Description

Technical Field

[0001] This utility model belongs to the technical field of wood processing equipment, specifically relating to an oil impregnation processing equipment for the production of anti-corrosion oiled wood poles. Background Technology

[0002] In the production of preservative-treated wooden poles, oil impregnation is a crucial process that determines the final anti-corrosion performance and service life of the poles. Its effectiveness directly impacts the stability of the poles in subsequent outdoor, humid, or corrosive environments. Simultaneously, oil impregnation enhances the wood's impermeability and stability, reduces shrinkage and cracking caused by changes in environmental humidity, further extends the poles' service life, and lowers the frequency of maintenance and replacement, providing long-term, reliable protection for various projects relying on wooden pole support.

[0003] Existing oil-immersion equipment lacks an effective downward pressure mechanism. During the oil-immersion process, the wooden poles tend to float on the surface of the oil due to their own buoyancy, which prevents the wooden poles from being fully immersed in the oil, affecting the uniformity of oil immersion and the anti-corrosion effect. On the other hand, the surface of the wooden poles may be covered with debris before oil immersion. After oil immersion, the debris will mix into the oil. Long-term accumulation will not only contaminate the oil, but may also block the pipeline and reduce the service life.

[0004] Therefore, this application proposes an oil-impregnation processing equipment for the production of anti-corrosion oiled wooden poles to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an oil-impregnation processing equipment for the production of anti-corrosion oiled wooden poles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil-immersion processing equipment for producing anti-corrosion oiled wooden poles, comprising a frame and an oil-immersion tank, wherein the frame is fixedly connected to both sides of the oil-immersion tank, and the top of the oil-immersion tank is provided with symmetrically distributed transverse sliding grooves, wherein a wood-pressing component is slidably connected in the transverse sliding grooves for pressing down the wooden poles in the oil-immersion tank to sink the wooden poles into the oil, and a waste debris filter component for filtering debris in the oil after oil-immersion processing is inserted and connected in the oil-immersion tank;

[0007] The wood pressing assembly includes two connecting sliders that are slidably connected in a transverse groove at the top of the oil immersion tank. The top of the two connecting sliders is fixedly connected to an inverted concave frame. The top of the inverted concave frame has a groove, and the bottom of the groove has a sliding hole. A wood rod measuring mechanism is slidably connected in the sliding hole. The top of the inverted concave frame has symmetrically distributed through holes, and a wood pressing mechanism is slidably connected in each of the two through holes.

[0008] The wood pressing mechanism includes a slide rod slidably connected in the through hole at the top of the inverted concave frame. A wood pressing board is fixedly connected to the bottom of the slide rod. Insertion holes are provided on both sides of the wood pressing board. Insertion rods are inserted into the insertion holes. An extension pressing plate is fixedly connected to one end of the insertion rod.

[0009] Using the above scheme, a designated oil solution is poured into the immersion tank. The wooden poles are then immersed in the oil solution to give them anti-corrosion properties. The wood-pressing assembly slides and adjusts its position via a transverse groove, allowing for pressure on the wooden poles at different locations to prevent them from floating and ensure they are completely submerged in the oil. A waste filter assembly is inserted into the immersion tank to quickly filter debris from the oil, preventing oil contamination and pipe blockage. Together, these components achieve efficient and clean immersion processing. The specific wood-pressing assembly consists of a wood-pressing mechanism, an inverted concave frame, and a wooden pole measuring... The system consists of four parts: positioning mechanism, connecting slider, and inverted concave frame. The inverted concave frame supports the wood pressing mechanism and the wood rod measuring mechanism. The connecting sliders connected to both sides of its bottom slide in the transverse groove to adjust the covering position. The wood pressing mechanism moves up and down by sliding rods that slide in the through hole at the top of the inverted concave frame, which in turn moves the wood pressing board up and down. The wood pressing board applies downward pressure to the wood rod, causing it to sink into the oil. In use, the insert rod and the extension pressure plate can be connected by plugging. Inserting the extension pressure plate can increase the transverse coverage and enhance the downward pressure effect.

