[0019] The embodiment of the present application achieves the purpose of adjusting the steam dryness of the key silk-making process by providing a steam spray device for the key silk-making process, and provides equipment support for studying the impact of steam with different dryness gradients on the key silk-making process. Example

[0020] The overall idea of the technical solution in the embodiments of this application is as follows:

[0021] like Figure 1-3 As shown, in the key silk-making process of the tobacco industry, the dryness of steam has an important impact on the quality of tobacco. In order to deeply study the influence of steam dryness gradient on the key silk-making process, we have developed a steam spray device for the key silk-making process. This embodiment will introduce in detail the structure, working principle, installation and commissioning, operation method, maintenance, possible faults and solutions of the device, so as to better understand and apply the device. The utility model provides a steam spray device for the key silk-making process, including a water tank 1, a flexible joint 2, a variable frequency water pump 3, a check valve 4, a spray hose 5, an atomizing nozzle 6, a water pump base 7 and a skid-mounted base 8.

[0022] Water tank 1 is the water storage part of the entire device. It is made of stainless steel and has good corrosion resistance and sealing. Its capacity is designed according to actual production needs and can usually meet the water consumption of steam spraying within a certain period of time. A water level monitoring device is installed inside the water tank 1. When the water level is lower than the set value, an alarm signal will be issued to remind the operator to replenish distilled water in time.

[0023] The flexible joint 2 is made of rubber and is connected to the outlet of the water tank 1. Its main function is to reduce the vibration transmission between the water tank 1 and the subsequent pipeline, reduce the vibration and noise during equipment operation, and at the same time compensate for the installation deviation and thermal expansion and contraction of the pipeline to a certain extent.

[0024] The variable-frequency water pump 3 is the core power component of the system, responsible for pumping distilled water from the water tank 1 and delivering it to the subsequent pipeline. This pump utilizes advanced variable-frequency technology, automatically adjusting its operating frequency based on the desired atomized water volume, thereby achieving precise flow control. Pressure sensors are installed at both the pump's inlet and outlet to monitor operating pressure and ensure it operates within a safe range.

[0025] Check valve 4 is installed at the outlet of variable frequency water pump 3 to prevent atomized water in the pipeline from flowing back into the water pump, protecting the water pump from damage. The valve core of check valve 4 is made of high-quality stainless steel, which has excellent sealing performance and corrosion resistance, ensuring that it will not leak during long-term use.

[0026] The spray hose 5 is made of a high-temperature, corrosion-resistant, flexible material, such as polytetrafluoroethylene. Its function is to transport distilled water from the check valve 4 to the atomizing nozzle 6. The length and diameter of the spray hose 5 are selected based on actual installation requirements to ensure flexible placement without affecting water flow.

[0027] The atomizing nozzle 6 is a key component for achieving steam atomization. It utilizes advanced atomization technology to evenly atomize distilled water into fine droplets and spray them into the steam pipeline. The atomizing effect of the atomizing nozzle 6 can be adjusted by adjusting the nozzle's internal structure or external control parameters to meet different steam dryness requirements.

[0028] The water pump base 7 is made of a sturdy metal material, such as cast iron or cast steel. Its primary function is to provide stable mounting support for the variable frequency water pump 3, ensuring that the water pump does not wobble or shift during operation. Bolt holes are provided on the base for securing the water pump to the base.

[0029] The skid-mounted base 8 is the fundamental support structure for the entire system. It is constructed from welded channel steel and steel plates. It not only supports the weight of the water tank, water pump, and other equipment, but also facilitates the overall transport and installation of the system. The surface of the skid-mounted base 8 is treated with rust prevention to extend its service life.

[0030] Preparation before installation: Check the integrity and appearance quality of each component of the device to ensure that there are no damaged, deformed or missing parts. Prepare the tools and equipment required for installation, such as wrenches, screwdrivers, cranes, etc. Determine the installation location. It should be selected in a well-ventilated place that is convenient for operation and maintenance, and ensure that there is enough space around the device.

[0031] The steps for device installation are as follows:

[0032] 1. Place the skid-mounted base 8 in the predetermined position and secure it with anchor bolts to ensure that the base is stable and firm.

[0033] 2. Install the water tank 1 on the skid-mounted base 8, connect it with bolts, and ensure that the horizontality and verticality of the water tank 1 meet the requirements;

[0034] 3. Install the variable frequency water pump 3 and the water pump base 7, fix the water pump to the base with bolts, and then weld the base to the skid-mounted base 8. Note that the inlet and outlet directions of the water pump should be consistent with the direction of the pipeline connection;

[0035] 4. Connect the pipes between the water tank 1 and the variable frequency water pump 3, including the flexible joint 2 and the check valve 4. Ensure that the pipes are tightly connected and leak-free.

[0036] 5. Install the spray hose 5 and the atomizing nozzle 6. Connect one end of the spray hose 5 to the outlet of the check valve 4 and the other end to the atomizing nozzle 6. Note that the arrangement of the spray hose 5 should avoid excessive bending and stretching.

[0037] According to the electrical schematic diagram of the device, connect the variable frequency water pump 3, water level monitoring device and other electrical equipment to the control system, check the correctness and firmness of the electrical connections, ensure there are no short circuits, open circuits and other faults, perform grounding protection, and ensure safe operation of the equipment.

[0038] Working Principle: When steam dryness needs to be adjusted during a critical silk-making process, the steam atomization device is activated. Driven by electricity, variable-frequency water pump 3 begins operating, drawing distilled water from tank 1. Based on parameters such as the preset atomized water volume and real-time steam flow monitoring, variable-frequency water pump 3 automatically adjusts its operating frequency to control the pumping flow and pressure.

[0039] The extracted distilled water passes through flexible joint 2 and check valve 4 and enters spray hose 5. Transported by spray hose 5, the distilled water reaches atomizing nozzle 6. Atomizing nozzle 6 utilizes its special internal structure and pressure differential to atomize the distilled water into fine droplets, which are then sprayed into the steam pipeline at a specific speed and angle.

[0040] Distilled water droplets evaporate rapidly in the steam pipeline, absorbing heat from the steam, thereby lowering the steam temperature and increasing its dryness. By precisely controlling the atomization volume and injection speed of the distilled water, the steam dryness can be precisely adjusted to meet the steam quality requirements of different silk-making processes.

[0041] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
