Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to an automatic addition device for biological recovery treatment agent in a low-temperature biological drying machine for sludge. Background Technology

[0002] Sludge drying is a key process that uses heat energy to reduce the moisture content of sludge, thereby achieving volume reduction and stabilization. Unlike traditional drying, biological drying generates heat from the decomposition of organic matter within the sludge, originating from the sludge itself and generating heat from the inside out.

[0003] After the sludge is biologically dried at low temperature, its recycling process uses a biological recycling agent, which can be a liquid. The liquid is stored in a container and automatically added using a liquid delivery pipeline and pump.

[0004] In general, the cylinder of the additive device is directly fixed on the frame. When periodically cleaning the residue inside the cylinder, the space is small due to the cylinder being placed on the frame, which makes cleaning inconvenient.

[0005] In view of this, we propose an automatic addition device for biological recycling treatment agent in a sludge low-temperature biological dryer. Utility Model Content

[0006] The purpose of this invention is to provide an automatic addition device for biological recycling treatment agents in a sludge low-temperature biological dryer, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic addition device for biological recovery treatment agent in a sludge low-temperature biological dryer, comprising a cylinder mounted on a frame, a base at the bottom of the frame, and two sides of the base being movably connected to the bottom of the frame via rails.

[0008] The base extends in and out along one direction from the bottom of the frame.

[0009] Preferably, the bottom of the frame and the base that enters the bottom of the frame are fixed by a fixing structure.

[0010] Preferably, the fixing structure includes a stop block and a fixing block. One end of the stop block is rotatably connected to the bottom of the frame via a hinge A. The fixing block is fixed to the outside of the base. An insert block is inserted into the hole of the fixing block. One end of the insert block is inserted into the insertion hole at the end of the stop block. A moving block is fixed to the other end of the insert block. The moving block is connected to the fixing block via a spring.

[0011] Preferably, the base is provided with a limiting structure, which is used to limit the position of the cylinder placed on the base.

[0012] Preferably, the limiting structure includes a semi-limiting ring, which is fixed on the base. Both ends of the semi-limiting ring are rotatably connected to an arc-shaped plate via hinge B. A connecting block is fixedly provided on the outer periphery of the arc-shaped plate. The connecting block is L-shaped, and a bolt is threaded through the transverse section of the connecting block. The distance between the bolt and the outer periphery of the end of the semi-limiting ring is adjustable.

[0013] Preferably, the inner circumference of the semi-limiting ring matches the inner circumference of the two arc-shaped plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting up a frame, base and track, has the advantages of being able to pull the cylinder out from inside the frame, and having more space and making it more convenient to clean the residue inside the cylinder from outside the frame.

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.

[0029] The present invention provides three embodiments.

[0030] Example 1

[0031] Please see Figure 1 , Figure 2 and Figure 4 An automatic dosing device for biological recovery treatment agents in a low-temperature biological drying machine for sludge includes a cylinder 100 mounted on a frame 200. A base 300 is located at the bottom of the frame 200, and the base 300 is movably connected to the bottom of the frame 200 on both sides via rails 400. The frame 200 is equipped with corresponding pipelines and a pump for pumping liquid. The pump pumps liquid into the cylinder 100 for storage, and when adding liquid, it is pumped out from the corresponding pipelines. The base 300 extends and retracts along one direction from the bottom of the frame 200. To clean residue from the cylinder 100, the pipelines connected to the cylinder 100 are disconnected, allowing the base 300 to be pulled out relative to the bottom of the frame 200, thereby removing the cylinder 100 from the frame 200 and cleaning the residue from inside the cylinder 100.

[0032] This utility model, by setting up a frame 200, a base 300 and a track 400, has the advantages of being able to pull the cylinder 100 out from inside the frame 200, and having more space and making it more convenient to clean the residue inside the cylinder 100 from outside the frame 200. It solves the problem of inconvenience when cleaning the residue inside the cylinder 100 because the space is small when the cylinder 100 is placed at the frame 200.

[0033] Example 2

[0034] Please see Figures 2 to 4An automatic addition device for biological recycling treatment agent in a sludge low-temperature biological drying machine, wherein the bottom of the frame 200 and the base 300 entering the bottom of the frame 200 are fixed by a fixing structure 500.

