TECHNICAL FIELD
[0001] The utility model belongs to the technical field of laboratory apparatus, and particularly relates to a pure water storage barrel for student analytical chemistry laboratory. BACKGROUND
[0002] Analytical chemistry experiments have high requirements for experimental water, and purified water needs to be used, otherwise impurity ions in the water will have adverse effects on experimental results.
[0003] Because the pure water machine has slow water output, under normal circumstances, laboratory staff will prepare pure water in advance and store the pure water in a pure water storage barrel with a large volume, and when experiments are carried out, the pure water in the storage barrel is connected to a small water bucket and directly used for student experiments.
[0004] The experimental work of a student laboratory is stage-based, and after the experimental content of a semester is completed, experiments need to be stopped during the winter and summer vacations. Before the holidays, laboratory staff need to drain the water in the water bucket, otherwise algae and bacteria will breed in the water bucket and affect the subsequent experiments.
[0005] For a small water bucket in a laboratory, as long as it is inverted, the remaining water in the bucket can be safely drained, and the holidays can be safely spent. However, for a pure water storage barrel in a laboratory, because of its large volume, it is difficult to perform the inversion and drainage operation. The faucet of the pure water storage barrel is generally located at the bottom of the outer wall of the barrel body, but the faucet is a certain distance from the bottom of the barrel body, so the remaining pure water in the storage barrel cannot be completely drained from the faucet. Laboratory staff can only tilt the storage barrel to one side of the faucet to slowly drain the remaining water from the faucet, which is very inconvenient, and the remaining water is not easy to drain completely. SUMMARY
[0006] The technical problem to be solved by the utility model is to provide a pure water storage barrel for student analytical chemistry laboratory, which can make the remaining pure water in the storage barrel be drained completely by gravity through the reasonable addition of a water outlet, and avoid the breeding of algae and bacteria in the barrel during the winter and summer vacations.
[0007] To solve the above technical problems, the utility model adopts the following technical scheme:
[0008] A pure water storage barrel for student analytical chemistry laboratory, comprising a barrel body, a barrel cover and a faucet, wherein the bottom surface of the barrel body is provided with an annular base and a water outlet.
[0009] Further, the center of the annular base coincides with the center of the barrel body, and the radius of the annular base is 0-5 cm smaller than the radius of the barrel body.
[0010] Further, the water outlet is 2-5 cm away from the annular base.
[0011] Further, the water outlet is provided with a bottom cover, the outer wall of the water outlet is provided with external threads, the inner wall of the bottom cover is provided with internal threads, and the external threads and the internal threads are matched.
[0012] Further, the bottom cover is internally provided with a rubber pad.
[0013] Further, the height from the bottom surface of the barrel body to the top of the bottom cover is less than the height of the annular base.
[0014] Further, the pure water storage barrel is made of plastic.
[0015] Compared with the general pure water storage barrel, the utility model adds a water outlet on the bottom surface of the barrel body, after the experimental work in each semester is finished, the laboratory staff can first drain the remaining water in the barrel from the water faucet, when the water level is lowered below the water faucet, the bottom cover of the water outlet can be unscrewed, due to the gravity, the remaining water in the barrel will be automatically drained from the water outlet. The setting of the water outlet on the bottom surface of the barrel body can make the remaining water in the barrel be completely drained, and during the drainage, the laboratory staff can carry out other work, without having to hold the inclined water storage barrel with water all the time, the work intensity is reduced.
[0016] After the drainage is completed, the bottom cover does not have to be immediately covered back, under the condition that the drainage opening on the bottom of the barrel body and the barrel cover on the top of the barrel are both open, the air in the barrel forms a convection, which is beneficial to accelerate the drying of the inner wall of the water barrel, and can further prevent the breeding of algae and bacteria in the barrel. When the pure water is prepared at the beginning of the next semester, the bottom cover can be covered back to the water outlet.
[0017] The setting of the water outlet on the bottom of the barrel body is also beneficial to the washing of the pure water storage barrel. For the general pure water storage barrel, if the washing sewage is drained from the water faucet, the water faucet is very easy to be blocked due to the possible solid impurities in the washing sewage, if the washing sewage is drained from the barrel cover outlet on the top of the barrel, the barrel has to be inverted, which is very difficult to operate for the pure water storage barrel with a large volume. Using the storage barrel proposed by the utility model, the washing sewage can be easily drained from the water outlet, so that the washing work can be easily carried out.
[0018] The radius of the annular base is 0-5cm smaller than the radius of the barrel body, and the water outlet is 2-5cm away from the annular base. The radius of the annular base is equal to or slightly smaller than the radius of the barrel body, so that the barrel body is stably seated on the base and is not easy to be tilted. The water outlet is located on the barrel bottom close to the annular base, when the remaining pure water in the barrel is drained, as long as the storage barrel is slightly moved, the water outlet can be put out of the table surface on which the pure water barrel is placed, at this time, the outlet can be directed to the water groove, so that the water is drained into the water groove, or a water receiving container is placed on the ground close to the table surface, so that the water outlet is directed to the water receiving container, so that the water is drained into the water receiving container. In addition, the water outlet and the base are kept at a proper distance, when the bottom cover is unscrewed and screwed back by hand, the operation of the fingers is left with space, so that the base does not block the fingers.
[0019] The bottom cover and the water outlet are connected by threads, and the cover is provided with a rubber pad, so that the water tightness of the bucket is enhanced, and water leakage is prevented.
[0020] The height from the bottom of the bucket body to the top of the bottom cover is less than the height of the annular base, so that when the bucket is placed on a table surface such as an experiment table, the water outlet does not collide with the table surface, and the water outlet does not hinder the stable placement of the bucket on the experiment table.
[0021] The pure water storage bucket is made of plastic. Plastic is light in weight and low in price, so that the production cost is low, and the movement of the storage bucket is facilitated. In addition, the plastic material has a certain transparency, so that the water level in the bucket can be distinguished from the appearance of the bucket, and the preparation and use of pure water are facilitated.
[0022] Thanks to the above technical solutions, the technical progress achieved by the utility model is:
[0023] (1) The utility model sets the water outlet at the bottom of the bucket body, so that the remaining water in the bucket can be completely drained from the water outlet, preventing the breeding of algae and bacteria in the bucket. During the drainage, the remaining water in the bucket can flow out naturally by gravity, so that laboratory workers do not have to tilt the water storage bucket all the time, reducing the working intensity.
[0024] (2) The drainage port at the bottom of the bucket body and the bucket cover outlet at the top of the bucket body form a convection of air in the bucket, which is beneficial to the rapid drying of the inner wall of the bucket.
[0025] (3) The water outlet facilitates the washing work of the inner wall of the storage bucket, and the sewage after washing can be easily drained from the water outlet. BRIEF DESCRIPTION OF DRAWINGS
