[0002] Sludge treatment is an important part of the chemical and machinery industries. It is mainly to reduce the volume of sludge, reduce treatment costs, and realize the resource utilization of sludge. Sludge concentration is the first step in sludge treatment, which mainly reduces the water content in sludge and increases the solid concentration of sludge.

[0003] Existing sludge concentration and dehydration machines generally remove the water contained in the sludge by pressurized concentration and filtration. Due to the high compression rate of the equipment, after the concentration equipment compresses the sludge for a period of time, sludge impurities will inevitably adhere to the contact surface between the concentration equipment and the sludge, which makes it impossible for the sludge concentration and dehydration equipment to always maintain a high dehydration rate. The water content of the sludge treated by the concentration equipment in the later stage will increase significantly.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Example 1, reference Figure 1~Figure 4 , which is the first embodiment of the present invention, provides a sludge concentrating and dehydrating integrated machine, which can achieve a circulating cleaning treatment effect on the sludge, and includes a frame unit 100, a concentrating unit 200, a cleaning unit 300, and a circulating unit 400.

[0034] The concentration unit 200 includes a circulation concentration component 201 installed on the frame unit 100, a dehydration concentration component 202 installed on the frame unit 100 and drivingly matched with the circulation concentration component 201, the matching start end of the circulation concentration component 201 and the dehydration concentration component 202 is set as a sludge feed port M, and the matching end of the circulation concentration component 201 and the dehydration concentration component 202 is set as a sludge discharge port N. During the working process, the staff puts the sludge to be concentrated and dehydrated into the concentration unit 200 from the sludge feed port M, and the sludge enters between the circulation concentration component 201 and the dehydration concentration component 202, and is squeezed by the circulation concentration component 201 and the dehydration concentration component 202 that cooperate with each other. Since the dehydration concentration component 202 is located below the overall frame unit 100, the water contained in the sludge is squeezed and discharged from the dehydration concentration component 202 under the influence of gravity, and then the dehydrated and concentrated sludge flows out from the sludge discharge port N.

[0035] The cleaning unit 300 includes a water supply component 301 installed on the frame unit 100, and a circulating cleaning component 302 mounted on the water supply component 301 and cooperating with the circulating concentration component 201. The circulating cleaning component 302 is mainly used to clean the circulating concentration component 201, the purpose is to remove the sludge remaining on the surface of the circulating concentration component 201 after the sludge is concentrated and dehydrated, and to return the sludge to the circulation line, while reducing the sludge residue and realizing the circulating concentration and dehydration of the sludge; the circulating cleaning component 302 mounted on the water supply component 301 and cooperating with the dehydration component 201 is mainly used to clean the circulating concentration component 201, the purpose is to remove the sludge remaining on the surface of the circulating concentration component 201 after the sludge is concentrated and dehydrated, and to return the sludge to the circulation line, while reducing the sludge residue and realizing the circulating concentration and dehydration of the sludge; The dehydration and cleaning component 303 cooperates with the concentration component 202 and is used to clean the dehydration and concentration component 202. The dehydration and cleaning component 303 flushes and cleans the sludge remaining on the surface of the dehydration and concentration component 202 to reduce the adhesion of the sludge on the surface of the dehydration and concentration component 202, and can also flush the impurities and sewage on the dehydration and concentration component 202 toward the lower part of the frame unit 100, and discharge the sewage inside the concentration unit 200 and the sewage generated by the sludge concentration and dehydration, thereby realizing the sustainable circulation operation of the overall concentration and dehydration integrated equipment.

[0036] The circulation unit 400 includes a circulation mounting frame 401 which is arranged on the frame unit 100 and is located between the sludge feed port M and the sludge discharge port N, and is on the return stroke of the circulation concentration component 201, a sludge diversion component 402 arranged on the circulation mounting frame 401, a sludge scraping component 403 arranged on the circulation mounting frame 401, a hydrophobic component 404 arranged on the circulation mounting frame 401, and a water collection component 405 arranged on the frame unit 100. The circulation unit 400 is used to remove impurities adhering to the surface of the circulation concentration component 201. The circulation mounting frame 401 is set on the return stroke of the circulation concentration component 201. The hydrophobic component 404 can perform preliminary cleaning of the sewage remaining on the contact surface of the circulation concentration component 201 and the sludge after completing a cycle of concentration and dehydration, and the sludge scraping component 403 can scrape the sludge on the surface of the circulation concentration component 201 along the running direction of the circulation concentration component 201. If there is too much sludge remaining, the sludge diversion component 402 is used to guide and divert the large sludge scraped by the sludge scraping component 403, so as to avoid the sludge of the circulation cleaning from clogging the sludge feed port M of the next cycle. The water collection component 405 centrally discharges the sewage generated by the sludge concentration and dehydration inside the frame unit 100, reducing the cleaning pressure of the staff.

