Description

Technical Field

[0001] The utility model relates to the field of purification and filtration, in particular to a filtration device for purifying mountain spring water. Background Art

[0002] Mountain spring water contains more impurities and needs to be filtered to separate solid impurities. For example, the patent document with the publication number CN220939568U discloses a quartz sand filtration device for mountain spring water, which includes a filtration tank. An outer cover is wrapped around the filtration tank. A water inlet pipe and a filtered water discharge pipe are installed on the filtration tank. The water inlet pipe and the filtered water discharge pipe both penetrate through the filtration tank and the outer cover and are fixedly connected to the filtration tank and the outer cover together. A filter plate is installed inside the filtration tank. The water inlet pipe and the filtered water discharge pipe are respectively located below, above and above the filter plate. The above device can gather and completely discharge the impurities in the filtration tank, so that the inside of the filtration tank can be cleaned, improving the cleaning efficiency and ensuring that the subsequent filtration effect is not affected. In the prior art, when filtering, a filter plate is used to separate large particle impurities from solid and liquid. However, after long-term use, the filter plate may be blocked, resulting in a decrease in filtration efficiency. To avoid this situation, it is required that the filtration device can automatically perform reverse flushing to dredge the filter plate when it is blocked. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a filtration device for purifying mountain spring water to solve the above problems.

[0004] The utility model realizes the above purpose through the following technical solutions:

[0005] A filtration device for purifying mountain spring water includes a device main body. The device main body includes two filter barrels arranged side by side. An impurity separation mechanism is arranged inside the filter barrel. The impurity separation mechanism includes a filter chamber. A water inlet pipe is arranged inside the upper end of the filter chamber. The lower end of the water inlet pipe is in a horn shape. A sliding frame is slidably connected to the lower end of the water inlet pipe. A floating component is fixedly connected to the middle of the sliding frame. A lower plug is fixedly connected to the lower end of the sliding frame. An upper plug is fixedly connected to the upper end inside the sliding frame. The upper plug can form a sealing fit with the lower end of the water inlet pipe. Quartz stone filter plates are filled at the lower end of the filter chamber. A drain pipe is arranged in the middle of the quartz stone filter plates. The top of the drain pipe is in a horn shape. The top of the drain pipe can form a sealing fit with the lower plug. A delay mechanism is arranged at the top of the filter chamber. The delay mechanism is used to delay the reset of the sliding frame.

[0006] Preferably, a top cover is fixedly connected to the top of the filter barrel. The top cover is fixedly connected to the water inlet pipe. The bottom of the top cover is fixedly connected to the top of the filter chamber. A bottom cover is fixedly connected to the bottom of the filter barrel. A plurality of legs are fixedly connected to the bottom of the bottom cover. The middle of the bottom cover is hermetically and fixedly connected to the drain pipe.

[0007] Preferably, a same filtered water discharge pipe is fixedly connected to the front sides of the two filter barrels. Normally open electric valves are installed near both ends of the filtered water discharge pipe close to the filter barrels. A same communicating pipe is fixedly connected to the rear sides of the two filter barrels. A normally closed electric valve is installed on the communicating pipe. The communicating pipe connects the spaces inside the two filter barrels. A same conveying pipe is fixedly connected to the tops of the two water inlet pipes.

[0008] Preferably, the connection position of the filtered water discharge pipe and the filter barrel is higher than the lower end of the filter chamber.

[0009] Preferably, a limiting ring is fixedly connected to the top of the sliding frame. The outer shape of the limiting ring is a ring shape with one protruding part. A ball is rotatably connected to the bottom of the protruding part of the limiting ring.

[0010] Preferably, the delay mechanism includes a fixing plate fixedly connected to the top of the filter chamber. A notched ring is rotatably connected to the middle of the top of the fixing plate. One side of the notch of the notched ring is provided with an inclined surface. A driven gear ring is fixedly connected to the outside of the notched ring. A motor is fixedly connected to the top of the fixing plate. A driving gear is fixedly connected to the output end of the motor. The driving gear meshes with the driven gear ring.

[0012] The beneficial effects are as follows:

[0013] 1. As the clogging degree of the quartz stone filter plate increases, the water level above it continuously rises. The floating assembly also rises accordingly. After reaching a position, the delay mechanism captures and limits the sliding frame. At this time, the water inlet pipe is closed and the drain pipe is opened. The water level in the filter barrel is higher than the water level in the filter chamber. Thus, the quartz stone filter plate is reversely flushed. The sewage generated by the flushing leaves the device through the drain pipe. In this way, the function of automatically reversely flushing the quartz stone filter plate is realized, avoiding clogging, reducing the maintenance frequency, and being convenient for use.

