Description

Technical Field

[0001] This utility model belongs to the field of security inspection machine cleaning technology, specifically relating to a security inspection machine cleaning device. Background Technology

[0002] With the widespread use of security screening equipment in public places such as airports and train stations, the cleanliness of the security scanners directly affects the accuracy and efficiency of the equipment. The accumulation of dirt and dust may interfere with the X-ray imaging system, leading to false alarms or missed alarms, thus affecting the accuracy and efficiency of security checks.

[0003] Currently, the cleaning method used on-site for the extended conveyor belt of security scanners requires the scanner to be stopped during cleaning, with manual wiping by operators. This results in discontinuous operation and incomplete cleaning. Regular cleaning can reduce equipment wear and tear, extend its lifespan, and lower maintenance costs. The cleaning and maintenance of security scanners are crucial for their normal operation and detection accuracy. Furthermore, during peak passenger flow periods, it's impossible to clean immediately after cleaning, leading to contamination of passenger luggage. A clean and tidy security screening environment improves the passenger experience, reduces discomfort caused by dirt on equipment surfaces, and also reduces the risk of cross-infection from equipment contamination.

[0004] Chinese patent CN109368189A discloses a cleaning and disinfection device for the conveyor belt of a security X-ray machine. This patent employs a design where a cleaning mechanism is fixedly mounted above a water tank, contacting the X-ray machine's conveyor belt. A scraping mechanism is rotatably mounted on one side of the water tank, and a collection mechanism is positioned below the scraping mechanism. The device is fixedly positioned below the conveyor belt, which moves from the scraping mechanism to the cleaning mechanism. First, the scraping mechanism removes the adhering debris, and then the cleaning mechanism cleans the belt, ultimately achieving the purpose of cleaning and disinfecting the security X-ray machine's conveyor belt. This solution has a clever structure and requires no modification to the existing security X-ray machine; simply placing the device below the conveyor belt is sufficient. While this device eliminates the need for manual wiping and allows for immediate cleaning as needed, the brushes inevitably shed particles during the cleaning process, leading to less than ideal cleaning results. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a security inspection machine cleaning device to solve the technical problem that the existing security inspection machine cleaning devices inevitably produce shed particles during the cleaning process, resulting in poor cleaning effect.

[0006] This utility model provides a cleaning device for a security scanner, including a front-end device. The front-end device is equipped with a water circulation component. A base is provided at the bottom of the front-end device. A brush cylinder is connected to the base. A brush is provided in the brush cylinder. A plurality of spray heads are arranged on the surface of the brush. A water tank is connected to one side of the brush cylinder. A filter component is provided in the water tank.

[0007] Preferably, the water circulation assembly includes a water tank with an inlet, a outlet, and a spray nozzle. A filter screen is installed at the bottom of the spray nozzle. A return water pump is connected to one side of the water tank, and a pump and an inlet are connected to the other side. A spray pump is connected to one side of the brush cylinder.

[0008] Preferably, the filtration assembly includes a filter tank, the top of the water tank has a filter tank, and a filter cloth is provided inside the filter tank.

[0009] Preferably, a number of push rods are connected to one side of the brush cylinder.

[0010] More preferably, a set of push rods is connected to one side of the brush cylinder.

[0011] Preferably, a drying device is connected to one side of the front-end device. The drying device includes an industrial air curtain super blade. A rear fan is connected to the side of the industrial air curtain super blade away from the front-end device. Connecting screws are installed on both sides of the industrial air curtain super blade.

[0012] Preferably, the air outlet of the industrial air curtain super blade is a straight blade, and the width of the air outlet is 0.5mm-2.5mm.

[0013] Preferably, the rear fan is a high-pressure vortex fan, a vortex air pump, or a high-speed energy-saving fan.

[0014] Preferably, the bottom of the bracket is symmetrically provided with several sets of pulleys.

[0015] More preferably, the bracket has two sets of pulleys symmetrically arranged at its bottom.

[0016] Preferably, the base is symmetrically provided with several sets of support legs around its perimeter.

[0017] More preferably, the base is provided with two sets of support legs symmetrically arranged around its perimeter.

[0018] Preferably, a drive motor is connected to one side of the brush cylinder.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention provides a cleaning device for security scanners. By installing a water circulation component on the front-end equipment, the water in the tank remains clean while the brushes in the brush cylinder clean the conveyor belt, achieving the purpose of recycling. Water mist is sprayed through the spray nozzles on the surface of the brush cylinder to keep the brushes moist during the cleaning process, preventing dry friction that could cause the brush fibers to fall off. At the same time, the water flow washes away the particles that fall off the brushes themselves. By installing a filter component in the water tank, particles that fall off during the cleaning process can be intercepted, thereby achieving wastewater filtration and recycling. This not only purifies the wastewater but also significantly improves the water resource utilization rate.

[0021] Furthermore, a return water pump draws the sediment from the brush barrel into the filter paper at the top of the water tank for filtration. The filtered water then returns to the water tank. A water pump discharges wastewater, a water injection pump replenishes clean water, and a spray pump draws the filtered clean water for spraying, forming a closed-loop cycle and reducing water waste. The filter screen at the bottom of the spray intake initially intercepts large particulate pollutants, preventing them from entering the spray system and clogging the nozzles, while also reducing particulate residue on the brush surface.

[0022] Furthermore, the filter tank collects the returned water, and the filter cloth further intercepts fine particles (such as brush fibers, dust, etc.). The dual filtration ensures that the circulating water is clean and prevents particles from re-attaching to the conveyor belt through the water flow.

