Abstract
Description
Technical Field
[0001] This utility model relates to the field of disc dryer technology, and in particular to a disc dryer for the production of silicone resin adhesives. Background Technology
[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to disc dryers is also constantly improving. Disc dryers are mechanical equipment that uses heat energy to reduce the moisture content of materials and are used to dry objects. The production process of silicone resin adhesives requires the use of disc dryers for drying.
[0003] Currently, when using a disc dryer to dry silicone resin adhesives, the dried silicone resin adhesive is discharged from the discharge pipe. Some silicone resin adhesive is easily left on the inner wall of the discharge pipe. As a result, when using the disc dryer, silicone resin adhesives dried separately in two adjacent cycles are easily mixed together, which can reduce the purity of the silicone resin adhesive and is not conducive to the drying process of silicone resin adhesives. Utility Model Content
[0004] The purpose of this invention is to address the following shortcomings in the prior art: the inner wall of the discharge pipe is prone to leaving some silicone resin adhesive residue, which leads to the phenomenon that silicone resin adhesive from two separate drying processes tends to mix together when the disc dryer is used, easily reducing the purity of the silicone resin adhesive and hindering the drying process. Therefore, this invention proposes a disc dryer for silicone resin adhesive production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A disc dryer for producing silicone resin adhesive includes a disc dryer body, a discharge pipe fixedly connected to the disc dryer body, two sliders slidably connected to the discharge pipe, each slider having an insert rod inserted therein, and the two insert rods being connected by a fixing ring.
[0007] The inner wall of the fixed ring is fixedly connected to two mounting blocks, and each mounting block is fixedly connected to a scraper. The surface of the scraper is in contact with the inner wall of the discharge pipe. Each slider is provided with a locking component, and the fixed ring is provided with a rotating component.
[0008] Preferably, each slider has a concave cross-section, each locking assembly includes two threaded rods threaded onto the lower surface of the slider, each threaded rod is fixedly connected to a limit block, and each insert has two slots for connecting the limit blocks.
[0009] Preferably, the outer surface of the discharge pipe is provided with an annular groove, and each slider is slidably connected to the annular groove.
[0010] Preferably, the rotating assembly includes a rotating rod rotatably mounted on the fixed ring, and a sealing plate is fixedly sleeved on the outer side of the rotating rod.
[0011] Preferably, one end of the rotating rod is slidably connected to an L-shaped rod, the rotating rod has a rectangular opening for the L-shaped rod to slide back and forth, a round rod is fixedly connected to the L-shaped rod, and a perforated plate is fixedly connected to the rotating rod.
[0012] Preferably, a first sealing ring is fixedly connected to the upper surface of the fixing ring, and a second sealing ring is fixedly connected to the outer surface of the sealing plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In use, first change the sealing plate from a horizontal to an inclined state. Then, slide the two sliding ports along the annular groove, which will drive the fixing ring to rotate. The two scrapers will slide against the inner wall of the discharge pipe to scrape off the residual silicone resin adhesive accumulated on the inner wall of the discharge pipe. Under the action of gravity, the adhesive will move downward and detach from the discharge pipe. Then, manually rotate each limiting block. After rotation, each limiting block will be located outside the bayonet. Then, manually pull down the fixing ring to separate the fixing ring and the two scrapers from the discharge pipe. This facilitates the cleaning of the scrapers and sealing plate and effectively avoids the phenomenon of silicone resin adhesive mixing together after two separate drying processes. This effectively ensures the high purity of the silicone resin adhesive and is beneficial to the drying process of the silicone resin adhesive. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.
[0023] Reference Figures 1-5 A disc dryer for producing silicone resin adhesive includes a disc dryer body 1. A discharge pipe 2 is fixedly connected to the disc dryer body 1. Two sliders 3 are slidably connected to the discharge pipe 2. Each slider 3 has an insert rod 5 inserted into it. The two insert rods 5 are connected by a fixing ring 4. Two mounting blocks 16 are fixedly connected to the inner wall of the fixing ring 4. Each mounting block 16 has a scraper 15 fixedly connected to it. The surface of the scraper 15 is in contact with the inner wall of the discharge pipe 2. Each slider 3 is provided with a locking component. The fixing ring 4 is provided with a rotating component.
