Description

Technical Field

[0001] This application relates to solid waste leaching toxicity detection technology, and more particularly to a flip-type oscillator for solid waste detection. Background Technology

[0002] The flip-type oscillator is a device specified in the national environmental protection industry standard, and is suitable for the leaching toxicity detection of inorganic pollutants and volatile or semi-volatile organic pollutants in solid waste.

[0003] Existing tilting oscillators operate in a sealed environment with the tilting cylinder inside a shroud. When heating is required, hot air is blown into the shroud to provide heat and control the temperature of the sample inside the tilting cylinder.

[0004] The existing tilting oscillator, which uses hot air heating, has its drawbacks. The heat in the hot air is lost quickly during the flow process, and the heat exchange effect is different on the windward and leeward sides, resulting in uneven heating of the sample inside the tilting cylinder. Utility Model Content

[0005] This application provides a flip-type oscillator for solid waste testing, which solves the problem of uneven heating in existing flip-type oscillators.

[0006] This application provides a flip-type vibrator for solid waste detection, including a fixed frame with a rotating shaft that rotates laterally on the fixed frame. Multiple flip-type cylinders, each consisting of a cylinder body and a cover, are vertically fixed on the rotating shaft. The rotating shaft is rotated by a drive mechanism installed at one end. The rotating shaft is a hollow pipe with a sleeve inserted inside its walls, the sleeve and the pipe serving as the rotating shaft being connected to an inlet pipe and an outlet pipe, respectively. The inlet pipe is connected to the upper end of the flip-type cylinder body, and the outlet pipe is connected to the lower end of the flip-type cylinder body. The ends of the rotating shaft and the sleeve are rotatably connected to the water inlet and return outlet of a water bath heater, respectively.

[0007] Optionally, the rotating shaft and the sleeve are rotatably connected to the water bath heater via a connecting pipe. The connecting pipe has a partition fixed inside to divide it into two independent chambers. The end of the rotating shaft is inserted into the connecting pipe and rotatably connected to the chamber on one side of the partition. The end of the sleeve passes through the partition and rotatably connects to the chamber on the other side. The water inlet and outlet of the water bath heater are respectively connected to the two chambers of the connecting pipe.

[0008] Optionally, the sleeve is connected to the inlet pipe, the pipe serving as the rotating shaft is connected to the outlet pipe, the water inlet of the water bath heater is connected to the sleeve, and the return outlet is connected to the pipe serving as the rotating shaft.

[0009] Optionally, a hollow water storage cavity is formed inside the side wall of the tilting cylinder, and the water inlet pipe and water outlet pipe are connected to the water storage cavity.

[0010] Optionally, the bottom of the cylinder and the inside of the cylinder cover of the flipping cylinder are provided with a limiting plate that slides up and down, and a spring is fixed between the limiting plate and the cylinder wall.

[0011] Compared with the prior art, the advantages of the flip-type oscillator for solid waste detection provided in this application are:

[0012] A hollow pipe is used as the rotating shaft, and a sleeve is installed inside the pipe serving as the rotating shaft. The pipe serving as the rotating shaft and the sleeve can be connected to the tilting cylinder, allowing the water bath heater to inject water into the tilting cylinder through the sleeve and circulate it back through the pipe of the rotating shaft.

[0013] The drive mechanism rotates the shaft, causing the tilting cylinder to vibrate the sample in the test bottle. At the same time, the water bath heater injects and circulates water into the tilting cylinder through the sleeve and shaft, which can complete the water bath heating operation of the sample in the tilting cylinder without affecting the tilting of the cylinder.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0025] like Figures 1-5 As shown, one embodiment of this application provides a flip-type vibrator for solid waste detection, including a fixed frame 1, a rotating shaft 2 that rotates laterally on the fixed frame 1, and multiple flip-type cylinders 3 composed of cylinder bodies and cylinder covers that are vertically fixed on the rotating shaft 2. The rotating shaft 2 is rotated by a drive mechanism 4 installed at one end. The rotating shaft 2 is a hollow pipe, and a sleeve 7 with a gap between the pipe walls is inserted into the pipe. The sleeve 7 and the pipe that serves as the rotating shaft 2 are respectively connected to an inlet pipe 5 and an outlet pipe 6. The inlet pipe 5 is connected to the upper end of the cylinder body of the flip-type cylinder 3, and the outlet pipe 6 is connected to the lower end of the cylinder body of the flip-type cylinder 3. The ends of the rotating shaft 2 and the sleeve 7 are respectively rotatably connected to the water inlet and the water outlet of a water bath heater 8.

