AI Technical Summary
In the current peat dehydration and drying process, large clumps are easily formed, making it difficult for internal moisture to seep out. This requires extending the drying time or increasing the hot air temperature, which increases the unit energy consumption. Furthermore, the local area where the clumps contact the drum is prone to being over-dried, while the inside remains moist. The hot and humid environment leads to a low rate of moisture evaporation, creating a vicious cycle.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of peat dehydration technology, specifically to a peat high-efficiency dehydration and drying equipment. Background Technology
[0002] Currently, drum dryers are commonly used for dehydrating and drying peat. However, during the drying process using drum dryers, peat is prone to forming large clumps due to its stickiness, making it difficult for internal moisture to seep out. This requires extending the drying time or increasing the hot air temperature, leading to increased energy consumption per unit area. Furthermore, the localized areas where the clumps contact the drum are prone to becoming too dry, while the interior remains damp. At the same time, the high humidity gas inside the drum cannot be discharged during the drying process, resulting in a low rate of moisture evaporation. The hot and humid environment causes the peat surface to become damp again, creating a vicious cycle where the peat becomes stickier the longer it is dried. Utility Model Content
[0003] The purpose of this invention is to provide a high-efficiency peat dehydration and drying device to solve the problems in the background technology mentioned above, where peat easily forms large clumps due to its stickiness during the drying process, making it difficult for internal moisture to seep out. This requires extending the drying time or increasing the hot air temperature, resulting in increased energy consumption per unit. Furthermore, the local area where the clumps contact the drum is prone to over-drying, while the inside remains damp. At the same time, high-humidity gas cannot be discharged from the drum during the drying process, resulting in a low moisture evaporation rate. The hot and humid environment causes the peat surface to become damp again, creating a vicious cycle where the peat becomes stickier the longer it is dried.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a peat high-efficiency dehydration and drying equipment, including a stirring component installed inside a drum dryer, and auxiliary components installed inside therein;
[0005] The stirring assembly includes a rotating rod, which is rotatably embedded inside a drum dryer. An inner cylinder is rotatably embedded inside the drum dryer, and the rotating rod is rotatably embedded inside the inner cylinder. Multiple stirring rods are fixedly connected to the outer surface of the rotating rod, and each of the multiple stirring rods is equipped with a powder nozzle.
[0006] The auxiliary component includes an air pump, which is fixedly connected to the top of the outer surface of the drum dryer. A drying device is fixedly connected to the top of the outer surface of the drum dryer. An air supply pipe is provided inside the air pump, and the end of the air supply pipe away from the air pump is located inside the drying device.
[0007] Preferably, the rotating rod is provided with a feed pipe inside, the drying device is provided with a return air pipe inside, and the end of the return air pipe away from the drying device is located inside the feed pipe.
[0008] Preferably, a drive motor is fixedly connected to the bottom of the outer surface of the drum dryer, and the output shaft of the drive motor is fixedly connected to the rotating rod.
[0009] Preferably, a feed inlet is fixedly connected to the top of the outer surface of the drum dryer.
[0010] Preferably, the drum dryer has a liquid outlet inside and a material outlet inside.
[0011] Preferably, the bottom of the outer surface of the drum dryer is fixedly connected with multiple support legs.
[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0013] This invention introduces materials into a drum dryer through a feed inlet. The inner drum rotates, centrifugally dehydrating the materials. During this dehydration process, a drive motor is activated, rotating a rotating rod in the opposite direction to the inner drum. A dispersant, such as diatomaceous earth or sawdust, is added to the rotating rod through a feed pipe located inside the rotating rod and unaffected by its rotation. The dispersant is discharged through multiple powder nozzles inside a stirring rod connected to the rotating rod. This design allows the mechanical crushing action of the stirring rod to directly break up peat clumps and disrupt the hard shell structure formed by the stickiness of humus. Simultaneously, the dispersant, such as diatomaceous earth and sawdust, sprayed through the powder nozzles, forms an inert insulating layer on the surface of the peat particles, reducing inter-particle adhesion and preventing clumping at its source. This keeps the peat material loose, significantly increasing the contact area with the hot air inside the drum and ensuring a smoother moisture evaporation path. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 A peat high-efficiency dehydration and drying device includes a stirring component installed inside a drum dryer 1, and auxiliary components installed inside therein;
[0021] The stirring assembly includes a rotating rod 3, which is rotatably embedded inside the drum dryer 1. The drum dryer 1 is rotatably embedded inside an inner cylinder 2. The rotating rod 3 is rotatably embedded inside the inner cylinder 2. Multiple stirring rods 4 are fixedly connected to the outer surface of the rotating rod 3, and each of the multiple stirring rods 4 is provided with a powder nozzle 401.
[0022] The auxiliary components include an air pump 6, which is fixedly connected to the top of the outer surface of the drum dryer 1. A drying device 7 is fixedly connected to the top of the outer surface of the drum dryer 1. An air supply pipe 601 is provided inside the air pump 6, and the end of the air supply pipe 601 away from the air pump 6 is located inside the drying device 7.
