Description

Technical Field

[0001] This utility model relates to the field of shrimp feed manufacturing, and in particular to a shrimp feed drying device. Background Technology

[0002] Shrimp feed drying technology mainly revolves around efficient dehydration, nutrient retention, and cost control. Existing methods include: 1) hot air drying, which directly evaporates moisture through high-temperature airflow and has simple equipment; 2) fluidized bed drying, which uses high-speed airflow to suspend the material and has high heat transfer efficiency; 3) microwave drying, which heats rapidly through molecular vibration and has a fast drying speed; 4) vacuum drying, which lowers the boiling point under negative pressure and reduces nutrient loss; and 5) freeze drying, which uses ice crystal sublimation to dehydrate and has the best quality but is extremely expensive.

[0003] The existing application number 202320671928.7 discloses a shrimp and crab feed drying and dehumidification device. The feed raw materials to be processed are poured into the inside of the device body through the feed pipe. The heating tube is used to dry the feed. The drive motor is used to drive the stirring rod to rotate, so that the feed raw materials can be heated evenly.

[0004] However, the above technologies have the following problems:

[0005] A large amount of shrimp feed is concentrated inside the main body of the device. Heating rods installed inside the main body heat the piled shrimp feed on the outside. This can cause the clumps of shrimp feed to be constantly stirred in the middle by the stirring mechanism, resulting in uneven heat distribution inside and outside the device. This leads to uneven heating of the shrimp feed and affects the overall qualified rate of shrimp feed preparation.

[0006] Large quantities of shrimp feed require prolonged mixing, heating, and drying, followed by the need to pause the equipment for loading and unloading, making the operation cumbersome and the drying efficiency low.

[0007] Therefore, a shrimp feed drying device is needed. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a shrimp feed drying device to solve the problems of uneven drying and low efficiency.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a shrimp feed drying device, including a water storage tank, a shrimp feed drying pipe installed inside the water storage tank, the shrimp feed drying pipe being arranged in a spiral shape, the upper input end of the shrimp feed drying pipe being located at the upper end of the water storage tank, the lower output end of the shrimp feed drying pipe being located at the lower end of the water storage tank, an inner heating layer being installed inside the shrimp feed drying pipe, the shrimp feed being input from the upper end of the shrimp feed drying pipe, continuously dried by the spiral inner heating layer, and finally discharged from the lower output end of the shrimp feed drying pipe.

[0010] Furthermore, the shrimp feed drying tube includes an outer metal layer, an inner insulation layer is provided inside the outer metal layer, an inner heating layer is located inside the inner insulation layer, and an inner metal layer is also provided inside the inner heating layer, and the shrimp feed rolls in the inner metal layer.

[0011] Furthermore, an inlet bend is installed at the upper end of the shrimp feed drying pipe, and the inlet bend is fixedly welded to the upper end of the water storage tank. An outlet bend is installed at the lower end of the shrimp feed drying pipe, and the output end of the outlet bend is fixedly welded to a flange installed on the lower side of the water storage tank.

[0012] Furthermore, a flow guiding component is installed at the upper end of the feed bend, and a fan is installed at the upper end of the flow guiding component. The fan blows air into the flow guiding component and enters the shrimp feed drying pipe through the feed bend. The flow guiding component includes a vertical pipe and an inclined pipe welded to one side of the vertical pipe.

[0013] Furthermore, the inner side of the water storage tank is hollow, and the hollow inner cavity stores clean water. The shrimp feed drying pipe is submerged in the middle of the clean water. A water inlet pipe is welded to the upper end of the water storage tank, and a water outlet pipe is welded to one side of the lower end of the water storage tank. A temperature monitoring assembly is installed in the middle of the upper end of the water storage tank. Temperature sensor 1, temperature sensor 2, and temperature sensor 3 are also wired to the temperature monitoring assembly. Temperature sensor 1, temperature sensor 2, and temperature sensor 3 are installed in the upper, middle, and lower positions of the water storage tank, respectively. The detection ends of temperature sensor 1, temperature sensor 2, and temperature sensor 3 are inserted into the clean water inside the water storage tank.

[0014] Compared with the prior art, the beneficial effects of this utility model include:

[0015] Shrimp feed is fed into the vertical pipe through a shrimp feed pipeline conveying device, and then enters the inner metal layer through the feed bend. As the pelleted shrimp feed rolls down from the spiral inner heating layer, it is heated and dried by the inner heating layer. At the same time, the fan discharges the dried water vapor from the flange head, and the pelleted shrimp feed is also discharged from the flange head, completing the drying of the pelleted shrimp feed. Not only can a small amount of pelleted shrimp feed be quickly rolled down from the inner heating layer and dried evenly, but there is also no need to stop the machine for loading and unloading, resulting in high working efficiency and good drying effect.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] According to one embodiment of the present invention, in conjunction with Figures 1-3The diagram shows a shrimp feed drying device, including a water storage tank 1. A shrimp feed drying pipe 9 is installed inside the water storage tank 1. The input end of the shrimp feed drying pipe 9 is connected to the output end of a shrimp feed pipeline conveying device via a flange. The output end of the shrimp feed drying pipe 9 is located at the lower outer side of the water storage tank 1. Particle shrimp feed is conveyed from the shrimp feed pipeline conveying device to the input end of the shrimp feed drying pipe 9, dried through the shrimp feed drying pipe 9, and then discharged from the output end of the shrimp feed drying pipe 9, thus completing the drying of the particle shrimp feed.

[0026] Combination Figure 1 As shown, a ladder 2 is installed on one side of the water tank 1 by screws, and a guardrail 21 is installed at the upper edge of the water tank 1. The upper end of the ladder 2 is connected to the guardrail 21 by screws, which makes it convenient for operators to climb to the upper end of the water tank 1 via the ladder 2 to inspect and clean the equipment.

