Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically a centrifuge slag discharge port structure. Background Technology

[0002] A horizontal screw centrifuge is a horizontal, continuously operating sedimentation device with screw discharge. The working principle of this type of centrifuge is as follows: the drum and screw rotate at high speed in the same direction with a certain differential speed. The material is continuously introduced into the inner cylinder of the conveying screw through the feed pipe, accelerated, and then enters the drum. Under the action of centrifugal force, the heavier solid phases are deposited on the drum wall, forming a sludge layer. The conveying screw continuously pushes the deposited solids to the conical end of the drum, where they are discharged from the machine through the sludge discharge port. The lighter liquid phases form an inner liquid ring, continuously overflowing from the large end overflow port of the drum and being discharged from the machine through the liquid discharge port.

[0003] The current slag discharge port structure is controlled by a built-in electric valve. When carrying out maintenance and cleaning work, opening the maintenance port can only be used to operate on the slag discharge channel. If detailed maintenance and cleaning of the inside of the drum is required, the entire valve needs to be removed, which is quite inconvenient. Utility Model Content

[0039] 2. When the sealing door and access port are closed, the locking plate installed on the edge of the sealing door engages with the locking slot of the corresponding locking block. By grasping the handle and pulling the lever, the locking block is rotated, causing it to abut against the front surface of the locking plate. At the same time, the spring pin engages with the locking pin slot, locking the overall structure and sealing the sealing door at the access port. Simultaneously, the sliding engagement of the locking plate and the locking slot, and the sliding hinge of the hinged slide and the second base, allow the sealing door to move forward a certain distance when opened. This facilitates the simultaneous removal of the passage sealing plate when opening the sealing door, avoiding any interference between the passage sealing plate and the access port during opening and closing.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Please see Figure 1-7 In this embodiment of the present invention, a centrifuge slag discharge port structure includes a discharge structure 1, a channel sealing plate 2, and a sealing structure 3. The discharge structure 1 includes a slag discharge channel 101, a connecting interface 103 on the rear side of the slag discharge channel 101, and an inspection port 107 on the front side of the slag discharge channel 101. The sealing structure 3 includes a sealing block 301, which is arranged in a ring at equal angles and fixedly installed on the edge of the inspection port 107. The sealing block 301 encapsulates a sealing door 315 at the inspection port 107, and the sealing door 315 is hinged to one side of the inspection port 107. The channel sealing plate 2 is fixedly installed in the middle of the sealing door 315.

[0050] Specifically, the entire device is installed on one side of the conical drum of the LWL type horizontal spiral discharge filter centrifuge, and the large opening of the drum is connected to the interface 103 to complete the installation of the overall structure. The opening on one side of the drum is sealed by the channel sealing plate 2. After the centrifugation work is achieved by the rotation of the drum, the channel sealing plate 2 is retracted based on the sealing door 315, and the opening on one side of the drum is opened for material discharge. At the same time, the channel sealing plate 2 is combined with the sealing structure 3, and the sealing block 301 stabilizes the closed state of the sealing door 315 to ensure the stability of the channel sealing plate 2 during operation. When the inspection port 107 is opened for maintenance, the opening on one side of the drum can be opened at the same time. While the slag discharge channel 101 is being inspected and cleaned, the inside of the drum can also be inspected and cleaned.

[0051] Example 1

[0052] like Figure 3 As shown, in this embodiment, the discharge structure 1 further includes a slag outlet 102, a sealing plate 104, a slag channel 105, and a docking slip ring 106.

[0055] In practice, during normal operation, the electric actuator 205 drives the integrated bracket 201 to move back and forth. With the auxiliary limiting of the guide rod 204, the sealing plate unit 202 is controlled to disengage from and engage with the slag channel 105, thus acting as the original valve structure to control the sealing and discharge of slag.

[0056] Example 2

[0057] Based on Embodiment 1, in order to supplement the specific method of opening the sealing door 315 and the passage sealing plate 2 as a whole, which was not mentioned in Embodiment 1.

The sealing slot 302 is located at the bottom of the sealing block 301; the locking plate 303 is engaged inside the sealing slot 302; the upper side of the first base 304 is fixedly connected to the locking plate 303, and the first base 304 is arranged in a ring at equal angles and fixedly installed on the edge of the sealing door 315; the stop block movable groove 305 is located on the upper surface of the sealing block 301 and communicates with the sealing slot 302; the locking pin slot 306... 06 is opened on both sides of the front opening of the abutment block movable groove 305; the blocking abutment block 307 is rotatably installed in the abutment block movable groove 305, and the blocking abutment block 307 moves against the front surface of the card plate 303; the pull rod 308 is fixedly installed on the rear edge of the upper surface of the blocking abutment block 307; the abutment plate 309 is fixedly installed on the upper end of the pull rod 308; the spring pin 310 is inserted and installed at both ends of the abutment plate 309; the pull ring 311 is fixedly installed on the upper end of the spring pin 310; the grip handle 312 is fixedly installed in the middle of the upper surface of the abutment plate 309; the hinged slide 313 is fixedly installed on the upper and lower sides of the blocking block 301 on one side of the inspection port 107; the second base 314 is fixedly installed on one side edge of the sealing door 315, and the second base 314 and the hinged slide 313 are slidably hinged.

[0059] In specific implementation, when the sealing door 315 is closed with the access port 107, the locking plate 303 installed on the edge of the sealing door 315 is inserted into the locking slot 302 of the corresponding blocking block 301. By grasping the handle 312 and pulling the lever 308, the blocking block 307 is rotated, so that the blocking block 307 abuts against the front surface of the locking plate 303. At the same time, the spring pin 310 is inserted into the locking pin slot 306 to lock the overall structure and seal the sealing door 315 at the access port 107. Meanwhile, the sliding engagement of the locking plate 303 and the locking slot 302 and the sliding hinge of the hinged slide block 313 and the second base 314 allow the sealing door 315 to move forward a certain distance when it is opened. This makes it convenient to remove the passage sealing plate 2 at the same time when the sealing door 315 is opened, avoiding any interference between the passage sealing plate 2 and the access port 107 during opening and closing.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
