[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Please also refer to Figures 1 to 2 The present invention now provides a gas Roots blower bearing dissipation device. The gas Roots blower bearing dissipation device is provided with an air hole 42 at the cylinder bearing 41 of the Roots blower 4, and includes multiple exhaust pipes 1, an exhaust fan 2, and a filter dust collector 3. One end of the multiple exhaust pipes 1 is connected to the air hole 42 so that the gas in the bearing 41 can enter the air hole 42, and the other end is placed outside the pressure station room, and is used to transport the gas leaked from the cylinder bearing 41 of the Roots blower 4 to the outside to disperse the bearing 41; the exhaust end of the exhaust fan 2 is directed toward the cylinder bearing 41 of the Roots blower 4, and the air outlet end is connected to the exhaust pipe 1. The exhaust fan 2 is used to extract the gas leaked from the cylinder bearing 41 of the Roots blower 4 into the exhaust pipe 1; the filter dust collector 3 is arranged outside the pressure station room and is connected to the output end of the exhaust pipe 1, and is used to filter and remove dust from the gas output from the exhaust pipe 1.

[0026] The present invention provides a gas Roots blower bearing dispersing device. Compared with the prior art, an air hole 42 is provided at the cylinder bearing 41 of the Roots blower 4. One end of a plurality of exhaust pipes 1 is connected to the air hole 42 so that the gas in the bearing 41 can enter the air hole 42. The other end is placed outside the pressurizing station to transport the gas leaked from the cylinder bearing 41 of the Roots blower 4 to the outside to disperse the bearing 41. The exhaust end of the exhaust fan 2 is directed toward the cylinder bearing 41 of the Roots blower 4, and the air outlet end is connected to the exhaust pipe 1. The exhaust fan 2 is used to extract The gas leaked from the cylinder bearing 41 of the Roots blower 4 is taken into the exhaust pipe 1; the filter dust collector 3 is arranged outside the pressure station room and is connected to the output end of the exhaust pipe 1, and is used to filter and remove dust from the gas output from the exhaust pipe 1, solving the technical problem in the prior art that the bearing 41 of the Roots blower 4 cannot be discharged, resulting in gas leakage and gas poisoning to personnel. The technical effect is that the bearing 41 of the Roots blower 4 can be discharged, gas leakage and gas poisoning can be prevented, and the health of personnel can be guaranteed.

[0027] The air hole 42 is provided on the circumferential outer wall of the bearing 41, and can be interconnected with the interior of the bearing 41, that is, the gas inside the bearing 41 can be discharged into the exhaust pipe 1 through the air hole 42, thereby realizing the output of the gas to the outside, and will not cause gas leakage in the boosting station. If there is one air hole 42, then one exhaust pipe 1 is provided. If there are multiple air holes 42, then multiple exhaust pipes 1 are provided. In this embodiment, because the Roots blower 4 has two cylinder bearings 41, at least two exhaust pipes 1 are provided, both of which can realize the function of outputting the gas to the outside, ensuring that there will be no gas leakage and the like in the boosting station room, and ensuring the health and safety of personnel. There is at least one exhaust fan 2, and preferably, at least one exhaust fan 2 is provided at each bearing 41.

[0028] Preferably, a plurality of gas alarms 5 can be installed in the boosting station. If a gas leak occurs, the staff can be alerted immediately and moved outdoors. The gas alarm 5 is very sensitive, which can also prevent people from being poisoned.

[0029] In some embodiments, see Figures 1 to 2 The cylinder bearing 41 of the Roots blower 4 has a plurality of air holes 42 evenly distributed along its circumference, and the plurality of exhaust pipes 1 are sealed and connected to the plurality of air holes 42 in a one-to-one correspondence. Figure 2 In the figure, six air holes 42 are indicated on a bearing 41 , and the six air holes 42 are all connected to the exhaust pipe 1 . The exhaust pipe 1 is a rigid component and will not be compressed or deformed, thereby ensuring the gas circulation effect.

[0030] Specifically, if the diameter of the air hole 42 is 10 mm, the diameter of the exhaust pipe 1 should be set to correspond to the diameter so that the two can be assembled together without gas leakage.

