Description

Technical Field

[0001] This utility model relates to the field of phenylethanol ketone detection and sampling, and in particular to an automated phenylethanol ketone quality detection and sampling device. Background Technology

[0002] Benzoin, also known as benzoin or benzoyl alcohol, is a colorless or white crystalline solid used as a pharmaceutical intermediate. It is also used in dye production, as a photosensitizer for photosensitive resins, in gravure inks, and in UV-curable coatings. Furthermore, it serves as a catalyst in polyester production. Benzoin is formed by the condensation of two molecules of benzaldehyde in a hot cyanide or vitamin B1 ethanol solution. Quality testing of benzoin typically requires sampling. Current sampling methods involve manually taking samples with pipettes and then weighing them. Benzoin can be irritating to the skin and eyes, requiring workers to wear gloves, goggles, and other protective equipment to avoid direct contact. This sampling method is cumbersome and time-consuming, reducing worker efficiency.

[0003] To address the above issues, an automated sampling and testing device for phenylethanol ketone needs to be designed to solve these technical problems. Utility Model Content

[0004] To overcome the drawbacks of cumbersome sampling methods, this invention provides an automated sampling device for the quality detection of diphenylethanol ketone.

[0005] The technical implementation scheme of this utility model is as follows: an automated sampling device for quality detection of diphenylethanol ketone, comprising a liquid extraction cylinder, a mounting frame, an electric push rod, a piston plate, a sampling tube, a one-way valve, a glass plate, a baffle, a first spring, a placement frame, and a weight sensor. The mounting frame is fixedly connected to the left side of the liquid extraction cylinder, and an electric push rod is fixedly connected to the top of the electric liquid extraction cylinder. The output shaft of the electric push rod is fixedly connected to the piston plate, which is slidably connected to the liquid extraction cylinder. A sampling tube is fixedly connected to the lower left side of the liquid extraction cylinder, and multiple liquid inlet holes are opened on the sampling tube. A one-way valve is installed on the right side of the sampling tube. Glass plates are provided on both the left and right sides of the liquid extraction cylinder. A baffle is slidably connected to the lower inner side of the liquid extraction cylinder, and a liquid outlet hole is opened at the bottom inner side of the liquid extraction cylinder. A first spring is fixedly connected between the baffle and the bottom of the liquid extraction cylinder. A placement frame is fixedly connected to the bottom of the liquid extraction cylinder, and a weight sensor is fixedly connected to the bottom of the placement frame.

[0006] Furthermore, the mounting bracket is also equipped with mounting holes.

[0007] Furthermore, it also includes a flow meter, which is installed at the bottom of the pumping cylinder.

[0008] Furthermore, it also includes a sliding sleeve and a float plate. The lower part of the sampling tube is fitted with a sliding sleeve, and the bottom of the sliding sleeve is connected to a float plate, which is slidably connected to the sampling tube.

[0009] Furthermore, it also includes sliding rods, clamping blocks, and second springs. Four sliding rods are slidably connected to both the left and right sides of the placement frame, and clamping blocks are fixedly connected between the four sliding rods on the same side. Second springs are fixedly connected between the clamping blocks and the placement frame, and the second springs are all sleeved on the sliding rods.

[0010] Furthermore, it also includes a controller, which is mounted on the mounting bracket and is electrically connected to the electric actuator, check valve, flow meter and weight sensor.

[0011] Beneficial effects: 1. This utility model, through the cooperation of sampling tube, liquid extraction cylinder, piston plate and electric push rod, eliminates the need for manual sampling by staff, making it more automated and improving the work efficiency of staff.

[0012] 2. This utility model uses the combination of an inlet hole, a sliding sleeve, and a float plate to float at the water level of diphenylethanol ketone. This prevents the inlet hole on the sampling tube that is not immersed in diphenylethanol ketone from being blocked by the sliding sleeve, thus preventing the subsequent sampling gas from being drawn in. Furthermore, the use of a one-way valve prevents the diphenylethanol ketone from flowing back.

[0013] 3. This utility model, through the combination of a flow meter and a weight sensor, allows staff to observe the sampling amount in real time and obtain the desired amount of diphenylethanol ketone.

