Description

Technical Field

[0001] The utility model belongs to the technical field of rapid cooling spraying for the discharge of rotary kilns, and particularly relates to a rapid cooling spraying device for the discharge of rotary kilns. Background Technique

[0002] After the materials inside the rotary kiln are processed, they will continuously discharge from the discharge port at the kiln head. The discharge of the rotary kiln is a complex process, and factors such as the discharge method, discharge characteristics, and post-discharge treatment need to be comprehensively considered to ensure the smooth progress of production and the stability of product quality.

[0003] When some rotary kilns discharge materials, the solid materials have a relatively high temperature. The high-temperature solid materials pose relatively high requirements for the conveying equipment and subsequent treatment processes. During storage, the high-temperature solid materials will dissipate heat to the surrounding environment, increasing the temperature inside the storage facility, easily causing damage to the storage facility, and affecting the service life of the storage equipment. In view of this, we propose a rapid cooling spraying device for the discharge of rotary kilns. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rapid cooling spraying device for the discharge of rotary kilns to solve the problems raised in the above background technique.

[0005] In view of this, the utility model provides a rapid cooling spraying device for the discharge of rotary kilns, including:

[0006] A fixed base, on which a rotary kiln body is fixedly installed. One side of the fixed base is fixedly installed with a spraying box. The discharge end of the rotary kiln body is rotatably connected to the spraying box. An annular groove is formed in the spraying box. A number of nozzles are fixedly installed in the annular groove. One end of each of the nozzles penetrates through one side of the annular groove and extends into the inner cavity of the spraying box. A leakage plate is fixedly installed in the spraying box and below the annular groove. An outlet is formed in the front side of the spraying box;

[0007] A storage tank, which is fixedly installed on the right side of the spraying box. A liquid inlet pipe is fixedly installed on the top of the storage tank. A groove is formed at the top of the liquid inlet pipe. Sliding grooves are formed on both sides of the groove at the top of the liquid inlet pipe. A filter plate is inserted and installed in the groove. Sliders are slidably installed in the sliding grooves. The tops of the two sliders are fixedly installed with the same feed hopper. Springs fixed to the inner wall of the sliding groove are fixedly installed at the bottom of the slider;

[0008] A liquid supply assembly, which is located on the storage tank and is used to convey the coolant in the storage tank to the annular groove.

[0009] In this technical solution, during use, first pour the coolant into the feed hopper. Subsequently, the coolant in the feed hopper will enter onto the filter plate. Under the action of the filter plate, impurities in the coolant can be effectively filtered, thus avoiding blockage of the nozzle by impurities. Subsequently, the filtered coolant will enter the inner cavity of the storage tank through the liquid inlet pipe;

[0010] Subsequently, when the hot solid material is discharged from the inside of the rotary kiln body to the outside, through the provided liquid supply assembly, the liquid supply assembly transports the coolant in the storage tank to the annular groove. The coolant in the annular groove will be ejected outward from several nozzles under the action of hydraulic pressure. At this time, the solid material will be discharged from the discharge end of the rotary kiln body into the spray box. Under the action of several nozzles, several nozzles are evenly distributed in a ring shape, so that the solid material entering the spray box can be sprayed with coolant, ensuring that the solid material can fully contact the coolant, thereby enabling rapid cooling of the solid material. Subsequently, the solid material will fall onto the sieve plate. When there is a large amount of solid material on the sieve plate, under the action of gravity, the solid material will slide downward and be discharged outward from the discharge port, and the staff can collect it;

[0011] When there are a large number of impurities on the filter plate that need to be cleaned, the staff can pull the feed hopper upward. Subsequently, the feed hopper will drive the two sliders to displace upward. The sliders will pull several tension springs, causing the tension springs to generate tension and elongate until the rubber pad is pulled out of the feed hopper, and a certain distance is created between the feed hopper and the filter plate. Subsequently, the filter plate can be directly taken out of the groove, and then the staff can clean the impurities on the filter plate. After cleaning, put the filter plate back into the groove. Subsequently, under the action of the tension of several tension springs, several tension springs will pull the corresponding sliders to displace downward in the chute until the top of the feed hopper contacts the top of the liquid inlet pipe, thereby being able to limit the position of the filter plate.

[0012] In the above technical solution, further, the liquid supply assembly includes:

[0013] A pump body, the pump body is fixedly installed on the top of the storage tank. The liquid inlet end of the pump body is fixedly installed with a water pipe 1. One end of the water pipe 1 penetrates through the top of the storage tank and extends into the inner cavity of the storage tank. The liquid outlet end of the pump body is fixedly installed with a water pipe 2. One end of the water pipe 2 penetrates through the right side of the spray box and extends into the annular groove.

[0014] In this technical solution, start the pump body. The pump body will extract the coolant located in the storage tank through the water pipe 1. Subsequently, the coolant will enter the water pipe 1. The coolant in the water pipe 1 will be transported by the pump body to the water pipe 2. Subsequently, the coolant in the water pipe 2 will be transported to the annular groove. The coolant in the annular groove will be ejected outward from several nozzles under the action of hydraulic pressure

[0015] In the above technical solution, further, several of the spray heads are evenly distributed in a ring shape, the leakage plate is inclined, and several of the spray heads are all located on the circumferential side of the discharge end of the rotary kiln body.

[0016] In this technical solution, it is ensured that the solid materials entering the spray box can be comprehensively sprayed with coolant; under the action of gravity, the solid materials on the leakage plate will displace towards the direction of the discharge port.

