Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] The following combines the attached Figures 1-4 to further elaborate on the embodiments of the present application.

[0028] Embodiment 1

[0029] Please refer to Figures 1-4 , this embodiment provides a technical solution: a quantitative feeding device, including: a material conveying trough 1 and a feeding and pushing mechanism 2;

[0030] A plurality of groups of holes are equidistantly opened inside the material conveying trough 1. When the powder inside is conveyed to the holes, it is convenient to drive the powder to move into the petrochemical sewage tank below. The feeding and pushing mechanism 2 is arranged on the material conveying trough 1. The feeding and pushing mechanism 2 can store the powder and conveniently drive the powder in the material conveying trough 1 to move stably in the horizontal direction. The feeding and pushing mechanism 2 includes a first discharge pipe 201 welded to the outer wall of the hole of the material conveying trough 1, and a solenoid valve is fixedly arranged inside the first discharge pipe 201. By opening the solenoid valve inside the first discharge pipe 201, the powder in the material conveying trough 1 can be quantitatively conveyed into the petrochemical sewage tank.

[0031] The first block 202 welded to both ends of one side of the outer wall of the material conveying trough 1 can stably fix the inner structure on one side of the outer wall of the material conveying trough 1. The second block 203 welded to both ends of the other side of the outer wall of the material conveying trough 1 can stably fix the inner structure on the other side of the outer wall of the material conveying trough 1. A bearing is fixedly installed inside the second block 203, which can effectively fix the internal structure and does not affect the rotation of the internal structure. The guide rod 204 welded to the first block 202 can stably move the structure on the rod in the horizontal direction. The threaded screw rod 205 installed in the bearing of the second block 203 can stably drive the structure on the rod to rotate during the rotation process. The slider 206 is arranged on the guide rod 204 and the threaded screw rod 205. The slider 206 on the guide rod 204 can stably move in the horizontal direction through the rotation of the threaded screw rod 205. The scraper 207 welded below the slider 206 is connected to the slider 206 and drives the powder on one side to move stably during the synchronous displacement process. The bottom of the scraper 207 is attached to the inner bottom of the material conveying trough 1, which can stably convey the powder inside the material conveying trough 1.

[0032] After the powder is conveyed into the interior of the material conveying trough 1, the threaded screw rod 205 inside the second block 203 rotates, thereby driving the slider 206 on the rod to stably move on the guide rod 204 of the first block 202. At this time, during the movement of the slider 206, it will synchronously drive the scraper 207 connected below to move, thereby driving the powder inside the material conveying trough 1 to move. When the powder moves into one of the first discharge pipes 201, the solenoid valve inside the first discharge pipe 201 is activated. At this time, the powder will be conveyed into the interior of the petrochemical sewage tank, and then the solenoid valve of this first discharge pipe 201 is closed. The powder is driven by the movement of the scraper 207 to move into the other group of first discharge pipes 201, and the above operation is repeated by opening the solenoid valve.

[0033] Embodiment 2

[0034] Please refer to Figures 1-4 , this embodiment provides a technical solution: a quantitative feeding device, including: a motor 208, a first pulley 209, a second pulley 210, a wide belt 211, a storage bin 212 and a second discharge pipe 213;

[0035] A motor 208 is arranged below the outer wall of the material feeding trough 1, and a rotating shaft is connected to the output end of the motor 208. The motor 208 can drive the structure connected to the rotating shaft to rotate synchronously through the rotating shaft on the output end. A first belt pulley 209 is fixedly arranged on the rotating shaft of the motor 208. The first belt pulley 209 can be clamped and fixed to the rotating shaft, so as to rotate stably on the output end of the motor 208. A second belt pulley 210 is arranged on the threaded lead screw 205. A wide belt 211 has one end sleeved on the first belt pulley 209. The second belt pulley 210 is connected to the first belt pulley 209 through the wide belt 211. Thus, during the rotation of the first belt pulley 209, the second belt pulley 210 is driven to rotate.

[0036] A storage bin 212 is arranged above the material feeding trough 1. The storage bin 212 can store the powder material. When the powder material needs to be put in, it can quickly convey the internal powder material. And the storage bin 212 is connected to the material feeding trough 1 through a connecting rod, and can be stably fixed above the material feeding trough 1 through the connecting rod. A second discharge pipe 213 is welded to the bottom of the storage bin 212, and an electromagnetic valve is arranged inside the second discharge pipe 213. Deciding whether to open the electromagnetic valve inside the second discharge pipe 213, so as to provide for the storage of the material in the storage bin 212 and subsequent conveying and putting work.

[0037] By deciding whether to open the electromagnetic valve inside the second discharge pipe 213 below the storage bin 212, it can be determined whether to convey the powder material into the interior of the material feeding trough 1. Start the motor 208, and the motor 208 will drive the first belt pulley 209 connected to the output end to rotate. Because the second belt pulley 210 is connected to the threaded lead screw 205, and the first belt pulley 209 and the second belt pulley 210 are connected through the wide belt 211, at this time, the threaded lead screw 205 connected to the second belt pulley 210 will rotate synchronously.

[0038] The implementation principle of a quantitative feeding device of the present application is as follows:

[0039] First of all, by deciding whether to open the electromagnetic valve inside the second discharge pipe 213 below the storage bin 212, it can be determined whether to convey the powder material into the interior of the material feeding trough 1. After the powder material is conveyed into the interior of the material feeding trough 1, start the motor 208, and the motor 208 will drive the first belt pulley 209 connected to the output end to rotate. Because the second belt pulley 210 is connected to the threaded lead screw 205, and the first belt pulley 209 and the second belt pulley 210 are connected through the wide belt 211, at this time, the threaded lead screw 205 connected to the second belt pulley 210 will rotate synchronously.

[0040] Secondly, the threaded lead screw 205 inside the second block 203 rotates, thereby driving the slider 206 on the rod to move stably on the guide rod 204 of the first block 202. At this time, during the movement of the slider 206, the scraper 207 connected below will be driven to move synchronously, thereby driving the powder in the material conveying trough 1 to move.

[0041] Finally, when the powder moves into one of the first discharge pipes 201, the solenoid valve inside the first discharge pipe 201 is activated. At this time, the powder will be conveyed into the interior of the petrochemical sewage tank, and then the solenoid valve of this first discharge pipe 201 is closed. The powder is driven to move into the other group of first discharge pipes 201 by the movement of the scraper 207, and the above operation is repeated by opening the solenoid valve.

[0042] For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of this application, this application can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of this application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in this application. Any reference signs in the claims should not be regarded as limiting the claims involved.
