Description

Technical Field

[0001] This utility model relates to the field of coal content detection technology, and more specifically, to a flushing device for a coal content detection system. Background Technology

[0002] Coal carbon content testing refers to the process of quantitatively analyzing the content of various components (such as fixed carbon, volatile matter, ash, and moisture) in coal through a series of physical and chemical methods. The content of these components directly determines the calorific value, combustion characteristics, and uses of coal, and is a core indicator for evaluating coal quality. Accurate coal carbon content testing is of great significance for guiding the rational mining, processing, utilization, market transactions, and environmental protection of coal. By understanding the content of each component in coal, its combustion performance, calorific value, and applicable scenarios can be determined, thereby helping relevant enterprises and institutions make more scientific and rational decisions.

[0003] In coal content testing, samples are typically placed in a special container for analysis. After testing, coal dust or sludge often remains on the inner wall of the container. Existing cleaning methods mostly rely on manual operation, which is inefficient, time-consuming, and fails to thoroughly clean the container, affecting subsequent test results. Therefore, there is an urgent need for a rinsing device for coal content testing systems to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing systems, the purpose of this invention is to provide a rinsing device for a coal content detection system. This device can quickly rinse the coal content detection container, rapidly remove residues from the inner wall of the coal container, and achieve immediate drying through a hot air circulation system, ensuring the cleanliness of the container and the accuracy of the detection results.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A flushing device for a coal content detection system includes a wastewater collection tank and a fine-mesh filter plate. The fine-mesh filter plate, with a U-shaped structure, is fixedly installed at the bottom of the wastewater collection tank and is inclined towards the center. A removable slag storage tray is placed inside the fine-mesh filter plate. A drain pipe for discharging wastewater is fixedly installed at the bottom rear side of the wastewater collection tank. A support column is fixed to the upper side of the wastewater collection tank via multiple sets of fixed brackets. An annular water pipe is fixed to the outside of the support column via a support frame. Multiple spray nozzles for spray rinsing are provided on the upper surface of the annular water pipe. A water inlet pipe is connected to the right side of the annular water pipe. A solenoid valve is installed on the water inlet pipe, and the water inlet pipe is connected to an external tap water pipe. A waterproof pressure switch is installed at the upper end of the support column.

[0007] Furthermore, the nozzle has an inclined structure with an inclination angle of 60 degrees, and the inclination angles of two adjacent sets of nozzles are opposite, with one set inclined towards the inside of the annular water pipe and the other set inclined towards the outside of the annular water pipe.

[0008] Furthermore, multiple sets of L-shaped positioning rods are fixed on the support ring surface, and the positioning rods are located on the lower side of the annular water pipe. An airbag head is fixed at the upper end of the positioning rod, and the upper surface of the airbag head is flush with the upper surface of the waterproof pressure switch.

[0009] Furthermore, an annular air duct is provided on the outside of the support column, and the annular air duct is fixed on the support frame. Multiple sets of air nozzles are evenly provided on the upper side of the annular air duct. An air pipe is connected to the bottom of the annular air duct. The outer end of the air pipe is connected to an electric heater installed on the right side of the wastewater collection tank. An air pump is provided on the lower side of the electric heater. The output end of the air pump is connected to the electric heater through the air duct.

[0010] Furthermore, a transparent PVC panel is fixed to the upper end of the wastewater collection tank, and the upper end of the transparent panel is higher than the upper end of the support column.

[0011] Furthermore, a material inlet is provided on the front end face of the wastewater collection tank, and the width and height of the material inlet are greater than the width and height of the slag storage tray. A detachable sealing cover is fitted on the outside of the material inlet.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model can quickly rinse the coal content testing container, quickly remove the residue on the inner wall of the coal container, and achieve instant drying through a hot air circulation system, ensuring the cleanliness of the container and the accuracy of the test results.