[0031] In order to facilitate the connection between the exhaust pipe 1 and the filter dust collector 3, in some embodiments, refer to Figures 1 to 2 The gas Roots blower bearing dissipation device further includes a main pipe 6, one end of which is connected to the output ends of multiple exhaust pipes 1, and the other end is connected to the air inlet end of the filter dust collector 3. The inner diameter of the main pipe 6 is larger than the inner diameter of the exhaust pipe 1. By using the main pipe 6, only one pipe can be used to meet the usage requirements. A three-way or multi-way joint can be provided at one end of the main pipe 6. In short, the gas in multiple exhaust pipes 1 can flow into the main pipe 6, so that the other end of the main pipe 6 can be easily connected or communicated with the filter dust collector 3.

[0032] In order to be able to timely detect whether there is a gas leak, in some embodiments, refer to Figures 1 to 2A gas leak detector 7 is installed on the exhaust pipe 1 near the cylinder bearing 41 of the Roots blower 4. The gas leak detector 7 has an alarm module. When a gas leak is detected, the gas leak detector 7 issues an alarm signal. The gas leak detector 7 is located near the bearing 41. When a gas leak occurs at the bearing 41, it can be detected immediately and an alarm signal can be issued. This can alert staff and eliminate the danger in a timely manner. The gas leak detector 7 in this embodiment adopts the existing technology products, but it can achieve timely and real-time gas monitoring.

[0033] In order to achieve remote control of the exhaust fan 2, in some embodiments, see Figures 1 to 2 The exhaust fan 2 is connected to a wireless communication module, and the gas Roots blower bearing release device also includes a mobile terminal 8 that is wirelessly connected to the exhaust fan 2. The mobile terminal 8 is used to remotely control the operation of the exhaust fan 2. The exhaust fan 2 can be controlled by the mobile terminal 8, and the control can be achieved without the need for personnel to personally enter the pressure plate, which is convenient for the staff. In addition, there is a display on the mobile terminal 8. The gas leak detector 7 is remotely connected to the mobile terminal 8 (that is, the gas leak detector 7 is also provided with a wireless communication module, which can realize wireless communication or communication with external equipment). Moreover, the display can show whether there is a gas leak at present, which is convenient for the staff to know at the first time and facilitate subsequent processing.

[0034] In some embodiments, see Figures 1 to 2 The filter dust collector 3 includes a gas filter 31 and a gas dust collector 32, which are arranged in sequence along the gas flow direction on the exhaust pipe 1 (i.e., filtering is performed first, then dust removal). The gas filter 31 and the gas dust collector 32 are both electrically connected to a controller 33, and their operation is controlled by the controller 33. In this embodiment, the gas dust collector 32 can be selected from a variety of options, such as a gravity dust collector, a cyclone dust collector, a bag dust collector, an electrostatic dust collector, etc. The gas filter 31 can filter impurities in the gas. Various types of products are available in the prior art, all of which can achieve the above functions.

[0035] When gas passes through the gap between the exhaust pipe 1 and the air hole 42 (the outer wall of the bearing 41), or when gas leaks, in order to immediately block the gap or leak, in some embodiments, refer to Figures 1 to 2A collar 9 is coaxially sleeved on the cylinder bearing 41 of the Roots blower 4. The collar 9 is arranged away from the exhaust pipe 1. The collar 9 includes a left ring 91 and a right ring 92 that are detachably connected to each other. Multiple groups of sealants 93 are evenly distributed on the inner circumferential surfaces of the left ring 91 and the right ring 92. A glue gun 94 is detachably connected to the left ring 91 or the right ring 92. After the sealant 93 is loaded into the glue gun 94, it is used to seal the gas leakage between the bearing 41 of the Roots blower 4 and the exhaust pipe 1. In the radial direction of the bearing 41, the collar 9 does not block the air hole 42 or the exhaust pipe 1, that is, it does not affect the normal extraction of the exhaust pipe 1. The collar 9 does not need to be coaxial with the bearing 41. The left ring 91 and the right ring 92 are two independent components that can be combined and spliced ​​together to form a "collar 9 structure". When a gas leak occurs somewhere, the sealant 93 can be blocked by the glue gun 94 and the sealant 93, achieving the technical effect of preventing blockage and leakage immediately, and can fully prevent gas leakage or reduce the amount of leakage. In this embodiment, the glue gun 94 is connected to the right ring 92 by a rope.

