[0002] According to the principle, sludge dewatering process can be divided into three categories: vacuum filtration dewatering, filter press dewatering and centrifugal dewatering. The main equipment forms include belt filter press, plate and frame filter press, centrifugal dewatering machine and screw stack dewatering machine. Among them, the screw stack dewatering machine uses the extrusion principle to generate a strong extrusion force between the rotation of the auger and the screw stack to achieve solid-liquid separation equipment for extrusion dehydration of sludge.

[0003] The existing technology has the following problems:

[0004] During the sludge dewatering process, the muddy water squeezed out of the dewatering section flows downward. After long-term discharge, the openings of the drainage plate will be blocked, resulting in the closure of the drainage channel. The squeezed muddy water will be discharged from the discharge end seat along with the mud cake, affecting the water content of the output mud cake. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0025] like Figure 1-4 As shown, the utility model proposes a sludge dewatering machine for sludge treatment, comprising a dewatering machine 1, wherein a feed end seat 11 for inputting sludge is installed on the upper part of the dewatering machine 1, and a discharge end seat 12 for discharging mud cake is installed on the side wall;

[0026] The auger mechanism includes a driving device 21 provided on one side of the dehydrator 1. An auger shaft 22 is installed at the output end of the driving device 21 and penetrates the inner cavity of the dehydrator 1. The outer portion of the auger shaft 22 is formed with an auger blade 23 with a spiral structure. The tail of the auger shaft 22 cooperates with the shaft bracket 24 at the end of the dehydrator 1.

[0027] The dehydration mechanism includes a support rod 31 arranged in the inner cavity of the dehydrator 1, on which spiral sheets 32 are arranged at intervals, and a water leakage end seat 33 is arranged below the spiral sheets 32, and the water leakage end seat 33 has a built-in water leakage plate 34 with a water leakage hole;

[0028] The cleaning mechanism includes a track 41 symmetrically arranged at the lower part of the leaking end seat 33, a slidable electric slide 42 is installed in the groove of the track 41, a bracket 43 is clamped between the two electric slides 42, and the edge of the bracket 43 is formed with a scraper part 44 attached to the leaking plate 34.

[0029] It should be noted that:

[0030] 1. The inner cavity of the spiral stack 32 is provided with an annular groove, and the edge of the auger blade 23 is attached to the annular groove; when the auger blade 23 rotates with the auger shaft 22, it contacts the spiral stack 32 and generates a strong extrusion force to act on the sludge for extrusion and dehydration.

[0031] 2. A traction plate with a through hole is provided at the corner of the spiral stack 32. The spiral stack 32 slides left and right along the support rod 31 through the traction plate; the spiral stack 32 can be adjusted by sliding along the support rod 31. By controlling the number and spacing of the spiral stack 32, the extrusion force acting on the sludge can be adjusted, thereby controlling the moisture content of the mud cake after treatment.

[0032] In this embodiment, during the sludge treatment process, when the leakage plate 34 is blocked by mud and water, the leakage plate 34 can be cleaned by a cleaning mechanism, and the bracket 43 slides in the track 41 through the electric slide 42, thereby driving the scraper member 44 to scrape off the mud and water attached to the leakage plate 34 during the forward and backward movement, ensuring the unobstructed leakage holes on the leakage plate 34, preventing mud and water from being mistakenly discharged from the discharge end seat 12 along with the mud cake, and ensuring that the moisture content of the discharged mud cake meets the treatment requirements.

[0033] It can be understood that the leakage plate 34 is a movable structure, which moves up and down along the inner cavity of the leakage end seat 33. During the sludge dewatering process, its upper part is attached to the bottom of the dewatering part of the dewatering machine 1, and during the cleaning process, its lower part is attached to the cleaning mechanism.

[0034] In an optional embodiment, the drain plate 34 is controlled to move up and down by a cylinder structure at the edge;

[0035] Alternatively, the water leakage plate 34 can be lifted and lowered by providing a traction groove on the side wall of the water leakage end seat 33 .

[0036] In an optional embodiment, a sprinkler 46 opening toward the drain plate 34 is provided in the middle of the bracket 43. The sprinkler 46 is connected to an external water supply device through a water supply device 45. Cleaning water is sprayed toward the drain plate 34 through the sprinkler 46 to clear out sludge blockages in the inner cavity of the drain plate 34 and ensure the stability of drainage.

[0037] In order to facilitate the collection of discharged sewage, a sewage trough 5 is further provided below the leaking end seat 33 , and a cavity is provided in the sewage trough 5 .

[0038] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
