Description

Technical Field

[0001] The utility model relates to the field of wear-resistant ball calcining and cooling, in particular to a raw material calcining and cooling device for the production of wear-resistant balls. Background Art

[0002] In the process of processing wear-resistant steel balls, the existing steel ball quenching process is to send the steel balls out of the quenching furnace into a cooling basket, and the cooling basket brings the steel balls into a cooling pool to quench the steel balls with coolant.

[0003] After searching, a kind of efficient wear-resistant steel ball cooling equipment with publication number CN201920827671.3 is specifically disclosed, including a cooling pool, a cooling basket, a turntable, a guide fan and a guide fan pushing mechanism. The turntable includes a first rotating shaft and a plurality of cooling baskets connected to the first rotating shaft. The cooling basket can rotate around the first rotating shaft and is used to place wear-resistant steel balls to be immersed in the coolant for cooling; the guide fan is located on the lower side of the turntable, and a slide rail is provided on the bottom surface of the cooling pool, and the bottom of the guide fan is slidably connected to the slide rail. The guide fan pushing mechanism includes a crank and a connecting rod, and one end of the crank is vertically connected to the first rotating shaft. The beneficial effect of the utility model is that a coolant heat exchange circulation is formed inside the cooling pool, and the guide fan is linked to perform horizontal reciprocating sliding, which solves the problem that the wind force of the guide fan is not enough to push the coolant, so that the coolant heat exchange in the cooling pool is more sufficient, ensuring that the coolant temperature around the turntable is within a constant standard range, and optimizing the quenching effect.

[0004] In the traditional calcining process of wear-resistant balls, the time in the device is often insufficient, resulting in unsatisfactory cooling effect. At the same time, some coolant will often remain when taken out, and the coolant remaining on the surface needs to be wiped manually later. The most common wear-resistant ball cooling on the market is to invert the wear-resistant balls into a bucket to achieve the cooling effect, but the steel balls need to be manually salvaged after cooling, and the heat generated during the cooling process will heat the coolant, reducing the subsequent cooling effect. The general solution is to continuously replace new coolant, which also leads to waste of water resources and heat, and its practicality needs to be improved.

[0005] Therefore, it is necessary to invent a raw material calcining cooling device for wear-resistant ball production to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a raw material calcining and cooling device for the production of wear-resistant balls, which can effectively solve the above technical problems.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a raw material calcining and cooling equipment for the production of wear-resistant balls, comprising a circulation box, a cooling box is bolted to the left side of the top of the circulation box, a servo motor is bolted to the center of the top of the cooling box, a threaded transmission rod is rotatably connected to the bottom of the inner cavity of the cooling box through a bearing, a discharge pipe is connected to the lower part of the right side of the cooling box, a drying box is bolted to the right side of the top of the circulation box, a rotating shaft is rotatably connected to the upper and lower sides of the front of the inner cavity of the drying box through bearings, a conveyor belt is sleeved on the surface of the rotating shaft, a filter plate is arranged and bolted on the surface of the conveyor belt, a return pipe is connected to the bottom of the drying box, the other end of the return pipe is connected to the right side of the circulation box, a heat exchange box is bolted to the bottom of the circulation box, a water pipe is connected to the top of the heat exchange box, an upper water pipe is connected to the middle of the left side of the circulation box, and the other end of the upper water pipe is connected to the left side of the top of the cooling box.

The wear-resistant balls after cooling in the drying box are dried by the drying fan, and the liquid remaining on the surface of the wear-resistant balls will pass through the filter and enter the lower part of the inner cavity of the discharge box.

[0009] Preferably, the left side of the bottom of the discharge box is connected with a folding tube, and the other end of the folding tube is connected to the middle of the right side of the drying box. The liquid remaining on the surface of the wear-resistant ball will pass through the folding tube into the inner cavity of the drying box and enter the circulation box together with the liquid generated during the drying process.

The driving motor is used as a driving source to drive the driving wheel to rotate, and during the rotation of the driving wheel, the driven wheel will drive the driven wheel on the right side to rotate synchronously through the chain, thereby causing the driven wheel to drive the rotating shaft to rotate in the drying box.

[0011] Preferably, support plates are bolted on both sides of the front of the drying box. Since the individual mass of the metal wear-resistant balls is relatively high, the surface of the conveyor belt is easily deformed and dented due to the squeezing of gravity during the large-scale drying process. The support and limitation of the conveyor belt by the support plate maintains the shape of the conveyor belt and the stability of its operation.