[0037] In summary, during the working process, the staff will put the sludge that needs to be concentrated and dehydrated into the concentration unit 200 from the sludge feed port M, and the sludge will enter between the circulation concentration component 201 and the dehydration concentration component 202, and will be squeezed by the circulation concentration component 201 and the dehydration concentration component 202 that cooperate with each other, and then the dehydrated and concentrated sludge will flow out from the sludge discharge port N. The circulation cleaning component 302 is mainly used to clean the circulation concentration component 201, the purpose is to remove the sludge remaining on the surface of the circulation concentration component 201 after the sludge is concentrated and dehydrated, and to return the sludge to the circulation line, while reducing the sludge residue, to achieve the circulation concentration and dehydration of the sludge; the dehydration cleaning component 303 flushes and cleans the sludge remaining on the surface of the dehydration concentration component 202, reduces the adhesion of the sludge on the surface of the dehydration concentration component 202, and achieves the circulation cleaning treatment effect of the sludge, thereby improving the service life and recyclability of the sludge concentration and dehydration machine.

[0038] Example 2, reference Figure 1 to Figure 10, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a concentrating unit 200 and a cleaning unit 300 of a sludge concentrating and dehydrating machine, which solves the problem of decreased dehydration rate of the sludge concentrating and dehydrating machine after long-term operation. It includes a circulating concentrating component 201, including an upper concentrating roller group 201b arranged on the frame unit 100, an upper concentrating belt 201a arranged on the upper concentrating roller group 201b, and an upper tightening part 201c arranged on the frame unit 100 and connected to the upper concentrating roller group 201b.

[0039] Specifically, an upper tightening portion 201c is provided, and the position of the driving roller of the upper concentrating roller group 201b is gradually adjusted by rotating the turntable and the setting of the linear drive structure, thereby adjusting the tension of the upper concentrating belt 201a, so that the sludge concentrating and dehydrating machine can adapt to different sludge processing volumes. When the sludge processing volume is large, the upper concentrating belt 201a and the lower concentrating belt 202a are appropriately loosened to reduce the surface tension of the upper concentrating belt 201a and the lower concentrating belt 202a, thereby leaving space for sludge concentrating. Conversely, when the sludge processing volume is small, the upper concentrating belt 201a and the lower concentrating belt 202a are appropriately tightened to increase the surface tension of the upper concentrating belt 201a and the lower concentrating belt 202a, thereby limiting the concentrating space for the sludge, achieving efficient concentrating of a small amount of sludge, and avoiding the concentrating space for the sludge being too large, resulting in a low compression rate of the sludge and poor dehydration effect.

[0040] The dehydration and concentration assembly 202 includes a lower concentration roller group 202b arranged on the frame unit 100, a lower concentration belt 202a arranged on the lower concentration roller group 202b and matched with the upper concentration belt 201a, and a lower tightening part 202c arranged on the frame unit 100 and connected to the lower concentration roller group 202b.

[0041] Furthermore, an upper discharge roller 201d rotatably connected to the frame unit 100 is provided at one end of the upper concentrating roller group 201b near the sludge discharge port N, and a lower discharge roller 202d rotatably connected to the frame unit 100 is provided at one end of the lower concentrating roller group 202b near the sludge discharge port N, and the upper discharge roller 201d and the lower discharge roller 202d are meshingly connected.

[0042] Furthermore, the water supply assembly 301 includes a main water supply pipe 301b disposed on the frame unit 100, a water supply valve 301a disposed on the main water supply pipe 301b, an upper cleaning pipe 301c disposed on the main water supply pipe 301b, and a lower cleaning pipe 301d disposed on the main water supply pipe 301b. The main water supply pipe 301b is connected to the water supply valve 301a, and can guide the cleaning water entering from the water supply valve 301a. The cleaning water entering the upper cleaning pipe 301c reaches the circulation cleaning assembly 302, and sprays water to clean the circulation concentration assembly 201. Similarly, the cleaning water entering the lower cleaning pipe 301d reaches the dehydration cleaning assembly 303, and sprays water to clean the dehydration cleaning assembly 303.

