Description

Technical Field

[0001] The utility model relates to the technical field of carbon rod sintering, and specifically provides a carbon rod sintering mechanism. Background Art

[0002] A carbon rod filter element is a deep filter element, also known as an activated carbon filter element or CTO filter element. It can effectively remove organic matter, particulates, rust, residual chlorine, odors, etc. from liquids and is often used in water purifiers or filter pools. Carbon rod filter elements are made of high-quality activated carbon as the raw material and then composed of a low-melt adhesive. The main molding processes for carbon rod filter elements include extrusion molding, sintering molding, and wet molding, of which sintering molding is currently the main carbon rod molding process. The sintering molding process includes: material canning, compression, high-temperature sintering, demolding, and cutting. High-temperature sintering is the main step of this process. After the material is filled into the mold and compressed, it is solidified by sintering to form a carbon rod with a certain strength.

[0003] Existing sintering processes utilize ovens or tunnel furnaces. Multiple molds filled with material are placed in the oven or tunnel furnace, where air conducts heat to the material in the molds, solidifying it. However, air's poor thermal conductivity results in a long sintering time for carbon rods, leading to lower production efficiency. This long sintering time also increases mold turnover, requiring a larger number of molds and increasing production costs.

[0004] Accordingly, the art requires a new carbon rod sintering mechanism to solve the above problems. Utility Model Content

[0013] In the preferred technical solution of the above-mentioned carbon rod sintering mechanism, a plurality of second positioning holes are provided on the clamp, and the thermocouples are cooperatively inserted into the second positioning holes.

[0014] In the preferred technical solution of the above-mentioned carbon rod sintering mechanism, a heat-insulating layer is provided on the outer surface of the clamp.

[0015] In the preferred technical solution of the above carbon rod sintering mechanism, the carbon rod sintering mechanism further includes a driving assembly, and the driving assembly is used to drive the two clamps to clamp or release the mold.

[0016] In the preferred technical solution of the above carbon rod sintering mechanism, the driving assembly includes at least two cylinders, and the output ends of the cylinders are connected to the clamps to drive the two clamps to clamp or release the mold; or

[0017] The driving assembly includes a frame, a driving motor, a double-ended screw, a guide rod, a first slider, a second slider, a first connecting rod provided on the first slider, and a second connecting rod provided on the second slider, wherein the first connecting rod and the second connecting rod are connected to the two clamps in a one-to-one correspondence;

[0032] In order to solve the problem that the existing sintering equipment makes the sintering time of carbon rods longer, resulting in low production efficiency of carbon rods, and because of the long sintering time, the mold circulation cycle is long, a large number of molds are required, and the production cost is increased.

[0033] like Figures 1 to 4 As shown, this embodiment discloses a carbon rod sintering mechanism for heating a mold 6 containing a material to solidify the material into a carbon rod. The carbon rod sintering mechanism includes a drive assembly, a plurality of clamps 1, a heating element, and a thermocouple 3. The plurality of clamps 1 cooperate to cover the mold containing the material. The drive assembly drives the clamps 1 to move, so that the clamps 1 clamp or release the mold 6. At least some of the plurality of clamps 1 are equipped with at least one heating element and a thermocouple. The temperature of the heating element is controlled by the thermocouple, and the clamp is heated by the heating element. The clamp transfers heat to the mold to heat the material.

[0034] In this embodiment, there are two clamps 1, with the mold 6 positioned between them. A drive assembly can be used to move the two clamps 1 toward or away from each other, thereby clamping or releasing the mold 6. The clamps 1 are rectangular and made of a material with good thermal conductivity, such as aluminum, alloy, or stainless steel, to improve thermal conductivity between the clamps 1 and the mold 6.

[0035] like Figure 1 and Figure 2As shown, the fixture 1 is provided with a plurality of first positioning holes 12 and second positioning holes 13. A heating element is inserted and secured within the first positioning holes 12, and a thermocouple 3 is inserted and secured within the second positioning holes 13. The heating element is a heating rod 2, and thermocouples 3 are provided in a one-to-one correspondence with each heating rod 2. The thermocouples 3 are used to adjust the temperature of the corresponding heating rod 2, thereby achieving more precise control over the temperature of each heating rod 2. The heating rods 2 evenly transfer heat to the fixture 1 within the first positioning holes 12, allowing the fixture 1 to reach the set temperature more quickly and accurately.

[0036] like Figure 1 and Figure 2 As shown, a thermal insulation layer is fixed to the outer surface of the clamp 1. In this embodiment, the thermal insulation layer is fixed to the outer surface of the clamp 1 on the side facing away from the mold 6. The thermal insulation layer can be made of asbestos, aluminum foil, or rock wool, etc., to reduce the heat loss of the mold 6 and make the temperature of the clamp 1 more stable. A plurality of positioning grooves 11 are evenly provided on the opposite sides of the two clamps 1. The shape of the positioning grooves 11 matches the shape of the mold 6. When the mold 6 is heated, the mold 6 is placed in the positioning grooves 11 one by one and clamped by the two clamps 1. The clamp 1 transfers heat to the mold 6, and the mold 6 transfers heat to the material, causing the material to solidify and form a carbon rod.

