Description

Technical Field

[0001] The present application relates to the technical field of phenolic resins, and in particular to a feeding device for phenolic resin production. Background Art

[0002] Phenolic resin is originally a colorless or yellowish-brown transparent substance. It is often sold on the market with colorants to appear in red, yellow, black, green, brown, blue and other colors. It is in granular or powder form and is resistant to weak acids and weak bases. It decomposes when exposed to strong acids and corrodes when exposed to strong bases. It is insoluble in water but soluble in organic solvents such as acetone and alcohol. It is obtained by the condensation of phenolic formaldehyde or its derivatives.

[0003] The existing patent (publication number: CN220657447U) discloses a phenolic resin feeding and insulation device. The device comprises a pipeline connecting a storage tank and a weighing tank, with multiple heat-conducting pipes spaced apart and equipped with heating devices. The pipeline consists of a water pipe and a joint, with the heat-conducting pipes connected between the water pipes and the joints. The heating devices heat the heat-conducting pipes, thereby heating the medium inside. After traveling a certain distance within the pipeline, the heated medium reaches another heat-conducting pipe, where it is heated again, raising the temperature. This prevents freezing of phenol and formaldehyde solutions, which can cause blockages in long pipelines. The heat-conducting pipes and heating devices are convenient to install, reducing costs. The heat-conducting pipes are connected between the water pipes and the joints. They are installed simultaneously with the pipeline during installation. For maintenance and replacement, the heat-conducting pipes can be removed by disconnecting the joints. This makes installation, repair, and replacement easy, saving time and effort, and reducing installation, maintenance, and operating costs.

[0004] The above-mentioned document can keep the phenolic resin warm when it is being fed, preventing it from freezing and affecting the transportation of the phenolic resin. However, when in use, the knobs need to be turned in sequence to make multiple heat-conducting blocks contact the heat-conducting layer. The installation is relatively cumbersome and inconvenient to repair and maintain. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present application provides a feeding device for phenolic resin production, which has advantages such as improved practicality and solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a feeding device for phenolic resin production, comprising a connecting tube, the inner wall of the connecting tube is installed with a plurality of heat-conducting plates, the outer surface of the connecting tube is provided with two groups of heat-conducting plates, each group of the heat-conducting plates is fixedly connected to a fixed frame on a side away from each other, and a plurality of the fixed frames are internally provided with heating wires, the outer surface of the connecting tube is fixedly connected to a shell, each group of the fixed frames is fixedly connected to a sliding rod on a side away from each other, and the plurality of sliding rods are slidably plugged into the shell, the outer surface of the shell is rotatably connected to a rotating part, and the inner wall of the rotating part is fixedly connected to a plurality of arc blocks.

[0007] According to the above solution, by installing the rotating member in conjunction with the arc block and the slide rod, the plurality of heat conducting plates can be brought into contact with the outer surface of the connecting pipe by simply rotating the rotating member during use.

[0008] Furthermore, a side surface of each group of the fixing frames that is away from each other is fixedly connected to a spring, and the other ends of the plurality of springs are fixedly connected to the inner wall of the shell.

[0009] According to the above solution, the spring is installed so that when the connecting pipe is replaced, the deformation force of the spring can drive the multiple heat conducting plates away from the connecting pipe, thereby facilitating the replacement of the connecting pipe.

[0010] Furthermore, both left and right ends of the connecting pipe are provided with external connecting pipes, and both of the external connecting pipes are connected to the connecting pipe through flanges.

[0011] According to the above solution, by using flanges to connect the external pipes, the sealing performance can be improved, which facilitates the transportation of materials.

[0012] Furthermore, two groups of symmetrical teeth are fixedly connected to the inner wall of the rotating member, and elastic clamping plates are installed on the left and right side surfaces of the shell, and the two elastic clamping plates are in contact with the teeth adjacent to them.

[0013] Through the above solution, the cooperation between the installed elastic clamping plate and the teeth can limit the rotating part, thereby avoiding the instability of the rotating part during use.

[0014] Furthermore, a plurality of handles are fixedly connected to the outer surface of the rotating member, and the plurality of handles are distributed in a circular pattern.

[0015] Through the above solution, providing multiple handles can facilitate the user to rotate the rotating member, so that the multiple rotating members can drive the arc block to revolve.

[0016] Furthermore, a pulley is installed at one end of each group of sliding rods that is away from each other, and the plurality of arc-shaped blocks are in contact with the pulley close to them.

[0017] Through the above solution, installing the pulley can make it easier for the arc block to push the slide rod to slide, thereby avoiding grinding between the slide rod and the arc block.

[0018] Furthermore, the plurality of heat conducting plates are all configured to be arc-shaped and fit closely with the outer surface of the connecting pipe.

[0019] According to the above solution, the heat conducting plate is configured in an arc shape so as to be easily fitted with the outer surface of the connecting pipe, thereby facilitating temperature transfer.

[0020] Furthermore, the connecting pipe is made of a heat-conducting material, and the plurality of heat-conducting plates are distributed in a circular pattern.