[0043] Furthermore, the upper cleaning pipe 301c is connected to an upper cleaning nozzle 301c-1 facing the upper concentrating belt 201a; the lower cleaning pipe 301d is connected to a lower cleaning nozzle 301d-1 facing the lower concentrating belt 202a. The upper cleaning pipe 301c supplies water to the upper cleaning nozzle 301c-1, and the upper cleaning nozzle 301c-1 is provided with a water outlet tank with a fluid cross-section smaller than the pipe cross-section that can increase the water flow pressure, thereby providing a high-pressure cleaning water spraying effect to the upper concentrating belt 201a. Similarly, the lower cleaning pipe 301d supplies water to the lower cleaning nozzle 301d-1, and the lower cleaning nozzle 301d-1 is provided with a water outlet tank with a fluid cross-section smaller than the pipe cross-section that can increase the water flow pressure, thereby providing a high-pressure water spraying cleaning effect to the lower concentrating belt 202a.

[0044] Furthermore, the circulation cleaning assembly 302 includes an upper cleaning chamber 302a disposed on the upper cleaning pipe 301c, a concentrated belt guide plate 1 302b disposed on the upper cleaning chamber 302a, and a concentrated belt guide plate 2 302c disposed on the upper cleaning chamber 302a; the concentrated belt guide plate 1 302b is provided with a concentrated belt entry groove 302b-1, and the concentrated belt guide plate 2 302c is provided with a concentrated belt outlet groove 302c-1. The upper concentrated belt 201a passes through the concentrated belt entry groove 302b-1 through the concentrated belt guide plate 1 302b and enters the upper cleaning chamber 302a. When the upper concentrated belt 201a is inside the upper cleaning chamber 302a, the water supply valve 301a starts to supply water, the upper cleaning pipe 301c is filled with water, and the upper cleaning nozzle 301c-1 provides a high-pressure water spray cleaning effect to the upper concentrated belt 201a.

[0045] Furthermore, a rotating groove 302a-1 rotatably connected to the upper cleaning tube 301c is provided on the upper cleaning chamber 302a. The upper cleaning chamber 302a can be rotatably connected relative to the upper cleaning tube 301c under the limit of the rotating groove 302a-1. The upper cleaning chamber 302a can be adaptively deflected in accordance with the transmission direction of the upper concentrating belt 201a that is arranged throughout the upper cleaning chamber 302a. No matter what the tension level or transmission direction of the upper concentrating belt 201a is, the upper cleaning chamber 302a can clean the upper concentrating belt 201a.

[0046] Furthermore, the dehydration cleaning assembly 303 includes a lower cleaning chamber 303a disposed on the lower cleaning pipe 301d, a protective plate 1 303b connected to one end of the lower cleaning chamber 303a and connected to the lower cleaning pipe 301d, and a protective plate 2 303c disposed at the other end of the lower cleaning chamber 303a and connected to the lower cleaning pipe 301d. After the lower concentrating belt 202a is released from the upper concentrating belt 201a, it leaves the dehydration and concentration process and enters the cleaning process below the lower cleaning chamber 303a. The water supply valve 301a starts to supply water, the lower cleaning pipe 301d is filled with water, and the lower cleaning nozzle 301d-1 provides the lower concentrating belt 202a with a high-pressure water spray cleaning effect. At the same time, the high pressure can also promote the water stains generated by the concentration of the sewage remaining on the surface of the lower concentrating belt 202a to be discharged as soon as possible during the transmission process, thereby reducing the sludge and sewage residue on the lower concentrating belt 202a.

[0047] The rest of the structure is the same as that of Example 1.

[0048] In summary, during the working process, the staff will put the sludge that needs to be concentrated and dehydrated into the concentration unit 200 from the sludge feed port M. The sludge enters between the circulation concentration component 201 and the dehydration concentration component 202, and is squeezed by the circulation concentration component 201 and the dehydration concentration component 202 that cooperate with each other. Then, the dehydrated and concentrated sludge flows out from the sludge discharge port N. The circulation cleaning component 302 is mainly used to clean the circulation concentration component 201, with the purpose of removing the sludge remaining on the surface of the circulation concentration component 201 after the sludge is concentrated and dehydrated, and returning the sludge to the circulation line, while reducing the residual sludge and realizing the circulation concentration and dehydration of the sludge; the upper cleaning chamber 302a is provided with a rotating groove 302a-1 that is rotatably connected to the upper cleaning pipe 301c, and the upper cleaning chamber 302a can be rotatably connected relative to the upper cleaning pipe 301c under the limit of the rotating groove 302a-1, and the upper cleaning chamber 302a can be rotatably connected to the upper cleaning pipe 301c under the limit of the rotating groove 302a-1. 02a can be adaptively deflected in coordination with the transmission direction of the upper concentrating belt 201a which is arranged throughout the upper cleaning bin 302a. No matter what the tension level or transmission direction of the upper concentrating belt 201a is, the upper cleaning bin 302a can clean the upper concentrating belt 201a. The dehydration cleaning component 303 flushes and cleans the sludge remaining on the surface of the dehydration and concentrating component 202, thereby reducing the adhesion of the sludge on the surface of the dehydration and concentrating component 202, achieving a circulating cleaning treatment effect on the sludge, and improving the service life and recyclability of the sludge concentrating and dehydrating integrated machine.

