[0001] This application relates to the field of cementing material production technology, specifically to a screening device for small-particle cementing materials. Background Technology

[0002] Cementing materials mainly include cement, additives, and chemicals. In cementing operations, cement is the primary cementing material, used to fill the annular space between the wellbore and the casing to support and protect the oil and gas well. In addition, cementing additives and chemicals also play important roles, including setting accelerators, setting retarders, defoamers, drag reducers (dispersants), filtration reducers, gas channeling inhibitors, weight-reducing admixtures, leakage-preventing admixtures, reinforcing agents, and weight-enhancing admixtures.

[0003] Before batching, many cementing materials require screening of some small particles according to different product requirements. Current screening equipment suffers from problems such as poor continuity and easy material blockage. Utility Model Content

[0004] In view of the above problems, embodiments of this application provide a screening device for small-particle cementing materials.

[0005] It is not prone to clogging and can continuously screen small-particle cementing materials with high screening efficiency.

[0006] According to one aspect of the embodiments of this application, a screening device for small-particle cementing materials is provided. The screening equipment for small-particle cementing materials includes a support frame. A screen plate is inclinedly arranged on one side of the top of the support frame, and the screen plate has screen holes. A vibration motor is installed on the support frame, and the vibrating end of the vibration motor abuts against the screen plate. A distribution hopper is connected to the top of the support frame through a fixed frame. A distribution component is provided at the bottom of the distribution hopper. A diversion channel is provided on one side of the support frame below the screen plate. A first conveyor belt is provided at the bottom of the support frame. The end of the diversion channel away from the support frame is inclined downward and extends to the first conveyor belt. A second conveyor belt is provided below the screen plate. The distribution component includes multiple discharge channels connected to the bottom of the distribution hopper and located at the same horizontal level. A disc-shaped diverter is provided at the intersection of the top of the discharge channel and the distribution hopper. A linkage shaft is provided through the distribution hopper. One end of the linkage shaft is connected to a drive motor. The linkage shaft is coaxially connected to multiple disc-shaped diverters. A storage trough is provided on the outer periphery of each disc-shaped diverter.

[0007] In some embodiments, a V-shaped collection bin is fixed on the support frame, the top of the collection bin is open and located below the screen plate, and the bottom of the collection trough is narrowed and extends to the top of the second conveyor belt.

[0008] In some embodiments, a storage bin is included, which is connected to the top of the distributing hopper via a feeding device.

[0009] In some embodiments, a dust collection hood is included, which is fixed to the top of the screen plate. A negative pressure fan is fixed to the top of the distribution hopper. The inlet end of the negative pressure fan is connected to the dust collection hood through a negative pressure pipe, and the outlet end of the negative pressure fan extends into the distribution hopper.

[0010] In some embodiments, the storage tanks on two adjacent disc-shaped drain members are staggered.

[0011] In some embodiments, the disc-shaped drain member is provided with a plurality of storage slots, which are distributed at intervals along the circumference of the disc-shaped drain member.

[0012] The beneficial effects of this application are as follows: By setting up components such as a first conveyor belt and a second conveyor belt, the large and small particles that have been screened can be transferred to the outer periphery of the equipment respectively, enabling the entire screening process to proceed continuously and efficiently. This application also includes a material distribution component, which comprises multiple feeding channels, a disc-shaped guide component, a drive motor, and a linkage shaft.

Detailed Implementation

[0021] The embodiments of the technical solution of this application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and the foregoing description of the accompanying drawings are intended to cover non-exclusive inclusion.

