High safety oil tank automatic pressure relief turbine fan and use method thereof

Abstract

This invention relates to the field of turbine blower technology and discloses a high-safety automatic pressure relief turbine blower for an oil tank and its usage method. The blower includes a first base, with a second base at one end of the first base, and a positioning assembly between the first and second bases. A motor is mounted on the outer surface of the top of the second base, and a pressure relief pipe is fixedly installed on the outer surface of the top of the second base, located to one side of the motor. The bottom end of the pressure relief pipe is connected to the oil tank, and a top pipe is fixedly installed at the top end of the pressure relief pipe. Through the connection between the pressure relief pipe and the oil tank, when the air pressure inside the oil tank is too high, the air pressure compresses a second return spring, pushing the top cover upwards and opening the through-hole to relieve pressure, preventing excessive air pressure inside the oil tank. After the air pressure returns to normal, the second return spring resets the top cover. The length of the second return spring can be adjusted by an adjusting ring to adjust its preload, controlling the pressure pushing the top cover and thus controlling the air pressure inside the oil tank.

Description

Technical Field

[0001] This invention relates to the field of turbine blower technology, specifically to a high-safety turbine blower with automatic oil tank depressurization and its usage method. Background Technology

[0002] The turbine fan continuously draws air from the sealed cavity, causing the internal air pressure to be lower than the external atmospheric pressure, thus creating a negative pressure. The external normal pressure air will continuously flow towards the negative pressure area, forming a directional airflow. The airflow and pressure difference work together to affect the wet paper sheet.

[0003] For example, Chinese patent CN112761976A discloses a pulp mixing turbine fan in a papermaking process. Its structure includes an air inlet, a motor, and a guide fan. The air inlet is mounted on the guide fan, and the motor is connected to the guide fan. The guide fan consists of a side decorative plate, a mounting rod, and an internal structure. The side decorative plate is connected to the mounting rod and the internal structure. The internal structure fits snugly against the mounting rod. The internal structure includes an embedded mounting plate and a spiral tube installer. The embedded mounting plate is connected to the spiral tube installer. The spiral tube installer includes a limiter, a track structure, and a spiral tube body. The limiter cooperates with the track structure, and the track structure fits snugly against the spiral tube body. The invention utilizes wind power to drive the solenoid body to slide along a track, which assists in the sliding process and reduces power consumption. The wind power drives the solenoid installer to rotate, causing the exhaust air to be delivered in a rotating manner, which changes the traditional forced air delivery method. This avoids the pulp being wrinkled and ensures the flatness of the paper. In traditional turbine blowers, the pressure in the oil tank changes constantly during use. When the pressure in the oil tank is too high, the oil tank may deform or even break, lacking a certain degree of safety. Therefore, a high-safety turbine blower with automatic oil tank pressure relief and its usage method are proposed to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a high-safety automatic pressure relief turbine blower for oil tanks and its usage method, which improves the safety of oil tank use and solves the problem of inconvenient control of the internal pressure ring of the oil tank in traditional methods.

[0005] (II) Technical Solution To achieve the aforementioned goal of improving the safety of fuel tank use, the present invention provides the following technical solution: a high-safety fuel tank automatic pressure relief turbine blower and its usage method, comprising a first base, a second base being provided at one end of the first base, and a positioning component being provided between the first base and the second base; The motor is mounted on the top outer surface of the second base. A pressure relief pipe is fixedly installed on the top outer surface of the second base on one side of the motor. The bottom end of the pressure relief pipe is connected to the oil tank. A top pipe is fixedly installed on the top end of the pressure relief pipe. A top cover is installed on the top end of the top pipe. Several through holes for pressure relief are opened on the outer surface of the top cover. An adjustment component is installed inside the top pipe. The gearbox is mounted on the top of the first base, and a volute is fixedly installed at the output end of the gearbox. A buffer assembly is provided at the bottom end of the volute.

[0006] Preferably, a base frame is fixedly installed at the bottom of the motor, and a coupling is fixedly connected to the output end of the motor. The output end of the motor is connected to the input end of the gearbox through the coupling, and the gearbox speeds up the motor, driving the turbine impeller to rotate at high speed.