[0037] The fixture 1 is in direct contact with the mold 6 to transfer heat to the mold 6, and heat is transferred between the solid fixture 1 and the mold 6 by heat conduction. Compared with the prior art in which an oven or a tunnel furnace transfers heat to the air, and the air then transfers the heat to the mold 6, the fixture 1 is in direct contact with the mold 6 to transfer heat, which can improve the thermal conductivity efficiency, shorten the sintering time, and improve production efficiency. At the same time, due to the shortening of the sintering time, the circulation cycle of the mold 6 is shortened, the number of molds 6 can be reduced, and the production cost can be reduced. In addition, the position of the mold 6 can be determined by the positioning groove 11, and the contact area between the fixture 1 and the mold 6 can be increased, which can further improve the thermal conductivity efficiency between the fixture 1 and the mold 6, and at the same time make the mold 6 more evenly heated, thereby improving production quality.

[0038] like Figure 3 and Figure 4 As shown, the carbon rod sintering mechanism also includes a heat-resistant member 5. The heat-resistant member 5 can be made of a hard heat-resistant material. The heat-resistant member 5 is fixed to the fixture 1. The output end of the drive assembly is connected to the heat-resistant member 5. The connection method is not limited to plugging, bonding or clamping. The drive assembly drives the heat-resistant member 5 to move, thereby driving the fixture 1 to move. A connector can also be fixed to the fixture 1, and the heat-resistant member 5 is fixed on the connector. The output end of the drive assembly is connected to the heat-resistant member 5. The drive assembly drives the heat-resistant member 5 and the connector to move, thereby driving the fixture 1 to move. The heat-resistant member 5 can reduce the heat transferred from the fixture 1 to the drive assembly, reduce the possibility of damage to the drive assembly due to high temperature, and enable the drive assembly to operate more stably.

[0039] like Figure 3 As shown, the drive assembly includes a frame 41 and at least two cylinders 42. In this embodiment, the number of cylinders 42 is set to two, and both cylinders 42 are mounted on the frame 41. A first connecting rod 48 is fixed to the output end of one of the cylinders 42, and the first connecting rod 48 is fixedly connected to the heat-resistant part 5 on one of the clamps 1; a second connecting rod 49 is fixed to the output end of the other cylinder 42, and the second connecting rod 49 is fixedly connected to the heat-resistant part 5 on the other clamp 1. When it is necessary to heat the mold 6, the two cylinders 42 are started at the same time, so that the two clamps 1 move toward each other until the mold 6 is clamped in the positioning groove 11. The clamp 1 transfers heat to the mold 6, and the mold 6 transfers heat to the material to achieve sintering and solidification of the material. After heating is completed, the two cylinders 42 are started at the same time, so that the two clamps 1 move away from each other to achieve the release of the mold 6. The mold 6 can be loaded or unloaded by existing equipment, and the mold 6 can be moved between the two clamps 1 and wait for the clamps 1 to clamp, or the mold 6 can be transferred after the clamps 1 release the mold 6.

[0040] like Figure 4 As shown, as another preferred embodiment, the drive assembly includes a frame 41, a drive motor 43, a double-headed screw 44, a guide rod 45, a first slider 46, a second slider 47, a first connecting rod 48 and a second connecting rod 49, the first end of the first connecting rod 48 is fixed to the first slider 46, the second end of the first connecting rod 48 is fixed to the heat-resistant part 5 of one of the clamps 1, the first end of the second connecting rod 49 is fixed to the second slider 47, and the second end of the second connecting rod 49 is fixed to the heat-resistant part 5 of the other clamp 1.

[0041] The drive motor 43 is mounted on the frame 41. The double-ended screw 44 is rotatably connected to the frame 41 and coaxially connected to the output shaft of the drive motor 43. The guide rod 45 is fixed to the frame 41 and arranged parallel to the double-ended screw 44. The double-ended screw 44 can be driven to rotate by the drive motor 43. The first slider 46 and the second slider 47 both slide through the guide rod 45. The first slider 46 is threadedly connected to the left-handed thread section of the double-ended screw 44, and the second slider 47 is threadedly connected to the right-handed thread section of the double-ended screw 44. Controlling the forward and reverse rotation of the drive motor 43 can drive the double-ended screw 44 forward and reverse, causing the first slider 46 and the second slider 47 to move toward or away from each other, thereby driving the two clamps 1 to clamp or release the mold 6.

[0042] If it is necessary to heat the mold 6, the drive motor 43 is started to rotate forward, and the first slide 46 and the second slide 47 move toward each other, driving the two clamps 1 to move until the mold 6 is clamped in the positioning groove 11. The clamp 1 transfers heat to the mold 6, and the mold 6 transfers heat to the material, achieving sintering and solidification of the material. After heating is completed, the drive motor 43 is started to rotate backward, and the first slide 46 and the second slide 47 move away from each other, driving the two clamps 1 to move, thereby releasing the mold 6. Of course, the movement of the clamps can also be achieved by cooperating with a motor, gear, and rack assembly, which will not be described in detail here.

[0043] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
