Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of glue solution sampling, particularly to a closed glue solution sampling tank with cooling function. BACKGROUND

[0002] In the chemical industry, manual sampling of glue solution samples in the pipeline is the current common way. The specific operation is to manually hold a sampling bag at the bottom of the sample port to take samples, and then seal and send it to the laboratory for testing after sampling is completed. However, this sampling process has many problems to be solved.

[0003] Before sampling, a large amount of waste glue remaining in the pipeline needs to be manually discharged. The toxic solvents contained in the waste glue not only complicate the treatment process, but also cause resource waste. During the sampling process, when the number of samples is large, the operator directly contacts the glue solution, and the solvent volatilization in the glue solution can harm human health and pollute the environment. At the same time, the flammable and explosive solvent may interact with the static electricity of the operator, causing safety hazards. In addition, the temperature of the glue solution is 50-90℃, the high temperature causes the solvent to volatilize, aggravates environmental pollution and health threat, and also has the risk of scalding the operator.

[0004] Even if an automatic closed sampling mechanism is used, new challenges are faced. After sampling is completed, because the temperature of the glue solution is high, the temperature of the sampling tank periphery rises, and the sampling bag needs to be taken down after cooling, prolonging the sampling process. Moreover, if the glue solution cannot be quickly cooled, the solvent will volatilize in large quantities when the sampling tank is opened, which is contrary to the original intention of reducing pollution. For the sampling tank with a condenser inserted into the glue solution, there is a problem of low cooling efficiency, the glue solution will be adsorbed on the condenser tube, pollute the subsequent samples, and the residual glue solution will also cause environmental pollution and affect subsequent use when separated.

[0005] In summary, the existing glue solution sampling method of the chemical pipeline has many problems in safety, environmental protection, efficiency, etc., and innovative technology and improvement scheme are needed to optimize the sampling process and solve the above-mentioned drawbacks. Therefore, a closed glue solution sampling tank with cooling function is proposed. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0033] The utility model will be further described in detail below in connection with drawings.

[0034] The present embodiment is merely an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the present embodiment without creative contribution after reading the present specification, as long as the modifications are within the scope of the claims of the utility model and are protected by the patent law.

[0035] As Figures 1 to 13 shown, a kind of closed glue liquid sampling tank with cooling function, including sample inlet line 1, sample outlet line 3, tank 4, sampling cup 5, sampling bag 29 and heat sink water tank 7, the sample inlet line 1 and the sample outlet line 3 are inserted into the tank 4 via the top of the tank 4, the tank 4 bottom is open and is arranged, the sampling cup 5 is located in the heat sink water tank 7.

[0036] The closed glue solution sampling tank with a cooling system of the embodiment is butted to the main pipeline through the sampling pipeline, and the residual waste glue in the main pipeline is flushed back to the main pipeline by the fresh glue solution by using the flow of the glue solution in the sampling pipeline. After a certain period of flow, it is ensured that the entire pipeline is filled with fresh glue solution. Before sampling, the operator first puts the sampling bag 29 into the sampling cup 5, and then puts the sampling cup 5 into the heat dissipation water tank 7. At this time, the heat dissipation water tank 7 starts the automatic lifting program and is precisely butted to the bottom of the tank body 4 to form a complete closed space. During the sampling process, the glue solution enters the sampling tank through the sampling pipeline 1 and flows out of the sampling pipeline 3 along the set path under the push of compressed air. Due to the closed nature of the system, the glue solution is completely confined in the tank body 4, avoiding contact with the outside world during the sampling process, effectively preventing the toxic solvent in the glue solution from volatilizing into the atmosphere, and also eliminating the possibility of direct contact of the operator with the glue solution. In this process, as the glue solution continuously flows in, the air in the sampling tank is compressed, and when the pressure of the inflowing glue solution and the pressure in the tank reach equilibrium, the glue solution stops flowing in, realizing automatic quantitative sampling. Not only is the sampling efficiency improved, but also waste and pollution caused by glue solution overflow are avoided. At the same time, the condensate pipeline of the heat dissipation water tank 7 starts to circulate and inject condensate water. The condensate water flows in the water tank and quickly removes the heat emitted by the glue solution through the heat exchange principle, accelerating the cooling of the glue solution. Compared with the traditional sampling method, this cooling design can significantly shorten the glue solution cooling time and avoid the problem of prolonged sampling process caused by high temperature of the glue solution. After sampling is completed, the heat dissipation water tank 7 automatically descends and separates from the tank body 4. At this time, the user can safely take out the sampling bag 29 containing the glue solution sample, and the entire sampling process is convenient and efficient.