[0010] In a preferred embodiment, symmetrically distributed limiting grooves are provided on both sides of the inner wall of the oil immersion tank, rollers are rotatably connected to the front and rear parts of the connecting slider, and limiting bolts are threaded to the side end of the inverted concave frame.

[0011] The above scheme has two limiting grooves on one side and a total of four limiting grooves on both sides. The limiting grooves are used in conjunction with the positioning blocks in the waste filter assembly to provide support. The rollers make the sliding smoother and less strenuous, and the height of the slide bar is limited by the limiting bolts.

[0012] In a preferred embodiment, the insertion rod is inserted into the insertion hole of the pressure board with an interference fit, and the extension pressure board and the pressure board have the same thickness.

[0013] The above solution uses an interference fit between the insertion rod and the insertion hole of the pressure board to prevent the extension pressure plate from loosening and falling off during use, thus ensuring structural stability. The extension pressure plate and the pressure board have the same thickness, which ensures that the pressure on the wooden rod is uniform.

[0014] In a preferred embodiment, the wooden rod positioning mechanism includes a limiting slider that is slidably connected in the sliding hole of the inverted concave frame. A handle is fixedly connected to the top of the limiting slider, and a connecting plate is fixedly connected to the bottom of the limiting slider. An internal thread groove is opened at the end of the connecting plate opposite to the limiting slider. A connecting screw is threadedly connected to the internal thread groove, and a positioning plate is fixedly connected to the bottom of the connecting screw.

[0015] Using the above scheme, the limiting slider slides within the inverted concave frame sliding hole, which can adjust the position of the wooden rod measuring mechanism. The wooden rod measuring mechanism can be moved by holding the handle, thereby detecting the position and immersion depth of the wooden rod by whether the measuring plate is in contact with the wooden rod in the immersion tank, and determining whether the wooden rod can continue to be placed into the immersion tank. The measuring plate is connected by a connecting screw and a threaded groove in the connecting plate. In actual work, different lengths of measuring plates can be selected or whether to install and use the measuring plate can be selected according to the situation.

[0016] In a preferred embodiment, the grip is composed of a base and a handle body, wherein the top of the base is fixedly connected to the handle body, the bottom of the base is fixedly connected to the limiting slider, and the two sides of the base are in contact with the inner wall of the groove at the top of the inverted concave frame.

[0017] With the above solution, the base of the handle fits into the inner wall of the groove at the top of the inverted concave frame, which can limit the shaking of the limiting slider when it slides. The top of the connecting plate fits into the bottom of the inverted concave frame, and the cooperation of the two ensures the stability of the sliding of the limiting slider.

[0018] In a preferred embodiment, the waste filter assembly includes a fine filter plate inserted into and connected to an oil immersion tank. A support plate is fixedly connected to one end of the top of the fine filter plate, and a coarse filter plate is fixedly connected to the other end of the support plate. Positioning blocks are fixedly connected to the four corners on both sides of the coarse filter plate, and positioning rods are fixedly connected to the top of each positioning block.

[0019] Using the above scheme, the coarse filter plate is located above the fine filter plate, and the two work together to achieve dual filtration. The support plate is the supporting structure between the coarse and fine filter plates and maintains a certain distance between them to ensure oil flow. The positioning rod makes it easy for workers to hold and pull out the waste filter assembly for cleaning.

[0020] In a preferred embodiment, the pore size of the coarse filter plate is greater than that of the fine filter plate, and the positioning block is inserted into the limiting groove on the inner wall of the immersion tank.

[0021] Using the above scheme, the coarse filter plate has a larger mesh size than the fine filter plate, ensuring a reasonable filtration sequence of coarse filtration followed by fine filtration. This avoids the fine filter plate from becoming clogged quickly due to directly filtering large particles. The positioning block is inserted into the limiting groove on the inner wall of the immersion tank, which can limit the movement of the waste filter assembly in the immersion tank and ensure stable position during the filtration process.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The wood pressing assembly achieves flexible movement through the cooperation of the connecting slider and the transverse slide. With the pluggable extension pressure plate, it can adapt to wood poles of different lengths and placement positions. This solves the problem of uneven oiling caused by floating wood poles and eliminates the need for frequent replacement of pressing tools, thus improving operational flexibility. The wood pole positioning mechanism can accurately detect the position of the wood pole and the remaining space in the oiling tank through sliding and height adjustment. This can prevent wood poles from being stacked too densely, which would affect penetration, and can monitor the oiling status in real time, reducing the problem of excessive equipment load or substandard oiling caused by blindly adding material.

