Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a pre-cleaning skid-mounted filter backflushing and pressurizing device for a pre-filled syringe. Background Technology

[0002] Filters, as key equipment, are widely used in processes such as solid-liquid separation and impurity interception of fluid media. Their core component is the filter element, which purifies the media through physical retention or adsorption. Traditional filters typically consist of a housing, filter element, inlet and outlet pipelines, and a control system. During operation, impurities gradually accumulate on the surface of the filter element, leading to decreased filtration efficiency, increased pressure differential, and in severe cases, system shutdown or equipment damage. Therefore, regular cleaning of the filter element is essential to ensure the long-term stable operation of the filter. Currently, the mainstream technologies for filter element cleaning include backwashing, chemical cleaning, and mechanical cleaning. Among these, backwashing technology is the most widely used due to its ease of operation and low cost. Its principle is to use reverse-flowing fluid to flush the pores of the filter element, removing surface and internal blockages.

[0003] For example, patent CN 218248853 U discloses a dual-filter backwashing pipeline device. The first filter and the second filter are horizontally and longitudinally fixed on both sides of the top center of the support base. The support base is located at the bottom of the first filter and the second filter. The upper part of the center of the inner side of the first filter is connected to the first liquid guide pipe in the same horizontal direction. The center of the lower part of the back plate of the first filter is connected to the first circulation pipe. The lower part of the inner side of the second filter is connected to the second liquid guide pipe in the same horizontal direction.

[0004] The aforementioned backwashing pipeline device has significant defects: the cleaning process requires machine shutdown and disassembly; the filter needs to be removed from the working pipeline, which leads to production interruption and long downtime, affecting work efficiency; and frequent disassembly and assembly can easily cause mechanical damage to the filter element and shorten its service life. Utility Model Content

[0005] This invention proposes a pre-cleaning skid-mounted filter backflushing and pressurizing device for pre-filled syringes, which solves the problem that the filter element cleaning process in the prior art requires machine shutdown and disassembly, affecting work efficiency.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A pre-cleaning skid-mounted filter backflushing booster device for pre-filled syringes includes a skid frame, a filter tank and a booster pump mounted on the skid frame, and a filtration passage that sequentially passes through the filter tank and the booster pump, and a backflushing passage that sequentially passes through the booster pump and the filter tank. The backflushing booster device simultaneously performs filtration and backflushing functions, allowing for both normal filtration and cleaning of the filter element within the filter tank. Furthermore, cleaning the filter element does not require disassembling the filter tank, making backflushing convenient and improving work efficiency.

[0008] The backwashing passage includes a backwash drain pipe, a backwash pipe, and a backwash inlet pipe. The backwash inlet pipe is connected to the inlet of the booster pump, the inlet end of the backwash pipe is connected to the outlet of the booster pump, the outlet end of the backwash pipe is connected to the filter tank, and the backwash drain pipe is connected to the filter tank. When cleaning the filter element in the filter tank, purified water is introduced into the booster pump through the backwash inlet pipe. After being pressurized by the booster pump, the water is introduced into the filter tank for high-pressure rinsing of the filter element, ensuring the rinsing pressure of the purified water during filter element cleaning and improving cleaning efficiency.

[0009] The backwash drain pipe is connected to the lower part of the filter tank and to the outside of the filter element inside the filter tank. During filter element cleaning, purified water flows from the inside of the filter element to the outside of the filter element to rinse it. After rinsing the filter element, the purified water is discharged from the backwash drain pipe.

[0010] The backwash pipe is connected to the bottom of the filter tank and to the interior of the filter element inside the filter tank. The backwash pipe introduces purified water into the filter element, and the flow direction of the purified water during rinsing is opposite to the flow direction of the water during filtration.

[0011] The filtration path includes a filter inlet pipe, a filter pipe, and a filter outlet pipe. The filter inlet pipe is connected to the filter tank, the inlet end of the filter pipe is connected to the filter tank, the outlet end of the filter pipe is connected to the inlet of the booster pump, and the filter outlet pipe is connected to the outlet of the booster pump.

[0012] The filter inlet pipe is connected to the upper part of the filter tank and to the outside of the filter element inside the filter tank. When the backwash pressurization device performs filtration, the water to be filtered enters the filter tank through the filter inlet pipe, and then enters the inside of the filter element from the outside, thus achieving the filtration function.

[0013] The filter tube is connected to the bottom of the filter tank and to the inside of the filter element within the filter tank. Water filtered by the filter element is discharged through the filter tube.

[0014] Valves are installed on the backwash drain pipe, backwash pipe, backwash inlet pipe, filter inlet pipe, filter pipe, and filter outlet pipe. The valves can control the opening and closing of each pipe, thereby enabling the switching between filtration and backwashing functions and improving the functionality of the backwash booster device.

[0015] The filter tank is equipped with a pressure detection device to monitor the internal pressure. During backwashing, the pressure inside the filter tank is monitored to ensure that the backwash water thoroughly rinses the filter element, while also guaranteeing safe operation.

[0016] The skid-mounted frame is equipped with rollers at its bottom. The rollers provide support for the skid-mounted frame and facilitate its movement, which is beneficial for the transfer of the backflush pressurization device.

[0017] The beneficial effects of this utility model are: 1. The backwash booster device has both filtration and backwashing functions. It can perform normal filtration and cleaning of the filter element in the filter tank. Furthermore, the filter tank does not need to be disassembled when cleaning the filter element. The backwashing operation is convenient and improves work efficiency.

[0018] 2. The backwashing passage has a simple structure, and the device can be modified by adding pipes to the filtration passage, thereby reducing the cost of the backwashing booster device.