[0023] Furthermore, by adjusting the height of the brush cylinder with a push rod, the contact pressure between the brush and the conveyor belt can be optimized to avoid excessive wear and tear on the brush and the shedding of particles due to excessive pressure, while also adapting to different conveyor belt thicknesses.

[0024] Furthermore, the air-drying equipment blows away residual moisture from the conveyor belt surface after cleaning. The high-speed airflow simultaneously removes fine particles not intercepted by the water circulation system, further reducing surface contaminant residue. Compared to traditional natural air drying or mechanical wiping, this significantly improves drying speed and eliminates the need for downtime. Connecting screws support the industrial air curtain super blades, allowing for adjustments to their length and angle to adapt to conveyor belts of varying widths and ensure uniform drying coverage. The combination of the industrial air curtain super blades and a rear-mounted fan ensures ample air intake and uniform air output. The rear-mounted fan drives the super blades, with parameters matched to the air consumption per meter of the super blades.

[0025] Furthermore, the straight blades with a width of 0.5mm-2.5mm enhance the airflow speed, improve the purging efficiency of residual particles, and accelerate the evaporation of moisture on the conveyor belt surface.

[0026] Furthermore, employing high-pressure vortex fans, vortex air pumps, or high-speed energy-saving fans can significantly enhance the impact force of the air knife. Compared to traditional axial flow fans, energy consumption is reduced and noise is decreased.

[0027] Furthermore, the pulley support device can quickly move to areas of severe contamination on the conveyor belt, avoiding blind spots in cleaning caused by fixed installation and reducing the accumulation of particulate matter on the conveyor belt.

[0028] Furthermore, the support legs ensure stable fixation of the cleaning device during operation, avoiding the problem of complex installation of the cleaning device.

[0029] Furthermore, the brush cylinder is driven by a motor to rotate, adapting to the cleaning needs of conveyor belts with different levels of contamination. Attached Figure Description

[0058] See Figures 1 to 9

[0059] The main purpose of the security inspection cleaning device of this utility model is to clean the security inspection conveyor belt 1. On the one hand, it cleans the water on the surface of the conveyor belt 1 to achieve the purpose of uniform cleaning without scratches. On the other hand, it can quickly dry the water on the surface of the conveyor belt 1, so as to achieve the final effect of making the surface of the conveyor belt 1 clean.

[0060] How to use the cleaning device of this utility model:

[0061] 1) When the switch of the electrical box is turned on, the push rod 11, the drive motor 9 and the spray pump 10 are opened. The push rod 11 pushes the brush cylinder 8 to rise. At the same time, the drive motor 9 starts to work, causing the brush cylinder 8 to roll. After the brush cylinder 8 is lifted by the push rod 11, it comes into contact with the conveyor belt 1. At the same time, the spray pump 10 draws water from the water tank 15 to the spray head 16. The spray head 16 sprays water mist onto the surface of the brush cylinder 8, cleaning and wetting the brushes on the brush cylinder 8. Thus, the brush cylinder 8 cleans the conveyor belt 1 with water. During this process, a timer can be used to set a certain time for the conveyor belt 1 to rotate 3 times.

[0062] 2) After the cleaning of conveyor belt 1 is completed, the pre-equipment 2 stops working, the push rod 11 descends, the brush cylinder 8 no longer contacts the conveyor belt 1, and the cleaning operation of the pre-equipment 2 ends.

[0063] 3) After the pre-installed equipment 2 has finished working, start the rear fan 3. During the rotation of the conveyor belt 1, the air blown out of the air outlet of the industrial air curtain super blade 4 will dry the water on the conveyor belt 1. During this process, a certain time can be set using the timer in the electrical box. When the time is up, the rear fan 3 will stop working and the conveyor belt 1 will be dried.

[0064] The initial state of the pusher 11 is as follows: Figure 6 As shown, the brush cylinder 8 is in slight contact with the conveyor belt 1, and the state of the push rod 11 when it is raised to 15mm is as follows. Figure 7 As shown, push rod 11 contacts conveyor belt 1. After cleaning, push rod 11 descends 15mm as shown. Figure 8 As shown, the brush cylinder 8 detaches from the conveyor belt 1 and returns to its initial state.

[0065] This utility model's security scanner cleaning device enables one-button cleaning without additional manual operation. By connecting an external electrical box to the device and installing a timer in the box, the device can time the front-end device 2 or the drying device. For example, after 2 minutes, the front-end device 2 will automatically stop, the push rod 11 will automatically descend, the brush cylinder 8 will no longer contact the conveyor belt 1, the cleaning of the conveyor belt 1 will be completed, and the drying device will automatically start. After 10 minutes, the drying device will be powered off, and the entire cleaning and drying process will end. The cleaning time can be set according to the degree of dirt on the security scanner and actual needs. The device also features automatic water intake and drainage, making it convenient to operate.

[0066] This utility model's cleaning device also provides a preferred embodiment, namely, the cyclical control process of the cleaning device can be completed by setting peripheral components on the cleaning device. The peripheral components include control electrical components and a water tank assembly. The control electrical components include a matching electrical box and electrical units, and the water tank assembly includes a water tank. A water pump automatically drains dirty water from the water tank with one button, and a water pump automatically fills the tank with water with one button. The system automatically stops when the water tank is full. The control electrical components are designed with reference to process control flow. The water tank unit is used for the periodic replacement of water in the upstream equipment's water tank, ensuring regular and quantitative water changes and establishing a standardized operation.
