Description

Technical Field

[0001] The utility model relates to the technical field of cement processing, in particular to a building cement powder screening device. Background Art

[0002] During the processing and production of cement, the cement processing plant needs to screen the limestone powder, the raw material of cement, after grinding, to remove the large particles so that it can be more effectively integrated with other mixed materials in the later process.

[0003] The existing construction cement powder screening device has the following main disadvantages during use: the utilization rate of the screen is poor. Since the discharge port of cement powder is fixed, the utilization rate of the screen near the discharge port is high when the screen is screening, while the utilization rate of the screen far away from the discharge port is low, which affects the screening efficiency, and the service life of the screen near the discharge port is short. In addition, cement is easily accumulated on the screen, which reduces the impact stress and shear stress of the screen on the material, easily causes blockage, and leads to low screening efficiency of the screen. Therefore, there is room for improvement. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0025] Embodiment 1:

[0026] Combination Figure 1-5 As shown, this embodiment provides a construction cement powder screening device, including: a main body module 100 and a feeding module 200.

[0027] Among them, the main module 100 includes a body 110, elastic legs 120 symmetrically installed on both sides of the body 110, a screen 130 installed on the inner wall of the body 110, a discharge port 140 installed below the body 110, and a vibration motor 150 installed on one side of the body 110.

[0028] The body 110 is used to install other components. The elastic legs 120 support the body 110 and facilitate the vibration of the body 110. The screen 130 is used to screen the cement powder. The discharge port 140 is used to send out the screened cement powder. The vibration motor 150 is used to drive the body 110 to vibrate. The vibration of the body 110 drives the screen 130 to vibrate, thereby realizing vibration screening of the cement powder.

[0029] The feeding module 200 is used to feed cement powder onto the screen 130, and includes a feeding pipe 210 movably arranged above the body 110, a hopper 220 fixed at the top of the feeding pipe 210, rollers 230 symmetrically installed on both sides of the feeding pipe 210, a feeding member 240 installed on the feeding pipe 210 and extending into the inner cavity of the feeding pipe 210, a driving member 250 symmetrically installed on both sides of the body 110, and a connecting plate 260 with one end fixed on the feeding pipe 210 and the other end sleeved on the driving member 250.

[0030] The feed pipe 210 is used to transport cement powder. The hopper 220 is fixed at the top of the feed pipe 210 and is connected to the feed pipe 210 for storing cement powder that needs to be screened. The roller 230 is close to the top of the body 110 to facilitate the movement of the feed pipe 210 and ensure the stability of the feed pipe 210 when moving.

[0031] The feeding member 240 is used to control the material discharge speed of the material discharge tube 210, and includes a rotating shaft 241 rotatably mounted on the inner wall of the material discharge tube 210 at one end, a baffle 242 fixed on the rotating shaft 241 in a circular array, and a first motor 243 mounted on the outer surface of the material discharge tube 210 and fixedly connected to the end of the rotating shaft 241. The rotating shaft 241 is used to install the baffle 242 and drive the baffle 242 to rotate. An arc groove is fanned out on the opposite inner wall of the material discharge tube 210. One end of the baffle 242 is fixed on the rotating shaft 241, and the other end is close to the inner wall of the arc groove. A storage cavity is formed between adjacent baffles 242. When in use, the material in the hopper 220 The cement powder enters the discharge pipe 210 and falls into the storage chamber facing the hopper 220. At this time, the rotating shaft 241 rotates, driving the storage chamber to rotate, so that the storage chamber rotates to the side facing the screen 130. At this time, the cement powder in the discharge chamber falls onto the screen 130 under the action of gravity, thereby realizing the feeding of the cement powder. The first motor 243 is used to drive the rotating shaft 241 to rotate. Controlling the speed of the first motor 243 can control the rotation speed of the rotating shaft 241, that is, controlling the rotation speed of the baffle 242, thereby realizing the discharge speed control of the discharge pipe 210, and avoiding the phenomenon that the cement powder is discharged too quickly and accumulates on the screen 130.

[0032] The driving member 250 is used to drive the discharge pipe 210 to move, including a threaded rod 251 rotatably installed on one side of the machine body 110 and a second motor 252 installed on the machine body 110 and fixedly connected to the end of the threaded rod 251. Bearing seats are symmetrically installed on both sides of the machine body 110, and both ends of the threaded rod 251 are installed on the bearing seats to maintain the stability of the threaded rod 251 and facilitate the rotation of the threaded rod 251. The shaft of the second motor 252 is fixedly connected to the end of the threaded rod 251, and is used to drive the threaded rod 251 to rotate.

[0033] One end of the connecting plate 260 is fixed on the outer surface of the discharge pipe 210, and the other end is provided with a threaded hole 261. The threaded rod 251 passes through the threaded hole 261 and engages with the threaded hole 261. When the threaded rod 251 rotates in the threaded hole 261, it can drive the connecting plate 260 to move, and the movement of the connecting plate 260 drives the discharge pipe 210 to move.

[0034] The working principle and use process of the utility model are as follows: when in use, the cement powder to be screened is poured into the hopper 220, and the vibration motor 150 is started. The vibration of the vibration motor 150 drives the screen 130 to vibrate through the body 110. At this time, the cement powder in the hopper 220 enters the discharge pipe 210 and falls between the adjacent baffles 242. The first motor 243 is started to drive the rotating shaft 241 to rotate. The rotation of the rotating shaft 241 drives the baffle 242 to rotate, so that the adjacent baffles The cement powder between 242 rotates to the bottom and is sent out through the discharge pipe 210, and falls onto the screen 130 for screening. At the same time, the second motor 252 is started, driving the threaded rod 251 to rotate, and the rotation of the threaded rod 251 drives the connecting plate 260 to move, and the movement of the connecting plate 260 drives the discharge pipe 210 to move, so that the discharge pipe 210 moves back and forth on the machine body 110, so that the cement powder can be evenly spread on the surface of the screen 130, thereby increasing the utilization rate of the screen 130.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
