AI Technical Summary
When the lime kiln is running for a long time or the powder increases, the silicon elements in the powder form ring blocks, affecting lime roasting, causing the ring blocks to fall off and block the cooler, causing the high-quality finished lime blocks to be unable to be recycled, and thus affecting the yield.
A collection device including a rotary kiln, a cooler, a large-block door, a slip pipe, a separation unit and a recycling hopper were designed. The ring block and a small lime block were separated by the grille in the slip pipe, and they were transported to the Large block hoppers and recycling hoppers are collected separately by pulverization and air-cooling.
The separation and collection of the accumulated ring blocks and lime blocks is achieved, avoiding yield losses and preventing the accumulated ring blocks from blocking the cooler, ensuring the cooling effect and recycling of finished lime blocks.

Abstract
Description
Technical Field
[0001] The utility model relates to a collecting device capable of separating ring blocks and lime from a rotary kiln, belonging to the rotary kiln roasting technology. Background Art
[0002] When the lime kiln is in operation for a long time or the powder in the kiln increases, the silicon element in the powder will form ring blocks in the kiln, affecting the normal roasting of lime. Under the influence of the outside world, some ring blocks fall off and block the cooler feed grid, affecting the cooling effect. When the ring blocks are discharged through the large material door, a large number of high-quality finished lime blocks will be taken out, resulting in the inability to recycle the high-quality finished lime blocks, causing production losses. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a collection device capable of separating rotary kiln ring blocks and lime in view of the above-mentioned prior art, so as to separate the ring blocks from the lime blocks and collect them separately, thereby avoiding production loss and clogging the cooler with the ring blocks.
[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a collection device capable of separating rotary kiln ring blocks and lime, comprising a rotary kiln, a cooler is provided at the bottom of the rotary kiln, a large block material door is provided on the side of the rotary kiln, the large block material door is connected to a chute, the chute outlet is connected to a large block hopper, a separation unit is provided at the bottom of the chute, the separation unit outlet is connected to a recovery hopper, a lime block conveying belt is provided below the recovery hopper, and the recovery hopper outlet faces the lime block conveying belt.
[0005] The recovery hopper outlet is provided with a rod valve.
[0006] The separation unit comprises a separation port, which is opened at the bottom of the slide pipe and on which a grid is laid.
[0007] The bulk material hopper outlet is provided with a discharge valve.
[0008] Compared with the prior art, the utility model has the advantages of: a collection device capable of separating rotary kiln ring blocks and lime, capable of separating the ring blocks from small lime blocks and collecting them separately, thus avoiding production losses and clogging the cooler with the ring blocks. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a schematic diagram of a collection device capable of separating rotary kiln ring blocks and lime according to an embodiment of the utility model;
[0010] In the figure, 1 is a rotary kiln, 2 is a cooler, 3 is a lime block conveyor belt, 4 is a large block material door, 5 is a chute, 6 is a large block hopper, 7 is a recovery hopper, 8 is a grid, and 9 is a bar valve. DETAILED DESCRIPTION
[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] like Figure 1 As shown, a collection device for separating rotary kiln ring blocks and lime in this embodiment includes a rotary kiln 1, and a cooler 2 is provided at the bottom of the rotary kiln 1. A large block material door 4 is provided on the side of the rotary kiln 1, and a chute 5 is connected to the large block material door 4, so that the chute is connected to the inner cavity of the rotary kiln. The outlet of the chute 5 is connected to a large block hopper 6, and a separation port is provided at the bottom of the middle section of the chute 5, and a grille 8 is laid on the separation port. A recovery hopper 7 is provided below the chute 5, and the separation port is connected to the recovery hopper 7. A lime block conveying belt 3 is provided at the bottom of the recovery hopper 7, and the outlet of the recovery hopper 7 faces the lime block conveying belt 3. A jaw discharge valve is provided at the outlet of the large block hopper 6, and a rod valve 9 is provided at the outlet of the recovery hopper 7.
[0013] A separation port is opened in the middle section of the chute and a 100*100 grid is set at the separation port. The ring blocks and small lime blocks in the rotary kiln flow into the chute. The grid separates the ring blocks and small lime blocks. The ring blocks slide into the large block hopper and are powdered by spraying and absorbing moisture. The jaw discharge valve is opened to discharge the ring blocks in the large block hopper to a loading truck or car and transported to the raw material system for recycling. The small lime blocks enter the recovery hopper for air cooling. After cooling, the rod valve is opened manually and discharged to the lime block conveyor belt.
[0014] The present application can separate the lime ring blocks from the small lime blocks and collect them separately, thus avoiding production loss and clogging of the cooler by the lime ring blocks.
[0015] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
