Embodiment 1

[0027] Such as figure 1 As shown, the sand mixer of the present invention has a base 1 and a main mixing bin 2 installed on the base. Three feeding ports 3 are installed on the upper part of the main mixing bin 2, which can be used to supply different types of molding sand such as new sand and old sand. It can also be used to supply molding sand, binder and auxiliary materials at the same time. The above-mentioned feed port 3 is also connected with a quantitative feeding device (not shown in the figure) with a metering function. The primary mixing disc is used for preliminary mixing of the materials supplied by the feed port. The primary mixing disc includes a primary mixing drive mechanism 4, a primary mixing transmission shaft 5 and a rotating disc installed on the primary mixing transmission shaft. The primary mixing transmission shaft 5 passes through the main mixing The top of the bin 2 is connected to the primary mixing drive mechanism 4 located outside the top of the ma...

Embodiment 2

[0036] As an improvement to the present invention, in this embodiment, for the initial mixing disc, more than two first-stage rotating disks 6 at the same level can be set, and each first-stage rotating disk 6 is connected with the second-stage rotating disk. 7 different speeds and steering movements, such as figure 2 As shown, the transmission connection can be realized in the following way: the original hybrid transmission shaft is divided into a driving transmission shaft and several driven transmission shafts, each first-stage rotating disc 6 has its own independent driven transmission shaft, and the shaft end Connect the driven gear 17, the shaft end of the driving transmission shaft of the second stage rotating disk 7 is connected to the driving gear 18, the driving transmission shaft drives the driving gear 18 to rotate under the drive of the primary mixing drive mechanism 4, and the driving gear 18 drives the driven gear 17 to rotate , the driven gear 17 drives the dr...

Embodiment 3

[0039] Different from Embodiment 2, as an improvement to the primary mixing disk of the present invention, in this embodiment, the differential speed control of the first-stage rotating disk 6 and the second-stage rotating disk 7 can be realized without adding a new shaft position, Such as image 3 As shown, the transmission connection can be realized in the following way: the original mixed transmission shaft is divided into the inner shaft of the active transmission and the outer shaft of the driven transmission, the second-stage rotating disk 7 is connected to the inner shaft of the active transmission, and the first-stage rotating disk 6 is connected to the driven transmission shaft. Drive the outer shaft, the shaft end of the active transmission inner shaft is connected to the driving gear 18, the shaft end of the driven transmission outer shaft is connected to the ring gear 19, the driving transmission inner shaft drives the driving gear 18 to rotate under the drive of th...

Abstract

The invention relates to a sand mixer with an enhanced preliminary mixing function. The sand mixer is provided with an intelligent composite material inlet, wherein a multi-stage preliminary mixing disk for preliminarily mixing supplied materials is mounted on a main mixing bin; by the adoption of an optimized curved surface material throwing structure with a rotating speed and a rotating direction which are different from the rotating speed and the rotating direction of a main mixing mechanism, a load can be scientifically distributed according to an actual requirement; by the independent design of the mechanical loads and power of a preliminary mixing mechanism and the main mixing mechanism, the mechanical effect is effectively enhanced; a special material conveying opening for supplying an adhesive and / or a curing agent is formed in the middle part or the lower part of the main mixing bin of the sand mixer, so that the workload and the working time of the main mixing mechanism can be reduced to an extremely large extent, and the workload of the preliminary mixing mechanism is also reduced; furthermore, the sand mixer realizes controllability of production from quantitative material feeding and precise temperature control, and equipment works safely and reliably.

Description

technical field [0001] The invention relates to a casting machine, in particular to a sand mixer with the function of enhancing primary mixing. Background technique [0002] The material used for molding in casting is molding sand, which is generally made of molding materials such as raw sand, binders and auxiliary materials mixed in a certain proportion. Sand mixers are sand processing equipment used to realize the mixing of the above-mentioned molding sand materials. Sand mixers are often divided into several categories according to the sand mixing process: roller sand mixers mainly for rolling and rubbing; The main vane type sand mixer; the countercurrent or rotor type sand mixer with rubbing and mixing functions and the balance wheel type sand mixer with rolling and mixing functions. In practical applications, due to the different use occasions and mixing purposes, more extensive and flexible means such as stirring, rolling, shaking, turning or a combination thereof are...
