Description

Technical Field

[0001] This invention relates to the field of air conditioning, and in particular to an energy-saving control system for industrial plant workshops. Background Technology

[0002] To ensure proper air circulation and a suitable temperature within industrial plants, thereby providing a comfortable working environment for employees, air conditioning systems are needed to supply filtered and cooled or heated air. During this process, timely unclogging of the filters can significantly reduce fan resistance, lower fan power consumption, and prevent decreased heat exchange efficiency due to dust accumulation and blockage. This ensures efficient operation of heat recovery devices and surface coolers, reducing the load on energy-intensive equipment such as compressors.

[0003] The prior art CN202510638184.2 discloses a ventilation and air exchange device for steel structure workshops. By adjusting the motor to drive the adjusting shaft to rotate, the mounting plate is driven to rotate. The movable rod drives the guide plate to slide along two guide columns, and then drives the vertical plate to move horizontally. At the same time, the unblocking rod moves horizontally and inserts into the filter hole to unblock the filter hole, avoid the filter hole from being blocked, and improve the filtration effect.

[0004] The prior art CN202410977214.8 discloses an air conditioning device for workshops with a secondary return air structure. The device controls the amount of recirculated gas and fresh air entering the workshop through the return air pipe and the air inlet pipe, respectively, thereby improving resource utilization. In addition, the device controls the entry point of the return air by using the first return air inlet and the second return air inlet, effectively utilizing the humidity in the workshop air and the humidity in the fresh air to achieve uniform mixing, thereby improving the energy-saving effect of the device.

[0005] In the aforementioned existing technologies, the blockages cleaned from the filter surface are not specifically addressed, leaving the possibility of secondary clogging. As air exchange time increases, a large amount of blockages accumulate on the filter surface, gradually reducing the effective ventilation area of ​​the filter and increasing the fan's operating resistance, which is detrimental to achieving energy-saving goals. Summary of the Invention

[0006] The core of this invention lies in dynamically adjusting the cross-sectional shape of the filter belt by switching components, allowing the clogged area to be immersed in the cleaning solution for efficient unblocking, thereby ensuring a constant effective ventilation area. This solves the problems of secondary pollution from surface blockages in existing technologies and the reduction of effective ventilation area with increasing filtration time. Simultaneously, a barrier plate shields the immersed area of ​​the filter belt, preventing wastewater from contaminating the inner surface of the filter belt after immersion cleaning, thus ensuring cleaning quality.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An energy-saving control system for an industrial plant workshop includes a refrigeration cabinet and a heating cabinet installed on one side of the plant. A filter cabinet is arranged on the side of the refrigeration cabinet and the heating cabinet away from the plant. A filter belt is installed inside the filter cabinet. A ventilation opening is opened on the surface of the filter cabinet away from the refrigeration cabinet. An upper rotating rod is rotatably installed on the inner wall of the filter cabinet near the top. A switching assembly for changing the cross-sectional shape of the filter belt is arranged inside the filter cabinet. The switching assembly includes a first slider and a second slider that are slidably installed inside the filter cabinet. A lower rotating rod is rotatably installed on the surface of both the first slider and the second slider. The upper rotating rod and the two lower rotating rods are connected by the filter belt. The switching assembly also includes a sliding rod and a fixing plate that are fixedly installed on the inner wall of the filter cabinet. A traction rope is wound around the surface of the sliding rod. A connecting rod is installed on the top of the first slider. The two ends of the traction rope are connected to the surface of the connecting rod and the second slider, respectively. A first electric push rod with a power end connected to the surface of the connecting rod is installed on the bottom of the fixing plate. A counterweight is connected to the bottom of the second slider.

[0009] Furthermore, the filter cabinet is equipped with L-shaped support plates inside. A waterproof and breathable plate and a fan are installed on the top of the support plates. The waterproof and breathable plate is made of waterproof and breathable material, and the height of the support plates is higher than the height of the ventilation opening.

[0010] Furthermore, the inner wall of the filter cabinet is provided with a vertically arranged No. 1 slide groove and an inclined No. 2 slide groove. The No. 1 slider and the No. 2 slider are slidably connected inside the No. 1 slide groove and the No. 2 slide groove, respectively. The surface of the slide rod is fitted with a limit plate, and the traction rope is located in the middle of the limit plate.

[0011] Furthermore, two counterweights are located on both sides of the filter belt, and a second electric actuator is embedded inside the counterweight. The power end of the second electric actuator is connected to a storage box, and a suction pump is installed on the top of the storage box. The output and input ends of the suction pump are connected to adapter pipes, respectively.

