Description

Technical Field

[0001] This utility model relates to the technical field of laboratory equipment, specifically a splash-proof water tank for chemical laboratories. Background Technology

[0002] In current chemical labs, water tanks often experience splashing if the flow rate isn't properly controlled. Chemical experiments frequently involve toxic, harmful, corrosive, or irritating chemicals. If the water flow in the tank is too rapid, these chemicals could splash onto personnel, equipment, or other areas of the lab, increasing safety risks. Splash-proof designs effectively reduce the occurrence of these accidents.

[0003] In chemical or pharmaceutical experiments, various reagents and samples often need to be strictly separated. Water splashes in the sink can contaminate reagents, chemicals, drug samples, or laboratory equipment, affecting the accuracy of experimental results and even damaging the reliability of samples or data. A rapid water flow can contaminate laboratory surfaces, equipment, and floors, increasing the difficulty of cleaning and maintenance, especially after chemical or pharmaceutical spills, which may require special treatment or even specialized cleaning agents or equipment.

Float chambers are provided on both sides of the tank body, and fixed lugs are provided at both ends of each float chamber. Vertically upward support columns and limiting plates that horizontally connect the two float chambers are provided on the fixed lugs. The support columns at both ends of the float chambers are connected by a fixed plate, and a buffer layer is provided above the fixed plate.

[0005] Furthermore, a drainage pipe is provided outside the water outlet, and a valve is provided on the drainage pipe.

[0006] Furthermore, the buffer layer is a mesh grid structure.

[0008] Furthermore, the specifications of the mesh plate are square holes of 1×1 to 5×5 mm and a thickness of 3 to 5 mm.

[0009] Furthermore, the height of the mesh grid plate from the bottom of the trough is ≤ 1 / 2 of the height of the trough.

[0010] Furthermore, the top of the groove is surrounded by an outwardly extending mounting plate.

[0011] The beneficial effects of this utility model are: 1. Through the design of the tank and the cooperation of the filter funnel and filter screen, liquid splashing can be effectively blocked, reducing the pollution and impact of liquid splashing on the surrounding environment during the experiment. The design of the floating tank allows it to float automatically according to the liquid level. Combined with the fixing effect of the support column and the limiting plate, the stability and position accuracy of the floating tank are ensured; 2. The fixed plate and the buffer layer work together to effectively alleviate the impact force generated when liquid splashes, avoiding damage to equipment and personnel, and improving the safety of the laboratory; The stainless steel, glass fiber, aluminum alloy or PVC materials used have excellent corrosion resistance and high temperature resistance, which are suitable for the treatment of various chemical substances in chemical laboratories, ensuring the stability of the equipment for long-term use.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Combination Figure 1 As shown in Figure 3: A splash-proof water tank for a chemical laboratory includes a tank body 1, with a water outlet 2 at the bottom of the tank body 1 for draining accumulated water, and a drain pipe 12 outside the water outlet 2. A valve is provided on the drain pipe 12 for controlling the discharge of accumulated water in the tank.

[0016] The outlet 2 is surrounded by an annular mounting groove 3 for installing a funnel. The mounting groove 3 contains a filter funnel 4, and the bottom of the filter funnel is equipped with a filter screen 5 for further filtration of the water. Both sides of the tank 1 are equipped with float chambers 6, which are generally made of plastic, such as polypropylene, and are hollow inside to provide buoyancy. The float chambers 6 are equipped with fixed lugs 7 at both ends. The fixed lugs 7 are equipped with vertically upward support columns 8 and horizontally connected limiting plates 9 to restrict the float chambers from getting close to each other. The support columns 8 at both ends of the float chambers 6 are connected by a fixed plate 10 to support the buffer layer 11 set above the fixed plate 10.

[0017] The buffer layer 11 is a grid structure, and the material can be stainless steel, fiberglass, aluminum alloy, or PVC, polypropylene, or high-density polyethylene (HDPE) to meet the needs of laboratory water tanks.

[0018] The specifications of the mesh grating are square holes of 1×1~5×5mm and a thickness of 3~5mm. The appropriate size provides sufficient strength and splash protection.

[0019] The height of the grating plate from the bottom of the tank should be less than or equal to half the height of the tank body 1 to prevent the water flow from getting too close to the grating plate.

[0020] The top of the tank 1 is surrounded by an outwardly extending mounting plate 13, which facilitates the installation of the tank 1.

[0021] Working principle: When water is injected into the tank, it is dispersed by the mesh grid to prevent splashing. When water accumulates in the tank, the floating hopper causes the mesh grid to rise, preventing the water level from rising and overflowing the mesh grid for further splashing. The accumulated water can be discharged by opening and closing the valve. The outflowing liquid is further filtered through the filter screen to ensure the removal of solid waste. The limiting plate limits the position of the floating hopper, ensuring that the mesh grid bends and contracts inward after being impacted by the water flow, thus affecting the anti-splashing effect.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
