Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, and in particular relates to a sand screening device for water conservancy projects. Background Technology

[0002] In water conservancy projects, traditional sand and gravel screening mainly relies on manual screening or simple mechanical screening. These methods have many shortcomings, such as low screening efficiency, high labor costs, and unstable screening quality. With the advancement of technology and the development of water conservancy projects, the requirements for sand and gravel screening equipment are becoming increasingly stringent.

[0003] The sand screening device used in this water conservancy project solves the problems of low screening efficiency, complicated operation and poor screening effect of existing sand screening equipment. By designing a motor-driven transmission component, the reciprocating motion of the sand screening component is realized, which improves the screening efficiency. At the same time, the sand is screened by using two layers of filter plates, which effectively removes impurities and improves the quality of the sand. In addition, a cleaning mechanism is set up to automatically clean the sand on the filter plates and avoid the decline in screening efficiency caused by sand accumulation. Utility Model Content

[0026] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 6 As shown in the figure, an embodiment of this utility model provides a sand screening device for water conservancy projects, comprising:

[0029] The support mechanism 100 includes a support frame 101, and an output component 102 is provided on the top of the support frame 101;

[0030] The output component 102 includes a motor 102a disposed on the top of the support frame 101. The output end of the motor 102a is connected to an output rod 102b, and a transmission component 103 is disposed on the surface of the output rod 102b.

[0031] The transmission assembly 103 includes a first pulley 103-1 that is connected to one side of the output rod 102b. A second pulley 103-2 is connected to the surface of the first pulley 103-1 via a belt. A connecting rod 103-3 is provided on the second pulley 103-2. A rotating block 103a is located on one side of the connecting rod 103-3. A rotating rod 103b is rotatably connected to one side of the rotating block 103a. A connecting block 103c is located on one side of the rotating rod 103b.

[0032] The sand screening mechanism 200 includes two sets of sand screening components 201 disposed on the top of the support frame 101. The two sets of sand screening components 201 are the first sand screening component 202 and the second sand screening component 203, respectively.

[0033] refer to Figure 1 ,6 The first sand screening assembly 202 includes a first fixing plate 202a disposed on the top of the support frame 101, a first filter plate 202b disposed on the inner wall of the first fixing plate 202a, a first pulley 202c disposed at the bottom of the first filter plate 202b, the bottom of the first pulley 202c disposed on the top of the support frame 101, and the right side of the first fixing plate 202a being fixedly connected to the left side of the connecting block 103c.

[0034] By adopting the above scheme, the combination of the first fixing plate 202a, the first filter plate 202b and the first pulley 202c achieves the initial screening of sand and effectively removes larger impurities. The fixed connection between the first fixing plate 202a and the connecting block 103c enhances the structural strength of the sand screening component 201.

[0035] refer to Figure 1 , 6 The second sand screening assembly 203 includes a second fixing plate 203a disposed on the top of the support frame 101, a second filter plate 203b disposed on the inner side of the second fixing plate 203a, a second pulley 203c disposed at the bottom of the second fixing plate 203a, and the bottom of the second pulley 203c disposed on the top of the support frame 101.

[0036] The above scheme is adopted: the second sand screening component 203 is similar to the first sand screening component 202, but uses a filter plate with a different pore size, which realizes further screening of sand and improves the quality of sand. The design of the second pulley 203c enables the second sand screening component 203 to move smoothly during the sand screening process, thereby improving the sand screening efficiency.

[0037] refer to Figure 1 , 3 Electric push rods 204 are provided on the right side of the first fixed plate 202a and the second fixed plate 203a. The output end of the electric push rod 204 is connected to a cleaning plate 205. The bottom of the cleaning plate 205 is in contact with the surface of the first filter plate 202b and the second filter plate 203b.

[0038] The above solution achieves automatic cleaning of the filter plate through the combination of electric push rod 204 and cleaning plate 205, avoiding sand accumulation on the filter plate and ensuring the continuous and efficient operation of the sand screening device. The contact design between the cleaning plate 205 and the filter plate ensures the cleaning effect.

