Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of glue solution sampling, particularly relates to an automatic closed glue solution sampling tank. BACKGROUND

[0002] In the chemical industry, manual sampling of glue solution samples in a pipeline is a common operation. At present, the open type manual sampling method is adopted, and the specific process is as follows: a sampling bag is manually held and placed at the bottom of a sampling port to sample, and after sampling is completed, the sampling bag is sealed and sent to a laboratory for testing.

[0003] However, the current sampling process has many problems. On the one hand, before sampling, there is often residual waste glue in the pipeline that was not completely discharged during the last sampling. At this time, a certain amount of waste glue needs to be manually discharged before fresh glue solution can be cut off. However, the amount of waste glue discharged is large, and the solvent contained therein is a toxic substance. The environmental protection treatment of these waste glues is cumbersome, which not only increases the treatment cost, but also consumes a lot of manpower and material resources.

[0004] On the other hand, there are safety and health hazards in the sampling process. When the sampling amount is large, the operator will inevitably come into contact with the sample. The solvent in the glue solution volatilizes and can cause damage to the health of the operator, and also pollutes the surrounding environment. In addition, since the solvent is usually a flammable and explosive substance, if the operator has static electricity on his hands, it is easy to cause safety accidents during sampling, which poses a great safety risk.

[0005] In summary, the existing manual sampling method of glue solution samples in a chemical pipeline has obvious defects in environmental protection treatment, personnel health and safety, and an effective sampling device and method are needed to solve the above problems to achieve safe, environmentally friendly and efficient sampling of glue solution samples, avoid the trouble of waste glue treatment, reduce harm to personnel health and eliminate safety hazards. In view of this, an automatic closed glue solution sampling tank is proposed. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing an automatic closed glue solution sampling tank to solve the problems pointed out in the background art.

[0007] The above technical purpose of the utility model is realized by the following technical scheme:

[0008] An automatic closed glue solution sampling tank, comprising a sample inlet pipeline, a sample outlet pipeline, a water inlet pipeline, a water outlet pipeline, a tank body, a sampling bag, a sampling cup and a base, the tank body is provided with an opening at the bottom and is inserted at the top with the sample inlet pipeline, the sample outlet pipeline, the water inlet pipeline and the water outlet pipeline, the water inlet pipeline and the water outlet pipeline are connected, the sampling cup is arranged on the base, and the sampling bag is arranged in the sampling cup.

[0009] In a preferred embodiment, a sealing ring is further included on the base for sealing the gap between the base and the tank.

[0010] In a preferred embodiment, the sample inlet pipeline and the sample outlet pipeline are arranged in a long-short manner.

[0011] In a preferred embodiment, the lower ends of the sample inlet pipeline and the sample outlet pipeline are arranged in a bevel cut manner.

[0012] In a preferred embodiment, a pressure relief port is arranged on the tank.

[0013] In a preferred embodiment, a sealing member is arranged on the bag opening of the sampling bag.

[0014] In a preferred embodiment, the sealing member is arranged as a sealing zipper.

[0015] In a preferred embodiment, the sealing member includes a plurality of elastic ropes and a plurality of hard movable blocks, the plurality of elastic ropes are arranged inside the bag opening of the sampling bag by a first loop, the plurality of hard movable blocks are arranged inside the bag opening of the sampling bag by a second loop and below the plurality of elastic ropes, the hard movable blocks have an arc surface extending from the upper end to the lower end of the movable blocks.

[0016] In a preferred embodiment, the first loop and the second loop are arranged longitudinally and the upper and lower ends thereof are connected to the sampling bag respectively, the first loop surrounds the plurality of elastic ropes, the hard movable blocks are provided with threading holes, and the second loop passes through the threading holes.

[0017] In a preferred embodiment, the arc surface includes a first arc surface and a second arc surface, the first arc surface is above the second arc surface, and the curvature of the first arc surface is greater than that of the second arc surface.

[0018] Compared with the prior art, the automatic closed glue sampling tank is provided, before sampling, the sampling bag is manually sleeved into the sampling cup of the base, then the sampling tank is lifted by the automatic lifting mechanism, the sampling cup is inserted into the tank body to form a closed space, the sampling bag is completely wrapped in a closed environment to isolate external air. The water inlet pipeline and the water outlet pipeline are pre-connected, circulating water can be introduced according to the requirement, the temperature of the tank body is adjusted, and stable conditions are created for sampling.

