding but also allows for the crushing of coal according to different needs.

[0003] However, in actual use, we all know that during the process of coal being transported on the conveyor belt in the coal feeding mechanism, coal will fall from the outside of the support plate and hit people. Moreover, when the coal is crushed and transported, a lot of coal dust will be generated, which will be scattered everywhere and affect the environment. Therefore, improvements are needed. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a coal feeder for a gasifier, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A coal feeder for a gasifier includes a base, an inclined coal feeding mechanism mounted on the top of the base, a crushing mechanism mounted above the coal feeding end of the coal feeding mechanism, and a coal blocking mechanism mounted on the top of two symmetrically arranged support plates in the coal feeding mechanism. The coal blocking mechanism includes a blocking rod, the bottom of which is fixed to the top of the support plate, and a dust removal structure is installed between the two blocking rods.

[0007] Specifically, in this utility model, the dust removal structure includes several spray pipes that can be detachably installed between two baffles. Several spray holes are opened at the lowest point of the spray pipes. A cavity is opened inside one of the baffles. A water injection hole communicating with an external water pumping mechanism is opened at the upper end of the cavity. One end of the spray pipe is connected to the cavity.

[0008] To facilitate water flow, several water outlet holes are provided on the side of the baffle with a cavity. A connecting pipe is fixed outside the water outlet holes. One end of the spray pipe is connected to the connecting pipe and can be detachably connected, while the other end is detachably connected to another baffle.

[0009] To enable the nozzle to be detachable, an adjusting pipe is provided between the nozzle and the stop bar. Both the nozzle and the connecting pipe are threaded into the adjusting pipe. Several threaded grooves are provided on the inner side without the stop bar, and the other end of the nozzle is threaded into the threaded grooves.

[0010] Compared with the prior art, this utility model has the following advantages: the baffle can prevent coal from falling from both sides of the support plate and hitting people, and the water sprayed from the nozzle mixes with the coal ash and sinks, preventing environmental pollution. The structure is simple and more practical. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1-3As shown, this utility model provides a coal feeder for a gasifier, including a base 1. A coal feeding mechanism 2 is installed on the top of the base 1 at an incline. A crushing mechanism 3 is installed above the coal feeding end of the coal feeding mechanism 2. All of the above components are existing technologies. The crushing mechanism 3 can crush the coal and then drop it onto the conveyor belt of the coal feeding mechanism 2 for upward transport. The specific principle can be found in Chinese Patent (Application No.: 202121618963.X), which will not be repeated in this utility model. The top of the two symmetrically arranged support plates in the coal feeding mechanism 2 is equipped with a coal blocking mechanism. The coal blocking mechanism includes a baffle 4. The bottom of the baffle 4 is fixed to the top of the support plate, and a dust removal structure is installed between the two baffles 4.

[0021] like Figure 4-6 As shown, the dust removal structure of this utility model specifically includes several spray pipes 5 that can be detachably installed between two baffles 4. Several spray holes 5-1 are opened at the lowest point of the spray pipes 5. A cavity 4-1 is opened inside one of the baffles 4. A water injection hole 4-2 communicating with an external water pumping mechanism is opened at the upper end of the cavity 4-1. One end of the spray pipe 5 is connected to the cavity 4-1.

[0022] like Figure 6-7 As shown, in order to achieve water flow, several water outlet holes are opened on the side of the baffle 4 with cavity 4-1. A connecting pipe 6 is fixed outside the water outlet hole. One end of the spray pipe 5 is connected to the connecting pipe 6 and can be detachably connected, and the other end is detachably connected to another baffle 4.

[0023] like Figure 7 As shown, in order to make the nozzle 5 detachable, an adjusting pipe 7 is provided between the nozzle 5 and the stop bar 4. The nozzle 5 and the connecting pipe 6 are both threaded in the adjusting pipe 7. Several threaded grooves 4-3 are provided on the inner side where the stop bar 4 is not opened. The other end of the nozzle 5 is threaded in the threaded grooves 4-3.

[0024] The working principle of this utility model is described in detail below: When the coal feeding mechanism 2 transports coal, the baffle 4 can block the coal to prevent it from falling from the outside of the support plate and hitting people. At the same time, the external water pumping mechanism mainly includes a water pump. The water pump's suction pipe is connected to a water source, and the water outlet pipe is fixed outside the water injection hole 4-2. The water pump is started when the external power is connected, pumping water from the water source into the cavity 4-1 through the water injection hole 4-2, and then into the spray pipe 5 through the connecting pipe 6 and the regulating pipe 7, and then through... The nozzle 5-1 sprays water onto the coal, allowing the water to come into contact with the coal ash and settle, preventing coal ash from polluting the environment. When the nozzle 5 needs to be disassembled, rotate the adjusting pipe 7 towards the connecting pipe 6 until the adjusting pipe 7 is disengaged from one end of the nozzle 5. Then, the nozzle 5 can be rotated to remove the other end from the threaded groove 4-3. Conversely, it is also convenient to install the nozzle 5. Screw the nozzle 5 into the threaded groove 4-3 and rotate the adjusting pipe 7 towards the nozzle 5 until the adjusting pipe 7 is installed between the nozzle 5 and the connecting pipe 6.

[0025] Finally, the most significant contribution of this utility model is that the baffle 4 can prevent coal from falling from both sides of the support plate and hitting people, and the water sprayed from the nozzle 5-1 mixes with the coal ash and sinks, preventing environmental pollution. The structure is simple and more practical.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
