[0002] Plasma spraying powder mixing refers to mixing different types and properties of powder materials together to obtain plasma spraying coatings with required performance and quality. Plasma spraying is a process in which the spraying material is heated and accelerated by a high-temperature and high-pressure gas flow generated by a plasma arc and sprayed onto the surface of a substrate to form a coating.

[0003] Plasma spraying powder mixing is one of the important links in the plasma spraying process. The mixing quality directly affects the performance and quality of the coating. Therefore, it is necessary to strictly control the mixing process to ensure that the powder is evenly mixed to obtain high-quality plasma spraying coatings.

[0004] In the process of mixing powders in the prior art, the agglomerated powders cannot be fully dispersed, resulting in affecting the uniformity of powder mixing, and there is a lack of a quantitative weighing structure for the mixed powders. Summary of the Invention

[0005] The purpose of the utility model is to provide a mixing device for plasma spraying powder, which can collide and disperse the agglomerated powders, thereby avoiding the influence of the agglomerated powders on the uniformity of the mixing of various powders, and realizing the quantitative mixing of the powders, so as to ensure the mixing quality and obtain high-quality plasma spraying coatings.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A mixing device for plasma spraying powder, including a mixing device body, a stirring mechanism is installed inside the mixing device body, a discharge pipe with an electromagnetic valve installed on the outer wall is communicated with the lower end surface of the mixing device body, a feeding channel is arranged on the right side of the mixing device body, a connecting cavity communicated with the mixing device body is communicated on the left side of the feeding channel, a weighing device is installed at the bottom end inside the feeding channel, a pushing plate is placed on the upper end surface of the weighing device, and an electric push rod with an output end fixedly connected to the pushing plate is installed on the right side of the feeding channel;

[0007] A separation cavity is communicated with the upper end surface of the feeding channel, a mesh plate is installed inside the separation cavity, a protrusion is fixedly connected to the upper end surface of the mesh plate, extension plates are fixedly connected to both the left and right sides of the mesh plate, vibration motors are installed on the upper end surfaces of the two extension plates, and elastic components are installed on both the left and right sides of the lower end surface of the mesh plate.

[0008] In order to open the connection part between the connection cavity and the blanking channel, as an optimization of the plasma spraying powder mixing device of the present utility model, a baffle is movably connected to the connection part between the connection cavity and the blanking channel through a rotating shaft, and a pushing plate is fixedly connected to the upper end surface of the pushing plate.

[0009] In order to remind the staff that the fallen powder has reached the set weight value, as an optimization of the plasma spraying powder mixing device of the present utility model, an alarm is installed on the right side of the blanking channel.

[0010] In order to facilitate the feeding of the powder to be mixed into the separation cavity, as an optimization of the plasma spraying powder mixing device of the present utility model, a material guiding groove is installed on the lower end surface of the mesh plate, and a feed port connected with a sealing cover in a threaded manner is communicated with the upper end surface of the separation cavity.

[0011] In order to support the blanking channel, as an optimization of the plasma spraying powder mixing device of the present utility model, a support frame for supporting the blanking channel is fixedly connected to the right side of the mixing device body.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] When the present utility model is in use, the vibration motor operates, and the output end of the vibration motor drives the mesh plate to vibrate, shaking the caked powder on the upper end surface of the mesh plate. At the same time, in cooperation with the protrusions, since the protrusions are relatively sharp, the caked powder can be collided and dispersed when the caked powder falls, thereby preventing the caked powder from affecting the uniformity of the mixing of various powders.

[0015] The dispersed powder falls into the blanking channel and lands on the weighing device for weighing until the set weight value is reached. Then, the pushing plate pushes the powder that has landed on the weighing device into the connection cavity, and smoothly enters the mixing device body through the inclined connection cavity, realizing the quantitative mixing of the powder, thereby ensuring the mixing quality to obtain high-quality plasma spraying coatings.

[0022] Please refer to Figures 1 to 3 , a mixing device for plasma spraying powder, comprising a mixing device body 1, a stirring mechanism 101 is installed inside the mixing device body 1, a discharge pipe 102 with a solenoid valve installed on the outer wall is communicated with the lower end surface of the mixing device body 1, a feeding channel 3 is arranged on the right side of the mixing device body 1, a connecting cavity 301 communicated with the mixing device body 1 is communicated with the left side of the feeding channel 3, a weighing device 302 is installed at the bottom end inside the feeding channel 3, a pushing plate 304 is placed on the upper end surface of the weighing device 302, and an electric push rod 306 with an output end fixedly connected to the pushing plate 304 is installed on the right side of the feeding channel 3;

[0023] The upper end surface of the blanking channel 3 is communicated with a separation cavity 2. A wire mesh plate 201 is installed inside the separation cavity 2. A protrusion 202 is fixedly connected to the upper end surface of the wire mesh plate 201. Extension plates are fixedly connected to both the left and right sides of the wire mesh plate 201. Vibration motors 205 are installed on the upper end surfaces of the two extension plates. Elastic components 204 are installed on both the left and right sides of the lower end surface of the wire mesh plate 201.