[0022] For details, please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall structure of the small particle cementing material screening equipment provided in the embodiments of this application. Figure 2 This is a partial structural diagram of the device provided in an embodiment of this application. Figure 3 This is a partial structural diagram of the linkage shaft and its connection provided in an embodiment of this application. Figure 4This is a partial cross-sectional structural diagram of the hopper provided in an embodiment of this application. The screening equipment 100 for small-particle cementing materials includes a support frame 110. A screen plate 120 is inclinedly arranged on one side of the top of the support frame 110. Screen holes are formed on the screen plate 120. Raw materials fall from the hopper 130 onto the top of the screen plate 120 and gradually slide down along the inclined direction of the screen plate 120, completing the screening process. Small particles pass through the screen holes and fall onto the second conveyor belt 150, while large particles roll down along the screen plate 120 onto the first conveyor belt 140. A vibration motor 121 is installed on the support frame 110. The vibrating end of the vibration motor 121 abuts against the screen plate 120, and the vibration motor 121 drives the entire screen plate 120 to vibrate, thereby accelerating the screening efficiency. A material distribution hopper 130 is connected to the top of the support frame 110 via a fixing frame 111. A material distribution component is provided at the bottom of the material distribution hopper 130. The material to be screened is fed into the material distribution hopper 130 and evenly spread on the screen plate 120 by the material distribution component, thereby avoiding material blockage and further enhancing screening efficiency. A flow channel 112 is provided on one side of the support frame 110 below the screen plate 120. A first conveyor belt 140 is provided at the bottom of the support frame 110. The end of the flow channel 112 away from the support frame 110 slopes downward and extends onto the first conveyor belt 140. Large particles of material along the rollers of the screen plate 120 will fall downward into the flow channel 112 and slide onto the first conveyor belt 140 after being guided by the flow channel 112. The first conveyor belt 140 is used to transport and transfer large particles of material. A second conveyor belt 150 is installed below the screen plate 120. Small particles passing through the screen holes will fall onto the second conveyor belt 150, which will then transport them to the periphery of the equipment for packaging or further processing. The material distribution component includes multiple discharge channels 131 connected below the distribution hopper 130 and located at the same horizontal level. The specific structure of the discharge channels 131 should match the disc-shaped guide component 132. A disc-shaped guide component 132 is installed at the intersection of the top of the discharge channel 131 and the distribution hopper 130. The disc-shaped guide component 132 can rotate within the discharge channel 131 under the drive of the linkage shaft 133. A linkage shaft 133 is installed through the hopper 130. One end of the linkage shaft 133 is connected to a drive motor 134. The linkage shaft 133 is coaxially connected to multiple disc-shaped guide components 132. When the drive motor 134 is turned on, it will drive the multiple disc-shaped guide components 132 to rotate together through the linkage shaft 133. The outer periphery of the disc-shaped guide component 132 is provided with a storage trough 132a. During the rotation of the disc-shaped guide component 132, when the storage trough 132a rotates to the top, the material to be screened in the hopper 130 will fill the storage trough 132a. As the disc-shaped guide component 132 rotates again, the storage trough 132a rotates to the bottom, and the material to be screened in the storage trough 132a will fall downwards onto the top of the screen plate 120.

[0023] As can be seen from the above, in this embodiment of the application, by setting components such as the first conveyor belt 140 and the second conveyor belt 150, the large and small particles of the screened material can be transferred to the outer periphery of the equipment respectively, so that the entire screening process can be carried out continuously and efficiently. This application also sets a material distribution component, which includes multiple feeding channels 131, a disc-shaped guide 132, a drive motor 134, and a linkage shaft 133. Thus, when the drive motor 134 drives the linkage shaft 133 to rotate, the disc-shaped guide 132 can receive the material in the distribution hopper 130 through the storage trough 132a set on it, and after rotation, the material is put into the screen plate 120, thereby ensuring that the material can fall evenly above the screen plate 120 and avoid material accumulation and blockage.

[0024] In some embodiments, a V-shaped collection bin 113 is fixed on the support frame 110. The top of the collection bin 113 is open and located below the screen plate 120, while the bottom of the collection trough is narrowed and extends to the top of the second conveyor belt 150. In this embodiment, with the above arrangement, small particles of material passing through the screen plate 120 will be guided by the collection trough and fall into the middle of the second conveyor belt 150 in a concentrated manner, further preventing material from spilling onto the outside of the second conveyor belt 150.

[0025] In some embodiments, a storage bin 160 is included, which is connected to the top of the distribution hopper 130 via a feeding device 161. In this embodiment, the storage bin 160 can be in various forms such as cylindrical or square, and its specific dimensions can be set according to actual requirements. The material in the storage bin 160 can be fed into the distribution hopper 130 via the feeding device 161, and then filtered after being buffered in the distribution hopper 130, enabling the equipment to achieve fully automated production and reduce labor costs.

[0026] In some embodiments, a dust collection hood 170 is included, which is fixed to the top of the screen plate 120. A negative pressure fan 171 is fixed to the top of the distribution hopper 130. The inlet end of the negative pressure fan 171 is connected to the dust collection hood 170 through a negative pressure pipe 172, and the outlet end of the negative pressure fan 171 extends into the distribution hopper 130. In this embodiment, through the above configuration, the negative pressure fan 171 can create negative pressure at the negative pressure pipe 172, thereby drawing the dust raised at the screen plate 120 into the distribution hopper 130 through the dust collection hood, reducing dust generated during the production process.

[0027] In some embodiments, the storage tanks 132a on two adjacent disc-shaped guide members 132 are staggered. In this embodiment, the staggered arrangement of the storage tanks 132a on two adjacent disc-shaped guide members 132 means that when the storage tank 132a on one of the guide members rotates to the top, the storage tank 132a on the adjacent disc-shaped guide member 132 will rotate to the bottom. This allows the material on the transverse side of the screen plate 120 to be relatively uniform during the process of the disc-shaped guide members 132 guiding the material to the screen plate 120.

[0028] In some embodiments, the disc-shaped guide member 132 is provided with a plurality of storage tanks 132a, which are distributed at intervals along the circumference of the disc-shaped guide member 132. In this embodiment, the above arrangement can increase the feeding speed of the disc-shaped guide member 132 to the screen plate 120.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although the foregoing embodiments have provided a detailed description of this application, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
