Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This embodiment provides a technical solution: a production device for calcium hydroxide processing without solid waste, including a crushing shell 1, with a sliding groove 4 opened in the middle of the left and right side walls of the crushing shell 1, and a crushing mechanism 3. A control switch group 6 is provided at the front right end of the crushing shell 1, and the input end of the control switch group 6 is electrically connected to an external power source. A crushing shell door 8 is hinged to the front of the crushing shell 1 through a hinge. A feed inlet 2 is opened at the upper end of the crushing shell 1, and a discharge outlet 5 is opened at the lower end of the crushing shell 1.

[0024] Crushing mechanism 3 includes a slider 31, a first crushing roller 32, a bidirectional screw 34, a second crushing roller 35, gears 36, and a filter assembly 39. Sliding sliders 31 are symmetrically distributed inside the first chute 4. A first crushing roller 32 is rotatably connected between two laterally adjacent sliders 31. A bidirectional screw 34 is rotatably connected between the front and rear sidewalls of the first chute 4 on the right side. The bidirectional screw 34 is threadedly connected to two longitudinally adjacent sliders 31. A second crushing roller 35 is symmetrically distributed between the left and right sidewalls of the crushing shell 1. A rotating rod 7 is rotatably connected to the left side of each second crushing roller 35. A gear 36 is provided on the left side of each rotating rod 7, and the two gears 36 mesh with each other. The filter assembly 39 includes a second chute 391 and a filter screen 392. The lower end of each wall is provided with symmetrically distributed sliding grooves 391. A filter screen 392 is slidably connected between the four sliding grooves 391. The crushing mechanism 3 also includes a motor 33, which is located to the left of the slider 31 on the left side. The output shaft of each motor 33 passes through a circular hole on the left side of the slider 31 and is fixedly connected to the left side of the adjacent crushing roller 32. The input end of the motor 33 is electrically connected to the output end of the control switch group 6. The crushing mechanism 3 also includes a second motor 37, which is located to the left side of the crushing shell 1. The right end of the output shaft of the second motor 37 passes through a circular hole on the left side of the crushing shell 1 and is fixedly connected to the middle left side of the gear 36 located on the front side. The input end of the second motor 37 is electrically connected to the output end of the control switch group 6. The crushing mechanism 3 also includes... The filter assembly 39 includes a knob 38, which is located on the front side of the bidirectional lead screw 34. The filter assembly 39 also includes a top block 393 and a motor 394. The top block 393 is rotatably connected to the lower end of the left side wall of the crushing shell 1. The motor 394 is located on the left side of the crushing shell 1. The right end of the output shaft of the motor 394 passes through a circular hole on the left side of the crushing shell 1 and is fixedly connected to the middle left side of the top block 393. The input end of the motor 394 is electrically connected to the output end of the control switch group 6. First, the knob 38 needs to be rotated. The knob 38 drives the bidirectional lead screw 34 to rotate, which in turn drives the transmission slider 31 to move the crushing roller 32 along the slide groove 4 in opposite directions, thereby adjusting the distance between the two crushing rollers 32. Then, the control switch group 6 is used to turn on the motor 33 and the second motor 37. The motor 33 drives... The rotating crushing roller 32 drives the front gear 36 to rotate, which in turn drives the rear gear 36 to rotate, causing the two crushing rollers 35 to rotate. Then, calcium hydroxide raw material is poured into the crushing shell 1 from the feed inlet 2. The calcium hydroxide raw material is crushed into small pieces by the crushing roller 32, and then crushed into powder by the crushing roller 35, finally falling onto the top of the filter screen 392. Then, the control switch group 6 activates the motor 394, which drives the top block 393 to rotate. Since the top block 393 is elliptical, when the major axis of the top block 393 rotates to the vertical position, it will lift the filter screen 392 upwards, causing the filter screen 392 to slide upwards along the sliding groove 391. When the minor axis of the top block 393 rotates to the vertical position, the filter screen 392 loses its upward lifting force.Under the pressure of calcium hydroxide, it moves downward along the chute 391, causing the filter screen 392 to repeatedly move up and down and shake, thus screening the calcium hydroxide powder and dropping it out of the crushing shell 1 from the discharge port 5. The calcium hydroxide undergoes two crushing processes through crushing rollers 32 and 35, resulting in better crushing. The crushed calcium hydroxide powder is then screened through the filter screen 392 to ensure that there are no large solid particles, thus improving the usability of the calcium hydroxide.

[0025] The working principle of the production device for calcium hydroxide processing without solid waste provided by this utility model is as follows: When processing calcium hydroxide, the distance between the two crushing rollers 32 needs to be adjusted according to the size of the calcium hydroxide raw material fixed block. First, the knob 38 is rotated, which drives the bidirectional lead screw 34 to rotate, and the transmission slider 31 drives the crushing rollers 32 to slide in opposite directions along the slide groove 4, thereby adjusting the distance between the two crushing rollers 32. Then, the control switch group 6 is used to turn on the motors 33 and 37. The motor 33 drives the crushing rollers 32 to rotate, and the motor 37 drives the gear 36 located on the front side to rotate, driving the gear 36 located on the rear side to rotate, thus rotating the two crushing rollers 35. Then, the calcium hydroxide raw material is poured into the interior of the crushing shell 1 from the feed inlet 2, and the calcium hydroxide raw material is crushed... The crushing roller 32 breaks the particles into small pieces, which are then crushed into powder by the crushing roller 35. The powder eventually falls onto the top of the filter screen 392. The motor 394 is then activated by the control switch group 6, which drives the top block 393 to rotate. Since the top block 393 is an elliptical top block, when the major axis of the top block 393 rotates to the vertical position, it will lift the filter screen 392 upward, causing the filter screen 392 to slide upward along the slide groove 391. When the minor axis of the top block 393 rotates to the vertical position, the filter screen 392 loses the upward force and will move downward along the slide groove 391 under the pressure of the calcium hydroxide. This causes the filter screen 392 to move up and down repeatedly and shake, thus screening the calcium hydroxide powder and allowing it to fall out of the crushing shell 1 from the discharge port 5. If any calcium hydroxide powder particles are too large, the crushing shell door 8 can be opened to remove the oversized calcium hydroxide powder and put it back into the feed port 2 for further crushing.

[0026] It is worth noting that, in the above embodiments, motor 33 can be YLJ180-200 / 6, motor 37 can be ZD380-1590, and motor 394 can be THA130302B. The control switch group 6 is provided with buttons that correspond one-to-one with motor 33, motor 37 and motor 394 and control their switching.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