[0049] Example 3, reference Figure 1 to Figure 12 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a circulation unit 400 of the sludge thickening and dehydration integrated machine, which solves the problem that the sludge thickening and dehydration integrated machine cannot circulate, concentrate and dehydrate the residual sludge. It includes a sludge diversion component 402, a sludge scraping component 403, a hydrophobic component 404 and a water collection component 405.

[0050] In a specific working process, the upper thickening belt 201 a returning from the sludge discharge port N of the dehydration and thickening process first passes through the hydrophobic component 404 , then reaches the sludge scraping component 403 , and finally reaches the sludge diversion component 402 .

[0051] The hydrophobic assembly 404 includes a hydrophobic mounting frame 404a disposed on the circulation mounting frame 401, and a hydrophobic flow-limiting sheet 404b disposed on the hydrophobic mounting frame 404a.

The scraping side plate 403c and the scraping main board 403d form a "U"-shaped structure facing the sludge discharge port N, and have a certain distance from the upper concentrating belt 201a, leaving a certain residual time for the sludge adhering to the surface of the upper concentrating belt 201a.

The sludge diversion assembly 402 is provided to guide and divert the large sludge scraped off by the sludge scraping assembly 403, so as to prevent the circulating clean sludge from clogging the sludge feed port M of the next circulation. The surface of the diversion plate 402c is provided with an anti-adhesion coating, and is provided with a streamlined material along the flow direction of the upper concentrating belt 201a.

[0054] Furthermore, the water collection component 405 includes a lower water collection bucket 405a installed below the lower concentration belt 202a, a drainage pipe 1 405b arranged at the drainage port of the lower water collection bucket 405a, a concentration drainage bucket 405c arranged below the concentration stroke of the lower concentration belt 202a and the upper concentration belt 201a, a drainage pipe 2 405d arranged on the concentration drainage bucket 405c, a discharge drainage bucket 405e arranged below the discharge stroke of the lower concentration belt 202a and the upper concentration belt 201a, and a drainage pipe 3 405f arranged at the drainage end of the discharge drainage bucket 405e. The water collection component 405 centrally discharges the sewage generated by the sludge concentration and dehydration inside the frame unit 100, reducing the cleaning pressure of the staff.

[0055] The rest of the structure is the same as that of Example 2.

[0056] In summary, during the working process, the staff will put the sludge that needs to be concentrated and dehydrated into the concentration unit 200 from the sludge feed port M, and the sludge will enter between the circulation concentration component 201 and the dehydration concentration component 202, and will be squeezed by the circulation concentration component 201 and the dehydration concentration component 202 that cooperate with each other, and then the dehydrated and concentrated sludge will flow out from the sludge discharge port N. The circulation cleaning component 302 is mainly used to clean the circulation concentration component 201, the purpose is to remove the sludge remaining on the surface of the circulation concentration component 201 after the sludge is concentrated and dehydrated, and to return the sludge to the circulation line, while reducing the sludge residue, to achieve the circulation concentration and dehydration of the sludge; the dehydration cleaning component 303 flushes and cleans the sludge remaining on the surface of the dehydration concentration component 202, reduces the adhesion of the sludge on the surface of the dehydration concentration component 202, and achieves the circulation cleaning treatment effect of the sludge, thereby improving the service life and recyclability of the sludge concentration and dehydration machine. The circulation unit 400 is used to remove impurities adhering to the surface of the circulation concentration component 201. The circulation mounting frame 401 is set on the return stroke of the circulation concentration component 201. The hydrophobic component 404 can perform preliminary cleaning of the sewage remaining on the contact surface of the circulation concentration component 201 and the sludge after completing a cycle of concentration and dehydration, and the sludge scraping component 403 can scrape the sludge on the surface of the circulation concentration component 201 along the running direction of the circulation concentration component 201. If there is too much sludge remaining, the sludge diversion component 402 is used to guide and divert the large sludge scraped by the sludge scraping component 403, so as to avoid the sludge of the circulation cleaning from clogging the sludge feed port M of the next cycle. The water collection component 405 centrally discharges the sewage generated by the sludge concentration and dehydration inside the frame unit 100, reducing the cleaning pressure of the staff.
