Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial refrigeration technology, specifically a dustproof air cooler for industrial refrigeration. Background Technology
[0002] Industrial evaporative air coolers are environmentally friendly products that require no compressors, no refrigerants, and produce no pollution. They utilize the evaporative cooling principle of fresh outdoor air to lower the temperature and create convection airflow between the air and the indoor environment, thus achieving indoor ventilation and cooling. Compared to traditional compressor air conditioning systems, the cost is less than half, and the equipment does not occupy any building space. The system is simple, easy to install and maintain quickly, and requires no professional maintenance personnel. It embodies energy saving, user-friendliness, aesthetics, and environmental protection, providing a perfect solution for ventilation and cooling in environments such as electronics, textiles, shoemaking, plastics, machinery workshops, cigarette factories, modern homes, offices, supermarkets, hospitals, entertainment venues, and waiting rooms.
[0003] In industrial settings, many industrial products, before reaching their final form, generate odors, harmful dust, or ultrafine particles. Therefore, existing industrial air coolers often incorporate filtration systems to remove most dust from the airflow at both the intake and exhaust ends, preventing harmful dust from being blown into the air and spreading over a wider area, thus impacting the health of personnel and ultimately failing to improve the working environment. However, existing air coolers with dust removal features a single air inlet plate on the outer wall, serving functions such as fixing the filter module, aesthetics, protection, and safety. The most common method for setting the air inlet plate is a heat dissipation structure with stamped fins on the sheet metal outer wall. During operation, due to airflow friction, insufficient grounding of the casing, and magnetic fields from wires and electrical wires, static electricity can cause dust accumulation on the casing, further weakening the filtration effect. Directly removing this dust can lead to it being sucked into the filter module, increasing the filtration pressure and shortening the filter's lifespan. In view of these problems, a dustproof air cooler for industrial refrigeration is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a dustproof air cooler for industrial refrigeration to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof air cooler for industrial refrigeration, comprising an air cooler body, the air cooler body comprising a main unit, the side wall of the main unit being provided with an air outlet and several air inlets, the outer wall of the air inlets being fitted with a flow guide frame, and the interior of the flow guide frame being fitted with an air duct cleaner.
[0006] An integral ventilation opening is punched into the outer wall of the air inlet plate;
[0007] The flow guide frame includes a dust exhaust pipe, the bottom end of which is connected to a welded outer shell, and the outer wall of the outer shell has an air inlet.
[0008] The air duct cleaner includes a slide bar, the number of which is the same as the number of longitudinally arranged ventilation openings. A dust removal component is provided on the outside of the slide bar. Both ends of the dust removal component can be closed inside the ventilation opening and the air inlet. A hollow structure is provided in the middle of the dust removal component.
[0009] Several sliding rods are welded together by two connecting rods, and the group of sliding rods moves horizontally inside the outer shell.
[0010] The dust removal component is inclined, and the inclination angle of the dust removal component is the same as the angle of the stamped and bent fins of the ventilation opening.
[0011] Preferably, a fixing frame is welded to the outer wall of the outer shell, and an expansion joint is provided inside the fixing frame. The displacement end of the expansion joint is positioned and connected to a sliding rod.
[0012] Preferably, a fixed rod with the same structural dimensions as the slide rod is welded separately to the displacement end of the telescopic device, and the top and bottom ends of the fixed rod are welded and fixed to the connecting rod respectively.
[0013] Preferably, the air inlet plate is equipped with filter cotton.
[0014] Preferably, an extension tube is installed at the top end of the dust exhaust pipe, and an external vacuum cleaner is fitted on the outside of the extension tube.
[0015] Preferably, the inner wall of the dust exhaust pipe is provided with a contact switch that extends through to the outer wall of the dust exhaust pipe. When the vacuum cleaner's suction port is connected to the outer wall of the dust exhaust pipe, the inner wall of the suction port will press against the contact switch.
[0016] Preferably, the dust removal component includes a first scraper and a second scraper, and a connecting strip is welded between the first scraper and the second scraper.
[0017] Preferably, the structural dimensions of the first scraper are the same as those of the air inlet, and the structural dimensions of the second scraper are the same as those of the vent.
