Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, specifically an online water bath heating system. Background Technology

[0002] In existing technologies, because the freezing point / melting point of some chemical raw materials deviates from the temperature at the production site, the raw materials need to be heated to a liquid state before entering the production process. Take titanium complex 726 as an example; its freezing point or melting point is 28°C, and it is solid at low temperatures, especially in winter. Traditionally, it is placed in a constant-temperature oven and baked until melted before use. This baking process is lengthy, and the constant-temperature oven uses electric heating wires, which pose a fire hazard should a leak occur. Summary of the Invention

[0003] In order to solve the above-mentioned problems in the prior art, this utility model proposes an online water bath heating system, which adapts the heating and feeding of raw materials to the production flow, as detailed below.

[0004] An online water bath heating system is characterized by comprising a coarse melting device, a fine melting device, and a temporary storage device connected in sequence by material pipelines;

[0005] The roughing device includes a material pool, a melting cylinder, and a circulating water pipe; there are one or more melting cylinders made of heat-conducting material (stainless steel), which are placed in the material pool, and the bottom of the material pool is the discharge port; the circulating water pipes made of heat-conducting material surround the outer wall of the melting cylinder; and multiple discharge holes are distributed on the bottom surface of the melting cylinder.

[0006] The fine melting device includes a water bath, and a heat-conducting material (stainless steel) material pipe passes through the water bath. The inlet of the material pipe is connected to the outlet of the coarse melting device.

[0007] The temporary storage device includes a storage cylinder, which is made of heat-conducting material and is placed inside an insulated water tank; the inlet of the storage cylinder is connected to the outlet of the material pipe.

[0008] In this system, the raw material is first placed in a melting cylinder, where hot water circulating in a water pipe heats the solid raw material. During heating, the solid raw material gradually melts, at which point the liquid raw material mixed with small particles of solid material detaches from the solid raw material and flows into the material pool through the discharge port (the size of the small particles is determined by the diameter of the discharge port). Then, it enters the material pipe through the discharge outlet. The material pipe is further heated in a water bath, further melting the small particles of solid material until they are completely liquefied, after which they enter the storage cylinder. The storage cylinder is temporarily used for storage in a water bath environment (e.g., a heatable hot water tank) for later use.

[0009] Furthermore, the material pool is closed; the top surface of the melting cylinder is connected to an airtight cover that can be opened and closed; and there is a material pressurization mechanism inside the melting cylinder.

[0010] In this structure, the raw materials are isolated from the outside environment during production, preventing external contamination or pollution. The pressure mechanism forces the molten / semi-molten raw materials out of the molten charge cylinder, improving production efficiency.

[0011] Specifically, the pressure applying mechanism is either a gas pressure applying mechanism or a mechanical pressure applying mechanism;

[0012] The gas pressurization mechanism is as follows: an air valve is installed on the airtight cover, and the air valve is connected to an external high-pressure gas source;

[0013] The mechanical pressure mechanism is as follows: a cylinder is installed inside the airtight cover. The cylinder body is connected to the airtight cover. The piston rod of the cylinder faces downward and its end is connected to a pressure plate. The shape of the pressure plate corresponds to the radial cross-sectional shape of the molten material cylinder. The edge of the pressure plate is in close contact with the side wall of the molten material cylinder.

[0014] Furthermore, the water bath is sealed and equipped with a heating device; the feed tube inside the water bath is spiral-shaped, with the feed end facing upwards and the discharge end facing downwards.

[0015] In this structure, the spiral-shaped feed tube increases the path of the raw material in the water bath; as the hot water rises, the water temperature at the top is slightly higher than that at the bottom, so the raw material is first heated at a higher temperature, which promotes the melting of small solid particles.

[0016] Furthermore, there is a screen inside the discharge end of the feed pipe, and the screen is located inside the water bath.

[0017] In this structure, some unmelted small solid raw materials remain in the water bath and gradually melt under the scouring of the liquid raw materials at a higher temperature.

[0018] Furthermore, a check valve is connected to the outlet of the material pipe; the inlet of the storage cylinder is at its bottom.

[0019] Furthermore, the storage cylinder is made of flexible material; the insulated water tank is sealed and is connected to a hot water inlet and an outlet.

