[0002] In the current pulp making process, the rotary concentration adjuster is a key equipment, and its efficient operation is crucial to ensure the stability of the production process and the control of pulp quality. However, the traditional rotary concentration adjuster faces a significant challenge when it is actually used in the workshop: the cooling water provided by the workshop often contains a large amount of impurities. These impurities easily accumulate and clog the sealing water pipeline (cooling pipeline) during the circulation process, resulting in a decrease in the cooling effect, which in turn affects the normal working environment temperature and performance of the rotary concentration adjuster. This long-standing sealing water problem not only increases the maintenance cost and downtime of the equipment, but also causes the rotary concentration adjuster to be in a non-optimal operating state for a long time, affecting the accuracy of pulp concentration detection and production efficiency.

[0041] See also Figures 1 to 5 The present embodiment provides a rotary thickening device 30 having a filter chamber 10, comprising:

[0042] The filter chamber 10 comprises: a housing 11 and a filter screen 12, wherein the housing 11 has a receiving chamber 13 and a first opening 14 at the top, the filter screen 12 is placed in the receiving chamber 13, and the filter screen 12 divides the receiving chamber 13 into a filtering chamber 131 and a flushing chamber 132;

[0043] The filter cover 20 comprises a cover body 21 and a rotating pipeline 22. The cover body 21 is provided on the first opening 14. A water inlet hole 23 and a water outlet hole 24 are provided on the cover body 21. The apertures of the water inlet hole 23 and the water outlet hole 24 are equal, and the water outlet hole 24 is connected to a water outlet pipeline 25, and the water inlet hole 23 is connected to a water inlet pipeline 26. The rotating pipeline 22 is rotatably provided in the cover body 21, one end of the rotating pipeline 22 is adapted to the water inlet hole 23, and the other end of the rotating pipeline 22 is connected to the filter chamber 131 through the filter screen 12.

[0044] Rotary concentrated adjustment 30, the water outlet hole 24 on the filter cover 20 is connected to the cooling pipeline on the rotary concentrated adjustment 30 through the water outlet pipeline 25;

[0045] The water storage tank 40 has a water storage cavity 41 therein, and the water storage tank 40 is provided with a second opening 42 which is in communication with the water storage cavity 41 ; the water storage tank 40 is placed on the water inlet pipeline 26 , and the water storage cavity 41 is in communication with the water inlet pipeline 26 .

[0046] The filter chamber 10 includes: the shell 11 and the filter screen 12. The shell 11 has the accommodating chamber 13 inside, and the top of the shell 11 is provided with the first opening 14, and the accommodating chamber 13 is in communication with the first opening 14. The filter screen 12 is placed in the accommodating chamber 13, and the accommodating chamber 13 is divided into the filter chamber 131 and the flushing chamber 132; wherein the flushing chamber 132 covers the filter chamber 131, and cooling water enters the filter chamber 131 from the flushing chamber 132, and then is discharged from the filter chamber 131.

[0047] Furthermore, the filter chamber 131 is used to accommodate filter elements, filter media and other filtering materials for filtering salts, colloids and microorganisms in water; the flushing chamber 132 is used to filter particles and suspended matter in water. Specifically, the water flow forms a vortex in the flushing chamber 132, and the suspended matter and particles will be deposited at the bottom of the flushing chamber 132 under the action of gravity and the vortex.

