Description

Technical Field

[0001] The invention relates to the technical field of liquid pouring equipment, in particular to a chemical liquid splash-proof pouring device. Background Art

[0002] The chemical liquid pouring device plays a vital role in the preparation of chemical raw liquid. Its main function is to safely and accurately pour the barreled chemical raw liquid into the designated raw liquid tank to ensure the smooth progress of the production process and avoid harm to the environment or personnel. The structure of this type of device usually includes a support frame, a tilting mechanism, a liquid conduit, a valve, and a flow control device. The support frame is used to support the entire device and adjust the pouring angle. The tilting mechanism adjusts the tilt angle of the barrel through manual, hydraulic or electric drive to allow the liquid to be poured smoothly into the tank. The liquid conduit connects the barrel and the raw liquid tank. The flow control device and valve are used to accurately adjust the liquid flow rate to avoid liquid overflow or waste. For example, a liquid dumping device disclosed in the authorization announcement number CN214878602U includes: a bracket, a rotating shaft is provided on the top; a placing plate for placing the liquid barrel, the top of which is connected to the rotating shaft, and a support rod is provided at the bottom. The rotating shaft is set on the top of the bracket, and the placing plate is connected to the rotating shaft. The liquid barrel is placed on the placing plate, and the placing plate is rotated upward with the rotating shaft as the center, so that the liquid barrel has a dumping angle, and the liquid is dumped into the liquid holding device. However, the above technical solution still requires the operator to dump the liquid barrel through the support rod, the rotating shaft and other components during use. It is relatively easy to operate for low-volume liquid barrels, but it is difficult to operate for larger-volume chemical liquid stock barrels, especially chemical stock barrels of 25 kg or more. Operators need to have a certain amount of physical strength to successfully complete the dumping operation. Although components such as the support frame and the rotating shaft can help adjust the angle to a certain extent, for heavy liquid barrels, relying on manual power to tilt and rotate the barrel is still an extremely labor-intensive process. In the process of dumping chemical raw liquid, the gravity of the barrel and the inertia of the liquid will cause the barrel to shake violently during dumping, and even fall off the bracket. Once the barrel falls off, the chemicals will splash out of the raw liquid tank, increasing the risk of chemical leakage, thereby endangering the safety of the operator. In addition, manual control is often difficult to achieve accurate flow regulation when facing large-capacity raw liquid barrels, which can easily lead to excessively fast or slow liquid flow during the dumping process, resulting in overflow or residual raw liquid in the barrel. Summary of the invention

[0003] The object of the present invention is to provide a chemical liquid splash-proof dumping device, which places a large-volume raw liquid barrel for the chemical raw liquid to be dumped on a supporting frame, and uses an opposing ladder clamping module to clamp and fix the raw liquid barrel.

