Description

Technical Field

[0001] The utility model belongs to the technical field of material drying, in particular to a rapid drying device. Background Art

[0002] Animal manure, such as chicken and pig manure, is rich in nutrients and trace elements, making it an excellent organic fertilizer. Developing compound organic fertilizer from animal manure not only turns waste into treasure, but also reduces environmental pollution and prevents the spread of disease, offering significant economic and social benefits.

[0003] However, the original livestock and poultry manure has a high water content, and sewage is generated during the stacking and transportation process, and there is a risk of large-scale scattering, which affects the environment. Therefore, it is necessary to design a livestock and poultry manure drying equipment.

[0004] The conventional rotary dryer used in organic fertilizer plants is used for drying. However, this type of dryer has a large floor space, high cost, short residence time and relatively poor drying effect.

[0005] Chinese Patent 202321990804.1 provides a new drum dryer, which has a cylinder mounted on a base and a single-layer inner cylinder disposed inside the cylinder. The feed device includes a lifting plate connected to the end of the cylinder, and a lifting plate disposed within the lifting plate. A feed port is disposed on the outer side of the lifting plate, which is vertically disposed and extends through the lifting plate. The device is equipped with a hot air conveying device that blows hot air into the material for drying. However, during the rotation of the cylinder, the material continues to move to one side and eventually accumulates at the rear of the device, preventing uniform distribution of the material within the cylinder.

[0006] Therefore, the present application aims to develop a device that is small in size, movable, has good drying effect, and can be used for drying livestock and poultry manure in a single farm. Utility Model Content

[0007] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a rapid drying device to solve the above-mentioned problems.

[0008] To achieve the above-mentioned purpose, the utility model discloses a rapid drying device, comprising:

[0009] The feeding and discharging system includes a feeding port, a discharging port and an outer cylinder. The outer cylinder is provided with a drying system and a heating system. The feeding port and the discharging port are respectively connected to the drying system.

[0010] The drying system includes an inner drum and a driving device for driving the inner drum to rotate, wherein the driving device drives the inner drum to rotate so that the material continuously moves toward the rear of the equipment; and further includes a return drum arranged in the inner drum for continuously moving the material at the rear of the equipment toward the head of the equipment;

[0011] A heating system, wherein the heating system is used to heat the material in the drying system;

[0012] When the material enters the inner cylinder through the feed port, the driving device drives the inner cylinder to rotate, and the heating system heats and dries the material.

[0013] Compared with the prior art, the present application has the following effects: first, the material enters the inner cylinder of the drying system through the feed port; then, the heating system works to heat the drying system, and then heats the material in the inner cylinder. At the same time, the driving device drives the inner cylinder to rotate to move the material toward the tail of the equipment, so as to achieve uniform heating of the material. After the material moves to the tail of the equipment, the material is continuously moved toward the head of the equipment by the return cylinder. In this way, the back and forth movement of the material avoids the accumulation of the material at the tail of the equipment, which causes uneven heating and drying and low drying efficiency. In summary, the drying equipment designed in the present application is small in size, movable, and has good drying effect, and can be used for drying livestock and poultry manure in a single farm.

[0014] Furthermore, the drying system also includes a first spiral material guiding shovel and a material turning shovel arranged on the inner wall of the inner cylinder. The first spiral material guiding shovel is used to continuously move the material to the rear of the equipment, and the material turning shovel is used to stir-fry the material.

[0015] Furthermore, the material turning and lifting plate is designed as an L-shaped structure, and the angle of the L-shaped structure is 90-120 degrees.

[0016] Furthermore, a breaking chain for breaking up materials is installed on the inner wall of the inner cylinder.

[0017] Furthermore, a crushing cylinder for breaking up materials is also provided in the inner cylinder.

[0018] Furthermore, the crushing barrel includes a connecting rod, a crusher, a supporting circular tube and a supporting transverse tube. The supporting circular tube and the supporting transverse tube are connected to each other. The supporting transverse tube is installed on the inner wall of the inner barrel through the connecting rod.

[0019] Furthermore, the tail of the return barrel is provided with an opening for allowing materials at the tail of the equipment to enter, and the inner wall of the return barrel is provided with a second spiral material guide scooping plate installed in the opposite direction to the first spiral material guide scooping plate, so that the material can be moved to the head of the equipment through the second spiral material guide scooping plate.

[0020] Furthermore, the return barrel adopts a truncated cone design with a small tail and a large head.

[0021] Furthermore, the feed port and the discharge port are both arranged at the head of the equipment.