[0012] Furthermore, the upper rotating rod and the lower rotating rod connected to the surface of the first slider are located on the same vertical axis. A limiting rod is fixedly installed on the inner wall of the filter cabinet, located between the vent and the first electric push rod, and the limiting rod is located below the vent.

[0013] Furthermore, the plant, refrigeration cabinet, heating cabinet, and filter cabinet are all connected by air supply pipes, and control valves are installed on the surface of the air supply pipes. The filter cabinet contains cleaning fluid with the liquid level below the vent. A drive motor with its output end connected to one end of the upper rotating rod is installed on the surface of the filter cabinet.

[0014] Preferably, the surfaces of the two sliders that are close to each other are fixed with baffle plates. The lower rotating rod and the connecting rod on the surface of the slider penetrate through the interior of the baffle plate. The side of the baffle plate away from the slider is in contact with the edge of the filter belt.

[0015] Furthermore, the barrier plate has a constraint groove inside, and a telescopic sleeve plate is installed inside the constraint groove. A spring for resetting is installed inside the telescopic sleeve plate.

[0016] Furthermore, the inner wall of the constraint groove is provided with an inner recess, and both sides of the telescopic sleeve plate are slidably fitted into the inside of the inner recess.

[0017] Compared with the prior art, the advantages of this invention are:

[0018] (1) This solution dynamically adjusts the cross-sectional shape of the filter belt by switching components, so that the blocked area can be immersed in the cleaning solution for efficient unblocking, maintaining a constant effective ventilation area. The first electric actuator drives the first slider to rise and fall, and cooperates with the counterweight and the second slider to ensure that the filter belt always maintains stable tension. The immersion depth can be adjusted according to the thickness of the sediment layer to avoid cleaning in the flocculated sediment layer. At the same time, the suction pump regularly removes the sediment to maintain the cleanliness of the cleaning solution. This effectively reduces the frequency of filter belt blockage, and can also clean and dry the filter belt, so that the operating resistance of the fan components remains stable for a long time, thereby achieving energy saving effect.

[0019] (2) This solution adds a barrier plate to form an effective enclosure on both sides of the filter belt immersion area, preventing sewage containing blockages from spreading to the inside of the filter belt during the cleaning process, thus ensuring the cleaning quality. As the first slider rises, the limit rod coincides with the notch, which has a pressing effect on the telescopic sleeve plate. However, because part of the telescopic sleeve plate is located in the recessed groove, the sealing and waterproofing effect of the constraint groove can still be maintained. Furthermore, the second slider moves diagonally downwards, and together with the second electric push rod, it lifts the storage box, so that the upward movement of the barrier plate is not disturbed. While maintaining the enclosure function, it does not affect the normal movement of the switching components, further improving the cleaning efficiency. Attached Figure Description

[0035] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0036] Example 1:

[0037] Please see Figures 1-6An energy-saving control system for an industrial plant workshop includes a refrigeration cabinet 100 and a heating cabinet 200 installed on one side of the plant. A filter cabinet 300 is arranged on the side of the refrigeration cabinet 100 and the heating cabinet 200 away from the plant. A filter belt 5 is installed inside the filter cabinet 300. A ventilation opening is provided on the surface of the filter cabinet 300 away from the refrigeration cabinet 100. An upper rotating rod 9 is rotatably installed on the inner wall of the filter cabinet 300 near the top. A switching assembly for changing the cross-sectional shape of the filter belt 5 is arranged inside the filter cabinet 300. The switching assembly includes a first slider 602 and a second slider 605 slidably installed inside the filter cabinet 300. Both slider 1 (602) and slider 2 (605) have a lower rotating rod 8 rotatably mounted on their surfaces. The upper rotating rod 9 and the two lower rotating rods 8 are connected by a filter belt 5. The switching assembly also includes a slide rod 601 and a fixing plate fixedly mounted on the inner wall of the filter cabinet 300. A traction rope 603 is wound around the surface of the slide rod 601. A support rod 604 is installed on the top of slider 1 (602), and the two ends of the traction rope 603 are respectively connected to the support rod 604 and the surface of slider 2 (605). A first electric push rod 608 with its power end connected to the surface of the support rod 604 is installed at the bottom of the fixing plate. A counterweight 606 is connected to the bottom of slider 2 (605).

[0038] Please see Figure 2 , Figure 4 and Figure 5 The filter cabinet 300 has an L-shaped support plate 302 installed inside. A waterproof and breathable plate 301 and a fan 303 are installed on the top of the support plate 302. The waterproof and breathable plate 301 is made of waterproof and breathable material. The height of the support plate 302 is higher than the height of the ventilation opening.

