Description

Technical Field

[0001] The invention relates to the technical field of power oil recovery, in particular to a separation device for recovering retired power oil. Background Art

[0002] The recycling of power oil, especially transformer oil, is an important task that is both environmentally friendly and resource-saving. Transformer oil will gradually age during long-term use and may contain harmful chemical substances such as diphenyl and polycyclic aromatic hydrocarbons, as well as fine particle impurities. If these substances are directly discharged into the environment without treatment, they will pose a potential threat to the environment and human health. Therefore, by recycling and treating these waste oils, the risk of environmental pollution can be effectively reduced.

[0003] When recycling power recovery oil, it often needs to go through multiple separation processes, including chemical separation process and physical separation process. The chemical separation process converts harmful substances in transformer oil into harmless substances through chemical reactions, while the physical separation process uses physical adsorbents to adsorb and separate impurities and harmful substances in transformer oil. The commonly used physical separation process is to use filters, which can filter out solid impurities contained in power recovery oil.

[0004] After long-term use, the physical and chemical properties of existing power recovery oil will gradually change due to factors such as oxidation, aging and pollution, resulting in poor fluidity and increased viscosity of the oil. When the existing filter filters the power recovery oil, the power recovery oil passes through one end of the filter and is filtered and transported to the other end. It often relies on its own flow or gravity as the power to pass through the filter mesh of the filter, and the filtration speed is slow. Summary of the invention

DETAILED DESCRIPTION

[0037] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0038] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, in an embodiment of the present invention, a separation device for recovering retired power oil includes an oil storage cylinder 1, a separation component 2, a pressure sensor 5, a locking component 8, a locking controller 4 and an oil collection cylinder 3;

[0039] The oil storage cylinder 1 is used to store the oil to be separated; the separation component 2 is installed at the bottom of the oil storage cylinder 1, and includes multiple groups of separation cylinders 201. The upper ends of the multiple groups of separation cylinders 201 are correspondingly connected to the drainage ports opened at the bottom of the oil storage cylinder 1. A group of separation nets 203 are correspondingly disassembled and installed at the bottom of each group of separation cylinders 201. A group of pressurized plugs 204 are slidably installed in the cylinder body of the separation cylinder 201 located on the upper side of the separation net 203. The pressurized plugs 204 are elastically installed on the separation cylinder through an elastic component. 201, the elastic component is used to elastically support the pressurized plug 204 to move toward the side close to the separation net 203, a channel for oil to pass through is provided in the pressurized plug 204, and a spherical valve body 209 is rotatably installed in the channel, and a group of swing plates 210 are rotatably installed on both sides of the pressurized plug 204, and the mounting shafts 2091 at both ends of the spherical valve body 209 are rotatably connected to one end of the corresponding side swing plate 210, and a rotary column 2101 is rotatably installed on the other end of the swing plate 210. The rotary column 2101 is slidably connected in the limiting ring groove 205 opened on the side wall of the separation cylinder 201. A group of transmission rods 7 are fixedly installed on the side of the multiple groups of pressurized plugs 204 away from the separation net 203. The upper ends of the multiple groups of transmission rods 7 are transmission-connected with the lifting plate 6 in the oil storage cylinder 1, and the lifting plate 6 is driven to reciprocate and rise and fall through the driving member; the pressure sensor is installed on the side of the spherical valve body 209 pressing down the oil, and is used to transmit the pressure data of the spherical valve body 209 pressing down to the locking controller 4; the multiple groups of locking components 8 are fixedly installed on the lifting plate 6, which are used to transmission-connect the corresponding transmission rod 7 with the lifting plate 6; the locking controller 4 is used to receive the pressure data of the multiple groups of pressure sensors, and when the pressure value of the pressure sensor on the spherical valve body 209 is greater than the preset pressure standard value, the corresponding locking component 8 is controlled to loosen the transmission rod 7 at the end of the pressurized plug 204 installed with the spherical valve body 209; the oil collecting cylinder 3 is installed at the bottom of the separation component 2, and is used to recover the oil passing through the separation component 2;

[0040] Specifically, in the present invention, by setting up multiple groups of separation cylinders 201, each group of separation cylinders 201 can independently realize the separation and filtration operation of oil. When the separation net 203 in one group of separation cylinders 201 is seriously clogged, causing the spherical valve body 209 in this separation cylinder 201 to squeeze the oil during the downward movement of the pressurized plug 204. When the pressure value of the pressure sensor generated by squeezing the oil is greater than the preset pressure standard value, the corresponding locking component 8 is controlled by a fixed controller to loosen the transmission rod 7 installed with the end of the spherical pressurized plug 204, so that the transmission rod 7 is out of contact with the lifting plate 6, and the pressurized plug 204 moves downward under the action of the elastic component, squeezes the oil and seals the upper end of the separation net 203. At this time, the operator can separate and repair the separation net 203 at the bottom of the separation cylinder 201, while other separation cylinders 201 can continue to maintain the separation operation to avoid interruption of oil separation.

