Technical Field

[0001] The utility model relates to the technical field of screening equipment, in particular to a screening machine for processing sodium hydroxide. Background Art

[0002] Sodium hydroxide, commonly known as caustic soda, caustic soda, is a strong alkali with strong corrosiveness. It is generally in the form of flakes or particles. During the processing of sodium hydroxide, it is necessary to screen the sodium hydroxide. This device is called a screening machine for sodium hydroxide processing.

[0003] The existing screening machine for sodium hydroxide processing adopts a vibration motor installed on a spring, and uses the exciting force generated by the vibration motor to make the screening box bounce repeatedly, thereby screening the sodium hydroxide particles. However, with the repeated bouncing of the spring, the fatigue strength of the spring is greatly increased, and the expansion and contraction of the spring is reduced, resulting in the sodium hydroxide particles in the screening box being unable to be effectively bounced and landed. In order to effectively screen the sodium hydroxide particles, a screening machine for sodium hydroxide processing is proposed. Utility Model Content

[0007] Furthermore, the worm is rotatably connected to the fixed box, the worm and the worm wheel are both located inside the fixed box, and the eccentric wheel is located in front of the worm wheel.

[0008] Furthermore, the axis of the eccentric wheel is offset from the axis of the movable shaft, the eccentric wheel passes through the connecting frame, the connecting frame is in a square shape, and the front wall and the rear wall of the eccentric wheel are fixedly connected with a baffle corresponding to the connecting frame.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-2 A screening machine for processing sodium hydroxide includes a base plate 1 and a screening box 2. Support plates 3 are fixedly installed on both sides of the top of the base plate 1. A support seat 4 is fixedly installed on the top of the base plate 1 and behind the support plate 3. A fixing box 5 is fixedly installed on the top of the support seat 4. Mounting holes 8 are opened on the base plate 1 and on the outside of the support plate 3 and the support seat 4 for installing and disassembling the base plate 1.

[0020] Among them, a screening plate 9 is fixedly installed on the inner side wall of the screening box 2, and a screening hole is provided on the screening plate 9 for screening the sodium hydroxide particles according to size. The large sodium hydroxide particles remain on the screening plate 9, and the small sodium hydroxide particles remain on the inner bottom wall of the screening box 2. A feed port is provided on the top wall of the screening box 2, and a locking cover 10 is provided on the inner wall of the feed port. Open the locking cover 10 and pour the sodium hydroxide particles into the screening box 2 for screening.

[0021] In addition, a discharge port is provided on the front wall of the screening box 2, and an opening and closing assembly 11 is provided on the inner wall of the discharge port. The opening and closing assembly 11 includes a baffle 111 and a mounting screw 112. The baffle 111 is inserted into the inner wall of the discharge port to prevent sodium hydroxide particles from falling out of the screening box 2 during the vibration screening process. The mounting screw 112 passes through the baffle 111 and is threadedly connected to the screening box 2. Unscrew the mounting screw 112 and remove the baffle 111 to discharge the screened sodium hydroxide particles.

[0022] See also Figure 3-4 A vibration assembly 6 for continuous screening of sodium hydroxide is provided on the screening box 2, the support plate 3 and the fixed box 5. The vibration assembly 6 includes a motor 61, a worm 62, a movable shaft 63, a worm gear 64, an eccentric wheel 65 and a connecting frame 66. The motor 61 is fixedly mounted on the side wall of the fixed box 5, and the worm 62 is fixedly mounted on the output shaft of the motor 61. The worm 62 is rotatably connected to the fixed box 5 and is used to support both ends of the worm 62. The movable shaft 63 is rotatably connected between the support plate 3 and the opposite side of the fixed box 5. The worm gear 64 is fixedly mounted on the outer surface of the movable shaft 63. The worm 62 is engaged with the worm gear 64. When the motor 61 is started, the worm 62 rotates, driving the worm gear 64 to engage and rotate, and the movable shaft 63 rotates accordingly, gradually performing the screening of sodium hydroxide. The worm 62 and the worm gear 64 are both located inside the fixed box 5.

[0023] The eccentric wheel 65 is fixedly mounted on the outer surface of the movable shaft 63 and can rotate along with the movable shaft 63. The eccentric wheel 65 is located in front of the worm gear 64. The axis of the eccentric wheel 65 is offset from the axis of the movable shaft 63, that is, the axis of the eccentric wheel 65 is not in the same straight line as the axis of the movable shaft 63. The connecting frame 66 is fixedly mounted on both ends of the side walls of the screening box 2. The eccentric wheel 65 is movably connected to the inner wall of the connecting frame 66. The eccentric wheel 65 passes through the connecting frame 66. Because the axis of the eccentric wheel 65 is not in the same straight line as the axis of the movable shaft 63, the rotation of the eccentric wheel 65 can drive the connecting frame 66 to move along a circular trajectory, thereby allowing the sodium hydroxide particles on the screening plate 9 to vibrate continuously, thereby realizing the screening function of the sodium hydroxide particles. The connecting frame 66 is in the shape of a square. The front wall and the rear wall of the eccentric wheel 65 are fixedly connected with a baffle 7 corresponding to the connecting frame 66, which is used to resist the connecting frame 66 and prevent the eccentric wheel 65 from separating from the connecting frame 66.

[0024] When this embodiment is in use, the locking cover 10 is opened, sodium hydroxide particles are poured into the screening box 2, the locking cover 10 is closed, the motor 61 is started, the worm 62 rotates, the worm gear 64 engages and rotates, and drives the eccentric wheel 65 to rotate. Because the axis of the eccentric wheel 65 and the axis of the movable shaft 63 are not on the same straight line, the rotation of the eccentric wheel 65 can drive the connecting frame 66 to move along a circular trajectory, so that the screening plate 9 can be shaken, thereby vibrating and screening the sodium hydroxide particles. Large sodium hydroxide particles are intercepted on the screening plate 9, and small sodium hydroxide particles fall into the inner bottom wall of the screening box 2. After the screening is completed, the mounting screws 112 are screwed, the baffle 111 is removed, and the screened sodium hydroxide particles are discharged.

[0025] The beneficial effects of the above embodiment are:

[0026] The screening machine for processing sodium hydroxide is provided with a vibration component 6. After the vibration component 6 is used and the motor 61 is started, the worm 62 rotates to drive the worm wheels 64 on both sides to rotate. Under the connection of the movable shaft 63, the eccentric wheel 65 rotates accordingly. Because the axis of the eccentric wheel 65 and the axis of the movable shaft 63 are not on the same straight line, the rotation of the eccentric wheel 65 can push the connecting frame 66 together with the screening box 2 to shake along a circular trajectory, so that the sodium hydroxide particles in the screening box 2 can vibrate continuously, realizing the screening function of the sodium hydroxide particles. Because no spring is provided, the fatigue strength caused by repeated bouncing is avoided to affect the effective screening of the sodium hydroxide particles.

[0027] The motor 61 mentioned in the text is electrically connected to a main controller and a power supply. The main controller can be a conventional known device for controlling a computer, etc., and the existing disclosed power connection technology is not described in detail in the text.
