Description

Technical Field

[0001] The utility model relates to the technical field of garbage incineration equipment, in particular to a grate material layer control device for garbage incineration. Background Art

[0002] Waste-to-energy technology is maturing, making significant contributions to the environmental protection industry. Currently, most incinerators utilize reciprocating grates, resulting in relatively rough combustion. This leads to various common combustion issues during the incineration process. High moisture content in waste, particularly in summer, can reach up to 38% leachate. High moisture content in waste is prone to material slippage, which typically occurs when the pusher retreats. Gravity forces the waste to quickly fill the space left by the retreating trolley, creating a powerful impact that can cause significant material slippage, sometimes even bypassing the drying and combustion stages and sliding directly into the slag pit.

[0003] Uneven material layers will cause uneven primary air distribution. Where the material layer is thin, the primary air resistance is small, the combustion intensity is greater, the garbage is burned out first, and the grate temperature is relatively high. Where the material layer is thick, the primary air cannot penetrate effectively, the combustion intensity is weak, and the garbage cannot be burned out within the same time, which brings great hidden dangers to the operation of the incinerator, resulting in uneven combustion of the fire bed, raw materials, incomplete burning, large fluctuations in steam parameters, and reduced power generation per ton. Utility Model Content

[0004] The purpose of the utility model is to propose a control device for the grate charge layer of a garbage incineration grate, which can effectively control the discharge amount of the pushing grate in one movement by adding a baffle plate on the upper part of the discharge port and lowering the height of the discharge port, and install a distribution plate at the front part of the pusher, select the optimal spacing, and gradually increase the spacing from the middle to the two sides. Through the above transformation, the purpose of distributing garbage can be effectively achieved, and the thickness of the material layer can be more evenly distributed, thereby solving the problems of uneven combustion of the fire bed, raw materials, incomplete burning, large fluctuations in steam parameters, and reduced power generation per ton in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for controlling the grate charge layer of a waste incineration grate, which is used in a waste incinerator, and the waste incinerator includes a feeding port, a pusher, and a discharging port, and is characterized in that: a plurality of baffle plates are arranged at the lower part of the feeding port, and a plurality of distribution plates are arranged at the front section of the pusher; the baffle plates are arc-shaped plates, which are bent toward the pushing direction of the pusher; the distribution plates are isosceles triangle plates with obtuse vertex angles, and the equilateral sides are fixed to the pusher, and multiple distribution plates are arranged symmetrically, and the spacing between adjacent distribution plates gradually increases from the middle to the two sides.

[0006] Furthermore, covering plates are fixed to the edges of the plurality of material blocking plates.

[0007] Furthermore, a material unloading auxiliary component is provided at the discharge port. The material unloading auxiliary component includes a material unloading auxiliary box, a connecting block, a spring connecting piece, a connecting arc plate, a placement cylinder, an internal pressure detection sensor, an elastic connecting cushion layer and an inclined primary unloading plate. The material unloading auxiliary box is fixedly connected to the right side of the adjustment pusher platform, the connecting block is fixedly connected to the bottom of the material unloading auxiliary box, the connecting arc plate is fixedly connected to the bottom of the connecting block, the inclined primary unloading plate is connected to the right side of the material unloading auxiliary box, and the spring connecting piece is fixedly connected to the bottom of the inclined primary unloading plate.

[0008] Furthermore, the number of the spring connectors is six, and the six spring connectors are divided into two groups, with the number of the spring connectors in each group being three.

[0009] Furthermore, a connecting V-shaped plate is fixedly connected to the top of the connecting arc plate, and the placement tube is fixedly connected to the inner center position of the connecting V-shaped plate.

[0013] Furthermore, the three spring connectors are arranged in an arc shape at the top of the connecting arc plate close to the front side and close to the back side.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The device for controlling the material layer of a waste incineration grate is designed to effectively control the material discharge amount of the push grate during one movement by installing a baffle plate on the upper part of the material discharge port to lower the height of the material discharge port. A distribution plate is installed at the front part of the pusher, and the optimal spacing is selected and gradually increased from the middle to the two sides.

[0024] Specifically, the waste incinerator body is provided with an opening for feeding waste, namely, a feeding port A, and a pushing platform B2 is provided below the feeding port A. The pushing platform B2 is specifically a plate fixed on the waste incinerator body. A pusher B is provided on the pushing platform B2. The pusher B is generally actuated by hydraulic pressure to push the waste entering from the feeding port A to the discharging port C and into the combustion chamber.

[0025] A number of baffle plates A1 are provided at the lower part of the feeding port A, and a number of distribution plates B1 are provided at the front section of the pusher B; the baffle plates A1 are arc-shaped plates, which are bent toward the pushing direction of the pusher B; the distribution plates B1 are isosceles triangle plates with obtuse vertex angles, and the equilateral sides are fixed to the pusher B. Multiple distribution plates B1 are arranged symmetrically, and the spacing between adjacent distribution plates B1 gradually increases from the middle to the two sides.

[0026] A covering plate A11 is fixed to the edge of the plurality of baffle plates A1 to form an arc surface on the outside of the baffle plates A1. To improve durability, refractory fillers are placed inside the covering plate A11.

[0027] The above modifications effectively achieve the goal of waste distribution, ensuring a more evenly distributed material layer. The height of the opening between the pusher platform B2 and the upper portion of the feed port A can be adjusted by setting the baffle plate A1. A distribution plate B1 with a predetermined inclination angle and height is designed at the front end of the pusher. These distribution plates are welded directly to the feed platform, with the spacing between them gradually increasing from the center to the sides. The distribution plates are made of highly wear-resistant NM500 material. The pusher speed and stroke are adjusted according to combustion conditions to achieve optimal results.

[0028] As attached Figure 2-3 As shown, the pushing platform B2 at the discharge port C is provided with a material unloading auxiliary component 2.

[0029] The blanking auxiliary component 2 includes a blanking auxiliary box 201, a connecting block 202, a spring connector 203, a connecting arc plate 204, a placement tube 205, an internal pressure detection sensor 206, an elastic connecting pad 207 and an inclined primary blanking plate 208.