[0041] like Figure 4 As shown, in the embodiment of the present invention, the elastic component includes two groups of guide rods 206 and two groups of support springs 207. The two groups of guide rods 206 are respectively installed on both sides of the pressurized plug 204. The two groups of guide rods 206 are slidably installed in the guide cavities opened on the inner walls of the two sides of the separation cylinder 201. The two groups of support springs 207 are fixedly installed in the corresponding guide cavities. The movable ends of the support springs 207 are fixedly connected to the ends of the corresponding guide rods 206. In the present invention, the two groups of guide rods 206 are moved by the pressurized plug 204, and the two groups of support springs 207 are correspondingly driven to deform. During the deformation process, the support springs 207 provide elastic force to drive the pressurized plug 204 to move toward the separation net 203. When the locking assembly 8 unlocks the transmission rod 7, this elastic force can drive the pressurized plug 204 to move downward to squeeze and separate the oil.

[0042] Of course, when actually setting up the elastic component, the arrangement of the support spring 207 in the present invention may be modified. Under the requirement of maintaining the elastic reset capability, the present invention does not impose rigid requirements on the structure of the elastic component.

[0043] like Figure 4 , Figure 5 as well as Figure 6 As shown, in the embodiment of the present invention, the end of the pressurizing plug 204 is provided with a fan-shaped groove 2041 for the swing plate 210 to rotate, and the swing angle of the fan-shaped groove 2041 is 90°. In the present invention, when the pressurizing plug 204 is lifted and moved to drive the swing plate 210 to rotate, the fan-shaped groove 2041 limits the extreme positions of the swing plate 210 when it moves to both sides. In the present invention, the designed spherical valve body 209 can seal or connect the oil delivery channel in the pressurizing plug 204 when it is rotated and switched at 90°.

[0044] Further, the limiting ring groove 205 includes two groups of straight grooves 2051, an inclined groove 2052 and a guide block 208. The two groups of straight grooves 2051 are vertically and parallelly opened on the inner wall of the separation cylinder 201, and the two groups of straight grooves 2051 have a height difference in the vertical direction. The two groups of inclined grooves 2052 are arranged in parallel, and the top and bottom of the two groups of straight grooves 2051 are connected respectively, and the angle between the lower inclined groove 2052 and the clamp at the lowest position swing plate 210 is greater than 90°. The two groups of guide blocks 208 are slidably connected to the top of the high straight groove 2051 and the bottom of the low straight groove 2051, and are elastically connected to the inner wall of the separation cylinder 201 through the connecting spring 211. The two groups of guide blocks 208 are used to guide the rotating column 2101 to slide to the corresponding inclined groove 2052 when the rotating column 2101 slides to the end of the corresponding straight groove 2051 and moves in the opposite direction;

[0045] In the present invention, by providing a connected limiting annular groove 205, when the pressurizing plug 204 moves up and down reciprocatingly in the vertical direction, the spherical valve body 209 is driven to rotate to a channel connected state during the upward sliding of the pressurizing plug 204 by the rotating column 2101, and to rotate to a channel closed state during the downward sliding of the pressurizing plug 204. Specifically:

[0046] In the present invention, when the pressurized plug 204 slides upward from the bottom to the highest point, the rotating column 2101 rotating at one end of the swing plate 210 slides from the bottom of the bottom inclined groove 2052 to the top of the high-position straight groove 2051, wherein the rotating column 2101 slides from the bottom of the bottom inclined groove 2052 to the bottom of the high-position straight groove 2051 (the left straight groove 2051), at this time, the ball valve body 209 rotates from the channel closed state to the channel open state, and when moving upward along the high-position straight groove 2051 (the left straight groove 2051), the channel in the ball valve body 209 remains open, so that the oil on the upper part of the filter cartridge can enter the bottom of the pressurized plug 204 through the channel. It should be noted that when the rotating column 2101 slides to the top of the high-position straight groove 2051 (the left straight groove 2051), it is located in the high-position straight groove. After the guide block 208 at the top of 2051 (left straight groove 2051) is squeezed in by the rotary column 2101, it is supported and extended by the connecting spring 211 to guide and support the bottom of the rotary column 2101, and when the pressurizing plug 204 slides downward from the highest part to the lowest part, the rotary column 2101 is guided to the high inclined groove 2052 and slides downward, wherein the rotary column 2101 slides from the top of the top inclined groove 2052 to the top of the low straight groove 2051 (right straight groove 2051), at this time, the spherical valve body 209 rotates from the channel open state to the channel closed state, and when it moves downward along the low straight groove 2051 (right straight groove 2051), the channel in the spherical valve body 209 remains in a closed state, so that the pressurizing plug 204 can squeeze the oil in the lower part of the filter cartridge to pass through the separation net 203 for separation operation.