[0021] Through the above solution, the provision of the heat conducting sheet can facilitate the transfer of temperature to the interior of the connecting pipe, thereby preventing low temperature from affecting the fluidity inside the connecting pipe.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] This feeding device for phenolic resin production can make multiple heat-conducting plates contact the outer surface of the connecting pipe by installing a rotating part in cooperation with an arc block and a sliding rod. Therefore, the heat generated by the heating wire can be transferred to the connecting pipe through the heat-conducting plate and diffused to the interior of the connecting pipe through the multiple heat-conducting sheets, thereby avoiding poor circulation caused by low temperature. The cooperation of multiple sliding rods with a fixed frame and the heat-conducting plates can make it fit for use with pipes of different diameters. At the same time, when the multiple heat-conducting plates are in contact with the connecting pipe, a double-layer cavity is generated inside, which further improves the thermal insulation performance and thus improves the overall practicality.

By installing the rotating member The cooperation between the part 8 and the arc block 9 and the sliding rod 7 allows the multiple heat-conducting plates 3 to contact the outer surface of the connecting pipe 1 by simply rotating the rotating part 8 during use, so that the heat generated by the heating wire 5 can be transferred to the connecting pipe 1 through the heat-conducting plate 3, and diffused to the interior of the connecting pipe 1 through the multiple heat-conducting sheets 2, thereby avoiding poor circulation caused by low temperature. The cooperation of multiple sliding rods 7 with the fixed frame 4 and the heat-conducting plate 3 can make it fit for use with pipes of different diameters. At the same time, when the multiple heat-conducting plates 3 are in contact with the connecting pipe 1, a double-layer cavity will be generated inside, which further improves the thermal insulation and thus improves the overall practicality.

[0032] See also Figure 1 、 Figure 2 、 3 , each group of fixed frames 4 are fixedly connected to a side surface away from each other with a spring 10, and the other ends of the multiple springs 10 are fixedly connected to the inner wall of the shell 6. Installing the spring 10 can facilitate the replacement of the connecting pipe 1. The deformation force of the spring 10 drives the multiple heat conducting plates 3 to move away from the connecting pipe 1, which is convenient for replacing the connecting pipe 1. External pipes 11 are provided at both ends of the connecting pipe 1. The two external pipes 11 are connected to the connecting pipe 1 through flanges. By using flanges to connect the external pipes, the sealing can be improved, which facilitates the transportation of materials.

[0033] See also Figure 1 、 Figure 2 、 4 The outer surface of the rotating member 8 is fixedly connected to a plurality of handles 14, and the plurality of handles 14 are distributed in a circular pattern. The provision of a plurality of handles 14 can facilitate the user to rotate the rotating member 8 so that the plurality of rotating members 8 can drive the arc blocks 9 to revolve. A pulley 15 is installed at the end of each group of slide rods 7 away from each other, and the plurality of arc blocks 9 are in contact with the pulley 15 close to them. Installing the pulley 15 can facilitate the arc block 9 to push the slide rod 7 to slide, thereby avoiding grinding between the slide rod and the arc block 9. The plurality of heat conducting plates 3 are all arranged in an arc shape and fit with the outer surface of the connecting tube 1.

By installing a rotating part 8 and cooperating with an arc block 9 and a sliding rod 7, it is only necessary to rotate the rotating part 8 during use to make multiple heat-conducting plates 3 contact the outer surface of the connecting pipe 1, so that the heat generated by the heating wire 5 can be transferred to the connecting pipe 1 through the heat-conducting plate 3 and diffused to the interior of the connecting pipe 1 through multiple heat-conducting sheets 2, thereby avoiding poor circulation due to low temperature. By cooperating with multiple sliding rods 7, a fixed frame 4 and a heat-conducting plate 3, it can be used with pipes of different diameters.

[0035] The working principle of the above embodiment is as follows: when in use, first rotate the rotating member 8 through the handle 14, so that the rotating member 8 drives the multiple arc blocks 9 to contact with the pulley 15, and pushes the multiple slide bars 7 to slide in the shell 6. At this time, the multiple slide bars 7 can push the multiple heat conducting plates 3 to contact with the connecting pipe 1, and then the heating wire 5 is energized and generates heat, so that the heat can be transferred from the heat conducting plate 3 to the connecting pipe 1, and then transferred to the multiple heat conducting plates 2 through the connecting pipe 1, so that the temperature can be gathered inside the connecting pipe 1, thereby avoiding poor circulation caused by low temperature. By installing the rotating member 8 and the arc blocks 9 and the slide bars 7 The cooperation can make multiple heat-conducting plates 3 contact with the outer surface of the connecting tube 1 by rotating the rotating part 8 during use, so that the heat generated by the heating wire 5 can be transferred to the connecting tube 1 through the heat-conducting plate 3, and diffused to the inside of the connecting tube 1 through the multiple heat-conducting sheets 2, thereby avoiding poor circulation caused by low temperature. Through the cooperation of multiple sliding rods 7, the fixed frame 4 and the heat-conducting plate 3, it can be used with pipes of different diameters. At the same time, when multiple heat-conducting plates 3 are in contact with the connecting tube 1, a double-layer cavity will be generated inside, which further improves the thermal insulation and thus improves the overall practicality.