[0022] Furthermore, it also includes an exhaust gas waste heat utilization pipeline, one end of the exhaust gas waste heat utilization pipeline is connected to the outer cylinder, and the other end is connected to the inner cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1-4As shown, the utility model discloses a rapid drying device, comprising:

[0032] The feeding and discharging system includes a feeding port 1, a discharging port 3 and an outer cylinder 9. The outer cylinder 9 is provided with a drying system and a heating system. The feeding port 1 and the discharging port 3 are respectively connected to the drying system;

[0033] The drying system includes an inner drum 10 and a driving device for driving the inner drum 10 to rotate. When the driving device drives the inner drum 10 to rotate, the material is continuously moved toward the rear of the equipment. It also includes a return drum 17 arranged in the inner drum 10 for continuously moving the material at the rear of the equipment toward the front of the equipment. The return drum 17 is mounted on the inner wall of the inner drum 10 through connecting ribs 15.

[0034] Heating system: the heating system is used to heat the materials in the drying system;

[0035] When the material enters the inner cylinder 10 through the feed port 1, the driving device drives the inner cylinder 10 to rotate, and the heating system heats and dries the material.

[0036] Among them, the outer tube 9 is installed on the ground through the column support 19 and a panel reinforcement rib 20 is provided at the tail. The feed port 1 is installed on the outer tube 9 through the end cover 4 and the connecting channel steel 5. The feed port 1, the end cover 4 and the inner tube 10 are connected to each other, thereby ensuring that the material from the feed port 1 can enter the inner tube 10.

[0037] The drive device includes a drive motor 24, a reducer 23, a connecting gear 22, and a rotating connecting shaft 21. The drive motor 24 is connected to one end of the inner cylinder 10 through the reducer 23, the connecting gear 22, and the rotating connecting shaft 21. The other end of the inner cylinder 10 is rotatably connected to the roller 7 via the track channel 6. The roller 7 is mounted on the outer cylinder 9 via the support plate 8. When the drive motor 24 drives the rotating connecting shaft 21 to rotate, the inner cylinder 10 can rotate in both clockwise and counterclockwise directions.

[0038] Compared with the prior art, the present application has the following effects: first, the material enters the inner cylinder 10 of the drying system through the feed port 1; then, the heating system works to heat the drying system, and then heats the material in the inner cylinder 10. At the same time, the driving device drives the inner cylinder 10 to rotate to move the material toward the tail of the equipment, so as to achieve uniform heating of the material. After the material moves to the tail of the equipment, the material is continuously moved toward the head of the equipment by the return cylinder 17. In this way, the back and forth movement of the material avoids the accumulation of the material at the tail of the equipment, which causes uneven heating and drying and low drying efficiency. In summary, the drying equipment designed in the present application is small in size, movable, and has good drying effect, and can be used for drying livestock and poultry manure in a single farm.

[0039] Continuing with the above embodiment, more specifically, the drying system further includes a first spiral guide scoop plate 12 and a flipper scoop plate 14 disposed on the inner wall of the inner drum 10. The first spiral guide scoop plate 12 is used to continuously move the material toward the rear of the equipment, while the flipper scoop plate 14 is used to stir the material. When the inner drum 10 rotates clockwise, both the first spiral guide scoop plate 12 and the flipper scoop plate 14 rotate with the inner drum 10. Consequently, the material within the inner drum 10 is continuously moved toward the rear of the equipment under the guidance of the first spiral guide scoop plate 12. Once the material reaches the middle of the equipment, the flipper scoop plate 14 continuously lifts and lowers the material, thereby ensuring uniformity of the material and increasing its contact area with the high-temperature exhaust gas.

[0040] More preferably, Figure 4 As shown, the material turning and lifting plate is designed as an L-shaped structure, and the angle of the L-shaped structure is 90-120 degrees. The reason for choosing the angle of 90-120 degrees is to achieve a better turning effect. If the angle is less than 90 degrees, the material will easily get stuck in the angle during the turning process. If the angle is greater than 120 degrees, the range of scattering of the turned material will be small, and the turning effect will be poor. Therefore, the present application adopts a 90-120 degree angle, which not only allows the material to have a larger scattering range, but also ensures a certain amount of material holding.

[0041] Continuing from the above embodiment, it is more preferred that a breaking chain 13 for breaking up the materials is installed on the inner wall of the inner cylinder 10 .

[0042] Continuing with the above embodiment, it is more preferred that a crushing cylinder 16 for breaking up materials is further provided in the inner cylinder 10 .

[0043] Among them, if the material has high viscosity and forms agglomerates or lumps, it will come into contact with the rotating breaking chain 13 and the breaking barrel 16 during the rotation process, and thus be broken up.

