Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary feeding devices, specifically to an auxiliary feeding machine. Background Technology

[0002] The high-frequency infrared carbon-sulfur analyzer is an analytical instrument based on high-frequency induction combustion-infrared absorption method, used to rapidly and accurately determine the carbon and sulfur content in materials. Its working principle involves burning the sample at high temperature in a high-frequency induction furnace, converting carbon and sulfur into carbon dioxide and sulfur dioxide gases. These gases have absorption characteristics for specific wavelengths of infrared light (CO2 has strong absorption bands at 4.26 μm, and SO2 at 7.4 μm). The instrument calculates the carbon and sulfur content by measuring the changes in infrared light absorption intensity.

[0003] Chinese utility model patent CN222913487U discloses an automatic sampler for a high-frequency infrared carbon-sulfur analyzer, which includes "a device body, a control panel connected to one side of the device body, a support leg connected to one side of the bottom of the device body, an analyzer body connected to one side of the top of the device body, a hinge connected to one side of the analyzer body, a safety door connected to one end of the hinge, a slide rail provided on one side of the device body, a motor connected to one end of the device body, a lead screw connected to one end of the motor, a moving block connected to the lead screw, an electric push rod connected to the top of the moving block, a telescopic column connected to the top of the electric push rod, a mounting base connected to the top of the telescopic column, and a crucible seat connected to the top of the mounting base";

[0004] This device uses a motor to drive a lead screw to rotate, which in turn moves the crucible into the main body of the analyzer. An electric push rod then moves the crucible into the experimental chamber to complete the automatic sample injection, thus effectively solving the problems and shortcomings of existing devices.

[0005] However, the high-frequency infrared carbon-sulfur analyzers currently used in the market all require the addition of fluxes, such as tungsten granules, pure iron, and tin granules, to lower the melting point of the sample, promote complete combustion of the sample, stabilize the electric arc, reduce interference, and ensure that carbon and sulfur elements are fully released and accurately detected. Most of the existing ones use manual addition, but manual addition of fluxes is prone to human error, has low efficiency, and is not very practical. Utility Model Content

[0006] The purpose of this invention is to provide an auxiliary feeder to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary feeder, including a frame, a feed box fixedly connected to the top surface of the frame, and an electromagnetic control valve fixedly installed on the bottom surface of the feed box;

[0008] A feeding box is fixedly connected to the front side wall of the frame, and a weighing component is movably connected inside the feeding box.

[0009] The beneficial effects of this utility model are as follows: This device is equipped with a feeding box, into which the sample and flux are respectively put into two feeding boxes. The control box controls the opening and closing of the electromagnetic control valves at the bottom of the two feeding boxes, thereby controlling the feeding of the feeding boxes. The sample and flux in the feeding box are respectively put into the weighing bowl below them by the electromagnetic control valve. The weighing bowl weighs the material in the bowl by the weighing sensor at the bottom of the bowl.

[0010] Once the set weight is reached, the rotating frame is driven by an electric motor to rotate, thereby feeding the sample from the weighing bowl into the feeding box and discharging it through the feeding outlet at the bottom of the feeding box. As the sample passes through the feeding outlet, it passes through an infrared sensor. The infrared sensor detects the sample feeding and then controls the weighing bowl containing flux to rotate, thereby feeding the flux as well, thus achieving the purpose of automatic feeding of the sample and flux.

[0011] To achieve the effect of separately controlling the feeding of sample and flux:

[0012] The further configuration is as follows: the number of the feeding boxes is two, and the two feeding boxes are arranged side by side and fixedly connected to the top surface of the frame;

[0013] Both feeding boxes have a feeding port on their top surface and a discharging port on their bottom surface. An electromagnetic control valve is fixedly installed on the bottom surface of each discharging port.

[0014] A vibration motor is fixedly installed on the bottom surface of each of the aforementioned feed boxes.

[0015] By adopting the above technical solution, two feed boxes are set up, and the sample and flux are respectively put into the two feed boxes. The feeding and use of the sample and flux are controlled by the two feed boxes respectively.

[0016] To achieve the desired effect when using sample material and flux:

[0017] The material is further configured such that: the top surface of the material box has symmetrically opened material inlets, the bottom surface of the material box has opened material outlets, and infrared sensors are symmetrically arranged on the two inner sidewalls of the material outlet.

[0018] By adopting the above technical solution, the sample material and flux in the feed box are fed into the discharge box and used. An infrared sensor is installed in the discharge outlet to monitor and sense the feeding and discharge of the material.

[0019] To achieve the effect of weighing and dispensing the sample and flux:

[0020] The weighing assembly is further configured such that: the weighing component includes a rotating frame, a weighing bowl is installed inside the rotating frame, and a weighing sensor is fixedly installed on the bottom surface of the weighing bowl;

[0021] Both sides of the rotating frame are fixedly connected to rotating shafts, and one end of the rotating shaft is connected to the output end of a drive motor fixedly installed on the side wall of the feeding box.

[0022] By adopting the above technical solution, the sample and flux in the feed box fall into the weighing component and are accurately weighed by the weighing component. The weighed material is then fed into the unloading box by rotating the rotating frame.

[0023] To achieve the effect of weighing the sample and flux separately:

[0024] The weighing components are further configured to be two in number, and the two weighing components are respectively rotatably installed in the feeding inlet on the top surface of the feeding box via the rotating shaft of their side wall.

[0025] By adopting the above technical solution, weighing components are set on both sides of the top surface of the feeding box, and the sample and flux are weighed and used separately by the two sets of weighing components.