[0020] With this structure, when there is a lot of raw material in the storage cylinder, the water in the insulated water tank is squeezed out; when there is a lot of raw material in the storage cylinder, the water in the insulated water tank is drawn in. This can effectively stabilize the discharge rate of the raw material and achieve a temporary storage function. At the same time, if it is necessary to increase the discharge rate, the water in the insulated water tank can be pressurized, for example, by using a water pump to force water into the insulated water tank.

[0021] Compared to existing technologies, this system is suitable for use in continuous production processes. It heats raw materials using water or circulating water via a water bath heating principle. The electric heating or other heating devices used for water heating are isolated from the raw materials, preventing fire hazards. Even if raw materials leak, they will only mix with water and hydrolyze, without encountering open flames. Unlike constant-temperature ovens, this system avoids the safety hazards and potential fires that can occur if the machine malfunctions, causing temperature control failure and continuous heating.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] refer to Figures 1-4 An online water bath heating system includes a coarse melting device 1, a fine melting device 2, and a temporary storage device 3 connected in sequence by material pipelines; these three devices can be installed on a frame 20 at the production site.

[0029] See again Figure 2 The coarse melting device includes a material pool 4, a melting cylinder 5, and a circulating water pipe 6; there are one or more melting cylinders made of heat-conducting material, which are placed in the material pool, and the bottom of the material pool is the discharge port; a circulating water pipe made of heat-conducting material (used to connect hot water to heat the raw materials in the cylinder) surrounds the outer wall of the melting cylinder; multiple discharge holes 7 are distributed on the bottom surface of the melting cylinder; in this example, the bottom of the material pool is inclined, and the discharge port is located at the lowest end to facilitate the discharge of raw materials.

[0030] See again Figure 3 The fine melting device includes a water bath 11, and a heat-conducting material material pipe 12 passes through the water bath. The inlet of the material pipe is connected to the outlet of the coarse melting device.

[0031] See again Figure 4 The temporary storage device includes a storage cylinder 15, which is made of heat-conducting material and is located inside an insulated water tank 15; the inlet 17 of the storage cylinder is connected to the outlet of the material pipe.

[0032] In this example:

[0033] refer to Figure 2 The material pool 4 is closed; the top surface of the melting cylinder 5 is connected to an airtight cover 8 that can be opened and closed, which can be screwed or snapped; there is a material pressure mechanism inside the melting cylinder.

[0034] The pressure application mechanism can be a gas pressure application mechanism or a mechanical pressure application mechanism; a gas pressure application mechanism consists of an air valve installed on the airtight cover, which is connected to an external high-pressure air source. (See reference...) Figure 2 In this example, the mechanical pressure mechanism is as follows: a cylinder 9 is installed inside the airtight cover. The cylinder body is connected to the airtight cover. The piston rod of the cylinder faces downward and its end is connected to a pressure plate 10. The shape of the pressure plate corresponds to the radial cross-sectional shape of the molten material cylinder. The edge of the pressure plate is in close contact with the inner wall of the molten material cylinder.

[0035] refer to Figure 3 The water bath 11 is sealed and equipped with a heating device (e.g., an electric heater). The feed pipe 12 is spiral-shaped inside the water bath, with the feed inlet side facing upwards and the discharge end side facing downwards. A screen 13 is located inside the discharge end side of the feed pipe, within the water bath. A check valve 14 is connected to the discharge port of the feed pipe.

[0036] refer to Figure 4 The inlet of the storage cylinder 15 is located at its bottom. The storage cylinder is made of flexible material; the insulated water tank is sealed and is connected to a hot water inlet 18 and an outlet 19.

[0037] The walls of the insulated water tank are insulated (e.g., with asbestos or foam plastic). Inside the tank are temperature sensors and electric heaters to ensure the storage temperature of the liquid raw materials. When adjusting the pressure inside the insulated water tank, the incoming water is hot water, and its temperature is basically the same as the water temperature inside the tank.

[0038] This system, when used in the production of titanium complex 726, improves efficiency and feed stability compared to traditional raw material melting methods. This system can also be used for raw materials with similar physical properties. When selecting materials for various components of the system, corrosion-resistant stainless steel is recommended. The material for the storage tank should be a corrosion-resistant soft-film material suitable for liquid raw materials.