[0039] Please see Figure 5 The inner wall of the filter cabinet 300 is provided with a vertically arranged first slide groove 304 and an inclined second slide groove 305. The first slider 602 and the second slider 605 are slidably connected to the inside of the first slide groove 304 and the second slide groove 305, respectively. The surface of the slide rod 601 is fitted with a limit plate, and the traction rope 603 is located in the middle of the limit plate.

[0040] Please see Figures 2-6 Two counterweights 606 are located on both sides of the filter belt 5, and a second electric actuator 10 is embedded inside the counterweight 606. The power end of the second electric actuator 10 is connected to the storage box 607, and a suction pump 11 is installed on the top of the storage box 607. The output end and the input end of the suction pump 11 are respectively connected to the adapter pipe 12.

[0041] Please see Figure 2 and Figure 4The upper rotating rod 9 and the lower rotating rod 8 connected to the surface of the first slider 602 are located on the same vertical axis. The inner wall of the filter cabinet 300 is fixedly installed with a limiting rod 7 located between the vent and the first electric push rod 608, and the limiting rod 7 is located below the vent.

[0042] Please see Figure 1 and Figure 8 The factory, refrigeration cabinet 100, heating cabinet 200 and filter cabinet 300 are all connected by air supply pipes, and control valves are installed on the surface of the air supply pipes. The filter cabinet 300 contains cleaning fluid with the liquid level below the vent. The filter cabinet 300 is equipped with a drive motor 4 whose output end is connected to one end of the upper rotating rod 9.

[0043] Specifically, when using this system to provide air conditioning services for the factory (the system has energy-saving characteristics because it can effectively circulate through the filter belt 5), the fan component 303 inside the filter cabinet 300 draws in air from outside the cabinet. After being intercepted and filtered by the filter belt 5, the air enters the cavity where the fan component 303 is located through the waterproof and breathable plate 301. Then, as needed, it selectively enters the interior of the refrigeration cabinet 100 or the heating cabinet 200. After undergoing the corresponding refrigeration or heating treatment, it enters the factory through the air supply pipes and is then delivered to different areas of the factory through the air supply branch pipes installed in the factory.

[0044] During the above process, due to the presence of the cleaning fluid, the air after suction and filtration contains a certain amount of moisture, which may cause corrosion to the air supply pipes. To improve this situation, a waterproof and breathable sheet 301 is used to dehumidify the air.

[0045] The space formed by the inner wall of the filter cabinet 300 with the ventilation opening and the support plate 302 is a cleaning chamber. The cleaning fluid stored in the cleaning chamber contains a flocculant, which is used to flocculate the dust in the cleaning fluid and make it settle at the bottom of the filter cabinet 300.

[0046] The cross-sectional width of the filter belt 5 is smaller than the inner cross-sectional width of the filter cabinet 300, but larger than the cross-sectional width of the vent. During filtration using the filter belt 5, the drive motor 4 can switch between different working surfaces, ensuring that the vent is always in an effective ventilation state. As the working surfaces of the filter belt 5 switch, the blocked area moves to below the vent and is immersed in the cleaning solution. To further improve the unblocking effect, an ultrasonic transducer or other vibration source can be installed on the surface of the first slider 602 to promote the dislodgement of blockages and full immersion in the cleaning solution. After cleaning, the previously blocked working surface of the filter belt 5 is cleared and ready for subsequent use.

[0047] Please see Figure 7 and Figure 8The fallen blockage is flocculated and precipitated. As the flocculated sediment accumulates, the first slider 602, which is initially close to the bottom of the filter cabinet 300, needs to be lifted. The first electric push rod 608 drives the connecting rod 604 to lift, which in turn drives the lower rotating rod 8 on the surface of the first slider 602 and the filter belt 5 on the surface of the lower rotating rod 8 to lift. This ensures that the filter belt 5 is in the upper clear liquid layer of the cleaning liquid rather than the flocculated sediment layer when the surface is cleaned, thus ensuring the effective cleaning operation. At the same time, under the action of the counterweight 606, the second slider 605 slides down along the inner wall of the second slide groove 305 (according to the attached figure, it can be seen that the second slider 605 moves in the lower right direction, which can ensure that the entire filter belt 5 always maintains a stable tension state and avoids slack).

[0048] When the first slider 602 drives the lower rotating rod 8 and the filter belt 5 on it to rise, the storage box 607 descends together with the counterweight 606. In order to avoid interference between the storage box 607 and the filter belt 5, the second electric push rod 10 is activated, which drives the storage box 607 to move upward, so that it is always above the filter belt 5, thereby ensuring that the filter belt 5 can deform smoothly. After part of the cleaned filter belt 5 leaves the cleaning liquid, it will come into contact with the filtered air, and then its surface will be dried, waiting for the rotation to switch.