[0048] The filter cover 20 is tightly covered on the first opening 14 of the filter bin 10, the water inlet hole 23 and the water outlet hole 24 are arranged through the side wall of the cover body 21, and the apertures of the water inlet hole 23 and the water outlet hole 24 are equal, the water inlet hole 23 is connected to the water inlet pipe 26, and the water outlet hole 24 is connected to the water outlet pipe 25. The rotating pipe 22 is rotatably arranged in the filter cover 20, and one end of the rotating pipe 22 is rotatably connected to the filter screen 12, that is, the rotating pipe 22 is always connected to the filter chamber; when the rotating pipe 22 is in the first position, the end of the rotating pipe 22 away from the filter screen 12 is connected to the water outlet hole 24, at this time, the water flows from the water inlet hole 23 into the flushing chamber 132, enters the filter chamber 131 through the filter screen 12, and then flows to the water outlet hole 24 through the rotating pipe 22 to filter the cooling water. When the rotating pipe 22 is in the second position, the end of the rotating pipe 22 away from the filter screen 12 is connected to the water inlet 23. At this time, water flows into the filter chamber 131 from the water inlet 23, and enters the flushing chamber 132 through the filter screen 12 to clean the filter screen 12. Further, the rotating pipe 22 is an "L"-shaped pipe.

[0049] The central axis of the water inlet 23 coincides with the central axis of the water outlet 24. The angle between the water inlet 23 and the water outlet 24 is 180°.

[0050] The rotary thickening agent 30 receives the clean cooling water from the water outlet 24 through the cooling pipeline thereon, so as to realize the continuous cooling of the working environment and ensure the normal operation of the equipment.

[0051] The water storage tank 40 is located on the water inlet pipeline 26, and has a water storage cavity 41 inside the water storage tank 40. The second opening 42 is opened on the side wall of the water storage tank 40 to facilitate the entry and discharge of cooling water, and the second opening 42 is placed at the bottom of the water storage tank 40. The water storage tank 40 is used to increase the water pressure to improve the efficiency during backwashing. Specifically, when the rotating pipeline 22 is placed in the second position, the valve is opened to release the pressure, and the high-pressure water flow will quickly wash the filter screen 12 wall. Further, in actual operation, the cooling system is first turned off (that is, the coolant cannot flow into the cooling pipeline at this time), and the coolant enters from the second opening 42 at the bottom of the water storage tank 40 until it cannot enter, and then the valve is closed. At this time, in the water storage cavity 41, the top is compressed air and the bottom is water; when backwashing is required, the valve is opened to achieve the effect of pressurization.

[0052] In actual operation, before work, the cooling water provided by the workshop first enters the water storage tank 40 for pressure storage, and the valve is closed; during work, the cooling water enters the water inlet hole 23 of the filter cover 20 through the water inlet pipe 26, and then enters the flushing chamber 132 to precipitate particles and suspended matter, and then enters the filter chamber 131 to filter salts, and finally is discharged from the water outlet 24 through the rotating pipe 22; after work, the rotating pipe 22 is rotated to connect the rotating pipe 22 with the water inlet hole 23, and the valve is opened for backwashing.

[0053] Different from the prior art, the above technical solution effectively intercepts and precipitates large particles of impurities and suspended matter in the cooling water through the arrangement of the filter 12 and the flushing chamber 132, and further removes tiny impurities such as salts, colloids and microorganisms in the water by using the filter element and filter material in the filter chamber 131, thereby ensuring the cleanliness and purity of the cooling water supplied to the rotary concentration adjustment 30. In addition, the automatic flushing function of the filter 12 is realized through the arrangement of the rotating pipeline 22, thereby avoiding the occurrence of the filter 12 clogging problem and ensuring the continuity and stability of the filtering effect. At the same time, the efficiency of backwashing is improved through the arrangement of the water storage tank 40.

[0054] According to some embodiments of the present application, referring to Figure 1 , Figure 2 , Figure 4 as well as Figure 5 , further comprising: a drain cover 50 , a drain through hole 15 is provided through the bottom of the shell 11 , and the drain cover 50 is covered on the drain through hole 15 .

[0055] The drain hole 15 passes through the bottom of the housing 11, and allows the impurities and particles deposited at the bottom of the flushing chamber 132 during the filtration process to be discharged. The drain cover 50 is sealed to the drain hole 15 to ensure that the system remains sealed when draining is not required.

[0056] When a certain amount of impurities and particulate matter accumulates inside the filter bin 10, it is necessary to perform drainage operation regularly. At this time, the drainage cover 50 can be opened, and the impurities deposited at the bottom can be flushed out of the drainage through hole 15 by the water flow inside the flushing chamber 132 or the flushing water source provided by the outside. After the drainage is completed, the drainage cover 50 is re-covered to restore the sealing state of the system.

