Description

Technical Field

[0001] The invention relates to the technical field of rotary kilns, and in particular to a rapid condensation rotary kiln. Background Art

[0002] Rotary kiln is a kind of equipment widely used in industrial production. It can produce a variety of important materials through rotation and high temperature.

[0003] When the existing rotary kiln heats the material in the rotary kiln, the material in the rotary kiln is easily liquefied or even vaporized. If the vaporized material is directly transported out of the rotary kiln, it is easy to cause a waste of resources.

[0004] In a long rotary kiln, it usually includes a feeding section, a heating section and a discharging section. The temperatures of the discharging section and the heating section are higher than that of the feeding section. Since the rotary kiln is usually set at an angle, the height of the feeding section is higher than that of the discharging section. Part of the vaporized material floats upward along the inner wall of the rotary kiln to the feeding section, and the other part is discharged from the discharging section and enters the condensation mechanism together with the remaining gas. The condensed material is then transported back to the feeding section of the rotary kiln for reheating, resulting in low working efficiency. Summary of the invention

[0005] The object of the present invention is to provide a rapid condensation rotary kiln, which can condense vaporized materials in the kiln body and directly mix them with solid or liquid materials in the kiln body and then continue to heat them, and has high working efficiency.

[0006] In order to solve the above technical problems, the present invention adopts the following solutions:

An air pipe is provided through the kiln body. A plurality of air outlets are provided on the air pipe along the extension direction of the air pipe. In the direction from the discharge section to the feed section, the angle between the axis of the air outlet and the axis of the kiln body from the discharge section to the feed section increases from an acute angle to a right angle as the distance between the air outlet and the discharge section increases. An exhaust fan is arranged on the side of the kiln tail away from the kiln head. The existing technology is used to seal the air pipe and the kiln tail. A conveyor belt is arranged in the kiln head below the discharge section for receiving heated materials. The exhaust fan, the conveyor belt, the heating device for the kiln body, the driving device for rotating the kiln body and the supporting device all adopt the existing technology and are not described in detail. Its function is that, through the arrangement of the gas transmission pipe passing through the kiln body and the arrangement of the axial direction of the air outlet hole, the vaporized material in the kiln body can be blown from the discharge section to the condensation device and the solid or liquid material at the bottom of the kiln body. After condensation at the condensation device, it is directly mixed with the solid or liquid material in the kiln body and then continued to be heated, with high working efficiency.

The gas outlet sections are arranged horizontally and different gas outlet sections are arranged parallel to each other. Each gas outlet section has at least three gas outlet holes along the axial direction of the gas outlet section. Its function is that, through the arrangement of the gas outlet section, the width of the gas ejected from the gas delivery pipe in the kiln body can be expanded, thereby enhancing the drainage effect.

[0009] Furthermore, a feed channel is provided at the kiln tail, and the feed channel includes a feed section extending into the feed section, and the condensation device includes a condensation pipe, and the condensation pipe includes a kiln condensation section surrounding the feed section.

The feed section is inclined downward toward the kiln head, and a liquid guide channel is provided below the feed section parallel to the feed section. The bottom end of the liquid guide channel extends into the kiln body, and the liquid guide channel is used to collect the condensate falling from the feed section and input it into the kiln body. Its function is that through the setting of the condensation section in the kiln, the area where the feed section is located can be condensed.

[0010] Furthermore, the condenser tube includes a liquid inlet section for inputting condensate and a liquid outlet section for outputting condensate, and the condenser tube also includes a kiln outer condensation section surrounding the liquid inlet section. Its function is that, through the setting of the kiln outer condensation section, the airflow in the gas pipeline before entering the kiln body can be cooled, so that the airflow ejected from the gas pipeline in the feed section is at a lower temperature, thereby improving the condensation effect.

[0011] Furthermore, the condensation device also includes a condensation net located between the feeding section and the gas transmission pipe, the condensation net includes a temperature conducting member located between the condensation section in the kiln and the top of the feeding section and a collection net for collecting condensate, the temperature conducting member is in contact with the condensation tube, and the collection net is arranged on the axis of at least one air outlet. Its function is that, through the arrangement of the temperature conducting member, the temperature of the condensation tube can be transferred to the collection net; through the arrangement of the collection net, the liquefied product passing through the collection net can be condensed and collected, and when the condensate collected on the collection net is large and heavy, it will drip into the kiln body by itself; through the design of the position relationship between the collection net and the air outlet, the airflow blown out of the air outlet can blow off the condensate on the collection net.