[0024] The waste filter assembly adopts a two-stage filtration structure with coarse and fine filter plates. The coarse filter plate has a larger pore size than the fine filter plate, which filters out large particles of debris first and then small particles. This effectively avoids rapid clogging of the fine filter plate, extends the service life of the filter assembly, and ensures the cleanliness of the oil, reducing the frequency of oil replacement. The assembly is stably installed by cooperating with the positioning block and the limiting groove of the immersion tank. It is equipped with a positioning rod that is easy to hold, which can prevent the assembly from shaking during filtration and affecting the effect, and can also be quickly pulled out for cleaning.

Detailed Implementation

[0032] Please see Figure 1-6This utility model provides an oil-immersion processing equipment for producing anti-corrosion oiled wooden poles, including a frame 1 and an oil-immersion tank 2. The frame 1 is fixedly connected to both sides of the oil-immersion tank 2. The top of the oil-immersion tank 2 is provided with symmetrically distributed transverse sliding grooves. A wood-pressing component 3 is slidably connected in the transverse sliding grooves to press down the wooden poles in the oil-immersion tank 2 so that the wooden poles sink into the oil. A waste debris filter component 4 is inserted and connected in the oil-immersion tank 2 to filter the debris in the oil after the oil-immersion treatment.

[0033] The wood pressing assembly 3 includes two connecting sliders 34 that are slidably connected in the transverse groove at the top of the oil immersion tank 2. The top of the two connecting sliders 34 is fixedly connected to an inverted concave frame 32. The top of the inverted concave frame 32 is provided with a groove, and the bottom of the groove is provided with a sliding hole. A wood rod measuring mechanism 33 is slidably connected in the sliding hole. The top of the inverted concave frame 32 is provided with symmetrically distributed through holes, and a wood pressing mechanism 31 is slidably connected in each of the two through holes.

[0034] The wood pressing mechanism 31 includes a slide rod 311 that is slidably connected in the through hole at the top of the inverted concave frame 32. A wood pressing board 312 is fixedly connected to the bottom of the slide rod 311. Insertion holes are provided on both sides of the wood pressing board 312. Insertion rods 313 are inserted into the insertion holes. An extension pressing plate 314 is fixedly connected to one end of the insertion rod 313.

[0035] The oil immersion tank 2 is filled with a specified oil solution. The wooden poles are immersed in the oil solution in the immersion tank 2 to give them anti-corrosion properties. The wood pressing assembly 3 is adjusted in position by sliding through a transverse groove, which can press down the wooden poles at different positions to solve the problem of the wooden poles floating and ensure that the wooden poles are completely submerged in the oil solution. The waste filter assembly 4 is inserted into the oil immersion tank 2 to quickly filter the debris in the oil solution, avoiding oil contamination and pipeline blockage. The two work together to achieve efficient and clean oil immersion processing. Specifically, the wood pressing assembly 3 consists of four parts: a wood pressing mechanism 31, an inverted concave frame 32, a wooden pole positioning mechanism 33, and a connecting slider 34. The inverted concave frame 32 supports the wood pressing mechanism 31 and the wood rod measuring mechanism 33, and slides in the transverse groove through the connecting sliders 34 connected to both sides of its bottom, thereby adjusting its covering position. The wood pressing mechanism 31 moves up and down through the sliding rod 311 that slides in the through hole at the top of the inverted concave frame 32, which drives the pressing board 312 to move up and down. The pressing board 312 applies pressure to the wood rod, causing the wood rod to sink into the oil. In use, the insert rod 313 and the extension pressure plate 314 can be connected by plugging. The inserted extension pressure plate 314 can increase the transverse coverage and enhance the pressing effect.

