Description

Technical Field

[0001] This utility model relates to the field of plate cleaning technology, and more specifically, to a plate cleaning device. Background Technology

[0002] Plate heat exchangers, as compact and efficient heat exchange devices, are widely used in various industries such as metallurgy, petroleum, pharmaceuticals, shipbuilding, textiles, chemicals, medicine, and food. Their core components consist of heat transfer plates made of thin metal plates (usually stainless steel). These plates are pressed into corrugated heat exchange plates of a specific shape and stacked with sealing gaskets to create a highly efficient heat exchange structure. However, due to the narrow internal flow orifice of plate heat exchangers and the unique channels through which hot and cold media flow sequentially between adjacent heat exchange plates during operation, scaling is highly likely to occur.

[0003] Scale buildup not only reduces or even completely blocks the internal channels of plate heat exchangers, severely impacting heat exchange efficiency and threatening smooth production and safe equipment operation, but also increases energy consumption and maintenance costs. Therefore, regularly cleaning the plates of plate heat exchangers to remove scale is crucial for maintaining efficient heat exchange and stable production.

[0004] Traditional plate cleaning methods mainly include manual cleaning and chemical cleaning. Although manual cleaning is intuitive and easy to operate, it is labor-intensive, difficult to clean, and the cleaning effect is limited by the experience and physical strength of the personnel. Especially in winter when the temperature is low, it is easy to cause frostbite to the hands of the cleaning personnel. Although chemical cleaning has a better cleaning effect, it requires the establishment of a complex cleaning circulation system, and the selection and use of cleaning agents need to be strictly controlled to avoid corrosion or damage to the plates.

[0005] Chinese Patent Application 1 (Application No.: 202223272701.X, Application Date: 2022.12.05) discloses a plate heat exchanger plate cleaning device. The device includes a frame, which is composed of legs and a top plate. Casters are installed at the bottom of the legs. A lifting roller mechanism and a movable roller mechanism are installed on the top plate of the frame. The lifting roller mechanism is used for preliminary cleaning of the plates. The movable roller mechanism can perform secondary cleaning of the corners or missed areas according to the cleaning situation. The steel wire roller has a low cleaning degree for half plates, which may require repeated washing, which can easily lead to resource waste, low cleaning degree, and low efficiency.

[0006] Therefore, it is essential to provide a plate cleaning device that is highly efficient, highly clean, and saves manpower. Utility Model Content

The fourth gear 84, the fifth gear 85, and the sixth gear 86 are all sleeved on the outside of the corresponding brush tube 7, and there is a gap between them and the brush tube 7.

[0064] It should be noted that the fourth gear 84, the fifth gear 85, the sixth gear 86, and the eighth gear 88 are all sleeved on the outside of the corresponding brush tube 7 or nozzle 6, and there is a gap between them. After the first motor 17 is turned on, it drives the second gear 82 and the first gear 81 to rotate after being acted upon by the reducer 18. The third gear 83, which meshes with the second gear 82, rotates with the second gear 82. The fourth gear 84, the fifth gear 85, the sixth gear 86, the seventh gear 87, and the eighth gear 88 also rotate at the speed of the first motor 17 after being acted upon by the reducer 18. However, since the fourth gear 84, the fifth gear 85, the sixth gear 86, and the eighth gear 88 are all sleeved on the outside of the corresponding brush tube 7 or nozzle 6, and there is a gap between them, the third brush tube 73, the fourth brush tube 74, the fifth brush tube 75, and the second nozzle 62 do not rotate with their corresponding top gears.

Along the front-rear direction y, the brush group is set at one end near the front support frame 200 and one end near the rear support frame 200. The brush group is provided with a nozzle group or the brush tubes 7 and nozzles 6 are alternately arranged.