The entire dumping process ensures efficient and accurate pouring of liquid, especially when handling large-volume chemical liquid barrels. It can not only reduce the labor intensity of operators, but also ensure accurate control of liquid and safe protection of the environment during the dumping process; Among them, using the opposite ladder clamping module to fix the raw liquid barrel can effectively avoid the instability of the barrel body caused by gravity or liquid inertia during the dumping process. Especially for large-volume barrels of 25 kg and above, the fixing mechanism can ensure the stability of the barrel body during the dumping process, reduce the liquid splashing caused by the barrel body falling off or shaking, thereby significantly reducing the risk of chemical leakage or injury to operators. The combination of the support frame and the opposite ladder clamping module makes the center of gravity of the raw liquid barrel more stable during the dumping process, which can not only prevent the raw liquid barrel from falling off, but also reduce the risk of muscle strain or accidents caused by excessive reliance on limb strength. By introducing the gear-type hydraulic tipping module, the raw liquid barrel can be quickly dumped in a short time. It can be driven by hydraulic pressure to provide stable and powerful dumping power. At the same time, according to different needs, it can quickly dump at an angle of 95 degrees or slowly dump at an angle of 40 degrees. The fast dumping part is suitable for the initial pouring of chemicals in the raw liquid barrel, while the slow dumping can ensure the accurate pouring of the remaining liquid to avoid overflow or waste. It solves the high dependence on manual force when dumping large-volume barrels and avoids the fatigue of operators caused by repeated exertion, thereby improving the overall operating efficiency. The risk of chemicals splashing out of the tank is effectively reduced by designing the splash shield in the raw liquid tank and the lifting side shield splash shield modules on both sides of the support frame. These splash shield modules form barriers in time during the pouring process to effectively guide the possible splashed liquid back to the raw liquid tank, avoiding potential harm to equipment, environment and operators caused by splashed liquid.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1, by Figures 1 to 4 The present invention comprises a main frame 1, a raw liquid tank 2 for containing chemical liquid is installed on the inner wall of one side of the main frame 1, and splash shields 4 for forming a gap for the flow of chemical liquid with the bottom of the raw liquid tank 2 are fixed on both sides of the interior of the raw liquid tank 2; T-shaped slide arm 5, two T-shaped slide arms 5 are provided, and the two T-shaped slide arms 5 are slidably mounted on the inner wall of the other side of the main frame 1, a support plate 6 is fixed on the outer wall of the side of the T-shaped slide arm 5 close to the stock liquid tank 2, two dovetail guide rails are fixed on the inner wall of one side of the main frame 1, and sliding sleeves for slidingly cooperating with the dovetail guide rails are fixed at the corner positions on the back of the T-shaped slide arm 5, and triangular reinforcement plates are installed on the outer walls of both sides of the T-shaped slide arm 5; A support frame 8 for supporting the raw liquid barrel is arranged between the two support plates 6. The support frame 8 adopts a solid steel structure design and can bear raw liquid barrels of different volumes and weights. A gear-type hydraulic flip module 7 for driving the support frame 8 to tip over and allow the raw liquid barrel to inject liquid into the raw liquid tank 2 is installed on the outer wall of one of the support plates 6. Opposite ladder clamping modules 9 for limiting the raw liquid barrel are installed on the outer walls of both sides of the support frame 8. The lifting side shield splash-proof module 11 is arranged on the other two inner walls of the supporting frame 8. The lifting side shield splash-proof module 11 is located on both sides of the supporting frame 8 and can be automatically lifted and lowered according to the change of the tipping angle. When the stock liquid barrel is tipped to a certain angle, the lifting side shield splash-proof module 11 will automatically rise to form a barrier to further prevent liquid from splashing. The design of this module can prevent liquid from splashing and does not affect the smoothness of the liquid flowing into the stock liquid tank, thereby ensuring the safety of the operation process; A PLC control panel 10 electrically connected to the input ends of the gear-type hydraulic flip module 7, the opposite ladder opening clamping module 9, and the lifting side shield splash-proof module 11 is installed on one side outer wall of the main frame 1; The distance between the two splash shields 4 is 100 cm to 150 cm. A splash shield 101 is fixed on the outer wall of the main frame 1 on one side of the stock liquid tank 2. A drain valve 3 is installed on one side of the outer wall of the stock liquid tank 2. The setting of the drain valve 3 facilitates the staff to take the chemical stock solution in the stock liquid tank 2. The main frame 1, the splash shield 101, and the splash shield 4 are all made of stainless steel components. The splash shield 4 installed in the stock liquid tank 2 can prevent the liquid from splashing outside the tank when the chemical liquid is poured into the tank. Especially when the liquid is poured at a fast speed, the splash shield 4 guides the liquid into the tank, effectively reducing the pollution and safety hazards caused by liquid splashing. Since there is a gap between the bottom edge of the splash shield 4 and the bottom of the stock liquid tank 2, the gap allows the stock liquid barrel to flow to both sides of the stock liquid tank 2.

