Abstract

The invention discloses a feeding hopper, which comprises a hopper, and the hopper is communicated with a flexible pipeline. The feeding hopper of the present invention is not easy to be blocked by the powder, so no specialized personnel are needed to dredge the pipeline, which saves labor. And the structure is simple, and the implementation cost is low.

Description

a hopper

technical field

The present invention relates to a feeding hopper, more specifically, to a feeding hopper installed on an esterification kettle.

Background technique

The esterification kettle, as the name implies, is the equipment for the esterification reaction, which belongs to the stirring equipment. Structurally, the esterification kettle mainly includes a kettle body, a stirring device arranged in the kettle body and a feed hopper arranged at one end of the kettle body. The structure of the kettle body is usually a vertical cylinder, and its height-to-diameter ratio is mainly determined by the operation, the height-to-diameter ratio of the liquid in the container, and the filling coefficient. The shape of the bottom of the kettle is flat bottom, oval bottom, conical bottom, etc. Sometimes a square kettle can also be used.

There is a feeding hopper on the upper end of the kettle body. The feeding hopper generally includes a hopper with a large opening, and a pipeline connected to the lower end of the hopper and the hopper. During the process of feeding a large amount of material to the hopper, the pipeline is often blocked by powder. Live situations happen. When the pipeline is blocked, someone needs to knock the pipeline to make the powder fall smoothly, which makes the feeding hopper very inconvenient and wastes labor.

Contents of the invention

Aiming at the deficiencies in the prior art, the present invention provides a feeding hopper in which the powder is not easy to block the pipeline.

The present invention is achieved through the following technical solutions: a feeding hopper, comprising a hopper, and the hopper is communicated with a flexible pipe.

In the above technical solution, preferably, the flexible pipe is a cloth cover.

In the above technical solution, elastic support strips are arranged inside the cloth cover.

Compared with the prior art, the present invention has the following beneficial effects: the feeding hopper is not easy to be blocked by the powder material, and therefore no specialized personnel are needed to dredge the pipeline, which saves labor. And the structure is simple, and the implementation cost is low.

Figure 3 is a schematic structural view of Embodiment 2 of the present invention.

Detailed ways

The present invention is described in further detail below in conjunction with accompanying drawing and specific embodiment: Embodiment 1: Referring to Fig. 1, a kind of feeding hopper comprises a hopper 1 with larger opening, is provided with a flexible pipe 2 at the lower end of described hopper 1, More preferably, the flexible pipe 2 is a cloth cover, because the cloth cover has better stretchability, and is very convenient for installation and replacement, and is convenient for maintenance.

Fig. 2 is a schematic diagram of the present invention installed in the esterification kettle, and the feeding hopper is installed on the body of the esterification kettle at this time. When the esterification kettle is in use, a large amount of ester powder needs to be added into the kettle body. At this time, a large amount of ester powder needs to be poured into the hopper 1, and the ester powder enters the kettle body through a pipeline. Ordinary pipelines are rigid pipelines, which can easily cause ester powder to block in the pipeline; the pipeline of the present invention adopts flexible pipelines, and it is difficult for ester powders to accumulate between the pipe walls of the flexible pipelines. Therefore, there will be no problem of clogging the pipe.

The lower end of the hopper 1 is also provided with a stay cord 7, and the stay cord 7 is bound with a plurality of connecting rods 9, the two ends of the connecting rod 9 are provided with spheres 12, and the lower end of the stay cord 7 is provided with four A piece of elastic piece 11 (only two pieces are shown in the figure, and the shapes of the four pieces of elastic pieces are different, so that the pull cord shakes randomly, and the working principle will be described in detail below). The elastic sheet 11 has a curved portion 110, and when the lower end of the pull cord 7 moves to the esterification kettle, the curved portion 110 just touches the esterification kettle, so that the pull rope 7 continuously shakes in the horizontal direction. When stay cord 7 rocked, the spheroid 12 at two ends of connecting rod 9 was stopped to stop the impact cloth cover, preventing ester powder from gathering mutually between the cloth cover inner walls.

To sum up, the feeding hopper is not easy to be blocked by the powder, so there is no need for specialized personnel to dredge the pipeline, which saves labor. And the structure is simple, and the implementation cost is low.

Embodiment 2: See Figure 3. Compared with Embodiment 1, the difference is that an elastic support bar 5 is arranged inside the cloth cover. When the elastic support bar 5 is pressed, it can be deformed. When the external force is canceled, the cloth can be made The sleeve elongates rapidly in the vertical direction, creating a dithering effect. A further step is to prevent the ester powder from accumulating in the cloth cover.
