Description

Technical Field

[0001] This utility model relates to the field of industrial sludge treatment technology, and in particular to a device suitable for the harmless treatment of industrial sludge. Background Technology

[0002] Industrial wastewater refers to wastewater and waste liquid generated during industrial production processes. It contains industrial production materials, intermediate products, by-products, and pollutants generated during production that are lost with the water. Sludge is generated during wastewater treatment. The higher the degree of wastewater treatment, the more sludge residue is generated that needs to be treated. In order to avoid sludge pollution of the environment, sludge treatment equipment is needed to reduce, stabilize, and render harmless the sludge. In the treatment process, a dewatering device (screw press) is used for dewatering. The specific steps are as follows: wet material (sludge) is fed into the machine through the feed port. The rotating screw shaft uses its screw blades to push the material smoothly towards the discharge port, just like a screw conveyor. Water is discharged through the holes of the cylinder. At the discharge port, the pressure regulating device (such as springs or pushers) resists the discharged dry material, creating a certain resistance and increasing the internal pressure. The extruded material is drier. Finally, the dry material is continuously discharged from the machine through the discharge port.

[0003] However, in practical applications, there are still some unresolved problems. The following are some common problems applicable to industrial sludge harmless treatment devices: During the process of the pressure regulating device resisting the sludge discharged from the outlet, the discharged sludge is easy to fall onto the spring as the push plate rotates. It cannot be blocked, which makes it easy for a lot of sludge to accumulate inside the spring, which can easily affect the next pressure regulation. Utility Model Content

The first fixing component 3 is set on the push plate 18, and the second fixing component 4 is set on one side of the adjusting ring 19.

[0038] The shielding component 2 can shield the first spring 191, preventing the discharged sludge from falling onto the spring as the push plate 18 rotates, thus preventing the spring from accumulating too much sludge and ensuring that the spring can function normally during the next pressure adjustment, thereby improving the accuracy and stability of the device's pressure adjustment.

[0039] Specifically, a first slot 23 is provided inside the second ring body 22, one end of the first ring body 21 is inserted into the first slot 23 and slidably connected, an insertion strip 24 is fixedly provided on one side of the inner wall of the first slot 23, and an insertion groove 25 is provided on one side of the first ring body 21, and the insertion strip 24 is inserted into the insertion groove 25.

[0040] One end of the first ring body 21 is inserted into the first slot 23 opened in the second ring body 22 to form a telescopic protective sleeve. At the same time, the insertion strip 24 fixed to the inner wall of one side of the first slot 23 is inserted into the insertion groove 25 opened on one side of the first ring body 21 (the insertion groove 25 and the insertion strip 24 can prevent the first ring body 21 from rotating freely in the first slot 23 of the second ring body 22).

[0041] Specifically, the first ring body 21 includes a first small semi-ring 211 and a second small semi-ring 212. Both ends of the top of the second small semi-ring 212 are fixed with inserts 26. Both ends of the bottom of the first small semi-ring 211 are provided with insert grooves, and the inserts 26 are inserted into the insert grooves.

[0042] Take the second small half ring 212 and the first small half ring 211 to the position of the spiral shaft 17 (the first spring 191 on the spiral shaft 17 is located inside the second small half ring 212 and the first small half ring 211), and insert the inserts 26 at both ends of the top of the second small half ring 212 into the insert slots opened at the bottom of both ends of the first small half ring 211 to complete the assembly of the first ring body 21.

[0043] Specifically, the second ring body 22 includes a first large half ring 221 and a second large half ring 222. The bottom ends of the first large half ring 221 are provided with insertion slots, and the top ends of the second large half ring 222 are fixedly provided with insertion blocks 27, which are inserted into the insertion slots.

[0044] The first large half-ring 221 and the second large half-ring 222 are moved to the position of the spiral shaft 17 (the first spring 191 on the spiral shaft 17 is located inside the first large half-ring 221 and the second large half-ring 222). Then, the inserts 27 at the top two ends of the second large half-ring 222 are inserted into the insert slots at the bottom two ends of the first large half-ring 221 to complete the assembly of the second ring body 22.

[0045] Specifically, the first fixing member 3 includes a first fixing ring 32 and two first wing screws 31. One side of the first fixing ring 32 is fixed to one side of the push plate 18. The second ring body 22 is inserted into the first fixing ring 32. The two first wing screws 31 are threadedly connected to the first fixing ring 32. The first large half ring 221 and the second large half ring 222 are both provided with first insertion holes 33 on the side that are far apart from each other. One end of the first wing screw 31 is inserted into the first insertion hole 33.

