Description

Technical Field

[0001] This utility model belongs to the field of drip irrigation filter technology, specifically relating to a drip irrigation filter with a multi-stage series filter chamber and a bypass sewage discharge channel. Background Technology

[0002] As is well known, drip irrigation filters are one of the many agricultural devices and a key component to ensure the normal operation of irrigation systems. The core task of drip irrigation filters is to remove impurities from irrigation water that may clog drip tape (pipes) and drippers, ensuring smooth water flow and uniform irrigation.

[0003] A utility model patent with patent authorization announcement number CN220877904U discloses a drip irrigation filter, including a tube body, a cap, and a locking assembly. The tube body has an installation opening that extends along the length of the tube body. The cap is rotatably connected to the installation opening. The cap contains multiple filter plates, and the filter holes on the multiple filter plates decrease in size sequentially from the first end of the tube body to the second end of the tube body. When the cap blocks the installation opening, the circumferential walls of the multiple filter plates abut against the inner wall of the tube body. The locking assembly is used to lock the cap and prevent the cap from moving away from the installation opening.

[0004] However, existing drip irrigation filters also have certain drawbacks. Most existing drip irrigation filters use a single-stage filter cartridge for water filtration and rely on manual operation to clean the impurities inside the cartridge. This not only results in poor filtration effect but also makes them inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to provide a drip irrigation filter with a multi-stage series filtration chamber and a bypass sewage discharge channel. This solves the problem that existing drip irrigation filters mostly use a single-stage filter cartridge for water filtration and rely on manual operation to clean the impurities inside the cartridge, which not only results in poor filtration effect but also inconvenience in use.

[0006] To achieve the above objectives, this utility model provides a drip irrigation filter with a multi-stage series filtration chamber and a bypass drainage channel, including a base frame. Two symmetrically distributed filter cylinders are arranged on the upper part of the base frame. Each filter cylinder has three supporting legs arranged in a circular array fixedly connected to its lower end. Each supporting leg is fixedly connected to the base frame. An inlet pipe is fixedly connected to the upper end of the right filter cylinder, and a large-diameter inlet is fixedly connected to the upper end of the inlet pipe. A pre-filtration mechanism is arranged inside the large-diameter inlet. A connecting pipe is fixedly connected between the two filter cylinders, and a delivery pump is arranged outside the connecting pipe. An outlet pipe is fixedly connected to the lower end of the left filter cylinder. Each filter cylinder has a filter inside, and a bypass drainage mechanism is provided on both the base frame and the filter cylinders. The bypass sewage discharge mechanism includes a sewage discharge pipe. The sewage discharge pipe is fixedly connected to the back of the filter cylinder and is located on the upper side of the filter. A sealing ring is fixedly connected to the inner wall of the filter cylinder. A rotating pipe is rotatably connected to the inner wall of the sealing ring. A support frame is fixedly connected to the front of the base frame. The support frame contacts the rotating pipe. A gear one is fixedly sleeved on the outer side of the rotating pipe. A motor is fixedly installed on the front of the support frame. A gear two is fixedly sleeved on the outer side of the output shaft of the motor. The gear two meshes with the gear one. A flushing pipe is installed on the inner wall of the rotating pipe through a sealed bearing. Through the action of the flushing pipe, the rotating pipe, and other structures, the filter can be backwashed. Under the action of the motor, gear one, and other structures, the spray nozzle can rotate back and forth over a wide range to ensure a good backwashing effect. Multiple evenly distributed nozzles are fixedly connected to the upper side of the rotating tube. The nozzles are located below the filter, and the water can be sprayed through the nozzles.

