Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a feed inlet structure of talcum powder grinding equipment. Background Art

[0002] Talc is a white or off-white, fine, non-gritty powder that feels greasy to the touch. It is odorless and tasteless. It is insoluble in water, dilute mineral acid or dilute alkali hydroxide solution.

[0003] According to demand, talcum powder needs to be ground during the production process. The coarse talcum powder needs to be de-ironized before entering the grinding equipment to avoid entering the grinding equipment and causing damage to it, which may also affect the production quality of talcum powder.

[0004] Although there is iron removal treatment at the workstation before grinding, there are cases where the cleaning is not thorough or iron impurities are mixed in during the process. In order to ensure that the talc coarse material entering the grinding equipment does not contain iron as much as possible, some existing grinding equipment has an iron removal structure installed on the feed port. The feed port of the grinding equipment is generally in the shape of a square funnel. The existing method is to insert multiple magnet bars horizontally into the funnel to adsorb the iron impurities in the material and then treat them uniformly.

[0005] However, in the above-mentioned prior art, since the talcum powder coarse material is directly put into the funnel, under the influence of gravity, most of the material falls directly from the center of the hopper at a fast speed. The iron impurities in the talcum powder coarse material are difficult to be directly adsorbed by the magnet bar, and the effect is poor. In addition, when cleaning, personnel can only pick off the iron impurities on the magnet bar with their bare hands, and there is a situation where the iron blocks cannot be grasped and fall directly into the grinding equipment, making cleaning difficult. Utility Model Content

[0006] In view of the above-mentioned deficiencies in the prior art, the utility model provides a feed inlet structure of a talcum powder grinding equipment, in which a guide plate is installed at the center position in the hopper, and the guide plate guides the material to the side wall of the hopper. The talcum powder is decelerated by the blocking deceleration of the guide plate and the friction deceleration of the side wall of the hopper, so that its speed is slowed down when passing through the magnet bar, thereby ensuring that the iron impurities can be adsorbed by the magnet bar, thereby improving the iron removal effect.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a feed inlet structure of talcum powder grinding equipment, including a square funnel-shaped hopper, a guide plate with a high center and low surroundings, four mounting plates and multiple fixed rods, the lower part of the hopper is respectively provided with openings, the four mounting plates can be respectively blocked or opened and set on the openings, a plurality of magnet bars are evenly arranged on the inner side wall of each mounting plate, the plurality of magnet bars are horizontally arranged and flush with the inner side wall of the mounting plate, the guide plate is mounted inside the hopper by a plurality of fixed rods, and the height and inclination angle of the guide plate are sufficient to slide the material to the upper part of the hopper side wall.

[0008] Preferably, the lower end of the mounting plate is rotatably connected to the lower edge of the opening via a rotating shaft, and a clamping plate is rotatably provided on the side wall of the hopper corresponding to the upper edge of the opening. When the mounting plate is rotated to block the opening, the rotating clamping plate can fix the mounting plate.

[0009] Preferably, a sealing gasket is provided on the end surface of the mounting plate.

[0010] Preferably, a handle is provided on the outer side wall of the mounting plate.

[0011] Preferably, the outer side wall of the hopper and the outer side wall of the hopper bottom are provided with reinforcing rods.

[0012] The utility model provides a feed inlet structure of a talcum powder grinding device, which has the following beneficial effects:

[0013] 1. The utility model sets up a guide plate at the center of the hopper, which guides the material to the side wall of the hopper. The talcum powder is decelerated by the guide plate and the friction of the side wall of the hopper, so that the speed of the talcum powder passing through the magnet bar is slowed down, thereby ensuring that the iron impurities can be adsorbed by the magnet bar, and improving the iron removal effect;

