Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water purification equipment, in particular to a filter element skeleton of a stack filter and the stack filter. Background Art
[0002] The stack filter is a relatively common filtering device. The stack filter screen is formed by overlapping a large number of relatively thin texture sheets with very fine surfaces, and is locked into a cylindrical filter element by an end cover and a filter element skeleton. Large holes are opened on the basic side surface of the filter element skeleton to allow water to flow through, so as to realize the filtering or backwashing channel. During filtering, the stack sheets are locked by the filter element skeleton and the end cover through springs and mechanical structures, and water flows in from the outside to the inside. The stack sheets intercept particulate impurities such as floating objects, rust, and sediment in the water. During backwashing, the stack sheets are loosened, and water flows out from the inside to the outside to wash the particulate impurities such as floating objects, rust, and sediment attached to the stack sheets. However, large holes are opened on the side surface of the filter element skeleton, and the water flow out from the inside to the outside is relatively dispersed, and a high-pressure water flow cannot be formed to impact the particulate impurities on the stack sheets. Over time, the gap between the stack sheets becomes larger, so that the filtering accuracy cannot reach the expected effect, affecting the service life of the filter and bringing a bad experience to consumers. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the above technical problems, and provide a filter element skeleton of a stack filter and the stack filter. By changing the structure of the filter element skeleton, the utility model forms a large-flux flow channel during filtering and forms small holes with high-pressure backwashing of the stack sheets during backwashing, so as to improve the backwashing effect.
[0004] The technical solution adopted by the utility model to solve the above technical problems is: a filter element skeleton of a stack filter, including a valve core and a skeleton sleeved outside the valve core. A valve core pipe is provided on the valve core, a valve core pipe wall is provided on the valve core pipe, and a valve core water passing hole is opened on the valve core pipe wall. A filtering through-flow channel and a backwashing spray water channel are provided on the skeleton. The valve core can rotate to open the filtering through-flow channel with the valve core water passing hole or open the backwashing spray water channel with the valve core water passing hole and close the filtering through-flow channel with the valve core pipe wall. By rotating, the filtering through-flow channel is opened during filtering. At this time, the backwashing spray water channel can be opened or closed, so that the water flow can be filtered with a large flux during filtering; during sewage discharge, the backwashing spray water channel is opened, and at this time, the filtering through-flow channel is closed, so that only a small channel flushes the stack sheets from the inside to the outside during sewage discharge.
[0005] Preferably, a boss is provided on the valve core pipe, and upper and lower slideways surrounding the skeleton are provided on the skeleton. The boss is arranged in the upper and lower slideways to rotate the valve core in the skeleton along the upper and lower slideways.
[0006] Preferably, the upper and lower slides include a first upper and lower slide and a second upper and lower slide. The first upper and lower slide and the second upper and lower slide together form a circumferentially surrounding framework. The first upper and lower slide is provided with a first high point and a first low point, and the second upper and lower slide is provided with a second high point and a second low point. The first high point is arranged above the second low point, and the second high point is arranged above the first low point.
[0007] Preferably, the convex platforms include a first convex platform and a second convex platform. The first convex platform is arranged within the first upper and lower slide, and the second convex platform is arranged within the second upper and lower slide. In the filtering state, the first convex platform is located at the first low point, and the second convex platform is located at the second low point. At this time, the framework presses the stack of sheets tightly from above; in the sewage discharge state, the first convex platform rotates to the first high point, and the second convex platform rotates to the second high point, causing the framework to move downward and the stack of sheets to loosen, so that the impurities existing in the gaps between the stack of sheets in the sewage discharge state can be cleaned thoroughly.
[0008] Preferably, the filtering water flow channel includes a number of filtering water holes arranged on the framework, and the backwashing spray water flow channel includes a number of backwashing spray holes arranged on the framework. The backwashing spray holes are arranged on one side of the filtering water holes.
[0009] Preferably, the filtering water holes are communicated with the backwashing spray holes, and the filtering water holes and the backwashing spray holes form a convex-shaped hole. The filtering water holes are large holes, and the backwashing spray holes are small holes. The small holes and the large holes form a convex-shaped hole.
[0010] Preferably, an end cap is provided at the top of the framework, and a convex ring is provided on the framework. The stack of sheets is arranged between the convex ring and the end cap.
[0011] Preferably, a limiting groove for restricting the rotation of the framework is provided on the framework. Through the design of the limiting groove, the framework is clamped in the filter bottle, making the framework unable to rotate, so as to control the opening or closing of the filtering water flow channel and the backwashing spray water flow channel by rotating the valve core.
[0012] Preferably, a valve core seat is provided on the valve core. The valve core seat is provided with a water inlet and a water outlet. The water outlet is communicated with the valve core pipe, and the valve core can rotate to switch the water outlet into a backwashing water inlet. In the filtering state, the water inlet is communicated with the water inlet pipe, and the water outlet is communicated with the water outlet pipe. Water flows in from the water inlet, enters the flow channel between the filter bottle and the stack of sheets upward, passes through the stack of sheets for filtration, then enters the valve core through the filtering water flow channel and the valve core water holes, and then flows out from the water outlet; rotate the valve core, the water inlet pipe is communicated with the water outlet, and the water outlet becomes the backwashing water inlet. Water flows in from the water outlet, passes through the valve core upward through the valve core water holes and the backwashing spray holes to wash the stack of sheets.
[0013] A stack filter includes the filter element framework, and stacks of sheets are arranged outside the framework.
[0014] The beneficial effects of the present utility model are as follows: By changing the structure of the filter element skeleton, the present utility model forms a large-throughput flow channel during filtration and small holes with high-pressure backwashing laminated sheets during backwashing, thereby improving the backwashing effect.
