Description
Technical Field
[0001] The utility model belongs to the technical field of anti-corrosion wooden pole processing, and particularly relates to a vacuum treatment device for anti-corrosion oil wooden poles. Background Technique
[0002] Due to its anti-corrosion, waterproof and durable characteristics, anti-corrosion oil wooden poles have become an ideal choice for outdoor billboards, road signal lights, communication or power transmission line support structures. The wooden poles can form a protective film on the surface of the workpiece through methods such as dipping, brushing or spraying, playing roles such as lubrication and rust prevention.
[0003] Traditional oil wooden poles are generally oiled by vacuum treatment. First, the surface of the wooden pole is cleaned to remove surface dirt and moisture so that the preservative can penetrate better. After the wooden pole is cleaned, it is placed in a vacuum container, and the air in the container is pumped out to form a negative pressure environment, and the preservative is injected, and the pressure is maintained for a period of time to facilitate the full combination of the preservative and the wooden pole.
[0004] During the vacuum treatment process, multiple wooden poles are inserted side by side into the tank body. First, the vacuum is pumped and then the preservative is injected. These wooden poles are closely attached to each other in the stacked state, and the contact areas block each other, hindering the immersion of the oil liquid, resulting in oil immersion blank zones on the surface of the wooden poles. Moreover, it is not convenient to separate each wooden pole in the tank body, which is not conducive to the all-round vacuum oil immersion treatment of the wooden poles. Content of the Utility Model
[0005] The purpose of the utility model is to provide a vacuum treatment device for anti-corrosion oil wooden poles, which can separate each wooden pole by using an internal skeleton inside the anti-corrosion oil, and use multi-point support to reduce the contact area with the wooden pole, and promote the all-round vacuum oil immersion treatment of the wooden pole.
[0006] The technical solution adopted by the utility model is specifically as follows:
[0007] An anti-corrosion oil-treated wooden pole vacuum treatment device includes a tank body, a gas storage tank, and a vacuum pump that are connected in sequence from right to left. The tank body has a structure with an open door at one end. Inside the tank body, there are multiple flange rings spaced along the axial direction. The flange rings are provided with multiple unit holes spaced apart and facing the open door of the tank body. A plurality of steel rods penetrating through the flange rings are fixedly spaced on the inner wall of the tank body. The steel rods are all horizontally staggered from the unit holes, and the central axes of the steel rods are all parallel to the central axis of the tank body. The lower surface of the tank body is connected with an oil inlet valve. First, the air in the gas storage tank is preferentially sucked to reach a certain negative pressure condition, and then the air inside the tank body is gradually sucked away. After the internal pressure is reduced to the specified range, an oil supply pump can be selected to input anti-corrosion oil into the tank body. Using the negative pressure condition, the anti-corrosion oil is distributed on the surface of the wooden pole. At this time, the inner skeleton composed of the flange rings and the steel rods is used to support the wooden pole inside the anti-corrosion oil, using multi-point support to reduce the contact area with the wooden pole and separate each wooden pole, promoting the all-round vacuum oil immersion treatment of the wooden pole. After maintaining the pressure for a certain period of time, the anti-corrosion oil fully infiltrates the wooden pole. Finally, the remaining anti-corrosion oil is discharged, the sealed door is opened, and the anti-corrosion oil-treated wooden poles are taken out one by one.
[0008] As a preferred solution, two first thimbles are fixedly spaced on the upper walls of the unit holes, and the lower ends of the first thimbles all point to the middle of the unit holes. When the wooden pole floats in the anti-corrosion oil and approaches the upper wall of the unit hole, each first thimble supports the wooden pole downward, and multi-point support can also be carried out to prevent the wooden poles from piling up together, and further reduce the support area, effectively controlling the oil immersion blank zone that appears on the surface of the wooden pole, which has a positive significance for the process change of the vacuum treatment of the wooden pole.
[0009] As a preferred solution, the lower edges of the flange rings are detachably connected with support seats, and the lower surfaces of the support seats are fixedly connected to the lower wall of the tank body. The lower surfaces of the support seats are fixedly connected to the lower wall of the tank body. The flange rings are supported by the support seats and suspended, leaving an installation space for each flange ring inside the tank body.
[0010] As a preferred solution, a plurality of second thimbles are fixedly spaced at positions inside the tank body far from the open door. The second thimbles are all horizontally facing the unit holes. When the wooden pole approaches the bottom of the tank body, it is limited by the second thimbles to prevent the end of the wooden pole from sticking to the inner wall of the tank body and being blocked.
[0011] As a preferred solution, a reinforcing plate is welded at a position on the outer surface of the tank body far from the open door. The reinforcing plate is horizontally facing the second thimble. When the second thimble bears the load, the reinforcing plate supports the root of the second thimble to enhance the structural strength and can stably support the wooden pole.
