Example 2

Considering that in the process of purifying sewage, the more accumulated the sludge is between two adjacent filtering monomers 401 and in the filtering layer 27, the sludge between the filtering monomers 401 and in the filtering layer 27 needs to be cleaned and collected periodically, but under the effect of the impact compression action of the extrusion force and the combination of the viscosity of the sludge, the adjacent filtering monomers 401 are firmly adhered together, so that before the sludge is cleaned, the two adjacent filtering monomers 401 need to be separated. Based on this, the present invention further provides a monomer separation apparatus.

Referring to fig. 8, the single body separation device is disposed at one side of the plugging end of the filter 4, as shown in fig. 9, the single body separation device includes a slide seat 14, the slide seat 14 is slidably connected to the slide rail 6, a base 15 is welded above the slide seat 14, a turning plate 16 is rotatably connected to the base 15 through a pin shaft, the left side of the turning plate 16 is connected to the slide seat 14 through an elastic component (the elastic component is a spring 17, and according to actual requirements, the elastic component can also be made of rubber or other materials), the turning plate 16 forms an acute angle α with the upper surface of the slide seat 14, and the left side of the turning plate 16 forms a tilting portion 1601; the carriage 1 is provided with a drive source for driving the carriage 14 to reciprocate.

The flap 16 is connected to the chain 20, and controls the slide 14 (flap 16) to reciprocate on the slide rail 6 by controlling the forward and reverse rotation of the servo motor.

The working principle of the monomer separation device is as follows: when the filtering monomers 401 need to be separated, the extrusion force on the plurality of filtering monomers 401 is removed (i.e. the hydraulic cylinder 902 is retracted), and the sliding seat 14 (the turning plate 16) is driven by the driving source to move from the blocking plate to the direction of the filtering monomers 401, referring to fig. 11, a schematic structure that the turning plate 16 passes through the lower part of the supporting arm 11 of the first filtering monomer 401 is shown, a channel is formed between the supporting arm 11 of the filtering monomer 401 and the sliding rail 6, and a head lifting space is formed between the supporting arms 11 of two adjacent filtering monomers 401; when the turning plate 16 passes below the support arm 11 of the first filtering unit 401, the turning plate 16 is pressed down by the support arm 11, so that the turning plate 16 can smoothly pass through the lower part of the first filtering unit 401, when entering the head-up space, the spring 17 is deformed, the raising part 1601 of the turning plate 16 is raised and higher than the height of a channel, as shown in fig. 12, the raising part 1601 is raised after the turning plate 16 enters the head-up space, so that the raising part 1601 can be propped against the support arm 11 when the turning plate 16 returns, the filtering unit 401 is pushed to be separated from the whole filtering unit 4, and the whole filtering unit 401 is separated into a block of filtering unit 401 by reciprocating motion.

Further, as shown in fig. 13, when the monomer separation device moves to the right side of the filtering monomer 401 at the end, because the turning plate 16 is not limited by the supporting pressure of the supporting arm 11 at this time, under the action of the deformation force of the spring 17, the turning plate 16 returns to the original position and can support against the right side of the filtering monomer 401 at the end, if the monomer separation device needs to be moved to the initial position of the carrier 1, the turning plate 16 needs to be continuously pressed down to ensure that the turning plate 16 can smoothly pass through the channel to return to the initial position; the invention designs a return device, which has the following specific structure.

As shown in fig. 8, the return device comprises a pin structure 22 positioned on the slide seat 14 and a trigger structure 21 positioned on the slide rail 6, as shown in fig. 9, an insertion space 1602 is formed on the right hinged side of the turning plate 16, the pin structure 22 is arranged on the right side of the insertion space 1602, the pin structure 22 comprises a limit tube 2201 and a locking post 2202, wherein the limit tube 2201 is arranged on the upper surface of the slide seat 14 and on the right side of the turning plate 16, the limit tube 2201 is slidably matched with the cylindrical locking post 2202, the locking post 2202 faces the insertion space 1602 on the right side of the turning plate 16, and when the turning plate 16 turns left and the insertion space 1602 is lifted by a sufficient height, the locking post 2202 can enter the insertion space 1602 to be locked under the force; as shown in fig. 11, when the flap 16 passes through the lower channel of the arm 11, after the flap 16 is turned to the left, the insertion space 1602 of the flap 16 is lifted to a height that does not allow the locking post 2202 to be inserted into the insertion space 1602, and the locking post 2202 will not actively enter into the insertion space 1602 without external force; as shown in fig. 13, the state diagram of the flap 16 on the rightmost side of the filter 4 is shown, at this time, the flap 16 has completed all the separation operations of the filter units 401, and the flap 16 needs to be returned to the initial position, but the tilting portion 1601 of the flap 16 cannot reversely pass through the channel under the support arm 11 under the action of the spring 17, based on which the pin structure 22 and the triggering structure 21 on the slide rail 6 are required to perform the triggering action, which is specifically as follows.

As shown in fig. 13, the trigger structure 21 is L-shaped, and includes a top plate 2101 and a vertical plate 2102, where the top plate 2101 and the vertical plate 2102 together form a pressing groove, when the flap 16 gradually enters the pressing groove from left to right, one side of a pin shaft of the flap 16 first enters the pressing groove, in the entering process, the top plate 2101 above the pressing groove gradually contacts the flap 16 and turns left, in the turning process, the raising portion 1601 of the flap 16 moves down until passing through a channel below the support arm 11, meanwhile, the height of the insertion space 1602 on the right side of the flap 16 satisfies that the locking position post 2202 enters the insertion space 1602, after that, the locking position post 2202 gradually contacts the vertical plate 2102 in the pressing groove, and the vertical plate 2102 pushes the locking position post 2202 into the insertion space 1602 of the flap 16, so as to lock the state of the flap 16 at this time. The locked turning plate 16 can smoothly pass through the channel below the support arm 11 and return to the initial position on the left side of the sliding rail 6.

Considering that when the flap 16 is restored to the initial position, the flap 16 is convenient to continue to be used next time, and the flap 16 and the locking post 2202 need to be separated, the invention further designs a reset structure 23, and the specific scheme is as follows.

Under the drive of the motor, the conveyor belt 24 starts to run, and when the conveyor belt 24 carries the sludge on the conveyor belt 24 to the end, the sludge falls into a packaging bag on one side of the conveyor belt 24 for subsequent recycling of the sludge.

Example 4

The filtering unit 401 simply relies on the pressure generated by the pressurization of the screw pump 5 to filter the sewage, the sewage filtering speed is slower, the invention designs a structure that, referring to fig. 15, an air injection pipe 26 for injecting air flow is branched on the water injection pipe 8, an air source generating device (the air source generating device is a device for generating air as the name implies, for example, the air source can be compressed air, the air source generating device is a compressed air machine correspondingly, the prior art is not repeated here, and the pressure in the filter 4 is increased after the air flow enters the water channel and the clear water pipe 403 in sequence along with the sewage, so that the sewage flow speed is correspondingly increased, especially the sewage speed passing through the filter layer 27 is increased, thereby ensuring that the sewage is separated into sludge and clear water efficiently and quickly, and the working efficiency is greatly improved.