[0014] 2. This utility model utilizes an inclined nozzle design to create a specific angle and force in the water jet, better covering and rinsing the surface of the coal content testing container. Adjacent sets of nozzles are designed with opposite inclination angles: one set tilts inwards towards the inside of the annular water pipe, and the other tilts outwards. This alternating arrangement ensures a staggered spray pattern during rinsing, resulting in more even coverage of the container's surface. This inclined and alternating nozzle design allows the water jet to impact the container surface at different angles and forces, effectively removing coal slag and dirt adhering to the container. This rinsing method not only improves cleaning efficiency but also ensures thorough cleaning, guaranteeing a clean and residue-free container surface.

[0015] 3. In this utility model, multiple sets of L-shaped positioning rods are fixed on the support ring surface, and the positioning rods are located on the lower side of the annular water pipe. This not only provides stable support for the coal content detection container but also ensures accurate positioning of the container during rinsing, guaranteeing the stability of the coal content detection container. An airbag pad is fixed at the upper end of the positioning rod, and the upper surface of the airbag pad is flush with the upper surface of the waterproof pressure switch. The airbag pad has soft and compressible characteristics, allowing it to make close contact with the bottom of the coal content detection container, providing an anti-slip function without damaging the container. The upper surface of the airbag pad is flush with the upper surface of the waterproof pressure switch. This design ensures that when the coal content detection container is placed on the positioning rod, the bottom of the container presses against the airbag pad, thereby triggering the waterproof pressure switch.

[0016] 4. This utility model, through the design of annular air duct and multiple sets of air nozzles, can quickly dry the container after cleaning, avoiding the influence of residual moisture on subsequent test results. After the cleaning process is completed, the air pump starts, draws in gas and delivers it to the electric heater through the air duct for heating. The heated air then enters the annular air duct through the air duct and is evenly blown onto the surface of the container from the air nozzles, achieving rapid and effective drying.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] Example:

[0024] like Figures 1 to 4 As shown, a flushing device for a coal content detection system includes a wastewater collection tank 2 and a fine-mesh filter plate 11. The fine-mesh filter plate 11 with a U-shaped structure is fixed at the bottom of the wastewater collection tank 2, and the fine-mesh filter plate 11 is inclined towards the center. The fine-mesh filter plate 11 helps to effectively separate coal slag and wastewater, allowing the coal slag to slide down to the central slag storage tray 12 due to gravity, thus achieving coal slag collection. A removable slag storage tray 12 is placed inside the fine-mesh filter plate 11. The slag storage tray 12 is removable for easy cleaning of the coal slag. A drain pipe 9 for discharging wastewater is fixed at the bottom rear side of the wastewater collection tank 2. Multiple sets of fixed supports 1 are used to connect the upper side of the wastewater collection tank 2. 3. A support column 14 is fixed, and an annular water pipe 19 is fixed to the outside of the support column 14 through a support frame 20. Multiple sets of spray nozzles 18 for spray rinsing are provided on the upper side of the annular water pipe 19. The multiple sets of spray nozzles 18 arranged in an annular shape ensure that the rinsing water evenly covers the entire cleaning area, thereby improving the cleaning efficiency. A water inlet pipe 4 is connected to the right side of the annular water pipe 19. A solenoid valve 5 is installed on the water inlet pipe 4, and the water inlet pipe 4 is connected to an external tap water pipe. A waterproof pressure switch 15 is installed at the upper end of the support column 14. This design solves the problem that the existing coal content detection container cleaning method relies on manual operation, which is low efficiency, time-consuming and difficult to thoroughly clean, thus affecting the subsequent test results.

[0025] In this embodiment, the nozzle 18 has an inclined structure with an inclination angle of 60 degrees. Adjacent sets of nozzles 18 have opposite inclination angles; one set is inclined inwards towards the annular water pipe 19, and the other set is inclined outwards. This inclined design allows the sprayed water to form a specific angle and force, better covering and rinsing the surface of the coal content detection container. Furthermore, the alternating arrangement of adjacent sets of nozzles 18 ensures that the water flow forms a staggered spray pattern during rinsing, thus more evenly covering the various surfaces of the container. This inclined and alternating nozzle design allows the water flow to impact the container surface at different angles and forces, effectively removing coal slag and dirt adhering to the container. This rinsing method not only improves cleaning efficiency but also ensures thorough cleaning, guaranteeing a clean and residue-free container surface.