[0068] It should be noted that within the fixed frame 201, along the direction from the plate inlet 202 to the plate outlet 203, the first nozzle 61, the first brush tube 71, the second brush tube 72, the third brush tube 73, the fourth brush tube 74, the fifth brush tube 75, the sixth brush tube 76, the second nozzle 62, the seventh brush tube 77, and the third brush tube 63 are arranged sequentially, as shown in the reference. Figures 1-5In use, the plate is placed into the cleaning device from one side of the plate inlet 202. The first motor 18 starts, and the second gear 82 rotates at a low speed after being reduced by the reducer 17. The first gear 81, the third gear 83 on the second brush tube 72, the fourth gear 84 on the third brush tube 73, the fifth gear 85 on the fourth brush tube 74, the sixth gear 86 on the bearing of the fifth brush tube 75, the seventh gear 87 on the bearing of the sixth brush tube 76, and the eighth gear 88 at the top of the second spray pipe 62 are all connected. The second gear 82 rotates at the same speed as the ninth gear 89 on the seventh brush tube 77. Since the second gear 82 is located between the first brush tube 71 and the second brush tube 72, the two brush tubes near the plate inlet 201 rotate in the same direction. When they rotate counterclockwise, they can assist the plate in entering the cleaning device. The end of the sixth gear 86 away from the fifth brush tube 75 is also provided with a sixth upper gear 862. The sixth upper gear 862 meshes with the motor gear 20. The number of teeth of the motor gear 20 is less than the number of teeth of the sixth upper gear 862. The motor gear 20 meshes with the ninth gear 89 on the seventh brush tube 77. The output shaft of the second motor 19 is connected; the bottom ends of the third brush tube 73, the fourth brush tube 74, and the fifth brush tube 75 are respectively equipped with a first lower gear 841, a second lower gear 851, and a third lower gear 861 that mesh with each other. After the second motor 19 starts, it meshes with the motor gear 20 and the sixth upper gear 862, achieving a certain speed reduction effect on the sixth upper gear 862. The sixth upper gear 862 drives the fifth brush tube 75 and the third lower gear 861 to rotate, and the first lower gear 841, the second lower gear 851, and the third lower gear 861 rotate. 1. The interlocking of the brush tubes allows the third brush tube 73, the fourth brush tube 74, and the fifth brush tube 75 to rotate faster than the other brush tubes, achieving a deeper cleaning effect. After the motor is turned on, the roller 9 runs, transporting the plate along the front-to-back direction y. After being sprayed by the spray tube group, the plate is brushed by the brush group, and then sprayed again by the spray tube group. After initial cleaning, it is brushed by multiple brush groups. Before the plate leaves the cleaning device, it passes through the spray tube group again, and both sides of the plate are sprayed to clean the brush marks, completing the cleaning process of the plate.

[0069] It should be noted that, in order to improve the cleaning effect, the bristle density and bristle length on the brush tube 7 in this utility model are different. Figure 1 Different shades of gray in the brush tube 7 represent brush tubes with different bristle density;

[0070] It also includes a base, which is a rectangular frame. The end of the base 100 away from the ground is fixedly connected to the support frame 200 to provide a certain support force for the entire cleaning device and improve the stability of the device. A support column 10 is set at the end of the base 100 near the ground. The support column 10 is located at the four corners of the base 100. The bottom end of the support column 10 is equipped with a wheel 12 to facilitate the movement of the cleaning device.

[0071] It should be noted that the wheel 12 of the plate cleaning device provided by this utility model can be a brake wheel with a braking function. Specifically, it can be one of the following: Henggu heavy-duty nylon universal brake, silent brake wheel, gravity-sensing automatic brake caster, and hydraulically assisted brake heavy-duty caster. This embodiment does not make a specific limitation. The Henggu heavy-duty nylon universal brake makes the brake pads tightly contact the wheel hub by manually pressing or rotating the brake pedal, and uses friction to achieve braking. The brake mechanism usually adopts a spring return design, and automatically resumes rotation after the brake is released. The silent brake wheel has a dual braking system, which achieves synchronous braking through mechanical linkage. The foot brake controls the wheel hub friction, and the side brake locks the steering shaft, providing double protection to prevent the equipment from sliding. The gravity-sensing automatic brake caster has a built-in gravity sensing mechanism. When the load exceeds the set value, it automatically triggers the mechanical locking device to limit the rotation of the wheel hub. It automatically unlocks after the load is removed and resumes the movement function. It can be set to automatically lock after the plate is placed to further improve the safety of the plate. The hydraulically assisted brake heavy-duty caster transmits braking force through a hydraulic system. The brake pedal pushes the hydraulic oil to push the piston, so that the brake pads press tightly against the wheel hub. Hydraulic brakes are characterized by high braking force and sensitive response.

