Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to an adjustable liquid filter. Background Art

[0002] Liquid filters are widely used in the fields of liquid-solid separation, filtration and purification, such as sewage and liquid purification. After a period of use, the filter residue blocked in the liquid will cover the filter component of the liquid filter, forming a layer of filter cake on the filter surface of the filter component, which will increase the filtration resistance and seriously affect the filtration effect.

[0003] Existing adjustable liquid filters, such as the adjustable liquid filter disclosed in Chinese patent application CN219072326U, record: an adjusting screw is rotatably connected to a support ear on a filter body, in a support mechanism, an adjusting screw sleeve connected to a support ring is threadedly connected to the adjusting screw, and a support rod connected to the support ring is hinged to a fixing plate through a connecting hinge, so that the filter has an adjustable support function, and after the filter is connected to a pipeline, the position of the support mechanism relative to the filter body can be adjusted by adjusting the screw, so that the fixing plate hinged to the support rod is supported on the ground, thereby supporting the bottom of the filter, preventing the filter from being suspended in the air, preventing the connection between the filter and the pipeline from being loose, and ensuring the use of personnel.

[0004] During the use of the above-mentioned liquid filtering device, when the filter is damaged and needs to be repaired, since the equipment has only a single filter chamber, when the equipment is stopped for maintenance, the impurities and contaminants in the liquid will not be able to be removed by the filter, and the liquid filtration work will stop, resulting in a decrease in liquid quality. At this time, the fluid equipment production process is interrupted, thereby affecting subsequent production steps, which will cause the entire assembly line to stagnate, thereby reducing production efficiency. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides an adjustable liquid filter having advantages such as two filter chambers, and solves the problem that a single filter cannot work during maintenance.

[0007] (II) Technical solution

[0008] In order to achieve the above-mentioned purpose of not only solving the problem of a single filter not being able to work during maintenance, but also ensuring the ability to automatically switch operations, the utility model provides the following technical solutions: an adjustable liquid filter, comprising a filter body, a replacement mechanism installed in the filter body, for setting two chambers in the filter body for separate operation, the replacement mechanism comprising a drive motor, a sliding frame, a cylinder, a sliding push plate shaft and a first chamber, the drive motor being arranged on the upper surface of the filter body, the sliding frame being sleeved on the drive motor, the sliding frame being slidably connected in the cylinder, the sliding push plate shaft being rotatably connected to the output end of the drive motor, and the first chamber being arranged on one side of the filter body.

[0009] As a preferred solution of the adjustable liquid filter of the utility model, a second chamber is fixedly connected to a side of the filter body away from the first chamber, and a cylinder is fixedly connected between the first chamber and the second chamber.

[0010] As a preferred solution of the adjustable liquid filter of the utility model, a single-pass rotating plate is rotatably connected to the lower surface of the second chamber, and a single-pass rotating plate is rotatably connected to the lower surface of the first chamber.

[0011] As a preferred solution of the adjustable liquid filter of the utility model, a propeller is sleeved on one end of the sliding push plate shaft, and a filter screen is sleeved on the single-pass rotating plate.

[0012] As a preferred solution of the adjustable liquid filter of the utility model, limit blocks are provided on both sides of the sliding push plate shaft, the limit blocks are slidably connected in the limit grooves, and the limit grooves are provided in the half gears.

[0013] As a preferred solution of the adjustable liquid filter described in the utility model, the half gear is meshed with a driving gear, the driving gear is rotatably connected to the lower surface of the filter screen, the driving gear is meshed with a driven gear, and the lower surface of the driven gear is fixedly connected to the upper surface of the single-pass rotating plate.

[0014] Compared with the known prior art, the technical solution provided by the utility model has the following advantages:

[0015] Beneficial effects:

[0016] 1. The output end of the driving motor is used to drive the sliding push plate shaft to rotate the half gear, which drives the meshing driving gear to rotate on the filter screen, so that the meshing driven gear drives the single-pass rotating plate to rotate 180 degrees, so that the first chamber and the second chamber in the filter body are used alternately. Using two liquid filters back and forth can balance their loads and prevent a single filter from being subjected to excessive working pressure for a long time. When one of the filters is damaged, the other filter can be used to work, effectively avoiding the situation where the liquid stops filtering and ensuring that the entire assembly line can work normally.