[0026] In this embodiment, multiple sets of L-shaped positioning support rods 17 are fixed on the annular surface of the support column 14, and the positioning support rods 17 are located below the annular water pipe 19. This not only provides stable support for the coal content detection container, but also ensures the accurate positioning of the container during the rinsing process, thus guaranteeing the stability of the coal content detection container. An airbag pad 16 is fixed at the upper end of the positioning support rod 17, and the upper surface of the airbag pad 16 is flush with the upper surface of the waterproof pressure switch 15. The airbag pad 16 has soft and compressible characteristics, which allows it to make close contact with the bottom of the coal content detection container, playing a role in preventing slippage without damaging the container. The upper surface of the airbag pad 16 is flush with the upper surface of the waterproof pressure switch 15. This design ensures that when the coal content detection container is placed on the positioning support rod 17, the bottom of the container will press against the airbag pad 16, thereby triggering the waterproof pressure switch 15.

[0027] In this embodiment, an annular air duct 21 is provided on the outer side of the support column 14 and is fixed on the support frame 20. Multiple sets of air nozzles 22 are evenly arranged on the upper side of the annular air duct 21. An air pipe 23 is connected to the bottom of the annular air duct 21, and the outer end of the air pipe 23 is connected to an electric heater 8 installed on the right side of the wastewater collection tank 2. An air pump 6 is provided on the lower side of the electric heater 8, and the output end of the air pump 6 is connected to the electric heater 8 through an air duct 7. Through the design of the annular air duct 21 and multiple sets of air nozzles 22, the container can be quickly dried after cleaning, avoiding the influence of residual moisture on subsequent test results. After the cleaning process is completed, the air pump 6 is started, drawing in gas and delivering it to the electric heater 8 through the air duct 7 for heating. The heated hot air enters the annular air duct 21 through the air pipe 23 and is evenly blown onto the surface of the container from the air nozzles 22, achieving rapid and effective drying.

[0028] In this embodiment, a transparent PVC panel 1 is fixed to the upper end of the wastewater collection tank 2, and the upper height of the transparent panel 1 is greater than the upper height of the support column 14. The transparent panel 1 can block the upper area of ​​the wastewater collection tank 2, preventing water from splashing out during washing.

[0029] In this embodiment, a material retrieval slot 10 is provided on the front end face of the wastewater collection tank 2, and the width and height of the material retrieval slot 10 are greater than the width and height of the slag storage tray 12. A detachable sealing cover 3 is fitted on the outside of the material retrieval slot 10. The material retrieval slot 10 is used to remove the slag storage tray 12 from the wastewater collection tank 2, which facilitates the cleaning of the slag storage tray 12. At the same time, the sealing cover 3 can seal the slot to prevent wastewater from splashing out, and this cover is detachable, making it easy to open when material needs to be retrieved.

[0030] The working principle of a flushing device used in a coal content detection system:

[0031] In actual use, the coal content detection container is placed upside down on the positioning support rod 17, ensuring that the bottom of the container presses against the airbag head 16, thereby triggering the waterproof pressure switch 15. The waterproof pressure switch 15 opens the solenoid valve 5, allowing external tap water to enter the annular water pipe 19, and the nozzles 18 begin spraying rinsing water. The device has an annular water pipe 19 inside, with multiple sets of tilted nozzles 18 mounted on the upper side of the pipe. The tilt angle is 60 degrees, and adjacent sets of nozzles 18 have opposite tilt angles, forming an alternating spray pattern that evenly covers the entire surface of the coal content detection container, effectively removing coal slag and dirt. During the cleaning process, wastewater flows through the fine-mesh filter plate 11 into the bottom of the wastewater collection tank 2 and is discharged through the drain pipe 9. Coal slag slides down to the central slag storage tray 12 due to gravity, achieving coal slag collection. After cleaning, the air pump 6 starts, drawing gas into the electric heater 8 for heating. The heated hot air enters the annular air duct 21 through the air pipe 23 and is evenly blown onto the container surface from the air nozzle 22, achieving rapid and effective drying. After drying, turn off the power to the device and remove the coal content detection container. Remove the slag storage pan 12 through the material inlet 10, clean the slag, and return the slag storage pan 12 to its original position.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