[0014] 4. This utility model uses the cooperation of a sliding rod, a clamping block, and a second spring to fix the container, making sampling safer and more stable. Attached Figure Description

Detailed Implementation

[0022] Example: An automated sampling device for quality detection of phenylethanol ketone, such as... Figures 1-6 As shown, the device includes a suction cylinder 1, a mounting bracket 2, an electric push rod 3, a piston plate 4, a sampling tube 5, a one-way valve 6, a glass plate 7, a baffle 8, a first spring 9, a placement rack 11, and a weight sensor 12. The mounting bracket 2 is welded to the left side of the suction cylinder 1, and the mounting bracket 2 is also provided with a mounting hole 202. An electric push rod 3 is installed on the top of the electric suction cylinder 1, and the output shaft of the electric push rod 3 is fixedly connected to the piston plate 4. The piston plate 4 is slidably connected to the suction cylinder 1. A sampling tube 5 is fixedly connected to the lower left side of the suction cylinder 1, and multiple liquid inlet holes 501 are opened on the sampling tube 5. A one-way valve 6 is installed on the right side of the sampling tube 5. Glass plates 7 are provided on both the left and right sides of the suction cylinder 1. A baffle 8 is slidably connected to the lower inner side of the suction cylinder 1. A liquid outlet hole 801 is opened at the bottom inner side of the suction cylinder 1. A first spring 9 is fixedly connected between the baffle 8 and the bottom of the suction cylinder 1. A placement rack 11 is welded to the bottom of the suction cylinder 1, and a weight sensor 12 is installed at the bottom of the placement rack 11.

[0023] like Figure 2 As shown, it also includes a flow meter 10, which is installed at the bottom of the pumping cylinder 1.

[0024] like Figure 1 and Figure 5 As shown, it also includes a sliding sleeve 13 and a float plate 14. The lower part of the sampling tube 5 is fitted with a sliding sleeve 13, and the bottom of the sliding sleeve 13 is connected to a float plate 14. The float plate 14 is slidably connected to the sampling tube 5.

[0025] like Figure 6 As shown, it also includes a slide rod 15, a clamping block 16, and a second spring 17. Four slide rods 15 are slidably connected to both the left and right sides of the placement frame 11. Clamping blocks 16 are fixedly connected between the four slide rods 15 on the same side. The clamping blocks 16 and the placement frame 11 are fixedly connected to the second spring 17. The second spring 17 is sleeved on the slide rod 15.

[0026] like Figure 1 and Figure 2 As shown, it also includes a controller 201, which is mounted on the mounting bracket 2. The controller 201 is electrically connected to the electric push rod 3, the one-way valve 6, the flow meter 10, and the weight sensor 12.

[0027] When this device is needed for automated sampling and quality testing of phenylethanol ketone, first install the device on the upper side of the container containing phenylethanol ketone through the mounting hole 202 on the mounting bracket 2, and position the sampling tube 5 inside the container containing phenylethanol ketone. The sliding sleeve 13 and float plate 14 on the sampling tube 5 slide upward according to the water level of phenylethanol ketone in the container, floating at the water level of phenylethanol ketone, so that the liquid inlet hole 501 on the sampling tube 5 that is not immersed in phenylethanol ketone is blocked by the sliding sleeve 13 to prevent the subsequent sampling gas from being drawn in. Then, squeeze the container into the clamping block 16, and at the same time, the second spring 17 is compressed, and the slide rod 15 and the clamping block 16 move away from the center end. After the container is placed on the weight sensor 12, the second spring 17 extends and drives the clamping block 16 and the slide rod 15 to clamp the container.

[0028] The controller 201 activates the electric push rod 3, the one-way valve 6, the flow meter 10, and the weight sensor 12. When the electric push rod 3 moves the piston plate 4 upward, the suction force generated inside the suction cylinder 1 draws diphenylethanol ketone into the suction cylinder 1 through the inlet hole 501 on the sampling tube 5. When the electric push rod 3 moves the piston plate 4 downward, the diphenylethanol ketone does not flow back due to the action of the one-way valve 6, the baffle 8 is squeezed, the first spring 9 is compressed, and the diphenylethanol ketone flows into the container from the outlet hole 801. At the same time, the flow meter 10 measures the inflowing diphenylethanol ketone, and the weight sensor 12 weighs the diphenylethanol ketone. When the electric push rod 3 moves the piston plate 4 upward again, the first spring 9 extends and drives the baffle 8... The liquid outlet 801 is then blocked again, and the glass plate 7 on the suction cylinder 1 is placed for easy observation by the staff. Then, the electric push rod 3 drives the piston plate 4 to move up and down repeatedly to continuously collect diphenylethanol ketone. The staff checks the data displayed on the flow meter 10 and the weight sensor 12. After the desired amount of diphenylethanol ketone has been sampled, the electric push rod 3, the one-way valve 6, the flow meter 10 and the weight sensor 12 are closed by the controller 201. Then, the clamp 16 is pried open, the second spring 17 is compressed, and the container containing diphenylethanol ketone is taken out. The second spring 17 extends and drives the clamp 16 and the slide rod 15 to reset. The staff can then process the sampled diphenylethanol ketone.