[0026] To achieve the effect of separately weighing the sample material and flux in the two feed boxes:

[0027] The material feeding box is further configured such that it is located directly below the discharge port at the bottom of the two feeding boxes, and the material feeding inlets on both sides of the top surface of the material feeding box are respectively arranged vertically and vertically corresponding to the two electromagnetic control valves.

[0028] By adopting the above technical solution, the sample and flux in the feed boxes on both sides are respectively put into the weighing components on both sides, so as to weigh and measure the sample and flux respectively.

[0029] To achieve the effect of automatic weighing and dispensing of sample and flux:

[0030] The frame is further configured such that a control box is provided on the side wall of the frame, and the control box controls the electromagnetic control valve, the weighing sensor and the infrared sensor respectively through PLC programming.

[0031] By adopting the above technical solution, the control box, through PLC programming, receives signals transmitted by the weighing sensor and infrared sensor, and then controls the opening and closing of the electromagnetic control valve and drive motor, thereby achieving the effect of automatic weighing and feeding of sample and flux.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0040] Please see Figures 1 to 4 The auxiliary feeder includes a frame 1, a feed box 2 fixedly connected to the top surface of the frame 1, and an electromagnetic control valve 3 fixedly installed on the bottom surface of the feed box 2.

[0041] The front side wall of the frame 1 is fixedly connected to the feeding box 4, and the weighing component 5 is movably connected inside the feeding box 4.

[0042] In this embodiment, as Figure 1 and Figure 2 As shown, there are two feed boxes 2, which are arranged side by side and fixedly connected to the top surface of the frame 1;

[0043] Both feed boxes 2 have feed inlets 21 on their top surfaces and discharge outlets 22 on their bottom surfaces. Each discharge outlet 22 has an electromagnetic control valve 3 fixedly installed on its bottom surface.

[0044] A vibration motor is fixedly installed on the bottom surface of each feed box 2.

[0045] In this embodiment, as Figure 1 and Figure 3 As shown, the top surface of the feeding box 4 is symmetrically provided with a feeding inlet 41, and the bottom surface of the feeding box 4 is provided with a feeding outlet 42. Infrared sensors 6 are symmetrically arranged on the two inner side walls of the feeding outlet 42.

[0046] In this embodiment, as Figure 1 and Figure 4 As shown, the weighing assembly 5 includes a rotating frame 51, a weighing bowl 52 is installed inside the rotating frame 51, and a weighing sensor 53 is fixedly installed on the bottom surface of the weighing bowl 52.

[0047] Rotating frame 51 has two rotating shafts 54 fixedly connected to both sides of the rotating frame 51. One end of the rotating shaft 54 ​​is connected to the output end of the drive motor 55 fixedly installed on the side wall of the feeding box 4.

[0048] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, there are two weighing components 5. The two weighing components 5 are rotatably installed in the feeding inlet 41 on the top surface of the feeding box 4 through the rotating shaft 54 ​​on their side walls.

[0049] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the feeding box 4 is located directly below the discharge port 22 at the bottom of the two feeding boxes 2, and the feeding inlets 41 on both sides of the top surface of the feeding box 4 are respectively set up vertically and vertically with the two electromagnetic control valves 3.

[0050] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, a control box 11 is provided on the side wall of the frame 1. The control box 11 controls the electromagnetic control valve 3, the weighing sensor 53 and the infrared sensor 6 respectively through PLC programming.

[0051] The computer software involved in the hardware carriers such as the control box, electromagnetic control valve, weighing sensor, drive motor, and infrared sensor in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0052] Therefore, the "control box", "electromagnetic control valve", "weighing sensor", "drive motor", "infrared sensor" and other components involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the auxiliary feeding device of this application, in order to solve the corresponding technical problems to be solved by this application.

[0053] The auxiliary feeder operates as follows:

[0054] First, the sample and flux are fed into the feed boxes 2 on both sides through the feed inlet 21. The feed box 2 controls the opening and closing of the discharge port 22 through the electromagnetic control valve 3 at the discharge port 22.

[0055] The control box 11 controls the opening of the electromagnetic control valve 3, thereby feeding the sample and flux from the two feed boxes 2 into the weighing components 5 on both sides of the top surface of the lower feed box 4. The sample and flux fall into the weighing bowl 52, and the weighing sensor 53 at the bottom of the weighing bowl 52 weighs the sample and flux respectively. When the set weight is reached, the electromagnetic control valve 3 is closed, and the drive motor 55 is started to drive the rotating frame 51 to rotate in the feed inlet 41 on the top surface of the feed box 4 through the rotating shaft 54, thereby rotating the sample in the weighing bowl 52 into the feed box 4. The sample is discharged through the feed outlet 42 at the bottom of the feed box 4.

[0056] When the sample passes through the discharge outlet 42, the infrared sensor 6 detects the sample discharge. At this time, by driving the drive motor 55 of the weighing component 5 on the other side, the flux in the weighing bowl 52 is rotated and put into the discharge box 4, thus completing the discharge of the flux and achieving the effect of automatic discharge of sample and flux.

[0057] Among them, the electromagnetic control valve 3 adopts the existing known model ZBSF all-stainless steel electromagnetic valve, the weighing sensor 53 adopts the existing known model HBM C16 type, the drive motor 55 adopts the existing known model X2-100W type, and the infrared sensor 5 adopts the existing known model Panasonic EKMC4611112K type, but is not limited to the above models, all of which are known prior art.

[0058] Furthermore, the internal structure of the control box 11 and its PLC programming control system have been fully disclosed in the utility model patent (CN222913487U: an automatic sampler for a high-frequency infrared carbon-sulfur analyzer), and are mature technologies in this field. Therefore, they will not be repeated in the specification.