[0046] Insert the second ring 22 into the first fixing ring 32, align the first insertion hole 33 with the first wing screw 31, rotate the first wing screw 31 so that one end is inserted into the first insertion hole 33, and fix the second ring 22.

[0047] Specifically, the second fixing component 4 includes a first L-shaped ring 41, a second L-shaped ring 43, and two second wing screws 42. One side of the first L-shaped ring 41 is fixed to one side of the adjusting ring 19. The second L-shaped ring 43 is located inside the first L-shaped ring 41 and is rotatably connected. Both second wing screws 42 are threadedly connected to the second L-shaped ring 43. The first small half-ring 211 and the second small half-ring 212 are provided with second insertion holes 44 on their opposite sides. One end of the second wing screw 42 is inserted into the second insertion hole 44.

[0048] Pull the first ring 21 and insert one end of the first ring 21 into the second L-shaped ring 43. If the second insertion hole 44 is not aligned with the second wing screw 42, the second L-shaped ring 43 can be rotated by hand (the second L-shaped ring 43 rotates inside the first L-shaped ring 41). After the second wing screw 42 is aligned with the second insertion hole 44, rotate the second wing screw 42 so that one end is inserted into the second insertion hole 44 for fixing.

[0049] The first motor 16 and the second motor 63 are existing technologies. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0050] Example 2, refer to Figures 1-10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0051] Specifically, the machine body 1 also includes a first motor 16 fixed to one side of the frame 12. The output end of the first motor 16 passes through one side of the frame 12 and is fixed to one end of the spiral shaft 17. The first spring 191 is located between the push plate 18 and the adjusting ring 19. A limit strip 194 is fixed to one end surface of the spiral shaft 17. A guide groove is provided on the inner wall of the push plate 18. The limit strip 194 is slidably connected to the inner wall of the guide groove. A handle is fixedly provided on the surface of the adjusting ring 19. An internal thread is provided on the inner wall of the adjusting ring 19. An external thread 192 is provided on one end surface of the spiral shaft 17. The adjusting ring 19 is threadedly connected to the spiral shaft 17.

[0052] The output of the first motor 16 drives the screw shaft 17 to rotate, feeding the industrial sludge to be treated into the cylinder 14 through the feed hopper 15. After entering the cylinder 14, the sludge moves along the cylinder 14 towards the discharge port 193 under the action of the rotating screw shaft 17, and is squeezed by the push plate 18. By rotating the adjustment ring 19 with the handle, the internal thread of the inner wall of the adjustment ring 19 engages with the external thread 192 on one end surface of the screw shaft 17, so that the adjustment ring 19 moves on the screw shaft 17, thereby adjusting the distance between the adjustment ring 19 and the push plate 18. During the adjustment process, the first spring 191 is compressed (the first ring body 21 slides in the second ring body 22, blocking the first spring 191), adjusting the pressure between the push plate 18 and the frame 12. The push plate 18 can be guided by the limit strip 194 and the guide groove, making it difficult for it to rotate freely on the screw shaft 17.

[0053] Specifically, a feed hopper 15 is fixedly installed on one end surface of the cylinder 14 and is connected to it. Multiple drainage holes are opened on the surface of the cylinder 14. A water collection hopper 11 is fixed on the surface of the frame 12. A drain pipe is fixedly installed at the bottom end of the water collection hopper 11 and is connected to it.

[0054] Feeding is facilitated by the feed hopper 15. During the movement of sludge, multiple drainage holes on the surface of the cylinder 14 drain water from the sludge. The water flows into the water collection hopper 11 and is then discharged out of the device through the drain pipe.

[0055] Specifically, an inclined plate 51 is fixedly installed on the inner wall of the frame 12, and a feeding plate 5 is provided above the inclined plate 51. A vibration mechanism 6 is provided on the surface of the inclined plate 51. The vibration mechanism 6 includes four second springs 61, a second motor 63, and a cam 65. A hole 62 is opened on the surface of the inclined plate 51. A fixing plate 64 is fixed on the inner wall of the hole 62. One side of the second motor 63 is fixed to one side of the fixing plate 64, and the output end passes through one side of the fixing plate 64 and is fixedly connected to one side of the cam 65. The four second springs 61 are respectively fixed at the four corners of the surface of the inclined plate 51, and the four bottom corners of the feeding plate 5 are respectively fixed to the tops of the four second springs 61.

[0056] Start the second motor 63. The output of the second motor 63 drives the cam 65 to rotate. During the rotation, the cam 65 periodically pushes the feed plate 5. With the elastic action of the four second springs 61, the feed plate 5 vibrates, so that the sludge falling on the feed plate 5 can fall smoothly and reduce the accumulation of sludge on the feed plate 5.

