Description

Technical Field

[0001] The present application relates to the field of thermal oil cooling devices, and in particular to a thermal oil cooling device for a reactor for producing modified resins. Background Art

[0002] Reactors are key equipment in the production of modified resins and are often constructed of stainless steel to withstand high-temperature, high-pressure reaction conditions. Modified resin production requires strict temperature control, requiring the reactor to complete resin synthesis at high temperatures while simultaneously requiring rapid cooling to control resin properties. Traditional cooling methods, such as water cooling, suffer from large temperature differences, difficulty controlling cooling rates, and the tendency for uneven resin properties.

[0003] In existing technologies, when thermal oil is exposed to high temperatures for extended periods, oxidation reactions occur. The primary products of this oxidation are alcohols, aldehydes, ketones, esters, and carboxylic acids. As the contact area between the oil and air increases, the oxidation reaction accelerates, affecting the depth of oxidation and the amount of oxides produced. Similarly, the presence of metals and their salts accelerates oil oxidation. Oxidation of thermal oil can lead to oil degradation and reduce heat transfer efficiency.

[0004] Therefore, a heat-conducting oil cooling device for a reaction kettle for producing modified resin is provided. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present invention provides a thermal oil cooling device for a reactor for producing modified resins, which solves the problems raised in the above background technology. To achieve the above purpose, the present invention is implemented through the following technical solutions: A thermal oil cooling device for a reactor for producing modified resins, comprising a water tank, a reactor is arranged on the left side of the water tank, a cooling device for cooling the thermal oil is installed inside the water tank, the cooling device comprises an oil pump, the oil pump is arranged on the side of the water tank, the oil tank is fixedly connected to the inside of the water tank, an oil pipe for transmitting thermal oil is fixedly connected to the outer wall of the oil pump, a first air pump is fixedly connected to the top of the water tank, a first air intake pipe is fixedly connected to the side of the first air pump, a first air injection pipe is fixedly connected to the side of the first air pump, a second air pump is fixedly connected to the top of the water tank, a second air injection pipe is fixedly connected to the side of the second air pump, and a second air intake pipe is fixedly connected to the side of the second air pump.

[0006] Preferably, the oil pipe is connected to the oil tank.

[0007] Preferably, the first air injection pipe is longer than the second air intake pipe.

[0008] Preferably, the water tank is filled with hydroxide, and the oil tank is made of iron.

[0009] Preferably, the water tank is equipped with a scraping device to reduce the steam layer on the top of the oil tank.

[0010] Preferably, the scraping device includes a rotating rod, which is rotatably connected to the side of the inner wall of the water tank through a bearing, the outer wall of the rotating rod is fixedly connected to a fan blade, the side of the rotating rod is fixedly connected to an extrusion block, the top of the oil tank is equipped with a hydraulic tank, the interior of the hydraulic tank is filled with hydraulic oil, and a piston at one end of the hydraulic tank is slidably connected to a first hydraulic rod, and a movable sleeve on the outer wall of the first hydraulic rod is provided with a spring.

[0011] Preferably, a piston at one end inside the hydraulic chamber is slidably connected to a second hydraulic rod, and a scraper block is fixedly connected to the side of the second hydraulic rod.

[0012] The benefits of this application are:

[0013] 1. This application uses an oil pump and an oil pipe to circulate the heat transfer oil in the oil tank. The cold air introduced by the first air pump enters the hydroxide (water) in the water tank through the first air injection pipe. The bubbles generated increase the contact area between water and air, promote heat exchange, and utilize the high specific heat capacity of water to absorb the heat of the heat transfer oil, thereby reducing the temperature of the heat transfer oil in the oil tank, preventing the heat transfer oil from undergoing oxidation reactions due to high temperature to generate substances such as alcohols, aldehydes, ketones, esters, and carboxylic acids, thereby delaying oil deterioration and maintaining its heat transfer efficiency.

