The inventor finds out through multiple practices that: because of the particularity of the concrete material, the concrete stops stirring or the temperature is reduced again after stirring to cause the concrete to be formed or frozen on the inner wall of the stirring cylinder, so that the thickness of the inner wall of the stirring cylinder is increased, and the later heating and stirring treatment on the concrete with different models is not facilitated. The conventional stirring drum can be removed by manual scraping or by means of tools, but the operation has great damage to the inner wall of the stirring drum.
Therefore, the inventor develops the heating type concrete stirring device convenient to clean and the cleaning method thereof, and ensures that the damage to the inner wall of the stirring cylinder is greatly reduced during cleaning.
As shown in fig. 1, a heating type concrete mixing device convenient for cleaning, includes: the stirring device comprises a stirring drum 1, wherein an end cover 4 is arranged at the top end of the stirring drum 1, and a feeding port 2 is arranged on one side of the end cover 4. The bottom of the mixing drum 1 is an inverted frustum 3, and a discharge hole is formed in the center of the inverted frustum 3.
The outer wall department parcel of churn 1 has heating mechanism, and shown heating mechanism not only carries out heat treatment to the inside of churn 1 when being used for the stirring, still is used for when clearing up churn 1 simultaneously, and the solidification is heated at the concrete of 1 inner wall of churn and is the flocculation form, and the clearance of being convenient for reduces the dynamics of striking off to the inner wall of protection churn 1. The central position department of end cover 4 is provided with actuating mechanism, actuating mechanism and rabbling mechanism transmission are connected, the rabbling mechanism sets up the inside of churn 1.
When the stirring, heating mechanism carries out heat treatment in to churn 1, and the rabbling mechanism mixes the concrete mixing, arranges the material and accomplishes or need when clearing up 1 inner wall of churn, adds water in to churn 1, and heating mechanism lasts the heating, and the solidification is heated at the concrete of 1 inner wall of churn and is the flocculation form, and frustum 3 through the inversion slides down along churn 1 discharges from the discharge gate.
The heating that has now generally adopts the heating pipe, and the heating pipe is the heliciform winding in the outer wall department of churn 1, and is close to each other, when the heating, then can lead to the hot gas flow to influence each other because the heating pipe is close to too, and the intensification leads to the fact the inside of churn 1 to be heated inhomogeneous rapidly, therefore the inventor has made following improvement to heating mechanism: the heating mechanism includes: the heating device comprises a connecting ring 5 fixed at the top of the mixing drum 1, a heating body 11 tightly attached to the outer wall of the inverted frustum 3, and a plurality of heat conduction pipes connected between the connecting ring 5 and the heating body 11; the end cover 4 is positioned in the connecting ring 5, and the heat conduction pipe is tightly attached to the outer wall of the stirring cylinder 1 and used for heat transfer.

The adjacent heat conduction pipes are spaced and have the same size, so that the influence between the adjacent heat conduction pipes is reduced, and the heating stability is improved. The heating element 11 is arranged at the bottom, so as to heat the bottom of the mixing drum 1 at first, and mainly considers that the amount of bottom materials is large and the amount of top materials is small in the using process, so that the requirement of the materials on heat is met. Simultaneously when later stage clearance, need heating mechanism heating to make the concrete of solidification at 1 inner wall of churn be heated and be the flocculation form, also consider the more condition of bottom material when receiving the influence of gravity and stirring, the bonding material of the inside department that so lies in the below is more, consequently need do heat treatment at the very first time.
But if only by the heating back, the concrete that will solidify at 1 inner wall of churn is heated and is the flocculation form, can not guarantee to be clean up 1 inner wall of churn, also can only the clearance part.
Therefore, the inventor improves the stirring mechanism: the stirring mechanism includes: the stirring shaft 12 is provided with a plurality of hinged components arranged on the stirring shaft 12, a connecting rod 13 in transmission connection with the hinged components, and a stirring blade 14 fixed at the tail end of the connecting rod 13; when the concrete is stirred, the hinge assembly controls the included angle between the connecting rod 13 and the stirring shaft 12 to be 55-80 degrees; when the inner wall of the stirring drum 1 needs to be cleaned, the hinge assembly controls the included angle between the connecting rod 13 and the stirring shaft 12 to be 85-90 degrees, and the clearance distance between the stirring blade 14 and the stirring drum 1 is 0.2-0.8 cm; during stirring, the stirring blades 14 do not contact the inner wall of the stirring cylinder 1 and have no influence, when the stirring blades 14 need to be cleaned, the included angle between the connecting rod 13 and the stirring shaft 12 is opened to 85-90 degrees from 55-80 degrees under the control of the hinge assembly (the opening angle needs to be determined according to the thickness of concrete on the inner wall of the stirring cylinder 1 until the concrete can be opened to the maximum), the stirring blades 14 are contacted with the concrete on the inner wall of the stirring cylinder 1 and rotate at the same time, and the stirring blades 14 at the moment are scraping blades to scrape the concrete adhered to the inner wall of the stirring cylinder 1.
