Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a discharging device for preparing a passivating agent, comprising a box body 1, the box body 1 is used to provide a structural frame and support for the entire device, and to accommodate and install a screening component 5 and a crushing component 6. A feed hopper 2 is fixedly connected to the top of the box body 1, and the feed hopper 2 is used to put the passivating agent raw material into the interior of the box body 1, and is the input port of the passivating agent raw material. An outer edge 3 is fixedly connected to the outer wall of the box body 1, and four groups of symmetrically arranged supporting legs 4 are fixedly connected to the bottom surface of the outer edge 3. The outer edge 3 forms a protruding portion on the outer wall of the box body 1, which is used to provide support points for the four groups of supporting legs 4. The four groups of supporting legs 4 provide stable support for the box body 1, ensuring that the entire box body 1 maintains balance and stability during operation.

[0034] Reference Figure 2 - Figure 3The interior of the box 1 is provided with a screening assembly 5, which is used to screen the passivating agent raw material entering the box 1, so as to ensure that the size of the passivating agent raw material particles meets the requirements. The screening assembly 5 includes a collecting hopper 51, which is fixedly connected to the inner wall of the box 1, and is used to collect the passivating agent raw material entering the box 1 on the surface of the screen plate 56, so as to avoid excessive dispersion of the passivating agent raw material, and enable the crushing assembly 6 to fully cut and crush the passivating agent raw material. The bottom end of the collecting hopper 51 is fixedly connected with a channel 52, which is used for the passivating agent raw material to pass through, and provides installation and activity space for the screen plate 56. The inner wall of the channel 52 is fixedly connected with a protrusion 1 53 and a protrusion 2 54, and a guide rod 55 is connected between the protrusion 1 53 and the protrusion 2 54. There are four groups of protrusions 1 53, protrusions 2 54 and guide rods 55, and the four groups of protrusions 1 53, protrusions 2 54 and guide rods 55 are located at the four corners of the channel 52. The protrusions 1 53 and protrusions 2 54 are used to fix the guide rods 55. The inner wall of the channel 52 is slidably connected with a sieve plate 56, and the sieve plate 56 is used to screen the passivating agent raw material. The guide rod 55 penetrates and is slidably connected to the sieve plate 56. 6, the guide rod 55 is used to guide and position the sieve plate 56, so that the sieve plate 56 is more stable during the up and down movement, and a return spring 57 is sleeved on the outer wall of the guide rod 55. The protrusion 54 and the bottom of the sieve plate 56 are elastically connected by the return spring 57. The return spring 57 is used to elastically support the sieve plate 56, so that the sieve plate 56 is compressed and rebounded by the return spring 57 under the pressure of external force, so that the sieve plate 56 and the passivator raw material on the surface shake together, thereby preventing the sieve plate 56 from being blocked and increasing the speed of passing the passivator raw material.

[0035] Reference Figure 2 and Figure 4The crushing assembly 6 is arranged inside the box 1. The crushing assembly 6 is used to fully cut the passivating agent raw material on the surface of the screen plate 56. The crushing assembly 6 includes a rotating shaft 61. Both ends of the rotating shaft 61 are rotatably connected to the inner wall of the box 1. The outer wall of the rotating shaft 61 is fixedly connected to multiple array-distributed mounting plates 62. The output shaft of the motor 65 is connected to the multiple mounting plates 62 through the rotating shaft 61 to transmit power, so that the motor 65 can drive the multiple mounting plates 62 to rotate. A cutting knife 63 is fixedly connected to one end of the mounting plate 62, and an arc plate 64 is fixedly connected to the other end of the mounting plate 62. The mounting plate 62 is used to install the cutting knife 63 and the arc plate 64, so that the cutting knife 63, the arc plate 64 and the mounting plate 62 rotate synchronously, so that the passivating agent raw material is cut by the cutting knife 63. The arc plate 64 stirs the passivating agent raw material, so that the passivating agent raw material is fully cut and mixed, which improves the uniformity and crushing effect of the raw material, and prevents the raw material from being too concentrated in certain areas of the screen plate 56. The rotating shaft 61 is located at the eccentric position of the mounting plate 62. The length of the mounting plate 62 at one end of the arc plate 64 is greater than the length at one end of the cutting knife 63. The mounting plate 62 is centered on the rotating shaft 61, and the lengths of the two ends are different. The cutting knife 63 is at a certain distance from the surface of the sieve plate 56. During the rotation process, the cutting knife 63 will not contact the surface of the sieve plate 56, while the arc plate 64 contacts the surface of the sieve plate 56 during the rotation process and squeezes the surface of the sieve plate 56, so that the sieve plate 56 moves downward, and the return spring 57 is compressed and rebounded by the return spring 57, so that the sieve plate 56 shakes. A motor 65 is fixedly connected to the outer wall of the box body 1. The output end of the motor 65 penetrates and is rotatably connected to the inner wall of the box body 1. The output end of the motor 65 is fixedly connected to the end of the rotating shaft 61. A bracket is installed on the bottom surface of the motor 65 and is installed on the surface of the outer edge 3, so as to provide additional support for the motor 65. The motor 65 is used to drive the rotating shaft 61 to rotate, so that the entire crushing assembly 6 operates.

[0036] Reference Figure 1 - Figure 2 and Figure 5 The side wall of the box 1 is fixedly connected with an electric telescopic rod 7, and the bottom surface of the electric telescopic rod 7 is fixedly connected with a blanking plate 8. The blanking plate 8 fits with the bottom surface of the box 1. The entire bottom surface of the box 1 is inclined and open, which is the discharge port for the passivation agent raw material particles. The height of the blanking plate 8 is adjusted by controlling the lifting and lowering of the electric telescopic rod 7, thereby adjusting the size and flow rate of the discharge port to control the output of the passivation agent raw material. The surface of the blanking plate 8 is fixedly connected with two groups of symmetrically arranged protective plates 9, which fit with the side wall of the box 1. The two groups of protective plates 9 can prevent the passivation agent raw material particles from splashing out from both sides of the blanking plate 8.

[0037] Working principle: The passivator raw material is put into the interior of the box body 1 through the feed hopper 2, enters the collecting hopper 51, flows to the surface of the sieve plate 56 in the channel 52, and the passivator raw material is screened on the sieve plate 56. By starting the motor 65, power is transmitted to the mounting plate 62 through the rotating shaft 61, so that the cutting knife 63 and the arc plate 64 rotate synchronously with the rotating shaft 61, and the cutting knife 63 fully cuts the passivating agent raw material on the surface of the sieve plate 56 to ensure that the particle size meets the requirements. The mounting plate 62 is centered on the rotating shaft 61, and the lengths of the two ends are different. There is a certain distance between the cutting knife 63 and the surface of the sieve plate 56. During the rotation process, the cutting knife 63 will not contact the surface of the sieve plate 56, while the arc plate 64 contacts the surface of the sieve plate 56 during the rotation process and squeezes the surface of the sieve plate 56, so that the sieve plate 56 moves downward, and the return spring 57 is compressed by force, and rebounded by the return spring 57, so that the sieve plate 56 and the passivating agent raw material on the surface shake together, thereby preventing the sieve plate 56 from being blocked and increasing the speed of passing the passivating agent raw material. The height of the blanking plate 8 is adjusted by controlling the lifting of the electric telescopic rod 7, thereby adjusting the size and flow rate of the discharge port and controlling the output of the passivating agent raw material. The two sets of protective plates 9 can prevent the passivating agent raw material particles from splashing out from both sides of the blanking plate 8.