[0012] Furthermore, a hook bent toward the condensation net is provided on the bottom surface of the temperature conducting member, and a hook groove for embedding the hook is provided on the top surface of the feeding section. The function of the hook and the hook groove is to prevent the temperature conducting member from falling off the feeding section.

[0013] Furthermore, the condensation net includes a swinging section arranged between the temperature conducting member and the collection net, a windshield structure for blocking the gas in the gas pipe from being transported toward the kiln head is arranged on the gas transmission pipe, the windshield structure is located on the section where the gas outlet hole with an axis passing through the collection net is located or on the section where the previous gas outlet hole between the gas outlet hole and the feeding section is located, and a trigger block for pushing the windshield structure to block the gas flow in the gas transmission pipe during the rotation of the rotary kiln is arranged on the inner wall of the rotary kiln. The swinging section is made of elastic material. Its function is that, through the setting of the swinging section, the collection net can swing up and down around the swinging section, which is convenient for shaking off the condensate on the collection net; through the setting of the windshield structure, the wind pressure of the air outlet on the collection net is reduced, so that the wind pressure received by the collection net changes, and the amplitude of the up and down swing of the collection net is increased by relying on the rebound force of the swinging section, which is convenient for further shaking off the condensate on the collection net.

[0014] Furthermore, the windshield structure includes a pressure-bearing member for contacting the trigger block and a windshield member for blocking the flow of gas in the gas pipe, which are sequentially connected from top to bottom, and a reset spring is provided between the windshield member and the gas pipe. The top surface of the pressure-bearing member and the surface of the trigger block facing the axis of the kiln body are both convex spherical. Its function is that, through the arrangement of the pressure-bearing member and the windshield member, when the trigger block contacts the pressure-bearing member, the pressure-bearing member is pressed to move downward, driving the windshield member to move downward, blocking the flow path of the gas, thereby reducing the gas output of the subsequent gas outlet, causing the wind pressure on the collection network to change and shake.

[0015] Furthermore, the top surface of the gas delivery pipe is provided with a bottom surface for supporting the return spring and a support pipe for the windshield to pass through, the outer wall of the windshield is provided with a pressure ring for pressing on the top surface of the return spring, and the integral outer shell composed of the pressure-bearing part, the windshield and the return spring is provided with a threaded sleeve for threaded connection with the support pipe.

Its function is that, through the setting of the heat insulation board, the heat flow can be blocked from blowing directly to the condensing device, so as to avoid greatly affecting the condensation effect.

[0018] The present invention has the beneficial effects:

[0019] 1. Through the arrangement of the gas transmission pipe passing through the kiln body and the arrangement of the axial direction of the gas outlet hole, the vaporized material in the kiln body can be blown from the discharge section to the condensation device, and after condensation at the condensation device, it is directly mixed with the solid or liquid material in the kiln body and then continued to be heated, with high working efficiency;

[0020] 2. Through the setting of the condensation section in the kiln, the area where the feeding section is located can be condensed;

The condensation pipe 8 itself is a conventional prior art, and its condensation principle and related equipment are not described in detail. The feed section 7 is inclined downward toward the kiln head 1. A liquid guide channel is provided below the feed section 7 in parallel with the feed section, and the bottom end of the liquid guide channel extends into the kiln body 2. The liquid guide channel is used to collect the condensate falling from the feed section 7 and input it into the kiln body 2. Its function is that through the setting of the kiln condensation section 11, the area where the feed section is located can be condensed.

[0035] Specifically, Figure 1 As shown, the condenser 8 includes a liquid inlet section 9 for inputting condensate and a liquid outlet section 10 for outputting condensate, and the condenser 8 also includes an outer kiln condensation section surrounding the liquid inlet section 9. Its function is that, through the provision of the outer kiln condensation section, the airflow in the gas delivery pipe 4 before entering the kiln body 2 can be cooled, so that the temperature of the airflow ejected from the gas delivery pipe 4 in the feed section is relatively low, thereby improving the condensation effect.

The swinging section 16 is made of elastic material. Its function is, through the setting of the swing section 16, the collecting net 14 can swing up and down around the swing section 16, so as to shake off the condensate on the collecting net 14; through the setting of the wind shielding structure 17, the wind pressure of the air outlet on the collecting net 14 is reduced, so that the wind pressure received by the collecting net 14 changes, and the amplitude of the up and down swinging of the collecting net 14 is increased by relying on the rebound force of the swing section 16, so as to further shake off the condensate on the collecting net 14.