[0023] Through the above technical solution, material is added into the drum dryer 1 through the feed inlet 101. The material is dehydrated by centrifugal force through the rotation of the inner drum 2. During the dehydration process of the inner drum 2, the drive motor 8 is turned on, which drives the rotating rod 3 to rotate. The rotation direction of the rotating rod 3 is opposite to that of the inner drum 2. Dispersant, such as diatomaceous earth or sawdust, is added into the rotating rod 3 through the feed pipe 5. The feed pipe 5 is located inside the rotating rod 3 and is not affected by the rotation of the rotating rod 3. The dispersant is discharged through multiple powder nozzles 401 inside the stirring rod 4 connected to the rotating rod 3. Through the above technical solution, the mechanical crushing of the stirring rod 4 can directly break up peat clumps and destroy the hard shell structure formed by the stickiness of humus. At the same time, the dispersant such as diatomaceous earth and sawdust sprayed through the powder nozzles 401 can form an inert isolation layer on the surface of peat particles, reducing the adsorption force between particles and preventing adhesion and clumping from the source. This keeps the peat material in a loose state, greatly increasing the contact area with the hot air in the drum and making the moisture evaporation path smoother.
[0024] Through the above technical solution, when the drum dryer 1 dehydrates the internal material, the air pump 6 is turned on to extract gas from inside the drum dryer 1. The gas is then transported to the drying device 7 through the air supply pipe 601, where it is dried. The dried gas is then transported to the feed pipe 5 through the return air pipe 701. The dried gas is used to assist in the spraying of dispersant, and it re-enters the drum dryer 1, forming a thermal cycle. Through this technical solution, the air pump 6 can quickly expel the high humidity water vapor inside the drum dryer 1, reducing the internal humidity and creating a low humidity environment. This accelerates the migration of moisture from the peat to the surface. Combined with the drying hot air introduced by the thermal cycle, the circulation is further enhanced, improving the dehydration efficiency and preventing localized over-drying or over-wetting.
[0025] Specifically, the rotating rod 3 is equipped with a feed pipe 5, and the drying device 7 is equipped with a return air pipe 701, with the end of the return air pipe 701 away from the drying device 7 located inside the feed pipe 5.
[0026] With the above technical solution, the feed pipe 5 is set inside the rotating rod 3 and is not affected by the rotation of the rotating rod 3. The dried gas is transported to the inside of the feed pipe 5 through the return gas pipe 701, and the dried gas is used to assist the spraying of the dispersant.
[0027] Specifically, a drive motor 8 is fixedly connected to the bottom of the outer surface of the drum dryer 1, and the output shaft of the drive motor 8 is fixedly connected to the rotating rod 3.
[0028] Through the above technical solution, the rotating rod 3 is driven by the drive motor 8 to rotate, and the rotation direction of the rotating rod 3 is opposite to the rotation direction of the inner cylinder 2.
[0029] Specifically, a feed inlet 101 is fixedly connected to the top of the outer surface of the drum dryer 1.
[0030] The above technical solution allows materials to be added into the drum dryer 1 through the feed inlet 101.
[0031] Specifically, the drum dryer 1 has a liquid outlet 102 and a material outlet 103 inside.
[0032] The above technical solution allows for liquid discharge through outlet 102 and material discharge through outlet 103.
[0033] Specifically, multiple support legs 104 are fixedly connected to the bottom of the outer surface of the drum dryer 1.
[0034] The above technical solution supports the drum dryer 1 via the support leg 104.
[0035] In operation, material is added into the drum dryer 1 through the feed inlet 101. The material is dehydrated by centrifugal force through the rotation of the inner drum 2. During the dehydration process of the inner drum 2, the drive motor 8 is turned on, which drives the rotating rod 3 to rotate. The rotation direction of the rotating rod 3 is opposite to that of the inner drum 2. Dispersant, such as diatomaceous earth or sawdust, is added into the rotating rod 3 through the feed pipe 5. The feed pipe 5 is located inside the rotating rod 3 and is not affected by the rotation of the rotating rod 3. The dispersant is discharged through multiple powder nozzles 401 inside the stirring rod 4 connected to the rotating rod 3. Through the above technical solution, the mechanical crushing of the stirring rod 4 can directly break up peat clumps and destroy the hard shell structure formed by the stickiness of humus. At the same time, the dispersant such as diatomaceous earth and sawdust sprayed through the powder nozzles 401 can form an inert isolation layer on the surface of peat particles, reducing the adsorption force between particles and preventing adhesion and clumping from the source. This keeps the peat material in a loose state, greatly increasing the contact area with the hot air in the drum and making the moisture evaporation path smoother.
[0036] When the material inside the drum dryer 1 is dehydrated, the air pump 6 is turned on to extract gas from inside the drum dryer 1. The gas is then transported to the drying device 7 through the air supply pipe 601. The drying device 7 dries the gas, and the dried gas is then transported to the feed pipe 5 through the return air pipe 701. The dried gas is used to assist in the spraying of dispersant, and the dried gas re-enters the drum dryer 1 to form a thermal cycle. Through the above technical solution, the air pump 6 can quickly expel the high humidity water vapor inside the drum dryer 1, reduce the internal humidity, and create a low humidity environment. This accelerates the migration of moisture from the inside of the peat to the surface. Combined with the drying hot air introduced by the thermal cycle, the circulation is further enhanced, the dehydration efficiency is improved, and local over-drying or over-wetting can be avoided.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