[0037] In terms of safety, the closed sampling structure isolates the glue solution from the operator, and also avoids the safety hazards caused by contact between flammable and explosive solvents in the glue solution and static electricity. The rapid cooling design reduces the risk of glue burns. In terms of environmental protection, the volatilization of toxic solvents in the glue solution is effectively inhibited, reducing pollution to the environment. Unlike the traditional condensing tank, which can easily contaminate the sample, the cooling method of the sampling tank will not cause the glue solution to be adsorbed on the cooling components, ensuring the purity of the sample. In terms of efficiency, the automatic docking and cooling functions greatly reduce the sampling time, and the automatic lifting operation of the heat dissipation water tank 7 simplifies the process and improves the overall work efficiency. Compared with traditional manual sampling or other automatic sampling methods, it can better meet the efficient and accurate sampling needs of the chemical industry.

[0038] The inner wall of the heat dissipation water tank 7 is provided with a sandwich layer, and the side part is provided with a cooling water inlet 9 and a cooling water outlet 10, which are connected to the sandwich layer. The sandwich layer has many advantages: first, the heat exchange area is greatly expanded through the surrounding sandwich structure, so that the cooling water and the outer wall of the sampling cup 5 form a full-wrapped contact, and the forced circulation of the cooling water flow significantly improves the heat conduction efficiency and avoids the process delay caused by long-time waiting for cooling; second, the sandwich indirect cooling eliminates the direct contact between the cooling water and the glue solution, completely solves the sample pollution problem caused by the adsorption of the glue solution in the traditional condenser pipe, ensures the purity of each sampling, and avoids the pollution of the environment caused by the dropping of the residual glue solution; third, the sandwich layer is an independent cooling medium channel, which can be selected with different cooling working substances (such as water and glycol solution) to adapt to different glue solution temperature requirements, and is easy to maintain and clean, avoids the blockage of the cooling system, and isolates the influence of high temperature of the glue solution on the water tank body, prolonging the service life of the equipment.

[0039] The sandwich layer is provided with a flow guide plate 14, which divides the sandwich layer space into a spiral channel. The spiral channel makes the cooling water flow along a spiral path, significantly prolongs the heat exchange stroke, enhances the turbulent effect, destroys the boundary layer, and the spiral flow channel is attached to the outer wall of the sampling cup 5, eliminating the flow dead angle.

[0040] The heat dissipation water tank 7 is provided with a central protrusion, and the sandwich layer is provided with a flow guide pipe 15 corresponding to the central protrusion, and the flow guide pipe 15 is connected to the cooling water outlet 10. The design of the central protrusion expands the surface area of the inner wall of the sandwich layer through a three-dimensional structure, so that the contact range of the cooling water is larger than that of the plane structure, forming more heat exchange interfaces.

[0041] Specifically, the heat dissipation water tank 7 includes an aluminum alloy heat conduction cavity 11 and a water circulation cavity 13, the aluminum alloy heat conduction cavity 11 is arranged in the water circulation cavity 13, and the aluminum alloy heat conduction cavity 11 and the water circulation cavity 13 form the sandwich layer. Through such a setting, the heat dissipation is vertically divided, so that the heat dissipation water tank 7 is easy to process.

[0042] In order to realize the sealing arrangement, the top of the water circulation cavity 13 is provided with a sealing ring 126 for closing the gap between the water circulation cavity 13 and the aluminum alloy heat conduction cavity 11.

[0043] In order to realize the side support of the heat dissipation water tank 7, the side part of the heat dissipation water tank 7 is provided with a water tank support 8.

[0044] The top of the tank body 4 is provided with a pressure relief port 2. When the sampling is completed, the pressure relief can be carried out through the pressure relief channel, and the gas after pressure relief will first enter the filter for filtration and then be discharged into the air.

[0045] The bottom of the sample inlet pipeline 1 and the sample outlet pipeline 3 is provided in the form of a bevel to avoid blocking of the pipeline opening by glue solution. Meanwhile, the sample amount can be quantified by back-pumping of the sampling pump.

