The spacing component includes a spacer 20. A plurality of spacers 20 are arranged in the insulation chamber 12. The condenser 13 passes through the plurality of spacers 20 and extends to the outside of the insulation shell 10. The spacer 20 abuts against the mixing barrel 11. The spacer 20 forms a plate with an L-shaped cross-section. The vertical parts of the spacer 20 respectively abut the inner wall of the insulation shell 10 and the outer wall of the mixing barrel 11. The bottom of the mixing barrel 11 falls on the horizontal extension part of the spacer 20. The vertical part of the spacer 20 is at the same height as the insulation chamber 12. The length of the horizontal extension part of the spacer 20 is less than the outer diameter of the mixing barrel 11. A plurality of identical spacers 20 are arranged in a circular array on the outside of the mixing barrel 11. The insulation chamber 12 for insulation is formed between the insulation shell 10 and the mixing barrel 11. A plurality of spacers are arranged in the insulation chamber 12 The partition 20 falls on the top of the horizontal bent part of the multiple spacers 20 through the mixing barrel 11, and the vertical part of the spacer 20 contacts the outer wall of the mixing barrel 11, so that the condenser 13 can greatly increase the contact surface area with the mixing barrel 11, and improve the heat exchange effect with the mixing barrel 11. For the preparation of mud at the construction site, the stirring temperature of the mud can be adjusted according to needs, and the coagulation speed of the mud can be controlled. It has higher adaptability and flexibility of use for the construction site, which is helpful for the actual preparation of construction mud. Secondly, the mixing barrel 11 is supported by multiple spacers 20, so that the mixing barrel 11 is not in direct contact with the insulation shell 10, and the design of the spacer 20 extending to the bottom of the mixing barrel 11 can enable the mud in the mixing barrel 11 to exchange heat with the side walls and bottom of the insulation shell 10 at the same time, promote the temperature consistency of the slurry, and improve the phenomenon of local temperature overheating.