[0027] Combination Figures 1-2 As shown, the inner side of the water storage tank 1 is hollow, and the hollow cavity stores clean water. The shrimp feed drying pipe 9 is submerged in the middle of the clean water. Because water has a high specific heat capacity, a unit mass of water can absorb and store more heat. When the outside of the pipe is covered with clean water, the clean water can form a heat insulation buffer layer, effectively slowing down the rate at which heat is transferred to the outside. In contrast, if the pipe is in direct contact with the outside air, the air will quickly carry away the heat from the pipe through forced convection, and the heat preservation effect is far less than that of water covering. In addition, when the drying device is finally shut down, the clean water absorbs the heat from the pipe and becomes warm water, which is supplied to other auxiliary equipment or workers that require warm water, realizing the recovery and reuse of heat energy.

[0028] It should be added that a water inlet pipe 4 is welded to the upper end of the water storage tank 1, through which water can be added to the water storage tank 1. A water outlet pipe 5 is welded to one side of the lower end of the water storage tank 1, through which clean water at a certain temperature can be discharged for recycling.

[0029] It should be further noted that the clean water is low-temperature water, which is preferentially heated and then kept at a constant temperature through the shrimp feed drying pipe 9. The shrimp feed drying temperature is 80-110 degrees Celsius. Alternatively, high-temperature water can be directly input from the water inlet pipe 4, and then the high-temperature water directly heats the shrimp feed drying pipe 9 through the water storage tank 1, and is finally discharged from the water outlet pipe 5, thus achieving the drying effect of the pelleted shrimp feed.

[0030] Furthermore, a temperature monitoring assembly 3 is installed in the upper middle part of the water storage tank 1, and the water inlet pipe 4 is located on one side of the temperature monitoring assembly 3. The temperature monitoring assembly 3 can monitor the stability of the water inside the water storage tank 1. If the water temperature inside the water storage tank 1 is abnormally high, the staff can drain the clean water or use an underwater camera to check whether the outside of the shrimp feed drying pipe 9 is damaged.

[0031] Furthermore, to improve detection accuracy, temperature sensors 31, 32, and 33 are connected to the temperature monitoring assembly 3 by wires. Temperature sensors 31, 32, and 33 are installed at the top, middle, and bottom of the water tank 1 by screws. The detection ends of temperature sensors 31, 32, and 33 are inserted into the clean water inside the water tank 1. By detecting the temperature of the clean water at different locations, the detection effect and the pre-judgment of the inspection point are improved.

[0032] Combination Figures 3-4 As shown, the shrimp feed drying pipe 9 is spirally arranged with a hollow inner cavity. The shrimp feed drying pipe 9 is made of multiple spiral pipe sections welded together. Each section of the shrimp feed drying pipe 9 consists of an outer metal layer 91, an inner insulation layer 92, an inner heating layer 93, and an inner metal layer 94. The inner insulation layer 92 fills the inside of the outer metal layer 91. The inner heating layer 93 is installed inside the inner insulation layer 92. The inner metal layer 94 is installed inside the inner heating layer 93. The inner heating layers 93 on the inner sides of two adjacent sections of the shrimp feed drying pipe 9 are electrically connected. When the granular shrimp feed rolls down from the spiral inner heating layer 93, it is heated and dried by the inner heating layer 93. The spiral arrangement not only increases the length of the pipe and ensures the drying time, but also has a small footprint and high practicality. At the same time, the added inner insulation layer 92 can also play a role in heat preservation.

[0033] Combination Figure 1 , Figure 3 as well as Figure 5 As shown, the upper end of the shrimp feed drying pipe 9 is detachably equipped with an inlet bend 8, which is fixedly welded to the upper end of the water storage tank 1. The lower end of the shrimp feed drying pipe 9 is detachably equipped with an outlet bend 10, the output end of which is fixedly welded to a flange head 101 installed on the lower side of the water storage tank 1. The detachable connection can be installed with screws or clips. It should be noted that the detachable connection must ensure the sealing after installation.

[0034] Combination Figure 1 , Figure 3 as well as Figure 5 As shown, a flow guide component 7 is installed at the upper end of the feed bend 8, and a fan 6 is installed at the upper end of the flow guide component 7. The fan 6 blows air into the flow guide component 7 and enters the shrimp feed drying pipe 9 through the feed bend 8. Under normal drying conditions, the fan 6 operates at a low speed, which can discharge the drying water vapor from the flange 101. When it is found that the discharge from the flange 101 is small or almost non-existent, the fan 6 can be increased to discharge the granular shrimp feed that is blocked in the shrimp feed drying pipe 9 through air pressure.

[0035] Furthermore, combined Figure 5As shown, the flow guiding component 7 includes a vertical pipe 71 and an inclined pipe 72 welded to one side of the vertical pipe 71. The inclined pipe 72 is connected to the output end of the shrimp feed pipeline conveying device. The shrimp feed conveyed from the inclined pipe 72 should preferably not fill the entire inner cavity of the inclined pipe 72, so that the shrimp feed will not be blocked. Moreover, since the diameter of the inclined pipe 72 is smaller than the diameter of the vertical pipe 71, the shrimp feed discharged from the inclined pipe 72 will not fill the entire vertical pipe 71, so that the amount of shrimp feed entering from the vertical pipe 71 is moderate, which makes it easy for the feed to roll down from the inside of the spiral shrimp feed drying pipe 9, ensuring stable conveying and more uniform heating.

[0036] Furthermore, the upper end of the vertical pipe 71 is fixedly connected to the output end of the blower 6 by screws, and the lower end of the vertical pipe 71 is fixedly connected to the input end of the feed bend 8 by screws.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
