Description

Technical Field

[0001] This utility model belongs to the field of wastewater purification technology, and in particular relates to an electroplating wastewater filtration device. Background Technology

[0002] The production process of electroplated cables includes electroplating. When treating the wastewater generated by electroplating, chemical agents can be added to the wastewater to form insoluble precipitates of heavy metal ions. The precipitates are then filtered out by a filtration device.

[0003] The filter screens of existing filtration devices are usually fixed in the wastewater tank. When cleaning, they need to be removed from the tank. This process is not only time-consuming and labor-intensive, but also often requires at least two people to work together. Sometimes, it also requires the help of professional hoisting equipment. For situations where the filter screens need to be cleaned frequently, this cleaning method is obviously inefficient.

[0004] Therefore, it is necessary to improve the filtration devices in the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide an electroplating wastewater filtration device that improves the convenience of cleaning the filter screen.

[0006] To achieve the above objectives, the specific technical solution of the electroplating wastewater filtration device of this utility model is as follows:

[0007] An electroplating wastewater filtration device includes a wastewater tank with an inlet pipe and an outlet pipe respectively at both ends. The top of the wastewater tank is open. A filter screen is connected inside the wastewater tank through a connector. The filter screen is vertically inserted into the connector. A lifting power component is provided on the side of the wastewater tank. The lifting end of the lifting power component is rotatably connected to the filter screen.

[0008] Preferably, in order to improve the ease of filter installation and the ease of installation inside the wastewater tank, the connector includes slots, which are vertically distributed on the inner walls of both sides of the wastewater tank. The top of the slots communicates with the outside, and the two sides of the filter are respectively inserted into the two slots.

[0009] Preferably, in order to improve the filtration effect of the filter screen, a sealing ring is provided around the four edges of the filter screen, and the filter screen is sealed to the inner wall of the wastewater tank through the sealing ring.

[0010] Preferably, in order to ensure that the equipment can operate normally when the filter screen is cleaned and to improve the operating efficiency of the equipment, at least two filters are provided, and each filter screen is arranged at intervals along the direction from the water inlet pipe to the water outlet pipe, and each filter screen is independently driven to lift by a lifting power component.

[0011] Preferably, in order to drive the filter screen to rise and fall, and at the same time realize the rotation of the filter screen in the horizontal plane, the lifting power component is a hydraulic cylinder, and the lifting end of the hydraulic cylinder is connected to the filter screen through a bearing.

[0012] Preferably, to facilitate cleaning of the filter, the filter includes a flexible outer frame in the shape of a rectangle, and two support members are provided on the inner side of the outer frame. The two support members are distributed along the two diagonals of the outer frame, and the ends of the support members are fixedly connected to the corners of the outer frame.

[0013] Preferably, in order to ensure the supporting effect on the outer frame, the support component includes a threaded sleeve and two threaded rods. One end of each of the two threaded rods is fixedly connected to two corners of the outer frame, and the other end of each of the two threaded rods is threadedly engaged with the threaded sleeve. The thread directions of the two threaded rods are opposite.

[0014] Preferably, in order to improve the ease of cleaning the filter, a plurality of first mesh lines and a plurality of second mesh lines are distributed on the inner side of the outer frame.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0023] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the filter device and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] like Figure 1 As shown, an electroplating wastewater filtration device includes a wastewater tank 1 with an inlet pipe 102 and an outlet pipe 101 respectively at both ends. The top of the wastewater tank 1 is open. A filter screen 3 is connected inside the wastewater tank 1 through a connector. The filter screen 3 is inserted and fitted vertically into the connector. A lifting power component 2 is provided on the side of the wastewater tank 1. The lifting end of the lifting power component 2 is rotatably connected to the filter screen 3.

[0025] Wastewater generated after electroplating cables is typically treated by adding chemical agents to cause heavy metal ions in the wastewater to form insoluble precipitates. These precipitates are then filtered out by a filtration device, thus treating the wastewater and ensuring it meets discharge standards. In operation, wastewater enters wastewater tank 1 through inlet pipe 102 and passes through filter screen 3 to remove precipitates. The filtered wastewater is then discharged through outlet pipe 101. After a period of filtration, a large amount of precipitates accumulate on filter screen 3, affecting its filtration efficiency. At this point, a lifting mechanism 2 raises filter screen 3 from the wastewater tank 1 to above it, and then the filter screen is manually pushed around the lifting mechanism. The lowering component 2 rotates to one side of the wastewater tank 1, and then the lifting component 2 lowers the filter screen 3. At this time, the filter screen 3 is located on the outside of the wastewater tank 1, which facilitates cleaning of the filter screen 3. By lifting and rotating the filter screen 3, the position of the filter screen 3 inside and outside the wastewater tank 1 is switched, which greatly improves the convenience of cleaning the filter screen 3 and improves the working efficiency of the filtration device. After cleaning, the filter screen 3 is raised and rotated to the top of the wastewater tank 1, and then the filter screen 3 is lowered into the wastewater tank 1 so that the filter screen 3 can be inserted and matched with the plug. The plug is used to position and fix the filter screen 3, which improves the stability of the filter screen 3 installed inside the wastewater tank 1, so as to ensure the stable and reliable filtration effect of the filtration device.

