Description

Technical Field

[0001] This application relates to the field of aquaculture equipment technology, specifically a purification device for aquaculture. Background Technology

[0002] When aquaculture is carried out, the aquaculture water needs to be replaced. When discharging the aquaculture water, because there are a lot of pollutants in the aquaculture water, purification equipment needs to be used to purify the aquaculture water before it can be discharged.

[0003] Chinese utility model patent CN220723854U discloses an aquaculture wastewater purification device. It purifies aquaculture water through a filter layer structure, uses a metered dosing mechanism for precise drug administration, and employs activated carbon, quartz sand, and anthracite in the filter layer structure for filtration. The filter layer is stabilized by an anti-scattering structure. However, with prolonged use, one or more of the activated carbon, quartz sand, or anthracite may fail, resulting in ineffective filtration and requiring replacement. However, the filter plates are fixedly connected to the tank, and the filter layers are sequentially connected via the anti-scattering structure. This means that replacing a failed filter layer requires removing the layers above it one by one, making replacement inconvenient and affecting the purification device's effectiveness.

[0004] Therefore, this application provides a purification device for aquaculture to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a purification device for aquaculture, which aims to solve the problems mentioned in the background art, such as the inconvenience of replacing filter layers when one or more filter materials fail in the existing aquaculture purification equipment due to the stable connection between filter layers via a venting structure.

[0006] To achieve the above objectives, this application provides the following technical solution: a purification device for aquaculture, comprising a tank, a tank cover fixedly installed at the top of the tank, an inlet pipe fixedly installed at the top of the tank cover for inputting aquaculture water, and an outlet pipe fixedly installed at the bottom of the tank for discharging purified aquaculture water.

[0007] To facilitate the replacement of expired purification media: the tank is internally equipped with purification media for wastewater purification, and a filter assembly is installed inside the tank to hold the purification media. The filter assembly includes a cylinder for loading the purification media, a cylinder cover fixedly installed at the top of the cylinder for sealing the cylinder, a partition plate fixedly installed inside the cylinder for separating different types of purification media, and a switch door installed on the outer wall of the cylinder for controlling the opening and closing of the cylinder. Aquaculture water enters the tank through the inlet pipe, is purified by the purification media inside the filter assembly, and is then discharged through the outlet pipe. When some of the purification media becomes expired after long-term use, the cylinder can be lifted out of the tank using the lifting bracket. Then, by opening the switch door corresponding to the expired purification media, the expired purification media inside the cylinder can be removed and replaced, making the replacement of the purification media quick and convenient.

[0008] Preferably, to facilitate support of the filter assembly, a support block for supporting the cylinder is fixedly connected to the inner wall of the tank. The horizontal cross-section of the support block is annular. By placing the cylinder on top of the support block, the cylinder is supported, thereby maintaining the stability of the filter assembly inside the tank.

[0009] Preferably, to facilitate the flow of aquaculture water: the outer wall of the partition plate is fixedly connected to the inner wall of the cylinder, and permeable holes for the flow of aquaculture water are provided at the bottom of the cylinder, the top of the partition plate, and the top of the cylinder cover. By providing the permeable holes at the top of the cylinder cover, aquaculture water can enter the interior of the cylinder. Through the permeable holes at the top of the partition plate, the aquaculture water flows sequentially through different purification materials. The permeable holes at the bottom of the cylinder facilitate the discharge of the purified aquaculture water from the cylinder.

[0010] Preferably, to facilitate the removal of the filter assembly from the tank: a lifting seat for lifting the cylinder cover is fixedly connected to the top of the cylinder cover, and reinforcing ribs for increasing the strength of the cylinder cover are fixedly connected to the outer wall of the lifting seat. When the purified material needs to be replaced, the cylinder cover and the cylinder body can be removed from the tank by hooking the lifting seat with a hook, so that the purified material can be replaced.

[0011] Preferably, to facilitate the replacement of the purified material: the outer wall of the cylinder has an outlet for the purified material to enter and exit; one side of the outlet has an arc-shaped slot for installing the switch door; the end of the switch door away from the arc-shaped slot has a connector for fixing the switch door; the side of the arc-shaped slot near the connector has a connecting groove; and the side of the connecting groove away from the purified material has a locking hole. When some types of purified material fail, the corresponding purified material can be replaced by opening the switch door at the corresponding location, making replacement more convenient.