[0019] Embodiment 2, based on embodiment 1, Figure 5 and Figure 6The gear-type hydraulic flip module 7 includes a cylinder seat 701 fixed on the outer wall of one side of the support plate 6, a hollow shaft box 703 fixed on the outer wall of the support plate 6 on one side of the cylinder seat 701, a transmission shaft 704 rotatably installed inside the hollow shaft box 703, and a rotating shaft 706 rotatably installed on the outer wall of the support plate 6 on one side of the transmission shaft 704. The end of the rotating shaft 706 away from the support plate 6 is fixedly connected to the outer wall of one side of the support frame 8. A gear speed-increasing transmission structure 705 is installed between the transmission shaft 704 and the rotating shaft 706. A first hydraulic cylinder is installed on the top of the cylinder seat 701. 702, the bottom end of the piston rod of the first hydraulic cylinder 702 penetrates the outside of the cylinder seat 701 and is installed with a gear rack transmission structure 707 for driving the transmission shaft 704 to rotate. The first hydraulic cylinder 702 drives the gear rack transmission structure 707 to drive the transmission shaft 704 in the hollow shaft box 703 to rotate, and then the transmission shaft 704 drives the rotating shaft 706 to rotate through the gear speed increase transmission structure 705. At this time, the rotating shaft 706 will actively drive the support frame 8 to deflect and make the raw liquid barrel tip over, and the barrel body is tilted by hydraulic power to control the tipping angle and speed; The gear rack transmission structure 707 includes a rectangular cross seat fixed at the bottom end of the piston rod of the first hydraulic cylinder 702, a round rack fixed at the top end of the rectangular cross seat, and a first-stage gear fixed on the surface of the transmission shaft 704. The first-stage gear is located inside the hollow shaft box 703, and the top end of the round rack penetrates the outside of the hollow shaft box 703 and meshes with the first-stage gear. The gear design can provide a stronger turning force to meet the dumping requirements of large-volume chemical stock liquid barrels, ensuring that the large-volume dumping task can be completed efficiently. The gear speed-increasing transmission structure 705 includes a driving toothed disc 7051 fixed at one end of the transmission shaft 704 and a driven gear 7052 fixed at one end of the rotating shaft 706. The driving toothed disc 7051 and the driven gear 7052 are meshed with each other. The outer diameter of the driving toothed disc 7051 is two to six times the outer diameter of the driven gear 7052. The gear speed-increasing transmission structure 705 formed by the driving toothed disc 7051 and the driven gear 7052 can make the rotating shaft 706 rotate more times, helping the supporting frame 8 and the raw liquid barrel to obtain a larger pouring angle.

[0020] Embodiment 3, based on embodiment 2, Figure 7 and Figure 8It is given that the opposed ladder-mouth clamping module 9 can also adapt to raw liquid barrels of different sizes and shapes, and provide stable support and fixation for different types of barrels. The opposed ladder-mouth clamping module 9 includes a screw electric linear module 901 fixed on the two opposite outer walls of the support frame 8, a slide 902 installed at the moving end of the screw electric linear module 901, and a support beam 903 fixed at the top of the slide 902. The top of the support beam 903 is fixed with a ladder-shaped opening frame 904 for contacting the outer wall of the raw liquid barrel. The two screw electric linear modules 901 are mirror-symmetrical structures about the vertical center reference plane of the support frame 8. One side outer wall of the slide 902 is in contact with the support frame 8. The outer wall of one side of the original liquid barrel is slidably matched. After the original liquid barrel is placed on the top of the supporting frame 8, the original liquid barrel will be located between the two trapezoidal opening frames 904. The staff starts the work of the screw electric linear module 901 through the PLC control panel 10. The two mirror-symmetrical screw electric linear modules 901 work synchronously, and the screw electric linear module 901 drives the slide 902, the support beam 903 and the trapezoidal opening frame 904 to slide until the two trapezoidal opening frames 904 approach each other and contact and clamp with the outer wall of the original liquid barrel, so as to firmly fix the barrel body on the supporting frame 8, to ensure that the barrel body will not be displaced during the dumping process, to avoid danger; Rectangular protrusions are integrally formed on the two inner walls of the trapezoidal open frame 904 . The rectangular protrusions formed on the two inner walls of the trapezoidal open frame 904 are used to contact the barrel top to prevent the raw liquid barrel from sliding out from between the two trapezoidal open frames 904 .

