[0015] Beneficial effects

[0016] This invention provides a calcination discharge cooling device. It has the following beneficial effects:

[0017] (1) The roasting discharge cooling device, with its motor, first rotating shaft and stirring blades, allows the raw materials to be cooled when they need to be cooled. The raw materials are put into the cooling tank through the feed hole. The motor is turned on and drives the first rotating shaft to rotate, which in turn drives the stirring blades connected to the first rotating shaft to rotate. The rotation of the stirring blades causes the raw materials to rotate, thus stirring them. At the same time, the first water outlet on the stirring blades sprays water into the cooling tank, thus driving the water flow through the first water outlet to inject into the raw materials, absorbing the heat on the raw materials and cooling them. The rotation of the stirring blades can also stir the raw materials when water is injected, so that water can be injected evenly on all surfaces of the raw materials, thereby further accelerating the cooling rate of the raw materials and improving its overall efficiency. After the raw materials have cooled, the rotating cover on the cooling tank can be opened to remove the raw materials through the discharge hole, which is very convenient.

[0018] (2) The roasting discharge cooling device, through the cleaning plate and the second rotating shaft, sprays water onto the inner wall of the cooling barrel at the second water outlet when the stirring fan blades are rotating. At this time, due to the action of centrifugal force, the sliding rod on the rectangular sliding plate slides inside the sliding groove. The sliding of the rectangular sliding plate drives the second gear groove to rotate through the first gear groove, thereby driving the second rotating shaft to rotate. The rotation of the second rotating shaft drives the cleaning plate to rotate. The rotation of the cleaning plate cleans the residue on the inner wall of the cooling barrel. The sliding of the rectangular sliding plate drives the return spring to stretch. When the return spring is stretched to a certain position, the elastic force at the return spring is greater than the centrifugal force generated when the stirring fan blades rotate. Therefore, under the action of the elastic force of the return spring, the rectangular sliding plate is driven to slide back. The second rotating shaft rotates in the opposite direction, thereby driving the cleaning plate to move back and forth to clean the inner wall of the cooling barrel and prevent the residue from being stuck on the inner wall of the cooling barrel and difficult to clean.

[0019] (3) The roasting discharge cooling device, through the set smoke channel and collection pipe, when the raw material is being cooled, a large amount of smoke will be generated on the raw material. At this time, the air pump starts to generate suction and transmits the suction to the inside of the cooling barrel through the smoke channel, thereby attracting the smoke inside the cooling barrel. The smoke passes through the first filter plate on the smoke channel. At this time, the first filter hole on the first filter plate filters the large particles in the smoke. The large particles in the raw material are retained inside the cooling barrel to prevent the smoke channel from being blocked. At this time, the small particles in the smoke are transmitted to the upper part of the first filter plate and enter the inside of the collection pipe through the second filter hole on the second filter plate. Since the second filter hole has a structure of small inside and large outside, the smoke drawn inside is difficult to be transmitted to the outside through the second filter hole, thus enabling better absorption of the smoke.

[0020] (4) The roasting discharge cooling device, through the set annular water tank and rotating ring, when the water flow is injected into the raw material to cool the raw material, the wastewater will enter the top of the third filter plate through the drain hole. The third filter hole on the third filter plate can filter the larger particles in the wastewater, thereby preventing the large particles from causing secondary pollution to the water flow. At this time, the filtered wastewater enters the bottom of the third filter plate. At this time, the water flow impacts the rotating ring, thereby driving the rotating ring to rotate. Under the action of centrifugal force, the rotating ring injects the water purification agent inside the rotating ring into the inner wall of the annular water tank to purify the filtered wastewater inside the annular water tank. The water flow is then injected into the first rotating shaft through the rotating ring for recycling through the connecting water pipe, saving water resources.

[0021] (5) The roasting discharge cooling device has a splash cover. When the stirring fan blades stir the raw materials, the stirring fan blades collide and squeeze with the raw materials, so that the solid particles in the raw materials will be splashed. At this time, the splash cover covers the top outer wall of the cooling barrel, which can effectively prevent the raw materials from splashing to the outside, thereby keeping the inside of the cooling equipment clean and preventing the raw materials from splashing and adhering to the inside of the cooling equipment, which is difficult to clean.

[0040] A third filter plate 35 is fixedly connected to the inner wall of the top of the annular water tank 10.

A connecting water pipe 11 is fixedly connected to the inner wall of the second fixing hole 37.

[0041] The inner wall of one side of the annular water tank 10 is rotatably connected to multiple third rotating shafts 38 arranged in a circle. The outer wall of the top of the third rotating shaft 38 is fixedly connected to a second fixing hole 37. The outer wall of the rotating ring 39 has multiple sets of material dispensing holes 40 arranged in a circle. The rotating ring 39 has a hollow structure and the inner wall of the rotating ring 39 contains water purification agent.

