Description

Technical Field

[0001] This invention relates to the field of waste gas purification, and more particularly to a building waste gas purification device. Background Technology

[0002] Construction exhaust gases are generated during the construction process due to the operation of machinery and equipment. They contain a significant amount of heat and particulate matter, which can easily affect the health of construction workers and also have a considerable impact on the construction site environment.

[0003] In existing technologies, construction exhaust gas is generally treated using filtration and humidification devices, which is costly. Furthermore, at construction sites, workers often use electric fans for heat dissipation and cooling, but these fans are easily contaminated by dust and particulate matter in the exhaust gas, resulting in high dust content in the blown air and impacting worker health. Therefore, based on these considerations, this application designs a construction exhaust gas purification device that integrates filtration, humidification, and a fan. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a building exhaust gas purification device.

[0005] A building exhaust gas purification device, comprising:

[0006] A purification box, wherein a negative pressure port is provided on the side of the purification box, a negative pressure pump is provided in the negative pressure port, and a filter assembly and a cleaning assembly for cleaning the filter assembly are connected inside the purification box;

[0007] A connecting platform, which is fixed to the bottom of the purification box;

[0008] A base platform is connected to a water inlet pipe, which inputs cooling water into a water cavity opened in the base platform. The connecting platform is connected to the base platform by multiple heat dissipation pipe assemblies. The heat dissipation pipe assemblies are configured as a retractable structure, wherein the portions of the multiple heat dissipation pipe assemblies between the base platform and the connecting platform can be retracted into the interior of the base platform, thereby making the base platform and the connecting platform a whole. An auxiliary heat dissipation assembly is provided in the base platform.

[0009] An air outlet is fixed on the side of the purification box away from the negative pressure port and has heat dissipation fins inside. The air outlet is connected to a water chamber in the base through a pipe.

[0010] In the aforementioned building exhaust gas purification device, the filter assembly includes a rotating cylinder. A layered plate is rotatably connected to the top of the rotating cylinder. The layered plate is fixedly connected to the inner top wall of the purification chamber. The layered plate divides the space inside the purification chamber into a purification space and a drive space. The drive space is located above the layered plate. A rotating motor is installed in the drive space. The rotating motor is fixed to the upper end face of the layered plate by a mounting bracket. The output shaft of the rotating motor is connected to a rotating shaft. The rotating shaft is coaxial with the rotating cylinder and extends through to the bottom of the rotating cylinder. Multiple connection ports are circumferentially opened on the outer side wall of the rotating cylinder. Each connection port is sealed and fixedly connected to a filter screen.

[0011] In the above-mentioned building exhaust gas purification device, the bottom of the purification box is provided with an air outlet that matches the size of the rotating drum, the bottom of the rotating drum is provided with an opening that connects to the distribution space inside the connecting platform, and the tops of the multiple heat dissipation pipe assemblies connect to the distribution space.

[0012] In the aforementioned building exhaust gas purification device, multiple heat dissipation pipe assemblies are arranged in a ring on the outside of the base platform. A circular connecting groove is opened on the top of the base platform, and the auxiliary heat dissipation assembly is installed in the connecting groove. The heat dissipation pipe assembly is connected to the water cavity.

[0013] In the aforementioned building exhaust gas purification device, the heat dissipation pipe assembly includes an inner pipe and an outer pipe that are connected in a mating manner. The two ends of the outer pipe are respectively fixedly connected to the upper and lower sides of the water chamber. A circular ring is sleeved on the outer bottom of the outer pipe, and multiple square limiting blocks are fixedly connected to the lower side of the circular ring. Multiple limiting grooves that mate with the limiting blocks are opened on the inner wall of the inner pipe. An arc-shaped groove is provided at the top of each limiting groove, and the height of the arc-shaped groove matches the height of the limiting block. An exhaust pipe is connected to the bottom of the outer pipe, and an electromagnetic one-way valve is sealed in the exhaust pipe.

[0014] In the above-mentioned building exhaust gas purification device, a threaded layer is provided on the upper side of the ring, and a nut is threadedly connected to the threaded layer. The nut is connected to the threaded layer and is connected to the upper end face of the base when the limiting block is engaged with the arc groove. The bottom of the connecting platform is provided with multiple receiving grooves that are engaged with the nut.

[0015] In the aforementioned building exhaust gas purification device, the auxiliary heat dissipation assembly includes heat dissipation blade one and heat dissipation blade two disposed in the connecting groove. Both are connected to a lifting assembly. The lifting assembly includes an outer cylinder sleeved on the outside of the rotating shaft. The outer cylinder is rotatably connected to the center of the connecting groove opened in the base platform. Heat dissipation blade one is fixedly connected to the side wall of the outer cylinder. An inner cylinder is fitted to the inner side of the outer cylinder. The inner side of the inner cylinder is fitted with the rotating shaft. Heat dissipation blade two is fixedly connected to the outer wall of the inner cylinder. A synchronous belt is connected to the bottom of the inner cylinder. A synchronous pulley is connected to each end of the synchronous belt. The other side of the synchronous belt is fixedly connected to the outer cylinder. The bottom of the rotating shaft is connected to the synchronous pulley.