[0019] 3. During backwashing, the filter can be pressurized and flushed by closing the backwash drain pipe and continuously introducing backwash water into the filter can, which effectively ensures the cleaning effect of the filter element. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1, such as Figure 1 As shown, a pre-cleaning skid-mounted filter backflushing pressurization device for pre-filled syringes includes a skid frame 5, on which a filter tank 1 and a pressurization pump 2 are mounted. The skid frame 5 is provided with a filter passage that passes through the filter tank 1 and the pressurization pump 2 in sequence, and a backflushing passage that passes through the pressurization pump 2 and the filter tank 1 in sequence. The backwash booster device has both filtration and backwashing functions. It can perform normal filtration and clean the filter element inside the filter tank. When filtration is required, the filtration passage is open, and the filtered water is discharged to the booster pump 2 after passing through the filter pipe 1. The booster pump 2 pressurizes the water before discharge, ensuring efficient discharge and improving filtration efficiency. When the filter tank 1 becomes clogged due to long-term use, the filter element inside the filter tank 1 is backwashed. At this time, the filtration passage is closed, and the backwash passage is open. The backwash water enters the booster pump 2, is pressurized, and then flows into the filter tank 1 to backwash the filter element, thus cleaning the filter tank 1. Furthermore, the filter tank does not need to be disassembled during filter element cleaning, making the backwashing operation convenient and improving work efficiency.

[0027] Furthermore, such as Figure 3 As shown, the backwashing passage includes a backwash drain pipe 12, a backwash pipe 4, and a backwash inlet pipe 3. The backwash inlet pipe 3 is connected to the inlet of the booster pump 2, the inlet end of the backwash pipe 4 is connected to the outlet of the booster pump 2, the outlet end of the backwash pipe 4 is connected to the filter tank 1, and the backwash drain pipe 12 is connected to the filter tank 1. When cleaning the filter element in the filter tank 1, purified water is introduced into the booster pump 2 through the backwash inlet pipe 3. After being pressurized by the booster pump 2, the water is introduced into the filter tank 1 to perform high-pressure rinsing of the filter element, ensuring the rinsing pressure of the purified water during filter element cleaning and improving cleaning efficiency.

[0028] Furthermore, the backwash drain pipe 12 is connected to the lower part of the filter tank 1, and also to the outside of the filter element inside the filter tank 1. During filter element cleaning, purified water flows from the inside of the filter element to the outside, rinsing the filter element. After rinsing, the purified water is discharged from the backwash drain pipe 12. The backwash pipe 4 is connected to the bottom of the filter tank 1, and also to the inside of the filter element inside the filter tank 1. The backwash pipe 4 introduces purified water into the filter element, and the flow direction of the purified water during rinsing is opposite to the flow direction of the water during filtration.

[0029] Furthermore, valves are provided on the backwash drain pipe 12, backwash pipe 4, and backwash inlet pipe 3. A pressure detection device is provided on the filter tank 1 to detect the internal pressure. The valves control the opening and closing of the backwash drain pipe 12, backwash pipe 4, and backwash inlet pipe 3, thus enabling the backwash passage to be open. In this embodiment, the pressure detection device is a pressure gauge. During the backwashing process, the valves on the backwash pipe 4 and backwash inlet pipe 3 are first opened, and the valve on the backwash drain pipe 12 is closed. At this time, the booster pump 2 introduces pressurized backwash water into the filter tank 1. When the pressure gauge detects that the pressure inside the filter tank 1 has increased to the set value, the valve on the backwash drain pipe 12 is opened to discharge the backwash water from the filter tank 1, completing the backwashing cleaning process of the filter element.

[0030] Example 2, based on Example 1, provides a pre-cleaning skid-mounted filter backflush pressurization device for a pre-filled syringe, such as... Figure 2 As shown, the filtration path includes a filter inlet pipe 11, a filter pipe 22, and a filter outlet pipe 21. The filter inlet pipe 11 is connected to the filter tank 1, the inlet end of the filter pipe 22 is connected to the filter tank 1, the outlet end of the filter pipe 22 is connected to the inlet of the booster pump 2, and the filter outlet pipe 21 is connected to the outlet of the booster pump 2. During the filtration process of the backwash booster device, the water to be filtered enters the filter tank 1 through the filter inlet pipe 11. After being filtered by the filter tank 1, the filtered water is fed into the booster pump 2 through the filter pipe 22. After being pressurized by the booster pump 2, the filtered water is discharged from the filter outlet pipe 21. The booster pump 2 can accelerate the discharge efficiency of the filtered water, thereby improving the filtration efficiency of the filter tank 1.

[0031] Furthermore, the filter inlet pipe 11 is connected to the upper part of the filter tank 1, and also to the outside of the filter element inside the filter tank 1. When the backwash pressurization device performs filtration, the water to be filtered enters the filter tank 1 through the filter inlet pipe 11, and then enters the inside of the filter element from the outside, thus achieving the filtration function. The filter pipe 22 is connected to the bottom of the filter tank 1, and also to the inside of the filter element inside the filter tank 1. The water filtered by the filter element is discharged from the filter pipe 22.

[0032] Furthermore, valves are installed on the filter inlet pipe 11, filter pipe 22, and filter outlet pipe 21. The valves can control the opening and closing of the filter inlet pipe 11, filter pipe 22, and filter outlet pipe 21. During filtration, the filter inlet pipe 11, filter pipe 22, and filter outlet pipe 21 are open; during filter cartridge backwashing, the filter inlet pipe 11, filter pipe 22, and filter outlet pipe 21 are closed.

[0033] Furthermore, the skid-mounted frame 5 is equipped with rollers at its bottom. The rollers provide support for the skid-mounted frame 5 and facilitate its movement, which is beneficial for the transfer of the backflush booster device.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