[0019] In the waste glue processing link, the device discards the traditional manual waste glue discharge mode, when the sampling tank is connected with the main pipeline, the sample inlet pipeline and the sample outlet pipeline form a closed loop channel, the kinetic energy of the glue flow is utilized, the fresh glue gradually pushes the waste glue remaining in the sampling pipeline back to the main pipeline, and the waste glue is directly discharged.

[0020] When entering the automatic sampling stage, the glue solution continuously flows into the tank and is injected into the sampling bag. As the glue solution continuously flows in, the air in the tank is compressed, forming an increasing reverse air pressure. When the pressure of the inflowing glue solution and the air pressure in the tank reach a dynamic balance (i.e., the pressure value is stable and no longer rises), the glue solution liquid level no longer rises. This pressure balance driven automatic quantification mechanism does not require manual intervention.

[0021] After sampling is completed, the automatic lifting mechanism drives the tank to descend, and the sampling bag falls back with the sampling cup. At this time, the person only needs to take down the sampling bag to send it for inspection, without contacting the glue solution throughout the process, thereby eliminating the harm of solvent evaporation to the human body.

[0022] From the technical effect, the device reduces the manual operation link to only need to cover and take away the sampling bag through full automation design, significantly reduces the labor intensity of the operator, avoids the cumbersome and dangerous operation such as manually placing waste glue and manually holding the sampling bag to sample in the traditional sampling, and fundamentally solves the health risk of personnel contacting toxic solvents. The fully closed sampling process makes the glue solution always in a closed space, and the solvent evaporation is limited inside the sampling tank, thereby eliminating environmental air pollution. In view of the safety hidden danger of flammable and explosive solvents, the closed environment avoids the contact of static electricity and glue vapor, in combination with the insulation design of the automatic lifting mechanism, the possibility of safety accidents is greatly reduced. In the aspect of environmental protection, the waste glue reflux technology completely eliminates waste glue discharge, without subsequent treatment of a large amount of waste glue, thereby saving environmental protection cost; the pressure balance quantitative sampling technology ensures the accurate control of the sampling amount, avoids the unstable sample amount problem caused by operation difference in the traditional manual sampling, and improves the accuracy of laboratory inspection.

DETAILED DESCRIPTION

[0034] The utility model will be further explained in detail in combination with the drawings.

[0035] The specific embodiment is only the explanation of the utility model, and is not the limitation of the utility model, and the person skilled in the art can make the modification without the creative contribution according to the need after reading the present specification, but as long as in the utility model's right claim range all receive the patent law's protection.

[0036] As Figures 1 to 4 Indicated, an automatic closed glue solution sampling tank, including sample inlet pipeline 5, sample outlet pipeline 1, water inlet pipeline 3, water outlet pipeline 2, tank body 6, sampling bag 11, sampling cup 7 and base 9, the tank body 6 bottom opening is provided, and the top is inserted with sample inlet pipeline 5, sample outlet pipeline 1, water inlet pipeline 3 and water outlet pipeline 2, water inlet pipeline 3 and water outlet pipeline 2 are connected, sampling cup 7 is located on the base 9, and sampling bag 11 is located in sampling cup 7.

[0037] Water inlet pipeline 3 and water outlet pipeline 2 can be connected through cooling water tank 10.

[0038] The automatic closed glue solution sampling tank of the embodiment is manually sleeved with the sampling bag 11 into the sampling cup 7 of the base 9 before sampling, and then the sampling tank is lifted by the automatic lifting mechanism, the sampling cup 7 is inserted into the tank body 6, a closed space is formed, the sampling bag 11 is completely wrapped in the closed environment, and the outside air is isolated. The water inlet pipeline 3 is communicated with the water outlet pipeline 2, and cold condensate water can be introduced according to the demand, so that the temperature of the inside of the tank body 6 is adjusted, and stable conditions are created for sampling.