[0046] In order to realize large sample taking and small sample taking, different sampling cups 5 can be provided for large sample taking and small sample taking respectively. When taking a small sample, a strict cooling process is not required.

[0047] A necking member can be provided on the bag opening of the sampling bag 29. The necking member can be provided in various forms, for example, in the form of a sealed zipper. In the embodiment, the necking member comprises a plurality of elastic ropes 30 and a plurality of hard movable blocks 32. The plurality of elastic ropes 30 are arranged inside the bag opening of the sampling bag 29 by a first loop, and the plurality of hard movable blocks 32 are arranged inside the bag opening of the sampling bag 29 by a second loop 31 and below the plurality of elastic ropes 30. The hard movable blocks 32 have an arched surface extending from the upper end to the lower end of the movable blocks. In use, the sampling bag 29 is first placed in the sampling cup 5, and then the bag opening of the sampling bag 29 is turned over to be reversely sleeved on the cup opening of the sampling cup 5. At this time, the plurality of elastic ropes 30 and the plurality of hard movable blocks 32 are turned outside the cup opening, the hard movable blocks 32 are upside down, and the elastic ropes 30 are turned below the hard movable blocks 32. During turning over of the bag opening, the hard movable blocks 32 are controlled to protrude from the position of the cup opening. After the sampling bag 29 is placed, the sampling cup 5 is raised, the cup opening of the sampling cup 5 abuts against the inner top wall of the tank 4, the tank 4 abuts against the position of the hard movable blocks 32, and the position of the hard movable blocks 32 is lowered. During lowering of the position of the hard movable blocks 32, due to the arrangement of the arched surface, a part of the elastic ropes 30 is arched, and under the guidance of the arched surface, the elastic ropes 30 are moved from the lower end to the upper end of the turned hard movable blocks 32, so that the plurality of elastic ropes 30 are respectively arranged at the upper and lower ends of the hard movable blocks 32. When the sampling cup 5 is lowered, due to the action of the elastic ropes 30 at the upper end of the hard movable blocks 32, the bag opening is retracted and withdrawn from the cup opening. The plurality of elastic ropes 30 realize automatic necking of the bag opening. Thus, by the structural arrangement, automatic necking of the bag opening can be realized after sampling, and the environmental protection and the convenience of operation during sampling are further improved. After necking is completed, the arrangement position of the necking member forms a structure convenient for gripping, so that the sampling bag 29 can be easily lifted by the operator.

[0048] Further, the first loop and the second loop 31 are longitudinally arranged and connected to the sampling bag 29 at the upper and lower ends respectively. The first loop surrounds the plurality of elastic ropes 30, the hard movable blocks 32 are provided with threading holes 33, and the second loop 31 passes through the threading holes 33.

[0049] Specifically, the arc surface comprises a first arc surface 34 and a second arc surface 35, the first arc surface 34 is located above the second arc surface 35, and the curvature of the first arc surface 34 is greater than that of the second arc surface 35. By setting the large curvature of the second arc surface 35, the elastic cord 30 can pass the highest point under a shorter stroke of the hard movable block 32, and by setting the small curvature of the first arc surface 34, the elastic cord 30 passing the highest point can be pushed to a farther place, better exerting the function of automatic necking.

[0050] Further, the arc surface is provided with a guide piece 36, the guide piece 36 is inclined downward, and the guide piece 36 comprises a plurality of guide strips 37. By setting the guide strips 37, the elastic cord 30 passing the highest point of the hard movable block 32 is prevented from retreating, and after the necking is completed, the plurality of guide pieces 36 formed by the plurality of guide strips 37 form a one-way channel structure, avoiding the volatilization of the glue components, but facilitating sampling from the sampling bag 29.

[0051] The closed glue liquid sampling tank with a cooling system of the embodiment is installed on a sampling device, the sampling device is provided with a sampling tank automatic lifting mechanism, the sampling tank automatic lifting mechanism comprises a lifting platform upper limit switch 23, a lifting guide slide rail 24, a heat dissipation water tank 7, a lifting platform lower limit switch 26, a door control switch 27 and a lifting motor 28, and is used for realizing related sampling operations.

[0052] The above description of the embodiments is for the purpose of facilitating the ordinary skilled person in the art to understand and use the present application, and the person 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 the person skilled in the art without departing from the scope of the present application should be within the protection scope of the present application.
