Description

Technical Field

[0001] This utility model relates to the field of 3D radar level gauge technology, specifically a high-temperature 3D radar level gauge suitable for waste incinerators. Background Technology

[0002] Waste incineration technology plays a significant role in reducing, rendering harmless, and recycling waste. During waste incineration, 3D radar level gauges are often installed inside the incinerator to monitor the amount of material in real time. Radar level gauges are measuring instruments based on the time-of-flight principle. Radar waves travel at the speed of light, and the travel time can be converted into a level signal by electronic components.

[0003] A search revealed a patent with patent number 202322495728.3, entitled "Utility Model of a 3D Radar Level Gauge for Mining." The patent includes a main body, an outer ring plate, and a protective shell fixedly connected to the bottom surface of the ring plate. One end of the main body, penetrating the ring plate, is inside the protective shell. A cleaning component is slidably connected to the outer side of the protective shell and fixedly connected to the bottom surface of the ring plate. The cleaning component is used to clean dust outside the protective shell. An air supply component is provided on the bottom surface of the ring plate to blow away dust from the cleaning component.

[0004] Research and analysis revealed that this 3D radar level gauge can clean the protective shell in real time, preventing dust from adhering to it and enabling electromagnetic waves to effectively measure the material level. However, it also has some drawbacks: the introduced gas directly blows air onto the surface of the spherical protective shell for cleaning, and it is not easy to simultaneously cool the instrument base of the 3D radar level gauge while the gas is flowing. In addition, the movable plate used to clean the spherical protective shell requires a separate motor for driving, and it is not easy to use gas to retract and extend it, which is not conducive to the energy saving and cooling of the 3D radar level gauge.

[0005] The purpose of this invention is to provide a high-temperature 3D radar level gauge suitable for waste incinerators, so as to solve the problem mentioned in the background art that the use of 3D radar level gauges is not conducive to energy saving and cooling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature 3D radar level gauge suitable for waste incinerators, comprising a level gauge body, the level gauge body being composed of an instrument base, a mounting plate, and a protective shell. The instrument base is provided on the surface of the level gauge body, the mounting plate is fitted on the outer side of the instrument base, and the protective shell is fixed to the bottom of the instrument base. The protective shell has a hemispherical structure. An air intake rotation mechanism is provided on the surface of the level gauge body, the air intake rotation mechanism including a rotating component and an air intake pipe inside. A cleaning mechanism is provided on one side of the protective shell, the cleaning mechanism consisting of an air guide pipe, an arc-shaped sliding frame, a return spring, an arc-shaped sliding plate, and an elastic scraper.

[0007] Preferably, a rotating assembly is provided on the outer side of the instrument base and the protective shell, and an air intake pipe is installed on the surface of the mounting plate, the air intake pipe being connected to the rotating assembly.

[0008] Preferably, the rotating assembly includes a baffle, an annular groove, a turntable, an air blowing pipe, a spiral fan rod, and a groove. The baffle is fixed to the bottom of the mounting plate. The baffle is connected to the air inlet pipe. The baffle is sleeved on the outside of the instrument base. The central axis of the baffle coincides with the central axis of the instrument base.

[0009] Preferably, the inner wall of the baffle is provided with an annular groove, and a spiral fan rod is rotatably sleeved on the outer side of the instrument base. The spiral fan rod is rotated and engaged with the annular groove through a bracket.

[0010] Preferably, a groove is provided at the center of the bottom of the baffle, the groove is located on the outside of the protective shell, and a turntable is provided on the surface of the groove. The turntable and the baffle rotate and cooperate with each other, and the turntable is fixedly connected to the spiral fan blade rod through a connecting rod.

[0011] Preferably, an air blowing pipe is embedded circumferentially on the surface of the turntable, and one end of the air blowing pipe is located on one side of the protective shell.

[0012] Preferably, an arc-shaped sliding frame is provided on one side of the protective shell, and the surface of one side of the arc-shaped sliding frame is in close contact with the surface of the protective shell for cleaning dust adhering to the surface of the protective shell.

[0013] Preferably, an air guide pipe is fixed on one side of the top position of the arc-shaped sliding frame, the air guide pipe is connected to the arc-shaped sliding frame, and the air guide pipe is embedded in the surface of the turntable.

[0014] Preferably, an arc-shaped sliding plate is slidably disposed inside the arc-shaped sliding frame, and an elastic scraper is adhered to one side of the arc-shaped sliding plate, the surface of the elastic scraper being tightly attached to the surface of the protective shell.

