Description

Technical Field

[0001] This invention relates to the field of grate cooler technology, specifically to a grate cooler capable of measuring and controlling the thickness distribution of the material layer. Background Technology

[0002] The grate cooler is a crucial piece of equipment in the clinker calcination system of a cement plant. Its main functions are to cool and transport cement clinker; it also provides hot air for the rotary kiln and precalciner, and is a key component in heat recovery within the calcination system. The grate cooler is a type of rapid cooling cooler. After entering the cooler from the kiln, the clinker forms a layer of a certain thickness on the grate. Cold air is blown in and passes through the moving material layer on the grate in a perpendicular direction, rapidly cooling the clinker from 1300-1400℃ to below 100℃ within minutes.

[0003] Traditional grate coolers are classified into three types: rotary, vibrating, and push-type. However, since the first two types have been phased out, the push-type grate cooler has become the main type of cement clinker cooler used in conjunction with precalciner kilns. The grate is the main component of the cooler, and the push-type grate consists of rows of fixed and movable grate plates arranged at intervals.

[0004] Currently, if the material layer is too thick, the clinker stays in the grate cooler for a longer time, but the cooling air has difficulty penetrating the thick material layer, resulting in insufficient cooling of the clinker. This will cause the clinker temperature to be too high and enter the subsequent conveying and storage stages, which may cause problems such as gypsum dehydration and false setting of cement, affecting the quality stability of cement. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a grate cooler capable of measuring and controlling the thickness distribution of the material layer, thus solving the problem of improper thickness control.

A thickness control component is provided. Uniformly distributed laser rangefinders are fixedly connected to the top of the inner walls of the cooling box and the discharge box. Uniformly distributed sliding grooves are formed on the outer walls of the cooling box and the discharge box. Second protective covers are fixedly connected to both ends of one side of the outer walls of the cooling box and the discharge box. A lead screw motor is fixedly connected to the top of the second protective cover. A nut pair is threaded through and slidably connected to the output end of the lead screw motor and the second protective cover. A rotating rod is provided at one end of each nut pair. A first protective cover is fixedly connected to both ends of the other side of the outer walls of the cooling box and the discharge box. A push rod motor is fixedly connected to one top and one bottom side of the first protective cover. A fixing block is fixedly connected to the output end of the push rod motor. A third servo motor is threaded through and provided at one end of the fixing block.

[0007] Preferably, the material distribution component includes a baffle that is slidably connected to the inner wall of the feeding hopper. Both ends of the baffle are fixedly connected to racks. A first servo motor is fixedly connected to one side of the outer wall of the feeding hopper. A gear is fixedly connected to the output end of the first servo motor, and the gear meshes with the rack.

[0008] Preferably, the thickness control component includes a first fixed plate and an eccentric wheel. The first fixed plate is fixedly connected to the bottom of one side of the slide rod, and the eccentric wheel is fixedly connected to the bottom of the other side of the slide rod. The bottom of the first fixed plate is fixedly connected with a uniformly distributed first top rod.

[0009] Preferably, a second fixing plate is fixedly connected to the bottom of the eccentric wheel, and a second top rod is fixedly connected to the middle of the bottom of the second fixing plate.

[0010] Preferably, a base is fixedly connected to the bottom of the support.

[0011] Preferably, a protective plate is fixedly connected to one side of the top of the feeding funnel, a feeding plate is fixedly connected to the bottom of the inner wall of the feeding funnel, and an anti-stacking block is rotatably connected to the output end of the hydraulic cylinder, and the anti-stacking block is slidably connected to the top of the feeding plate.

[0014] This invention provides a grate cooler capable of measuring and controlling the material layer thickness distribution. It offers the following advantages:

[0015] 1. This invention uses a laser rangefinder to detect the thickness of the material on the grate. When the material level is too high or too low, the grate rises more significantly in areas with thicker material layers and less significantly or remains unchanged in areas with thinner material layers. By using push rod motors and lead screw motors to drive the fixed blocks and nut pairs to move up and down, the grate moves up and down, thereby adjusting the rise of the grate. In conjunction with the thickness control component, the clinker is evenly distributed to different parts of the grate cooler, avoiding the concentration of clinker in a certain area, which would result in uneven material layer thickness.

[0016] 2. The present invention controls the feeding speed by turning on the first servo motor, which in turn drives the gear to rotate, thereby moving the baffle up and down through the rack. This ensures that the clinker is evenly distributed on the grate, avoiding local accumulation and ensuring the stability of raw material feeding. Attached Figure Description

The first fixed plate 20 is fixedly connected to the bottom of one side slide bar 18, and the eccentric wheel 22 is fixedly connected to the bottom of the other side slide bar 18.

[0032] A feeding hopper 5 is fixedly connected to the top of the feeding box 3. A protective plate 10 is fixedly connected to one side of the top of the feeding hopper 5.

[0033] The inner wall of the cooling box 8 is provided with evenly distributed grate beds 15, and one end of the grate beds 15 is fixedly connected to the output end of the third servo motor 30.
