Description

Technical Field

[0001] This utility model relates to a sealing device, and more particularly to an adjustable automatic lubrication sealing feed device for a cooler. Background Technology

[0002] Aluminum fluoride coolers are used to cool high-temperature aluminum fluoride. The high-temperature aluminum fluoride enters the cooler cylinder through the feed device. Traditional feed sealing devices use a fish-scale structure seal, which has a large gap with the cylinder and poor sealing effect. Furthermore, the fish-scale seal wears down after friction with the cylinder friction ring, making the sealing effect between the feed device and the cylinder even worse. Replacing the fish-scale seal requires a long downtime, which is labor-intensive, time-consuming, and costly. Replacing the scales also affects the operation of the cooler, resulting in a reduction in production capacity. Utility Model Content

[0003] The technical problem to be solved by this utility model is: the good sealing performance of the feeding device and the cooling cylinder of the high-temperature aluminum fluoride cooler, and the problem of severe wear and difficulty in replacement of the feeding sealing device during production and use.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] An adjustable automatic lubrication and sealing feeding device for a cooling machine includes a cooling cylinder. The feeding end of the cooling cylinder is provided with a feeding end cylinder flange, and a feeding port body is provided on the feeding end cylinder flange. The feeding end cylinder flange and the cooling cylinder flange on the cooling cylinder are connected together by bolts, thereby connecting the feeding port body to the cooling cylinder. The connection between the feeding end cylinder flange and the cooling cylinder flange facilitates quick maintenance and replacement in the later stages, improving production efficiency.

[0006] The feed inlet body includes a dynamic sealing ring, a static sealing ring, a feed cylinder, and a fixing frame. One end of the feed cylinder is connected to the fixing frame, and the other end extends into the cooling cylinder and is clearance-fitted with the inner ring hole of the feed end cylinder flange. The dynamic sealing ring is disposed on the outer surface of the feed end cylinder flange, and the static sealing ring is fitted onto the feed cylinder. An axial sealing adjustment mechanism is provided between the static sealing ring and the fixing frame to allow the end face of the static sealing ring to slide and seal against the dynamic sealing ring. A radial sealing adjustment mechanism is provided between the static sealing ring and the feed cylinder to allow the inner ring surface of the static sealing ring to seal against the outer ring surface of the feed cylinder. The feed cylinder is provided with a feed inlet.

[0007] Furthermore, the axial sealing adjustment mechanism includes an adjusting screw, a first spring seat, a compression spring, a second spring seat, and a guide rod. One end of the compression spring is disposed inside the first spring seat, and the other end is disposed inside the second spring seat. The adjusting screw is disposed inside the compression spring along the radial direction of the compression spring, and both ends of the adjusting screw extend out of the corresponding first spring seat and second spring seat. The adjusting screw can move freely on the first spring seat, the second spring seat, and inside the compression spring. The fixing frame is provided with a first spring seat mounting hole for mounting the first spring seat. The static sealing ring is provided with adjusting screw mounting holes corresponding to the first spring seat mounting holes. Each first spring seat mounting hole contains a corresponding first spring seat. One end of each adjusting screw extends out of the corresponding first spring seat mounting hole, and the other end extends out of the corresponding adjusting screw mounting hole. An adjusting nut is provided on the adjusting screw between the second spring seat and the adjusting screw mounting hole.

[0008] The first spring seat is fixed in the first spring seat mounting hole, and the second spring seat can move freely. When it is necessary to adjust the axial gap between the static sealing ring and the dynamic sealing ring, it is only necessary to adjust the position of the adjusting bolt on the adjusting screw. The tension of the compressed spring can be used to push the static sealing ring towards the dynamic sealing ring, thereby increasing the fit between the static sealing ring and the dynamic sealing ring and making the sealing performance better. Moreover, this operation can adjust the sealing gap at any time during the operation of the equipment, so as to achieve the purpose of adjusting the gap without stopping the machine.

[0009] Furthermore, the fixing frame is also provided with a first guide rod mounting hole symmetrical about the center point of the feed cylinder. The static sealing ring is provided with a second guide rod mounting hole at a position corresponding to the first guide rod mounting hole. A guide rod travel sleeve is also provided between the first guide rod mounting hole and the second guide rod mounting hole on the same straight line. The guide rod travel sleeve is fixed on the outer ring surface of the feed cylinder. One end of the guide rod is set in the first guide rod mounting hole, and the other end passes through the guide rod travel sleeve and is set in the second guide rod mounting hole, and is fixed by the guide rod fixing nut.

[0010] The function of the guide rod is to ensure that the adjustment direction does not deviate when the axial sealing adjustment mechanism is adjusted, so that the adjustment can be carried out smoothly.

[0011] Furthermore, the radial sealing adjustment mechanism includes an oil-impregnated PTFE packing and a sealing gland. The oil-impregnated PTFE packing and the sealing gland are arranged side by side between the static sealing ring and the outer ring surface of the feed cylinder. One side of the sealing gland extends out of the lower end face of the static sealing ring. Fixing holes are evenly distributed on the extended sealing gland. Double-ended bolts are installed in the fixing holes. One end of the double-ended bolt is set on the static sealing ring, and the other end extends out of the fixing hole and is fixed by a fixing nut.

[0012] Adjusting the position of the fixing nut on the double-ended bolt allows the sealing gland to press against the oil-impregnated PTFE packing, causing the packing to expand and compact the sealing gap between the static sealing ring and the outer ring surface of the feed cylinder. This achieves radial sealing performance of the sealing device, ensuring a tight seal between the sealing ring and the feed cylinder, and preventing leakage of materials and dust from inside the cylinder. This operation allows for adjustment of the sealing gap at any time during equipment operation, achieving the goal of adjusting the gap without stopping the machine.

