Description

Technical Field

[0001] The utility model relates to the field of feed processing equipment, in particular to a feeding port of a belt drying machine. Background Art

[0002] The belt dryer is a device that forms the granules made in the granulator through high-temperature drying. Its feed port is set at the top of the equipment. The continuously falling granules are moved through the drying area by the conveyor belt to complete the drying. The high-temperature dry airflow in the dryer is the key to achieve drying. However, since the feed port is set at the top of the equipment and has an opening at the top, hot air will overflow from the feed port, which not only reduces the temperature in the dryer, but also causes the temperature in the processing environment to rise.

[0003] Existing equipment will use an openable cover plate at the feed port, which is opened when feeding and closed at other times. However, this method is not suitable for continuous feeding production. There is also a method of directly sealing the feed port and the conveying end of the granulator together, but this method does not essentially solve the problem of hot air overflow. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the above technology at least to a certain extent. To this end, the purpose of the utility model is to provide a belt dryer feed port to reduce the overflow of hot air.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the utility model proposes a belt dryer feed port, comprising:

[0006] Barrel: rectangular cross section, set at the top of the dryer, with a falling channel formed inside for particles to fall;

[0007] Top plate: arched, hinged to the barrel body at the top of the arch, so that the top plate can swing around the top;

[0008] Baffle: It is arranged in the barrel body below the top plate, and is inclined relative to the horizontal plane to form an inclined plane. The high part of the inclined plane is connected to the barrel body, and a gap is left between the low part and the barrel body for materials to pass through. The orthographic projection area of ​​the baffle is not less than 50% of the cross-sectional area of ​​the falling channel; the baffles are staggered along the direction of the falling channel, and when the material falls, it contacts the low baffle from the high baffle in turn.

[0009] According to the feeding port of the belt dryer of the embodiment of the utility model, the top plate and the baffle plate in the barrel body will not hinder the falling path of the material, and the rising and overflowing hot air flow will be blocked, thereby reducing the rising and overflowing speed and the total amount of overflow.

[0010] In addition, the belt dryer feed port according to the above embodiment of the utility model may also have the following additional technical features:

[0011] Optionally, two opposite sides of the top of the barrel body protrude outward, so that a channel in a corresponding area inside the barrel body forms a giving way structure for the top plate to swing.

[0012] Optionally, the lower part of the baffle is bent downward to form an arc-shaped bending section.

[0013] Optionally, the angle between the baffle and the horizontal plane is between 30° and 50°.

[0014] Optionally, the number of baffles is at least 4.

[0015] Optionally, the upper part of the baffle is hinged to the barrel body so that the baffle can be flipped upwards. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The top plate and the baffle plate in the barrel body of the utility model will not hinder the falling path of the materials, while the rising and overflowing hot air flow will be blocked, thereby reducing the rising and overflowing speed and the total amount of overflow.

[0025] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] As mentioned in the background technology, the existing dryer will have hot air overflowing from the feed port when feeding continuously. In addition to increasing the temperature of the operating area and making the operators uncomfortable, the hot air also overflows with odor and dust. The key to controlling these problems lies in controlling the overflow speed of the hot air flow in the dryer.

[0028] In view of the above problems, the utility model sets a structure on the feed port of the dryer that can reduce the speed of the hot air flow overflowing upwards. The utility model is suitable for a belt dryer with top feeding. This type of dryer has one or more conveyor belts inside to pass the materials through the baking area in sequence. The baking time is often relatively long, so the feeding is required to be continuous and uniform, but not too much. The structure of the utility model helps to uniformly feed the materials to a certain extent.

[0029] Figure 1 to Figure 2 A belt drying machine 100 according to an embodiment of the utility model includes:

[0030] Barrel body 1: rectangular cross section, arranged at the top of the dryer 100, forming a falling channel inside for particles to fall; barrel body 1 is made of stainless steel, and the seams are required to be at the corners of the rectangle. In order to strengthen barrel body 1 to resist deformation caused by impact of materials during material falling, vertical reinforcement strips can also be added to the outside of barrel body 1. The reinforcement strips are L-shaped sections similar to angle steel. The existing feed inlet does not have this reinforcement measure because the material passes vertically, and most of them are ordinary metal straight cylinders.

[0031] Top plate 2: It is arched and hinged to barrel body 1 at the apex of the arch so that top plate 2 can swing around the apex; the structure of top plate 2 is similar to a seesaw structure, with a larger gap when swinging, but as mentioned above, the use scenario of the utility model is continuous feeding. Compared with large-scale feeding, less material passes through per unit time. Most of the time, top plate 2 does not need to swing significantly, and the material can fall into the channel below through the gap between it and barrel body 1. The role of top plate 2 is more to block the rising airflow in the channel.

[0032] Baffle 3: It is arranged in the barrel body 1 below the top plate 2, and is inclined relative to the horizontal plane to form an inclined plane. The upper part of the inclined plane is connected to the barrel body 1, and a gap is left between the lower part and the barrel body 1 for the material to pass through. The orthographic projection area of ​​the baffle 3 is not less than 50% of the cross-sectional area of ​​the falling channel; the baffles 3 are arranged in an interlaced manner along the falling channel. When the material falls, it contacts the lower baffle 3 from the higher baffle 3 in turn. From the side, its moving trajectory is similar to an S shape. The purpose of the baffle 3 is to block the airflow. Overall, its structure is similar to a one-way deceleration valve, which blocks the airflow from the inside of the dryer 100 to the outside.

[0033] The inclined surface of the baffle 3 can be an inclined surface inclined in only one direction, or an inclined surface inclined in two directions, or even a saddle-shaped hyperbolic inclined surface. However, in any case, its structure still serves the purpose of causing materials to fall and blocking the rising airflow.

[0034] In some embodiments, the two opposite sides of the top of the barrel body 1 protrude outward, so that the channel in the corresponding area of ​​the barrel body 1 forms a give way structure for the top plate 2 to swing. The purpose of this is to make the top plate 2 larger, or to obtain the same falling channel area by swinging the top plate 2 with a smaller amplitude while keeping the outlet cross-section unchanged, because each swing of the top plate 2 will also push out a portion of the hot air flow, the greater the swing, the more is pushed out, so reducing the swing amplitude helps to improve the efficiency of the present invention.

[0035] In some embodiments, the lower part of the baffle 3 is bent downward to form an arc-shaped bending section 31. This design makes the falling trajectory of the material fall more downward. Since the material will contact the baffle 3 and generate noise, reducing the time the material contacts the baffle 3 is a goal. The bending section 31 can get closer to this goal and better block the rising hot air flow.

[0036] In some embodiments, the angle between the baffle 3 and the horizontal plane is between 30° and 50°. Within this angle range, a balance can be found between the overall size, the material falling rate, and the airflow blocking effect. Usually, the preferred angle is 45°.

[0037] In some embodiments, at least four baffles 3 are provided. If there are too few baffles, the effect of blocking hot air is reduced, and if there are too many baffles, the manufacturing cost is increased, the path for the material to fall is longer, and the noise is greater.

[0038] In some embodiments, the baffle 3 is hinged to the barrel body 1 at a high point so that the baffle 3 can be flipped up. This structure is convenient for maintenance: by flipping up all the baffles 3, the channel can be completely exposed, which is not much different from an ordinary feed port. This structure can be achieved through a simple hinge, or its position can be limited by the raised limit piece set on the side wall.
