Description

Cleaning device

Technical Field

The utility model relates to a belt cleaning device technical field, especially lithium cell production facility's belt cleaning device.

Background

In a production line of a lithium battery with annual production of 3GWH, a set of pure water preparation device is used for providing ultrapure water for homogenizing a cathode of a workshop, simultaneously providing water for a boiler and providing water for cold water, hot water and process circulating water. During the operation process, the RO reverse osmosis membrane group serving as a core device for removing ions in water gradually scales, and the system water-making capacity can be restored only by chemically cleaning the device. The cleaning liquid for chemical cleaning needs to be prepared by first-level RO water production.

The existing cleaning device, a water supplementing technical scheme, is to install a DN65 pipeline 1 at a water producing end of a first-level RO to supplement water to a chemical cleaning box 2, and refer to fig. 1. Because the chemical cleaning generally needs two steps of acid cleaning and alkali cleaning, and each step needs at least one water replenishing, the technical scheme is that the first-stage RO device needs to normally operate to replenish water during water replenishing, so that the whole cleaning process cannot be continuously performed; the cleaning effect is influenced and the cleaning frequency is increased because the system needs to interrupt cleaning for many times in the midway during the cleaning process and then is switched to normal operation; the normal operation of the system requires the operation of all the equipment of the whole primary RO reverse osmosis system, so the operation cost of the cleaning process is increased.

In the existing cleaning device, another water supplementing technical scheme is that 1 special water supplementing pump 4 is installed at a first-stage RO water tank 3, a special pipeline is laid to a chemical cleaning water tank 2, and water is delivered from the first-stage RO water tank 3 to the cleaning water tank 2, and the water supplementing pump is shown in fig. 2. The special water replenishing pump 4 is added in the technical scheme, so that the cleaning cost is increased; according to the current situation of the device, the number of times of chemical cleaning of the equipment is estimated to be 1-2 times every year, and the utilization rate of the special water replenishing pump 4 is very low; because the area of the whole water treatment room is small, the arrangement of the existing equipment is already very narrow, and the arrangement and installation are difficult if the water replenishing pump 4 is additionally arranged.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

The cleaning apparatus in this embodiment is an improvement over the existing cleaning apparatus, and both have substantially the same structure, as shown in fig. 3, and each include a cleaning water tank 2, a primary RO water tank 3, and an external RO feed water pump 5 connected to the primary RO water tank through a pipe. The cleaning device in the embodiment is improved in that a water replenishing branch pipe 6 is connected between the cleaning water tank 2 and an outlet of an external RO water feeding pump 5, and cleaning water is replenished to the cleaning water tank 2 through the water replenishing branch pipe 6.

Since the refill manifold 6 is used frequently (1-2 times/year) every year, it is preferable that the refill manifold 6 is a plastic hose. In the present embodiment, DN32-UPVC plastic hose is more preferable. The length of the water replenishing branch pipe 6 is 15 meters. Because the length of moisturizing branch pipe 6 is longer, considers the problem of pipeline joint strength, then DN32-UPVC transparent plastic steel wire net hose as moisturizing branch pipe 6, has had the wire net then to promote the bulk strength of hose, and at the in-process of long distance transport washing water, moisturizing branch pipe 6 can not be broken.

The two ends of the water replenishing branch pipe 6 are respectively connected with a connecting pipe 7, that is, one connecting pipe 7 is connected with one end of the water replenishing branch pipe 6, and the other connecting pipe 7 is connected with the other end of the water replenishing branch pipe 6. One connecting pipe 7 is connected with the cleaning water tank 2, and the other connecting pipe 7 is connected with the outlet of the external supply RO water feeding pump 5. The connecting pipes 7 on the two ends of the water replenishing branch pipe 6 are all 1 meter long. As the water replenishing branch pipe 6 is a DN32-UPVC transparent plastic steel wire mesh hose, the connecting pipe 7 is a DN32-UPVC plastic hard pipe. The water replenishing branch pipe 6 is connected with the connecting pipe 7 through a quick coupler 9. As the water replenishing branch pipes 6 are DN32-UPVC transparent plastic steel wire mesh hoses and the connecting pipes 7 are DN32-UPVC plastic hard pipes, the corresponding quick connectors 9 are DN32-UPVC plastic quick connectors. Accomodate moisturizing branch pipe 6 at ordinary times, a connecting pipe 7 is connected on wasing water tank 2, and another connecting pipe 7 is connected on the export of outer supply RO water feeding pump 5, during chemical cleaning, can realize the quick installation between moisturizing branch pipe 6 and two connecting pipes 7 through with quick-operation joint 9.

As shown in fig. 3, a ball valve 8 is installed on a connection pipe 7 connected to an outlet of the RO feed water pump 5. Since the connecting pipe 7 is a DN32-UPVC plastic hard pipe, the ball valve 8 is correspondingly a DN32-UPVC ball valve. The ball valve 8 can control the opening and closing of the water replenishing branch pipe 6, and further can control the replenishing of the cleaning water.

The cleaning device provides a water replenishing scheme for realizing efficient chemical cleaning under the conditions that the equipment is arranged in a narrow place and the scale of the RO device is not large.

The cleaning device provided by the embodiment keeps the continuity of the chemical cleaning process, indirectly improves the chemical cleaning effect, reduces the investment cost and the chemical cleaning operation cost of the cleaning device to the maximum extent, and indirectly eliminates the inconvenience caused by the installation of newly-added equipment.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
