Detailed Description

In the conventional system with the filter, the system cannot normally run and needs to be stopped for waiting in the process of cleaning the filter, so that the working efficiency of the system is low. Therefore, the filter is provided, and when the filter is cleaned, a system provided with the filter can work normally without stopping the machine, so that the working efficiency of the system can be improved.

In order to make those skilled in the art better understand the technical solution of the present application, the filter provided in the present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

As shown, the filter includes an inlet conduit 100 and a plurality of filter conduits 200. The sidewall of the inlet pipe 100 is provided with a plurality of through holes 100a. Each of the filter pipes 200 is detachably connected to the inlet pipe 100, and different filter pipes 200 are communicated with the inside of the inlet pipe 100 through different through holes 100a. The filter conduit 200 is provided with a drain opening (not visible in the figure).

In use, water (or other fluid, for convenience of description, water is taken as an example) flows into the water inlet pipe 100, then flows into the filtering pipe 200 through the through hole 100a, and is filtered by the filtering pipe 200 and then is discharged from the water outlet of the filtering pipe 200.

In the figure, two filter pipelines 200 are provided, the two filter pipelines 200 are connected to the same length position of the water inlet pipeline 100, and the two filter pipelines 200 are symmetrically arranged along the center line of the length of the water inlet pipeline 100. Of course, in practical implementation, more than two filter pipelines 200 may be provided, and different filter pipelines 200 may be connected to different length positions of the water inlet pipeline 100.

The filter further includes a switching means 300, the switching means 300 switches different through holes 100a, and when the through hole 100a is opened, the filter pipe 200 communicating with the inlet pipe 100 through the through hole 100a performs a filtering function, and when the through hole 100a is closed, the filter pipe 200 communicating with the inlet pipe 100 through another through hole 100a performs a filtering function, thereby enabling switching of different filter pipes 200.

By arranging the switching device 300 and the plurality of filter pipelines 200, and communicating different filter pipelines 200 with the interior of the water inlet pipeline 100 through different through holes 100a, when the filter is cleaned, only one or more through holes 100a can be closed once to cut off the communication between one or more filter pipelines 200 and the water inlet pipeline 100, then the one or more filter pipelines 200 are detached for cleaning, and the one or more through holes 100a are opened after the cleaning is completed and the filter pipelines are reassembled, and during the period, other filter pipelines 200 are communicated with the water inlet pipeline 100, so that the filter pipeline is in an activated state and plays a filtering function.

Therefore, when the filter provided by the application is cleaned, one or more filter pipelines are always in an enabled state to play a filtering function, so that a system provided with the filter can work normally without shutdown during cleaning, and the working efficiency of the system can be improved. For example, the filter can be arranged in a water-cooling temperature box commonly used in the temperature test, and the water-cooling temperature box does not need to be stopped when the filter is cleaned, so that the continuous temperature test can be ensured, and the temperature test progress can be accelerated.

Specifically, the filtering duct 200 includes a filtering duct body 200a and a filtering core 200b disposed inside the filtering duct body 200 a. The filter conduit body 200a is detachably coupled to the inlet conduit 100 in one end thereof, and forms a water inlet at the end. The length of the filtering pipeline 200 is provided with a slag discharge port 200c and an opening and closing component for opening and closing the slag discharge port 200c towards the other end. When the filter pipeline 200 is disassembled and cleaned, the slag discharge port 200c is opened, so that impurities and cleaning wastewater in the filter element 200b are discharged through the slag discharge port 200c, the filter pipeline 200 is cleaned and then is reloaded in the water inlet pipeline 100, and the slag discharge port 200c is in a closed state when the filter pipeline 200 is normally started. The slag discharge port 200c and the water inlet are respectively arranged at the two ends of the length direction of the filter pipeline 200, so that when the filter is cleaned, water can flow from the water inlet at one end to the slag discharge port 200c at the other end through the filter element 200b, and the filter element 200b can be cleaned completely.

Specifically, in the illustrated embodiment, the opening and closing assembly includes a plug 200d and a gasket 200e, a small diameter portion of the plug 200d is inserted into the slag discharge port 200c, and the gasket 200e is installed between the large diameter portion of the plug 200d and an end surface of the filter pipe 200.

Specifically, in the illustrated embodiment, the lengthwise centerline of each filter conduit 200 is at a predetermined angle with respect to the lengthwise centerline of the inlet conduit 100, such that the single filter conduit 200 forms a "Y" shape in the inlet conduit 100. The arrangement is small in water flow resistance and compact in overall structure.

Specifically, the switching device 300 includes at least one switching component, and each switching component is responsible for switching on and off two through holes 100a. In the illustrated embodiment, the water inlet pipe 100 is provided with two through holes 100a, so that the switching device 300 is provided with only one switching component, but in practical implementation, the number of the switching components can be flexibly adjusted according to the number of the through holes 100a.

Specifically, in the illustrated embodiment, the switching assembly includes a baffle 300a and a driving unit, the baffle 300a is located inside the water inlet pipe 100, the driving unit drives the baffle 300a to reciprocate between the first through hole 100a and the second through hole 100a of the two through holes 100a, when the baffle moves to the first position, the first through hole 100a is closed by the baffle 300a, the second through hole 100a is opened, and when the baffle moves to the second position, the second through hole 100a is closed by the baffle 300a, and the first through hole 100a is opened. In addition, a limiting part 100d can be arranged on the hole wall of the through hole 100a, and when the baffle reaches the first position or the second position, the baffle collides with the limiting part 100d, so that the baffle stops at the first position or the second position.