[0015] Preferably, a return spring is fixed to one end of the arc-shaped slide plate, and one end of the return spring is fixedly connected to the inner wall of the arc-shaped slide frame. When the return spring is in the normal state, the arc-shaped slide plate and the elastic scraper are located inside the arc-shaped slide frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-temperature 3D radar level gauge suitable for waste incinerators is equipped with an air intake rotation mechanism and a cleaning mechanism. When it is necessary to clean the surface of the protective shell, the air intake pipe can be connected to one end of the air pump, and then air is introduced into the air intake pipe through the air pump. At this time, the air enters one side of the spiral fan rod inside the baffle, and the air pushes the spiral fan rod, causing the spiral fan rod to rotate along the annular groove under the action of the support frame, driving the turntable to rotate synchronously, and driving the cleaning mechanism to rotate around the protective shell, so that the cleaning mechanism can automatically clean the circumference of the protective shell. At the same time, the air spirals downward along the spiral fan rod. When the air flows to the bottom of the spiral fan rod, some of the air enters the air guide pipe. At this time, the air pushes the arc-shaped sliding plate, causing the arc-shaped sliding plate to rotate downward. One end of the slide plate extends out of the arc-shaped sliding frame. At this time, the elastic scraper is no longer squeezed by the arc-shaped sliding frame and, under the elastic force of its own, adheres tightly to the surface of the protective shell. Under the action of the elastic scraper and the arc-shaped sliding frame, the surface of the protective shell can be scraped and cleaned. At the same time, some air enters the air blowing pipe, blowing off the dust attached to the surface of the protective shell and the cleaning mechanism. After cleaning is completed, the air injection stops. At this time, the arc-shaped slide plate loses its thrust and resets under the action of the return spring, causing the return spring to retract into the arc-shaped sliding frame. This does not affect the use of the protective shell, so as to realize the function of the 3D radar level gauge using the incoming gas for cooling and cleaning of the protective shell surface, thereby improving the heat dissipation effect of the 3D radar level gauge during use and saving the kinetic energy required for cleaning the 3D radar level gauge.

[0020] This utility model provides a high-temperature 3D radar level gauge suitable for waste incinerators, the structure of which is as follows: Figure 1 and Figure 2 As shown, the instrument includes a level gauge body 1, which consists of an instrument base 11, a mounting plate 12, and a protective shell 13. The instrument base 11 is provided on the surface of the level gauge body 1, and the mounting plate 12 is fitted on the outer side of the instrument base 11. The protective shell 13 is fixed to the bottom of the instrument base 11, and the protective shell 13 has a hemispherical structure.

[0021] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, the surface of the level gauge body 1 is provided with an air intake rotation mechanism 2. The air intake rotation mechanism 2 includes a rotation component 21 and an air intake pipe 22 inside. The rotation component 21 is provided on the outside of the instrument base 11 and the protective shell 13. The air intake pipe 22 is installed on the surface of the mounting plate 12 and is connected to the rotation component 21. The rotation component 21 includes a baffle 211, an annular groove 212, a turntable 213, an air blowing pipe 214, a spiral fan rod 215, and a groove 216 inside. The baffle 211 is fixed to the bottom of the mounting plate 12 and is connected to the air intake pipe 22. The baffle 211 is sleeved on the outside of the instrument base 11. The central axis of the baffle 211 is... The line coincides with the central axis of the instrument base 11. The inner wall of the baffle 211 is provided with annular grooves 212. The outer side of the instrument base 11 is rotatably fitted with a spiral fan rod 215. The spiral fan rod 215 rotates and cooperates with the annular grooves 212 through the bracket. A groove 216 is provided at the center of the bottom of the baffle 211. The groove 216 is located on the outer side of the protective shell 13. A turntable 213 is covered on the surface of the groove 216. The turntable 213 rotates and cooperates with the baffle 211. The turntable 213 is fixedly connected to the spiral fan rod 215 through a connecting rod. An air blowing pipe 214 is embedded in the circumferential direction on the surface of the turntable 213. One end of the air blowing pipe 214 is located on one side of the protective shell 13.