[0014] Second, the airflow generated by the first air jet in this application drives the fan blades to rotate, which in turn drives the rotating rod, extrusion block, first hydraulic rod, and other components, ultimately causing the scraper block to move to the right, scraping away the vapor layer on the top of the fuel tank. This vapor layer hinders heat dissipation, and scraping it away enhances the fuel tank's heat dissipation performance and improves cooling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Example 1: See Figure 1-Figure 4 This embodiment provides a thermal oil cooling device for a reactor for producing modified resins, comprising a water tank 1, a reactor 4 being arranged on the left side of the water tank 1, a cooling device 2 for cooling the thermal oil being assembled inside the water tank 1, the cooling device 2 comprising an oil pump 21, the oil pump 21 being arranged on the side of the water tank 1, an oil tank 29 being fixedly connected to the inside of the water tank 1, an oil pipe 22 for transmitting the thermal oil being fixedly connected to the outer wall of the oil pump 21, a first air pump 23 being fixedly connected to the top of the water tank 1, a first air intake pipe 24 being fixedly connected to the side of the first air pump 23, a first air injection pipe 25 being fixedly connected to the side of the first air pump 23, a second air pump 26 being fixedly connected to the top of the water tank 1, a second air injection pipe 27 being fixedly connected to the side of the second air pump 26, and a second air intake pipe 28 being fixedly connected to the side of the second air pump 26.

[0025] The oil pipe 22 is connected to the oil tank 29 .

[0026] The first air injection pipe 25 is longer than the second air intake pipe 28 .

[0027] The water tank 1 is filled with hydroxide, and the oil tank 29 is made of iron.

[0028] When the above-mentioned equipment is used, the oil pump 21 is started to circulate the heat-conducting oil inside the reactor 4 into the oil tank 29 through the oil pipe 22, and the first air pump 23 is started. The external cold air is sprayed into the water tank 1 through the first air suction pipe 24 and the first air jet pipe 25. Since the first air jet pipe 25 penetrates into the hydroxide, bubbles are generated after the gas enters the hydroxide, and the oil tank 29 is cooled by the hydroxide. The bubbles drive the hot air to rise, and the second air pump 26 is started. The second air pump 26 sucks out the hot air inside the water tank 1 through the second air suction pipe 28 and discharges it through the second air jet pipe 27.

[0029] Example 2: See Figure 1-Figure 4 On the basis of the first embodiment, a scraping device 3 for reducing the steam layer on the top of the oil tank 29 is installed inside the water tank 1.

[0030] The scraping device 3 includes a rotating rod 31, which is rotatably connected to the inner wall side of the water tank 1 through a bearing. The outer wall of the rotating rod 31 is fixedly connected to a fan blade 32, and the side of the rotating rod 31 is fixedly connected to an extrusion block 33. A hydraulic chamber 34 is assembled on the top of the oil tank 29, and the hydraulic chamber 34 is filled with hydraulic oil. A first hydraulic rod 35 is slidably connected to the piston at one end of the hydraulic chamber 34, and a spring 36 is provided on the outer wall of the first hydraulic rod 35.

[0031] A second hydraulic rod 37 is slidably connected to a piston at one end of the hydraulic chamber 34 , and a scraper block 38 is fixedly connected to the side of the second hydraulic rod 37 .

[0032] When the above-mentioned equipment is in use, the airflow generated by the first air jet pipe 25 drives the fan blades 32 to rotate, the fan blades 32 drive the rotating rod 31 to rotate, the rotating rod 31 drives the extrusion block 33 to rotate, and the extrusion block 33 drives the first hydraulic rod 35 to descend. When the first hydraulic rod 35 descends, the internal pressure of the hydraulic warehouse 34 increases, driving the second hydraulic rod 37 to move to the right, and the second hydraulic rod 37 drives the scraper block 38 to move to the right. The scraper block 38 scrapes off the steam layer generated on the top of the oil tank 29, thereby further improving the heat dissipation performance of the oil tank 29.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
