Description

Technical Field

[0001] The utility model relates to the technical field of ore grinding, in particular to a temperature-controlled storage barrel and a release agent spraying system. Background Art

[0002] Mold release agents are chemical agents used to prevent materials from sticking to the mold during the molding process. They are widely used in industries such as plastics, rubber, metal casting, and composites. Their core function is to form a barrier that ensures smooth demolding of the product while protecting the mold surface and extending its life.

[0003] In the casting industry, a release agent spraying system is required to spray the mold before casting to aid in cooling and demolding the product. Release agents are typically stored in barrels, which often require specific functionalities in different application scenarios. The barrels used to hold release agents in release agent spraying systems are typically single-layer plastic or metal barrels that lack insulation and temperature control. When the ambient temperature is low, the release agent temperature within the barrel is also relatively low. Once the release agent is sprayed onto the mold, it rapidly lowers the mold temperature after preheating, affecting the fluidity of the high-temperature molten metal in the mold. This can lead to quality issues such as uneven product thickness and increased internal bubbles.

[0004] Based on this, the utility model designs a temperature-controlled storage barrel, which satisfies the insulation and temperature control functions by improving the structure of the release agent storage barrel to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0027] Example 1

[0028] See also Figure 1-4 , the utility model provides a technical solution:

[0029] A temperature-controlled storage barrel includes a barrel body 10, which is a closed cylindrical barrel consisting of a top surface, a bottom surface and a circumferential side surface. The top surface of the barrel body 10 is provided with an inlet and outlet 20, which is provided on the top surface and communicates with the inner cavity of the closed cylindrical barrel. The inlet and outlet 20 is provided with a cover.

[0030] The circumferential wall of the barrel 10 is a sandwich structure, which includes an inner corrosion-resistant layer 11, an intermediate combined temperature control layer 12 and an outer protective layer 13; specifically:

[0031] The inner corrosion-resistant layer 11 is the structural layer in contact with the release agent. To prevent corrosion, the base of the inner corrosion-resistant layer 11 is made of stainless steel, and the inner surface is coated with a high-temperature corrosion-resistant coating. The main components of the coating are nano-powder, ceramic microbeads, silicon carbide, boron nitride, fine-grained alumina, ultrafine zinc oxide, titanium oxide, etc., which are made into metal ceramic functional fillers to improve the wear resistance and corrosion resistance of the coating.

[0032] The middle combined temperature control layer 12 includes a frame type temperature control pipeline 121 and a thermal insulation filler plate 122, wherein the thermal insulation filler plate 122 is made of polyurethane thermal insulation material, which can isolate the external low temperature and keep the release agent warm; the thermal insulation filler plate 122 is an arc-shaped plate structure, which is inlaid between the frame type temperature control pipeline 121 to form a filling interlayer; the frame type temperature control pipeline 121 includes a liquid inlet pipe 1213, a liquid outlet pipe 1214 and a plurality of annular connecting pipes 1215, and the plurality of annular connecting pipes 1215 are arranged in parallel at intervals, and the liquid inlet pipe 1213 and the liquid outlet pipe 1214 are connected and arranged on the left and right sides of each connecting pipe 1215. The structural design of the frame type temperature control pipeline 121 can ensure that The circulating medium can flow evenly horizontally at each height position of the barrel body, uniformly heating the release agent in the barrel. On the other hand, the frame structure fits the cylindrical wall of the barrel body to avoid design, and can be used as a rigid skeleton to enhance the structural strength of the barrel body 10. At the same time, each insulation filler plate 122 is separated into small sizes for easy production; the upper ends of the liquid inlet pipe 1213 and the liquid outlet pipe 1214 are respectively provided with a liquid inlet 1211 and a liquid outlet 1212, and the liquid inlet 1211 and the liquid outlet 1212 extend out of the barrel body 10. The liquid inlet 1211 and the liquid outlet 1212 are connected to the external circulating temperature control system, and the high-temperature medium circulates to heat the release agent in the temperature-controlled storage barrel, thereby realizing heating and temperature control of the release agent.

[0033] The outer protective layer 13 is the surface layer of the temperature-controlled storage barrel, which is made of stainless steel and has an outer surface spray-painted and printed with an appearance pattern.

[0034] Example 2

[0035] A release agent spraying system, comprising the temperature-controlled storage barrel of embodiment 1, characterized in that it further comprises a spraying part 1 and a temperature-control part 2;

[0036] The spraying part 1 includes a spraying pipeline 101, a spraying booster pump 102 and an atomizing nozzle 103. The spraying booster pump 102 is connected in series to the spraying pipeline 101. The input end of the spraying pipeline 101 extends into the inner cavity of the barrel 10 through the inlet and outlet 20, and the output end of the spraying pipeline 101 is connected to the atomizing nozzle 103.

[0037] During operation, a sufficient amount of release agent is pre-filled in the temperature-controlled storage barrel, and the release agent is preheated to a suitable temperature. The spray booster pump 102 is then started according to the frequency rhythm of the casting process to pump the release agent in the temperature-controlled storage barrel to the atomizing nozzle 103 through the spraying pipeline 101, and sprayed into the mold cavity of the casting mold through the atomizing nozzle 103. Due to the preheating treatment of the release agent, the effect on the temperature drop of the mold is smaller than that of the release agent that has not been preheated. Therefore, the problem of uneven thickness and increased bubbles in the product caused by excessive "cooling" of the mold can be improved.

[0038] The temperature control part 2 includes a flow line 201, a return line 202, a circulation pump 203, a temperature control medium tank 204 and a temperature control device 205. The flow line 201 is connected between the temperature control medium tank 204 and the liquid inlet 1211, the return line 202 is connected between the liquid outlet 1212 and the temperature control medium tank 204, the circulation pump 203 is connected in series to the flow line 201, and the temperature control device 205 is arranged in the temperature control medium tank 204. The temperature control device 205 is an electrically controlled heating device, and the heating temperature can be adjusted by electrical control; the circulating medium is generally suitable for clean water. If special heat exchange efficiency or high temperature requirements are required, it can be replaced with other fluid media that meet the corresponding characteristics.

[0039] During operation, the temperature of the temperature control device 205 is adjusted according to the working conditions, and the circulating medium in the temperature control medium tank 204 is heated. After being heated to the required temperature, the circulation pump 203 can be started to pump the circulating medium in the temperature control medium tank 204 through the deflow pipeline 201 to the frame-type temperature control pipeline 121 of the temperature control storage barrel. The high-temperature medium circulates in the frame-type temperature control pipeline 121, and the release agent inside the temperature control storage barrel can be heated in the form of heat exchange. The temperature control medium after the heat exchange is then discharged into the temperature control medium tank 204 through the return pipeline 202, thereby forming a pipeline circulation, and continuously heating and controlling the temperature of the release agent inside the temperature control storage barrel.