[0017] In the above technical solution, further, a box door is rotatably installed in the discharge port, a second magnet is fixedly installed at the bottom of the box door, a first magnet is fixedly installed in the discharge port and at the bottom of the second magnet, and the second magnet is magnetically connected to the first magnet.

[0018] In this technical solution, when the overall device is no longer in use, the first magnet and the second magnet will be magnetically connected, and the box door will be located in the discharge port, so as to be able to seal the discharge port and prevent external dust from entering the spray box.

[0019] In the above technical solution, further, a collection box is slidably installed in the spray box and below the leakage plate.

[0020] In this technical solution, it is ensured that the excess coolant can be collected.

[0021] In the above technical solution, further, a rubber pad inserted and matched with the feed hopper is fixedly installed at the top of the filter plate.

[0022] In this technical solution, under the action of the rubber pad, the sealing performance between the feed hopper and the filter plate can be increased, ensuring that all the coolant can pass through the filtration of the filter plate and effectively filtering out the impurities.

[0023] In the above technical solution, further, the liquid inlet pipe is communicated with the inner cavity of the storage tank.

[0024] In this technical solution, it is ensured that the filtered coolant can enter the inner cavity of the storage tank through the liquid inlet pipe.

[0025] The beneficial effects of the present utility model are:

[0026] 1. The quick cooling spray device for the discharge of the rotary kiln, through the cooperation between the spray box, the storage tank, the annular groove, the spray heads and the liquid supply assembly, ensures that the solid materials discharged from the rotary kiln body into the spray box can be sprayed with coolant, so as to cool the high-temperature solid materials, facilitate the subsequent storage of the solid materials, and avoid damage to the storage facilities.

[0027] 2. The quick cooling spray device for the discharge of the rotary kiln, through the cooperation among the feed hopper, the liquid inlet pipe and the filter plate, ensures that the coolant entering the storage tank can be filtered, preventing impurities from entering the storage tank, and thus avoiding the situation of nozzle blockage caused by impurities.

[0028] 3. The quick cooling spray device for the discharge of the rotary kiln, through the cooperation between the leakage plate and the collection box, ensures that the excess sprayed coolant can be collected, preventing the excess coolant from falling to the bottom of the inner cavity of the spray box, eliminating the need for manual cleaning and being relatively convenient.

Embodiment

[0064] This embodiment provides a rapid cooling spray device for the discharge of a rotary kiln. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The liquid inlet pipe 6 is communicated with the inner cavity of the storage tank 3.

[0065] Among them, it is ensured that the filtered coolant can enter the inner cavity of the storage tank 3 through the liquid inlet pipe 6.

[0066] Working principle: When in use, first pour the coolant into the feed hopper 7. Subsequently, the coolant in the feed hopper 7 will enter onto the filter plate 17. Under the action of the filter plate 17, the impurities in the coolant can be effectively filtered, thereby avoiding the blockage of the nozzle 15 by impurities. Under the action of the rubber pad 20, the sealing performance between the feed hopper 7 and the filter plate 17 can be increased, ensuring that all the coolant can pass through the filtration of the filter plate 17, and enabling impurities to be effectively filtered out. Subsequently, the filtered coolant will enter the inner cavity of the storage tank 3 through the liquid inlet pipe 6;

[0067] Subsequently, when the solid material at high temperature is discharged from the rotary kiln body 4 outward, the staff starts the pump body 5. The pump body 5 will extract the coolant located in the storage tank 3 through the first water pipe 8. Subsequently, the coolant will enter the first water pipe 8. The coolant in the first water pipe 8 will be transported by the pump body 5 to the second water pipe 9. Subsequently, the coolant in the second water pipe 9 will be transported to the annular groove 16.

At this time, the solid material will be discharged from the discharge end of the rotary kiln body 4 into the spray box 2. Under the action of several nozzles 15, the several nozzles 15 are evenly distributed in a ring shape, so as to be able to spray the coolant on the solid material entering the spray box 2, ensuring that the solid material can fully contact the coolant, so as to be able to quickly cool the solid material. Subsequently, the solid material will fall on the filter plate 11. When there is a lot of solid material on the filter plate 11, under the action of gravity, the solid material will slide downward and squeeze the box door 10, and the box door 10 will rotate, so that the first magnet 13 and the second magnet 23 are no longer magnetically connected.

During this process, the excess coolant will drip into the collection box 14 through the filter plate 11 for collection;

[0068] When the impurities on the filter plate 17 are more and need to be cleaned, the staff can pull the feed hopper 7 upward. Subsequently, the feed hopper 7 will drive the two sliders 18 to displace upward. The sliders 18 will pull several tension springs 19, so that the tension springs 19 will generate tension and elongate until the rubber pad 20 is pulled out of the feed hopper 7, and a certain distance is generated between the feed hopper 7 and the filter plate 17. Subsequently, the filter plate 17 can be directly taken out of the groove 22, and then the staff can clean the impurities on the filter plate 17. After cleaning, the filter plate 17 is put back into the groove 22. Subsequently, under the action of the tension of several tension springs 19, the several tension springs 19 will pull the corresponding sliders 18 to displace downward in the chute 21 until the top of the feed hopper 7 contacts the top of the liquid inlet pipe 6, so that the rubber pad 20 is inserted into the feed hopper 7 again, so as to be able to limit the filter plate 17.