[0036] The inner wall of the oil immersion tank 2 is provided with symmetrically distributed limiting grooves on both sides. The front and rear parts of the connecting slider 34 are rotatably connected with rollers, and the side end of the inverted concave frame 32 is threaded with limiting bolts.

[0037] There are two limiting grooves on one side and a total of four limiting grooves on both sides. The limiting grooves are used in conjunction with the positioning block 43 in the waste filter assembly 4 to provide support. The rollers make the sliding smoother and less strenuous. The height of the slide bar 311 is limited by the limiting bolts.

[0038] The insertion rod 313 is inserted into the insertion hole of the pressure board 312 with an interference fit, and the extension pressure plate 314 and the pressure board 312 have the same thickness;

[0039] The insertion rod 313 and the insertion hole of the pressure board 312 are interference-fitted to prevent the extension pressure plate 314 from loosening and falling off during use, thus ensuring structural stability. The extension pressure plate 314 and the pressure board 312 have the same thickness, which can ensure that the pressure on the wooden rod is uniform.

[0040] The wooden pole positioning mechanism 33 includes a limiting slider 332 that is slidably connected in the sliding hole of the inverted concave frame 32. A handle 331 is fixedly connected to the top of the limiting slider 332, and a connecting plate 333 is fixedly connected to the bottom of the limiting slider 332. An internal thread groove is opened at the end of the connecting plate 333 opposite to the limiting slider 332. A connecting screw 334 is threadedly connected to the internal thread groove, and a positioning plate 335 is fixedly connected to the bottom of the connecting screw 334.

[0041] The limiting slider 332 slides within the sliding hole of the inverted concave frame 32, which can adjust the position of the wooden rod measuring mechanism 33. The wooden rod measuring mechanism 33 can be moved by holding the handle 331. By checking whether the measuring plate 335 is in contact with the wooden rod in the oil immersion tank 2, the position and immersion depth of the wooden rod can be detected, and it can be determined whether the wooden rod can continue to be placed into the oil immersion tank 2. The measuring plate 335 is connected by a connecting screw 334 and a threaded groove in the connecting plate 333. In actual work, different lengths of measuring plates 335 can be selected or the installation and use of measuring plates 335 can be selected according to the situation.

[0042] The grip 331 is composed of a base and a handle body, wherein the top of the base is fixedly connected to the handle body, the bottom of the base is fixedly connected to the limiting slider 332, and the two sides of the base are in contact with the inner wall of the groove at the top of the inverted concave frame 32.

[0043] The base of the handle 331 fits against the inner wall of the groove at the top of the inverted concave frame 32, which can limit the wobbling of the limit slider 332 when it slides. The top of the connecting plate 333 fits against the bottom of the inverted concave frame 32. With the cooperation of the two, the sliding stability of the limit slider 332 is ensured.

[0044] The waste filter assembly 4 includes a fine filter plate 44 inserted into the oil immersion tank 2. One end of a support plate 45 is fixedly connected to the top of the fine filter plate 44, and a coarse filter plate 41 is fixedly connected to the other end of the support plate 45. Positioning blocks 43 are fixedly connected to the four corners on both sides of the coarse filter plate 41, and positioning rods 42 are fixedly connected to the top of each positioning block 43.

[0045] The coarse filter plate 41 is located above the fine filter plate 44. The two work together to achieve dual filtration. The support plate 45 is the support structure between the coarse filter plate 41 and the fine filter plate 44, and maintains a certain distance between them to ensure oil flow. The positioning rod 42 makes it easy for the staff to hold and pull out the waste filter assembly 4 for cleaning.

[0046] The mesh size of the coarse filter plate 41 is larger than that of the fine filter plate 44, and the positioning block 43 is inserted into the limiting groove on the inner wall of the oil immersion tank 2.