[0014] 2. Through the arrangement of two juxtaposed filter barrels, when reverse flushing is carried out on one side filter barrel, the normally open electric valve on it is closed, and the normally closed electric valve on the communicating pipe is opened. In this way, a part of the purified water generated by the other side filter barrel flows into the filter barrel undergoing reverse flushing, providing a large amount of clean water for its reverse flushing work, increasing the reverse flushing time and enhancing the effect. Moreover, the juxtaposed arrangement ensures that the device will not stop during the reverse flushing operation and can continuously produce purified mountain spring water.

[0029] The present utility model will be further described below with reference to the accompanying drawings:

[0030] As Figures 1-8As shown in the figure, a filtering device for purifying mountain spring water includes a device main body. The device main body includes two filter barrels 101 arranged side by side. An impurity separation mechanism is provided in the filter barrel 101. The impurity separation mechanism includes a filter chamber 203. After the mountain spring water with sediment and solid impurities enters the filter chamber 203, the sediment and solids are separated. The sediment and solids remain inside the filter chamber 203. An inlet pipe 201 is provided inside the upper end of the filter chamber 203. The lower end of the inlet pipe 201 is in a horn shape. A sliding frame 204 is slidably connected to the lower end of the inlet pipe 201. A floating assembly 205 is fixedly connected to the middle of the sliding frame 204. A lower plug 206 is fixedly connected to the lower end of the sliding frame 204. An upper plug 207 is fixedly connected to the upper end inside the sliding frame 204. The upper plug 207 can form a sealing fit with the lower end of the inlet pipe 201. Quartz stone filter plates 208 are filled at the lower end of the filter chamber 203. A drain pipe 202 is provided in the middle of the quartz stone filter plates 208. The top of the drain pipe 202 is in a horn shape. The top of the drain pipe 202 can form a sealing fit with the lower plug 206. A delay mechanism is provided at the top of the filter chamber 203. The delay mechanism is used to delay the reset of the sliding frame 204. A limit ring 209 is fixedly connected to the top of the sliding frame 204. The shape of the limit ring 209 is a ring shape with one protruding part. A ball 210 is rotatably connected to the bottom of the protruding part of the limit ring 209. When the filtering operation lasts for a long time, after a lot of sediment and other impurities accumulate on the surface area of the quartz stone filter plates 208, the filtering performance of the quartz stone filter plates 208 weakens. Then the water accumulated above the quartz stone filter plates 208 gradually increases. At this time, the continuously rising water level drives the floating assembly 205 to rise. The floating assembly 205 drives the sliding frame 204 to rise. The lower plug 206 is disengaged from the drain pipe 202, and the drain pipe 202 is opened. The upper plug 207 forms a fit with the inlet pipe 201, and the inlet pipe 201 is closed. At the same time, the limit ring 209 enters the delay mechanism and triggers the telescopic switch 306. The sliding frame 204 cannot be reset. In this way, due to the discharge of the raw water from the drain pipe 202, the pressure inside the filter chamber 203 decreases, and the purified water inside the filter barrel 101 flows backward. The purified water passes through the quartz stone filter plates 208 to achieve reverse flushing. The impurities flushed out reversely are discharged from the device through the drain pipe 202.

[0031] The top of the filter barrel 101 is bolted to the top cover 102 through a flange. The top cover 102 is fixedly connected to the water inlet pipe 201. The bottom of the top cover 102 is fixedly connected to the top of the filter chamber 203. The bottom of the filter barrel 101 is bolted to the bottom cover 103 through a flange. A number of legs 104 are welded to the bottom of the bottom cover 103. The middle of the bottom cover 103 is hermetically and fixedly connected to the drain pipe 202. The front sides of the two filter barrels 101 are bolted to the same filtered water discharge pipe 105 through a flange. Normally open electric valves 106 are installed near both ends of the filtered water discharge pipe 105 close to the filter barrels 101. The rear sides of the two filter barrels 101 are bolted to the same connecting pipe 107 through a flange. A normally closed electric valve 108 is installed on the connecting pipe 107. The connecting pipe 107 connects the spaces inside the two filter barrels 101. The tops of the two water inlet pipes 201 are bolted to the same conveying pipe 109 through a flange. The connection position of the filtered water discharge pipe 105 and the filter barrel 101 is higher than the lower end of the filter chamber 203. The mountain spring water enters the filter chamber 203 from the conveying pipe 109 through the water inlet pipe 201. The water that has been filtered and separated flows from inside the filter barrel 101 into the filtered water discharge pipe 105, and then enters the ultrafiltration device for fine filtration. When the quartz stone filter plate 208 on one side is backwashed, the normally open electric valve 106 on the same side is closed, and the normally closed electric valve 108 is opened, and part of the filtered water generated on the other side is drawn into the filter barrel 101 to provide sufficient filtered water for the backwashing.

