Description

Technical Field

[0001] The present application relates to the technical field of mortar production, and specifically discloses a premixed mortar drying device. Background Art

[0002] Premixed mortar is a variety of mortar mixtures produced by specialized manufacturers for use in construction projects. Premixed mortar involves many raw materials. In addition to the commonly used cementitious materials, aggregates, and mineral admixtures, water-retaining and thickening materials, additives, admixtures and other materials must be added according to the performance of the mortar, so that the material composition of the mortar ranges from five or six to more than a dozen. Since the mortar constitutes a unit together with the matrix, as soon as the mortar comes into contact with the matrix, the mortar will absorb water from the matrix, and at the same time, the outer surface of the mortar will evaporate water into the atmosphere. Therefore, the water retention and bonding strength of the mortar are particularly important.

[0003] In the process of producing premixed mortar, the premixed mortar needs to be dried before the dried premixed mortar powder can be packaged in bags and shipped out as bagged finished products. However, the drying effect of the drying devices currently used in the production of premixed mortar on the market is poor. During the drying process, the materials of the premixed mortar are prone to agglomeration, and the materials cannot be fully dried, resulting in a high humidity in the premixed mortar product produced, which reduces the production quality and production efficiency and fails to meet the user's usage needs. Therefore, in view of this, the inventor provides a premixed mortar drying device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that in the process of drying the traditional premixed mortar, the premixed mortar materials in the drying device are easy to agglomerate, which is not conducive to the full drying of the materials and affects the production quality.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides a premixed mortar drying device, comprising a drying barrel for accommodating premixed mortar materials, a supporting box for supporting the drying barrel, and a drying component for drying the premixed mortar materials in the drying barrel, wherein a feeding cylinder is provided at one end of the top of the drying barrel, and a discharging component for discharging the dried materials in the drying barrel is provided between the supporting box and the bottom of the drying barrel. The drying barrel is also provided with a stirring component for preventing the premixed mortar materials from agglomerating. The stirring component comprises a motor installed at the bottom of the drying barrel, a rotating shaft coaxially connected to the output end of the motor and rotatably connected to the bottom end of the drying barrel, a spiral stirring blade provided at the upper half of the rotating shaft, a plurality of fixed stirring rods evenly vertically arranged on the inner bottom surface of the drying barrel, and a plurality of rotating stirring rods evenly distributed in an annular manner in the middle of the rotating shaft. A plurality of movable stirring rods that can rotate between the fixed stirring rods are evenly and equidistantly provided at the bottom of the rotating stirring rod. The drying component comprises a plurality of electric heating rods respectively installed on the side surfaces of the spiral stirring blades, the side surfaces of the fixed stirring rods, and the side surfaces of the movable stirring rods.

[0006] The principles and effects of this basic solution are:

[0007] 1. Compared with the prior art, the present invention is provided with a stirring member, and the motor drives the spiral stirring blades and the movable stirring rod on the rotating shaft to rotate simultaneously. First, the spiral stirring blades located in the upper half of the rotating shaft are used to preliminarily stir the premixed mortar material entering the drying barrel from the feed cylinder, and then the movable stirring rod located in the lower half of the rotating shaft is used to rotate between the fixed stirring rods to stir the premixed mortar material entering the bottom of the drying barrel more finely. At the same time, by providing the sides of the spiral stirring blades, the sides of the fixed stirring rods and the sides of the movable stirring rods, the stirring member can be further stirred. The electric heating rod is installed to facilitate the thorough stirring of the premixed mortar materials and prevent them from agglomerating, while also heating and drying the premixed mortar materials in contact with the spiral stirring blades, the fixed stirring rod and the movable stirring rod. The premixed mortar materials are fully dried during the process of stirring contact driven by the high-speed motor, which greatly improves the drying efficiency, ensures the quality of the finished product of the premixed mortar, and solves the problem that the premixed mortar materials in the drying device of the traditional premixed mortar are easily agglomerated during the drying process, which is not conducive to the full drying of the materials and affects their production quality.

[0008] Furthermore, the drying barrel includes a barrel cover and a bottom plate that are detachably connected to the top of the support box. A fixed stirring rod is provided on the bottom plate. A motor is detachably mounted on the outer bottom of the bottom plate, and the bottom end of the rotating shaft is rotatably connected to the bottom plate. The detachable connection between the bottom plate and the barrel cover facilitates the discharge of the premixed mortar from the drying barrel.

[0009] Furthermore, the fixed stirring rods are arranged in an equidistant annular array on the baseplate. The fixed stirring rods located at the same radius around the rotation axis form a group of annular stirring assemblies, and any movable stirring rod can rotate between two adjacent groups of annular stirring assemblies. By distributing the fixed stirring rods in an annular array on the baseplate, the movable stirring rods can rotate between the rings, stirring the premixed mortar on the baseplate more evenly and thoroughly.

[0010] Furthermore, the bottom plate is detachably and slidably connected to the bottom of the barrel cover body, the top of the support box is provided with a material trough for accommodating the bottom plate, the top of the rotating shaft is provided with a limit plate located below the top of the barrel cover body, the top surface of the limit plate can be fitted and connected with the inner top surface of the barrel cover body, the top of the limit plate is provided with a guide rod, the top of the barrel cover body is provided with a through hole for accommodating the guide rod, the guide rod is slidably and sealedly connected to the inner side wall of the through hole, the discharging part includes an electric telescopic rod and a controller symmetrically arranged between the inner bottom of the support box and the bottom of the bottom plate, and the motor, electric heating rod and electric telescopic rod are all electrically connected to the controller. By providing the guide rod, through hole and electric telescopic rod, it is convenient to adjust and control the lifting movement of the bottom plate, thereby realizing the height adjustment of the bottom plate, and then regulating the closed stirring and open unloading states of the drying barrel, which is easy to operate. By providing the limit plate, the vertical position of the rotating shaft is limited, and the stability of the rotating shaft structure is improved at the same time.

[0011] Furthermore, the inner bottom of the support box is provided with a material guide boss located directly below the bottom plate, and the bottom end of the electric telescopic rod is mounted on the material guide boss. The material guide boss facilitates the accumulation and stacking of dried premixed mortar materials in the support box, making it more convenient to collect the premixed mortar materials after drying.
