Description

Technical Field

[0001] This utility model relates to the technical field of slurry screening equipment, and in particular to a slurry pressure screen. Background Technology

[0002] In industries such as papermaking and chemicals, pulp pressure screens serve as crucial screening equipment, playing a vital role in separating impurities from pulp and ensuring the quality of the finished product. They filter the pulp through a screen drum, selecting out the pulp that meets the requirements while retaining impurities. However, in practical use, existing pulp pressure screens have significant shortcomings.

[0003] On the one hand, impurities in the slurry easily adhere to the surface of the screen drum, causing screen clogging, reducing screening efficiency, and affecting production continuity. On the other hand, traditional screen drum cleaning methods often require stopping the machine and disassembling the equipment, which is not only cumbersome and consumes a lot of manpower and time, but frequent disassembly can also damage the equipment and shorten its service life. In addition, the existing cleaning devices are not reasonably designed in terms of structure, making it difficult to guarantee the cleaning effect and failing to meet the needs of high-efficiency production.

[0004] Therefore, there is an urgent need for a slurry pressure screen that can effectively solve the problem of screen drum clogging, is easy to clean, and does not affect production efficiency. Utility Model Content

[0029] Example 1

[0030] Reference Figures 1-4 This invention provides a slurry pressure screen that can clean the screen drum 104 without shutting down the equipment. The screen includes a body unit 100, which comprises a capacity cylinder 101, a rotor 102 disposed inside the capacity cylinder 101, and a drive assembly 103. The drive assembly 103 drives the rotor 102 to rotate, and the rotor 102 is located at the output end of the drive assembly 103. The screen drum 104, fitted around the outer periphery of the rotor 102, is rotatably mounted inside the capacity cylinder 101. The drive assembly 103 provides power to the rotor 102, enabling it to drive the screen drum 104 to rotate, thereby achieving slurry screening. During rotation, the screen drum 104 can screen out slurry that meets the requirements.

[0031] The internal cleaning unit 200 includes a collection bin 201 fixedly installed on one side of the capacity cylinder 101 and a brush body 202 located inside the collection bin 201. The function of the collection bin 201 is to collect the brush body 202 when the screen drum 104 is not being cleaned, preventing the brush body 202 from being contaminated by slurry. The collection bin 201 is equipped with a translation component 203 for driving the lateral displacement of the brush body 202. A mounting groove 204 is provided near the top of the collection bin 201 close to the capacity cylinder 101. A removable partition 205 is slidably inserted into the mounting groove 204, isolating the collection bin 201 from the capacity cylinder 101 when closed. This ensures that during normal screening, slurry will not enter the collection bin 201 and affect the brush body 202.

[0032] The top of the capacity cylinder 101 is provided with a feed inlet 101a, which allows the slurry to smoothly enter the capacity cylinder 101 for screening. A slurry outlet 101b is provided on one side of the capacity cylinder 101 for discharging the qualified slurry after screening. A waste discharge outlet 101c is provided at the bottom of the capacity cylinder 101, located between the rotor 102 and the screen drum 104, to discharge the trapped impurities. The feed inlet 101a, slurry outlet 101b, and waste discharge outlet 101c are all connected to the interior of the capacity cylinder 101, ensuring the smooth operation of the slurry screening process.

[0033] First, the drive assembly 103 is started, which drives the rotor 102 to rotate, thereby driving the screen drum 104 to rotate. The slurry is poured into the capacity cylinder 101 from the feed inlet 101a. During the rotation of the screen drum 104, slurry meeting the requirements passes through the screen holes on the screen drum 104 and is discharged from the slurry outlet 101b, while impurities are trapped inside the screen drum 104 and discharged from the waste discharge outlet 101c. When it is necessary to clean the screen drum 104, the partition 205 is pulled out, and the translation assembly 203 is started. The translation assembly 203 drives the brush body 202 to move towards the screen drum 104, so that the brush body 202 contacts the screen drum 104 to clean its surface. After cleaning, the brush body 202 is retracted and the partition 205 is inserted.

[0034] This embodiment achieves the basic screening function of slurry and includes an internal cleaning unit 200, which can clean the screen drum 104 to a certain extent, ensuring its normal operation. The arrangement of the feed inlet 101a, slurry outlet 101b, and waste discharge outlet 101c ensures that the slurry screening and impurity discharge processes are carried out in an orderly manner, improving screening efficiency.

[0035] Example 2

[0036] Reference Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, a base 105 is fixedly connected to the bottom of the capacity cylinder 101. The function of the base 105 is to provide stable support for the entire device, ensuring that the device will not shake during operation and improving the stability of the device.