Of course, the driving unit may also switch the barrier 300a between the first position and the second position by driving the barrier 300a to flip, in comparison, the movement response is quicker and the action is more stable.

Specifically, in the illustrated embodiment, the driving unit extends into the inlet pipe 100 through a through hole 100a and is connected to the baffle 300a, and the driving unit drives the baffle 300a to reciprocate along the radial direction of the inlet pipe 100 to switch the baffle 300a between the first position and the second position, so that each switching assembly is responsible for switching two through holes 100a sequentially arranged along the radial direction of the inlet pipe 100. By the arrangement, the whole structure is simple and compact.

Of course, the driving unit may also switch the baffle 300a between the first position and the second position by driving the baffle 300a to reciprocate along the length of the inlet conduit 100, so that each switching assembly is responsible for switching two through holes 100a arranged in sequence along the length of the inlet conduit 100.

Specifically, in the illustrated embodiment, the driving unit includes a mover 300b and a rotator 300c. The moving member 300b is coupled to the barrier 300a, and the moving member 300b is further coupled to the rotating member 300c by a screw. The moving member 300b and the rotating member 300c may each adopt a rod-shaped structure.

The rotary member 300c is rotatable with respect to the inlet pipe 100, and the rotary member 300c is fixed with respect to the inlet pipe 100 in the moving direction of the moving member 300b, that is, the rotary member 300c is only rotatable with respect to the inlet pipe 100 and is not movable with respect to the inlet pipe 100 in the moving direction of the moving member 300 b.

Since the rotary member 300c cannot move in the moving direction of the mover 300b with respect to the inlet pipe 100, when the rotary member 300c rotates, its rotational motion can be converted into the movement of the mover 300b and the barrier 300a by the screw. The driving unit having such a structure is simple in structure and easy to operate, and the shutter 300a can be switched to open and close the different through holes 100a by rotating the rotary member 300c. In the embodiment, the driving unit is not limited to this configuration, as long as the driving unit can drive the shutter 300a to change between the two through holes 100a.

Specifically, in the illustrated embodiment, the driving unit further includes a handle 300d, one end of the rotary member 300c extends out of the water inlet pipe 100 and the filter pipe 200, and the handle 300d is connected to the end of the rotary member 300c, and may be specifically sleeved on the outer circumference of the end of the rotary member 300c. The rotating member 300c can be rotated by operating the handle 300d to improve the convenience of operation.

Specifically, in the illustrated embodiment, the driving unit further includes an elastic member 300e, one end of the elastic member 300e is connected to the baffle 300a, and the other end is connected to the sidewall of the water inlet pipe 100, and the elastic member 300e applies an elastic force to the baffle 300a to overcome the water flow resistance, that is, the elastic force applied to the baffle 300a during the movement process is opposite to the water flow resistance during the movement process. For example, in the view of fig. 1, when the baffle 300a closes the through hole 100a on the right side, the elastic member 300e is in a compressed state, and when the baffle 300a moves from right to left, the elastic member 300e applies a leftward elastic force to the baffle 300a, so as to assist the baffle 300a to overcome the resistance of the water flow to the right; when the baffle 300a closes the through hole 100a on the left side, the elastic member 300e is in a stretched state, and when the baffle 300a moves from left to right, the elastic member 300e applies a rightward elastic force to the baffle 300a, thereby assisting the baffle 300a to overcome a leftward water flow resistance.

Therefore, by providing the elastic member 300e, the baffle plate 300a can be assisted to overcome the resistance of the water flow, so that when the rotating member 300c is operated to move the baffle plate 300a, the operating force required to be applied is small, and the operation is more labor-saving.

Further, as shown in fig. 1, the filter may further include an extension pipe 400, and a length direction of the extension pipe 400 and a length direction of the water inlet pipe 100 are inserted into each other. And, the outside of the end of the extension pipe 400 is provided with a second tapered surface 400a, the inside of the end of the inlet pipe 100 is provided with a first tapered surface 100b, and the first tapered surface 100b and the second tapered surface 400a contact each other, thereby achieving sealing of the connection position of the extension pipe 400 and the inlet pipe 100. In use, if the length of the inlet conduit 100 is not sufficient, the extension conduit 400 may be connected.

Specifically, in the illustrated embodiment, the first protrusion 100c is disposed on the outer side of the water inlet pipe 100, the second protrusion 400b is disposed on the outer side of the extension pipe 400, the first protrusion 100c and the second protrusion 400b are fastened and connected by the threaded fastener 500, and the first tapered surface 100b and the second tapered surface 400a are in close contact with each other under the fastening force of the threaded fastener 500. The arrangement can improve the connection reliability of the water inlet pipeline 100 and the extension pipeline 400, and facilitates the disassembly and assembly of the extension pipeline 400.

In summary, the core idea of the present application is to use the switching device 300 to switch and activate different filter pipelines 200 by setting the switching device 300 and a plurality of filter pipelines 200, so that when cleaning part of the filter pipelines 200, the rest of the filter pipelines 200 can work normally, so that the filter can still function normally during cleaning, and thus the equipment configured with the filter does not need to be stopped for waiting.

The foregoing has been a description of the principles and implementations of the present application using specific examples, which are provided solely to aid in understanding the methods and their core concepts of the present application. It should be noted that the present application can be carried out with several modifications and alterations without departing from the principle of the present application, and these modifications and alterations also fall into the protection scope of the claims of the present application.
