Description

Technical Field

[0001] The utility model belongs to the technical field of filtering equipment, and in particular relates to a raw water direct-taking filtering device. Background Art

[0002] Raw water generally refers to water collected from nature, including groundwater, spring water, reservoir water and other natural water sources in nature. It has not undergone any artificial purification treatment and is taken from natural water bodies or reservoirs, such as rivers, lakes, ponds or underground aquifers, and is used as a water supply source; or it refers to water flowing into the first treatment unit of a water treatment plant. The water in the reservoir used by the water plant to regulate the water pressure of the water supply network is not raw water. The quality of raw water varies depending on the water source.

[0003] However, during the initial filtration of raw water, larger solids are stored in the filter. As the filtration progresses, the filter gradually becomes saturated and the filter needs to be stopped for cleaning. This results in low efficiency and causes problems during use. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a raw water direct extraction filtering device.

[0005] The present application proposes a raw water direct filtration device, including a placement cylinder, wherein the rear portion of the top end of the placement cylinder is connected to a water inlet pipe, the rear portion of the bottom end of the placement cylinder is connected to a discharge pipe, a rotatable filter cylinder is arranged in the placement cylinder, a plurality of removable small cylinders are arranged in the filter cylinder, and a window is opened at the front end of the placement cylinder.

[0006] Specifically, the top end of the small cylinder is open, and a filter screen is arranged at the bottom end of the small cylinder.

[0007] Specifically, two arc grooves are provided on the outer wall of the front end of the small cylinder, and the two arc grooves are symmetrically distributed with the center of the circle formed. A slot is provided on the inner wall of one side of the two arc grooves. A U-shaped rod is arranged in front of the small cylinder, and insertion rods are respectively arranged at the opposite ends of the two longitudinal rods of the U-shaped rod, and the insertion rods can be inserted into the slots.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] Taking two small cylinders as an example, the raw water enters the placement cylinder through the water inlet pipe, and then falls into one of the small cylinders in the filter cylinder. After being filtered by the small cylinder, the raw water enters the discharge pipe, and the larger solids remain in the small cylinder. Then the filter cylinder rotates, and the unused small cylinder is rotated to the bottom of the water inlet pipe at the rear. At this time, the small cylinder containing solid impurities rotates to the front, and then the small cylinder is taken out from the window for cleaning. After cleaning, the small cylinder is put into the filter cylinder again. By reciprocating the above steps, the solid impurities after filtration can be cleaned to avoid impurity accumulation, and the cleaning operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] A raw water direct filtration device, such as Figure 1-3 As shown, it includes a placing cylinder 1, the rear portion of the top end of the placing cylinder 1 is connected to a water inlet pipe, the rear portion of the bottom end of the placing cylinder 1 is connected to a discharge pipe, a rotatable filter cylinder 2 is arranged in the placing cylinder 1, a plurality of removable small cylinders 3 are arranged in the filter cylinder 2, and a window is opened at the front end of the placing cylinder 1. The top of the filter cartridge 2 is open, and several through holes are provided at the bottom of the filter cartridge 2. The number of through holes is the same as the number of small cylinders 3. Several small cylinders 3 are evenly distributed around the center of the filter cartridge 2. Two small cylinders 3 are used as an example for explanation. Raw water enters the placement cartridge 1 through the water inlet pipe, and then falls into one of the small cylinders 3 in the filter cartridge 2. Raw water enters the discharge pipe through the filtration of the small cylinder 3, and larger solids remain in the small cylinder 3. Then the filter cartridge 2 is rotated, and the unused small cylinder 3 is rotated to the bottom of the water inlet pipe at the rear. At this time, the small cylinder 3 containing solid impurities is rotated to the front, and then the small cylinder is taken out from the window for cleaning. After cleaning, the small cylinder 3 is loaded into the filter cartridge 2 again. By reciprocating the above steps, the solid impurities after filtration can be cleaned to avoid impurity accumulation, and the cleaning operation is simple.

[0014] Specifically, the top of the small cylinder 3 described in this embodiment is open, and a filter screen is arranged at the bottom of the small cylinder 3. The raw water in the water inlet pipe directly enters the small cylinder 3 through the top opening of the small cylinder 3, and then the solids are filtered through the filter screen at the bottom.

[0015] Furthermore, the front end outer wall of the small cylinder 3 described in this embodiment is provided with two arc grooves 4, and the two arc grooves 4 are symmetrically distributed with the center of the circle formed, and a slot 5 is provided on one side inner wall of the two arc grooves 4, and a U-shaped rod 6 is arranged in front of the small cylinder 3, and two longitudinal rods of the U-shaped rod 6 are respectively provided with insertion rods 7 at the opposite ends, and the insertion rod 7 can be inserted into the slot. When the small cylinder 3 needs to be taken out, the two longitudinal rods of the U-shaped rod 6 are respectively inserted into the arc groove 4, and then rotated 90 degrees, and the insertion rod 7 enters the slot 5. At this time, the U-shaped rod 6 is pulled to drive the small cylinder to move outward, and the small cylinder 3 is taken out, and the operation is simple and fast.