[0012] Preferably, to facilitate opening and closing the door: the connector includes a plug fixedly installed at one end of the door for interlocking with the connecting groove, and a locking block disposed on one side of the plug for interlocking inside the lock hole. The plug has a cavity inside, and the inner wall of the cavity has an insertion hole. The locking block is interlocked with the insertion hole. A baffle is fixedly connected to one end of the locking block, and an elastic block is disposed on the side of the baffle away from the locking block. By rotating the door, the plug is inserted into the connecting groove, and the locking block, pushed by the elastic block, is inserted into the lock hole, thus closing the door to the discharge port. When the purified material needs to be replaced, pressing the locking block rotates the door to replace the purified material.

[0013] Preferably, to prevent collision between the cylinder and the can: the inner wall of the can is provided with rollers to prevent collision between the cylinder and the can. When the cylinder is placed inside the can, the outer wall of the cylinder will contact the rollers, thereby preventing collision between the cylinder and the can and protecting both the cylinder and the can.

[0014] This application utilizes a design incorporating filter components, purification materials, support blocks, and rollers. Multiple purification materials are layered using a partition plate. When some of the purification materials fail, pressing the locking block moves the door to replace the corresponding material. This eliminates the need to remove all the top layer of the failed material, making material replacement more convenient. Furthermore, the rollers prevent collisions between the cylinder and the tank and guide the vertical movement of the cylinder. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] This embodiment provides a purification device for aquaculture, such as... Figure 1-7 As shown, the purification device includes a tank 1, a tank cover 2 fixedly installed on the top of the tank 1, an inlet pipe 3 fixedly installed on the top of the tank cover 2 for inputting aquaculture water, and an outlet pipe 4 fixedly installed on the bottom of the tank 1 for discharging purified aquaculture water.

[0026] To facilitate the replacement of expired purification material 6: The tank 1 contains purification material 6 for wastewater purification, and a filter assembly 5 for holding the purification material 6. The filter assembly 5 includes a cylinder 51 for loading the purification material 6, a cylinder cover 52 fixedly installed at the top of the cylinder 51 for sealing the cylinder 51, a partition plate 53 fixedly installed inside the cylinder 51 for separating different types of purification material 6, and a switch door 54 installed on the outer wall of the cylinder 51 for controlling the opening and closing of the cylinder 51. When aquaculture water enters the tank 1 through the inlet pipe 3, is purified by the purification material 6 inside the filter assembly 5, and is then discharged through the outlet pipe 4, if some of the purification material 6 becomes expired after long-term use, the cylinder 51 can be lifted out of the tank 1 using the lifting base 56. Then, by opening the switch door 54 corresponding to the expired purification material 6, the expired purification material 6 inside the cylinder 51 can be removed and replaced, making the replacement of the purification material 6 quick and convenient.

[0027] Furthermore, the diameter of the cylinder cover 52 corresponds to the diameter of the cylinder body 51. The cylinder cover 52 is fixedly installed to the cylinder body 51 by bolts, and the tank body 1 and the tank cover 2 are fixedly installed by bolts. A backwash water pipe is installed inside the tank body 1 directly below the bottom of the cylinder body 51. Multiple nozzles are installed on the backwash water pipe facing the outside of the cylinder body 51. Water is sprayed through the multiple nozzles to backwash and clean the inside of the tank body 1. The clean water is discharged from the cleaning pipe installed at the top of the cylinder body 51. An automatic dosing device is installed on one side of the tank body 1. An internal metering pump is installed. When dosing is required, the metering pump is started to draw out the liquid medicine inside the storage tank and transport it to the inside of the tank body 1 through the liquid medicine guide pipe to mix with the sewage, so as to achieve quantitative dosing.

[0028] Specifically, to facilitate the support of the filter assembly 5, a support block 7 for supporting the cylinder 51 is fixedly connected to the inner wall of the tank 1. The horizontal cross-section of the support block 7 is annular. By placing the cylinder 51 on top of the support block 7, the cylinder 51 is supported, thereby maintaining the stability of the filter assembly 5 inside the tank 1. The part of the support block 7 that contacts the tank 1 is welded and fixed. The size of the support block 7 does not obstruct the area where the water permeable hole 58 is opened at the bottom of the cylinder 51, thus providing stable support for the cylinder 51.