[0032] The delay mechanism includes a fixing plate 301 fixedly connected to the top of the filter chamber 203. In the middle of the top of the fixing plate 301, a notched ring 305 is rotatably connected. One side of the notch of the notched ring 305 is provided with an inclined surface. A driven gear ring 304 is fixedly connected to the outside of the notched ring 305. A motor 302 is fixedly connected to the top of the fixing plate 301. The output end of the motor 302 is fixedly connected with a driving gear 303. The driving gear 303 meshes with the driven gear ring 304. A telescopic switch 306 is installed on one side of the fixing plate 301. The bottom of the telescopic switch 306 can contact the floating component 205. The telescopic switch 306 is electrically connected to the motor 302, the normally open electric valve 106, and the normally closed electric valve 108. The limiting ring 209 passes through the fixing plate 301 and is flush with the notched ring 305. At the same time, the floating component 205 triggers the telescopic switch 306. The motor 302 drives the driving gear 303 to rotate. The driving gear 303 drives the driven gear ring 304 to rotate. The driven gear ring 304 drives the notched ring 305 to rotate. The inclined surface at the notch of the notched ring 305 contacts the ball 210. The notched ring 305 lifts the limiting ring 209. At this time, the upper plug 207 is fully mated with the water inlet pipe 201 to form a seal, and the lower plug 206 is completely separated from the drain pipe 202. The drain pipe 202 is completely opened. After the notched ring 305 rotates one week, the notch on the notched ring 305 corresponds to the protrusion on the limiting ring 209 again. At this time, the sliding frame 204 resets under the action of gravity and the impact of the water flow in the water inlet pipe 201. The telescopic switch 306 closes to generate an electrical signal. The motor 302 receives the electrical signal and starts to rotate. The normally open electric valve 106 receives the electrical signal and closes. The normally closed electric valve 108 receives the electrical signal and opens.

[0033] Working principle: The mountain spring water with sediment and solids enters the filter chamber 203 through the water inlet pipe 201 from the conveying pipe 109. Subsequently, the water filtered by the quartz stone filter plate 208 enters the filter barrel 101. The sediment and solids are separated and deposited on the top of the quartz stone filter plate 208. The filtered water accumulates continuously, so the filtered water can flow from the filter barrel 101 into the filtered water discharge pipe 105, and then enters the ultrafiltration device for fine filtration. When the filtering work lasts for a long time, after a large amount of impurities such as sediment accumulate on the surface of the quartz stone filter plate 208, the filtering performance of the quartz stone filter plate 208 weakens. Then, the water accumulated above the quartz stone filter plate 208 gradually increases. At this time, the continuously rising water level drives the floating assembly 205 to rise. The floating assembly 205 drives the sliding frame 204 to rise. The lower plug 206 is disengaged from the drain pipe 202, and the drain pipe 202 opens. The upper plug 207 forms a fit with the water inlet pipe 201, and the water inlet pipe 201 is closed. At the same time, the limit ring 209 enters the delay mechanism and triggers the telescopic switch 306. The telescopic switch 306 closes to generate an electrical signal, and the motor 302 starts to rotate when it receives the electrical signal. After the limit ring 209 passes through the fixing plate 301, it is flush with the notch ring 305. At the same time, the floating assembly 205 triggers the telescopic switch 306. The motor 302 drives the driving gear 303 to rotate. The driving gear 303 drives the driven gear ring 304 to rotate. The driven gear ring 304 drives the notch ring 305 to rotate. The inclined surface at the notch of the notch ring 305 contacts the ball 210, and the notch ring 305 lifts the limit ring 209. At this time, the upper plug 207 is fully engaged with the water inlet pipe 201 to form a seal, and the lower plug 206 is completely separated from the drain pipe 202, and the drain pipe 202 is completely opened. Thus, due to the discharge of the raw water from the drain pipe 202, the pressure in the filter chamber 203 decreases, and the filtered water in the filter barrel 101 flows backward. The filtered water passes through the quartz stone filter plate 208 for reverse flushing. The sediment and solids flushed out reversely are discharged from the device through the drain pipe 202. The normally open electric valve 106 receives the electrical signal and closes, and the normally closed electric valve 108 receives the electrical signal and opens. When one side of the quartz stone filter plate 208 is subjected to reverse flushing, the normally open electric valve 106 on the same side as it closes, and the normally closed electric valve 108 opens to draw part of the filtered water generated on the other side into the filter barrel 101 to provide sufficient filtered water for reverse flushing. After the notch ring 305 rotates one week, the notch on the notch ring 305 corresponds to the protrusion on the limit ring 209 again. At this time, the sliding frame 204 resets under the action of gravity and the impact of the water flow in the water inlet pipe 201. Thus, the reverse flushing work ends.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only to illustrate the principle of the present utility model.
