Description

A feed hopper for a dryer

(1) Technical field

The utility model relates to the field of plastic production machinery, in particular to a feed hopper for a dryer.

(2) Background technology

Plastic dryers are commonly used equipment in the plastic processing industry, but traditional plastic dryers have many shortcomings. The air enters the chassis directly from the exhaust fan, and there is generally only one drying pipe at present, resulting in poor effect. The hot air after work is directly discharged from the air The pipe is exhausted into the workshop, so that the hot air is directly discharged into the workshop, resulting in heat loss. At the same time, the air sucked by the exhaust fan contains dust and is discharged into the workshop, which affects the health of workers. At the same time, these impurities will enter the plastic molding machine together with the plastic, seriously Affects plastic quality.

Plastic granules are a semi-finished product formed after plastic strips are drawn, cooled and cut. Since the plastic granules still have moisture attached to them after being water-cooled, they need to enter the dryer for drying work, because when the plastic granules contain moisture, it is easy to produce air bubbles. , moiré, crack spots, cracking and hydrolysis, etc. At present, more and more simple plastic granules are used to remove water by heating and dehumidifying methods to remove moisture in plastics. This drying machine is called a plastic dryer. At present, the feeding of the plastic dryer in the prior art often uses several ways to pour the plastic particles into the feed, one of which is to directly pour the plastic particles into the opening of the dryer, but this method is cumbersome. A hopper is used for feeding, but due to the moisture attached to the surface of the undried plastic particles, when the plastic particles are on the hopper, they will stick to the side wall of the hopper and it is difficult to feed. Usually, a scraper is used to scrape the plastic to the surface. The feed inlet may be connected with an external water pipe, and then a person needs to hold the water pipe to send it into the feed inlet through the thrust of the airflow against the plastic particles that have not fallen down. The operation of controlling the air flow direction at the feed port is time-consuming and laborious, and wastes production costs. The way of connecting it with water pipes increases the working intensity of the dryer. At the same time, the drying process can only be carried out in a drying container, and the drying efficiency is relatively low.

(3) Contents of the invention

In order to make up for the defects of the prior art, the utility model provides a feed hopper for a dryer which is not hung on the wall, is easy to clean and has high heating efficiency.

The utility model is achieved through the following technical solutions:

A feed hopper for a dryer, comprising a body, characterized in that a motor is provided at the upper end of the body, the output end of the motor faces downward and is connected to an auger, the auger is located in the body, and the body It is a hollow structure, and there are several elongated holes from the upper end of the body to the lower end on the inner wall of the body. There are several rotating shafts in the cavity of the body, and the rotating shafts protrude from the elongated holes and are connected with the elongated The inner wall of the body on both sides of the shaped hole is in contact; an air-filled tube is fixed between two adjacent elongated holes, and the upper ends of all the air-filled tubes are connected in parallel to the heating pipe and fan arranged outside the body in sequence. , each of the inflatable tubes is provided with a plurality of inflatable branch pipes, the opening of the inflatable branch pipes is downward, and a filter is provided at the opening end of the inflatable branch pipes.

The diameter of the auger is larger at the top and smaller at the bottom.

The body is rounded and truncated.

The beneficial effects of the utility model are:

The stirring device designed by the utility model keeps the plastic particles in a state of continuous flow, which not only prevents the blockage of the plastic particles, but also accelerates the falling speed of the plastic particles and improves the work efficiency. The scraping between the shaft and the inner wall of the main body will scrape off the plastic particles adsorbed on the inner wall of the main body, and at the same time, the hot air introduced from the inflatable tube will help to blow off the plastic particles adsorbed on the inner wall of the main body, which is conducive to the flow of plastic particles It is easy to clean the inner wall of the main body, and on the other hand, it also helps to initially heat the plastic pellets and improve the drying efficiency.

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is a schematic cross-sectional structure diagram of the utility model.

Among the figure, 1 body, 2 motors, 3 screw augers, 4 rotating shafts, 5 elongated holes, 6 inflatable pipes, 7 inflatable branch pipes, 8 blower fans, 9 heating pipes, and 10 filter screens.

(5) Specific implementation methods

Accompanying drawing is the specific embodiment of the utility model. As shown in Figure 1, the feed hopper for this type of dryer includes a rounded truncated body 1, a motor 2 is installed on the upper end of the body 1, the output end of the motor 2 faces downward and is connected to the screw auger 3, the screw auger 3 is located in the body 1, the diameter of the helical sheet on the screw auger 3 is large and small; the body 1 is a hollow structure, and there are a number of elongated holes 5 from the upper end to the lower end of the body 1 on the inner wall of the body 1. There are several rotating shafts 4 in the cavity of 1, the number of rotating shafts 4 is the same as the number of elongated holes 5, (the elongated holes 5 in the figure are also rotating shafts 4, and their positions coincide) and correspond one by one, Each rotating shaft 4 protrudes from the corresponding elongated hole 5 and contacts the inner wall of the body 1 on both sides of the elongated hole 5. When the motor 2 is started, the rotation of the auger 3 drives the plastic particles to rotate, and the rotation The shaft 4 rotates freely under the drive of the plastic particles. When the rotating shaft 4 rotates, the inner wall of the body 1 scrapes the rotating shaft 4; There are inflatable tubes 6, and all the inflatable tubes 6 are connected in parallel with the heating tube 9 and the fan 8 arranged outside the body 1 in sequence. Each inflatable tube 6 is provided with a number of inflatable branch pipes 7, and the opening of the inflatable branch pipes 7 is downward. In addition, a filter screen 10 is installed at the opening end of the inflatable branch pipe 7, and the air coming out of the fan 8 is heated by the heating pipe 9 and then blown out from the inflatable branch pipe 7, which not only preliminarily dries the plastic particles, but also adsorbs them on the inner wall of the body 1. The plastic particles on the surface are blown away and fall down, which improves the feeding efficiency and prevents the plastic particles from being adsorbed on the inner wall of the body 1. At the same time, the plastic particles are initially dried, which is a guarantee for the drying of the plastic particles in the dryer. Adequate preparation will help improve drying efficiency.
