Description

Technical Field

[0001] This utility model relates to the field of catalyst production technology, specifically to a catalyst production device for polyurethane runways. Background Technology

[0002] When producing catalysts for polyurethane running tracks, various liquid raw materials need to be added. In existing technologies, raw materials are generally transported through a liquid outlet pipe and then discharged in a quantitative manner. In actual operation, it is necessary to regularly sample and inspect the raw materials to ensure the production quality of the catalyst. In existing production equipment, when sampling raw materials, a measuring cup is usually placed directly at the liquid outlet pipe to collect the raw materials for testing. This sampling method allows the additives to be directly washed away by the sampling cup, which can easily lead to additive contamination and affect the production quality of the catalyst. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a catalyst production device for polyurethane running tracks. By cooperating with the additive addition component and the sampling component, non-contact interception sampling is achieved during use, avoiding the problem of additive contamination caused by the outer wall of the measuring cup being washed away during the sampling process, thus ensuring the production quality of the catalyst. Furthermore, there is no need to reduce the liquid discharge rate and slowly sample from the end of the liquid discharge pipe, which also ensures the liquid discharge efficiency.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a catalyst production apparatus for polyurethane running tracks, comprising:

[0005] An additive adding component includes a circular frame, a liquid outlet pipe passing through the circular frame, a limiting cylinder fixed at the position of the liquid outlet pipe, a liquid storage bottle disposed above the circular frame, a liquid outlet head communicating with the liquid storage bottle, and a shut-off valve disposed on the liquid outlet pipe.

[0006] The sampling assembly includes a second hole at the location of the liquid outlet tube, a long tube communicating with the second hole, a first hole at the long tube, a sampling tube communicating with the first hole, a rubber stopper sealing the sampling tube, a round rod inserted into the long tube, a plug fixed to the top of the round rod, and a rubber ring disposed on the outer wall of the plug.

[0007] In a preferred embodiment of the polyurethane runway catalyst production device described in this utility model, three rubber rings are provided, and the three rubber rings are distributed at equal intervals.

[0008] The rubber ring is in contact with the inner wall of the long tube.

[0009] In a preferred embodiment of the polyurethane runway catalyst production device described in this utility model, the liquid outlet head is inserted into the liquid outlet pipe, and the limiting cylinder limits the liquid storage bottle.

[0010] As a preferred embodiment of the polyurethane runway catalyst production device described in this utility model, the liquid outlet pipe is provided in a plurality of manners, and the plurality of liquid outlet pipes are arranged in a ring.

[0011] Each outlet tube is equipped with a corresponding sampling component.

[0012] As a preferred embodiment of the polyurethane runway catalyst production device of the present invention, it further includes an indicator component, which includes an annular groove formed on the bottom surface of the limiting cylinder and a spring disposed in the annular groove.

[0013] The springs are distributed in annular rings within the annular groove.

[0014] In a preferred embodiment of the polyurethane runway catalyst production device described in this utility model, the indicating component further includes an annular plate fixed to the top of the spring.

[0015] The bottom surface of the liquid storage bottle is in contact with the top surface of the annular plate.

[0016] In a preferred embodiment of the polyurethane runway catalyst production device described in this utility model, each limiting cylinder is provided with a corresponding indicating component, and each indicating component has the same structure.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] First, by combining the additive addition component and the sampling component, non-contact interception sampling is achieved during use.

Furthermore, it eliminates the need to reduce the liquid discharge rate and slowly sample from the end of the liquid discharge tube, ensuring liquid discharge efficiency.

[0019] Second, by setting up an indicator component, the height of the liquid storage bottle changes as the weight of the liquid gradually decreases, which conveniently alerts staff whether the liquid storage bottle is low on liquid and facilitates observation. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] This utility model provides a catalyst production device for polyurethane running tracks. Through the cooperation of the additive addition component and the sampling component, non-contact interception sampling is achieved during use. This avoids the problem of the additive being washed away by the outer wall of the measuring cup during the sampling process, thus preventing the additive from being contaminated. This ensures the production quality of the catalyst. Furthermore, it eliminates the need to reduce the liquid discharge rate and slowly sample from the end of the liquid discharge pipe, ensuring liquid discharge efficiency.

[0031] Figures 1-4 The diagram shown is an overall structural schematic of an embodiment of a polyurethane runway catalyst production device according to this utility model. Please refer to [link / reference]. Figures 1-4 The main structure of this embodiment includes: an additive addition component and a sampling component.

[0032] The additive adding component is used for adding additives. Specifically, the additive adding component includes a circular frame 11, a liquid outlet pipe 12 passing through the circular frame 11, a limiting cylinder 13 fixed at the position of the liquid outlet pipe 12, a liquid storage bottle 14 set above the circular frame 11, a liquid outlet head 15 communicating with the liquid storage bottle 14, and a shut-off valve 16 set on the liquid outlet pipe 12.

[0033] In actual use, the user directly inserts the dispensing head 15 into the top of the dispensing tube 12, and then the additive flows through the dispensing head 15 into the inner cavity of the dispensing tube 12 and is finally discharged. The shut-off valve 16 is used to control the opening and closing of the dispensing tube 12.

[0034] The sampling component is used in conjunction with the additive addition component to complete non-contact sampling. Specifically, the sampling component includes a second hole 26 opened at the position of the liquid outlet tube 12, a long tube 21 communicating with the second hole 26, a first hole 25 opened on the long tube 21, a sampling tube 22 communicating with the first hole 25, a rubber stopper 23 sealing the sampling tube 22, a round rod 24 inserted into the long tube 21, a plug 27 fixed at the top of the round rod 24, and a rubber ring 28 set on the outer wall of the plug 27.

[0035] In practical use, the user pulls down the round rod 24, which moves the plug 27 and rubber ring 28 down simultaneously until the plug 27 moves below the first hole 25. At this point, the second hole 26 is no longer blocked, and the additive in the outlet tube 12 flows through the second hole 26 to the long tube 21, and finally to the sampling tube 22. Then, the user pushes the round rod 24 up until the plug 27 seals the second hole 26. At this point, the user aligns the measuring cup with the sampling tube 22 and then removes the rubber stopper 23. The additive can then flow into the measuring cup, thus avoiding the problem of the additive being washed away by the outer wall of the measuring cup during the sampling process, which would cause the additive to be contaminated.

[0036] Furthermore, it also includes an indicator component, which includes an annular groove 31 opened on the bottom surface of the inner side of the limiting cylinder 13 and a spring 32 disposed in the annular groove 31.

[0037] Among them, the spring 32 is distributed in a ring shape within the annular groove 31;

[0038] The indicating assembly also includes an annular plate 33 fixed to the top of the spring 32;

[0039] The bottom surface of the liquid storage bottle 14 is in contact with the top surface of the annular plate 33;

[0040] In practical use, the storage bottle 14 is filled with additives. The weight of the storage bottle 14 plus the additives will directly press the annular plate 33 into the annular groove 31. At this time, the spring 32 is compressed. As the storage bottle 14 gradually discharges liquid, the weight of the storage bottle 14 gradually becomes lighter. At this time, the weight of the storage bottle 14 plus the additives gradually becomes less than the elastic force of the compressed spring 32. Thus, the spring 32 gradually recovers its deformation, directly driving the annular plate 33 to push the storage bottle 14 upward. The position of the storage bottle 14 changes, and the liquid outlet 15 also moves in the liquid outlet tube 12. In this way, the position of the storage bottle 14 can be used to determine whether there is a shortage of liquid. Until the additives are completely discharged, the liquid outlet 15 separates from the liquid outlet tube 12.

[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