[0039] In the waste glue processing link, the device discards the traditional manual waste glue discharge mode. When the sampling tank is connected with the main pipeline, the sampling inlet pipeline 5 and the sampling outlet pipeline 1 form a closed loop channel. Fresh glue solution gradually pushes the waste glue remaining in the sampling pipeline back to the main pipeline by using the kinetic energy of glue solution flow, so that the waste glue is avoided from being directly discharged.

[0040] When the automatic sampling stage is entered, the glue solution continuously flows into the tank body 6 and is injected into the sampling bag 11. As the glue solution continuously enters, the air in the tank body 6 is compressed to form a gradually increasing reverse air pressure. When the pressure of the inflowing glue solution and the air pressure in the tank reach a dynamic balance (that is, the pressure value is stable and no longer rises), the glue solution liquid level no longer rises. This pressure balance driven automatic quantitative mechanism does not need manual intervention.

[0041] After sampling is completed, the automatic lifting mechanism drives the tank body 6 to descend, and the sampling bag 11 falls back with the sampling cup 7. At this time, the sampling bag 11 only needs to be taken off by manual operation, so that the sample can be sent for inspection, and the whole process does not need to contact the glue solution, so that the harm of solvent volatilization to the human body is avoided.

[0042] From the technical effect, the device reduces the manual operation link to only need to sleeve and take away the sampling bag 11 through full automation design, significantly reduces the labor intensity of the operator, avoids the cumbersome and dangerous operation such as manual waste glue discharge and hand-held sampling bag sampling in the traditional sampling, and fundamentally solves the health risk of personnel contacting toxic solvents. The whole closed sampling process makes the glue solution always in a closed space, limits the solvent volatilization in the inside of the sampling tank, and avoids environmental air pollution. In view of the safety hidden danger of flammable and explosive solvents, the closed environment avoids the contact between static electricity and glue vapor, and the insulation design of the automatic lifting mechanism greatly reduces the possibility of safety accidents. In the environmental protection aspect, the waste glue reflux technology completely eliminates the waste glue discharge, does not need to carry out subsequent treatment on a large amount of waste glue, saves the environmental protection cost, and the pressure balance quantitative sampling technology ensures the accurate control of the sampling amount, avoids the unstable problem of the sample amount caused by the operation difference in the traditional manual sampling, and improves the accuracy of laboratory inspection.

[0043] Reference Figure 4For the sampling process schematic, from left to right, from top to bottom, respectively: the first step: the sampling bag 11 is put on the sampling cup 7; the second step: the mechanism raises the sampling cup 7 into the tank body 6, seals, and then starts automatic sampling; the third step: the mechanism is controlled to descend; the fourth step: the sampling bag 11 is taken out.

[0044] In order to realize the sealing between the base 9 and the tank body 6, the automatic sealing glue sampling tank of the embodiment further comprises a sealing ring 8 arranged on the base 9 for sealing the gap between the base 9 and the tank body 6.

[0045] Further, the sampling inlet pipe 5 and the sampling outlet pipe 1 are arranged in long and short. Both of the two ports can be used to pump out the sample in the sampling bag for controlling different sample amounts, because the user sampling generally needs two specifications of sample amounts: large volume sample amount and small volume sample amount. When manually sampling, the sample amount is controlled by experience, while the present application can accurately control the sample amount by designing the lengths of the sampling inlet pipe and the sampling outlet pipe and using the pump back pumping method, and the same structure is used for quantification.

[0046] In order to avoid that the glue blocks the pipe port, the lower end of the sampling inlet pipe 5 and the sampling outlet pipe 1 is arranged with an inclined cut.

[0047] Further, the tank body 6 is provided with a pressure relief port 4, which can be used for pressure relief after sampling is completed, and the gas after pressure relief will first enter the filter for filtration and then be discharged into the air.

[0048] Further, the bag opening of the sampling bag 11 is provided with a sealing member.

[0049] The sealing member can be arranged as a sealing zipper.

