Description

Technical Field

[0001] The utility model relates to the technical field of filter screens, in particular to an air inlet filter screen for a dryer. Background Art

[0002] In textile operations, dryers are one of the indispensable equipment. The performance of dryers directly affects the quality and production efficiency of products. However, the traditional dryer air inlet design often adopts a square hole open design. This design has obvious disadvantages in an open production environment, especially in a working environment with more fibers and impurities.

[0003] Due to the open air inlet and the influence of the production environment, fibers and impurities can easily enter the evaporator of the dryer. These fibers and impurities will not only cause poor airflow inside the evaporator, affecting the drying effect, but also cause evaporator blockage over a long period of time, and even trigger high and low pressure alarms for the refrigerant, causing the dryer to stop, seriously affecting production progress.

[0004] To solve this problem, technicians tried to install a filter at the air inlet of the dryer to filter out the fibers and impurities that came in. This measure improved the airflow inside the evaporator to a certain extent, reduced the accumulation of fibers and impurities, and improved the operating stability of the dryer.

[0005] However, in actual use, the filter also faces some problems. When the filter is covered with a lot of fibers and impurities, the filtering effect of the filter will be greatly reduced or even completely ineffective. At this time, the filter needs to be cleaned. The traditional cleaning method usually uses a brush to scrape off the fibers and impurities on the filter. However, this method requires the staff to carry a brush with them, which not only increases the burden on the staff, but also makes the operation more inconvenient.

[0006] Therefore, a dryer air inlet filter is needed to overcome the above problems. Utility Model Content

[0007] In order to solve the above problems, the embodiment of the utility model provides a dryer air inlet filter, which achieves the purpose of solving the problems raised in the background technology.

[0008] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a dryer air inlet filter, including two bases fixedly connected on both sides of the air inlet, a rotating shaft is rotatably arranged inside the base, a filter is rolled up on the rotating shaft, and a knob is fixedly connected to one end of the rotating shaft; a brush head for cleaning the filter is fixedly connected to the base.

[0009] As a further improvement of the above technical solution:

[0010] One end of the rotating shaft is rotatably connected with a connecting block, the connecting block is threadedly connected to one end of the base, and the other end of the base is provided with a through groove for accommodating the rotating shaft.

[0011] Magnetic strips are fixedly connected to both sides of the filter.

[0012] Both sides of the filter screen are provided with pressing blocks for pressing the filter screen, and pulleys are provided on the pressing blocks.

[0013] The beneficial effects of the embodiments of the utility model are:

[0014] When the filter needs to be cleaned, the staff turns the knob on one of the bases to drive the rotating shaft to retract the filter. When the filter moves, the brush head is used to clean the fibers adhered to the filter, which means that the staff no longer need to carry a brush with them to clean the filter.

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] See also Figures 1 to 4 The utility model embodiment discloses a dryer air inlet filter, comprising two bases 1 fixedly connected to both sides of the air inlet, a rotating shaft 2 is rotatably arranged inside the base 1, a filter 3 is rolled up on the rotating shaft 2, and a knob 6 is fixedly connected to one end of the rotating shaft 2;

[0022] A brush head 5 for cleaning the filter screen 3 is fixedly connected to the base 1;

[0023] When the filter 3 needs to be cleaned, the staff member turns the knob 6 on one of the bases 1 to drive the rotating shaft 2 to retract the filter 3. When the filter 3 moves, the brush head 5 is used to clean the fibers adhered to the filter 3, that is, the staff member no longer needs to carry a brush with him to clean the filter 3.

[0024] There are two bases 1. When cleaning the filter 3 for the first time, turn the knob 6 on one of the bases 1 to retract the filter 3 to one side; when cleaning the filter 3 for the second time, turn the knob 6 on the other base 1 to retract the filter 3 to the other side.

[0025] As a further illustration of this application:

[0026] One end of the rotating shaft 2 is rotatably connected with a connecting block 7, which is threadedly connected to one end of the base 1, and the other end of the base 1 is provided with a through groove 8 for accommodating the rotating shaft 2; there is a certain resistance between the connecting block 7 and the rotating shaft 2, thereby ensuring that the filter 3 can be tightly fitted at the air inlet;

[0027] In actual application, although the fibers on the filter 3 can be removed by the brush head 5, it is difficult to completely clean the dust on the filter 3 by the brush head 5, so the filter 3 needs to be cleaned regularly to remove the dust; when the filter 3 needs to be cleaned, the connecting block 7 is rotated to separate the connecting block 7 from the base 1, and the filter 3 can be disassembled at this time.

[0028] As a further illustration of this application:

[0029] Magnetic strips 4 are fixedly connected to both sides of the filter 3 to ensure that the filter 3 can fit on the air inlet.

[0030] As a further illustration of this application:

[0031] On both sides of the filter 3, there are clamping blocks 9 for clamping the filter 3. The clamping blocks 9 are fixed at the air inlet. A pulley 10 is provided on the clamping blocks 9. The sides of the filter 3 are clamped by the clamping blocks 9 to ensure that the filter 3 can fit better at the air inlet. The pulley 10 can reduce the resistance between the clamping block 9 and the filter 3, so as to facilitate the reeling of the filter 3.