[0036] Specifically, bags are provided on both the left ring 91 and the right ring 92, and sealant 93 is contained within the bags. During use, sealant 93 is removed from the bags and loaded onto a sealant gun 94. By squeezing or pressing the sealant gun 94, sealant 93 is applied to the gas leak. This method is simple and convenient, and provides a good leak-proof seal. If six air holes 42 are provided, at least three sets of sealant 93 should be provided. The rule for placement is that the sealant 93 should be positioned close to the air holes 42. This allows for smoother and more flexible operation, improving efficiency.

[0037] Specifically, the left ring 91 and the right ring 92 can be connected by components or fasteners or connectors such as buckles, bolts, etc. The weight of the collar 9 is relatively light and will not affect the bearing 41. Its inner diameter is larger than the outer diameter of the bearing 41. Figure 3 The bearing 42 located below is not shown in the figure. According to the specific structure of the Roots blower 4 product in the prior art, it can be seen that a Roots blower 4 includes two sets of bearings 42.

[0038] In some embodiments, see Figures 1 to 2 The discharge end of the filter dust collector 3 is connected to a gas recovery system 10, which is used to recover and reuse the filtered and dust-removed gas. The gas recovery system 10 can reduce production costs and improve overall competitiveness. The filtered and dust-removed gas is easy to recycle. The recovered gas has high pressure and calorific value, and its excess pressure and calorific value can be utilized. Currently, there are many methods to utilize these, such as using excess pressure to generate electricity, which can save energy, reduce costs and increase efficiency.

[0039] In order to achieve the flexible adjustment of the exhaust position and exhaust direction (orientation) of the exhaust fan 2, in some embodiments, refer to Figures 1 to 2 A mobile trolley 11 is provided on the ground where the Roots blower 4 is placed. An electric rotating platform 12 is provided on the mobile trolley 11. The upper end of the electric rotating platform 12 is a rotating end and can rotate circumferentially in a horizontal plane. The exhaust fan 2 is provided at the rotating end. The exhaust position of the exhaust fan 2 is adjusted by moving the mobile trolley 11, and the exhaust direction is adjusted by rotating the electric rotating platform 12. The position of the exhaust fan 2 can be adjusted by the mobile trolley 11 so that the exhaust fan 2 is placed close to the bearing 41. By controlling the rotation of the electric rotating platform 12, the exhaust direction of the exhaust fan 2 can be adjusted so that it is always directed towards the bearing 41, thereby ensuring the gas dissipation effect of the bearing 41.

[0040] The bottom of the mobile car 11 is provided with a battery and a drive motor, and the power output end of the drive motor is connected to a wheel, so as to drive the mobile car 11 to move. The battery is required to supply power to the drive motor, and the battery can be charged and discharged infinitely.

[0041] In some embodiments, see Figures 1 to 2 A photovoltaic power supply component 13 is provided outdoors at the boosting station. The power output end of the photovoltaic power supply component 13 is electrically connected to the exhaust fan 2 and the filter dust collector 3, respectively, and is used to supply power to the exhaust fan 2 and the filter dust collector 3, respectively. The power output end of the photovoltaic power supply component 13 is also connected to the power supply end of the gas leak monitor 7, so that it can supply power to it, avoiding the use of commercial power and the situation where it cannot be powered or used when there is no power. The power output end of the volt power supply component is also electrically connected to the battery of the mobile trolley 11 and the electric rotating table 12, and supplies power to both of them respectively. The power output end of the photovoltaic power supply component 13 is also electrically connected to the gas filter 31 and the gas dust collector 32 and supplies power.

[0042] Specifically, the photovoltaic power supply assembly 13 in this embodiment includes a solar panel, etc., which can fully absorb sunlight energy and convert it into electrical energy to power the load in the present invention, thereby avoiding the situation where the load cannot be powered or used when the mains is used and no power is available.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
