Description

Technical Field

[0001] The present application relates to the technical field of glass bottle washing, and in particular to a glass bottle washing machine. Background Art

[0002] Glass bottles are widely used in food, medicine, cosmetics and other industries due to their good chemical stability. At the same time, glass bottles are also recyclable, which is beneficial to environmental protection and sustainable development. Because the bottle must be clean before use, it is necessary to clean and dry the glass bottle in advance.

[0003] Nowadays, glass bottles are basically cleaned by machine cleaning. Machine cleaning can improve cleaning efficiency, ensure cleaning quality, reduce labor costs and the risk of human error, but machine cleaning will use a lot of clean water, which will cause the problem of water resource waste.

[0050] Example 2

[0051] Reference Figure 1 , Figure 4 and Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0052] A partition 81 is provided in the cache water tank 4, and the partition 81 divides the cache water tank 4 into two parts, which are respectively called an oil-water separation chamber and a water transfer chamber. The oil-water separation chamber is connected to the tapered water collecting tank, and the water transfer chamber is connected to the circulating water suction port of the circulating water pump 5; a pipeline connecting the oil-water separation chamber and the water transfer chamber is provided on the partition 81, which is called a water transport pipeline 82; the distance between the port of the water transport pipeline 82 in the oil-water separation chamber and the bottom of the oil-water separation chamber is 10-20cm; the distance between the other port of the water transport pipeline 82 in the water transfer chamber and the bottom of the water transfer chamber is 35-45cm; the oil-water separation chamber is also provided with at least two sewage outlets, one sewage outlet is 0-5cm away from the bottom of the oil-water separation chamber; the other sewage outlet is 50-55cm away from the bottom of the oil-water separation chamber; by providing the partition 81, a water transport pipeline 82 is provided on the partition 81, the water transport pipeline 82 is below the port of the oil-water separation chamber and above the port of the water transfer chamber, when the taper water collecting tank is When sewage is injected into the oil-water separation tank, the silt and impurities in the sewage in the oil-water separation tank will sink, and the oil will float up. The relatively clean water in the middle flows into the water transfer tank from the water transport pipe 82, and the water transport pipe 82 is close to the port of the water transfer tank, so as to prevent a large amount of water containing oil and dirt from flowing into the water transfer tank during the filling process of the oil-water separation tank, and to ensure that the water in the water transfer tank will not flow back into the oil-water separation tank, thereby improving the oil-water separation effect. Two sewage outlets are provided, and the upper sewage outlet is often opened to continuously discharge oil and dirt, so as to facilitate collection and centralized treatment, and avoid the accumulation of oil and dirt affecting the oil-water separation effect. The lower sewage outlet is often closed and opened to discharge silt and impurities when silt is accumulated, so as to uniformly collect and centrally treat the cleanliness of the water in the water transfer tank, and when the water level is too high, it flows out from the upper sewage outlet to prevent it from flowing out of the tank body due to overfilling. When the water circulation system circulates water, the cleanliness of the water is guaranteed, the cleaning effect of the spray pipe 3 is guaranteed, the recycling of water is realized, and the environmental protection performance of the cleaning machine is improved.

[0053] A transparent liquid level tube is provided in the water transfer tank to facilitate observation of the amount of liquid in the water transfer tank. If the water level in the water transfer tank is too low, the circulating water pump 5 is turned off.

The distance between the bottom of the float 83 and the bottom of the oil-water separation chamber is 35-55 cm. By setting the float 83 and connecting the plug 84 under the float 83, when the liquid level in the oil-water separation chamber reaches the height of lifting the float 83, the float 83 pulls out the plug 84 to open the end of the water transport pipe 82, so as to prevent oil from entering the water transport chamber through the water transport pipe 82 during the rising process of the liquid level in the oil-water separation chamber. When the plug 84 is opened, the water transport pipe 82 can directly extend into the cleaner water in the middle layer of the water layer, thereby improving the separation effect of oil and sediment, ensuring the recycling of water, and improving the environmental protection performance of the cleaning machine.

[0055] During use, when the conical water collection trough injects the collected sewage into the oil-water separation chamber of the buffer water tank 4, the liquid level in the oil-water separation chamber gradually rises, and the oil on the cleaned glass bottle floats above the liquid level, and the mud or other impurities sink into the oil-water separation chamber until the liquid level rises to lift up the float 83, and the float 83 pulls out the plug 84, and the water transport pipe 82 transfers the clean water in the middle of the liquid surface in the oil-water separation chamber to the water transfer chamber. The upper sewage outlet is often open to continuously discharge oil, which is convenient for collection and centralized treatment, avoiding the accumulation of oil and affecting the oil-water separation effect. The lower sewage outlet is often closed and opened to discharge mud and impurities when mud and sand are accumulated, which are uniformly collected and centralized for treatment, to ensure the cleanliness of the water in the water transfer chamber, thereby ensuring the recycling of water and improving the environmental protection performance of the cleaning machine.