[0007] The volute is equipped with a turbine impeller. An air inlet is provided at the front end of the volute, and an air outlet is provided on one side of the volute. Gas enters the volute from the air inlet flange. The multi-stage impeller accelerates and pressurizes the gas step by step. The volute converts kinetic energy into static pressure, and the gas is discharged from the air outlet. A stable negative pressure is formed at the air inlet, which provides the adsorption force required for vacuum dewatering and shaping of the paper machine.

[0008] Preferably, a gear set is installed inside the gearbox, and a lubricating oil delivery pipe is fixedly connected to one outer surface of the gearbox. The lubricating oil delivery pipe continuously provides lubrication and cooling to the gearbox and bearings to ensure stable operation at high speeds.

[0009] Preferably, the adjusting assembly includes a connecting rod disposed at the center inside the top tube. The top end of the connecting rod is fixedly connected to the outer surface of the bottom end of the top cover, and a base plate is fixedly installed at the bottom end of the connecting rod. A top plate is sleeved on the outer surface of the connecting rod, and a second return spring is sleeved on the outer surface of the connecting rod between the base plate and the top plate. When the pressure in the oil tank is too high during operation, the pressure will push the top cover upward, thereby opening the through holes around the top cover to release pressure. When the top cover moves upward, it will cause the base plate at the bottom end of the connecting rod to press the second return spring upward.

[0010] Preferably, an adjusting ring is fitted on the outer surface of the jacking pipe, and sliders are fixedly installed on both sides of the inner wall of the adjusting ring. Sliding grooves are opened on both sides of the outer surface of the jacking pipe, and one end of the slider is fixedly connected to the outer surface of the top plate. The adjusting ring slides along the sliding groove, and the top plate slides along the connecting rod through the slider, which compresses the second return spring, shortens the length of the second return spring, and thus adjusts the preload of the second return spring.

[0011] Preferably, a pull rod is inserted into the outer surface of the adjusting ring, a first return spring is sleeved on the outer surface of the pull rod, a clamping plate is fixedly installed at one end of the pull rod, a groove is opened on the outer surface of the top tube, and the inner wall of the groove is engaged with the outer surface of the clamping plate. Pulling the pull rod on one side outward causes one side of the clamping plate to disengage from the groove surface, thereby releasing the limiting effect on the adjusting ring.

[0012] Preferably, the buffer assembly includes a support column disposed at the bottom of the volute and a buffer spring sleeved on the outer surface of the support column, and the outer surface of the support column has a telescopic structure. A support plate is fixedly installed at the top of the support column. One end of the volute is supported by the support column and the support plate. The turbine impeller rotates at high speed inside the volute and generates a certain vibration. The generated vibration will compress the buffer spring, thereby providing a certain buffer.

[0013] Preferably, the positioning component includes a positioning block fixedly installed at one end of the first base, a positioning groove matching the positioning block at one end of the second base, fixing pins fixedly installed on both outer surfaces of the second base, and connecting grooves matching one end of the fixing pins on both sides of the positioning block. During assembly, the positioning block at one end of the first base is inserted into the positioning groove of the second base, and then the fixing pins on both sides are screwed in for limiting and fixing.

