Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tank cleaning device for a stirring tank used for kneading cement milk and kneading feed for livestock.

[0002]

[Prior Art]

 Conventionally, as a mixing tank for cement milk kneading, a stirring blade was attached to a rotating shaft that was vertically supported at the axial center position in the tank, water and cement supply ports were installed on the tank top plate, and a cement milk outlet was installed on the lower part of the tank side wall. With the structure provided respectively, in use, a predetermined amount of water and cement are supplied to the tank from the above-mentioned supply port, and the mixture is stirred and kneaded by the rotation of the stirring blades, and then one batch of cement milk from the outlet. It is widely used to take out the product from the tank and repeat this process.

[0003]

[Problems to be solved by the device]

 However, in the conventional cleaning of the inside of the tank, after the kneading work of the day is completed, a worker enters the tank and manually cleans it. Since it often solidified already, it took a considerable amount of labor and time to sufficiently remove them. The purpose of this plan is to facilitate cleaning inside the tank.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention supports a stirring shaft with stirring blades, the rotation of which is transmitted from a rotation driving means, in the tank, and at the same time, each tank is provided with a supply port for supplying water and materials. In the tank,

At the upper position in the tank, a water sprinkling blade to be sprinkled mainly on the upper surface of the tank is attached so that rotation can be transmitted from the stirring shaft, and water supplied from the water supply port flows to the water sprinkling blade. We propose a cleaning device for the stirring tank.

In the present invention, the above-mentioned “attaching the water sprinkling blade to the upper position in the tank so that rotation can be transmitted from the stirring shaft” means that the water sprinkling blade is directly fixed to the stirring shaft and the speed is the same as that of the stirring shaft. And a structure in which the water sprinkling blades are rotatably supported on the stirring shaft or the upper part of the tank, and the rotation is transmitted from the stirring shaft via a speed increasing mechanism. An embodiment of the present invention will be described below with reference to the drawings.

[0007]

【Example】

 Fig. 1 shows a stirring tank for mixing cement milk. Bearings (4) and (5) are installed at the centers of the upper plate (2) and the bottom plate (3) of the cylindrical tank body (1), and both bearings ( The stirring shaft (6) is rotatably supported on the shafts (4) and (5), and the shaft (6) is supported vertically to the shaft center in the tank body (1). The stirring blade (7) is mounted on the shaft (6). ) ... is attached, and a cement supply port (8) is provided on one side of the tank upper plate (2) and a water supply port (9) is provided near the center. (10) is a cement charging chute connected to a cement silo, and its charging port is hung down to the cement supplying port (8) of the tank. (11) and (12) are motors and speed reducers installed on the tank top plate (2), from the pulley (13) fixed to the output shaft of the speed reducer (12) to the upper end of the stirring shaft (6). The rotation is transmitted to the pulley (14) fixed to the belt via the belt (15).

The tank cleaning device provided in the above stirring tank is as follows. A water sprinkling blade (16) is fixed to the upper part of the stirring shaft (6) near the bearing (4), and the sprinkling blade (16) is fixed to the stirring shaft (6) in a horizontal state as an example. As shown in Fig. 2, a large number of spirally mounted circular support plates (17) are installed, and the vertical cross section of the blades is appropriately inclined, so that the water supplied is supplied in a horizontal horizontal direction from above. Designed to dissipate in a range of.

As a water guide path to the sprinkler blade (16), a mortar shape that extends above the sprinkler blade (16) and extends to the water supply port (9) around the axis of the stirring shaft (6). The inner mass (18) is attached to the lower surface of the tank upper plate (2), and an annular outlet (19) around the stirring shaft (6) is opened at the center of the bottom surface of the guide mass (18). The water supplied from the supply port (9) is received in the guide mass (18) and is made to flow down from the outlet (19) onto the sprinkler blade (16) and the receiving plate (17).

A pump (21) installed by a bracket (20) on one side of the tank body (1) is connected to the water supply port (9) by a pipe (22). Water is supplied from a water storage tank (not shown) by driving to the water supply port (9) through the pipes (23) and (22).

The operation of this example will be described below. Open the outlet (24) for the cement milk mixed by the rotation of the stirring blade (7) in the stirring tank and take out the whole amount as one batch, and then close the outlet (24), and then the motor (11). When the engine is started, the rotation is transmitted to the stirring shaft (6) via the pulley (13), the belt (15) and the pulley (14), so that the sprinkler blade (16) and the receiving plate (17) are connected to the stirring blade (7). It is rotated at the same speed, and at the same time, by starting the pump (21), water is supplied into the guide mass (18) through the pipe (22) and the water supply port (9), and is rotated from the outlet (19). It is made to flow down on the sprinkler blade (16) and the receiving plate (17). The water that has flowed down is temporarily held by the receiving plate (17) and is diffused by the sprinkling blades (16) onto the entire lower surface of the tank upper plate (2) and the inner peripheral surface of the upper part of the tank body (1), and adheres to that portion. Rinse away cement milk, etc., and then flow down to the bottom inner surface and bottom surface of the tank body (1) to wash that part as well. Then, after a short time, a predetermined amount of cement is put into the tank through the chute (10) and the supply port (8), and the kneading with the water used for the washing is started. After supplying the specified amount of water into the tank, stop the pump (21), perform the required kneading, and then take out the whole amount of cement milk from the outlet (24). Kneading is repeated for 1 batch, and the tank is automatically cleaned together with water supply for each batch of work.

As another example of the water guide path to the sprinkler vane (16) in the above example, a guide pipe is connected to the inner end of the water supply port (9), and the tip of the guide pipe is connected to the sprinkler vane (16). ), Which has an opening above it, and other various structures are used.

As another embodiment, the one in which the receiving plate (17) of the sprinkler vane (16) in the above example is removed can be obtained. In that case, the number of blades may be increased, the inclination of the vertical cross section of the blades may be further strengthened, and further, a speed increasing mechanism may be provided to make the rotation speed of the sprinkling blades higher than that of the stirring shaft (6).

[Effect of the device]

 According to the in-tank cleaning device of the agitation tank of the present invention, when the agitation shaft is rotated while supplying water used for kneading the materials into the tank, the upper surface inside the tank is automatically cleaned with the water. Therefore, if one batch of agitation is repeated several times a day in one agitation tank, each time one batch of agitation is carried out, the washing is repeated with the water, so that the deposits on the top surface of the tank in particular solidify. It can be washed off and kept clean. Even if cleaning is performed after the completion of the stirring work for one day, the work can be easily performed in a short time.
