Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically to a fuel additive detection and sampling device. Background Technology

[0002] Fuel additives are categorized into gasoline additives and diesel additives based on their intended use, and generally fall into three functional categories: cleaning additives, maintenance additives, and power-enhancing additives. Cleaning and maintenance additives contain cleaning agents in their chemical composition, effectively cleaning or inhibiting the formation of carbon deposits in the engine. Fuel additives undergo sampling and testing during production.

[0003] A search revealed existing technology (publication number: CN219511883U), which describes "a high-efficiency sampling device for detecting liquid food additives, comprising a bracket and a indexing device fixed to a workbench. A lifting cylinder is fixed to the bottom surface of the mounting plate, and a suction pipe extending downward through the mounting plate is fixed to the lifting plate. An annular plate is welded to the outer wall of the lower end of the suction pipe, and a columnar filter cylinder is fixed to the outside of the annular plate, with the bottom of the filter cylinder sealed. A vertically arranged liquid outlet pipe is fixed to the left side wall of the bracket, and a liquid outlet nozzle is fixed to the bottom of the liquid outlet pipe. A metering pump is connected between the top end of the liquid outlet pipe and the top end of the suction pipe. The indexing device includes a stepper motor fixed to the workbench surface and located on the right side of the bracket, with a turntable mounted on the output shaft of the stepper motor. The beneficial effects of this utility model are: compact structure, greatly improved efficiency of liquid food sampling, and reduced sampling workload."

[0004] While existing high-efficiency sampling devices for additive detection have improved sampling efficiency, they still have some shortcomings: Firstly, existing high-efficiency sampling devices for additive detection cannot clean the sampling tube after each sampling, leading to interference from residual liquid on the inner wall of the sampling tube when sampling multiple samples. Secondly, the rotating plate speed cannot be too fast, otherwise the liquid in the container will splash out during the transition from a standstill to a momentary start-up, resulting in lower continuous detection efficiency. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, a fuel additive detection and sampling device is provided to solve the problems mentioned in the background.

[0006] To achieve the above objectives, a fuel additive detection and sampling device is provided, comprising: a base, a column at the upper end of the base, a top plate at the upper end of the column, a raw material tray and a receiving tray on the upper side of the base and in front of the column, a motor connected to the lower side of the raw material tray via a gear set, a raw material cup and a cleaning cup at the upper end of the raw material tray, a receiving cup and a waste cup at the upper side of the receiving tray, and a synchronous belt connecting the receiving tray and the raw material tray; a metering pump and an electric hot air blower installed on the upper side of the top plate, with an inlet pipe and an outlet pipe connected to both ends of the metering pump, the inlet pipe located above the raw material tray and the outlet pipe located above the receiving tray; and the outlet end of the electric hot air blower connected to the inlet pipe and the outlet pipe via an outlet pipe and a cross-connector, respectively.

[0007] Furthermore, the raw material cup and the washing cup are alternately arranged in the circumferential direction of the raw material tray, while the receiving cup and the waste cup are alternately arranged in the circumferential direction of the receiving tray.

[0008] Furthermore, the lower end of the raw material tray is connected to a first rotating shaft, and the lower end of the receiving tray is connected to a second rotating shaft. Both the outer sides of the first and second rotating shafts are connected to synchronous pulleys, and a synchronous belt is connected between the two synchronous pulleys.

[0009] Furthermore, the raw material cup includes an outer cup wall, and an anti-splash funnel is provided on the inner side of the cup wall, with a locking block provided at the upper edge of the anti-splash funnel.

[0010] Furthermore, the inner side of the cup wall is provided with a cup cavity, and the upper end of the cup wall is provided with a slot that matches and engages with the card block.

[0011] Furthermore, a hydraulic rod is installed at the lower end of the top plate and on the front side of the column, and a lifting plate is connected to the lower end of the hydraulic rod. The lower end of the lifting plate is connected to a liquid extraction pipe and a liquid discharge pipe. At the same time, the liquid extraction pipe and the liquid discharge pipe are connected to the lower ends of the liquid inlet pipe and the liquid outlet pipe respectively through flexible hoses.

