Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a pre-coating filtering device with a filter aid adding structure. Background Art

[0002] Pre-coat filters are an advanced filtration system that pre-coats the filter medium with a filter aid (such as diatomaceous earth or cellulose) to form a dense pre-coat layer. This pre-coat layer effectively blocks tiny particles and impurities in the liquid, achieving high-precision filtration. Pre-coat filters play a vital role in industrial production.

[0003] The mixing tank is a key component in precoat filtration systems. Its primary function is to mix and prepare the filter aid and liquid mixture for subsequent precoat formation on the filter medium. A mixing tank typically consists of a housing, a stirring mechanism, an inlet, and a discharge port. The housing holds the liquid and filter aid to be mixed, while the stirring mechanism ensures a thorough mixing of the two. The inlet is used to add the liquid and filter aid, while the discharge port discharges the mixed material for subsequent filtration.

[0004] However, when adding filter aids to the mixing box, workers are required to add them gradually and in appropriate amounts multiple times. This operation method not only increases the complexity of the workflow, but also places a considerable burden on the operators. Utility Model Content

[0029] Example 1

[0030] like Figures 1 to 4The embodiment of the present application shown provides a pre-coat filtration device with a filter aid adding structure, including: a filter aid receiving tank 1 and a mixing box 2; the upper surface of the mixing box 2 is provided with a feed port 21 suitable for the entry of the filter aid; the filter aid receiving tank 1 is arranged above the mixing box 2, and the filter aid receiving tank 1 is provided with a first tube body 11 for connecting the filter aid receiving tank 1 and the feed port 21; a spiral conveying device 31 for conveying the filter aid is provided at the bottom of the filter aid receiving tank 1; the spiral conveying device 31 passes through the filter aid receiving tank 1, one end of the spiral conveying device 31 is connected to the drive motor 32, and the other end of the spiral conveying device 31 is located in the first tube body 11; the spiral conveying device 31 is electrically connected to the control device 33.

[0031] More preferably, in the embodiments provided in this application, Figure 1 As shown, a rectangular mixing box 2 is placed horizontally on the base 6, and the feed port 21 of the mixing box 2 is located on the right part of the upper surface of the mixing box 2. A filter aid receiving tank 1 with a "V"-shaped cross-section is provided on the left side of the upper part of the mixing box 2. A scale 12 feet is provided on the inner wall of the filter aid receiving tank 1 to facilitate recording the amount of filter aid used. A first tube body 11 is provided on the right side of the filter aid receiving tank 1. One end of the first tube body 11 is connected to the filter aid receiving tank 1, and the other end is located above the feed port 21. A screw conveying device for driving the filter aid receiving tank 1 is provided on the left side of the mixing box 2. A driving motor 32 is provided at 31, and the spiral conveying device 31 is provided at the bottom of the filter aid receiving tank 1. The spiral conveying device 31 adopts a screw conveyor in the prior art. The spiral conveying device 31 passes through the filter aid receiving tank 1 and extends into the first tube body 11. A control device 33 electrically connected to the driving motor 32 is provided on the base 6. The control device 33 is provided with a start and a pause button, which are respectively used to control the start and pause of the spiral conveying device 31. A second baffle 22 for covering the feed port 21 is also provided at the feed port 21.

[0032] During use, the operator adds a sufficient amount of filter aid (such as cellulose filter aid) to the filter aid storage tank 1, removes the second baffle 22 to open the feed port 21, and then starts the screw conveying device 31 through the control device 33. Under the transportation of the screw conveying device 31, the granular filter aid is transported into the first tube body 11 and falls into the feed port 21 from the opening of the first tube body 11. The operator observes the scale 12 in the metering filter aid storage tank 1. After an appropriate amount of filter aid enters the mixing box 2, the operator closes the screw conveying device 31 through the control device 33, stops the transportation of the filter aid, and covers the second baffle 22 to prevent liquid splashing during mixing. When filter aid needs to be added later, the operation can be repeated.

[0033] In this embodiment, by providing a screw conveying device 31 between the filter aid storage tank 1 and the mixing box 2, the filter aid can be added quickly in batches, which reduces the manpower consumption required for multiple additions of the filter aid and improves the efficiency of the filter aid addition.

[0034] Example 2

[0035] Further, based on the above embodiment 1, as Figure 4 As shown, a first channel 4 is further provided between the feed port 21 and the first tube body 11. The upper surface of the first channel 4 is a slope extending from the first tube body 11 toward the feed port 21. A first baffle 5 is provided at the tube mouth of the first tube body 11 near the first channel 4. The first baffle 5 is detachable and inserted between the first tube body 11 and the first channel 4. The thickness of the first baffle 5 is the same as the distance between the first tube body 11 and the first channel 4.

[0036] During use, after adding an appropriate amount of filter aid, the operator can first use the first baffle 5 to isolate the connection between the first tube 11 and the first channel 4, and then use the control device 33 to close the screw conveying device 31, which can further improve the effect of adding the filter aid.

[0037] In this embodiment, by providing a detachable first baffle 5 at the pipe mouth of the first tube body 11, a quick pause of the addition of the filter aid is achieved, the precision control effect of the addition of the filter aid is improved, and the simple structure is easy to produce.