[0047] The coarse filter plate 41 has a larger mesh size than the fine filter plate 44, ensuring a reasonable filtration sequence of coarse filtration followed by fine filtration. This prevents the fine filter plate 44 from becoming clogged quickly due to direct filtration of large particles. The positioning block 43 is inserted into the limiting groove on the inner wall of the oil immersion tank 2, which can limit the shaking of the waste filter assembly 4 in the oil immersion tank 2 and ensure stable position during the filtration process.

[0048] When using the product, first slowly add anti-corrosion oil to the immersion tank 2 until the oil level reaches the highest level marked on the inner wall of the immersion tank 2. Then, neatly place the wooden rods to be immersed in the immersion tank 2, ensuring that the length of the wooden rods is aligned with the length of the immersion tank 2 to avoid overcrowding. After the wooden rods are placed in the immersion tank 2, adjust the position of the wood pressing assembly 3 and push the inverted concave frame 32. The connecting slider 34 slides along the transverse groove to align the wood pressing mechanism 31 with the wooden rod. Hold the top of the slide rods 311 of the two wood pressing mechanisms 31 with both hands and slowly press down on the slide rods 311. This will cause the wood pressing board 312 and the extension pressing plate 314 to move down until the bottom of the pressing plate is completely in contact with the top of the wooden rod, thus completely pressing the wooden rod into the oil. Then, tighten the side limit bolts of the inverted concave frame 32 so that its end abuts against the outer surface of the slide rod 311 to fix the position of the wood pressing mechanism 31.

[0049] Then, grasp the handle 331 of the wooden rod measuring mechanism 33 and push the limiting slider 332 to slide along the sliding hole at the top of the inverted concave frame 32, so that the measuring plate 335 moves in the oil in the immersion tank 2. If the measuring plate 335 does not directly contact the wooden rod, it means that there is still space in the immersion tank 2 and the wooden rod can continue to be placed. If the sliding is not smooth, it means that the maximum capacity has been reached and the wooden rod should not be placed anymore. If detailed measurement is required, after the wooden rod measuring mechanism 33 slides to a suitable position, rotate the connecting screw 334 to adjust the height of the measuring plate 335 so that the measuring plate 335 moves downward and stops after the bottom of the measuring plate 335 contacts the top of the wooden rod, thus completing the specific measurement at this position. After the immersion time is reached, drive the sliding rod 311 to slide upward in the through hole of the inverted concave frame 32 to release the limitation on the wooden rod. Then slide the pressing wood assembly 3 to one side through the transverse sliding groove. Then take out the wooden rod after the oil treatment. After the wooden rod is taken out, repeat the above operation for the next round of processing.

[0050] When the oil in the immersion tank 2 needs to be replaced, first drain the oil through the drain port located at the bottom of the immersion tank 2. During the oil draining process, the debris falling from the wooden rods is filtered by the coarse filter plate 41 and the fine filter plate 44. After all the oil has been drained, close the drain port again and lift the debris filter assembly 4 upwards using the four positioning rods 42 to remove the coarse filter plate 41, support plate 45, and fine filter plate 44 from the immersion tank 2. Then, the debris on the coarse filter plate 41 and fine filter plate 44 can be carefully cleaned. Before pulling them out, the measuring plate 335 needs to be removed and the sliding rod 311 should be slid to the highest position to avoid affecting the removal of the debris filter assembly 4. After the filter assembly 4 is completely pulled out of the oil immersion tank 2, the waste filter assembly 4 is taken out from the opposite side of the wood pressing assembly 3. The positioning rod 42 and the wood pressing mechanism 31 are staggered. The height of the inverted concave frame 32 is higher than the height of the waste filter assembly 4. They will not interfere with each other during lateral movement, so that the waste filter assembly 4 cannot be taken out. In addition to the above method of draining the oil and then cleaning, the waste filter assembly 4 can also be directly pulled out of the oil immersion tank 2. During the upward movement of the coarse filter plate 41 and the fine filter plate 44, the waste in the oil is filtered. It should be noted that the speed should not be too fast, so that the oil does not flow back into the oil immersion tank 2. The operation is simpler and faster. You can choose between these two methods according to your needs.
