Description

Technical Field

[0001] This utility model relates to the field of spraying / polishing / dust removal, specifically a baffle protection rotating device. Background Technology

[0002] During powder coating, the powder spraying chamber needs an exhaust filtration system to ensure airflow from the workpiece inlet and powder spraying window into the chamber. This prevents powder sprayed from the spray gun from splashing back inside the chamber and avoids it from flying out of the powder spraying window and workpiece inlet, causing pollution. However, after a period of use, dust accumulates on the filter membrane of the filter cartridge, clogging the entire cartridge and hindering airflow through the membrane, thus failing to achieve the desired filtration effect. Therefore, a jet-rotating device needs to be installed inside the filter cartridge, periodically activated to blow air outwards in reverse to clean the paint powder adhering to the filter cartridge surface. This jet-rotating device includes rotating components, but existing models often have rotating components that are not smooth enough, resulting in uneven exhaust. Gas and dust can easily enter the bearings through gaps, increasing friction and expelling lubricating oil, causing the rotating components to rotate unevenly. This necessitates frequent bearing replacement or cleaning and maintenance, presenting a certain inconvenience. Summary of the Invention

[0003] The present invention addresses the shortcomings of traditional rotary jet devices, such as uneven rotation of rotating components, uneven exhaust, and the inability of gas and dust to enter the bearing from the bearing gaps when the device stops, increasing friction and causing lubricating oil to be blown out during operation, leading to uneven rotation and frequent bearing replacement or cleaning. The rotary jet device includes a first positioning part that accommodates the bearing and a baffle plate, allowing for adjustable fit between the baffle plate and the bearing to protect the bearing from dust and prevent dust from entering when rotation stops (i.e., when no gas is being emitted). The baffle plate positioning part is equipped with a baffle plate to reduce the direct impact of gas on the bearing and prevent gas from entering the bearing, thus protecting the rotating bearing. An exhaust groove connects the first positioning part and the baffle plate positioning part, allowing the exhaust rod to be inserted into the bearing inner hole and the baffle plate inner hole. The gas in the gap between the outer diameters is depressurized to prevent the gas inside the rotating device from being trapped and causing the bearing to be difficult to rotate. The gas enters through the air guide rod, passes through the rotating device, and is ejected from the air holes of the dust removal pipe. The reaction force of the high-speed gas pushes the rotating component to rotate smoothly. The rotating component drives the dust removal pipe to rotate automatically, and the high-speed airflow removes dust and other particles attached to the surface of the filter cartridge. During use, the smooth rotation can protect the bearing from dust and allow the gas inside the rotating device to be discharged, further improving the smoothness of rotation, making it more stable during use, and reducing maintenance costs.

[0004] The technical solution adopted by this utility model to solve the technical problem is: a baffle protection rotating device, including a rotating component, the rotating component including a housing composed of a front shell and a rear shell, the housing being provided with a first positioning part for accommodating a bearing and a baffle, the bearing and the baffle being installed in the first positioning part, the first positioning part being adjacent to a baffle positioning part, and the baffle being installed in the baffle positioning part.

[0005] Rotating arms are provided on both sides of the housing, and dust removal pipes are provided at the ends of the rotating arms. The channels of the rotating arms are connected to the air inlets of the dust removal pipes, which are provided with several air jet holes. When a fixing rod is inserted into the bearing bore and the baffle bore inside the housing, gas is introduced into the through hole at the upper end of the fixing rod. The gas can enter the channel of the rotating arm through the air outlet of the fixing rod, and then be ejected from the air jet holes of the dust removal pipe. When the dust removal pipes of the rotating arms on both sides eject gas, the rotating components are pushed by the gas reaction force to rotate the dust removal pipes.

[0006] A partition rib is provided between the baffle positioning part and the first positioning part of the housing. The partition rib separates the first positioning part from the baffle positioning part. The baffle is installed in the baffle positioning part, and the partition rib supports the baffle.

[0007] The housing is provided with an exhaust groove connecting the first positioning part and the baffle positioning part. A fixing rod can be inserted into the inner hole of the bearing and the inner hole of the baffle. The exhaust groove can discharge the gas in the gap between the inner hole of the baffle and the outer diameter of the fixing rod.