[0049] One of the adapter pipes 12 (connected to the input end of the suction pump 11) has several suction ports installed at its bottom and is fixed to the bottom wall of the cleaning chamber. The other adapter pipe 12 (connected to the output end of the suction pump 11) extends into the storage box 607. It is used to suck up and transfer the flocculated sediment layer into the storage box 607 after the suction pump 11 starts the suction operation. This increases the counterweight effect and reduces the interference of the flocculated sediment layer in the cleaning chamber on the cleaning filter belt 5. In response to the phenomenon that the cleaning liquid level in the cleaning chamber drops after the flocculated sediment layer is sucked up, the cleaning liquid can be replenished after suction (or a drain pipe can be installed at the bottom of the storage box 607 and the end of the drain pipe can be extended to the outside of the filter cabinet 300).

[0050] During the above process, the limiting rod 7 is mainly used to prevent the first slider 602 from rising excessively, ensuring that the filter belt 5 always forms an effective filtration area at the vent.

[0051] In this way, by dynamically switching the distance between the two lower rotating rods 8 through the switching component, the cross-sectional shape of the filter belt 5 can be adjusted, allowing the filter belt 5 immersed in the cleaning solution to switch the immersion depth in a timely manner, thereby achieving continuous and effective cleaning and unblocking operations. This ensures that the operating resistance of the fan component 303 will not increase due to the filter belt 5 failing to be unblocked in time, thus achieving energy-saving control.

[0052] Example 2:

[0053] Please see Figures 10-12 The surfaces of the two sliders 602 that are close to each other are fixed with baffle plates 13. The lower rotating rod 8 and the bracket rod 604 on the surface of the slider 602 both pass through the interior of the baffle plate 13. The side surface of the baffle plate 13 away from the slider 602 is in contact with the edge of the filter belt 5.

[0054] The barrier plate 13 has a constraint groove 132 inside, and a telescopic sleeve plate 131 is installed inside the constraint groove 132. A spring for resetting is installed inside the telescopic sleeve plate 131 (the telescopic sleeve plate 131 is made of two plates with different cross-sectional widths and hollow interiors, one of which is slidably connected to the interior of the other plate, and the spring is used to connect the two plates, which is existing technology and will not be described in detail here).

[0055] The inner wall of the constraint groove 132 is provided with an inner recess, and both sides of the telescopic sleeve 131 are slidably fitted into the inside of the inner recess.

[0056] Specifically, during the filtration process in Example 1, because the cross-sectional width of the filter belt 5 is smaller than the cross-sectional width of the cleaning chamber (the cross-sectional width of the cleaning chamber is the same as that of the filter cabinet 300), during immersion cleaning, some of the liquid containing blockages will slosh and diffuse into the area outside the filter belt 5 within the cleaning chamber through the diffusion of the liquid, and then transfer and diffuse to the inner surface of the filter belt 5, thus limiting the cleaning quality. Figure 9 As shown.

[0057] To improve the above problems, this embodiment is adopted. Based on embodiment 1, this embodiment adds a baffle plate 13. In the initial state, the end of the baffle plate 13 is located below the second slider 605, which can play a corresponding side-blocking effect on the immersion area of ​​the filter belt 5, and prevent the sewage after washing from transferring and spreading to the inside of the filter belt 5 during the immersion washing process.

[0058] Please see Figure 13As slider 602 rises, limit rod 7 contacts the top of telescopic sleeve 131 first. At this time, limit rod 7 exerts a squeezing effect on telescopic sleeve 131, causing it to be compressed. However, because part of its area is located inside the recessed groove, it still effectively encloses the constraint groove 132, making it difficult for cleaning fluid to enter the inner side of filter belt 5 through barrier plate 13. At the same time, the rise of slider 602 causes slider 605 to move diagonally downward, so that barrier plate 13 will not be blocked by slider 605 when it moves upward. In addition, to avoid storage box 607 from limiting barrier plate 13, electric actuator 10 can continue to extend, so that barrier plate 13 has enough space to move upward (because slider 602 and slider 605 are both located on the same plane, and traction rope 603 is located outside barrier plate 13, barrier plate 13 will not be blocked or interfered with by traction rope 603 when it rises).

[0059] The above description is merely a preferred embodiment of the present invention; it encompasses all the protection scope of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and improved concepts of the present invention, should be covered within the protection scope of the present invention.