[0018] Preferably, a slider is welded to the inner wall of the scraper, and the slider is slidably mounted on the outer surface of the slide rod.
[0019] Preferably, the number and location of the air inlets on the outside of the housing are the same as the number and location of the ventilation openings, and the number of dust removal components used is the same as the number of air inlets.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an air duct cleaner with an external controllable switch for the air inlet and the ability to scrape dust during the switching process. In use, the sliding connector moves inward or outward relative to the air cooler body via a telescopic joint, causing the sliding rod to move horizontally, which in turn causes the dust removal component to move horizontally. While the dust removal component is moving horizontally, it rubs against the outer wall of the air vent. Influenced by the shape of the outer wall of the air vent, the dust removal component is passively raised and lowered, sliding on the inner wall of the air vent to achieve the purpose of scraping dust. This effectively solves the problem that the existing industrial refrigeration air cooler's external air intake grille is affected by airflow friction, insufficient shell grounding, wires, and magnetic fields, which cause static electricity on the outer shell, resulting in dust accumulation that negatively impacts the air exchange quality and working environment.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0033] Please see Figure 1-10 This utility model provides a technical solution: a dustproof air cooler for industrial refrigeration, including an air cooler body 1, the air cooler body 1 including a main unit 11, the side wall of the main unit 11 is provided with an air outlet 14 and several air inlet plates 12, the outer wall of the air inlet plate 12 is equipped with a flow guide frame 2, and the interior of the flow guide frame 2 is equipped with an air duct cleaner 3.
[0034] An integral ventilation opening is stamped on the outer wall of the air inlet panel 12;
[0035] The flow guide frame 2 includes a dust exhaust pipe 21, the bottom end of which is connected to a shell welded together, and the outer wall of the shell has an air inlet.
[0036] The air duct cleaner 3 includes a slide bar 32. The number of slide bars 32 is the same as the number of longitudinally arranged ventilation openings. A dust removal component 33 is provided on the outside of the slide bar 32. Both ends of the dust removal component 33 can be closed inside the ventilation opening and the air inlet. A hollow structure is provided in the middle of the dust removal component 33.
[0037] Several sliding rods 32 are welded together by two connecting rods 34, and the group of sliding rods 32 moves horizontally inside the outer shell.
[0038] The dust collector 33 is inclined, and the inclination angle of the dust collector 33 is the same as the angle of the stamped and bent fins of the vent.
[0039] This utility model provides an air duct cleaner 3 with an external controllable switch for the air inlet and the ability to scrape dust during the switching process. In use, the sliding connector 31, connected by the telescopic connector 23, moves inward or outward relative to the air cooler body 1, causing the sliding rod 32 to move horizontally, thereby causing the dust removal component 33 to move horizontally. While the dust removal component 33 moves horizontally, it rubs against the outer wall of the air vent. Influenced by the shape of the outer wall of the air vent, the dust removal component 33 passively rises and falls, sliding on the inner wall of the air vent to achieve the purpose of scraping dust. This effectively solves the problem that the existing industrial refrigeration air cooler's external air intake grille is affected by airflow friction, insufficient shell grounding, wires, and magnetic fields, which cause static electricity on the outer shell, resulting in dust accumulation that negatively impacts the quality of air exchange and the working environment.
[0040] Specifically, a fixed frame 22 is welded to the outer wall of the casing, and an expansion joint 23 is installed inside the fixed frame 22. The displacement end of the expansion joint 23 is positioned and connected to a sliding rod 32. The bottom of the casing is closed, and an opening for cleaning is opened on the side wall of the casing. The top of the dust exhaust pipe 21 is connected to the input end of an external suction dust collector. When cleaning is required, the expansion joint 23 first moves to indirectly drive the dust collector 33 to scrape off the dust. After the dust is scraped off, the dust collector 33 can close the vent and the air inlet, so the dust will accumulate inside the casing. Then the external dust collector is started, and air is drawn from inside the dust exhaust pipe 21. The air enters the inside of the casing from the bottom opening, and the dust that has just been removed is recycled and carried out, ultimately forming a closed dust collection effect.
