Description

Technical Field

[0001] This utility model belongs to the field of workshop environmental protection equipment, and in particular relates to an integrated device for feather drying heat recovery and dust purification. Background Technology

[0002] A crucial step in feather processing is drying the washed feathers, a process that consumes a significant amount of heat energy. Before sorting, feathers require high-temperature drying and sterilization. Currently, raw feathers are typically weighed and quantitatively added to the dryer. During drying, steam from a power plant heats the inner wall of the dryer to 170 degrees Celsius. Upon contact with this high-temperature wall, the feathers absorb heat from their ambient temperature, raising their own temperature. Once their moisture content reaches 100 degrees Celsius, it evaporates and is carried out of the dryer by a fan into the exhaust chamber.

[0003] Along with the dust and down entering the exhaust chamber, some of it settles there, while the rest is filtered through activated carbon. During this process, a large amount of heat is released into the atmosphere, resulting in energy waste. Furthermore, the activated carbon needs frequent replacement to remove dust from the exhaust gas. Therefore, this processing method has drawbacks: high energy consumption, frequent maintenance of environmental protection equipment, high material consumption, and significant damage to the raw feathers, thus reducing the quality of the feather products.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Examples, such as Figure 1 , Figure 2 and Figure 3As shown, the integrated device for heat recovery and dust purification in feather drying provided by this utility model includes a manifold 1, a hot water buffer tank 2, and a support system 5. The manifold 1 is used to collect high-temperature steam from the drying fan in the feather processing workshop, which carries dust and some feathers. The hot water buffer tank 2 is used to supply hot water, and its output direction is equipped with a hot water pump 3 and a hot water outlet pipe 4. The hot water buffer tank 2 is also equipped with an inlet pipe 12 for replenishing water. The inlet pipe 12 is equipped with a pneumatic gate, and the temperature and water level are detected by the PLC control system. When the required temperature and water level are reached, water replenishment is activated. The support system 5 is located below the support system 5. Jet pump 6 is connected to hot water outlet pipe 4 or inlet pipe 12 via a pipe. A diversion pipe 7 is provided at the pump outlet end of jet pump 6. A jet jet device 8 and a water-air separator 9 are provided in the conveying direction of the diversion pipe 7. The jet jet device 8 includes a negative pressure end and the negative pressure end is connected to the manifold 1. A vortex air intake device connected to the jet end of the jet jet device 8 is provided in the water-air separator 9. An exhaust port 91 and a drain port 92 are provided on the water-air separator 9. A filter pump 11 and a filter tank 10 connected to the filter pump 11 are provided in the discharge direction of the drain port 92. The outlet side of the filter tank 10 is connected to the hot water buffer tank 2.

[0023] Specifically, in the feather production workshop, after the feathers discharged from the dehydration stage are dried in the dryer, the workshop's energy-saving equipment opens the diversion gate through the control system PLC. The high-temperature and high-heat water vapor in the feathers is transported to the manifold 1 by the drying fan. The jet pump 6 is started, and the high-speed and high-pressure water flow enters the jet spray device 8. The high-temperature water vapor containing dust is fully stirred and mixed with water under the negative pressure of the jet spray device 8. Then, the water containing heat and dust is sprayed into the water-air separation tank 9. The water flow rotates at high speed in the water-air separation tank 9, and the water and air are separated under the action of centrifugal force. Hot water containing heat and dust is stored in a water-air separator 9. The control system, based on the water level, directs the bottom filter pump 11 to the filter tank 10 for filtration and separation. The filtered clean water enters a hot water buffer tank 2, which is equipped with a water level sensor and a temperature transmitter. The production process sets the required temperature, and the PLC control system detects the temperature and water level. When the required temperature is reached, the hot water pump 3 is activated to distribute the hot water through the hot water outlet pipe 4 to the production line in the workshop, providing the necessary hot water for washing down feathers. This hot water has a moderate temperature, which helps reduce damage and loss of feathers and ensures feather quality. In this way, the waste gas is collected and treated through the combined action of the manifold 1, the jet spray device 8, and the water-air separator 9. The waste gas undergoes heat exchange with the jet water flow and is purified, resulting in clean gas emissions that meet standards. Dust is also carried by the hot water to the filter tank 10 for filtration. The filtered hot water then enters the hot water buffer tank 2 for recycling, thus achieving heat recovery and dust treatment, achieving the dual goals of energy saving, emission reduction, and environmental protection.