[0012] As a preferred solution, the lower surface of the tank body is also connected with an oil drain valve. After the oil immersion is completed, the oil drain valve is opened to relieve the pressure and discharge the remaining anti-corrosion oil, realizing the safe and standardized operation of taking out the wooden pole.
[0013] As a preferred solution, an oil drain pump is provided outside the tank body. The oil inlet of the oil drain pump is connected to the lower port of the oil drain valve. After the oil drain valve is opened, the oil drain pump can be started to suck the remaining anticorrosive oil inside the tank body and temporarily store it in the oil tank, shortening the oil drain time.
[0014] The technical effects achieved by the present utility model are as follows:
[0015] The present utility model preferentially sucks the air inside the gas storage tank to reach a certain negative pressure condition, and then gradually sucks away the air inside the tank body. After reducing the internal pressure to the specified range, an oil supply pump can be selected to input anticorrosive oil into the tank body. The anticorrosive oil is distributed on the surface of the wooden poles by using the negative pressure condition. At this time, the inner skeleton composed of the flange ring and the steel rod is used to support the wooden poles inside the anticorrosive oil, using multi-point support to reduce the contact area with the wooden poles and separate each wooden pole, promoting the all-round vacuum oil immersion treatment of the wooden poles. After maintaining the pressure for a certain period of time, the anticorrosive oil fully infiltrates the wooden poles. Finally, the remaining anticorrosive oil is drained, the sealing door is opened, and the anticorrosive oil wooden poles are taken out one by one.
[0016] When the wooden poles of the present utility model are immersed in the anticorrosive oil, they will float. When approaching the upper wall of the unit hole, each first thimble supports the wooden poles downward, which can also perform multi-point support, avoiding the accumulation of wooden poles together, and further reducing the support area, effectively controlling the oil immersion blank zone on the surface of the wooden poles, which is of positive significance for the process change of the vacuum treatment of the wooden poles.

[0023] In order to make the purpose and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.
[0024] As Figures 1 - 4 shown, an anti-corrosion oil-treated wooden pole vacuum treatment device, the entire device is controlled by an industrial computer, and includes a tank body 1, a gas storage tank 2 and a vacuum pump 3 that are connected in sequence from right to left. The tank body 1 has a structure with one end open. Inside the tank body 1, there are a plurality of flange rings 4 spaced along the axial direction. The number of flange rings 4 is at least two, so as to stably support the wooden pole to be suspended. In this embodiment, preferably 4 flange rings 4 are used, which are suitable for wooden poles with a larger span. A plurality of unit holes 5 facing the opening of the tank body 1 are spaced on the flange ring 4. The number of unit holes 5 can be 10 to 36. First, when the number is 10, it is convenient to maintain the structural strength of the flange ring 4. Second, when the number is 36, on the premise of sacrificing part of the structural strength, as many wooden poles as possible can be placed. In this embodiment, preferably 17 unit holes 5 are used, which can be evenly distributed. A plurality of steel rods 6 penetrating through the flange rings 4 are fixedly spaced on the inner wall of the tank body 1. The steel rods 6 are all horizontally staggered with the unit holes 5, and the central axes of the steel rods 6 are all parallel to the central axis of the tank body 1. An oil inlet valve 7 is connected to the lower surface of the tank body 1. The oil inlet valve 7 can select an electric magnetic valve of the DFD model. Both the vacuum pump 3 and the oil inlet valve 7 are signal-connected to the industrial computer. The oil inlet of the oil inlet valve 7 is connected to an oil supply pump. This technical solution is an existing technology and is not shown in the figure.
[0025] In the preparation stage, the wooden poles are cleaned and dried to remove dirt and moisture on the surface, so that the preservative can penetrate better. Secondly, a sufficient amount of anti-corrosion oil is poured into the storage oil tank as the oil source and is connected to the oil supply pump.
[0026] In the feeding stage, the sealing door of the tank body 1 is opened, and the above-mentioned wooden poles are horizontally placed into the tank body 1 one by one. The wooden poles pass through the unit holes 5 along the axial direction, and each wooden pole is supported by the flange rings 4 and the steel rods 6, thereby separating the wooden poles.
[0027] In the vacuum treatment stage, the sealing door and the oil inlet valve 7 are closed, the vacuum pump 3 is started, and the air in the gas storage tank 2 is preferentially sucked to reach a certain negative pressure condition. Then, the gas valve between the tank body 1 and the gas storage tank 2 is opened, and the air inside the tank body 1 is gradually sucked away. After the internal pressure is reduced to the specified range, the gas valve is closed and the oil inlet valve 7 is opened. The oil supply pump can be selected to input anti-corrosion oil into the tank body 1, and the anti-corrosion oil is distributed on the surface of the wooden poles by using the negative pressure condition. At this time, the inner framework composed of the flange rings 4 and the steel rods 6 is used to support the wooden poles inside the anti-corrosion oil, and the contact area with the wooden poles is reduced by using multi-point support, and each wooden pole is separated, promoting the all-round vacuum oil immersion treatment of the wooden poles. After maintaining the pressure for a certain time, the anti-corrosion oil fully infiltrates the wooden poles. Finally, the remaining anti-corrosion oil is discharged, the sealing door is opened, and the anti-corrosion oil-treated wooden poles are taken out one by one.