[0041] The dust removal equipment mentioned above can be a simple vacuum cleaner equipped with an ultra-fine filter, or it can be a large external bag filter, centrifugal dust collector, etc. Multiple devices can be connected to one dust collector to achieve the dust removal effect. However, the best choice is still a small vacuum cleaner. The suction port of the vacuum cleaner can be replaced with a suction port that is the same shape as the dust discharge pipe 21 and has a rubber elastic layer inside. During use, the suction power of the device further improves the fixed stability between the suction port and the dust discharge pipe 21, ensuring that the suction port will not fall off. In addition, the small vacuum cleaner is also portable and can be moved around to handle the equipment that needs dust removal.
[0042] Since the air cooler body 1 is generally equipped with at least 2 air inlet surfaces, and in extreme cases, 5 air inlet surfaces can be set, and each air inlet surface is equipped with a guide frame 2 and an air duct cleaner 3, when in use, closing only the air duct cleaner 3 at one end will not affect the operation of the other air inlet surfaces. This ensures that the air cooler can also perform dust removal while it is running, but it is not possible to close all air inlet surfaces for dust removal while the air cooler is running.
[0043] Specifically, a fixed rod with the same structural dimensions as the slide rod 32 is welded separately to the displacement end of the telescopic device 23. The top and bottom ends of the fixed rod are welded and fixed to the connecting rod 34, respectively. The telescopic device 23 is preferably an electric push rod structure. A contact switch penetrating to the outer wall of the dust exhaust pipe 21 is provided on the inner wall of the dust exhaust pipe 21. When the suction port of the vacuum cleaner is connected to the outer wall of the dust exhaust pipe 21, the inner wall of the suction port will squeeze the contact switch. The contact switch is electrically connected to the switch of the electric push rod and the external control circuit. When the contact switch is normally closed, the circuit is connected. When the electric actuator is powered on, it typically features a travel limit function to prevent the actuator from exceeding its maximum travel limit even when the motor is not powered on or under other conditions. This function eliminates the need for a separate travel length control circuit. Therefore, when the contact switch is normally closed, the electric actuator will automatically move to its maximum position, closing the dust removal component 33 and the corresponding vent. After dust removal is complete, when the suction port is disconnected, the contact switch is normally open, and the circuit sends a retraction signal to the electric actuator to automatically return it to its original position, continuing to provide normal ventilation.
[0044] Specifically, the air inlet plate 12 is equipped with filter cotton 13. The bottom of the air inlet plate 12 is hinged to the main unit 11. The air inlet plate 12 can be tilted outward to open, making it easy to replace the filter cotton 13.
[0045] Specifically, an extension pipe is installed at the top of the dust exhaust pipe 21, and an external vacuum cleaner is fitted on the outside of the extension pipe.
[0046] Specifically, the telescopic device 23 is an electric actuator structure.
[0047] Specifically, the dust removal component 33 includes a first scraper 331 and a second scraper 333, with a connecting strip 332 welded between the first scraper 331 and the second scraper 333.
[0048] Specifically, the structural dimensions of scraper 331 are the same as those of the air inlet, and the structural dimensions of scraper 333 are the same as those of the vent. A sealing structure can be provided between scraper 331 and scraper 333 and the air inlet and vent. This sealing structure can directly close the air inlet and vent when it reaches the closed position.
[0049] The thickness of scraper 1 331 and scraper 2 333 is at least three times the thickness of air inlet plate 12 and outer shell. With the thickened scraper 1 331 and scraper 2 333, when the dust removal component 33 is running, scraper 1 331 and scraper 2 333 will not fall off to the outside of the air inlet plate 12 or outer shell that needs to be sealed, causing the dust removal component 33 to fall off. The air inlet opened on the outside of the outer shell is preferably the same size and angle as the ventilation opening.
[0050] Specifically, a slider is welded to the inner wall of scraper 331, and the slider is slidably mounted on the outer surface of slide rod 32.
[0051] Specifically, the number and location of the air inlets on the outside of the casing are the same as the number and location of the ventilation openings, and the number of dust removal components 33 used is the same as the number of air inlets.
[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
[0053] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
