Description

Technical Field

[0001] The utility model relates to the field of vibration screen equipment, in particular to a material receiving port of a vibration screen. Background Art

[0002] Under normal circumstances, the material output port and the material conveying direction of the vibrating screen form a straight line. The edge of the output port is generally set up in the width direction of the vibrating screen, so that the material falls along the width direction of the vibrating screen. For example, the dryer and the vibrating screen form a straight line and are produced on the same production line, so that the material is evenly distributed in the width direction of the vibrating screen. However, in some application scenarios, such as being restricted by the space problem of the production workshop, the drying room and the vibrating screen cannot be on the same line, and the dryer and the vibrating screen can only be connected at right angles. The dryer is located in the width direction of the vibrating screen instead of the traditional length direction. This form causes the material coming out of the output port to be output in a straight line and fall into the middle position of the width direction of the vibrating screen along the length direction of the vibrating screen. The material in the width direction of the vibrating screen is uneven, causing the material to fall to the middle position of the vibrating screen and the material thickness is too high, so the air cannot blow through, resulting in high material temperature and high moisture content.

[0003] Therefore, there is an urgent need for a vibrating screen receiving port suitable for materials to fall into the middle position in the width direction of the vibrating screen. Utility Model Content

[0004] The utility model aims to provide a vibrating screen receiving port suitable for materials concentrated in the middle position in the width direction of the vibrating screen and falling into the material receiving port.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A vibrating screen receiving port comprises a supporting plate fixed above an input end of the vibrating screen;

[0007] The support plate includes a plate-shaped bottom plate and baffles surrounding three edges of the bottom plate, wherein the baffles include a pair of oppositely arranged side baffles and a main baffle located between the two side baffles;

[0008] The two side baffles are respectively arranged on both sides of the vibrating screen in the width direction, and the main baffle is arranged on one side in the length direction of the vibrating screen;

[0009] The materials concentrated in the middle of the width direction of the vibrating screen are temporarily stored on the support plate when they fall down. When the support plate and the vibrating screen vibrate synchronously, the materials temporarily stored on the support plate can be vibrated to the input end of the vibrating screen through the edge of the main baffle.

[0010] Furthermore, the baffle plate also includes a secondary baffle plate arranged opposite to the main baffle plate, and the baffle plate surrounds the four sides of the chassis.

[0011] Furthermore, it also includes a centralized cover, wherein an output port for conveying materials to the vibrating screen is placed above one side in the width direction of the vibrating screen, and the centralized cover is used to cover the output port and the support plate.

[0012] Further, one end of the concentrating cover can be fixed to the output port, and the other end of the flexible concentrating cover is tilted downward and can be fixed to a side of the vibrating screen away from the output port in the width direction.

[0013] Furthermore, the central cover is made of cloth.

[0014] In the above technical solution, the utility model has the following beneficial effects:

[0015] The pallet keeps the material with thickness temporarily stored on it, and the side baffle plays the role of piling up the material. These materials are vibrated onto the vibrating screen through the edge of the main baffle to disperse the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] It should be noted that the terms "above", "one end", "upper", etc. used in this article indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Similar expressions are only for the purpose of illustration, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] like Figure 1-3 A vibrating screen receiving port is shown, which includes a support plate 1 fixed above the input end of a vibrating screen 2, so that the support plate 1 and the vibrating screen 2 can vibrate synchronously. The function of the support plate 1 is to receive the material concentrated in the middle position of the width direction of the vibrating screen 3, and then disperse the material in the width direction of the vibrating screen 2 and vibrate the material to the input end of the vibrating screen 2. The vibrating screen 2 is preferably a linear vibrating screen. The material is transmitted from front to back on the vibrating screen 2.

[0025] Specifically, the support plate 1 includes a plate-shaped chassis 11 and baffles surrounding the three side edges of the chassis 11, and the baffles include a pair of side baffles 31 arranged opposite to each other and a main baffle 32 fixed between the two side baffles 31. The baffles surround the chassis 11 so that the materials can be temporarily stored on the chassis 11. The chassis 11 is preferably a rectangular flat plate, and the baffles are U-shaped as a whole. The width of the chassis 11 is not greater than the width of the vibrating screen. The baffles are sheet-shaped and can be perpendicular to the chassis 11.

