Description

Technical Field

[0001] This utility model relates to the technical field of heating equipment for hot melt adhesive kettles, specifically a heat transfer oil heating device for hot melt adhesive kettles. Background Technology

[0002] As the core heating device of the hot melt adhesive reactor, the thermal oil heating system directly affects the quality of adhesive products and production efficiency. In existing technologies, thermal oil electric heaters provide a uniform and stable heat source to the hot melt adhesive reactor through the circulation of thermal oil in the oil tank.

[0003] However, in actual operation, the lack of a filtration structure in the oil filling pipe of traditional oil tanks can lead to the introduction of solid impurities such as metal shavings and dust when adding new oil. These impurities, circulating with the oil circuit, can cause three major problems: (a) clogging of pipes and pump valves; (b) accelerating the deterioration of heat transfer oil; and (c) depositing on the surface of heating elements to form an insulating layer, reducing heat transfer efficiency.

[0004] Therefore, we propose a heat transfer oil heating device for hot melt adhesive kettles. Utility Model Content

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] This embodiment is a heat transfer oil heating device for a hot melt adhesive autoclave.

[0021] like Figure 1-4 As shown, the device includes a thermal oil electric heater 1. An oil tank 2 is provided at one end of the upper outer surface of the thermal oil electric heater 1. An overflow port 3 is provided at one end of the upper outer surface of the oil tank 2. An oil injection pipe 4 is provided at the other end of the upper outer surface of the oil tank 2. A connecting pipe 5 is sealed to the upper part of the oil injection pipe 4 through a flange. A filter structure 7 is provided inside the connecting pipe 5. The filter structure 7 includes an mounting annular plate 9, a coarse filter cylinder 10, a fine filter cylinder 11, a plug ring 12, a fixing ring 13, and a connecting support column 14. An assembly limiting ring 6 is fixedly installed in the upper part of the inner cavity of the connecting pipe 5. A rubber ring 15 is fixedly installed on the lower outer surface of the assembly limiting ring 6. An annular mounting groove 8 is opened at the bottom of the inner cavity of the connecting pipe 5.

[0022] The outer wall of the mounting ring plate 9 and the inner wall of the connecting pipe 5 are connected by insertion, and the outer wall of the insertion ring 12 and the annular mounting groove 8 are connected by insertion. There are four sets of connecting support columns 14, which are fixed between the upper outer surface of the fixing ring 13 and the lower outer surface of the mounting ring plate 9. The coarse filter cartridge 10 is located inside the fine filter cartridge 11, and both the coarse filter cartridge 10 and the fine filter cartridge 11 are fixed to the lower outer surface of the mounting ring plate 9. The fixing ring 13 is fixed to the upper part of the inner cavity of the insertion ring 12. The filtration pore size of the coarse filter cartridge 10 is 180-125μm, and the filtration pore size of the fine filter cartridge 11 is 75-50μm. After the filter structure 7 is inserted into the connecting pipe 5, the rubber ring 15 is squeezed between the upper outer surface of the mounting ring plate 9 and the lower outer surface of the assembly limiting ring 6.