[0008] The lower end of the housing of the rotating component is provided with a clamping part, and a connecting pipe is installed in the clamping part. The upper and lower ends of the connecting pipe are respectively connected to the clamping part of the rotating component. The two rotating components and the connecting pipe are connected as one unit to form a rotating device. The gas entering the connecting pipe will flow into the two rotating components and then flow into the air hole of the dust removal pipe and be sprayed out.

[0009] When the fixed rod is inserted into the bearing inner hole and the baffle inner hole of the rotating component, it forms an integral baffle protection rotating device. A high-pressure air pipe is connected to the upper end of the fixed rod. When high-pressure gas is input, the gas is injected through the through hole of the fixed rod, flows out from the air outlet, enters the rotating component or enters the connecting pipe, and then enters the dust removal pipe through the channel of the rotating arm. It is then ejected from the air jet hole of the dust removal pipe. That is, the gas flowing out of the through hole of the fixed rod can flow to the channel of the rotating arm, then enter the dust removal pipe through the air inlet, and then be ejected from several air jet holes of the dust removal pipe. When the gas is ejected from the air holes, the two dust removal pipes will push the rotating component and the dust removal pipe to rotate under the action of the gas reaction force. The high-speed airflow ejected from the air holes of the dust removal pipe blows air onto the filter membrane, causing the dust attached to the filter membrane to fall off.

[0010] Alternatively, in a preferred embodiment, the upper and lower parts of the housing are respectively provided with the same first positioning part, partition rib, baffle positioning part, and exhaust groove.

[0011] The baffle installed in the first positioning part on the upper part of the housing is located at the upper end of the bearing, which shields and protects the upper end face of the bearing. When the rotating device is not started, it can prevent dust in the spraying chamber from falling onto the upper end face of the bearing or entering the bearing from the bearing gap on the upper end face.

[0012] The baffle installed in the first positioning part at the lower part of the housing is located at the upper end of the bearing, which protects the upper end face of the bearing. The lower end of the bearing is provided with a retaining spring connected to the retaining groove of the fixing rod. The retaining spring protects the lower end of the bearing, which can not only protect against dust, but also position (limit) the bearing in the vertical direction, making the rotating device smoother during rotation.

[0013] When the fixed rod can be inserted into the bearing inner hole and baffle inner hole of the rotating component, the air outlet of the fixed rod is located in the middle of the bearing at the upper and lower ends of the rotating component. Gas can enter the corresponding rotating component from the air outlet of the fixed rod, and then enter the dust removal pipe through the channel of the rotating arm and then be ejected from the jet hole. Under the action of the gas reverse force, the two dust removal pipes will push the rotating component and the dust removal pipe to rotate. The rotating component drives the dust removal pipe to rotate automatically and spray high-speed airflow to remove dust and other particles attached to the surface of the filter cartridge.

[0014] One rotating component can be connected to two dust collection pipes. A fixing rod is inserted into the bearing bore and baffle bore of the rotating component. A retaining spring is located below the lower bearing of the rotating component and connects to the retaining rod's groove, thus confining the rotating component within the fixing rod, forming an integrated baffle protection rotating device. Alternatively, a baffle protection rotating device can consist of two rotating components: an upper rotating component and a lower rotating component. The left and right sides of both rotating components are connected to dust collection pipes respectively. The same fixing rod is inserted into the bearing bore and baffle bore of both rotating components. A retaining spring is located below the lower bearing of each rotating component and connects to the retaining rod's groove, thus confining the rotating component within the fixing rod, forming an integrated baffle protection rotating device with two rotating components.

[0015] The beneficial effects of this utility model are: a baffle protection rotating device, comprising a housing composed of a front shell and a rear shell, wherein a first positioning part is provided in the housing to accommodate a bearing and a baffle. The baffle cooperates with the bearing to provide dust protection, preventing dust from entering the bearing. The baffle positioning part cooperates with the baffle to reduce the direct impact of gas on the bearing and prevent gas from entering the bearing. A rib is provided to separate the first positioning part from the baffle positioning part, supporting the baffle and preventing the baffle from squeezing the bearing under air pressure, thus increasing bearing resistance. An exhaust groove is provided in the housing to connect the first positioning part and the baffle positioning part. A fixing rod can be inserted into the inner hole of the bearing and the inner hole of the baffle. The venting groove can release the gas in the gap between the inner hole of the baffle and the outer diameter of the fixing rod. During use, the rotation is smooth. A retaining ring is set to cooperate with the bearing to shield and protect the lower end of the bearing. It can play a role in dust protection and limit the vertical direction of the bearing. The rotating device is smoother during rotation, realizing dust protection, venting, and reducing the direct action of gas on the bearing. It further improves the smoothness of the rotation of the baffle protection rotating device, making it more stable during use, with good cleaning effect and reduced maintenance costs. The front and rear shells are easy to manufacture, reducing manufacturing costs. Attached Figure Description