[0007] The principle of this utility model is as follows: by setting a large-diameter liquid inlet, water can be input for use. Under the action of the filter screen, large particles and other impurities in the water can be filtered out, thus performing pre-filtration of impurities. The handle can be pulled upward to move the mounting ring along the surface of the guide rod to ensure the stable movement of the mounting ring, thereby moving the filter screen upward. When the mounting ring contacts the baffle, the filter screen can be fully exposed through the large-diameter liquid inlet, allowing for comprehensive cleaning of impurities accumulated on the filter screen. Water can be introduced into the rotating pipe and spray pipe through the flushing pipe to backwash the filter. When the motor drives the output shaft to rotate, it can drive the second gear to rotate. In the meshing relationship, the second gear can drive the first gear to rotate, so that the limit plate rotates along the surface of the support frame to ensure the rotation stability of the rotating pipe. This, in turn, drives the spray pipe to rotate back and forth over a wide range, performing efficient backwashing of the filter. In conjunction with the function of the drain pipe, the impurities backwashed can be discharged by side flow.

[0008] The beneficial effects of this utility model are as follows: This solution, through the setting of two filter cylinders, a bypass sewage discharge mechanism, and other components, can ensure multi-stage series filtration and bypass sewage discharge operation of the drip irrigation filter. Under the action of the flushing pipe, gear, motor, and other structures, the spray pipe can be deflected back and forth over a wide range to perform efficient backwashing of the filter, ensuring good backwashing and sewage discharge effects. Through the setting of a large-diameter liquid inlet, water can be input. Under the action of the filter screen, large particulate impurities can be pre-filtered, improving the subsequent filtration effect of the water. Under the action of the handle, mounting ring, guide rod, and other structures, the filter screen can be pulled to expose the large-diameter liquid inlet, facilitating comprehensive cleaning and use by subsequent operators.

[0009] Furthermore, the pre-filtration mechanism includes support ears. Two symmetrically distributed support ears are fixedly connected to the inner wall of the large-diameter inlet. A guide rod is fixedly connected to the upper end of each support ear. A baffle is fixedly sleeved on the outer side of each guide rod. An installation ring is slidably sleeved on the outer side of the guide rod. A filter screen is fixedly connected to the inner wall of the installation ring. A handle is fixedly connected to the upper end of the installation ring. Through the setting of the filter screen, large particulate impurities in the water can be pre-filtered. The handle, guide rod, and other structures allow the filter screen to be exposed in the large-diameter inlet, facilitating thorough cleaning and use by operators.

[0010] Furthermore, the mounting ring contacts the support ear, and the mounting ring is slidably connected to the large-diameter liquid inlet. The mounting ring can be used to fix and support the filter screen.

[0011] Furthermore, multiple rubber rings are fixedly sleeved on the outside of the handle, and the multiple rubber rings are evenly distributed on the handle. The setting of the rubber rings makes it easy to pull the handle to move it.

[0012] Furthermore, two evenly distributed limiting discs are fixedly sleeved on the outer side of the rotating tube. Each limiting disc is rotatably connected to the support frame. The rotation of the rotating tube can be limited by the setting of the limiting discs. Attached Figure Description

An outlet pipe 9 is fixedly connected to the lower end of the left filter cylinder 2. A filter 10 is arranged inside each filter cylinder 2.