[0012] Preferably, the middle part of the reflux pipe is connected to a first water pump, and the middle part of the upper water pipe is connected to a second water pump. The first water pump can pump the water accumulated in the drying box through the reflux pipe into the circulation box, so that the second water pump can pump out the cooling water after cooling and heat exchange in the circulation box, and output it to the cooling box through the upper water pipe to cool the wear-resistant balls.

[0013] Preferably, the middle part of the water pipe is connected to a third water pump, through which the cooling water in the heat exchange box is pumped into the water pipe, and heat is exchanged with the hot water heated by the wear-resistant balls in the circulation box, and the water flow after heat exchange is pumped from the water pipe into the heat exchange box, and finally discharged from the left pipe.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides Figure 1-4 The raw material calcining and cooling equipment for the production of wear-resistant balls shown in the figure includes a circulation box 1, a cooling box 2 is bolted to the left side of the top of the circulation box 1, a servo motor 3 is bolted to the center of the top of the cooling box 2, a threaded transmission rod 4 is rotatably connected to the bottom of the inner cavity of the cooling box 2 through a bearing, a discharge pipe 5 is connected to the lower part of the right side of the cooling box 2, a drying box 6 is bolted to the right side of the top of the circulation box 1, a rotating shaft 7 is rotatably connected to the upper and lower front sides of the inner cavity of the drying box 6 through bearings, a conveyor belt 8 is sleeved on the surface of the rotating shaft 7, and filter plates 9 are arranged and bolted on the surface of the conveyor belt 8, a return pipe 10 is connected to the bottom of the drying box 6, and the other end of the return pipe 10 is connected to the right side of the circulation box 1, a heat exchange box 11 is bolted to the bottom of the circulation box 1, a water pipe 12 is connected to the top of the heat exchange box 11, an upper water pipe 13 is connected to the middle of the left side of the circulation box 1, and the other end of the upper water pipe 13 is connected to the left side of the top of the cooling box 2.

[0025] A drying fan 14 is bolted to the top of the drying box 6, a discharge box 15 is bolted to the upper right side of the drying box 6, and a filter screen 16 is bolted to the center of the inner cavity of the discharge box 15. The wear-resistant balls after cooling in the drying box 6 are dried by the drying fan 14, and the liquid remaining on the surface of the wear-resistant balls will pass through the filter screen 16 and enter the lower part of the inner cavity of the discharge box 15.

[0026] The left side of the bottom of the discharge box 15 is connected to a folding tube 17, and the other end of the folding tube 17 is connected to the middle of the right side of the drying box 6. The liquid remaining on the surface of the wear-resistant ball will pass through the folding tube 17 into the inner cavity of the drying box 6 and enter the circulation box 1 together with the liquid generated during the drying process.

[0027] A driving motor 18 is bolted to the left side of the top of the circulation box 1, and a driving wheel 19 is bolted to the output end of the driving motor 18. The front of the rotating shaft 7 passes through the drying box 6 and is bolted to a driven wheel 20, and chains 21 are meshed on the surfaces of the driven wheel 20 and the driving wheel 19.

The cooling time of the wear-resistant balls can be controlled by controlling the rotation speed of the servo motor 3. After cooling, the wear-resistant balls enter the drying box 6 through the discharge pipe 5, and the upper drying fan 14 transfers hot air to the surface of the wear-resistant balls. The drive motor 18 drives the conveyor belt 8 to drive the filter plate 9 to rotate continuously in the drying box 6, pushing the wear-resistant balls to rotate to the top of the drying box 6, and pushing The water on the surface of the wear-resistant balls falls to the bottom of the drying box 6 due to the influence of the airflow, and finally enters the circulation box 1 through the reflux pipe 10. This part of the water flow is the cooling water that has been heated. At this time, cold water is poured into the heat exchange box 11 through the pipe on the right side of the heat exchange box 11, and output to the water pipe 12 through the third water pump 25, and heat is exchanged with the heated cooling water to cool the cooling water again. Finally, the cooling water in the circulation box 1 is pumped out to the cooling box 2 through the second water pump 24 to complete the cycle. The heated water flow can be transported to other areas that need hot water, thereby improving the energy utilization efficiency. Through the above-mentioned device, the cooling degree of the wear-resistant balls can be effectively controlled, and the surface of the wear-resistant balls can be in a dry state after discharge, which can effectively improve the continuous cooling efficiency of the cooling device.