[0072] Along the front-to-back direction y, at least two roller support frames 91 are spaced apart on the bottom crossbar 21. The roller support frames 91 are alternately arranged with the bearings 5. Along the up-down direction z, one end of the roller support frame 91 is fixedly connected to the bottom crossbar 21, and the other end is provided with a through hole. A roller 9 is fitted in the through hole. Along the left-to-right direction x, a roller 9 is arranged between two oppositely arranged roller support frames 91.

[0073] The water supply pipe 13 is connected to the water inlet, and a vertical water pump 14 is installed at the water inlet.

[0074] It should be noted that the vertical water pump 14 can be one of the following: ISG type vertical pipeline centrifugal pump, IHG type vertical stainless steel chemical pump, DL type vertical multistage centrifugal pump, CDLF type vertical stainless steel multistage pump, and NIS type vertical single-stage fire pump. The ISG type vertical pipeline centrifugal pump is a vertical design, occupying a small area and effectively saving space; it adopts an advanced hydraulic model, has high efficiency, low operating cost, effectively saves energy, operates smoothly, has low noise, low vibration, and a long service life; the IHG type vertical stainless steel chemical pump is made of stainless steel. With a long service life, optimized hydraulic design, high efficiency, and low operating costs, the DL-type vertical multistage centrifugal pump features high head, multistage design, high-quality bearings and seals, smooth operation, and low noise. The CDLF-type vertical stainless steel multistage pump adopts an all-stainless steel structure, is corrosion-resistant, has a long service life, and uses advanced hydraulic models and manufacturing processes, resulting in high efficiency and low operating costs. The NIS-type vertical single-stage fire pump meets fire protection standards and is suitable for booster water supply in fire protection systems. It uses a high-efficiency motor and hydraulic model, resulting in high efficiency and low energy consumption.

[0075] Example 3

[0076] This embodiment provides a detailed description of the materials used in each part of the plate cleaning device, based on Embodiment 2.

[0077] The bristles are made of keratin.

[0078] It should be noted that if the bristles are made of horn, specifically natural animal hair such as pig bristles or horsehair, then the brush bristles are suitable. Pig bristles are highly durable and water-resistant, making them ideal for use in humid environments. They are also anti-static and heat-resistant, making them suitable for applications requiring high-temperature cleaning. The oil-absorbing properties of pig bristles allow them to effectively remove dirt and grease during cleaning. Horsehair is tough and wear-resistant, but not resistant to acids and alkalis. Its softness and elasticity prevent damage to the surface being cleaned. Horsehair is also anti-static and highly absorbent, making it suitable for applications requiring both. Horsehair bristles effectively absorb dirt and moisture, gently removing dust and grease from the skin. Both pig bristles and horsehair are natural, biodegradable, and environmentally friendly. The durability of natural animal hair extends their lifespan, reducing the frequency of bristle replacement. Horn-based bristles generally provide better cleaning than synthetic fiber bristles, effectively removing dirt and grease.

[0079] Both gear 8 and bearing 5 are made of nylon.

[0080] It should be noted that nylon material itself has lubricating properties, which can reduce friction without additional lubricating oil. This is especially suitable for cleaning equipment that frequently comes into contact with water or cleaning agents, preventing lubricating oil from contaminating the cleaning fluid. Nylon has strong resistance to water, acid and alkali solutions, and common cleaning agents (such as detergents and disinfectants). It can be immersed in or in contact with cleaning media for a long time without corrosion or degradation, extending the service life of the equipment. Nylon has a low modulus of elasticity, which can absorb vibration and impact during operation, reduce equipment noise, and improve operating comfort. Nylon has a lower density than metal, which can reduce the overall weight of the equipment and reduce energy consumption. After modification treatment, the wear resistance of nylon is significantly improved, which can withstand high-speed and high-load operation and reduce the decrease in precision caused by wear.

[0081] As can be seen from the above embodiments, the plate cleaning device provided by this utility model achieves at least the following beneficial effects:

[0082] It is understood that this utility model provides a plate cleaning device, including a fixed frame, a brush assembly, and a spray pipe assembly; two fixed frames are arranged opposite each other in the left-right direction, and rollers are arranged between the fixed frames. The fixed frame includes a front vertical rod, an upper horizontal rod, a rear vertical rod, and a bottom horizontal rod connected in sequence. The fixed frame is set inside a support frame.
