Description

Technical Field

[0001] The invention relates to the technical field of water treatment agent processing, in particular to a novel water treatment agent crushing and screening device and a use method thereof. Background Art

[0002] Water treatment agents refer to chemicals added during the water treatment process in order to remove most harmful substances in water (such as corrosive substances, metal ions, dirt and microorganisms, etc.) and obtain civil or industrial water that meets the requirements. During their preparation or use, they need to be crushed and screened to make uniform particles that meet different usage requirements, so that they can be better mixed with liquid materials and better exert the performance of the water treatment agent.

[0046] As an embodiment of the present invention, a method for using a novel water treatment agent crushing and screening device comprises the following steps:

[0047] S1: Pour the water treatment agent into the crushing box 51 and start the motor 3 55 to crush the water treatment agent;

[0048] S2: Start the second motor 49 to make the screening device 4 start screening;

[0049] S3: Start the motor 23 to make the collecting device 3 slide back and forth, and at the same time, the water treatment agent crushed in the first crushing device 5 can be sent to the screening device 4. At the same time, the screen drum 45 in the screening device 4 rotates to collect large particles and small particles respectively;

[0050] S4: The second crushing device 6 crushes the large particles of water treatment agent collected by the second receiving box 32 for a second time.

[0051] Example 1:

[0052] like Figure 1 、 3 As shown in FIG. 5 , in this embodiment, the water treatment agent is first placed in the crushing box 51, and the motor 3 55 is started to drive the stirring roller 1 54 to rotate, thereby crushing the water treatment agent. Since the two stirring rollers 1 54 in the crushing box 51 are engaged and connected by the gear 1 56 and the stirring rollers 1 54 are staggered with each other, the two stirring rollers 1 54 rotate in opposite directions, so that the water treatment agent is squeezed and crushed by the two stirring rollers 1 54, thereby improving the degree of crushing of the water treatment agent.

[0053] like Figure 3 、 7As shown in Figure 9, the starting motor 2 49 drives the rotating block 410 to rotate. Since the connecting block 2 411 is rotationally connected to the fixed block 3 412 and the cylinder 43 is slidingly connected to the slide rail 41, when the rotating block 410 rotates, it drives the connecting block 2 411 to slide the cylinder 43 back and forth in the slide rail 41, thereby screening the water treatment agent in the screen cylinder 45. At the same time, the screen cylinder 45 slides back and forth, driving the semicircular block 423 on the semicircular plate 42 to slide back and forth, thereby making the double-headed gear shaft 424 on the semicircular block 423 mesh with the rack 427 on the slide rail 41 and drive the gear 2 426 meshed with the other end of the double-headed gear shaft 424 to rotate, thereby making the stirring roller 2 425 on the gear 2 426 frequently stir the water treatment agent to prevent large particles of water treatment agent from blocking the small holes of the screen hole 1 46, thereby improving the screening efficiency, and making the water treatment agent fall into the collecting device 3 from the screen hole 1 46 or the screen hole 2 47 through the empty slot 44.

[0054] like Figure 1 、 2 As shown in , 7 and 8, the starting motor 23 drives the screw rod 22 to rotate. Since the connecting block 1 33 is threadedly connected to the screw rod 22 and is fixedly connected to the material receiving device 3, the material receiving device 3 slides along the slide groove 11, thereby causing the material receiving box 2 to move to the bottom of the pressure plate 62 in the second crushing device 6, and the material receiving box 1 31 moves to the bottom of the cylinder 43. At the same time, during the movement of the connecting block 1 33, the oblique square block 26 is pushed upward along the oblique side, thereby pushing the slide rod 25 to move upward, and pushing the fixed block 5 27 to move upward through the fixed block 44. At the same time, the fixed block 5 27 pushes the slide post 1 418 in the slide groove 3 28 to move upward, so that the slide post 1 418 drives the connecting block 3 417 and the connecting shaft 414 connected thereto to rotate, thereby driving the screen drum 45 fixedly connected to the connecting shaft 414 to rotate in the cylinder 43. During the rotation of the cylinder 43, the screen hole 1 46 and the screen hole 2 47 exchange positions, so that the original screen hole 2 47 coincides with the empty slot 44 and becomes The sieve hole 46 and the empty slot 44 overlap, and this process causes large particles to pass through the sieve hole 47 and fall into the sieve plate 34, becoming small particles that pass through the sieve hole 46 and fall into the material receiving box 31. When the motor 23 is reversed, this process is reversed; thus, by rotating the motor 23 forward and reverse, the positions of the sieve hole 46 and the sieve hole 47 are continuously exchanged, thereby continuously screening small particles into the material receiving box 31 and screening large particles onto the sieve plate 34 in the material receiving box 32; because the pressing plate 62 passes through The fixed block eight 64 is fixedly connected to the cylinder 43, so the cylinder 43 slides back and forth, driving the pressure plate 62 to slide back and forth in the fixed block seven 61. When the material receiving box two 32 moves to the bottom of the pressure plate 62, the sliding pressure plate 62 grinds the large particles of water treatment agent on the sieve plate 34 through the grinding block 63 under the pressure plate 62 and the sieve plate 34 on the material receiving box two 32, and drops them into the material receiving box two 32. At the same time, the baffle two 65 at the tail end of the pressure plate 62 can prevent large particles from falling.

[0055] like Figure 3 、 4 As shown in Figures 6 and 7, during the rotation of the screen drum 45, the connecting block 421 and the sliding post 2 422 are driven to rotate through the connecting shaft 414. Since the sliding post 2 422 is slidably connected to the chute 7 516 and the sliding block 2 514 is slidably connected to the chute 6 513, when the sliding post 2 422 rotates, it drives the limit block 515 to move upward through the chute 7 516, thereby causing the sliding post 3 518 on the protrusion 2 517 to slide along the inclined groove of the triangular annular groove 512. Since the square plate 511 follows the baffle 1 510 to slide in the chute 5 59, the sliding post 3 518 pushes the square plate 511 and the baffle 1 510 in the chute 5 59 through the triangular annular groove 512. The first pulverizing device 510 then slides inward, causing the square plate 511 and the baffle 1 510 to move outward to open the discharge chute 53, so that the water treatment agent falls into the hollow square block 57 through the discharge chute 53 and is blown into the cylinder 43 by the blower 58; when the slide column 3 518 slides to the other inclined groove of the triangular annular groove 512, the square plate 511 will slide in the opposite direction to close the discharge chute 53. When the limit block 515 descends, the slide column 3 518 descends in the straight groove of the triangular annular groove 512 and will not open or close the discharge chute 53. This process is to ensure that the first crushing device 5 only feeds when screening small particles, and prevents feeding when screening large particles, which would cause the water treatment agent to be completely screened out from the sieve hole 2 47.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention.
