Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of an impurity filtering device according to an embodiment of the present invention; FIG. 2 is a cross-sectional view at A-A of FIG. 1; fig. 3 is a top view of fig. 1.
The utility model provides an impurity filtering device, including the jar body 1 that is equipped with filter chamber 2, the inlet tube 3 of being connected with the top of filter chamber 2 and the outlet pipe 4 of being connected with the bottom of the jar body 1.
The filter chamber 2 sets up in jar body 1 and has the trend that extends along the direction of height of jar body 1 to make the liquid of treating that gets into from inlet tube 3 can follow jar body 1's top downstream, and the liquid after filter chamber 2 then gets into the space between jar body 1 and the cavity wall of filter chamber 2, and finally flows out naturally along outlet pipe 4. The liquid filtered by the filter cavity 2 flows out from the water outlet pipe 4 after entering between the tank body 1 and the cavity wall of the filter cavity 2, and the liquid can be deposited at the bottom of the tank body 1 in the process of flowing into the water outlet pipe 4 from the bottom of the tank body 1, so that the cleaning degree of the filtered liquid is further improved.
The impurity filtering device can be connected with other filtered devices and can circulate and repeatedly filter the liquid to be filtered in the filtered devices, and particularly for the filtered devices which are constantly in a working state, the impurity filtering device does not need to be closed, so that the operation is simplified, and the working efficiency is improved.
The following provides a further description of the impurity filtering device provided by the present invention with reference to the accompanying drawings and embodiments.
In view of the fact that the impurity filtering apparatus provided by the present application is more suitable for large flow rate working occasions, in order to improve the filtering efficiency and quality, please refer to fig. 2 and 3, the filtering chamber 2 may include a front chamber 21 disposed at the top of the tank 1 and a plurality of filtering cartridges 22 disposed along the height direction of the tank 1; the top end of any filter cartridge 22 is attached to the bottom surface of the front chamber 21.
The liquid to be filtered enters the front cavity 21 from the water injection port 31 of the water inlet pipe 3 and disperses from the bottom surface of the front cavity 21 into the respective filter cartridges 22, and since the total cavity wall of the plurality of filter cartridges 22 has a larger surface area than the single filter cavity 2 having a larger diameter, it is possible to simultaneously filter a larger amount of the liquid to be filtered to ensure a sufficient supply of the liquid in the filtered device.
Obviously, compared with a single filter cavity 2 with a larger diameter, the filter cartridges 22 with a smaller diameter can reduce the influence of the damage of the cavity wall of the filter cartridge 22 on the overall filtering effect, and the liquid to be filtered is conveniently monitored and maintained.
Since the impurity filtering apparatus is mostly applied to a growth line for uninterrupted operation, many impurities are collected in the filter cartridge 22 after long-term use, part of the impurities are deposited on the bottom of the filter cartridge 22, and part of the impurities block the filter holes 221.
In response to the foregoing problem, the filter cartridge 22 may further include a metal cylinder fixedly connected to the bottom surface of the partition 211, i.e., the front chamber 21, and a filter bag detachably fitted in the metal cylinder. The filter bag is sleeved in the metal cylinder, impurities carried by liquid to be filtered cannot pass through the filter bag and are gathered in the filter bag, namely, only the filter bag in the metal cylinder is replaced when the filter cylinder 22 is cleaned, so that the workload and the time for cleaning the filter cylinder 22 are reduced, and the influence on a production line is further reduced.
Referring to fig. 1, 2 and 3, in addition to the above embodiment, in order to facilitate the replacement of the filter bag in the metal cylinder, the impurity filtering device of the present invention further includes a sealing cover 5 detachably connected to the top of the cylinder 1. The sealing cover 5 is in a hemispherical structure, and when the sealing cover 5 is fixed on the top of the can body 1, the sealing cover 5 and the can body 1 form a hemispherical front cavity 21. After the impurity filtering device is used for a period of time, the sealing cover 5 can be detached to open the front cavity 21, so that the bottom surface of the front cavity 21, that is, the partition 211, is exposed, and the filter bag is taken out from the partition 211 and the metal cylinder connected with the partition 211.
The shape of the sealing lid 5 is not limited to a hemispherical structure, and any other arcuate structure capable of sealing with the can body 1 may be used as the sealing lid 5. Of course, the radius of curvature of the dome is not likely to be too small to avoid that the volume of the front chamber 21 is too small to accommodate the liquid to be filtered flowing in from the inlet pipe 3.
In order to ensure the joint strength and the sealing effect of the sealing cover 5 and the tank body 1, the utility model provides an impurity filtering device is still including setting up in the sealing cover 5, being used for locking the locking mechanism 6 of the sealing cover 5 and the tank body 1 when the sealing cover 5 covers and detains in the top of the tank body 1. The first end of the locking mechanism 6 is fixed on the sealing cover 5, and the second end is used for hooking or clamping the tank body wall, for example, the locking mechanism 6 with a screw structure is inserted into a threaded hole of the tank body wall, in the process, the locking mechanism 6 applies a larger extrusion force to the contact surface of the sealing cover 5 and the tank body 1, and the lower end surface of the sealing cover 5 is ensured to be tightly attached to the upper end surface of the tank body 1.