[0024] To ensure cleaner separated gas, the diversion pipe 7 provided by this invention branches into two branches: a jet pipe 71 and a spray pipe 72. The jet pipe 71 is connected to a jet spray device 8, and the water-gas separator 9 is equipped with a spray device connected to the spray pipe 72. The spray device is used to perform secondary treatment on the gas inside the water-gas separator 9. In this way, by performing secondary treatment on the gas after cyclone separation, including secondary dust removal and secondary heat recovery, the gas discharged from the exhaust port 91 becomes low-temperature clean gas, which is then discharged from the exhaust port 91 in compliance with environmental standards. Therefore, this equipment has a good treatment capacity for the waste gas of the feather processing workshop, which is in line with the concept of environmentally friendly production.

[0025] In order to improve the utilization rate of the filtration system of this equipment, the filter tanks 10 provided by this utility model are arranged in pairs and in parallel on the support system 5, one for use and one for backup. This ensures that while the equipment is lifting one filter tank 10 to clean up the waste residue, another filter tank 10 can remain in working condition, thereby ensuring that the hot water entering the hot water buffer tank 2 is filtered water.

[0026] To better connect with the drying equipment in the workshop, a manifold 1 is used as the gas collection pipe, and multiple branch pipes 1a are installed on the manifold 1. Each branch pipe 1a corresponds to a pipe in the drying workshop. A diversion gate 1b is installed at the inlet of the branch pipe 1a. By opening the diversion gate 1b through the control system PLC, the actual flow rate entering the manifold 1 can be controlled, and the reasonable allocation and control of different lines can be realized.

[0027] To improve the practicality of the filter tank 10, the filter tank 10 provided by this utility model is equipped with a filter screen for filtering feathers and dust, and a slag discharge gate is provided at the bottom of the filter tank 10. Hot water is filtered through the filter screen, and the filtered waste residue can be discharged periodically from the slag discharge gate.

[0028] Furthermore, the filter tank 10 is equipped with a brushing device for cleaning the filter screen. The working surface of the filter screen is a conical surface, and the brushing path of the brushing device is also a conical surface. The brushing device is driven by a motor, and the working surface of the brushing device corresponds to the filter surface of the filter screen. The brush is rotated to clean the filter screen by PLC control. A slag discharge gate is provided at the bottom to periodically discharge the filtered dust and impurities.

[0029] To improve the practicality of the support system 5, the support system 5 provided by this utility model is a steel frame system and includes at least an upper layer 51, a middle layer 52, and a lower layer 53. The manifold 1 is located on the upper layer 51, the filter tank 10 and the jet spray device 8 are located on the middle layer 52, the water-air separator 9 runs through the middle layer 52 and the lower layer 53, and the hot water buffer tank is located on the lower layer 53. A staircase 54 is provided between the lower layer 53 and the middle layer 52, and a guardrail 55 is provided around the middle layer 52. The support system 5 provides ample vertical installation space for the water-air separator 9, allowing the larger vertically tall water-air separator 9 to have a sufficiently long swirling separation path for better water-air separation. The filter tank 10 provides filtered water to the hot water buffer tank 2 from top to bottom, which helps improve the output efficiency of the filtered water. The staircase 54 facilitates workers' access to and from the support system 5 for daily maintenance and repair. The guardrail 55 ensures the safety of workers walking on the support system 5.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