[0022] Furthermore, such as Figure 4 As shown, a cleaning mechanism 3 is provided on one side of the protective shell 13. The cleaning mechanism 3 consists of an air guide pipe 31, an arc-shaped sliding frame 32, a return spring 33, an arc-shaped sliding plate 34, and an elastic scraper 35. The arc-shaped sliding frame 32 is provided on one side of the protective shell 13, and the surface of one side of the arc-shaped sliding frame 32 is in close contact with the surface of the protective shell 13 for cleaning dust adhering to the surface of the protective shell 13. An air guide pipe 31 is fixed to one side of the top position of the arc-shaped sliding frame 32, and the air guide pipe 31 is connected to the arc-shaped sliding frame 32. The air tube 31 is embedded in the surface of the turntable 213. An arc-shaped slide plate 34 is slidably arranged inside the arc-shaped slide frame 32. An elastic scraper 35 is glued to one side of the arc-shaped slide plate 34. The surface of the elastic scraper 35 is tightly attached to the surface of the protective shell 13. A return spring 33 is fixed to one end of the arc-shaped slide plate 34. One end of the return spring 33 is fixedly connected to the inner wall of the arc-shaped slide frame 32. When the return spring 33 is in the normal state, the arc-shaped slide plate 34 and the elastic scraper 35 are located inside the arc-shaped slide frame 32.

[0023] When cleaning the surface of the protective shell 13 is required during use, the air intake pipe 22 can be connected to one end of the air pump. Air is then introduced into the air intake pipe 22 via the air pump. At this time, the air enters one side of the spiral fan rod 215 inside the baffle 211. The air pushes the spiral fan rod 215, causing it to rotate along the annular groove 212 under the action of the support frame. This causes the turntable 213 to rotate synchronously, driving the cleaning mechanism 3 to rotate circumferentially around the protective shell 13, thus automatically cleaning the circumference of the protective shell 13. Simultaneously, the air spirals downwards along the spiral fan rod 215. When the air flows to the bottom of the spiral fan rod 215, some air enters the air guide pipe 31. At this time, the air pushes the arc-shaped sliding plate 34, causing the arc-shaped sliding plate 34 to... 4. One end extends out of the arc-shaped sliding frame 32. At this time, the elastic scraper 35 loses the pressure of the arc-shaped sliding frame 32 and adheres tightly to the surface of the protective shell 13 under its own elastic force. Under the action of the elastic scraper 35 and the arc-shaped sliding frame 32, the surface of the protective shell 13 can be scraped and cleaned. At the same time, some air enters the air blowing pipe 214 and blows off the dust attached to the surface of the protective shell 13 and the cleaning mechanism 3. After cleaning is completed, the air injection is stopped. At this time, the arc-shaped sliding plate 34 loses the thrust and resets under the action of the return spring 33, so that the return spring 33 retracts into the arc-shaped sliding frame 32. This does not affect the use of the protective shell 13, so as to realize the function of the 3D radar level gauge using the incoming gas to cool down and clean the surface of the protective shell 13.

[0024] Working principle: When in use, first install the 3D radar level gauge at the corresponding position in the waste incinerator. When working, the probe of the 3D radar level gauge emits high-frequency pulses and propagates. When the pulses encounter the surface of the waste, they will be reflected back and received by the receiver in the instrument, which will convert the distance signal into a level signal to monitor the waste level.

[0025] When cleaning the surface of the protective shell 13 is required, the air intake pipe 22 can be connected to one end of the air pump, and then air can be introduced into the air intake pipe 22 through the air pump. At this time, the air enters one side of the spiral fan rod 215 inside the baffle 211. The air pushes the spiral fan rod 215, causing it to rotate along the annular groove 212 under the action of the support frame, driving the turntable 213 to rotate synchronously, driving the cleaning mechanism 3 to rotate around the protective shell 13, so that the cleaning mechanism 3 can automatically clean the circumference of the protective shell 13. At the same time, the air spirals downward along the spiral fan rod 215. When the air flows to the bottom of the spiral fan rod 215, some of the air enters the air guide pipe 31. At this time, the air pushes the arc-shaped sliding plate 34, causing one end of the arc-shaped sliding plate 34 to extend out of the arc-shaped sliding frame 32. At this time, the elastic scraper 35 loses the squeezing of the arc-shaped sliding frame 32. The pressure, under the elastic force of the elastic scraper 35, makes it adhere tightly to the surface of the protective shell 13. Under the action of the elastic scraper 35 and the arc-shaped sliding frame 32, the surface of the protective shell 13 can be scraped and cleaned. At the same time, some air enters the air blowing pipe 214, blowing off the dust attached to the surface of the protective shell 13 and the cleaning mechanism 3. After cleaning is completed, the air injection is stopped. At this time, the arc-shaped sliding plate 34 loses its thrust and resets under the action of the return spring 33, causing the return spring 33 to retract into the arc-shaped sliding frame 32. This does not affect the use of the protective shell 13, so as to realize the function of the 3D radar level gauge using the incoming gas to cool down and clean the surface of the protective shell 13. This improves the heat dissipation effect of the 3D radar level gauge during use and saves the kinetic energy required for cleaning the 3D radar level gauge, thus completing the use of the 3D radar level gauge.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