[0014] A method for using a high-safety automatic pressure relief turbine blower for an oil tank, characterized by the following steps: Step 1: Connect the air inlet of the volute to the vacuum tank of the paper splicer, and connect the air outlet to the heat exchanger; Step 2: Start the motor. The motor output is connected to the gearbox input via a coupling. The gearbox speeds up the turbine impeller and drives it to rotate at high speed. Step 3: Gas enters the volute from the inlet flange. The multi-stage impeller accelerates and pressurizes the gas step by step. The volute converts kinetic energy into static pressure, and the gas is discharged from the outlet. A stable negative pressure is formed at the inlet, providing the adsorption force required for vacuum dehydration and shaping of the paper machine. Step 4: The lubricating oil delivery pipe continuously provides lubrication and cooling to the gearbox and bearings to ensure stable operation at high speeds.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a high-safety automatic pressure relief turbine blower for oil tanks and its usage method, which has the following beneficial effects: The pressure relief pipe is connected to the oil tank. When the air pressure in the oil tank is too high, the air pressure will squeeze the second return spring, push the top cover upward, open the through hole to release pressure, and prevent the air pressure in the oil tank from being too high. After the air pressure is restored, the second return spring will reset the top cover. The length of the second return spring can be adjusted by adjusting the adjustment ring to adjust its preload and control the pressure of pushing the top cover, thereby controlling the air pressure in the oil tank. By setting up a first base and a second base to support the gearbox and motor respectively, when the equipment needs to be moved, the connection between the motor and the gearbox can be disconnected, and then the first base and the second base can be separated to move the gearbox and motor separately, greatly reducing the difficulty of moving. A positioning component is set between the first base and the second base to facilitate precise positioning during assembly. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please see Figure 1-6 The present invention provides the following technical solution: a high-safety automatic pressure relief turbine blower for an oil tank and its usage method, comprising a motor 2 disposed on the top outer surface of a second base 11, a pressure relief pipe 4 fixedly installed on the top outer surface of the second base 11 on one side of the motor 2, the bottom end of the pressure relief pipe 4 being connected to the oil tank, a top pipe 41 fixedly installed on the top end of the pressure relief pipe 4, a top cover 43 installed on the top end of the top pipe 41, a plurality of through holes 431 for pressure relief being opened on the outer surface of the top cover 43, and an adjustment component being provided inside the top pipe 41; In this embodiment, a base frame 21 is fixedly installed at the bottom of the motor 2, and a coupling 3 is fixedly connected to the output end of the motor 2. The output end of the motor 2 is connected to the input end of the gearbox 5 through the coupling 3. The gearbox 5 speeds up the motor and drives the turbine impeller to rotate at high speed. The turbine impeller is installed inside the volute 6. An air inlet 61 is provided at the front end of the volute 6, and an air outlet 62 is provided on one side of the volute 6. Gas enters the volute 6 from the flange of the air inlet 61. The multi-stage impeller accelerates and pressurizes the gas step by step. The volute 6 converts kinetic energy into static pressure, and the gas is discharged from the air outlet 62. A stable negative pressure is formed at the air inlet 61, which provides the adsorption force required for vacuum dewatering and shaping of the paper machine.

[0020] The gearbox 5 is equipped with a gear set inside, and a lubricating oil delivery pipe 51 is fixedly connected to one side of the outer surface of the gearbox 5. The lubricating oil delivery pipe 51 continuously provides lubrication and cooling to the gearbox 5 and the bearings to ensure stable operation at high speeds.

[0021] In this embodiment, the adjusting component includes a connecting rod 45 disposed at the center inside the top tube 41. The top end of the connecting rod 45 is fixedly connected to the outer surface of the bottom end of the top cover 43. A base plate 451 is fixedly installed at the bottom end of the connecting rod 45. A top plate 46 is sleeved on the outer surface of the connecting rod 45. A second return spring 452 is sleeved on the outer surface of the connecting rod 45 between the base plate 451 and the top plate 46. When the pressure in the oil tank is too high during operation, the pressure will push the top cover 43 upward, thereby opening the through holes 431 around the top cover 43 to release pressure. When the top cover 43 moves upward, it will cause the base plate 451 at the bottom end of the connecting rod 45 to press the second return spring 452 upward.

[0022] The outer surface of the jacking pipe 41 is fitted with an adjusting ring 42. The inner walls of the adjusting ring 42 are fixedly installed with sliders 461 on both sides. The outer surfaces of both sides of the jacking pipe 41 are provided with grooves 47. One end of the slider 461 is fixedly connected to the outer surface of the top plate 46. The adjusting ring 42 slides along the groove 47, and the top plate 46 is driven to slide along the connecting rod 45 through the slider 461, which compresses the second return spring 452, shortens the length of the second return spring 452, and thus adjusts the preload of the second return spring 452.

[0023] In this embodiment, it should also be noted that a pull rod 44 is inserted into the outer surface of the adjusting ring 42, a first return spring 441 is sleeved on the outer surface of the pull rod 44, a clamping plate 442 is fixedly installed at one end of the pull rod 44, a clamping groove 48 is opened on the outer surface of the top tube 41, and the inner wall of the clamping groove 48 is engaged with the outer surface of the clamping plate 442. Pulling the pull rod 44 on one side outward will disengage one side of the clamping plate 442 from the surface of the clamping groove 48, thereby releasing the limitation on the adjusting ring 42.