[0026] Further improvements include, for example Figure 2 As shown, the connector includes slots 103, which are vertically distributed on the inner walls of both sides of the wastewater tank 1. The top of the slots 103 is connected to the outside, and the two sides of the filter screen 3 are respectively inserted into the two slots 103.

[0027] Specifically, after the slot 103 is inserted into the two sides of the filter screen 3, it can fix the sides of the filter screen 3. At the same time, during the process of lifting and placing the filter screen 3, the filter screen 3 can move along the slot 103 to guide the filter screen 3, thereby improving the firmness of the filter screen 3 installed inside the wastewater tank 1 and the convenience of placing and placing the filter screen 3.

[0028] Further improvements include, for example Figure 3 As shown, a sealing ring is provided around the four edges of the filter screen 3, and the filter screen 3 is sealed to the inner wall of the wastewater tank 1 through the sealing ring.

[0029] Specifically, the sealing ring allows the edge of the filter screen 3 to be sealed to the inner wall of the wastewater tank 1, preventing wastewater from passing through the gap between the filter screen 3 and the wastewater tank 1, thereby improving the filtration effect on the wastewater.

[0030] Further improvements include, for example Figure 1 As shown, there are at least two filter screens 3. Each filter screen 3 is arranged at intervals along the direction from the water inlet pipe 102 to the water outlet pipe 101. Each filter screen 3 is independently driven to lift by a lifting power component 2.

[0031] Specifically, the filtration device is equipped with two filter screens 3. During normal use, both filter screens 3 are installed in the wastewater tank 1 at the same time, and the wastewater is filtered by both filter screens 3 simultaneously, which can improve the filtration effect. When the filter screens 3 need to be cleaned, one of the filter screens 3 can be removed for cleaning, while the other filter screen 3 can continue to work inside the wastewater tank 1. In this way, the filtration device can continue to operate normally while the filter screens 3 are being cleaned, thereby improving the filtration efficiency of the filtration device.

[0032] Further improvements include, for example Figure 2 As shown, the lifting power component 2 is a hydraulic cylinder, and the lifting end of the hydraulic cylinder is connected to the filter screen 3 through the bearing 201.

[0033] Further improvements include, for example Figure 3 and 5As shown, the filter screen 3 includes a flexible outer frame 302, which is rectangular in shape. Two support members are provided on the inner side of the outer frame 302. The two support members are distributed along the two diagonals of the outer frame 302, and the ends of the support members are fixedly connected to the corners of the outer frame 302. Multiple first mesh lines 305 and multiple second mesh lines 306 are distributed on the inner side of the outer frame 302. Each first mesh line 305 and each second mesh line 306 is located in two mutually parallel planes. The first mesh lines 305 and the second mesh lines 306 abut against each other and are arranged to intersect to form a mesh structure.

[0034] Specifically, the outer frame 302 can be made of thin stainless steel sheet. When not under stress, all four sides of the outer frame 302 bend inwards; when under stress, the four sides of the outer frame 302 are taut. When the filter screen 3 is in normal use, the outer frame 302 is supported by two support members, keeping its four sides taut. This means that the first mesh wire 305 and the second mesh wire 302 fixedly connected to the inner side of the outer frame 302 are also taut. At this time, the mesh structure formed by the combination of the first mesh wire 305 and the second mesh wire 302 can effectively filter the filter screen. The sediment in the wastewater is filtered out, and the first mesh wire 305 and the second mesh wire 302 have sufficient strength to withstand the tension of the outer frame 302 and the impact of the wastewater without deformation. When it is necessary to clean the filter screen 3, the support is shortened, so that the outer frame 302 returns to its bent state. At this time, the first mesh wire 305 and the second mesh wire 302 are in a relaxed state, which makes the mesh structure formed by the two larger, making it easier to clean the sediment stuck inside the mesh, thereby improving the convenience and cleaning effect of cleaning the filter screen 3.

[0035] Further improvements include, for example Figure 4 As shown, the support includes a threaded sleeve 304 and two threaded rods 303. One end of each threaded rod 303 is fixedly connected to one of the two corners of the outer frame 302, and the other end of each threaded rod 303 is threadedly engaged with the threaded sleeve 304. The threads of the two threaded rods 303 are in opposite directions.

[0036] Specifically, by turning the threaded sleeve 304, the two threaded rods 303 can move closer to or further away from each other, thereby achieving the extension and shortening of the support. When the support extends, the support can be stretched open by the outer frame 302, so that the outer frame 302 is in a taut state. At the same time, the outer frame 302 pulls the first mesh wire 305 and the second mesh wire 302, so that they are also in a taut state. When the support shortens, the outer frame 302 returns to a bent state, and the first mesh wire 305 and the second mesh wire 302 lose tension and are in a slack state.