[0037] The drive assembly 103 includes a drive motor 103a fixedly mounted on the base 105. The drive motor 103a serves as a power source, and a drive roller 103b is fixedly mounted at its output end. The bottom end of the rotor 102 rotates through the capacity cylinder 101 and extends to the outside of the capacity cylinder 101. A driven roller 103c is fixedly connected to the bottom end of the rotor 102. A toothed belt 103d drives the drive roller 103b and the driven roller 103c. The toothed belt 103d ensures the stability and accuracy of power transmission, enabling the power of the drive motor 103a to be efficiently transmitted to the rotor 102, driving the rotor 102 to rotate.

[0038] A turbulence block 102a is provided on the rotor 102. During the rotation of the rotor 102, the turbulence block 102a agitates the slurry, making the slurry more evenly distributed within the capacity cylinder 101, thereby improving the screening effect. The rotor 102 is also equipped with a synchronization component 106 for synchronizing the rotation of the screen drum 104. The synchronization component 106 includes a horizontally positioned first electric push rod 106a. A rubber friction block 106b is fixedly connected to the output end of the first electric push rod 106a. When the first electric push rod 106a is extended, the friction block 106b contacts and engages with the inner wall of the screen drum 104. The function of the synchronization component 106 is to synchronize the rotation of the screen drum 104 with the rotor 102 during cleaning, allowing the brush body 202 to clean the surface of the screen drum 104 more thoroughly and efficiently.

[0039] The translation component 203 includes a second electric push rod 203a, the output end of which is fixedly connected to a mounting plate 203b. The second electric push rod 203a drives the mounting plate 203b and the brush body 202 to move laterally. The brush body 202 is detachably mounted on the mounting bracket by bolts, which facilitates the replacement and maintenance of the brush body 202. The brush body 202 is slidably connected to the inner wall of the storage compartment 201, ensuring that the brush body 202 can move smoothly within the storage compartment 201.

[0040] The working surface of the brush body 202 is provided with an arc-shaped bristle array 202a that matches the outer contour of the screen drum 104. When the partition 205 is fully pulled out, the second electric push rod 203a can drive the brush body 202 to move and press against the outer surface of the screen drum 104. The arc-shaped bristle array 202a can better fit the surface of the screen drum 104 and improve the cleaning effect.

[0041] Operating Procedure: Connect the equipment to the power supply and start the drive motor 103a. The drive motor 103a drives the drive roller 103b to rotate, which in turn causes the driven roller 103c and rotor 102 to rotate via the toothed belt 103d, thereby driving the screen drum 104 to rotate. Pour the slurry into the capacity cylinder 101 through the feed inlet 101a. During the rotation of the rotor 102, the turbulence block 102a agitates the slurry, ensuring its uniform distribution within the capacity cylinder 101. The rotating screen drum 104 filters the slurry. Slurry meeting the requirements passes through the screen holes of the screen drum 104 and flows out from the slurry outlet 101b; impurities are trapped inside the screen drum 104 and ultimately discharged from the waste discharge outlet 101c. When cleaning the screen drum 104 is required, pull out the partition 205 on the storage compartment 201, and start the second electric push rod 203a. The second electric push rod 203a pushes the mounting plate 203b and the brush body 202 towards the screen drum 104 until the arc-shaped bristle array 202a of the brush body 202 presses against the outer surface of the screen drum 104. At the same time, start the first electric push rod 106a to make the friction block 106b contact the inner wall of the screen drum 104. At this time, the drive motor 103a continues to work to drive the rotor 102 to rotate. The synchronization component 106 keeps the screen drum 104 rotating. The brush body 202 cleans the surface of the screen drum 104 during its rotation. After cleaning, first retract the first electric push rod 106a to disengage the friction block 106b from the screen drum 104, and then retract the second electric push rod 203a to collect the brush body 202 back into the storage compartment 201 and insert it into the partition 205.

[0042] This embodiment is a further optimization of Embodiment 1. The base 105 provides stable support for the equipment, ensuring stable operation. The toothed belt 103d transmission method makes the drive more stable and reliable. The inclusion of the turbulence block 102a makes the slurry distribution more uniform, improving the screening effect. The synchronization component 106 works in conjunction with the synchronous rotation of the screen drum 104, enabling the brush body 202 to clean the surface of the screen drum 104 more efficiently, improving the cleaning effect. The brush body 202 is detachable and installable via bolts, facilitating replacement and maintenance. The arc-shaped bristle array 202a matches the outer contour of the screen drum 104, allowing for better contact with the surface of the screen drum 104 for cleaning, further improving the cleaning effect and quality.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
