Description

Technical Field

[0001] This application relates to the technical field of plastic particle testing apparatus, and in particular to a dust-removable plastic particle combustion testing apparatus. Background Technology

[0002] The plastic granule combustion test apparatus is a set of instruments and equipment specifically used to conduct combustion-related tests on plastic granules in order to scientifically evaluate their combustion performance. It can simulate a variety of possible actual combustion scenarios and conditions, such as creating different flame intensities, temperatures, angles, and durations, as well as controlling the corresponding environmental parameters (such as oxygen content, ambient temperature, ventilation, etc.) to make the plastic granule sample burn in the set environment.

[0003] A search revealed Chinese patent application CN202321852385.5, which discloses a biomass pellet experimental combustion furnace. The furnace includes a base, a furnace body fixedly connected to the top of the base, a feed hopper connected to the right side of the furnace body, an igniter fixedly connected to the top of the feed hopper, and a high-temperature detector fixedly connected to the top of the furnace body. This invention adds biomass pellets to the furnace body via the feed hopper, ignites them using the igniter, and then uses a servo motor and crankshaft to drive a connecting rod upwards. This causes the connecting strip and limiting plate to move upwards within a limiting frame, opening the through-hole of the top column. This disperses or flips the biomass pellets, ensuring complete combustion. The high-temperature detector provides real-time monitoring of the combustion process data.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: after the material has been burned out, the collection of residue may require a long time for cleaning, resulting in a downtime for the machinery and thus a longer downtime for the experiment, affecting its testing efficiency. Utility Model Content

[0005] To address the problems mentioned in the background section, this application provides a dust-removable plastic particle combustion test device.

A force-bearing rod slidably fitted on the inner wall of the arc-shaped guide groove, and one end of the force-bearing rod is fixed to one side of the scraper frame.

[0007] An installation port is provided on one side of the inner wall of the test chamber, and a burner is installed on the inner wall of the installation port. An exhaust pipe is provided on the upper side of the test chamber, and a filter box is provided on the upper side of the test chamber and outside the exhaust pipe. A dust filter screen is provided on the inner wall of the filter box, and a recycling component is provided on one side of the filter box.

[0008] Optionally, the recycling assembly includes a recycling box fixedly connected to one side of the filter box, multiple heat conduction ports opened on one side of the inner wall of the filter box, heat conduction plates fixedly connected to the inner walls of the multiple heat conduction ports, a support frame slidably fitted on the inner wall of the recycling box, and multiple conduction holes opened on one side of the inner wall of the support frame.

[0009] Optionally, a discharge pipe is provided on one side of the exhaust pipe, and a dust detection filter is provided on one side of the discharge pipe.

[0010] Optionally, a guide groove is provided on one side of the inner wall of the impurity tank, and a guide plate that is fixedly connected to the cleaning frame is slidably fitted on the inner wall of the guide groove.

[0013] Optionally, a second temperature detector is provided on the upper side of the inner wall of the test chamber, and a display panel that cooperates with the first and second temperature detectors is fixedly connected to the front side of the test chamber.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] This invention incorporates components such as a cleaning frame, a scraper frame, an arc-shaped guide groove, a force-bearing rod, and a waste frame. By pulling the cleaning frame outward, the incinerated residue is expelled from its interior. The force-bearing rod, located within the arc-shaped guide groove, shifts, causing the scraper frame to scrape away debris from the inside of the cleaning frame. Impurities adsorbed within the arc-shaped guide groove are pushed into the waste frame. The waste frame can then be removed by scraping away the bottom of both the cleaning frame and the scraper frame. The waste frame is then pushed back into the cleaning frame for the next test, increasing the speed of residue removal and thus improving the efficiency of plastic experimental particle combustion.

[0016] This invention incorporates components such as an exhaust pipe, a filter box, a dust filter, and a recovery assembly. When the exhaust pipe discharges combustion smoke, the dust filter filters out dust particles from the flowing smoke. Since the smoke has a certain temperature, when it comes into contact with the heat-conducting plate, it conducts the temperature to the inside of the recovery box, thereby heating the support frame using residual heat. This preheats the materials to be processed later, simulating a combustion test under normal temperature loading conditions, improving heat recovery and utilization, and saving energy.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a dust-removable plastic particle combustion testing device. For example... Figure 1-4 As shown, the test chamber includes a test chamber 1. The lower side of the inner wall of the test chamber 1 has an impurity tank 2. The inner wall of the impurity tank 2 is slidably fitted with a waste frame 3. The inner wall of the test chamber 1 is slidably fitted with a cleaning frame 4. The inner wall of the cleaning frame 4 is slidably fitted with a scraper frame 5. An arc-shaped guide groove 6 is opened on one side of the inner wall of the test chamber 1. A force-bearing rod 7 is slidably fitted on the inner wall of the arc-shaped guide groove 6. One end of the force-bearing rod 7 is fixed to one side of the scraper frame 5.