[0026] When using, put the sample into the test bottle and seal it. Open the cap of the flip cylinder 3, put the test bottle containing the sample into the cylinder, and close the cap of the flip cylinder 3 and seal it.

[0027] The rotating shaft 2 is driven by the drive mechanism 4 to rotate, causing the tilting cylinder 3 to tilt. At the same time, the water bath heater 8 injects hot water from the water inlet through the sleeve 7 and the water inlet pipe 5 into the tilting cylinder 3. After the hot water heats the sample in the test bottle in the tilting cylinder 3, it flows back to the water bath heater 8 through the water outlet pipe 6 from the pipe that serves as the rotating shaft 2 through the water return port for circulating heating.

[0028] In this embodiment, a hollow pipe is used as the rotating shaft 2, and a sleeve 7 is installed inside the pipe serving as the rotating shaft 2. The pipe serving as the rotating shaft 2 and the sleeve 7 can be connected to the tilting cylinder 3 respectively, so that the water bath heater 8 can inject water into the tilting cylinder 3 through the sleeve 7 and circulate it back through the pipe of the rotating shaft 2.

[0029] While the drive mechanism 4 rotates the rotating shaft 2 to drive the flipping cylinder 3 to oscillate the sample in the test bottle, the water bath heater 8 injects water into the flipping cylinder 3 through the sleeve 7 and the rotating shaft 2 and circulates it. This allows the water bath heating of the sample in the flipping cylinder 3 to be completed without affecting the flipping of the flipping cylinder 3.

[0030] like Figure 6 As shown, in one possible implementation, the rotating shaft 2 and the sleeve 7 are rotatably connected to the water bath heater 8 via a connector 9. The connector 9 has a partition 10 fixed inside to divide it into two independent chambers. The end of the rotating shaft 2 is inserted into the connector 9 and rotatably connected to the chamber on one side of the partition 10. The end of the sleeve 7 passes through the partition 10 and rotatably connects to the chamber on the other side. The water inlet and outlet of the water bath heater 8 are respectively connected to the two chambers of the connector 9.

[0031] The pipe and sleeve 7, which serve as the pivot 2, are connected to the chambers on both sides of the inner partition 10 of the connector 9 and are rotatably connected. The chambers on both sides of the inner partition 10 of the connector 9 are connected to the water inlet and water outlet of the water bath heater 8, respectively. The hot water exchanged by the water bath heater 8 circulates through the two chambers, flowing out and returning.

[0032] In one possible implementation, the sleeve 7 is connected to the inlet pipe 5, the pipe serving as the rotating shaft 2 is connected to the outlet pipe 6, the water inlet of the water bath heater 8 is connected to the sleeve 7, and the return outlet is connected to the pipe serving as the rotating shaft 2.

[0033] The sleeve 7 is located inside the pipe that serves as the pivot 2. The sleeve 7 is connected to the inlet pipe 5, and the pipe that serves as the pivot 2 is connected to the outlet pipe 6. This allows the return water to wrap around the injected hot water, forming an insulation layer and preventing the hot water from cooling down inside the pipe during its flow.

[0034] like Figure 7 As shown, in one possible implementation, a hollow water storage cavity 11 is formed inside the side wall of the rotating cylinder 3, and the water inlet pipe 5 and the water outlet pipe 6 are connected to the water storage cavity 11.

[0035] A water storage chamber 11 is provided inside the side wall of the rotating cylinder 3, so that the hot water for heat exchange flows in the water storage chamber 11 to heat the sample water bath in the test bottle, which can avoid direct contact between the hot water for heat exchange and the test bottle.

[0036] In one possible implementation, the bottom of the cylinder body and the inside of the cylinder cover of the flipping cylinder 3 are provided with a limiting plate 12 that slides up and down, and a spring 13 is fixed between the limiting plate 12 and the cylinder wall.

[0037] After the test bottle is placed into the cylinder of the flipping cylinder 3, the cylinder cover of the flipping cylinder 3 is closed, and the test bottle can be fixed by the spring 13 pressing the limiting plate 12 from the upper and lower ends.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