[0014] 2. In the utility model, the mounting plate is rotatably connected to the lower edge of the hopper opening, and a clamping plate on the outer wall of the hopper near the upper edge of the opening is used as a lock for the mounting plate, which is easy to open and close. When opening, an external scraper can be used to clean the side of the mounting plate corresponding to the magnet bar, which is convenient and efficient to clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-3 As shown, a feed inlet structure of a talcum powder grinding device comprises a square funnel-shaped hopper 1, a guide plate 6 with a high center and low surroundings, four mounting plates 3 and a plurality of fixing rods 7, the lower part of the hopper 1 is respectively provided with openings 2, the four mounting plates 3 can be respectively blocked or opened and arranged on the openings 2, a plurality of magnet bars 5 are evenly arranged on the inner side wall of each mounting plate 3, the plurality of magnet bars 5 are horizontally arranged and flush with the inner side wall of the mounting plate 3, the guide plate 6 is erected in the hopper 1 through a plurality of fixing rods 7 The height and inclination angle of the guide plate 6 are sufficient to slide the material to the upper part of the side wall of the hopper 1; the lower end of the mounting plate 3 is rotatably connected to the lower edge of the opening 2 through the rotating shaft 4, and a clamping plate 8 is rotatably provided on the side wall of the hopper 1 and corresponding to the upper edge of the opening 2. When the mounting plate 3 is rotated to block the opening 2, the rotating clamping plate 8 can fix the mounting plate 3; a sealing gasket 11 is provided on the end face of the mounting plate 3; a handle 9 is provided on the outer side wall of the mounting plate 3; a reinforcing rod 10 is provided on the outer side wall of the hopper 1 and the outer side wall of the bottom of the hopper 1.

[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the instruction manual Figure 1-3 It can be seen that when the utility model is working, talcum powder coarse material is injected into the hopper 1 from the top of the hopper 1, and the falling material falls on the guide plate 6, which can be understood as the material being blocked and decelerated. Since the height and inclination angle of the guide plate 6 are sufficient to slide the material to the upper part of the side wall of the hopper 1, specifically, the lowest point of the guide plate 6 must be higher than the upper edge of the material opening 2, and its inclination angle can make the sliding material hit the upper part of the side wall of the hopper 1. Since the hopper 1 is a square funnel shape, the side wall is an inclined surface, and the material can slide down from the side wall of the hopper 1. Due to the openings around the side wall of the hopper 1 2 is provided with a mounting plate 3, and the mounting plate 3 is provided with a plurality of magnet bars 5, therefore, the material sliding down from the side wall of the hopper 1 can slide down from the mounting plate 3 and the magnet bars 5, the magnet bars 5 can adsorb the iron impurities, and the material continues to pass through and enter the grinding equipment, in this process, because the plurality of magnet bars 5 are arranged horizontally and are flush with the inner side wall of the mounting plate 3, therefore, the magnet bars 5 will not affect the passage of the material, and at the same time, because the guide plate 6 is connected to the hopper 1 by a fixed rod 7, there is enough gap between the guide plate 6 and the hopper 1 to allow the material to pass through, and the material feeding speed will not be affected. In the utility model, the talcum powder coarse material is decelerated by the friction deceleration of the guide plate 6 and the side wall of the hopper 1, so that the speed when it passes through the magnet bars 5 is slowed down, thereby ensuring that the iron impurities can be adsorbed by the magnet bars 5, and the speed of falling directly by gravity relative to the prior art will be much smaller, thereby improving the iron removal effect. In addition, the overall structure of the utility model is relatively simple, and commonly used parts are used, but the iron removal effect achieved will be better than the prior art.

[0023] Among them, the lower end of the mounting plate 3 is rotatably connected with the lower edge of the opening 2 through the rotating shaft 4, and a clamping plate 8 is rotatably provided on the side wall of the hopper 1 and corresponding to the upper edge of the opening 2. The mounting plate 3 can be rotated by the rotating shaft 4 to block the opening 2. At this time, the mounting plate 3 can be locked by rotating the clamping plate 8 to be in a closed state. At this time, the inner wall of the mounting plate 3 and the magnet plate on the mounting plate 3 are flush with the inner wall of the hopper 1. Multiple clamping plates 8 can also be provided here to ensure the stability of the mounting plate 3. When opening, the clamping plate 8 can be rotated again to open the mounting plate 3, and the magnet bar 5 and the iron impurities adsorbed by it are exposed outside the hopper 1. Personnel can clean the iron impurities through external scrapers and other components. Cleaning is convenient and efficient, and it is easy to repair and maintain.

[0024] Among them, the end face of the mounting plate 3 is provided with a sealing pad 11 to ensure that the material will not pass through the gap between the mounting plate 3 and the hopper 1 during operation. In addition, a handle 9 can also be provided on the outer side wall of the mounting plate 3 to facilitate personnel to open and close the mounting plate 3.

[0025] Among them, reinforcing rods 10 are provided on the outer side wall of the hopper 1 and the outer side wall of the bottom of the hopper 1 to increase the overall stability of the hopper 1.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