[0047] like Figure 4 and Figure 5 As shown, in the embodiment of the present invention, the driving member is a driving cylinder 9, which is fixedly installed at the bottom of the oil storage cylinder 1, and its driving shaft passes through the connecting port of the bottom plate of the oil storage cylinder 1, and is fixedly connected to the center of the lifting plate 6. The present invention drives the lifting plate 6 to rise and fall through the reciprocating extension and contraction of the driving cylinder 9, and the multiple groups of transmission rods 7 connected to the peripheral side of the lifting plate 6 drive the correspondingly connected pressurized plugs 204 to rise and fall reciprocally;

[0048] Of course, in actual design, the driving cylinder 9 for providing reciprocating lifting power can also be replaced by other components with this capability, such as a gear rack reciprocating transmission structure, etc.

[0049] like Figure 2 and Figure 3 As shown, in the embodiment of the present invention, the locking assembly 8 includes a fixed seat 801, a telescopic rod 802 and a locking plug 803. The fixed seat 801 is fixedly installed on the lifting plate 6, and is provided with a placement cavity therein, and a connecting hole is opened on the fixed seat for the transmission rod 7 to pass through. The telescopic rod 802 is fixedly installed in the placement cavity, and its telescopic end faces the connecting hole of the fixed seat 801. The locking plug 803 is fixedly installed at the telescopic end of the telescopic rod 802. An opening is provided on the inner wall of the connecting hole for the locking plug 803 to slide out, and a locking hole is provided on the transmission rod 7 for the locking plug 803 to be inserted into a limited position.

[0050] In the present invention, when the locking controller 4 receives a pressure value greater than a preset pressure standard value from the pressure sensor on the spherical valve body 209, it can control the telescopic rod 802 in the corresponding locking assembly 8 to contract, driving the locking plug 803 at its telescopic end to disengage from the transmission rod 7, loosening the transmission rod 7 at the end of the pressurized plug 204 on which the spherical valve body 209 is installed, and the pressurized plug 204 is pulled downward by the elastic force of multiple groups of supporting springs 207 to move back to the original position, and the separation cylinder 201 is in a state where it cannot be separated. The locking controller 4 can prompt the operator by means of an alarm, and the operator can clean or replace the separation net 203 through the inspection port 202 at the bottom of the separation cylinder 201, and when the maintenance of the separation net 203 is completed, a control signal is sent to the locking controller 4, and the locking controller 4 controls the driving cylinder 9 to drive the lifting plate 6 to move to the lowest position, and controls the locking assembly 8 and the corresponding transmission rod 7 to reset and lock.

[0051] In summary, the present invention provides multiple sets of separation cylinders 201 in the separation assembly 2, and slides a pressurized plug 204 with a spherical valve body 209 in each set of separation cylinders 201, specifically when realizing the physical separation operation of power recovery oil;

[0052] 1. A set of swing plates 210 are rotatably installed on both sides of the pressurizing plug 204, and the ends of the swing plates 210 are slidably connected with the limiting ring groove 205 on the inner wall of the separation cylinder 201 through the rotating column 2101, so that when the pressurizing plug 204 slides upward from the bottom to the highest point, the rotating column 2101 rotating at one end of the swing plate 210 slides from the bottom of the bottom inclined groove 2052 to the top of the high-position straight groove 2051, and at this time, the spherical valve body 209 rotates from the channel closed state to the channel open state, so that the filter cylinder The oil in the upper part can enter the bottom of the pressurizing plug 204 through the channel, and when the pressurizing plug 204 slides downward from the highest part to the lowest part, the rotary column 2101 slides from the top of the top inclined groove 2052 to the top of the low-position straight groove 2051 (the right straight groove 2051), and at this time, the spherical valve body 209 rotates from the channel opening state to the channel closing state, so that the pressurizing plug 204 can squeeze the oil in the lower part of the filter cartridge to pass through the separation net 203 for separation operation, and the separation efficiency of the oil is improved by the extrusion and transportation method;

[0053] 2. By setting up multiple groups of pressure sensors to be fixedly installed on the side of the corresponding spherical valve body 209 to press the oil down, when the locking controller 4 receives a pressure value from the pressure sensor on the spherical valve body 209 that is greater than the preset pressure standard value, it can control the corresponding telescopic rod 802 in the locking assembly 8 to contract, driving the locking plug 803 to disengage from the transmission rod 7, so that the separation cylinder 201 is in a state where it cannot be separated. The locking controller 4 can prompt the operator to perform maintenance operations on the separation net 203 by means of an alarm, while other groups of separation cylinders 201 can still maintain the separation operation state, avoiding interruption of the separation operation and affecting the separation efficiency. The above is a detailed description of the preferred embodiment of the present invention, but the present invention is not limited to the above embodiment. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