[0035] The fixed structure 500 includes a stop block 501 and a fixing block 503. One end of the stop block 501 is rotatably connected to the bottom of the frame 200 via a hinge A502. The fixing block 503 is fixed to the outside of the base 300. An insert block 504 is inserted into the hole of the fixing block 503. One end of the insert block 504 is inserted into the insertion hole 5011 at the end of the stop block 501. The other end of the insert block 504 is fixed with a moving block 505. The moving block 505 is connected to the fixing block 503 via a spring 506. Both ends of the spring 506 are connected to the moving block 505 and the fixing block 503 respectively. The elastic coefficient of the spring 506 shall be selected and used by the technical personnel of this profession according to the actual situation.

[0036] This utility model, by setting a stop block 501, hinge A502, fixing block 503, insert block 504, moving block 505 and spring 506, has the advantage that after the base 300 is pushed into the bottom of the frame 200, the base 300 can be restricted within the frame 200, thereby stabilizing the cylinder 100.

[0037] Example 3

[0038] Please see Figures 4 to 6 An automatic addition device for biological recycling treatment agent in a sludge low-temperature biological dryer, wherein a limiting structure 600 is provided on the base 300, and the limiting structure 600 is used to limit the cylinder 100 placed on the base 300.

[0039] The limiting structure 600 includes a semi-limiting ring 601, which is fixed to the base 300. Both ends of the semi-limiting ring 601 are rotatably connected to arc-shaped plates 602 via hinges B603. The inner circumference of the semi-limiting ring 601 matches the inner circumference of the two arc-shaped plates 602. A connecting block 604 is fixedly installed on the outer circumference of the arc-shaped plates 602. The connecting block 604 is L-shaped, and a bolt 605 is threaded through its transverse section. The distance between the bolt 605 and the outer circumference of the end of the semi-limiting ring 601 is adjustable.

[0040] After placing the cylinder 100 on the base 300, the two arc-shaped plates 602 and the semi-limiting ring 601 form a notched ring. Tightening the bolt 605 abuts against the outer circumference of the end of the semi-limiting ring 601, keeping the arc-shaped plates 602 in a stable position, thereby positioning the bottom of the cylinder 100. When removing the cylinder 100, remove the base 300 and tighten the bolt 605 in the opposite direction. The bolt 605 will have a certain distance from the outer circumference of the end of the semi-limiting ring 601. Rotate the arc-shaped plates 602 outward until they no longer block the path of the cylinder 100.

[0041] This utility model, by setting a semi-limiting ring 601, an arc plate 602, a hinge B603, a connecting block 604, and a bolt 605, has the advantages of positioning the bottom of the cylinder 100 placed on the base 300 and facilitating the placement or removal of the cylinder 100.

[0042] Working principle: The pump pumps liquid into the cylinder 100 for storage. When adding liquid, it is pumped out from the corresponding pipe. When cleaning the residue in the cylinder 100, disconnect the pipe connected to the cylinder 100, pull the moving block 505, and the insert block 504 will be pulled out. The spring 506 will be further stretched until one end of the insert block 504 leaves the insertion hole 5011. Rotate to open the stop block 501, and then pull out the base 300 by the external towing machine. The cylinder 100 will then move out of the frame 200. Tighten the bolt 605 in the reverse direction. There is a certain distance between the bolt 605 and the outer circumference of the end of the semi-limiting ring 601. Rotate the arc plate 602 outward until the arc plate 602 no longer blocks the path of the cylinder 100. Connect the cylinder 100 to the external hoist and remove the cylinder 100 for cleaning.

[0043] After cleaning the residue from cylinder 100, place cylinder 100 inside the semi-limiting ring 601 on base 300. The two arc-shaped plates 602 form annular gaps with the semi-limiting ring 601. Tighten bolts 605 to press against the outer periphery of the end of the semi-limiting ring 601, keeping the arc-shaped plates 602 in a stable position, thus positioning the bottom of cylinder 100. Then push the base 300 in, thereby pushing cylinder 100 into frame 200, and connect cylinder 100 to the corresponding pipes.

[0044] 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. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