[0050] In the embodiment, the preferred arrangement of the sealing member is as follows: refer to Figures 5 to 9The sealing member comprises a plurality of elastic ropes 12 and a plurality of hard movable blocks 14. The plurality of elastic ropes 12 are arranged on the inner side of the bag opening of the sampling bag 11 by a first ring. The plurality of hard movable blocks 14 are arranged on the inner side of the bag opening of the sampling bag 11 by a second ring 13 and below the plurality of elastic ropes 12. The hard movable blocks 14 have an arc surface extending from the upper end to the lower end of the movable blocks. In use, the sampling bag 11 is first placed in the sampling cup 7, and then the bag opening of the sampling bag 11 is turned over so that the bag opening of the sampling bag 11 reversely covers the cup opening of the sampling cup 7. At this time, the plurality of elastic ropes 12 and the plurality of hard movable blocks 14 are turned over to the outside of the cup opening, the upper and lower ends of the hard movable blocks 14 are reversed, and the elastic ropes 12 are turned over to below the hard movable blocks 14. During the turning over of the bag opening, the hard movable blocks 14 are controlled to protrude from the position of the cup opening. After the sampling bag 11 is placed, the sampling cup 7 is raised, the cup opening of the sampling cup 7 abuts against the inner top wall of the tank 6, the tank 6 abuts against the hard movable blocks 14 and is lowered, and the hard movable blocks 14 are lowered. During the lowering of the hard movable blocks 14, due to the arrangement of the arc surface, a part of the elastic ropes 12 is arched, and under the guidance of the arc surface, the elastic ropes 12 move from the lower end to the upper end of the hard movable blocks 14 after being turned over, so that the plurality of elastic ropes 12 are respectively arranged at the upper and lower ends of the hard movable blocks 14. When the sampling cup 7 is lowered, due to the effect of the elastic ropes 12 at the upper end of the hard movable blocks 14, the bag opening is retracted and withdrawn from the cup opening. The plurality of elastic ropes 12 realize automatic necking of the bag opening. Through such a structure, automatic necking of the bag opening can be realized after sampling is completed, and the environmental protection and the convenience of operation during sampling are further improved. After the necking is completed, the arrangement position of the sealing member forms a structure convenient for gripping, which is convenient for the operator to lift the sampling bag 11.

[0051] Further, the first ring and the second ring 13 are longitudinally arranged and connected to the sampling bag 11 at the upper and lower ends, respectively. The first ring surrounds the plurality of elastic ropes 12. The hard movable blocks 14 are provided with threading holes 15. The second ring 13 passes through the threading holes 15.

[0052] Specifically, the arc surface comprises a first arc surface 16 and a second arc surface 17. The first arc surface 16 is above the second arc surface 17. The curvature of the first arc surface 16 is greater than that of the second arc surface 17. Through the arrangement of the large curvature of the second arc surface 17, the elastic ropes 12 can pass the highest point under a short stroke of the hard movable blocks 14. Through the arrangement of the small curvature of the first arc surface 16, the elastic ropes 12 passing the highest point can be pushed to a farther place, so as to better play the function of automatic necking.

[0053] Further, the arched surface is provided with a guide piece 18, which is arranged obliquely downward, and the guide piece 18 comprises a plurality of guide strips 19. By arranging the guide strips 19, the elastic rope 12 is prevented from returning beyond the highest point of the hard movable block 14, and after the necking is completed, the plurality of guide pieces 18 formed by the plurality of guide strips 19 form a one-way channel structure, so that the volatile components of the glue solution are prevented from being volatilized, but the sampling from the sampling bag 11 is facilitated.

[0054] The automatic closed glue solution sampling tank of the embodiment can also be designed with a sweeping function on the base 9. Before the sampling tank is lowered after the sampling is completed, the small amount of solvent gas volatilized from the sample in the tank can be swept into the filter through the function.

[0055] The automatic closed glue solution sampling tank of the embodiment is installed in a sampling device, and the sampling device comprises a sampling tank automatic lifting mechanism, which comprises a lifting guide rail 20, a lifting screw rod 21 and a lifting motor 22.

[0056] The above description of the embodiments is for facilitating the understanding and use of the present application by ordinary skilled in the art, and those skilled in the art can easily make various modifications to the embodiments, and apply the general principles described herein to other embodiments without creative labor. Therefore, the present application is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art according to the disclosure of the present application without departing from the scope of the present application should be within the protection scope of the present application.