[0039] Specifically, Figure 3 As shown, the wind shield structure 17 includes a pressure-bearing member 19 for contacting the trigger block 18 and a wind shield 20 for blocking the flow of gas in the gas pipe 4, which are sequentially connected from top to bottom. A reset spring 21 is provided between the wind shield 20 and the gas pipe 4. The top surface of the pressure-bearing member 19 and the surface of the trigger block 18 facing the axis of the kiln body 2 are both convex spherical. Its function is that, through the arrangement of the pressure-bearing member 19 and the wind shield 20, when the trigger block 18 contacts the pressure-bearing member 19, the pressure-bearing member 19 is pressed to move downward, driving the wind shield 20 to move downward, blocking the flow path of the gas, thereby reducing the gas output of the subsequent gas outlet 5, causing the wind pressure on the collection net 14 to change and shake.

[0040] Specifically, Figure 4 As shown, the top surface of the gas delivery pipe 4 is provided with a bottom surface for supporting the return spring 21 and a support pipe 22 for the windshield 20 to pass through, the outer wall of the windshield 20 is provided with a pressure ring 23 for pressing on the top surface of the return spring 21, and the integral outer shell composed of the pressure-bearing member 19, the windshield 20, and the return spring 21 is provided with a threaded sleeve 24 for threaded connection with the support pipe 22. Its function is that, through the arrangement of the support pipe 22 and the threaded sleeve 24, the movement of the pressure-bearing member 19 and the windshield 20 can be guided and protected.

[0041] Specifically, Figure 4 As shown, the windshield 20 is provided with a blind hole 25 for the bottom end of the pressure-bearing member 19 to enter at one end facing away from the gas delivery pipe 4, the windshield 20 is threadedly connected with the pressure-bearing member 19, and a pressure plate 26 for pressing on the top surface of the outer edge is provided on the threaded sleeve 24. Its function is to facilitate the installation of the windshield structure 17 through the design of the windshield 20 and the pressure-bearing member 19 structure.

[0042] Specifically, Figure 1 As shown, a heat insulation board 27 is provided on the gas delivery pipe 4 near the condensing device in the heating section. Figure 5 As shown, the heat insulation board 27 is provided with a mounting hole 28 for mounting on the gas pipe 4, the mounting hole 28 is prism-shaped, the section on the gas pipe 4 for mounting the heat insulation board 27 is prism-shaped with the same shape and size as the mounting hole 28, the outer diameter of the heat insulation board 27 is smaller than the inner diameter of the kiln body 2, and there is a gap for passing materials between the bottom of the heat insulation board 27 and the kiln body 2. The heat insulation board 27 adopts the heat insulation material in the prior art, which will not be described in detail. The heat insulation board 27 includes an upper plate and a lower plate, a part of the mounting hole 28 is located on the upper plate, and the other part of the mounting hole 28 is located on the lower plate, and both the upper plate and the lower plate are provided with tooth structures, the tooth structures on the upper plate and the tooth structures on the lower plate are meshed, and the side of the heat insulation board 27 is threadedly connected with bolts that penetrate the tooth structures on the upper plate and the tooth structures on the lower plate at the same time. Its function is that, through the setting of the heat insulation board 27, it can prevent the heat flow from blowing directly to the condensation device, so as to avoid greatly affecting the condensation effect.

[0043] The working principle of this embodiment is described as follows: low-temperature gas is transported into the kiln body 2 through the gas pipe 4, and the gas at the discharge section first passes through the heating section. Therefore, the gas in the discharge section is first heated by the heating section. Therefore, the temperature of the gas ejected from the discharge section and the heating section is relatively high, which has little effect on the heating process of the material. It mainly plays a drainage role, blowing the vaporized material to the condensation device along with the heat flow. Most of the heat flow is blocked by the insulation board 27 when passing through the insulation board 27, part of the heat flow is blown to the logistics below by the airflow, and part of it flows to the condensation network 12 through the gap between the insulation board 27 and the top of the kiln body 2. When the vaporized material passes through the collecting net 14, due to the low temperature of the collecting net 14, the vaporized material condenses on the collecting net 14, and through the rotation of the kiln body 2, the trigger block 18 intermittently presses the pressure bearing member 19, so that the wind shield 20 intermittently blocks the airflow in the gas pipe 4, and the wind pressure on the collecting net 14 changes intermittently and shakes up and down. Through the up and down shaking of the collecting net 14, the condensate on the collecting net 14 falls on the bottom of the kiln body 2 and mixes with the material at the bottom of the kiln body 2. When the vaporized material passes through the area where the condensation section 11 in the kiln is located, it condenses near the condensation section 11 in the kiln and falls on the liquid guide channel to flow into the kiln body 2.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. According to the technical essence of the present invention, within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the present invention.