[0025] exist Figure 1-3 In the illustrated embodiment, a rotating component includes an integral housing 1 composed of a front shell and a rear shell with identical structures. The housing 1 has a first positioning part 2 that accommodates a bearing 4 and a baffle 3. The bearing 4 and the baffle 3 can be installed in the first positioning part 2. The first positioning part 2 accommodates the bearing 4 and the baffle 3, allowing the baffle 3 to cooperate with the bearing 4, providing dust protection for the bearing 4 and preventing dust from entering the bearing 4 when rotation stops (i.e., when no air is being expelled). Adjacent to the first positioning part 2 is a baffle positioning part 8. A partition rib 7 separates the first positioning part 2 from the baffle positioning part 8. The baffle 3 is installed in the baffle positioning part 8, reducing the direct impact of gas on the bearing 4 and preventing gas from entering the bearing 4, thus protecting the rotating bearing 4. The partition rib 7 supports the baffle 3, preventing the baffle 3 from squeezing the bearing 4 under air pressure, which would increase the bearing 4's resistance.

[0026] One or more baffles 3 can be installed in the baffle positioning part 8.

[0027] The housing 1 is provided with an exhaust groove 5 connecting the first positioning part 2 and the baffle positioning part 8. A fixing rod 14 can be inserted into the inner hole of the bearing 4 and the inner hole of the baffle 3. The exhaust groove 5 can discharge the gas in the gap between the inner hole of the baffle 3 and the outer diameter (outer wall) of the fixing rod 14.

[0028] Rotating arms 6 are provided on both sides of the housing 1. Dust removal pipes 11 are provided at the ends of the rotating arms 6. The rotating arms 6 are provided with channels that communicate with the air inlets of the dust removal pipes 11. The dust removal pipes 11 are provided with several vertically arranged jet holes. An angle is provided between the jet holes and the rotating arms. The upper and lower ends of the dust removal pipes 11 are closed ends. When the fixing rod 14 is inserted into the inner hole of the bearing 4 and the inner hole of the baffle 3 inside the housing 1, gas is input into the through hole at the upper end of the fixing rod 14. The gas can enter the channel of the rotating arms 6 from the air outlet of the fixing rod 14 and then be ejected from the jet holes of the dust removal pipes 11. When the dust removal pipes 11 of the left and right rotating arms 6 are ejected, the rotating components are pushed by the gas reverse force to drive the dust removal pipes 11 to rotate.

[0029] The lower end of the housing 1 of the rotating component is provided with a clamping tube 9, and a connecting tube 10 is installed in the clamping tube 9. The upper and lower ends of the connecting tube 10 are respectively connected to the clamping tube 9 of the rotating component. The two rotating components and the connecting tube 10 are connected as a whole to form an integral rotating device. The gas entering the connecting tube 10 will flow into the two rotating components and then flow into the air hole of the dust removal pipe 11 and be sprayed out.

