Description

Technical Field

[0001] The utility model relates to water treatment equipment, in particular to an inlet water pretreatment device of a water purification equipment. Background Art

[0002] Water purification equipment, in simple terms, is equipment that produces purified water. It is mainly used to remove impurities, bacteria, viruses and other harmful substances in the water so that the water meets the standards for drinking or industrial water. Water purification equipment is widely used in the fields of drinking, chemical, medical, breeding, planting, food, beverages, etc. In order to extend the service life of the water purification equipment, a pretreatment device is usually set at the front end of the water inlet of the water purification equipment. The main purpose of the pretreatment device is to remove large particles of impurities, suspended matter, organic matter and other impurities in the water, providing a good foundation for the subsequent water treatment process. Simply put, the pretreatment device is the pre-filtration of the water purification equipment.

[0003] Since the pretreatment device is used to filter large impurities such as large particles and organic matter, and the impurities filtered by the device are often large in size and large in number, this results in a large volume of the filtered impurities. In addition, the impurity cleaning operation of the existing pretreatment device is to manually open the cover plate and use tools to pick the impurities out of the storage chamber to complete the impurity cleaning operation. This results in a high frequency of manual impurity cleaning, cumbersome operation and a large workload. Based on the above problems, the present invention was conceived. Utility Model Content

[0004] The utility model aims to provide a water inlet pretreatment device for water purification equipment, which can realize convenient cleaning of impurities, thereby reducing the workload and making it more practical.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a water inlet pretreatment device for water purification equipment, comprising a water inlet main pipe, a filter screen arranged in the water inlet main pipe, the water inlet main pipe is provided with a slag discharge port connecting the outside and the water inlet main pipe flow channel, the filter screen is movably arranged in the water inlet main pipe and has a filtering position and a slag discharge position, when the filter screen is in the filtering position, a temporary storage area for temporarily storing impurities is formed between the filter screen and the water inlet main pipe, when the filter screen is in the slag discharge position, a guide part for guiding the impurities in the temporary storage area to be discharged from the slag discharge port is formed on the filter screen, a driving component for driving the filter screen to switch between the filtering position and the slag discharge position is connected to the filter screen, when the filter screen is in the filtering position, a sealing component for sealing the slag discharge port is connected to the filter screen and the sealing component and the filter screen are linked.

[0006] By adopting the above technical solution, the driving component drives the filter to the filtering position. When the filter is in the filtering position, the sealing component seals the slag discharge port through linkage, so as to avoid water leakage; and the impurities in the water body passing through the water inlet main pipe are temporarily stored in the temporary storage area under the filtration of the filter, so as to achieve the filtering purpose. When it is necessary to clean the impurities in the temporary storage area, the driving component drives the sealing component to open the slag discharge port during the process of switching the filter from the filtering position to the slag discharge position, and the impurities in the temporary storage area are discharged from the slag discharge port under the action of the guide part, so as to realize the automatic discharge and cleaning of impurities, making the impurity cleaning operation more convenient, thereby reducing the workload and making it more practical.

[0007] It is further configured as follows: the slag discharge port is arranged around the center of the water inlet main pipe to form a ring shape, and the guide portion is a cone that is convex and gradually shrinks on the side opposite to the slag discharge port and facing away from the water flow direction.

[0008] By adopting the above technical solution, the annular slag discharge port can increase the slag discharge volume, reduce the probability of impurities getting stuck during the slag discharge process, and improve the smoothness of slag discharge; and the conical structure guide part can better guide the impurities to move around and be discharged from the slag discharge port.

[0009] It is further configured as follows: the driving component is arranged on the side of the filter screen facing the water flow direction, the filter screen reciprocates along the axis of the water inlet main pipe and is connected to a guiding component for guiding the movement of the filter screen.

[0010] By adopting the above technical solution, this setting structure can reduce the probability of contact between the driving component and impurities, thereby avoiding the driving component from malfunctioning due to impurities, thereby improving the reliability of the structure; and through the set guide component to guide the filter to move precisely, the reliability and service life of the structure are improved.

[0011] It is further configured as follows: the driving assembly includes a rotating shaft rotatably arranged in the water inlet main pipe, an eccentric wheel rotating with the rotating shaft, a motor arranged outside the water inlet main pipe and used to drive the rotating shaft to rotate, and a linkage rod moving with the filter screen and extending toward the eccentric wheel and abutting against the outer periphery of the eccentric wheel, wherein the linkage rod has a tendency to move toward one side of the eccentric wheel.

[0012] By adopting the above technical solution, the linkage rod with a movement tendency is always against the outer periphery of the eccentric wheel. The position of the linkage rod against the eccentric wheel is changed by driving the eccentric wheel with the motor-driven shaft, thereby changing the height of the filter screen and realizing the switching of the filter screen between two states.

[0013] It is further configured as follows: the guide assembly includes a plurality of slide seats fixedly arranged on the inner wall of the water inlet main pipe and distributed around the center of the water inlet main pipe, and a plurality of slide rods moving with the filter screen and cooperating with the plurality of slide seats, and the plurality of slide rods are arranged in a one-to-one correspondence with the plurality of slide seats.

[0014] By adopting the above technical solution, the slide rod cooperates with the slide seat to guide the movement of the filter screen, thereby improving the structural accuracy to ensure the reliability of the operation of the structure.

[0015] It is further configured as follows: the sealing assembly includes a sealing ring that moves with the filter screen, an upper sealing ring that is arranged on the water inlet main pipe and located on one side of the slag discharge port, and a lower sealing ring that is arranged on the sealing ring and located on the other side of the slag discharge port. When the filter screen is in a filtering state, the sealing ring cooperates with the upper sealing ring and the lower sealing ring to seal the slag discharge port.

[0016] By adopting the above technical solution, the sealing ring, the upper sealing ring and the lower sealing ring cooperate to achieve the sealing of the slag discharge port, avoid leakage and achieve a better sealing effect.

[0017] It is further configured that: one end of the sealing ring facing away from the guiding portion extends out a slag discharge port in a direction opposite to the guiding portion.

[0018] By adopting the above technical solution, this setting structure can prevent impurities from falling into the side of the water inlet main pipe after being filtered by the filter net during the slag discharge process, thereby improving the filtering effect and the practicality of the structure.

[0019] In summary, the utility model has the following beneficial effects: the utility model can realize the convenient cleaning of impurities, thereby reducing the workload and making it more practical. BRIEF DESCRIPTION OF THE DRAWINGS
