Description

Technical Field

[0001] The invention relates to the technical field of grinding ball cooling, in particular to a grinding ball high-temperature cooling device. Background Art

[0002] Wear-resistant steel balls are a kind of crushing medium used in ball mills. They are used to crush materials in the mill. During the processing, the wear-resistant steel balls need to be quenched. The temperature of the wear-resistant steel balls after quenching is relatively high. Therefore, the wear-resistant steel balls need to be sent to cooling equipment for cooling and spraying.

[0003] The prior art patent announcement number is CN218262627U, and the name is a cooling device for processing wear-resistant steel balls. The above patent sprays water on the surface of the wear-resistant steel balls through a nozzle, and circulates back to the water tank through the cooperation of the filter plate and the first valve. The temperature of the wear-resistant steel balls is reduced by water circulation heat exchange. The steam generated after the wear-resistant steel balls are sprayed with water enters the air outlet pipe, and the baffle floats upward under pressure to achieve steam entry. The steam dissipates heat through the continuous wavy heat sink to form water droplets, avoiding water evaporation loss, and circulates back to the water tank through the water collecting box, the second valve and the connecting pipe, thereby reducing water resources;

[0004] However, in reality, the above patent mainly utilizes a conveyor belt to transport grinding balls in a processing box. During the transportation process, the grinding balls are stationary on the surface of the conveyor belt, and the nozzle is placed above the conveyor belt to spray from top to bottom. As a result, only the upper end of the grinding balls can be sprayed and cooled, while the lower end of the grinding balls close to the conveyor belt is difficult to contact with water. The spray cooling effect is generally poor, which leads to uneven cooling of the grinding balls. Summary of the invention

During the transportation process, the grinding balls are stationary on the surface of the conveyor belt, and the nozzle is placed above the conveyor belt to spray from top to bottom, so that only the upper end of the grinding balls can be sprayed and cooled, while the lower end of the grinding balls close to the conveyor belt is difficult to contact with water, and the spray cooling effect is generally poor, which leads to uneven cooling of the grinding balls.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: a high-temperature grinding ball cooling device, comprising a cooling box, a chain plate conveyor body installed between the inner walls of both sides of the cooling box for conveying grinding balls, and a spray mechanism arranged above the chain plate conveyor body for cooling and lowering the temperature of the grinding balls, both sides of the cooling box are provided with material ports, and the two ends of the chain plate conveyor body respectively pass through the two material ports, and the device is characterized in that it also includes a rotating grinding ball bearing mechanism arranged on the chain plate conveyor body;

[0007] The rotating grinding ball bearing mechanism includes a bearing platform arranged above one end of the chain conveyor body and lifting supports arranged on both sides of the bearing platform. The bearing platform is composed of three groups of mounting seats. A plurality of spherical grooves for placing grinding balls are equidistantly arranged on the mounting seats. Both ends of the spherical grooves are connected to the outside. A grinding ball driving component is arranged below the mounting seat. Self-actuating lifting members cooperating with the lifting supports are arranged on the inner walls on both sides of the cooling box.

[0009] Preferably, the self-actuated lifting member is a fixed plate, one section of the fixed plate is located outside the cooling box and is inclined, and the other section of the fixed plate is fixed on the inner wall of the cooling box and is horizontal.

[0010] Preferably, the lifting support also includes a sliding groove vertically opened on a side of the sliding seat away from the mounting seat, and a pressure roller is slidably arranged in the sliding groove, one end of the pressure roller contacts the inclined surface of the fixed plate, and the other end of the pressure roller is fixed to the slide plate.

[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] Reference Figure 1-4 As shown, a grinding ball high temperature cooling device comprises a cooling box 1, a chain plate conveyor body 3 installed between the inner walls of both sides of the cooling box 1 for conveying grinding balls, and a spray mechanism arranged above the chain plate conveyor body 3 for cooling the grinding balls. Both sides of the cooling box 1 are provided with material ports 2, and two ends of the chain plate conveyor body 3 respectively pass through two material ports 2, and the chain plate conveyor body 3 divides the interior of the cooling box 1 into two chambers, wherein the chamber located at the lower side contains water;

[0025] The spray mechanism includes a plurality of water pipes 8 equidistantly fixed between the inner walls of both sides of the cooling box 1, a plurality of nozzles 9 equidistantly connected and fixed on the pipe body of the water pipes 8, and a connecting pipe 6 transversely arranged above one side wall of the cooling box 1, the water outlet end of the nozzle 9 faces the chain conveyor body 3, one end of the water pipe 8 penetrates the cooling box 1 and is fixedly connected with the connecting pipe 6, a water pump 4 is installed at the bottom of one side wall of the cooling box 1, the absorption end of the water pump 4 is fixedly connected with a water suction pipe 5, the end of the water suction pipe 5 penetrates into the cooling box 1, and a water outlet pipe 7 is fixedly connected between the water outlet end of the water pump 4 and the connecting pipe 6;

[0026] By setting the spray mechanism and the chain conveyor body 3, when the grinding balls are to be cooled, the grinding balls to be cooled can be placed in advance from one end of the chain conveyor body 3, and then the chain conveyor body 3 is turned on, and the chain plates of the chain conveyor body 3 are operated to convey the grinding balls to the inside of the cooling box 1, and then the water pump 4 in the spray mechanism is turned on, and the absorption end of the water pump 4 continuously draws water from the suction pipe 5 to the lower inside of the cooling box 1, so that the water is conveyed into the water pipe 8 through the outlet pipe 7 and the connecting pipe 6, and finally sprayed outwardly from the nozzle 9, so that the water sprays the grinding balls on the chain plates of the chain conveyor body 3 from top to bottom, which plays a role in cooling the grinding balls, and the water sprayed from the nozzle 9 can still drip into the inner bottom of the cooling box 1 through the gap between the chain plates of the chain conveyor body 3, so as to achieve a recycling effect.

