Technical Field
[0001] The utility model relates to the technical field of chemical waste liquid collecting devices, and specifically designs a polyester polyol waste liquid collecting device. Background Art
[0002] The market requires polyurethane to be competent in more and more aspects. Therefore, in order for a specific polyurethane to have specified physical and chemical properties, its raw materials (polyester polyols) are required to have such physical and chemical properties in order to achieve the purpose of transfer. This situation directly leads to the multiplicity and complexity of polyester polyol brands, which further leads to the difficulty in handling polyester polyol tailings. In addition, polyester polyols have the characteristics of viscosity, easy crystallization, and easy moisture absorption. Therefore, the safe, effective and rapid transfer and dumping of tailings has become a problem. Among the existing measures for collecting polyester polyol tailings, the conventional collection measure is to move the tailings into a galvanized small-mouthed barrel to ensure that the tailings will not be exposed to the air and absorb too much moisture in the air, thereby controlling the water absorption of the tailings.
[0003] However, due to the small diameter of the galvanized barrel and the high viscosity of the polyester polyol tailings, the collected tailings are easily spilled when directly dumped. Therefore, the staff usually installs a plastic funnel at the barrel mouth before dumping it. The workers often find a funnel temporarily when they are about to dump the tailings, resulting in the funnel being so large that even the funnel mouth cannot be inserted into the barrel mouth of the galvanized barrel, or the funnel is so small that it is difficult to operate at all. Even if it is more suitable, its stability is poor due to the mismatch between the funnel mouth and the barrel mouth, and another worker is required to straighten the funnel. Otherwise, when dumping the tailings, the funnel position is easily shifted by the impact of the tailings, and there is still a risk of spilling. Based on this, the inventor purposefully provides a collection device for polyester polyol waste liquid that can stably drain the waste liquid into a barrel. Utility Model Content
[0004] The utility model aims to provide a collection device for polyester polyol waste liquid in view of the deficiencies of the prior art, so as to solve the problems in the prior art.

[0019] 1. When the collecting funnel of the utility model is fully inserted into the galvanized barrel, the three support frames are in a fully unfolded state to form a stable tripod base, thereby providing a stable supporting force for the collecting funnel. In this way, when pouring the polyester polyol waste liquid, there is no need for workers to straighten the collecting funnel, and the tripod base can absorb and disperse the impact force of pouring the polyester polyol waste liquid on the collecting funnel, ensuring that the position of the collecting funnel will not shift during the pouring process, and the waste liquid can be drained into the galvanized barrel, avoiding the situation of spilling the material.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] See also Figure 1-Figure 5, a collection device for polyester polyol waste liquid, comprising a galvanized barrel 1, a barrel mouth 2 is provided on the top of the galvanized barrel 1, a collecting funnel 3 is inserted in the barrel mouth 2, a buffer portion 11 is provided at the abutment between the collecting funnel 3 and the barrel mouth 2, and the diameter of the buffer portion 11 increases upward along the axial direction of the collecting funnel 3, an inverted cone sealing ring is sleeved on the buffer portion 11, three semicircular grooves 13 are provided on the circumference of the outer circumference of the collecting funnel 3, a ring 5 is sleeved on the collecting funnel 3, three support frames 4 are rotatably installed on the ring 5, and the three support frames 4 are arranged in a circle, one end of each collecting funnel 3 is abutted against the top of the galvanized barrel 1, and the other end of each collecting funnel 3 is provided with a groove 7, each groove 7 is slidably connected with a missing corner round wheel 6, and the missing corner round wheel 6 is connected to the inner wall of the groove 7 through a spring 8;
[0032] When the collecting funnel 3 is gradually inserted into the barrel mouth 2, one ends of the three support frames 4 will abut against the top of the galvanized barrel 1, and they will slide as the collecting funnel 3 is inserted into the top of the galvanized barrel 1. At this time, the support frame 4 rotates on the ring 5, and the notched round wheel 6 at the other end of the support frame 4 will abut against the surface of the collecting funnel 3, and the spring 8 is squeezed and deformed. When the collecting funnel 3 is fully inserted into the barrel mouth 2, the inverted cone sealing ring between the buffer part 11 and the barrel mouth 2 is squeezed and deformed, and the three support frames 4 are fully unfolded, one end of which stops moving at the top of the galvanized barrel 1, and the notched round wheel 6 at the other end abuts against the semicircular groove 13, and the spring 8 is fully extended.
[0033] The working principle of the utility model is as follows: the cover on the barrel mouth 2 is removed, and then the collecting funnel 3 is inserted into the galvanized barrel 1 through the barrel mouth 2. At this time, one end of the three support frames 4 is all against the top of the galvanized barrel 1, and as the collecting funnel 3 is inserted, one end of the support frame 4 will slide on the top of the galvanized barrel 1, thereby driving the support frame 4 to rotate on the ring 5, and then the notched round wheel 6 at the other end rotates and abuts against the surface of the collecting funnel 3. As the collecting funnel 3 continues to go deeper, the rotation and expansion amplitude of the support frame 4 becomes larger, and the notched round wheel 6 at the other end rotates and abuts against the surface of the collecting funnel 3. The position where the round wheel 6 abuts the collecting funnel 3 will gradually move downward, and the notched round wheel 6 will be squeezed and moved into the groove 7. At this time, the spring 8 will shrink until the notched round wheel 6 moves to the semicircular groove 13. Under the elastic force of the spring 8, the notched round wheel 6 will be pushed into the semicircular groove 13, thereby achieving snap-fit. At this time, the collecting funnel 3 is completely inserted into the galvanized barrel 1, and the inverted cone sealing ring at the abutment between the buffer portion 11 and the barrel mouth 2 is squeezed and deformed, thereby preventing external air from entering the galvanized barrel 1 through the gap.