[0021] The lifting side shield splash-proof module 11 comprises a steel plate 1101 installed on the other two side outer walls of the supporting frame 8, a second hydraulic cylinder 1102 installed on the outer wall of the steel plate 1101 close to the supporting frame 8, and a second baffle 1103 fixed at the top end of the piston rod of the second hydraulic cylinder 1102, the top end of the second baffle 1103 extends upward to the outside of the supporting frame 8, and the second baffle 1103 is located on one side of the ladder-shaped opening frame 904. Two guide seats 1104 are fixed on the adjacent outer walls of the two steel plates 1101, and a guide rod 1105 is slidably installed inside the guide seat 1104. The top end of the guide rod 1105 is fixedly connected to the bottom end of the second baffle 1103, and a straight slot connecting beam 1106 is installed between the top ends of the two guide rods 1105 in the same X-axis direction; During the pouring process of chemical liquid, especially when pouring quickly, the liquid has strong fluidity and is prone to splashing. The splash-proof baffle 4 effectively guides the liquid to flow into the original liquid tank to prevent the liquid from splashing to the outside and causing safety hazards or polluting the environment. At this time, the staff uses the PLC control panel 10 to start the second hydraulic cylinder 1102 to work, and the second hydraulic cylinder 1102 drives one of the second baffles 1103 to move up and is located on one side of the barrel body. The second baffle 1103 will drive the guide rod 1105 to slide upward inside the guide seat 1104, and the guide rod 1105 and the second baffle 1103 on the other side will also move up synchronously driven by the straight groove connecting beam 1106. At this time, there is a second baffle 1103 on both sides of the barrel body, which plays an additional protective role, effectively prevents liquid splashing, and keeps the pouring process clean and safe.

[0022] Before the dumping operation begins, in the embodiment of the present application, the large-volume chemical liquid barrel needs to be correctly placed on the support frame 8. The function of the support frame 8 is to support the weight of the barrel body to ensure that the barrel body does not accidentally slip during the dumping process. Then, the PLC control panel 10 is used to turn on the opposite ladder clamping module 9 to work. The opposite ladder clamping module 9 clamps and fixes the liquid barrel. The opposite ladder clamping module 9 uses two opposite clamping parts and tightens them electrically to firmly fix the barrel body in the support frame 8 to prevent the barrel body from slipping during the dumping process. In case of displacement or slippage, after the raw liquid barrel is fixed, the dumping operation can begin. The gear-type hydraulic flip module 7 provides stable and powerful power through the external hydraulic system to drive the raw liquid barrel to tilt as a whole. In this process, the external hydraulic system and the opening time of the switch valve can be used to accurately control the dumping angle, thereby realizing the adjustment of fast dumping or slow dumping. At this time, the gear-type hydraulic flip module 7 is turned on through the PLC control panel 10 to work. The gear-type hydraulic flip module 7 first forces the supporting frame 8, the opposite ladder clamping module 9, and the lifting side guard splash guard to move. The module 11 and the stock liquid barrel are quickly tilted to an angle of ninety-five degrees. This pouring mode is suitable for the initial pouring of the chemical liquid in the stock liquid barrel, and can quickly discharge most of the liquid into the stock liquid tank 2 below. When most of the liquid is poured out, the pouring angle will be adjusted to forty degrees. This pouring mode helps to ensure that the final liquid can be accurately poured into the stock liquid tank to avoid splashing or waste of liquid due to excessive flow rate. During the pouring process, the splash guard 4 in the stock liquid tank 2 and the lifting side shield splash guard module 11 on both sides of the support frame 8 form an anti-splash mechanism to ensure that the liquid is poured into the stock liquid tank 2. Even if fluctuations occur during pouring, they can be effectively controlled in the stock liquid tank. In the final stage of the pouring process, the liquid is almost completely poured out. At this time, the tilt angle of the stock liquid barrel is adjusted to an appropriate position so that the last chemical liquid in the barrel can be accurately poured into the stock liquid tank 2. Once the liquid is completely poured into the stock liquid tank 2, the gear-type hydraulic flip module 7 will restore the stock liquid barrel to its initial position. At this time, the opposing ladder clamping module 9 will release the stock liquid barrel, allowing the barrel body to be taken out or further processed. The staff completes the final cleaning work to ensure the cleanliness and safety of the device.
