Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a vacuum rake dryer. Background Art

[0002] Vacuum rake dryer is a novel horizontal intermittent vacuum drying equipment. The wet material is evaporated by conduction, and the scraper agitator continuously removes the material on the hot surface and pushes it in the container to form a circulating flow. After the water evaporates, it is pumped out by the vacuum pump. Vacuum rake dryer is widely used in the drying operation of organic semi-finished products and fuels in the chemical industry.

[0003] During the production of some vacuum rake dryers, heating plates are added to the inner wall of the cylinder for heating treatment. However, the materials of some cylinders are relatively simple, which makes the temperature of the outer wall of the cylinder higher after heating. Once maintenance is required, the hot cylinder cannot be approached by people, and it needs to cool down naturally for a period of time, which prolongs the maintenance time and reduces the overall maintenance efficiency.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A vacuum rake dryer includes a dryer body 1, a feed port 11 is provided at the upper end of the dryer body 1, a discharge valve 13 is provided at the lower end, rake teeth 12 are provided in the inner cavity of the dryer body 1, a driving component 2 for driving the rake teeth 12 to rotate is provided on one side of the dryer body 1, a protective cover 3 is provided at the bottom of the dryer body 1, and the protective cover 3 is sleeved on the outside of the discharge valve 13, a cooling unit 6 is provided on one side of the dryer body 1, the dryer body 1 and the driving component 2 are both prior arts, and the specific structure and working principle of the feed port 11, rake teeth 12 and discharge valve 13 do not need to be described in detail, and are well known to personnel in the field of vacuum rake dryers, so they are not elaborated.

[0023] The cooling unit 6 includes a mounting frame 61, a water pump 63 is installed in the middle of the mounting frame 61, a water pumping pipe 62 is connected to the water pumping end of the water pump 63, a water supply pipe 64 is connected to the output end of the water pump 63 away from the water supply pipe 62, and a spraying pipe 65 is connected to the other end of the water supply pipe 64 away from the water pump 63.

[0024] Among them, the spray pipe 65 is arranged at the bottom end of the top frame of the mounting frame 61, and the spray pipe 65 is located on both sides of the feed port 11, and the spray head of the spray pipe 65 is aimed at the dryer body 1 below. The spray pipe 65 sprays coolant, so that the coolant flows to the outer wall of the cylinder of the dryer body 1, thereby quickly cooling the outer wall of the cylinder with a higher temperature.

[0025] In addition, a collecting box 7 is arranged below the discharge valve 13, and a first water collecting box 4 and a second water collecting box 5 are respectively arranged on the outer sides of the collecting box 7. The second water collecting box 5 is arranged on a side close to the cooling unit 6, and a drainage hole is arranged on the second water collecting box 5. A pumping pipe 62 is connected to the drainage hole of the second water collecting box 5. Cooling liquid can be introduced into the second water collecting box 5 to facilitate the water pump 63 to extract through the pumping pipe 62, and the cooling liquid can be recycled by collecting the dripping cooling liquid.

[0026] Among them, the first water collecting tank 4 is spliced ​​and placed on the front side of the second water collecting tank 5. A handle is provided on the side wall of the first water collecting tank 4. The handle of the water collecting tank 4 is convenient for the operator to pull out the water collecting tank 4, thereby pouring out the water inside, and at the same time, the collected dried materials in the collecting box 7 can be taken out.

[0027] In addition, part of the side wall of the first water collecting tank 4 and part of the side wall of the second water collecting tank 5 are in contact with each other, and a clamping plate 8 is inserted at the side wall where the first water collecting tank 4 and the second water collecting tank 5 contact each other. The clamping plate 8 can clamp the two water collecting tanks 5 on both sides to prevent them from separating, and the coolant will flow out from the gap to the ground.

[0028] Moreover, a tempered glass 31 is provided on the side wall of one side of the protective cover 3, and a guide part 32 is provided at the bottom of the protective cover 3. The guide part 32 is inclined at a certain angle, which facilitates the liquid flowing onto the protective cover 3 to be introduced into the two water collecting tanks below.

[0029] In this embodiment, after the dryer body 1 has been working for a long time and has dried the material, when the operator needs to repair the inside or outside of the cylinder, the cylinder is at a high temperature due to the heating of the heating plate, and the cooling unit 6 can be used to cool it down.

[0030] First, pour the coolant into the second water collecting tank 5, and then start the water pump 63. The water pump 63 extracts the coolant from the second water collecting tank 5 through the suction pipe 62, and then transports the coolant to the spray pipe 65 through the water pipe 64 to spray it out. The coolant continues to flow on the cylinder of the dryer main body 1 to cool down the cylinder of the dryer main body 1 with a higher temperature, so that its temperature can be quickly reduced, and the coolant will flow into the first water collecting tank 4 and the second water collecting tank 5 below due to the effect of gravity.

[0031] The coolant that flows back into the second water collecting tank 5 is recycled and will not be wasted. After cooling is completed, the operator can pull out the clamping plate 8, pull it out through the handle on the first water collecting tank 4, separate it from the second water collecting tank 5, and pour the collected coolant into the first water collecting tank 4.

[0032] When the dryer body 1 is working normally, the first water collecting box 4 can be pulled out to facilitate the placement and removal of the collecting box 7, and the tempered glass 31 on the protective cover 3 is convenient for the operator to observe the operating status of the discharge valve 13.

[0033] In the present invention, by setting up the cooling unit 6, when the dryer body 1 needs to be inspected and repaired after working for a long time, the cooling unit 6 is started, and the coolant in the second water collecting tank 5 is transported by the water pump 63, so that the spray pipe 65 can spray the coolant onto the outer wall of the cylinder of the dryer body 1 with a higher temperature, thereby quickly cooling it. This cooling is faster than natural cooling, so that the dryer body 1 with a higher temperature can be cooled faster, which is convenient for the operator to inspect and repair it faster, and effectively improves the efficiency of inspection and maintenance.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