[0016] In the above-mentioned building exhaust gas purification device, the cleaning component includes two cleaning plates arranged symmetrically on both sides of the negative pressure port. Each cleaning plate is vertically arranged and has a cleaning layer. The cleaning layer abuts against the outer wall of the filter screen. The inner tube is made of aluminum alloy and has irregular protrusions and grooves on its outer side.

[0017] In the above-mentioned building exhaust gas purification device, the air outlet platform is connected to an air outlet pipe, the air outlet pipe is configured as a telescopic structure, the lower part of the air outlet pipe is connected to an annular pipe, and the annular pipe is connected to the top side of the base platform through multiple branch pipes and communicates with the water chamber.

[0018] Compared with existing technologies, the advantages of this invention are:

[0019] 1. In use, this invention draws in outside air into the purification chamber, filters and removes dust, and then feeds it into the bottom heat dissipation pipe assembly and water chamber for cooling and humidification. The air is then output from the air outlet. This not only purifies the surrounding air but also outputs humidified cool air, thereby improving the surrounding air quality and creating a comfortable construction environment. It avoids the problem of directly feeding air into the cooling water, which would cause the water temperature to rise and prevent the production of cooling gas.

[0020] 2. During use, the inner tube can be retracted to the base using the retractable heat dissipation pipe assembly. This has the advantages of facilitating the transport and movement of the device, and also allows the inner tube to be immersed in water after use to clean both the inner and outer tubes, thus reducing the risk of blockage and making subsequent use easier.

[0021] 3. During air purification, the installation of nuts and threaded layers allows multiple inner tubes to be stably mounted on the base platform, thus improving the stability of the device. Furthermore, when the heat dissipation pipe assembly extends, the lifting assembly can evenly distribute the two heat dissipation blades located in the connecting groove between the connecting groove and multiple heat dissipation pipes. This allows both to cool the base platform and the heat dissipation pipe assembly separately during rotation, improving heat exchange efficiency. Attached Figure Description

Detailed Implementation

[0034] Reference Figure 1-11 A building exhaust gas purification device includes a purification box 1, a negative pressure port 2, a negative pressure pump 3, a filter assembly 4, a connecting platform 5, a base platform 6, a heat dissipation pipe assembly 7, an auxiliary heat dissipation assembly 8, a cleaning assembly 9, and an air outlet platform 10.

[0035] The purification chamber 1 has a negative pressure port 2 on its side, and a negative pressure pump 3 is installed in the negative pressure port 2. The purification chamber 1 is internally connected to a filter assembly 4 and a cleaning assembly 9 for the cleaning filter assembly 4. The air outlet 10 is fixed on the side of the purification chamber 1 away from the negative pressure port 2 and has heat dissipation blades inside. The air outlet 10 is connected to a water chamber 63 in the base 6 through a pipe. The base 6 is connected to a water inlet pipe 61 and cool water is introduced into the water chamber 63. The connecting platform 5 is connected to the base 6 through multiple heat dissipation pipe assemblies 7. The air outlet 10 is connected to an air outlet pipe 11. The air outlet pipe 11 is designed to be retractable. The bottom of the air outlet pipe 11 is connected to an annular pipe 12. The annular pipe 12 is connected to the top side of the base 6 through multiple branch pipes 13 and communicates with the water chamber 63. In this way, after the gas enters the purification chamber 1, it is filtered by the filter assembly 4 and then enters the heat dissipation pipe assembly 7 for cooling. Then it enters the water chamber 63 in the base 6 for humidification. Finally, it enters the air outlet pipe 11 through the annular pipe 12 and is discharged, thus completing the purification function.

[0036] The filter assembly 4 includes a rotating cylinder 41. A layered plate 42 is rotatably connected to the top of the rotating cylinder 41. The layered plate 42 is fixedly connected to the inner top wall of the purification chamber 1. The layered plate 42 divides the space inside the purification chamber 1 into a purification space 101 and a drive space 102. The drive space 102 is located above the layered plate 42. A rotating motor 43 is installed in the drive space 102. The rotating motor 43 is fixed to the upper end face of the layered plate 42 by a mounting bracket 44. The output shaft of the rotating motor 43 is connected to a rotating shaft 46. The rotating shaft 46 is coaxially arranged with the rotating cylinder 41 and extends through to the bottom of the rotating cylinder 41. Multiple connection ports are circumferentially opened on the outer side wall of the rotating cylinder 41. Each connection... A filter screen 45 is fixedly connected to the port and seals it. The filter screen 45 filters the gas. Since the rotating motor 43 drives the rotating drum 41 to rotate, the filter screen 45 will be in a rotating state. This makes it easier for the particles attached to the filter screen 45 to be thrown outward, avoiding the problem of clogging the filter screen 45. The cleaning component 9 includes two cleaning plates 91 set on both sides of the negative pressure port 2. The cleaning plates 91 are set with a cleaning layer 92. The cleaning layer 92 abuts against the outer wall of the filter screen 45. This can clean the particles attached to the filter screen 45 that cannot be thrown out, and further improve the filtration effect of the filter screen 45.