[0024] The working principle of this embodiment is as follows: When in use, start motor 2. The output end of motor 2 is connected to the input end of gearbox 5 through coupling 3. The gearbox 5 speeds up the turbine impeller, causing it to rotate at high speed. Gas enters the volute 6 from the inlet flange 61. The multi-stage impeller accelerates and pressurizes the gas step by step. The volute 6 converts kinetic energy into static pressure, and the gas is discharged from the outlet 62. A stable negative pressure is formed at the inlet 61, providing the suction force required for vacuum dehydration and shaping of the paper machine. The lubricating oil delivery pipe 51 continuously provides lubrication and cooling to the gearbox 5 and bearings, ensuring stable operation at high speeds. When the pressure in the oil tank is too high during operation, the pressure will push the top cover 43 upward, thereby opening the through holes 431 around the top cover 43 to release pressure. As the top cover 43 moves upward, it will cause the bottom plate 451 at the bottom of the connecting rod 45 to press the second return spring 452 upward. When it is necessary to adjust the preload of the second return spring 452, the pull rod 44 on one side can be pulled outward to disengage one side of the clamping plate 442 from the surface of the clamping groove 48, thereby releasing the limiting effect on the adjusting ring 42. Then, the adjusting ring 42 slides along the slide groove 47, and the top plate 46 slides along the connecting rod 45 through the slider 461, which compresses the second return spring 452 and shortens its length, thereby adjusting the preload of the second return spring 452 and adjusting the pressure of pushing the top cover 43. After the position of the adjusting ring 42 is adjusted, the pull rod 44 is released, and the first return spring 441 will push the clamping plate 442 inward to reset, so that the surface of the clamping plate 442 engages with the inner wall of the clamping groove 48 for limiting.

[0025] Example 2 Please see Figure 7-8The present invention provides the following technical solution: a high-safety automatic pressure relief turbine blower for oil tank and its usage method, including a first base 1, a second base 11 is provided at one end of the first base 1, and a positioning component is provided between the first base 1 and the second base 11. In this embodiment, the positioning component includes a positioning block 12 fixedly installed at one end of the first base 1, a positioning groove 13 matching the positioning block 12 is opened at one end of the second base 11, and fixing pins 14 are fixedly installed on the outer surfaces of both sides of the second base 11. The positioning block 12 has connecting grooves matching one end of the fixing pins 14 on both sides. During assembly, the positioning block 12 at one end of the first base 1 is inserted into the positioning groove 13 of the second base 11, and then the fixing pins 14 on both sides are screwed in for limiting and fixing. In this embodiment, the gearbox 5 is installed on the top of the first base 1, and a volute 6 is fixedly installed on the output end of the gearbox 5. A buffer assembly is provided at the bottom end of the volute 6.

[0026] The buffer assembly includes a support column 63 disposed at the bottom of the volute 6 and a buffer spring 64 sleeved on the outer surface of the support column 63. The outer surface of the support column 63 is telescopic. A support plate 65 is fixedly installed at the top of the support column 63. One end of the volute 6 is supported by the support column 63 and the support plate 65. The turbine impeller rotates at high speed inside the volute 6, which will generate a certain vibration. The generated vibration will compress the buffer spring 64, thereby providing a certain degree of buffering.

[0027] The working principle of this embodiment is as follows: During use, one end of the volute 6 is supported by the support column 63 and the support plate 65, and the turbine impeller rotates at high speed inside the volute 6, which will generate a certain vibration. The vibration will compress the buffer spring 64, thereby buffering and reducing the transmission of vibration. When the equipment needs to be moved, use a tool to rotate the fixing pin 14 so that one end of the fixing pin 14 is disengaged from one end of the positioning block 12, thereby releasing the limit between the first base 1 and the second base 11 and disconnecting the motor 2 from the gearbox 5. Then, the first base 1 and the second base 11 are separated, and the gearbox 5 and the motor 2 are moved separately, greatly reducing the difficulty of moving. When assembling, insert the positioning block 12 at one end of the first base 1 into the positioning groove 13 of the second base 11, and then screw in the fixing pins 14 on both sides to limit and fix them.
