Therefore, the utility model provides a small automatic solid feeder. Summary of the Utility Model

Specific implementation manners

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides two technical solutions:

[0025] Embodiment 1

[0026] A small automatic solid feeder includes a glass container 1 and a feeding funnel 2. The surface of the glass container 1 is provided with scales. The glass of this feeder is made of high borosilicate glass, which has the advantages of strong corrosion resistance, good rigidity, convenient permeability for observation, and smooth inner surface. The bottom of the feeding funnel 2 is fixedly connected with a connecting pipe 3. The surface of the feeding funnel 2 is provided with a fixing assembly 4. The inside of the glass container 1 is provided with a feeding mechanism 5, and the feeding mechanism 5 includes:

[0027] A feeding assembly 51, including a stepping motor 511. A small stepping motor is used for the feeding power, giving full play to the advantages of high rotational speed and accurate speed control of the stepping motor, so as to realize quantitative automatic feeding. One end of the output shaft of the stepping motor 511 is fixedly connected with a stirrer 512 through a coupling. The stirrer 512 is made of a new material PEEK. PEEK polyetheretherketone is a special engineering plastic with excellent properties such as corrosion resistance, high temperature, self-lubrication, easy processing, and high mechanical strength, which well solves the problems existing in the screw of the tetrafluoro material as the feeding valve in the traditional feeder. The surface of the stirrer 512 is fixedly connected with a rod-shaped stirring blade 513 and a propelling stirring blade 514. The bottom end of the stirrer 512 is fixedly connected with a propelling screw 515;

[0028] The sealing assembly 52 is arranged at the upper end of the glass container 1. A connecting flange 6 is installed on the surface of the glass container 1. A discharge port 7 is opened at the bottom end of the glass container 1. The sealing assembly 52 includes a glass feeder cover 521 installed at the upper end of the glass container 1. An air vent 522 is opened on the right side of the upper end of the glass feeder cover 521. A feeding port 523 is opened on the left side of the upper end of the glass feeder cover 521. A stirring feeding seal 524 is installed at the center of the upper end of the glass feeder cover 521. A vacuum valve 8 is arranged on the inner surface of the air vent 522. A feeding port cover 9 is arranged on the inner surface of the feeding port 523. Through the feeding mechanism 5 and the sealing assembly 52, automation and quantification are realized, the error of manual feeding operation is reduced, the chemical reaction is made more accurate, the operation of experimental personnel is facilitated at the same time, and accurate feeding of several solids is successfully carried out simultaneously, reducing the labor cost and increasing the social benefit.

[0029] Embodiment 2

[0030] The main difference from Embodiment 1 is that:

[0031] A small automatic solid feeder. The fixing assembly 4 includes a connecting piece 41 installed on one side of the feeding funnel 2. A fixing block 42 is slidably connected inside the connecting piece 41. Sliders are installed on both sides of the fixing block 42. A chute is opened on the inner wall of the connecting piece 41. The sliders are slidably limited on the inner surface of the chute. The surface of the fixing block 42 is slidably connected with the inside of the feeding funnel 2. One side of the fixing block 42 is fixedly connected with a spring 43. One end of the spring 43 is fixedly connected with the inner wall of the connecting piece 41. A lever 44 is slidably connected inside the connecting piece 41. The bottom end of the lever 44 is fixedly connected with an inclined slider 45. An inclined chute 10 is opened at the top of the fixing block 42. The inner surface of the inclined chute 10 is slidably connected with the inclined surface of the inclined slider 45. By providing the fixing assembly 4, when an experimental personnel feeds materials into the glass container 1 through the feeding funnel 2, the feeding funnel 2 can be more stably placed at the feeding port 523, avoiding the situation of slipping and causing the fixed materials to scatter, improving the stability of the feeding process. At the same time, the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0032] During operation, first insert the connecting pipe 3 at the bottom of the feeding funnel 2 into the feeding port 523. At this time, the annular opening on the surface of the feeding port 523 is located within the notch between the connecting pipe 3 and the feeding funnel 2 and contacts one end of the fixed block 42, thereby squeezing the fixed block 42 and the spring 43, causing the left side of the fixed block 42 to slide. When the annular opening on the surface of the feeding port 523 slides past the fixed block 42, the fixed block 42 is reset under the influence of the elasticity of the spring 43, so that one end of the fixed block 42 fits on the surface of the feeding port 523 and cooperates with the annular opening to remain fixed. Subsequently, use the feeding funnel 2 and the connecting pipe 3 to add solid materials into the glass container 1 through the feeding port 523. Determine the total feeding capacity through the capacity scale on the surface of the glass container 1. After feeding, press down the lever 44 to make the inclined slider 45 slide into the internal inclined chute 10, thereby causing the fixed block 42 to slide to the left, and one end of the fixed block 42 is separated from the surface of the feeding port 523, so as to remove the feeding funnel 2 and cover the feeding port cover 9 to isolate the feeder from the ambient atmosphere. Connect to the vacuum system of the reactor through the vacuum valve 8 on the vent port 522 to ensure that the gas pressure above the material is the same as that in the reactor and avoid the influence of air pressure during feeding. Start the stepping motor 511 and maintain the pre-designed rotation speed, so as to ensure that the material enters the reactor through the discharge port 7 at a set speed and participates in the reaction in a timely manner. During the process, the stepping motor 511 has a high rotation speed and accurate speed control, which can make the pitch of the propulsion screw 515 finer and the feeding more accurate; the operation of the propulsion stirring blade 514 makes the material in the lower part denser and the feeding more accurate; the operation of the rod-shaped stirring blade 513 makes the upper material fall in time, reduces the appearance of hollow phenomenon, and the feeding is more accurate; the discharge port 7 and the propulsion screw 515 extend below the connecting flange 6, which can reduce the material staying at the discharge port 7 or on the inner wall of the reactor, and the actual feeding is more accurate.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