[0013] Furthermore, the dynamic sealing ring is provided with an oil groove, and the static sealing ring is provided with an oil filling hole. When the static sealing ring and the dynamic sealing ring are in sliding sealing contact, the oil filling hole is connected to the oil groove. Oil is injected into the oil groove through the oil filling hole by the oil supply device through the oil guide pipe, so that the contact surface between the dynamic sealing ring and the static sealing ring has sufficient lubrication. This ensures the overall sealing performance of the equipment and allows the dynamic sealing ring to rotate flexibly with the cylinder, reducing wear.

[0014] Furthermore, the feed cylinder is provided with an inclined sealing baffle to facilitate feeding, and the fixing frame is connected to an external support frame, which provides support force.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model utilizes an axial sealing adjustment mechanism to adjust the sealing performance of the entire sealing device in the axial direction, and a radial sealing adjustment mechanism to adjust the sealing performance of the entire sealing device in the radial direction. This ensures the overall sealing performance between the feeding device and the cylinder, and also ensures that the gap between the sealing device and the cylinder can be adjusted at any time during use without stopping the machine. This reduces downtime for sealing replacement and manual maintenance, saves costs, and improves equipment production efficiency.

[0017] 2. In this utility model, the oil supply device injects oil into the oil tank through the oil filling hole via the oil guide pipe, so that the contact surface between the dynamic sealing ring and the static sealing ring is sufficiently lubricated, which can ensure the overall sealing performance of the equipment and allow the dynamic sealing ring to rotate flexibly with the cylinder to reduce wear.

[0030] An axial sealing adjustment mechanism is provided between the static sealing ring 6 and the fixed frame 8. The axial sealing adjustment mechanism includes an adjusting screw 13, a first spring seat 14, a compression spring 15, a second spring seat 16, and a guide rod 17.

[0031] The fixed frame 8 is provided with a pair of first guide rod mounting holes symmetrical about the center point of the feed cylinder 7. The static sealing ring 6 is provided with a second guide rod mounting hole at the corresponding position of the first guide rod mounting hole. A guide rod stroke sleeve 18 is also provided between the first guide rod mounting hole and the second guide rod mounting hole on the same straight line.

[0032] The mounting bracket 8 has four first spring seat mounting holes on each side of the paired first guide rod mounting holes for mounting the first spring seat 14. The static sealing ring 6 has an adjusting screw mounting hole corresponding to each of the eight first spring seat mounting holes. Each of the eight first spring seat mounting holes contains a first spring seat 14, and one end of the adjusting screw 13 on each corresponding first spring seat 14 can pass through the corresponding first spring seat mounting hole. The other end of the adjusting screw 13 passes through the corresponding compression spring 15 and second spring seat 16 in sequence before extending into the paired first spring seat 14 on the static sealing ring 6. The adjustment screw 13 is fixed in the corresponding adjustment screw mounting hole and three adjustment nuts 20 are provided on the adjustment screw 13 between the corresponding second spring seat 16 and the adjustment screw mounting hole. One end of the compression spring 15 is fixed inside the first spring seat 14 and the other end is fixed inside the second spring seat 16. The adjustment screw 13 is arranged inside the compression spring 15 in the radial direction of the compression spring 15, and both ends of the adjustment screw 13 extend out of the corresponding first spring seat 14 and second spring seat 16. The adjustment screw 13 can move freely on the first spring seat 14 and second spring seat 16 and inside the compression spring 15.

[0033] A radial sealing adjustment mechanism is provided between the static sealing ring 6 and the feed cylinder 7. The radial sealing adjustment mechanism includes an oil-impregnated PTFE packing 21 and a sealing gland 22. The oil-impregnated PTFE packing 21 and the sealing gland 22 are arranged side by side between the static sealing ring 6 and the outer ring surface of the feed cylinder 7.

After the material enters from the feeding port 25, it enters the cylinder through the inclined sealing flange. The fixing frame 8 is connected to the external support frame so that the entire device can be stably fixed on the support frame.

[0035] When adjusting the sealing performance of the device during operation, if the axial sealing performance needs adjustment, simply adjust the position of the adjusting bolt 2 on the adjusting screw 13. The tension of the compression spring 15 will push the static sealing ring 6 towards the dynamic sealing ring 5, thereby increasing the fit between the static sealing ring 6 and the dynamic sealing ring 5 and improving the axial sealing performance between them. If the radial sealing performance needs adjustment, simply adjust the position of the fixing nut 24 on the double-ended bolt 23. This will cause the sealing gland 22 to press against the oil-impregnated PTFE packing 21, causing the oil-impregnated PTFE packing 21 to expand and compact the static seal. The sealing gap between ring 6 and the outer ring surface of the feed cylinder 7 is used to achieve the radial sealing performance of the sealing device, ensuring a tight seal between the sealing ring and the feed cylinder 7, and preventing leakage of materials and dust inside the cylinder. The sealing gap can be adjusted at any time during equipment operation, achieving the purpose of adjusting the gap without stopping the machine. If lubrication is required, oil can be injected into the oil tank through the oil filling hole 10 using the oil supply device 11 and the oil guide pipe 12, so that the contact surface between the dynamic sealing ring 5 and the static sealing ring 6 has sufficient lubrication, which can ensure the overall sealing performance of the equipment and allow the dynamic sealing ring 5 to rotate flexibly with the cylinder to reduce wear.