[0039] refer to Figure 1 , 4A fixing post 206 is provided on the right side of the first fixing plate 202a. A pressing groove 207 is provided on the right side of the fixing post 206. A first spring 208 is provided on the surface of the pressing groove 207. A positioning post 209 is provided on the right side of the first spring 208. The right side of the positioning post 209 extends to the right side of the positioning pin 210. The positioning pin 210 is located inside the connecting block 103c and the rotating rod 103b.

[0040] The above solution, through the combination of fixed column 206, extrusion groove 207, first spring 208 and positioning column 209, realizes the positioning function of connecting block 103c and rotating rod 103b, ensuring the stability and accuracy of sand screening assembly 201 in the sand screening process. Through the design of push plate 211, users can easily adjust the position of positioning column 209, thereby realizing flexible control of sand screening assembly 201.

[0041] refer to Figure 1 , 4 The surface of the positioning post 209 is provided with a push plate 211, which is used to push the positioning post 209.

[0042] The above solution is adopted: the design of the push plate 211 not only pushes the positioning column 209, but also increases the convenience of user operation, making the adjustment and maintenance of the sand screening device simpler.

[0043] refer to Figure 1 , 5 The first fixing plate 202a and the second fixing plate 203a are both provided with a pull groove 212. Two second springs 213 are provided on the surface of the pull groove 212. A pull rod 214 is provided on the left side of each of the two second springs 213. A closing plate 215 is provided on the left side of the pull rod 214. The right side of the closing plate 215 is in contact with the left side of the first fixing plate 202a and the second fixing plate 203a.

[0044] The above solution is adopted: by combining the pull groove 212, the second spring 213, the pull rod 214 and the closing plate 215, the closing function of the sand screening component 201 is realized, which avoids the leakage of sand during the sand screening process and improves the sand screening efficiency. The contact design between the closing plate 215 and the first fixed plate 202a and the second fixed plate 203a ensures the sealing of the sand screening device.

[0045] The working principle of this utility model:

[0046] When using this sand screening device;

[0047] The entire sand screening device is based on the support mechanism 100, and the motor 102a installed on the support frame 101 serves as the power source.

[0048] After the motor 102a starts, its output end drives the output rod 102b to rotate. The transmission component 103 on the surface of the output rod 102b rotates accordingly. The rotating block 103a in the transmission component 103 is rotatably connected to the rotating rod 103b, so that the rotating rod 103b can swing with the rotation of the rotating block 103a. The connecting block 103c provided on one side of the rotating rod 103b is fixedly connected to the first fixing plate 202a of the first sand screening component 202. When the rotating rod 103b swings, the first sand screening component 202 is driven to move on the support frame 101 through the connecting block 103c. In reciprocating motion, the first filter plate 202b inside the first sand screening assembly 202 performs preliminary screening of the sand, filtering out larger impurities. At the same time, the first pulley 202c makes the first sand screening assembly 202 move more smoothly and reduces frictional resistance. The working principle of the second sand screening assembly 203 is similar to that of the first sand screening assembly 202, but it uses filter plates with different pore sizes to achieve further screening of the sand. The second filter plate 203b inside the second fixed plate 203a has finer sieve holes, which can remove smaller impurities, thereby improving the quality of the sand.

[0049] In order to keep the filter plate clean, the device is also equipped with a cleaning mechanism. The output end of the electric push rod 204 is connected to the cleaning plate 205. When the electric push rod 204 extends and retracts, the cleaning plate 205 moves back and forth on the surface of the filter plate under the action of the electric push rod 204, thereby removing the sand attached to the filter plate and ensuring the sand screening efficiency.

[0050] In addition, the device enhances the stability of the structure through positioning and closing mechanisms. The positioning column 209 can be easily adjusted in position under the action of the push plate 211 to fix and disassemble the sand screening component 201. The closing plate 215 is tightly attached to the left side of the first fixed plate 202a and the second fixed plate 203a under the action of the second spring 213, which prevents sand from leaking out during the sand screening process.

[0051] In summary, this sand screening device for water conservancy projects solves the problems of low screening efficiency, complex operation, and poor screening effect of existing sand screening equipment.