[0017] 2. The baffle on the lower surface of the limit block pushes the half gear to slide upward, and the cooperation of the limit block and the limit groove plays a limiting role. When one of the first chamber and the second chamber in the filter body is under maintenance, the cylinder is set to pull the sliding frame to drive the drive motor to move downward, so that the sliding push plate shaft drives the half gear to disengage from the driven gear, and the single-pass rotating plate stops working on the cavity that is not under maintenance. After maintenance, the teeth of the half gear are rotated to the side away from the driving gear and fall down, so that the equipment can filter the liquid, thereby improving the working efficiency of the equipment.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model is further described below in conjunction with embodiments.

[0026] Example 1

[0028] A second chamber 206 is fixedly connected to one side of the filter body 100 away from the first chamber 205, and a cylinder 203 is fixedly connected between the first chamber 205 and the second chamber 206. By fixing the cylinder 203 to the first chamber 205 and the second chamber 206, a limiting effect is exerted on the drive motor 201.

[0029] During use, the output end of the driving motor 201 is used to drive the sliding push plate shaft 204 to rotate the half gear 212, which drives the meshing driving gear 213 to rotate on the filter screen 209, so that the meshing driven gear 214 drives the single-pass rotating plate 207 to rotate 180 degrees, so that the first chamber 205 and the second chamber 206 in the filter body 100 are used alternately. Using two liquid filters back and forth can balance their loads and prevent a single filter from being subjected to excessive working pressure for a long time.

[0030] Example 2

[0031] Reference Figure 1-4, which is the second embodiment of the utility model, provides an adjustable liquid filter, which includes a second chamber 206 whose lower surface is rotatably connected to a single-pass rotating plate 207, and a first chamber 205 whose lower surface is rotatably connected to a single-pass rotating plate 207. By rotating the single-pass rotating plate 207, when the through hole on the single-pass rotating plate 207 rotates to below the second chamber 206, the second chamber 206 filters the liquid. When the through hole on the single-pass rotating plate 207 rotates to below the first chamber 205, the second chamber 206 stops working and the first chamber 205 starts to filter the liquid.

[0032] A propeller 208 is sleeved on one end of the sliding push plate shaft 204, and a filter screen 209 is sleeved on the single-pass rotating plate 207. Water is extracted by the rotation of the propeller 208. The filter screen 209 is set to prevent foreign matter from entering the filter body 100, thereby protecting the equipment.

[0033] Limiting blocks 210 are provided on both sides of the sliding push plate shaft 204, and the limiting blocks 210 are slidably connected in the limiting grooves 211, and the limiting grooves 211 are provided in the half gear 212. The half gear 212 is pushed to slide upward by the baffle on the lower surface of the limiting block 210. The cooperation between the limiting block 210 and the limiting groove 211 plays a limiting role. When one of the first chamber 205 and the second chamber 206 in the filter body 100 is under maintenance, the driving motor 201 is driven downward by pulling the sliding frame 202 through the setting of the cylinder 203, so that the sliding push plate shaft 204 drives the half gear 212 to disengage from the driven gear 214, and the single-pass rotating plate 207 stops working on the cavity that is not under maintenance, so that the equipment can filter the liquid, thereby improving the working efficiency of the equipment.

[0034] The half gear 212 is meshed with a driving gear 213, which is rotatably connected to the lower surface of the filter screen 209. The driving gear 213 is meshed with a driven gear 214, and the lower surface of the driven gear 214 is fixedly connected to the upper surface of the single-pass rotating plate 207. The rotation of the sliding push plate shaft 204 drives the half gear 212 to rotate, driving the meshed driving gear 213 to rotate on the filter screen 209, so that the meshed driven gear 214 drives the single-pass rotating plate 207 to rotate 180 degrees, thereby making the entire production line more automated.

[0035] During use, the baffle on the lower surface of the limit block 210 pushes the half gear 212 to slide upward, and the cooperation between the limit block 210 and the limit groove 211 plays a limiting role. When one of the first chamber 205 and the second chamber 206 in the filter body 100 is under maintenance, the cylinder 203 is set to pull the sliding frame 202 to drive the drive motor 201 to move downward, so that the sliding push plate shaft 204 drives the half gear 212 to disengage from the driven gear 214, and the single-pass rotating plate 207 stops working on the cavity that is not under maintenance. After maintenance, the teeth of the half gear 212 are rotated to the side away from the driving gear 213 and fall down, so that the equipment can filter the liquid, thereby improving the working efficiency of the equipment.