[0026] The two side baffles 31 are respectively arranged on both sides of the width direction of the vibrating screen 2, and the main baffle 32 is arranged on one side in the length direction of the vibrating screen 2, that is, no baffle may be arranged in front of the chassis 11. The side baffles 31 mainly play the role of blocking the material, so that the material is concentrated on the vibrating chassis so that the material will have a certain thickness on the chassis. The main baffle 32 is located above the input end, and its main function is to disperse and convey the material. The input end of the vibrating screen receives the material on the main baffle 32. The height of the main baffle 32 can be different from the height of the two side baffles 31, and the height of the main baffle 32 is not greater than the height of the two side baffles 31. The chassis can be tilted downward from the front to the back by no more than 5°, which is conducive to the main baffle 32 to drop the material.

[0027] Because the pallet 1 temporarily stores the materials concentrated in the middle of the width direction of the vibrating screen 2 on the pallet 1 when they fall, the pallet 1 and the vibrating screen 2 can vibrate the materials temporarily stored on the pallet 1 to the input end of the vibrating screen 2 through the edge of the main baffle 32 when the pallet 1 and the vibrating screen 2 vibrate synchronously. In this way, the materials are dispersed in the width direction of the vibrating screen 2.

[0028] When the length of the chassis 11 is long enough, the material is far away from the side of the chassis where the baffle is not provided, and the material will not escape, so an opening on one side can be left in front of the baffle. Preferably, the baffle also includes a secondary baffle arranged opposite to the main baffle 32, and the baffle surrounds the chassis 111. This ensures that the material is concentrated on the chassis and shortens the length of the chassis. The direction from the secondary baffle to the main baffle 32 is the conveying direction of the material on the vibrating screen 2.

[0029] By changing the pallet that comes with the material receiving port of the vibrating screen, the original pallet that comes with the vibrating screen equipment is a rectangular hollow stainless steel plate. Now a 1 cm high edge is added to the length side and the width sides of the pallet to form a baffle, and the bottom of the pallet is hollowed out and blocked. In this way, the material needs to be temporarily stored at a thickness of about 1 cm when falling into the input end of the vibrating screen, and then it is vibrated evenly in parallel according to the frequency of the vibrating screen, so that the material is spread on the entire vibrating screen, and the original accumulation on the screen may be 3 cm thick. Change to 0.5 cm, and then use the blowing heat dissipation of the vibrating screen to make the material temperature and moisture reach the standard range.

[0030] In order to solve the problem of dust flying from the material on the support plate, a centralized cover 3 is added to the material receiving port of the vibrating screen, and the output port for conveying materials to the vibrating screen 2 is placed above one side in the width direction of the vibrating screen 2, and the centralized cover 3 is used to cover the output port and the support plate 1. In this way, the material conveying space between the output port and the support plate 1 is limited, and the material will not fly into the room. The centralized cover 3 is preferably fixed to the output port.

[0031] Preferably, one end of the centralizing cover 3 can be fixed to the outlet, and the other end of the centralizing cover 3 is tilted downward and can be fixed to the side of the vibrating screen 2 away from the outlet in the width direction. Since the vibrating screen 2 vibrates and its position will move, the centralizing cover needs to be flexible to accommodate the vibration of the vibrating screen 2. Optionally, the middle position of the centralizing cover 3 can be fixed to the secondary baffle 34.

[0032] Preferably, the central cover 3 is a cloth product. The cloth product can be tied or pasted to the output port and the support plate 1 by a rope. Figure 1-2 As shown, the dryer feed port 4 of the dryer is placed on the chassis but not in contact with it, and the central cover 3 covers the dryer feed port 4 and the support plate 1, leaving only an opening on one side of the main baffle for easy observation of the material.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