On the basis of the above embodiment, the water inlet pipe 3 can radially extend into the tank body 1 from the bottom of the tank body 1, and further upwardly extend to the center of the bottom surface of the front cavity 21, that is, the center of the partition 211, along the height direction of the tank body 1. The liquid to be filtered in the water inlet pipe 3 is gushed out upwards from the through hole in the center of the partition board 211 and is diffused to the periphery of the partition board 211, so that the liquid enters the filter cartridge 22 at a stable flow rate, and the phenomenon that the water pressure of the liquid to be filtered flowing out from the water inlet pipe 3 is too high to cause impact damage to the filter cartridge 22 is avoided; it also enables the liquid to be filtered to flow through the entire chamber wall of the filter cartridge 22, increasing the filtration area of a single filter cartridge 22 and the usage of the entire filter cartridge 22.
Further, a pressure gauge 8 for measuring the pressure of the liquid to be filtered in the filter cartridge 22 may be further provided in the filter cartridge 22. Since the flow rate and the solution composition of the liquid to be measured entering each filter cartridge 22 from the front chamber 21 are substantially the same, that is, the pressure value at the same time in each filter cartridge 22 is almost the same, the pressure gauge 8 may be provided in only one of the filter cartridges 22 to monitor the pressure in the filter cartridge 22.
Considering that the pressure of the liquid to be filtered in the front chamber 21 is close to the pressure of the liquid to be filtered of each filter cartridge 22, the pressure gauge 8 may also be used to measure the pressure of the liquid to be filtered in the front chamber 21 as a parameter for detecting the use state of the filter cartridge 22.
When the filter cartridge 22 is clogged with a part of the filter holes 221 due to a large amount of impurities inside, the flow rate of the liquid to be filtered flowing from the front chamber 21 is larger than the flow rate of the liquid flowing from the filter cartridge 22 into the tank 1, so that the pressure inside the filter cartridge 22 is significantly increased, in other words, when the pressure gauge 8 detects that the pressure inside the filter cartridge 22 is increased, the filter cartridge 22 is clogged seriously, and it is necessary to clean or replace the filter cartridge 22.
Correspondingly, because the filtered liquid can be further deposited at the bottom of the tank body 1, a sewage discharge pipe 7 can be arranged at the bottom of the tank body 1 so as to open the sewage discharge pipe 7 periodically to discharge impurities at the bottom of the tank body 1 or discharge sewage after the tank body 1 is cleaned.
The position of the blow-off pipe 7 is preferably arranged at the lowest point of the tank body 1 so as to ensure that the liquid in the tank body 1 can be fully drained. For example, a base 9 for erecting the tank 1 may be arranged at the bottom of the tank 1, so that the bottom of the tank 1 is suspended, and the sewage discharge pipe 7 includes a first water discharge pipe vertically connected to the bottom of the tank 1 and a second water discharge pipe vertically connected to the first water discharge pipe and horizontally arranged with respect to the ground.
When the impurity filtering device is connected with a device to be filtered which needs uninterrupted work, in order to provide power for the liquid to be filtered to circularly reciprocate between the impurity filtering device and the device to be filtered, the impurity filtering device also comprises a water pump which is connected with the water inlet pipe 3 and is used for pumping the liquid to be filtered into the front cavity 21.
The liquid to be filtered which flows out from the water outlet of the filtered device is pumped into the water inlet pipe 3 by the water pump, then flows upwards to the front cavity 21 of the tank body 1 along the water inlet pipe 3, and flows downwards to each filter cylinder 22 from the front cavity 21; the liquid flowing out through the filter cavity 2 is collected at the bottom of the tank body 1 and flows into the water inlet of the filtered device from the water outlet pipe 4 at the bottom of the tank body 1.
The utility model also provides a production line before coating treatment, which comprises a plurality of process water tanks with water inlets and water outlets and at least one impurity filtering device connected with any process water tank; specifically, the water inlet pipe 3 of the impurity filtering device may be connected to a water outlet of any one of the process water tanks of the pretreatment line, and the water outlet pipe 4 may be connected to a water inlet of the same process water tank of the pretreatment line. The impurity filtering device can filter the tank liquor in the coating pretreatment production line, namely the liquor to be filtered, all the time when the coating pretreatment production line works, so that the service life of the tank liquor is prolonged, and the product quality is improved.
Except that before the application processing production line, the utility model provides an impurity filtering device can also be applied to other production lines, and its application mode is similar with aforementioned before-mentioned before-application processing production line, can refer to aforementioned connection, using-way and use, and no longer the description here.