[0029] Specifically, to facilitate the flow of aquaculture water: the outer wall of the partition plate 53 is fixedly connected to the inner wall of the cylinder 51, and permeable holes 58 for the flow of aquaculture water are provided at the bottom of the cylinder 51, the top of the partition plate 53, and the top of the cylinder cover 52. By providing permeable holes 58 at the top of the cylinder cover 52, aquaculture water can enter the interior of the cylinder 51. By providing permeable holes 58 at the top of the partition plate 53, the aquaculture water can flow sequentially through different purification materials 6. By providing permeable holes 58 at the bottom of the cylinder 51, the purified aquaculture water can be discharged from the cylinder 51. The partition plate 53 is welded to the contact part of the cylinder 51. The number of partition plates 53 is set according to the type of purification material 6. The total number of partition plates 53 is one less than the number of types of purification material 6. Multiple partition plates 53 are arranged vertically at equal intervals inside the cylinder 51, thereby separating each type of purification material 6. The aquaculture water flowing in from the liquid inlet pipe 3 passes through multiple purification materials 6 in sequence to achieve purification of the aquaculture water. The multiple purification materials 6 inside the cylinder 51 can be one or a combination of activated carbon, quartz sand and anthracite.

[0030] Specifically, to facilitate the removal of the filter assembly 5 from the tank 1, a lifting seat 56 for lifting the cover 52 is fixedly connected to the top of the cover 52. Reinforcing ribs 57 for increasing the strength of the cover 52 are fixedly connected to the outer wall of the lifting seat 56. When the purified material 6 needs to be replaced, the cover 52 and the tank 51 can be removed from the tank 1 by hooking the lifting seat 56 with a hook, allowing for the replacement of the purified material 6. Multiple reinforcing ribs 57 are provided, evenly spaced in a ring. The reinforcing ribs 57 are welded to the cover 52 and the lifting seat 56 to enhance the strength of the lifting seat 56 and the cover 52.

[0031] Specifically, to facilitate the replacement of the purification material 6: the outer wall of the cylinder 51 has an outlet for the purification material 6 to enter and exit. An arc-shaped slot for installing the switch door 54 is provided on one side of the outlet. A connector 55 for fixing the switch door 54 is provided at the end of the switch door 54 away from the arc-shaped slot. A connecting groove is provided on the side of the arc-shaped slot near the connector 55, and a locking hole is provided on the side of the connecting groove away from the purification material 6. When some types of purification material 6 fail, the corresponding purification material 6 can be replaced by opening the corresponding switch door 54, making replacement more convenient.

[0032] More specifically, to facilitate the opening and closing of the switch door 54: the connector 55 includes a plug 551 fixedly installed at one end of the switch door 54 for interlocking with a connecting groove, and a locking block 552 disposed on one side of the plug 551 for interlocking inside a lock hole. The plug 551 has a cavity inside, and the inner wall of the cavity has an insertion hole. The locking block 552 is interlocked with the insertion hole. A baffle 553 is fixedly connected to one end of the locking block 552, and an elastic block 554 is disposed on the side of the baffle 553 away from the locking block 552. By rotating the switch door 54, the plug 551 is inserted into the connecting groove, and the locking block 552 is inserted into the lock hole under the pushing action of the elastic block 554, thus completing the closure of the outlet of the switch door 54. When the purified material 6 needs to be replaced, the switch door 54 can be rotated by pressing the locking block 552 to replace the purified material 6. The dimensions of the connecting slot are adapted to the plug 551. The length of the arc-shaped slot is 0.9 times the length of the switch door 54. The dimensions of the arc-shaped slot are adapted to the dimensions of the switch door 54. The lock hole and the plug hole are the same size. The dimensions of the baffle 553 are 1.2 times the size of the plug hole. The elastic block 554 is an elastic rubber block. Both the baffle 553 and the elastic block 554 are inside the cavity. The elastic block 554 is always in a compressed state. The horizontal cross section of the locking block 552 is a right triangle, and its inclined surface faces away from the switch door 54.

[0033] Specifically, to prevent the cylinder 51 from colliding with the tank 1, the inner wall of the tank 1 is equipped with rollers 8 to prevent collisions between the cylinder 51 and the tank 1. When the cylinder 51 is placed inside the tank 1, the outer wall of the cylinder 51 will contact the rollers 8, thereby preventing collisions between the cylinder 51 and the tank 1 and protecting both the tank 1 and the cylinder 51. Multiple rollers 8 are provided, arranged vertically at equal intervals as a group, or in three groups arranged in a ring at equal intervals. The inner wall of the tank 1 has grooves, the number of which corresponds to the number of rollers 8. A round rod is fixedly welded to the inner wall of each groove, and rollers 8 are fitted onto the outer wall of the round rod. Thus, when the cylinder 51 is placed into the tank 1, the rolling action of the rollers 8 reduces friction during movement of the cylinder 51 and prevents direct collisions between the cylinder 51 and the tank 1.