[0024] Each slider 3 has a concave cross-section. Each locking assembly includes two threaded rods 6 threaded onto the lower surface of the slider 3. Each threaded rod 6 is fixedly connected to a limiting block 7. Each insert rod 5 has two slots 9 for connecting the limiting blocks 7. The outer surface of the discharge pipe 2 has an annular groove 13. Each slider 3 is slidably connected to the annular groove 13. The annular groove 13 can restrict the movement trajectory of the two sliders 3, and the sliders 3 cannot detach from the annular groove 13, but can only slide along the annular groove 13. In the initial state, the surface of each insert rod 5 is in contact with the surface of the corresponding slider 3, and the surface of each limiting block 7 is in contact with the upper inner wall of the corresponding slot 9, which can effectively prevent the insert rod 5 and the slider 3 from moving relative to each other.
[0025] The rotating assembly includes a rotating rod 14 rotatably mounted on a fixed ring 4. A sealing plate 17 is fixedly sleeved on the outer side of the rotating rod 14. An L-shaped rod 11 is slidably connected to one end of the rotating rod 14. A rectangular opening is provided on the rotating rod 14 for the L-shaped rod 11 to slide back and forth. A round rod 12 is fixedly connected to the L-shaped rod 11. A perforated plate 10 is fixedly connected to the rotating rod 14. In the initial state, one end of the round rod 12 passes through the corresponding round hole on the perforated plate 10, and the rubber sleeve fixed to the outer surface of the round rod 12 is tightly attached to the inner wall of the round hole, which can effectively prevent the round rod 12 from contacting the inner wall of the round hole. The perforated plate 10 is detached at will. The L-shaped rod 11 is manually pulled to make it slide relative to the rotating rod 14 until the round rod 12 is detached from the perforated plate 10. Then the L-shaped rod 11 is rotated. Since the cross-section of the L-shaped rod 11 is rectangular and one end of the L-shaped rod 11 is slidably set in the rectangular opening, the rotation of the L-shaped rod 11 will drive the rotating rod 14 to rotate. After the sealing plate 17 rotates, it will change from a horizontal state to an inclined state, so that the silicone resin adhesive inside the discharge pipe 2 can be discharged through the gap between the sealing plate 17 and the inner wall of the discharge pipe 2.
[0026] A first sealing ring is fixedly connected to the upper surface of the fixing ring 4, and a second sealing ring 8 is fixedly connected to the outer surface of the sealing plate 17. The first sealing ring is in close contact with the lower surface of the discharge pipe 2, and the first sealing ring is located between the discharge pipe 2 and the fixing ring 4, which can effectively improve the sealing performance when the fixing ring 4 is connected to the discharge pipe 2. When the sealing plate 17 is in a horizontal state, the second sealing ring 8 on the outer surface of the sealing plate 17 is in close contact with the inner wall of the discharge pipe 2, which can effectively ensure the sealing performance when the sealing plate 17 is connected to the discharge pipe 2.
[0027] In this invention, during use, the sealing plate 17 is first changed from a horizontal state to an inclined state. Then, the insert rod 5 is rotated, causing the two sliders 3 to slide along the annular groove 13, which in turn drives the fixing ring 4 to rotate. Under the transmission action of the two mounting blocks 16, the two scraper strips 15 will slide tightly against the inner wall of the discharge pipe 2, so as to scrape off the residual silicone adhesive on the inner wall of the discharge pipe 2 and make it move downward under the action of gravity and detach from the discharge pipe 2. Then, each limiting block 7 is manually rotated to return to the initial state. Each limiting block 7 has its surface in contact with the upper inner wall of the corresponding bayonet 9. After each limiting block 7 is rotated, it will be located on the outside of the bayonet 9. Then, manually pull down the fixing ring 4 to separate the fixing ring 4 and the two scrapers 15 from the discharge pipe 2, so as to clean the scrapers 15 and the sealing plate 17. This effectively avoids the phenomenon of silicone resin adhesive being mixed together after two separate drying processes, thus ensuring the high purity of the silicone resin adhesive and facilitating the drying process of the silicone resin adhesive.
