Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a small material feeding device suitable for stirring in a medium and small dry-mixed mortar production line. Background Technique

[0002] The small materials in the dry-mixed mortar formula account for a small proportion of the main materials, only 1-5%. The small materials are directly batch-fed manually or with the assistance of machinery, and as a result, it is very difficult to stir them evenly in a short time. Generally, in order to stir evenly, each batch is stirred for more than 10 minutes, and some even reach 15-20 minutes. Even so, it is still difficult to ensure even stirring, which greatly affects the product quality. While in a large production line, the stirring time for each batch is 3-4 minutes, and some currently only need 2 minutes to stir evenly to meet the product quality requirements (uniformity is greater than or equal to 95%). In response to the above problems, the technical personnel of our company have conducted repeated research and made technological innovations in the method of adding small materials. This device sprays small materials on the stirred main materials in a pulsed manner within 60-90 seconds, ensuring a stirring time within 4 minutes and enabling the mortar uniformity to meet the requirements.

[0003] Currently, in response to the problem of uneven stirring, the solution given by many manufacturers or experts is to first expand the small materials by more than 10 times to become masterbatch, and then manually put them into the mixer. Although this is much better, since the production of the small materials themselves is increased, the production cost is increased and the production efficiency is reduced.

[0004] While a large production line adopts a computer-aided automatic weighing and feeding system device, but the cost of this system is equivalent to the cost of a medium and small production line, which is out of reach for small and micro enterprises. In view of this, in response to the above problems, in-depth research has led to the generation of this case. Content of the Utility Model

[0005] The purpose of the utility model is to provide a small material feeding device suitable for stirring in a medium and small dry-mixed mortar production line, so as to solve the problem that the existing small material feeding device suitable for stirring in a medium and small dry-mixed mortar production line cannot stir evenly in a short time when the addition amount of the dry-mixed mortar auxiliary materials relative to the main materials is very small as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A small material feeding device suitable for stirring in a medium and small dry-mixed mortar production line, including a mixer body, a weighing sensor and a stirring blade. A control panel is installed on the outer wall of one end of the mixer body. The main materials for stirring by the mixer are arranged inside the mixer body. A small material feeding funnel is installed on the top end of the mixer body;

[0007] One side of the top of the mixer body is equipped with a pressure relief cap, and a stirring structure is installed on the inner wall of the mixer body, and two groups of stirring structures are provided.

[0008] Preferably, the stirring structure includes a mounting shaft, the mounting shaft is installed on the inner wall of the mixer body, and stirring blades are evenly installed on the outer wall of the mounting shaft, and the number of the stirring blades is set to twelve.

[0009] With the above technical solution, by setting two groups of stirring structures, the stirring is made faster and more uniform by the twelve stirring blades of the two groups.

[0010] Preferably, pulse-sprayed minor materials are arranged above the main materials to be stirred by the mixer. The front view of the pulse-sprayed minor materials shows a vertical distribution and fall, and the side view shows an umbrella-shaped distribution and fall.

[0011] With the above technical solution, the minor materials with uniform feeding make the time for full mixing with the main materials shorter.

[0012] Preferably, weighing sensors are evenly installed on the outer wall above the minor material feeding funnel, and the number of the weighing sensors on the minor material feeding funnel is set to three.

[0013] With the above technical solution, the minor materials are accurately weighed by the weighing sensors to ensure the accurate ratio with the main materials.

[0014] Preferably, a temporary storage cavity for minor materials is arranged inside the minor material feeding funnel, a diversion plate is installed below the temporary storage cavity for minor materials, and a cloth bin is arranged below the diversion plate.

[0015] With the above technical solution, by arranging the diversion plate to guide the falling direction of the minor materials, the distribution is made more uniform.

[0016] Preferably, a sealing flange is installed below the minor material feeding funnel through fastening bolts, and a pneumatic valve is installed on one side of the sealing flange.

[0017] With the above technical solution, through the connection of the sealing flange, a sealed connection between the minor material feeding funnel and the pneumatic valve is realized.

[0018] Preferably, a compressed air source connector is arranged on the outer wall below the minor material feeding funnel, and one side of the compressed air source connector is connected to an external 4-6 kg compressed air source.

[0019] With the above technical solution, the pulse operation is realized by connecting the compressed air source connector to an external 4-6 kg compressed air source.

[0020] Compared with the prior art, the beneficial effects of the present utility model are:

[0021] (1) The present utility model provides a temporary storage chamber for small materials and a weighing sensor. By pouring small materials into the temporary storage chamber for small materials and precisely weighing the poured small materials through the weighing sensor, the proportioning of the main materials and small materials is made precise, ensuring the use effect and solving the problem of inaccurate proportioning.

[0022] (2) The present utility model provides a small material feeding funnel, a feeding bin and a pneumatic valve. By putting various prepared small materials into the temporary storage chamber of the small material feeding funnel at one time and pressing the electrical start control button on the control panel, at this time, the pneumatic valve opens, and the small materials enter the feeding bin and are preliminarily dispersed in the feeding bin through the diversion plate. Press the closing button of the pneumatic valve, and at the same time, the interlocked pulse control circuit is connected, and the compressed air solenoid valve opens. The solenoid valve controlled by the pulse sprays small materials once every 3 - 10 seconds, and the spraying time can be adjusted arbitrarily, such as 20 seconds. In this way, the main materials and the sprayed small materials start to be mixed, and are stirred and mixed by the installation shaft driving multiple stirring blades. The stirring efficiency is high and uniform, achieving small investment, quick results, improving production efficiency, reducing production costs, ensuring product quality, and solving the problems of low work efficiency and high costs.