[0042] The working principle of this invention is as follows: Using a motor 5, a first rotating shaft 6, and a stirring blade 15, when cooling of the raw material is required, the raw material is placed into the cooling tank 8 through the feed hole 3. The motor 5 is then turned on, driving the first rotating shaft 6 to rotate, which in turn drives the stirring blade 15 connected to the first rotating shaft 6 to rotate. The rotation of the stirring blade 15 causes the raw material to rotate, thus stirring it. Simultaneously, the first water outlet 16 on the stirring blade 15 sprays water into the cooling tank 8, causing water to flow through the first water outlet 16 and inject into the raw material, absorbing heat and cooling it. Furthermore, the rotation of the stirring blade 15 agitates the raw material during water injection, ensuring even water distribution across all surfaces of the raw material, further accelerating the cooling rate and improving overall efficiency. Once the raw material has cooled, the rotating cover 17 on the cooling tank 8 can be opened to remove it through the discharge hole 4, which is very convenient.

[0043] With the cleaning plate 20 and the second rotating shaft 29 in place, when the stirring blade 15 rotates, water is sprayed onto the inner wall of the cooling tank 8 through the second water outlet 25. At this time, due to the centrifugal force, the sliding rod 24 on the rectangular sliding plate 23 slides inside the sliding groove 22. The sliding of the rectangular sliding plate 23 drives the second gear groove 28 to rotate through the first gear groove 27, thereby driving the second rotating shaft 29 to rotate. The rotation of the second rotating shaft 29 drives the cleaning plate 20 to rotate. The rotation of the cleaning plate 20 cleans the residue on the inner wall of the cooling tank 8. At the same time, the sliding of the rectangular sliding plate 23 drives the return spring 21 to stretch. When the return spring 21 is stretched to a certain position, the elastic force at the return spring 21 is greater than the centrifugal force generated when the stirring blade 15 rotates. Therefore, under the action of the elastic force of the return spring 21, the rectangular sliding plate 23 slides back, and the second rotating shaft 29 rotates in the opposite direction, thereby driving the cleaning plate 20 to move back and forth to clean the inner wall of the cooling tank 8 and prevent the residue from being stuck on the inner wall of the cooling tank 8 and difficult to clean.

[0044] With the smoke extraction channel 12 and collection pipe 30 in place, when the raw material is being cooled, a large amount of smoke is generated on the raw material. At this time, the air pump 13 starts to generate suction, which is transmitted to the inside of the cooling barrel 8 through the smoke extraction channel 12, thereby attracting the smoke inside the cooling barrel 8. The smoke passes through the first filter plate 31 on the smoke extraction channel 12. At this time, the first filter hole 32 on the first filter plate 31 filters the large particles in the smoke. The large particles in the raw material are retained inside the cooling barrel 8, preventing the smoke extraction channel 12 from becoming blocked. At this time, the small particles in the smoke are transmitted to the upper part of the first filter plate 31 and enter the inside of the collection pipe 30 through the second filter hole 34 on the second filter plate 33. Since the second filter hole 34 has a structure that is smaller inside and larger outside, the smoke drawn in inside is difficult to be transmitted to the outside through the second filter hole 34, thus enabling better absorption of the smoke.

[0045] With the annular water tank 10 and rotating ring 39, when water is injected into the raw material to cool it, the wastewater enters the top of the third filter plate 35 through the drain hole 19. The third filter hole 36 on the third filter plate 35 can filter larger particles in the wastewater, thus preventing secondary pollution of the water flow by large particles. After filtration, the wastewater enters the bottom of the third filter plate 35. At this time, the water flow impacts the rotating ring 39, causing the rotating ring 39 to rotate. Under the action of centrifugal force, the water purification agent inside the rotating ring 39 is injected into the inner wall of the annular water tank 10 to purify the wastewater filtered inside the annular water tank 10. The water is then injected into the first rotating shaft 6 through the rotating ring 7 via the connecting water pipe 11 for recycling, thus saving water resources.

[0046] With the splash guard 9 in place, when the stirring blades 15 stir the raw materials, the stirring blades 15 collide and squeeze with the raw materials, which causes the solid particles in the raw materials to splash. At this time, the splash guard 9 covers the top outer wall of the cooling tank 8, which can effectively prevent the raw materials from splashing to the outside, thereby keeping the inside of the cooling equipment body 1 clean and preventing the raw materials from splashing and adhering to the inside of the cooling equipment body 1 and making them difficult to clean.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
