Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-temperature drying equipment, and in particular to a large-scale low-temperature drying device for cow dung modified with biological desiccant. Background Technology
[0002] In the field of treating cow manure modified with biological desiccant, the drying efficiency and quality of cow manure directly affect the effectiveness of subsequent resource utilization.
[0003] Traditional cow dung drying processes often suffer from insufficient moisture filtration during pretreatment, leading to high energy consumption and low efficiency. For example, directly introducing insufficiently dehydrated cow dung into the drying process increases the load on the drying equipment, prolongs drying time, and easily results in uneven drying. Furthermore, existing low-temperature drying equipment has shortcomings in the coordination between material transport and drying. Traditional transport methods easily lead to material accumulation and poor conveying, especially in large-scale processing scenarios, making it difficult to achieve a continuous and stable production process. Meanwhile, high-temperature drying processes may destroy the active components of biological desiccants in cow dung, affecting its functional application value. Existing low-temperature drying equipment lacks efficient design in matching material transport with the low-temperature environment, resulting in inconsistent drying quality. Therefore, these issues need to be discussed. Utility Model Content

[0021] Working Principle: When using this invention, power is supplied to the device, and cow dung is poured in from the top of the protective cover 1. The first stepper motor 5 and the second stepper motor 4 are started. The cow dung reaches the top of the first filter conveyor belt 2. Since cow dung is not all dry, the moisture content will be pushed through the first filter conveyor belt 2 by gravity to the first collection platform 7. Because the first collection platform 7 is inclined, the moisture inside will be discharged along the first collection platform 7. The cow dung transported by the first filter conveyor belt 2 will reach the conveyor belt 20. Under the transport of the conveyor belt 20, when the cow dung reaches the stop plate 21, the second stepper motor 4 is turned off and the first electric pusher cylinder 3 is started to drive the extrusion block 22 to extrude the cow dung. The squeezed cow manure, containing moisture, passes through the filter screen 18 to the second collection platform 8 and is then discharged. The first electric pusher cylinder 3 retracts, and the second stepper motor 4 is activated, thus completing the cycle. The second electric pusher cylinder 6 is then activated, driving the pusher block 23 to push the squeezed cow manure from the squeeze platform 19 into the transport pipe 10. The cow manure passes through the transport pipe 10 into the low-temperature drying chamber 9. Low-temperature gas is introduced into the low-temperature air inlet pipe 12 to circulate with the low-temperature exhaust pipe 11. The third stepper motor 15 and the fourth stepper motor 14 are then activated. The cow manure in the low-temperature drying chamber 9 passes through the second filter conveyor belt 16 and the third filter conveyor belt 17, and finally reaches the collection box 13.