[0030] exist Figure 4 In the illustrated embodiment, when the fixing rod 14 is inserted into the inner hole of the bearing 4 and the inner hole of the baffle 3 of the rotating component, an integral baffle protection rotation device is formed. A high-pressure air pipe is connected to the upper end of the fixing rod 14. When high-pressure gas is input, the gas is injected through the through hole of the fixing rod 14, flows out from the air outlet, enters the rotating component or the connecting pipe 10, and then enters the dust removal pipe 11 through the channel of the rotating arm 6. It is then sprayed out from the air jet hole of the dust removal pipe 11. That is, the gas flowing out from the through hole of the fixing rod 14 can flow to the channel of the rotating arm 6, and then enter the dust removal pipe 11 through the air inlet. Inside the dust removal pipe 11, gas is ejected from several air jet holes. When the gas is ejected from the air holes, the two dust removal pipes 11 will drive the rotating component and the dust removal pipe 11 to rotate under the action of the gas reverse force. The high-speed airflow ejected from the air holes of the dust removal pipe 11 blows air onto the filter membrane, causing the dust attached to the filter membrane to fall off. This can reduce the direct impact of gas on the bearing and prevent gas from entering the bearing. It can also prevent the baffle from squeezing the bearing, which would increase the bearing resistance. In addition, it can discharge the gas in the gap between the inner hole of the baffle and the outer diameter of the fixed rod. During use, the rotation is smooth.

[0031] exist Figure 5-7In the second embodiment shown, the upper and lower parts of the housing 1 are respectively provided with the same first positioning part 2, partition 7, baffle positioning part 8, and exhaust groove 5.

[0032] The baffle 3 installed in the first positioning part 2 on the upper part of the housing 1 is located at the upper end of the bearing 4, which shields and protects the upper end surface of the bearing 4. When the rotating device is not started, it can prevent dust in the spraying chamber from falling onto the upper end surface of the bearing 4 or entering the bearing 4 from the gap of the upper end surface of the bearing 4.

[0033] The baffle 3 installed in the first positioning part 2 at the lower part of the housing 1 is located at the upper end of the bearing 4, which protects the upper end surface of the bearing 4. The lower end of the bearing 4 is provided with a retaining spring 13 connected to the retaining groove of the fixing rod 14. The retaining spring 13 protects the lower end of the bearing 4, which can both prevent dust and limit the vertical direction of the bearing 4, making the rotating device rotate more smoothly.

[0034] exist Figure 7 In the illustrated embodiment, a baffle protection rotating device comprises two rotating components: an upper rotating component and a lower rotating component. The left and right sides of the two rotating components are respectively connected to the dust removal pipe 11. The fixed rod 14 is provided with an air outlet. The fixed rod 14 can be inserted into the inner hole of the bearing 4 and the inner hole of the baffle 3 of the two rotating components. The air outlet of the fixed rod 14 is located at the middle of the bearing at the upper and lower ends of each rotating component. Gas can enter the corresponding rotating component from the air outlet of the fixed rod 11, and then enter the dust removal pipe 11 through the channel of the rotating arm 6 and then be ejected from the air jet hole. Under the action of the gas reverse force, the two dust removal pipes 11 will push the rotating components and dust removal pipes 11 to rotate. The rotating components drive the dust removal pipes to rotate automatically and spray high-speed airflow to remove dust and other particles attached to the surface of the filter cartridge. The baffle 3 cooperates with the bearing 4 to protect the bearing 4 from dust, preventing dust from entering the bearing 4 when it stops rotating (i.e., when it is not expelling gas). The baffle 3 is installed in the baffle positioning part 8 to reduce the direct impact of gas on the bearing 4 and prevent gas from entering the bearing 4, thus protecting the rotating bearing 4. The baffle 7 supports the baffle 3 to prevent the baffle 3 from squeezing the bearing 4 under the action of air pressure, which would increase the resistance of the bearing 4. The exhaust groove 5 can discharge the gas in the gap between the inner hole of the baffle 3 and the outer diameter (outer wall) of the fixing rod 14. A snap ring is also provided to cooperate with the bearing to shield and protect the lower end of the bearing. It can play a role in dust protection and limit the vertical direction of the bearing. The rotating device is smoother during rotation, which can protect the bearing from dust, exhaust gas, reduce the direct action of gas on the bearing, further improve the smoothness of rotation, make it more stable during use, reduce maintenance costs, and facilitate installation and manufacturing, thus reducing manufacturing costs.

[0035] It is not fixed. It can be a rotating part connected to two dust removal pipes 11. A fixing rod 14 is inserted into the inner hole of the bearing 4 and the inner hole of the baffle 3 of the rotating part. Then, a snap ring 13 is provided below the bearing 4 at the lower end of the rotating part and connected to the snap groove of the fixing rod 14 to limit the rotating part in the fixing rod 14, thus forming an integral baffle protection rotating device.