[0057] The provision of the drainage cover 50 makes the drainage operation of the filter chamber 10 more convenient and efficient. By draining the sewage regularly, it is possible to effectively prevent the excessive accumulation of impurities in the flushing chamber 132, thereby affecting the filtering effect and flushing efficiency. At the same time, it also reduces equipment failures and maintenance costs caused by the accumulation of impurities.

[0058] According to some embodiments of the present application, it further includes: a power source 70, which is transmission-connected to the rotating pipeline 22, and the power source 70 is used to drive the rotating pipeline 22 to rotate.

[0059] The power source 70 is in driving connection with the rotating pipeline 22, and is used to drive the rotating pipeline 22 to perform a rotating motion. The power source 70 can be a device capable of providing rotating power, such as an electric motor or a pneumatic motor.

[0060] When backwashing or adjusting the position of the rotating pipe 22 is required, the power source 70 is started, and the rotating power is transmitted to the rotating pipe 22 through the transmission device, so that it rotates in a predetermined direction. The rotating motion of the rotating pipe 22 not only helps to wash away the impurities attached to the surface of the filter screen 12, but also allows the rotating pipe 22 to be placed in different working positions (such as being connected to the water inlet 23 or the water outlet 24) as needed.

[0061] The setting of the power source 70 realizes the automatic control of the rotating pipeline 22, improves the intelligence level and operation convenience of the equipment, and at the same time, ensures the stability of the flushing effect and the cleanliness of the filter screen 12, and prolongs the service life of the equipment.

[0062] According to some embodiments of the present application, referring to Figure 1 and Figure 4 , further comprising: a pressure gauge 60, wherein the pressure gauge 60 is placed on the cover body 21, and the detection end of the pressure gauge 60 is placed in the rotating pipeline 22, and the pressure gauge 60 is used to detect the water pressure passing through the rotating pipeline 22.

[0063] The pressure gauge 60 is mounted on the cover 21, and the detection end of the pressure gauge 60 extends into the interior of the rotating pipeline 22. The pressure gauge 60 is used to monitor and display the water pressure value passing through the rotating pipeline 22 in real time.

[0064] When cooling water enters the rotating pipeline 22 through the water inlet pipeline 26, the water pressure inside the pipeline will change. The pressure gauge 60 senses this change through its detection end and displays the water pressure value in a visual manner. The operator can judge whether the current water pressure state is normal and whether corresponding adjustment measures need to be taken according to the reading on the pressure gauge 60.

[0065] The design of the pressure gauge 60 enables the operator to intuitively understand the water pressure inside the rotating pipeline 22, so as to timely discover and solve potential water pressure problems. This helps to ensure the stable operation of the equipment and extend its service life. At the same time, it also provides an important reference for the maintenance and care of the equipment.

[0066] According to some embodiments of the present application, referring to Figure 2 and Figure 5 The filter screen 12 has a filter chamber 131 inside and a third opening 121 on the top, and the third opening 121 is flush with the first opening 14 , and one end of the rotating pipe 22 away from the water inlet hole 23 or the water outlet hole 24 is flush with the third opening 121 .

[0067] The filter screen 12 has the filter chamber 131 inside, and the filter screen 12 has the third opening 121 on the top, the third opening 121 is flush with the first opening 14, and the flushing chamber 132 covers the filter screen 12; that is, the flushing chamber 132 covers the area of ​​the filter chamber 131 having the filter screen 12. One end of the rotating pipe 22 away from the water inlet 23 or the water outlet 24 is rotatably connected to the filter screen 12, and the channel in the rotating pipe 22 is connected to the third opening 121.

[0068] The first opening 14 is flush with the third opening 121 , ensuring that during the rotation process, the coolant can smoothly enter or exit the filter chamber 131 from this end of the rotating pipeline 22 .

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