[0037] The connecting platform 5 is fixed to the bottom of the purification box 1. The bottom of the purification box 1 has an air outlet that matches the size of the rotating drum 41. The bottom of the rotating drum 41 has an opening that connects to the distribution space 51 inside the connecting platform 5. The tops of multiple heat dissipation pipe assemblies 7 are connected to the distribution space 51. Multiple heat dissipation pipe assemblies 7 are arranged in a ring on the outside of the base platform 6. The top of the base platform 6 has a circular connecting groove 62. The auxiliary heat dissipation assembly 8 is arranged in the connecting groove 62. The heat dissipation pipe assembly 7 is connected to the water cavity 63 in the base platform 6.

[0038] The heat dissipation pipe assembly 7 is designed as a retractable structure, wherein the portions of multiple heat dissipation pipe assemblies 7 between the base platform 6 and the connecting platform 5 can be retracted into the interior of the base platform 6, thus making the base platform 6 and the connecting platform 5 a whole. An auxiliary heat dissipation assembly 8 is provided in the base platform 6. The heat dissipation pipe assembly 7 includes an inner tube 71 and an outer tube 72 that are connected to each other. The inner tube 71 is made of aluminum alloy, and irregular protrusions and grooves are provided on the outer side of the inner tube 71. The two ends of the outer tube 72 are respectively fixedly connected to the upper and lower sides of the water cavity 63. A ring 73 is sleeved on the outer bottom of the outer tube 72, and multiple square limiting blocks 75 are fixedly connected to the lower side of the ring 73. Multiple limiting blocks 75 are provided on the inner wall of the inner tube 71 to cooperate with the limiting blocks 75. The top of each limiting groove 76 is provided with an arc-shaped groove 77, the height of which matches the height of the limiting block 75. The bottom of the outer tube 72 is connected to an air outlet pipe 78, and an electromagnetic one-way valve is sealed in the air outlet pipe 78. The upper side of the ring 73 is provided with a threaded layer 74, and a nut 79 is threadedly connected to the threaded layer 74. The nut is connected to the threaded layer 74 and is connected to the upper end face of the base platform 6 when the limiting block 75 is engaged with the arc-shaped groove 77. The bottom of the connecting platform 5 is provided with multiple receiving grooves 710 that engage with the nut 79. The receiving grooves 710 can accommodate the nut 79 when the base platform 6 and the connecting platform 5 are in contact, so that the base platform 6 and the connecting platform 5 can be fully connected.

[0039] The auxiliary heat dissipation assembly 8 includes a first heat dissipation blade 81 and a second heat dissipation blade 82 disposed in the connecting groove 62. The first heat dissipation blade 81 is located below the second heat dissipation blade 82. Both are connected to a lifting assembly 83. The lifting assembly 83 includes an outer cylinder 831 sleeved on the outside of the rotating shaft 46. The outer cylinder 831 is rotatably connected to the center of the connecting groove 62 opened in the base platform 6. The first heat dissipation blade 81 is fixedly connected to the side wall of the outer cylinder 831. An inner cylinder 832 is fitted to the inner side of the outer cylinder 831. The inner side of the inner cylinder 832 fits with the rotating shaft 46. The second heat dissipation blade 82 is fixedly connected to the outer side wall of the inner cylinder 832. A synchronous belt 833 is connected to the bottom of the inner cylinder 832. A synchronous pulley 834 is connected to each end of the synchronous belt 833. The other side of the synchronous belt 833 is fixedly connected to the outer cylinder 831. The bottom of the rotating shaft 46 is connected to the synchronous pulley 834. The advantage of this is that it improves heat dissipation... During the actual assembly of the tube assembly 7, the connecting platform 5 located in the middle will move away from the base platform 6. Therefore, the rotating shaft 46 will move upward. The rotating shaft 46 is connected to one side of the synchronous belt 833. Therefore, the movement of the rotating shaft 46 will drive the synchronous belt 833 to move. The other side of the synchronous belt 833 is positioned by the fixed outer cylinder 831. Therefore, the synchronous belt 833 as a whole will move upward and drive the synchronous pulley 834 located on the upper side to move. The synchronous pulley 834 will drive the inner cylinder 832 to move upward, so that the outer cylinder 831, the inner cylinder 832 and the rotating shaft 46 are in an upward unfolded state. At this time, the heat dissipation blade 1 81 connected to the outer cylinder 831 is still located in the connecting groove 62, while the heat dissipation blade 2 82 connected to the inner cylinder 832 will be located between multiple inner tubes 71. Therefore, at this time, the two heat dissipation blades will cool the base platform 6 and the inner tubes 71 respectively, improving the heat exchange speed.

[0040] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative and not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