[0012] Furthermore, a guide rod is connected to the upper side of the outer end of the lifting plate, and the guide rod slides through the top plate. A proximity switch is installed on the lower side of the lifting plate and on the front side wall of the column. The proximity switch is electrically connected to the hydraulic rod through an external controller.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Using a raw material tray, different types of additive raw materials are first poured into the raw material cups. Then, the motor is started, and through the gear set and the first rotating shaft, one of the raw material cups on the tray is rotated to the underside of the extraction tube. Then, the hydraulic rod is started, and through the lifting plate, the extraction tube is inserted downward into the raw material cup. Then, the metering pump is started to pump the raw materials into the receiving cup, thus completing the sequential sampling. Then, the extraction tube is reset, and the discharge tube is reset simultaneously. Then, the motor is started again to drive the raw material tray to rotate at a set angle. At this time, the cleaning cup is placed under the extraction tube, and the extraction process is repeated, so that the cleaning agent in the cleaning cup is pumped into the pipeline and then discharged from the discharge tube into the waste cup, thus cleaning the pipeline of the previous residual raw materials. Then, the electric hot air fan is started to dry the extraction pipeline through the air outlet pipe and the cross pipe, so that the next type of additive can be sampled. This avoids mutual interference between different types of fuel additives during the sampling process and ensures accurate test results.

[0015] 2. Utilizing the cup wall and chamber of the raw material cup, the raw material enters the cup cavity through the anti-splash funnel. Because the anti-splash funnel is wider at the top and narrower at the bottom, it can prevent the internal additive raw materials from splashing out due to inertia when the raw material tray rotates rapidly, thereby increasing the rotation speed of the raw material tray and further improving the sampling efficiency. When cleaning the residual additive raw materials in the raw material cup, the anti-splash funnel can be removed through the locking block and slot, and then the residual additive raw materials can be cleaned by removing the raw material cup.

Detailed Implementation

[0022] Reference Figures 1 to 5 As shown, this utility model provides a fuel additive detection and sampling device, including: a base 1, a column 11 at the upper end of the base 1, a top plate 12 at the upper end of the column 11, a raw material tray 2 and a receiving tray 3 on the upper side of the base 1 and in front of the column 11, a motor 14 connected to the lower side of the raw material tray 2 via a gear set 16, a raw material cup 21 and a cleaning cup 22 at the upper end of the raw material tray 2, a receiving cup 31 and a waste cup 32 at the upper side of the receiving tray 3, and a synchronous belt 15 connecting the receiving tray 3 and the raw material tray 2, a metering pump 4 and an electric hot air blower 6 installed on the upper side of the top plate 12, and an inlet pipe 41 and an outlet pipe 42 connected to the two ends of the metering pump 4 respectively, with the inlet pipe 41 located on the upper side of the raw material tray 2 and the outlet pipe 42 located on the upper side of the receiving tray 3, and the air outlet of the electric hot air blower 6 connected to the inlet pipe 41 and the outlet pipe 42 respectively via an air outlet pipe 61 and a cross-connection pipe 62.

[0023] In this embodiment, the base 1, raw material tray 2, receiving tray 3, metering pump 4, hydraulic rod 5, and electric hot air blower 6 constitute the main structure of the fuel additive detection and sampling device involved in this application.

[0024] The cleaning cup 22 contains a cleaning agent, which can be alcohol in this application. The receiving cup 31 is a sampling vessel to facilitate the preservation of the sample after sampling for subsequent testing.

[0025] Specifically, the upper end of the inlet pipe 41 is connected to the inlet end of the metering pump 4, and the outlet pipe 42 is connected to the outlet end of the metering pump 4. Both the inlet pipe 41 and the outlet pipe 42 pass through the top plate 12.

[0026] Among them, the connection between the inlet pipe 41 and the outlet pipe 42 and the cross-connection pipe 62 is equipped with an electromagnetic valve, and the electromagnetic valve is in the closed state when the liquid is being drawn for sampling.