[0024] Please see Figure 4A guide groove 16 is provided on one side of the inner wall of the impurity tank 2. A guide plate 17 that is fixedly connected to the cleaning frame 4 is slidably fitted on the inner wall of the guide groove 16. When the cleaning frame 4 is inserted and pulled out, it can be restricted by the guide plate 17 sliding in the guide groove 16.

[0025] Please see Figure 1 The upper side of the cleaning frame 4 is provided with a feeding port 18. Both the waste frame 3 and the cleaning frame 4 are fixedly connected to a handle 19. The feeding port 18 can be set at an angle. By feeding material into the feeding port 18, the material can be guided. The handle 19 can facilitate the control of the waste frame 3 and the cleaning frame 4. The handle 19 can facilitate the exertion of force by personnel. When operating the handle 19, personnel must wear heat-resistant gloves.

[0026] An installation port 8 is provided on one side of the inner wall of the test chamber 1. A burner 9 is provided on the inner wall of the installation port 8. An exhaust pipe 10 is provided on the upper side of the test chamber 1. A filter box 11 is provided on the upper side of the test chamber 1 and outside the exhaust pipe 10. A dust filter screen 12 is provided on the inner wall of the filter box 11. A recycling component 13 is provided on one side of the filter box 11.

[0027] Please see Figure 4 The recycling assembly 13 includes a recycling box 131 fixedly connected to one side of the filter box 11, multiple heat conduction ports 132 opened on one side of the inner wall of the filter box 11, a heat conduction plate 133 fixedly connected to the inner wall of the multiple heat conduction ports 132, a support frame 134 slidably fitted on the inner wall of the recycling box 131, and multiple conduction holes 135 opened on one side of the inner wall of the support frame 134. During use, since the smoke has a certain temperature, when it comes into contact with the heat conduction plate 133, it will conduct the temperature to the inside of the recycling box 131, thereby heating the support frame 134 with residual heat, which can preheat the materials to be processed later. It can simulate the combustion test under normal temperature filling, improve the recovery and utilization of heat, and save energy.

[0028] Please see Figure 1 A detection port 20 is provided on the upper side of the inner wall of the recycling bin 131. A first temperature detector 21 is fixedly connected to the inner wall of the detection port 20. The heat in the recycling bin 131 can be detected through the first temperature detector 21.

[0029] Please see Figure 4A discharge pipe 14 is provided on one side of the exhaust pipe 10, and a smoke and dust detection filter 15 is provided on one side of the discharge pipe 14. The discharge pipe 14 is used to discharge smoke and dust. The smoke and dust detection filter 15 is a device that filters smoke and dust during the detection process to achieve a specific detection purpose or to ensure the normal operation of the detection equipment and improve the detection accuracy. It may be equipped with a sensor to first detect the flowing gas to detect the smoke and dust situation, and then filter it through the corresponding electrostatic adsorption principle to ensure that the discharged air quality is relatively clean.

[0030] Please see Figure 1 A second temperature detector 22 is provided on the upper side of the inner wall of the test chamber 1. A display panel 23 that cooperates with the first temperature detector 21 and the second temperature detector 22 is fixedly connected to the front side of the test chamber 1. The display panel 23 is used to display the temperature of the first temperature detector 21 and the second temperature detector 22. The first temperature detector 21 can detect the inside of the test chamber 1.

[0031] The implementation principle of the dust-removable plastic granule combustion test device in this application embodiment is as follows: when testing is required, the test chamber 1 is used, and the plastic granules to be tested are poured into the inside of the feeding port 18. Then the cabinet door is closed, and the granules inside the installation port 8 are burned by the burner 9 inside the installation port 8 for a certain period of time. The burning residue is then removed to observe the combustion situation.

[0032] When cleaning is required after combustion, first open the cabinet door. Pulling the cleaning frame 4 outward will bring out the incinerated residue. The force rod 7 is displaced inside the arc-shaped guide groove 6, causing the scraper frame 5 to scrape the inside of the cleaning frame 4. The impurities adsorbed inside the arc-shaped guide groove 6 are pushed into the waste frame 3. By pulling out the waste frame 3, the bottom of the cleaning frame 4 and the scraper frame 5 can be scraped and removed. Then, the cleaning frame 4 is pushed in for the next test, which increases the speed of removing residue and thus improves the efficiency of plastic experimental particle combustion.

[0033] During use, the smoke from combustion is discharged through the exhaust pipe 10, and the dust filter 12 can filter the dust in the flowing smoke. Since the smoke has a certain temperature, when it comes into contact with the heat conduction plate 133, it will conduct the temperature to the inside of the recovery box 131, and then use the residual heat to heat the support frame 134, so as to preheat the materials to be processed later, in order to simulate the combustion test under normal temperature conditions, improve the recovery and utilization of heat, and save energy.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