[0027] However, in practice, the above embodiment mainly utilizes the chain conveyor body 3 to convey the grinding balls in the cooling box 1. During the conveying process, the grinding balls are stationary on the chain surface of the chain conveyor body 3, and the nozzle 9 is placed above the chain conveyor body 3 to perform spraying from top to bottom, so that only the upper end of the grinding balls can be sprayed and cooled, while the lower end of the grinding balls close to the chain conveyor body 3 is difficult to contact with water, and the spray cooling effect is generally poor, which leads to uneven cooling of the grinding balls.

[0028] For this purpose, refer to Figure 2 and Figure 3 As shown, it is worth noting that it also includes a rotating grinding ball bearing mechanism arranged on the chain conveyor body 3;

[0029] The rotating grinding ball bearing mechanism includes a bearing platform arranged above one end of the chain plate conveyor body 3, the bearing platform is composed of three sets of mounting seats 10, a plurality of spherical grooves for placing grinding balls are arranged at equal intervals on the mounting seats 10, both ends of the spherical grooves are connected to the outside, and a grinding ball driving component is arranged below the mounting seats 10;

[0030] By setting a rotating grinding ball bearing mechanism and utilizing a plurality of spherical grooves on the mounting seat 10, it is convenient to manually place the grinding balls to be cooled one by one, so that the grinding balls are spaced and distributed to avoid contact with each other and affect the spray cooling effect. When the chain conveyor body 3 is started to move the mounting seat 10 to the inside of the cooling box 1, the grinding ball driving component can move the grinding balls in real time from below the mounting seat 10, so that the grinding balls are rotated in the spherical grooves under the spray cooling, so that the grinding balls are fully in contact with the water to be cooled, thereby enhancing the uniformity of cooling.

[0031] Further, refer to Figure 1-3 As shown, it is worth noting that the rotating grinding ball bearing mechanism also includes lifting supports arranged on both sides of the bearing platform, and the inner walls on both sides of the cooling box 1 are provided with self-actuating lifting members matched with the lifting supports;

[0032] The lifting support includes a slide 11 vertically fixed on the top surface of the chain plate of the chain plate conveyor body 3 and a slide plate 12 slidably arranged inside the slide 11, and the top of the slide plate 12 is fixedly connected to the side wall of the middle mounting seat 10;

[0033] The self-actuating lifting member is a fixed plate 13, one section of the fixed plate 13 is located outside the cooling box 1 and is inclined, and the other section of the fixed plate 13 is fixed on the inner wall of the cooling box 1 and is horizontal;

[0034] The lifting support further includes a sliding slot 14 vertically opened on a side of the slide 11 away from the mounting seat 10, a pressing roller 15 is slidably arranged in the sliding slot 14, one end of the pressing roller 15 contacts the inclined surface of the fixing plate 13, and the other end of the pressing roller 15 is fixed to the slide plate 12;

[0035] By setting the lifting support and the self-actuated lifting member, when the chain conveyor body 3 is started and the bearing platform carries the grinding balls to the inside of the cooling box 1, the pressure roller 15 in the lifting support can slide from the inclined section of the fixed plate 13 to its horizontal section in advance. When passing through the inclined section of the fixed plate 13, the pressure roller 15 can slide from bottom to top along the slope to lift the slide plate 12, so that the slide plate 12 slides on the inner side of the slide seat 11 and pushes up the bearing platform, driving the distance between the bearing platform and the water pipe 8 to be reduced when in the cooling box 1, thereby improving the contact effect between the grinding balls and the water liquid and further enhancing the cooling quality of the grinding balls.

[0036] Further, refer to Figure 4 As shown, it is worth noting that the grinding ball driving component includes a spiral auger 17 disposed transversely below the mounting seat 10 and a fixing plate 16 rotatably connected to one end of the spiral auger 17, and the fixing plate 16 is vertically fixed to the bottom surface of the mounting seat 10;

[0037] Since the bottom ends of the spherical grooves are connected to the outside, when the grinding balls are placed in the spherical grooves, the grinding balls can contact the spiral auger 17. When the spiral auger 17 rotates, the threaded pieces on the spiral auger 17 can continuously move the grinding balls, causing the grinding balls to rotate in the spherical grooves.

[0038] Further, refer to Figure 4 As shown, it is worth noting that a second transmission belt 19 is connected between the ends of the spiral auger 17 on both sides, and a first transmission belt 18 is connected between the ends of the middle spiral auger 17 and the ends of the right spiral auger 17;

[0039] One end of the right spiral auger 17 rotates through the fixed plate 16 and is fixed with a transmission column 20, a transmission gear 21 is tightly sleeved on the rod of the transmission column 20, and a fixed tooth plate 22 that can mesh with the transmission gear 21 is transversely fixed on the inner wall of the cooling box 1, and the fixed tooth plate 22 is located above the fixed plate 13;

[0040] When the load-bearing platform is lifted upwards through the oblique section of the fixed plate 13, the load-bearing platform further moves toward the inside of the cooling box 1 along with the chain conveyor body 3, and the transmission gear 21 can mesh with the fixed tooth plate 22, and then the transmission column 20 is driven by force to rotate the right-side spiral auger 17. In the process of rotating the right-side spiral auger 17 to move the grinding balls on its rod, the first transmission belt 18 and the second transmission belt 19 can synchronously drive the middle and left-side spiral auger 17, so that the middle and left-side spiral auger 17 can synchronously move the grinding balls.