[0034] When the collecting funnel 3 is fully inserted into the galvanized barrel 1, the three support frames 4 are in a fully unfolded state, forming a stable tripod base, thereby providing a stable supporting force for the collecting funnel 3. In this way, when pouring the polyester polyol waste liquid, there is no need for workers to straighten the collecting funnel 3, and the tripod base can absorb and disperse the impact force of the pouring of the polyester polyol waste liquid on the collecting funnel 3, ensuring that the position of the collecting funnel 3 will not shift during the pouring process, and the waste liquid can be drained into the galvanized barrel 1, avoiding the situation of spilling the material.
[0035] Furthermore, the outer diameter of the buffer portion 11 increases from bottom to top, which expands the diameter range of the barrel mouth 2 that the buffer portion 11 can adapt to, thereby improving the compatibility of the collecting funnel 3 and the galvanized barrel 1 .
[0036] Moreover, due to the clamping connection between the notched circular wheel 6 and the semicircular groove 13, when the collecting funnel 3 is subjected to the rebound force of the inverted conical sealing ring, the rebound force will be decomposed along the arc-shaped contact surface between the notched circular wheel 6 and the semicircular groove 13, generating a force against the inverted conical sealing ring, thereby ensuring that the inverted conical sealing ring will be deformed, thereby achieving a sealing effect, and further ensuring that when dumping waste liquid, outside air enters the galvanized barrel 1 through the gap between the collecting funnel 3 and the barrel mouth 2, causing the polyester polyol waste liquid to be contaminated, and also preventing the gas volatilized from the polyester polyol waste liquid in the galvanized barrel 1 from overflowing into the environment outside the barrel, thereby protecting the personal safety of the staff and the environment.
[0037] Specifically, the three grooves 7 are each provided with a limiting groove 10 , and limiting blocks 9 are fixedly installed on both sides of the three corner-cut circular wheels 6 , and the limiting blocks 9 are slidably connected to the limiting grooves 10 .
[0038] In a specific embodiment, when the notched circular wheel 6 abuts against the outer wall of the collecting funnel 3, as the rotation amplitude of the support frame 4 increases, the notched circular wheel 6 will slide into the groove 7 under the abutment of the collecting funnel 3, and the limiting blocks 9 on both sides of the notched circular wheel 6 will slide in the limiting groove 10, thereby ensuring that the sliding direction of the notched circular wheel 6 in the groove 7 is consistent with the opening direction of the groove 7.
[0039] More specifically, the discharge port of the collecting funnel 3 is provided with a pointed mouth 12 .
[0040] In a specific embodiment, due to the high viscosity of the polyester polyol waste liquid, if the discharge end of the collecting funnel 3 is a flat mouth, then when the polyester polyol waste liquid passes through the flat mouth, its surface tension will be very large, resulting in poor flow of the waste liquid, especially after the waste liquid is poured, a small amount of waste liquid is in the collecting funnel 3, and the surface tension will cause the waste liquid to form a liquid bridge at the outlet, generating greater resistance, making it difficult for the liquid to flow out, resulting in part of the waste liquid remaining in the collecting funnel 3, and the shape of the pointed mouth 12 can generate a higher shear force when the waste liquid passes through, and this shear force helps to break the intermolecular interaction inside the waste liquid, reduce the influence of surface tension, prevent the formation of liquid bridges, and avoid the waste liquid from remaining in the collecting funnel 3.
[0041] At the same time, it should be noted that the feeding port of the collecting funnel 3 is fixedly installed with two extension parts 14, and the two extension parts 14 are symmetrically arranged. The feeding port of the collecting funnel 3 is provided with a removable top cover 16, and two arc-shaped blocks 18 that are engaged with the extension parts 14 are symmetrically arranged on the top cover 16, and an annular sealing ring is provided at the joint between the top cover 16 and the collecting funnel 3.
[0042] In a specific embodiment, by adding a detachable top cover 16, after the dumping work is completed, the top cover 16 is promptly installed on the top of the collecting funnel 3 to completely isolate the galvanized barrel 1 from the outside air, thereby minimizing the risk of volatile waste escaping to the outside.
[0043] More specifically, a first handle 15 is fixedly mounted on the outer circumferential surface of the collecting funnel 3 .
[0044] In a specific embodiment, the first handle 15 is installed to facilitate the movement and installation of the collecting funnel 3 .
[0045] Meanwhile, it should be noted that a second handle 17 is fixedly mounted on the top of the top cover 16 .
[0046] In a specific embodiment, the second handle 17 is installed to facilitate installation and removal of the top cover 16 .
[0047] More specifically, the collecting funnel 3 is made of stainless steel. Compared with plastic, the collecting funnel 3 made of stainless steel is strong and durable and not easily corroded.
[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
