Description

Technical Field

[0001] This utility model belongs to the field of sugar-free tissue culture technology, and specifically relates to a submerged plate filter. Background Technology

[0002] Currently, in plant tissue culture or sugar-free culture involving forced ventilation (pressurized ventilation), it is necessary to make holes in the culture container to pressurize the filtered gas into the culture container and replace the original gas in the container. Since remote filtration cannot avoid pipeline contamination, a filter needs to be installed at the air inlet of the culture container.

[0003] According to patent application CN215388345U, published on January 4, 2022, an air filter perforator is disclosed, comprising: a top cover and a base movably connected thereto. The top cover includes: a connector portion serving as an air inlet, a main body portion connected to the base, and an air filter membrane disposed within the main body portion. The base includes: a knob portion and a grille disposed on its top. This device has a simple structure and is easy to install, and can filter the flowing gas; the perforator base has a grille, which allows the flowing gas to disperse and flow out.

[0004] Existing perforated plate filters create a large single-point protrusion on the top of the culture container after installation, making it impossible to stack the containers during handling. In addition, the gas introduced is blown directly onto the tissue culture seedlings, which can easily cause mechanical damage to the tender plants. To solve the above problems, we provide a submerged perforated plate filter. Utility Model Content

[0005] The purpose of this invention is to provide a submerged plate filter to solve the problems mentioned in the background art, which are that the existing plate filters, after installation, form a large single-point protrusion structure on the top of the culture container, making it impossible to stack the containers during transportation. At the same time, the gas introduced is blown directly onto the tissue culture seedlings, which can easily cause mechanical damage to the tender plants.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a submerged plate filter, comprising a box body, a box cover fitted onto the top of the box body, a top cover fitted onto the top of the box cover, a groove integrally machined on the top of the top cover, a connector integrally machined inside the groove, a base provided at the bottom of the top cover, an annular groove integrally machined inside the base, several through holes opened inside the base, a first microporous filter membrane placed inside the base, the bottom of the top cover threadedly connected to the base, a diffuser plate provided at the bottom of the base, and several claws integrally machined on the surface of the diffuser plate.

[0007] Preferably, the inner side of the claw is provided with a slot, and the surface of the base is integrally machined with a protrusion that matches the slot, and the claw engages with the protrusion through the slot.

[0008] Preferably, the number of through holes is six, the number of claws is six, and the surface of the base is integrally machined with six limiting blocks.

[0009] Preferably, a large washer is fitted onto the surface of the top cover, a small washer is abutted against the bottom of the top cover, and an annular groove adapted to the small washer is formed at the bottom of the top cover.

[0010] Preferably, the surface of the box cover is fitted with a vent plate, the surface of the vent plate is fitted with a sealing gasket, a second microporous filter membrane is placed inside the vent plate, and a fixing ring is fixedly fitted to one end of the vent plate.

[0011] This utility model has the following beneficial effects: The device, through the matching design of the recessed groove and the connector, enables the lid to be stacked stably, improving the convenience of transportation and storage. After the gas flows through the first microporous filter membrane for efficient filtration, it is guided by the gap of the diffuser plate claws, so that the airflow changes from vertical downward to horizontal diffusion, and is evenly blown to the top of the lid. This not only avoids the damage that may be caused by direct blowing on the plants, but also effectively removes the condensation at the top, maintains the light transmittance, and thus significantly improves the light energy utilization efficiency.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Example 1: refer to Figure 1-3A submerged plate filter includes a housing 1, a housing cover 2 fitted onto the top of the housing 1, a top cover 3 fitted onto the top of the housing cover 2, a groove 4 integrally machined on the top of the top cover 3, a connector 5 integrally machined inside the groove 4, a base 6 provided at the bottom of the top cover 3, an annular groove integrally machined inside the base 6, several through holes 8 opened inside the base 6, a first microporous filter membrane 7 placed inside the base 6, the bottom of the top cover 3 threadedly connected to the base 6, a diffuser plate 9 provided at the bottom of the base 6, several claws 10 integrally machined on the surface of the diffuser plate 9, which can cooperate with the first microporous filter membrane 7 to increase the gas filtration flow rate by setting the annular groove.

[0016] Specifically, the device, through the matching design of the recessed groove 4 and the connector 5, enables the lid 2 to be stacked stably, improving the convenience of transportation and storage. After the gas flows through the first microporous filter membrane 7 for efficient filtration, it is guided by the gap of the diffuser plate 9 and the claw 10, so that the airflow changes from vertical downward to horizontal diffusion, and is evenly blown to the top of the lid 2. This not only avoids the damage that may be caused by direct blowing on the plants, but also effectively removes the condensation at the top, maintains the light transmittance, and thus significantly improves the light energy utilization efficiency.

[0017] refer to Figure 2 The inner side of the claw 10 is provided with a slot 11, and the surface of the base 6 is integrally machined with a protrusion 12 that matches the slot 11. The claw 10 is engaged with the protrusion 12 through the slot 11, which can effectively facilitate the installation of the diffuser plate 9 and the base 6.

[0018] refer to Figure 2 There are six through holes 8 and six claws 10. The surface of the base 6 is integrally machined with six limiting blocks 13. The limiting blocks 13 are aligned with the circular array direction of the through holes 8. After installation, the through holes 8 and the claws 10 are designed to be misaligned, which facilitates the smooth blowing of gas.

[0019] refer to Figure 2 A large washer 14 is fitted onto the surface of the top cover 3. By setting the large washer 14, the sealing performance at the connection between the top cover 3 and the box cover 2 can be improved.

A second microporous filter membrane 18 is placed inside the exhaust vent plate 17, and a fixing ring 16 is fixedly fitted onto one end of the exhaust vent plate 17. By setting the exhaust vent plate 17, exhaust gas can be effectively discharged. The second microporous filter membrane 18 can ensure gas exchange inside and outside the device while blocking the intrusion of external microorganisms and preventing pollution.

[0021] Brief description of usage: By setting the groove 4, the connector 5 is placed inside the groove 4. This recessed design ensures that the box cover 2 can be stacked. The air tube is inserted into the connector 5, so that the incoming gas is filtered through the first microporous filter membrane 7 and then discharged through the through hole 8. By setting the diffuser plate 9, the gas is blown out from between the multiple claws 10, so that the incoming gas is changed from vertical downward to horizontal blowing towards the top inside the box cover 2. This can avoid the possibility of directly blowing the plant and killing it, and can also blow away the condensation at the top inside the box cover 2, thus avoiding a decrease in light energy utilization.
