DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figures 1 to 4 The assembled waste heat thermal oil boiler shown includes:

[0025] Boiler body;

[0026] The boiler body comprises a base 1, a middle lower furnace body 2, a middle upper furnace body 3 and a top cover 4;

[0027] The base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4 all include a furnace core structure 5 and a furnace wall structure 6. The furnace core structure 5 in the base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4 are all provided with a connecting pipe 7. One end of the connecting pipe 7 away from the furnace core structure 5 passes through the furnace wall structure 6 and extends outward. The outer sides of the middle and lower furnace body 2 and the middle and upper furnace body 3 are provided with an external pipe 8 for connecting the connecting pipe 7. The furnace wall structure 6 includes a steel frame 61 wrapped around the outer side of the furnace core structure 5. The inner cavity of the steel frame 61 is filled with a heat-insulating material 62.

[0028] By dividing the boiler body into four parts, namely, a base 1, a middle and lower furnace body 2, a middle and upper furnace body 3 and a top cover 4, it is convenient to carry out simultaneous processing in the factory, thus shortening the processing time of the boiler body. At the same time, the four-section boiler body reduces the volume of a single section, making transportation and hoisting convenient. Then, the base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4 all adopt an integrated design of a furnace core structure 5 and a furnace wall structure 6, and the installation can be completed after only hoisting and splicing. There is no need to construct the furnace wall structure 6 after the furnace core is assembled in the traditional way. This can reduce the amount of later construction and improve the assembly efficiency of the boiler body.

[0029] The furnace core structure 5 at the joints of the base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4 all extend outward and fit together, and a welding space 9 is formed between the base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the furnace wall structure 6 of the top cover 4. The position of the furnace core structure 5 is limited to ensure that the furnace core structure 5 in the upper and lower boiler bodies fits tightly. At the same time, a welding space 9 is formed between the base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4, which not only facilitates the welding of the upper and lower steel frames 61, but also provides enough space to seal the furnace core structure 5.

[0030] Locating pins 10 are fixed around the top of the steel structure frame 61 on the base 1, the middle and lower furnace body 2 and the middle and upper furnace body 3, and positioning grooves 11 that are engaged with the positioning pins 10 are provided around the bottom of the steel structure frame 61 on the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4. The arrangement of the positioning pins 10 and the positioning grooves 11 facilitates the upper and lower alignment when the base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4 are hoisted and assembled to prevent the internal pipes from being misaligned due to the misalignment of the boiler main structure, which makes it impossible to use them later. At the same time, the positioning grooves 11 are designed in a truncated cone shape, and the top of the positioning pins 10 is chamfered, which can ensure that the boiler main body can be automatically calibrated within a certain range using the positioning pins 10 and the positioning grooves 11.

[0031] A steel plate 12 is arranged in the welding space 9, and an avoidance groove 13 is opened on the steel plate 12 for avoiding the positioning pin 10. The steel plate 12 and the steel structure frame 61 are welded to each other. The welding space 9 can be filled by the steel plate 12, and the furnace wall structure 6 can be completed to prevent heat from being lost too quickly. The avoidance groove 13 can avoid the positioning pin 10 and place the steel plate 12 in the welding space 9.

[0032] A pouring port 14 is provided on the steel frame 61 and is located inside the welding space 9. The design of the pouring port facilitates pouring of the insulation material 62 after assembly, thereby reducing the weight of the boiler body and facilitating transportation and hoisting.

[0033] Lifting ears 15 are welded on both sides of the base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4. The lifting ears 15 are located at the four corners. Through the cooperation of the lifting ears 15, the base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4 are conveniently lifted.

[0034] During specific use, the base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4 are transported from the factory to the boiler assembly point, and then the base 1, the middle and lower furnace body 2, the middle and upper furnace body 3 and the top cover 4 are stacked up and down in sequence by using lifting equipment. During the lifting and stacking process, the upper boiler body cooperates with the positioning pin 10 on the top of the lower boiler body through the positioning groove 11, which is convenient for calibrating and positioning the upper boiler body. After the four sections of the boiler body are lifted and spliced, the furnace core structure 5 at the splicing position is sealed from the welding space 9, and then the insulation material 62 is poured into the steel frame 61 through the pouring port 14 to form a furnace wall structure 6 with the steel frame 61, and then the steel plate 12 is filled in the welding space 9, and the steel plate 12 is welded to the upper and lower boiler bodies by electric welding to quickly complete the assembly of the boiler.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