[0028] Among them, the edges of the unit holes 5 all have rounded corners, and the arc surfaces can be used to guide the inserted wooden rods upwards, avoiding jamming the wooden rods and facilitating the smooth insertion of each wooden rod.
[0029] Refer to Appendices Figure 1 、 Figure 3 and Figure 4 。On the upper walls of the unit holes 5, two first ejector pins 8 are fixedly arranged at intervals, and the lower ends of the first ejector pins 8 all point to the middle of the unit holes 5. When the wooden rods are immersed in the antiseptic oil, they will float upwards. When approaching the upper walls of the unit holes 5, the wooden rods are supported downward by the respective first ejector pins 8, and multi-point support can also be carried out, avoiding the accumulation of wooden rods together, and further reducing the support area, effectively controlling the oil immersion blank zone on the surface of the wooden rods, which has a positive significance for the process change of the vacuum treatment of the wooden rods.
[0030] Refer to Appendices Figure 1 、 Figure 3 and Figure 4 。On the lower edges of the flange rings 4, support seats 9 are detachably connected. The detachable function can be realized by using the cooperation of bolts and nuts or the method of tightening with screws. In this embodiment, it is preferably to use the cooperation of bolts and nuts to fix the connection between the flange ring 4 and the support seat 9, which can bear a large load. The lower surfaces of the support seats 9 are fixedly connected to the lower wall of the tank body 1, and the flange rings 4 are supported by the support seats 9 to be suspended, leaving an installation space for each flange ring 4 inside the tank body 1.
[0031] Refer to Appendices Figure 1 and Figure 3 。Inside the tank body 1, a plurality of second ejector pins 10 are fixedly arranged at intervals at positions far from the door opening. The second ejector pins 10 are all horizontally facing the unit holes 5. When the wooden rods approach the bottom of the tank body 1, they are limited by the second ejector pins 10 to prevent the ends of the wooden rods from sticking to the inner wall of the tank body 1 and being blocked.
[0032] Refer to Appendices Figure 1 and Figure 2 。On the outer surface of the tank body 1, at a position far from the door opening, a reinforcing plate 11 is welded. The reinforcing plate 11 is horizontally facing the second ejector pins 10. When the second ejector pins 10 bear the load, the reinforcing plate 11 supports the roots of the second ejector pins 10 to enhance the structural strength and can stably support the wooden rods.
[0033] Refer to Appendices Figure 1 and Figure 2 。On the lower surface of the tank body 1, an oil drain valve 12 is also connected. The oil drain valve 12 can select an electric solenoid valve of the DFD model. The oil drain valve 12 is signal-connected to an industrial computer. After the oil immersion is completed, the oil drain valve 12 is opened to release the pressure and discharge the remaining antiseptic oil, realizing the safe and standardized operation of taking out the wooden rods.
[0034] Refer to Appendices Figure 1 and Figure 2, an oil drain pump 13 is provided outside the tank body 1. The oil drain pump 13 is signal-connected to an industrial computer. The oil inlet of the oil drain pump 13 is communicated with the lower port of the oil drain valve 12. After the oil drain valve 12 is opened, the oil drain pump 13 can be started to suck the remaining anticorrosive oil inside the tank body 1 and temporarily store it in the oil tank, so as to shorten the oil drainage time.
[0035] The working principle of the present utility model is as follows: during operation, the above-mentioned wooden rods are horizontally placed into the tank body 1 one by one. The wooden rods axially pass through the unit holes 5, and each wooden rod is supported by the flange ring 4 and the steel rod 6, thereby separating the wooden rods.
[0036] After closing the sealing door, start the vacuum pump 3. First, suck the air in the gas storage tank 2 to reach a certain negative pressure condition, then open the gas valve between the tank body 1 and the gas storage tank 2, and gradually suck out the air inside the tank body 1. After reducing the internal pressure to the specified range, close the gas valve and open the oil inlet valve 7. A supply oil pump can be selected to input anticorrosive oil into the tank body 1, and use the negative pressure condition to distribute the anticorrosive oil to the surface of the wooden rods. At this time, the inner skeleton composed of the flange ring 4 and the steel rod 6 is used to support the wooden rods inside the anticorrosive oil, use multi-point support to reduce the contact area with the wooden rods, and separate each wooden rod, so as to promote the all-round vacuum oil immersion treatment of the wooden rods. After maintaining the pressure for a certain period of time, the anticorrosive oil fully infiltrates the wooden rods. Finally, drain the remaining anticorrosive oil, open the sealing door, and take out the anticorrosive oil wooden rods one by one.
