Detailed Description

The present invention is further illustrated by the following specific examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the utility model.

A water purifier for cooking water comprises a pre-filter 3, a PP cotton filter 5, an ultrafiltration membrane filter 7, a pre-activated carbon filter 9, an ultraviolet disinfection lamp 8 and a post-filter 6 which are sequentially connected in series.

The inlet of the pre-filter 3 is connected with a tap water pipeline, a water inlet valve 1 is arranged on the tap water pipeline, and a water interception valve 4 is arranged on the pipeline between the ultraviolet disinfection lamp 8 and the post-filter 6. An online differential pressure gauge 2 is arranged between the inlet of the pre-filter 3 and the inlet of the post-filter 6, and an online water quality detector 10 is arranged at the outlet of the post-filter 6.

The ultraviolet disinfection lamp 8 is connected with a 220V alternating current power supply through a transformer 11, and the transformer 11 converts AC220V into DC 24V; the values of the online water quality detector 10 and the online differential pressure gauge 2 are connected to a display screen of the water purifier through a cable; the front filter 3 is internally provided with a front and back double-layer filter screen of 30-40 um; the post filter 6 is internally provided with a resin filter element. A water inlet pipe of DN20 is arranged between the water inlet port of the water purifier and the pre-filter to ensure that the pressure entering the filter element is not lower than 0.35Mpa so as to meet the water supply quantity of the water for cooking and processing.

The working principle of the utility model is as follows:

municipal water enters a pre-filter 3 through a water inlet valve 1, and large particulate matters such as iron rust, silt, insect eggs and the like in water are blocked by a positive and negative double-layer filter screen of 30-40 mu m; the PP cotton filter 5 captures microparticles hidden in water through a self filter layer, so that the next layer of filter element is better protected. The filtered water enters an ultrafiltration membrane filter 7, microorganisms larger than 0.01 micron in the water are separated by the ultrafiltration membrane, so that objects such as microporous colloids and macromolecular organic matters contained in the water are intercepted, and beneficial substances and trace elements in the water flow into a front activated carbon filter 9. The filtered water is sufficiently contacted with the activated carbon when passing through the pre-activated carbon filter 9, and harmful substances such as residual chlorine and chemical residues contained in the water are adsorbed by the activated carbon. Thereby being capable of fully purifying the water source and removing the peculiar smell in the water. The water without peculiar smell enters the ultraviolet disinfection lamp 8, after the water is irradiated by the spectral line generated by ultraviolet, the nucleic acid molecules of the bacteria remained in the water are damaged and continuously split, so that the bacteria can not be bred again. Thereby better protecting the water quality and leading the purified water to have no pollution and no harmful substances. Finally, the sterilized water enters the post-filter 6, the post-filter 6 is internally provided with a resin filter element, and the calcium and magnesium ions in the water source are exchanged by utilizing the micro-fine particle beads in the resin filter element, so that the hardness of the water quality in the water source is reduced. Soften water quality and improve the taste of purified water.

The online differential pressure gauge 2 can monitor the system resistance in real time, and when the filter is used for a long time, the filter element of the filter can accumulate a large amount of impurities to increase the pipe resistance, so that the purified water amount is reduced; when the pipe resistance is increased to an alarm value, the working personnel is reminded to replace the filter element in time, and the use of cooking water is guaranteed. Meanwhile, the online water quality detector 10 can monitor the water quality change in real time, thereby ensuring the healthy use of cooking water.

pp cotton, ultrafiltration, resin filters are normally on the market with a length of 20 cm and a diameter of 6 cm. The filter element adopted by the water purifier has the length of 50 cm and the diameter of 6 cm, the filtering area is enlarged by about 1.5 times, the water flow is enhanced, and the length of the filter element is more than one time of that of a common filter element. The filter element is connected with the water utilization equipment by the four-way water pipe after filtration, and the flow speed of the purified water can be increased to 3.45m³The water consumption and water concentration problems in food processing are met.

After the tap water is purified, a detection report shows that 6 substances such as cyanide, hexavalent chromium, manganese, arsenic, total escherichia coli, heat-resistant escherichia coli and the like are not detected, indexes of other substances are reduced after the other substances are purified, and the water purification effect is obvious.

The cooking water purifier is customized according to the site space position of a catering operation room, so that the space utilization is maximized, and the environment layout is beautified.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the spirit of the utility model, and these changes and modifications are all within the scope of the present invention.