[0044] Following the above embodiment, more specifically, Figure 2 As shown, the crushing drum 16 includes a connecting rod 161, a crusher 162, a supporting circular tube 163, and a supporting transverse tube 164. The supporting circular tube 163 and the supporting transverse tube 164 are interconnected. The supporting transverse tube 164 is mounted on the inner wall of the inner drum 10 via the connecting rod 161. The crushers 162 are respectively provided on the inner and outer walls of the supporting transverse tube 164. During the rotation of the inner drum 10, the material comes into contact with the crushers 162 and is broken up. The crushers 162 can be made of either φ10 mm circular tubes or 5 mm steel plates, and are arranged every 100 mm.

[0045] The breakers 162 utilize a triangular plate design with a 120° angle. These breakers are positioned every 200-300 mm along the cylinder to break up clumped material. A break-up chain 13 is also provided to knock down material adhering to the cylinder wall, preventing it from clumping and ensuring it remains free of debris, thereby enhancing heat transfer.

[0046] It should be noted that the material breaker 162 and the breaking chain 13 can not only crush the material but also stir the material, and the breaking chain 13 will hit the cylinder wall during the rotation process, breaking up the attachments by vibration, cleaning the cylinder wall and improving the heat transfer efficiency.

[0047] Following the above embodiment, more specifically, Figure 3 As shown, the rear end of the return barrel 17 is provided with an opening 171 for admitting material from the rear end of the equipment. A second spiral guide scoop 172, mounted in the opposite direction to the first spiral guide scoop 12, is installed on the inner wall of the return barrel 17. This second spiral guide scoop 172 allows the material to move toward the front end of the equipment. After the material from the rear end of the equipment enters the return barrel 17 through opening 171, the return barrel 17 rotates. Guided by the second spiral guide scoop 172, the material entering the return barrel 17 continuously moves from the rear end of the equipment toward the center, thereby achieving back-and-forth movement within the inner barrel 10. This prevents the problem of material accumulation at the rear end of the equipment, which can lead to uneven drying and low drying efficiency, as is common in the prior art. In other words, without changing the rotational direction of the inner barrel 10, the material at the rear end of the equipment can be moved toward the front end, preventing material accumulation and increasing the heated surface area, thereby improving drying efficiency.

[0048] Specifically, the return barrel 17 adopts a frustum-shaped design with a small tail and a large head. The material can be returned from the tail to the middle through the inclined barrel wall and the second spiral material guide plate 172 which is completely opposite to the barrel wall. The angle of the opening 171 at the tail of the return barrel 17 can be 180° to ensure that most of the material can fall into the barrel.

[0049] Continuing with the above embodiment, it is more preferable that both the feed port 1 and the discharge port 3 be located at the head of the device. Because the majority of the material is concentrated in the middle and rear portions of the device during the turning process, if the discharge port 3 is located at the rear portion, the material still being dried will fall into the discharge port 3. Furthermore, this is not convenient due to the space constraints of the drive device located at the rear portion. It should be noted that when the inner drum 10 rotates counterclockwise, the material continuously moves from the rear portion of the device to the head portion, and is then discharged from the discharge port 3 at the head portion.

[0050] Continuing with the above embodiment, it is more preferred that the exhaust gas waste heat utilization pipe 11 be further included, one end of the exhaust gas waste heat utilization pipe 11 being connected to the outer cylinder 9 and the other end being connected to the inner cylinder 10. The exhaust gas waste heat utilization pipe 11 transfers the heat of the combustion exhaust gas into the inner cylinder 10 for reuse, thereby improving thermal efficiency.

[0051] Continuing with the above embodiment, the heating system includes a combustion chamber. Specifically, the bottom of the inner tube 10 is a combustion chamber, and a combustion grate 18 is provided in the combustion chamber. The height of the combustion grate 18 can be adjusted to always keep the outer flame heating the inner tube 10, thereby improving the heat utilization rate. A 5mm hole is opened at the bottom of the combustion grate 18. During the combustion process, a negative pressure is formed in the combustion chamber, and the atmospheric pressure can press air into the combustion chamber to assist combustion. Therefore, an air blower is not required, thereby reducing the energy consumption of the equipment. Among them, the combustion grate 18 adopts a design structure of main pipe + branch pipe, and the ignition heads are cross-distributed. During the combustion process, the combustion of biogas generates negative pressure, and the atmospheric pressure presses air into the combustion chamber to assist combustion, thereby solving the problem of the combustion-supporting blower. At the same time, the outer flame of the flame directly burns the wall of the inner tube 10, and the high temperature is transferred to the internal material through the wall. Compared with hot air drying, the heat transfer efficiency is improved.

[0052] Continuing with the above embodiment, it is more preferred that a steam induced draft fan 2 is further included, which draws steam and odor from the inner drum 10 during the drying process to an external water tank, where the steam and odor are absorbed by the liquid in the water tank to achieve odorlessness.

[0053] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