[0057] Specifically, both sides of the feed plate 5 are fixedly provided with a U-shaped frame 71, and the inner wall of the frame 71 is slidably connected with a guide plate 7. The bottom end of the guide plate 7 is fixedly connected to the surface of the inclined plate 51.

[0058] The U-shaped frame 71 fixed on both sides of the feed plate 5 is slidably connected to the guide plate 7 to ensure that the feed plate 5 can move stably up and down during vibration.

[0059] When it is necessary to install the first ring 21 and the second ring 22 of the shielding component 2, the steps for installing the second ring 22 are as follows: First, take the first large half ring 221 and the second large half ring 222 to the position of the spiral shaft 17 (the first spring 191 on the spiral shaft 17 is located inside the first large half ring 221 and the second large half ring 222). Then, insert the insert blocks 27 at both ends of the top of the second large half ring 222 into the insert block slots opened at both ends of the bottom of the first large half ring 221 to complete the assembly of the second ring 22. Then, insert the second ring 22 into the first fixing ring 32 and align the first insertion hole 33 with the first wing screw 31. Rotate the first wing screw 31 so that one end is inserted into the first insertion hole 33 to fix the second ring 22.

[0060] The steps for installing the first ring body 21 are as follows: take the second small half ring 212 and the first small half ring 211 to the position of the spiral shaft 17 (the first spring 191 on the spiral shaft 17 is located inside the second small half ring 212 and the first small half ring 211), insert the inserts 26 at both ends of the top of the second small half ring 212 into the insert slots opened at the bottom of both ends of the first small half ring 211, and complete the assembly of the first ring body 21.

[0061] Then, insert one end of the first ring 21 into the first slot 23 opened inside the second ring 22. At the same time, ensure that the insertion strip 24 fixed to the inner wall of one side of the first slot 23 is inserted into the insertion groove 25 opened on one side of the first ring 21 (the insertion groove 25 and the insertion strip 24 prevent the first ring 21 from rotating freely in the first slot 23 of the second ring 22). Then, turn the handle, which drives the adjusting ring 19 to rotate (in the initial state, there is a certain gap between the adjusting ring 19 and the push plate 18 at the rightmost end of the spiral shaft 17, which will not affect the adjustment ring 19). (Installation of the first ring 21 and the second ring 22) is achieved by moving the first ring 21 towards the first ring 21 through the threaded connection of the external thread 192 and the internal thread. At the same time, the first ring 21 is pulled to insert one end of the first ring 21 into the second L-shaped ring 43. If the second insertion hole 44 is not aligned with the second wing screw 42, the second L-shaped ring 43 can be rotated by hand (the second L-shaped ring 43 rotates within the first L-shaped ring 41). After the second wing screw 42 is aligned with the second insertion hole 44, the second wing screw 42 is rotated to insert one end into the second insertion hole 44 for fixation.

[0062] In use, according to the industrial sludge treatment requirements, the adjusting ring 19 is rotated by gripping the handle. The internal thread of the adjusting ring 19 engages with the external thread 192 on one end surface of the screw shaft 17, causing the adjusting ring 19 to move on the screw shaft 17, thereby adjusting the distance between the adjusting ring 19 and the push plate 18. During the adjustment process, the first spring 191 is compressed and the first ring body 21 slides within the second ring body 22, blocking the first spring 191 and adjusting the pressure between the push plate 18 and the frame 12 to adapt to the sludge treatment requirements under different working conditions.

[0063] The first motor 16 is started, and its output drives the screw shaft 17 to rotate, feeding the industrial sludge to be treated into the cylinder 14 through the feed hopper 15. After entering the cylinder 14, the sludge moves along the cylinder 14 towards the discharge port 193 under the action of the rotating screw shaft 17. The sludge is squeezed by the push plate 18. During the movement of the sludge, multiple drainage holes on the surface of the cylinder 14 drain the water from the sludge. The water flows into the water collection hopper 11 and then is discharged out of the device through the drain pipe. The dewatered sludge is discharged from the cylinder 14 through the discharge port 193 and falls onto the feed plate 5. The second motor 63 is started, and its output drives the cam 65 to rotate. During the rotation, the cam 65 periodically pushes the feed plate 5. With the elastic action of the four second springs 61, the feed plate 5 vibrates, allowing the sludge falling onto the feed plate 5 to fall smoothly and reducing the accumulation of sludge on the feed plate 5.

[0064] It should be noted that the first motor 16 and the second motor 63 require an external controller (such as a PLC controller) and an external power supply (such as AC power) for operation. The material specifications of the first spring 191 and the second spring 61 can be selected according to actual needs.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. 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.