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a pre-filtration mechanism 6 is installed inside the large-diameter inlet 5. The pre-filtration mechanism 6 includes support ears 61. Two symmetrically distributed support ears 61 are fixedly connected to the inner wall of the large-diameter inlet 5. A guide rod 62 is fixedly connected to the upper end of each support ear 61. A baffle 63 is fixedly sleeved on the outer side of each guide rod 62. An installation ring 64 is slidably sleeved on the outer side of the guide rod 62. A filter screen 65 is fixedly connected to the inner wall of the installation ring 64. A handle 66 is fixedly connected to the upper end of the installation ring 64. Through the setting of the filter screen 65, large particulate impurities in the water can be pre-filtered. With the action of the handle 66, guide rod 62 and other structures, the filter screen 65 can be exposed in the large-diameter inlet 5, which is convenient for operators to clean and use.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, the mounting ring 64 contacts the support ear 61 and is slidably connected to the large-diameter liquid inlet 5. The mounting ring 64 can fix and support the filter screen 65. Multiple rubber rings 67 are fixedly sleeved on the outside of the handle 66. The multiple rubber rings 67 are evenly distributed on the handle 66. The setting of the rubber rings 67 makes it easy to pull the handle 66 to move.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a bypass drainage mechanism 11 is jointly provided on the base frame 1 and the filter cartridge 2. The bypass drainage mechanism 11 includes a drain pipe 110. The drain pipe 110 is fixedly connected to the back of the filter cartridge 2 and is located on the upper side of the filter 10. A sealing ring 111 is fixedly connected to the inner wall of the filter cartridge 2. A rotating pipe 112 is rotatably connected to the inner wall of the sealing ring 111. A support frame 114 is fixedly connected to the front of the base frame 1. The support frame 114 contacts the rotating pipe 112. A gear 116 is fixedly sleeved on the outer side of the rotating pipe 112. A motor 117 is fixedly installed on the front of the support frame 114. A gear 118 is fixedly sleeved on the outside of the output shaft of the motor 117. The gear 118 meshes with the gear 116. A flushing pipe 119 is installed on the inner wall of the rotating pipe 112 through a sealed bearing. Through the action of the flushing pipe 119, the rotating pipe 112 and other structures, the filter 10 can be backwashed. Under the action of the motor 117, the gear 116 and other structures, the spray pipe 113 can rotate back and forth over a wide range to ensure a good backwashing effect.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, multiple evenly distributed nozzles 113 are fixedly connected to the upper side of the rotating pipe 112. The nozzles 113 are located below the filter 10. Water can be sprayed by the nozzles 113. Two evenly distributed limiting discs 115 are fixedly sleeved on the outer side of the rotating pipe 112. Each limiting disc 115 is rotatably connected to the support frame 114. The rotation of the rotating pipe 112 can be limited by the limiting discs 115.

[0020] The specific implementation process of this utility model is as follows: Water can be input and used through the large-diameter liquid inlet 5. Under the action of the filter screen 65, large particles and impurities in the water can be filtered out, and the impurities can be pre-filtered. The handle 66 can be pulled upward to drive the mounting ring 64 to slide along the surface of the guide rod 62 to ensure the stable movement of the mounting ring 64, thereby driving the filter screen 65 to move upward. When the mounting ring 64 contacts the baffle 63, the filter screen 65 can be fully exposed through the large-diameter liquid inlet 5, and the impurities accumulated on the filter screen 65 can be thoroughly cleaned. Through the flushing pipe 119, water can be introduced into the rotating pipe 112 and the spray pipe 113 to backwash the filter 10. When the motor 117 drives the output shaft to rotate, it can drive the gear 118 to rotate. In the meshing relationship, the gear 118 can drive the gear 116 to rotate, so that the limit plate 115 rotates along the surface of the support frame 114 to ensure the rotation stability of the rotating pipe 112. This, in turn, drives the spray pipe 113 to rotate back and forth over a wide range, performing efficient backwashing on the filter 10. In conjunction with the function of the drain pipe 110, the backwashed impurities are discharged by side flow.

[0021] This solution, through the arrangement of two filter cartridges 2 and a bypass drainage mechanism 11, ensures multi-stage series filtration and bypass drainage of the drip irrigation filter. The flushing pipe 119, gear 116, and motor 117 enable the spray pipe 113 to deflect over a wide range, performing efficient backwashing of the filter 10 to ensure good backwashing and drainage effects. The large-diameter inlet 5 allows water to be introduced, and the filter screen 65 performs pre-filtration of large particles, improving the subsequent filtration effect. The handle 66, mounting ring 64, and guide rod 62 allow the filter screen 65 to be pulled to expose the large-diameter inlet 5, facilitating thorough cleaning and use by subsequent operators.