[0027] like Figures 1 to 5In the process, the raw material cup 21 and the washing cup 22 are alternately arranged in the circumferential direction of the raw material tray 2, while the receiving cup 31 and the waste cup 32 are alternately arranged in the circumferential direction of the receiving tray 3. The lower end of the raw material tray 2 is connected to the first rotating shaft 23, and the lower end of the receiving tray 3 is connected to the second rotating shaft 33. The outer sides of the first rotating shaft 23 and the second rotating shaft 33 are both connected to synchronous pulleys, and the synchronous belt 15 is connected between the two synchronous pulleys. The raw material cup 21 includes an outer cup wall 211, and the inner side of the cup wall 211 is provided with a splash shield 212. The upper edge of the splash shield 212 is provided with a locking block 213. The inner side of the cup wall 211 is provided with a cup cavity 214, and the upper edge of the cup wall 211 is provided with a locking groove that matches and engages with the locking block 213.

[0028] Specifically, in the initial state, when the raw material cup 21 is under the liquid extraction tube 44, the receiving cup 31 is under the discharge tube 45. Then, through the synchronous belt 15 and the synchronous pulley, after the next rotation, the cleaning cup 22 is under the liquid extraction tube 44 and the waste cup 32 is under the discharge tube 45, so as to collect the waste liquid after cleaning. Secondly, the lower ends of the liquid extraction tube 44 and the discharge tube 45 are extended to be located on the rotation path of the center point of all cups on the raw material plate 2 and the receiving plate 3, respectively.

[0029] Among them, the synchronous belt 15 is a toothed belt, which works with the synchronous pulley to realize the synchronous rotation of the first rotating shaft 23 and the second rotating shaft 33.

[0030] Specifically, the gear set 16 includes a gear mounted on the outside of the first rotating shaft 23 and a gear mounted on the output shaft end of the motor 14, and the two gears mesh and drive each other.

[0031] Specifically, the bottom diameter of the anti-splash bucket 212 is larger than the outer diameter of the liquid extraction tube 44, and there is a gap between the bottom of the anti-splash bucket 212 and the bottom of the inner wall of the cup 211.

[0032] It should be noted that the cleaning cup 22, the receiving cup 31, and the waste cup 32 can all adopt the anti-splash bucket 212 structure.

[0033] like Figure 1 In the middle, a hydraulic rod 5 is installed at the lower end of the top plate 12 and in front of the column 11. The lower end of the hydraulic rod 5 is connected to a lifting plate 51, and the lower end of the lifting plate 51 is connected to a suction pipe 44 and a discharge pipe 45. At the same time, the suction pipe 44 and the discharge pipe 45 are connected to the lower ends of the inlet pipe 41 and the outlet pipe 42 respectively through a hose 43. A guide rod 52 is connected to the upper side of the outer end of the lifting plate 51, and the guide rod 52 slides through the top plate 12. A proximity switch 13 is installed on the lower side of the lifting plate 51 and on the front side wall of the column 11. The proximity switch 13 is electrically connected to the hydraulic rod 5 through an external controller.

[0034] As a preferred implementation, by setting a proximity switch 13 electrically connected to the hydraulic rod 5, it is possible to control the depth of the liquid extraction tube 44 inserted into the raw material cup 21 when the hydraulic rod 5 drives the lifting plate 51 to move downward. Secondly, the setting of the guide rod 52 enhances the motion guidance of the lifting plate 51.

[0035] In use, first pour the different types of additive raw materials into the raw material cups, place the alcohol cleaning agent in the cleaning cup, then start the motor to rotate one of the raw material cups on the raw material tray to the underside of the extraction tube via the gear set and the first rotating shaft. Then, start the hydraulic rod to insert the extraction tube downwards into the raw material cup via the lifting plate. Then, start the metering pump to pump the raw materials into the receiving cup, thus completing the sequential sampling. Then, reset the extraction tube, and at the same time, the discharge tube resets simultaneously. Then, start the motor again to drive the raw material tray to rotate at the set angle. At this time, the cleaning cup is placed under the extraction tube, and the extraction process is repeated to pump the cleaning agent in the cleaning cup into the pipeline and then discharge it from the discharge tube into the waste cup, thus cleaning the pipeline of the previous residual raw materials. Then, start the electric hot air fan to dry the extraction pipeline through the air outlet pipe and the cross-connection pipe, and then you can proceed to sample the next type of additive.

[0036] The fuel additive detection and sampling device of this utility model can effectively solve the problems mentioned in the background technology. It achieves continuous multiple cleaning of pipelines during the sampling process based on the existing fuel additive detection and sampling device technology, and improves the efficiency of continuous sampling.