[0024] In this embodiment: The powder materials to be mixed are put on the wire mesh plate 201 inside the separation cavity 2. At the same time, the vibration motor 205 drives the wire mesh plate 201 to vibrate, so as to shake off the caked powder materials on the upper end surface of the wire mesh plate 201. And with the cooperation of the protrusion 202, when the caked powder materials fall, due to the protrusion 202 being relatively sharp, the caked powder materials can be collided and dispersed, thus avoiding the influence of the caked powder materials on the uniformity of the mixing of various powder materials.

[0025] And with the vibration of the wire mesh plate 201, the dispersed powder materials can fall into the blanking channel 3 and land on the weighing device 302. Then, through the weighing device 302, the powder materials falling can be weighed. Until the required amount is reached, then the electric push rod 306 can be used to push the push plate 304 to move leftward, pushing the powder materials that have fallen on the weighing device 302 into the connection cavity 301, and smoothly entering the mixing device body 1 through the inclination of the connection cavity 301, thus realizing the effect of quantitatively mixing the powder materials, ensuring the mixing quality, and obtaining high-quality plasma spraying coatings.

[0026] As a technical optimization scheme of the present utility model, a baffle 303 is movably connected to the communicating part between the connection cavity 301 and the blanking channel 3 through a rotating shaft. A push plate 305 is fixedly connected to the upper end surface of the push plate 304.

[0027] In this embodiment: The baffle 303 can be used to block the powder materials falling into the blanking channel 3. By pushing the push plate 305 to move leftward with the electric push rod 306, the baffle 303 can be pushed, prompting to open the connection part between the connection cavity 301 and the blanking channel 3, so that the quantitative powder materials can smoothly fall into the mixing device body 1.

[0028] As a technical optimization scheme of the present utility model, an alarm 307 is installed on the right side of the blanking channel 3.

[0029] In this embodiment: When the powder materials falling on the weighing device 302 reach the set weight value, the alarm 307 can give an alarm to remind the staff.

[0030] As a technical optimization scheme of the present utility model, a material guiding groove 203 is installed on the lower end surface of the wire mesh plate 201. The upper end surface of the separation cavity 2 is communicated with a feed inlet which is threadedly connected with a sealing cover.

[0031] In this embodiment: Through the material guiding groove 203, the scattered powder can smoothly fall into the blanking channel 3, and the powder to be mixed can be input into the separation cavity 2 through the feeding port.

[0032] As a technical optimization scheme of the present utility model, a support frame 308 for supporting the blanking channel 3 is fixedly connected to the right side of the mixing device body 1.

[0033] In this embodiment: The support frame 308 is used to support the blanking channel 3.

[0034] As a technical optimization scheme of the present utility model, a controller 4 is installed on the upper end surface of the separation cavity 2, and the vibration motor 205, the weighing device 302, the electric push rod 306 and the alarm 307 are all electrically connected to the controller 4.

[0035] In this embodiment: Through the controller 4, the vibration motor 205, the weighing device 302, the electric push rod 306 and the alarm 307 can be controlled to work.

[0036] Working principle: First, the powder to be mixed is input onto the mesh plate 201 in the separation cavity 2 through the feeding port. At the same time, the vibration motor 205 works, and the output end of the vibration motor 205 drives the mesh plate 201 to vibrate. The elastic component 204 assists the mesh plate 201 to vibrate, and the caked powder on the upper end surface of the mesh plate 201 can be shaken loose. And in cooperation with the protrusions 202, since the protrusions 202 are relatively sharp, the caked powder can be collided and scattered when the caked powder falls. As the mesh plate 201 vibrates, the scattered powder can fall into the blanking channel 3 through the material guiding groove 203 and land on the weighing device 302. The weighing device 302 can weigh the falling powder. When the set weight value is reached, the alarm 307 emits an alarm to remind the staff to close the solenoid valve on the outer wall of the blanking channel 3. Then, the electric push rod 306 can be used to push the push plate 304 and the push board 305 to move leftward. The push board 305 pushes the baffle 303, causing the baffle 303 to rotate around the rotating shaft, and opening the connection part between the connection cavity 301 and the blanking channel 3. The push plate 304 pushes the powder that has fallen on the weighing device 302 into the connection cavity 301, and smoothly enters the mixing device body 1 through the inclination of the connection cavity 301. Finally, the powder in the mixing device body 1 is mixed and stirred by the stirring mechanism 101. After the mixing is completed, it is discharged through the discharge pipe 102.

[0037] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
