Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, and in particular to a discharge mechanism for a dewatering machine. Background Technology

[0002] In the process of garbage sorting, in order to separate different types of garbage, the garbage is often first soaked in water. By utilizing the different buoyancy of substances with different densities, floating plastics, cotton wool, etc. are scooped out. Then, the sand, gravel, non-ferrous metals, etc. that sink to the bottom are dehydrated before proceeding to the next step of separation and recycling. However, in the process of dehydrating the soaked sand, gravel, and non-ferrous metals, centrifugal dewatering machines are often used. In order to achieve the dehydration effect, the centrifugal rotation speed is relatively fast. Before the garbage is discharged from the device, it is necessary to first throw the dehydrated garbage onto the inner wall of the dewatering machine to relieve the pressure before it is discharged in a concentrated manner. Because the garbage that has just been thrown out of the centrifuge drum has inertia, it impacts the inner wall of the machine casing, causing severe wear on the inner wall of the machine casing near the discharge end of the centrifuge drum. Utility Model Content

[0003] To address the aforementioned problems, the present invention aims to provide a discharge mechanism for a dewatering machine, which minimizes the abrasive effect of sand and gravel discharged from the centrifuge cylinder on the inner wall of the machine casing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dewatering machine discharge mechanism includes a base, a housing fixed on the base and vertically arranged in the up-down direction, a detachable cover covering the top of the housing, a feed inlet on the cover and vertically arranged in the up-down direction of the housing, a discharge outlet at the bottom of the housing, a screen rotatably disposed inside the housing for separating water from waste, a centrifugal rotating component rotatably disposed inside the housing for driving the waste inside the screen to perform centrifugal motion, a differential motion component disposed inside the housing for driving the screen and the centrifugal rotating component to rotate at different speeds, an anti-wear component disposed on the inner wall of the housing and located below the screen, and a water collection tank fixed inside the housing and surrounding the outer wall of the screen.

[0006] The wear-resistant component includes a sand-supporting ring fixed to the inner wall of the housing and located below the screen, and a sand-gathering plate fixed to the outer edge of the sand-supporting ring.

[0007] More preferably, the centrifugal rotating assembly includes a rotating shaft coaxially arranged with the feed inlet and rotatably disposed within the housing, and a plurality of scrapers arranged circumferentially and fixed to the upper side wall of the rotating shaft.

[0008] Each of the scrapers is fitted into the inner wall of the screen.

[0009] More preferably, the differential motion assembly includes a differential sleeve rotatably sleeved on a rotating shaft, a plurality of extension rods fixed to the upper end of the outer wall of the differential sleeve, a mounting ring sleeved on the differential sleeve and fixedly connected to the inner wall of each extension rod away from the differential sleeve, a differential gearbox fixed in the middle of the housing and used to drive the differential sleeve and the rotating shaft to rotate at different speeds, and a drive motor fixed on the base and connected to the output shaft of the differential gearbox via a belt pulley drive.

[0010] The lower side of the screen is detachably connected to the mounting ring by fastening screws.

[0011] More preferably, the inner wall of the mounting ring is provided with a sand-guiding slope inclined toward the sand-supporting ring.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, after the garbage is centrifuged and dehydrated in the screen, it is separated from the bottom of the screen. Due to inertia, the sand and gravel are thrown onto the sand-collecting ring. The sand-collecting plate restricts the sand and gravel from falling off the sand-collecting ring, causing the sand and gravel on the sand-collecting ring to accumulate continuously. This causes the sand and gravel thrown out of the screen to be thrown onto the sand and gravel pile, resulting in friction between the sand and gravel and reducing the direct friction between the sand and gravel and the inner wall of the machine casing, thus reducing the wear of the inner wall of the machine casing.

[0014] 2. This utility model guides the sand and gravel that has just been thrown out from below the screen through the sand-guiding inclined surface, so that the sand and gravel thrown out from below the screen are guided to the sand and gravel pile accumulated by the sand-supporting ring.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, a dewatering machine discharge mechanism of this embodiment includes a base 1, a housing 2 fixed on the base 1 and vertically arranged in the up-down direction, a cover 3 detachably covered above the housing 2, a feed inlet 4 arranged on the cover 3 and vertically arranged in the up-down direction of the housing 2, a discharge outlet 5 located at the lower end of the housing 2, a screen 6 rotatably arranged inside the housing 2 for separating water from the waste, a centrifugal rotating assembly 7 rotatably arranged inside the housing 2 for driving the waste in the screen 6 to perform centrifugal motion, a differential motion assembly 8 arranged inside the housing 2 for driving the screen 6 and the centrifugal rotating assembly 7 to rotate at different speeds, an anti-wear assembly 9 located on the inner wall of the housing 2 and below the screen 6, and a water collection tank 10 fixed inside the housing 2 and arranged around the outer wall of the screen 6.

[0023] The anti-wear component 9 includes a sand-collecting ring 91 fixed on the inner wall of the housing 2 and located below the screen 6, and a sand-collecting plate 92 fixed on the outer edge of the sand-collecting ring 91.

[0024] When this product is in use, due to the influence of the garbage's own gravity, the garbage continuously slides down in the screen 6 until it slides to the lower opening of the screen 6 and is thrown out from the lower opening of the screen 6. Due to the influence of rotational inertia, some sand particles are thrown to and accumulate on the sand-collecting ring 91. Under the support of the sand-gathering ring 92, the sand particles form a sand pile on the sand-collecting ring 91, so that the sand particles thrown out from the lower end of the screen 6 are directly thrown onto the accumulated sand pile and do not come into contact with the inner wall of the casing 2 for friction.

[0025] like Figure 1 and Figure 3 As shown, the centrifugal rotating assembly 7 includes a rotating shaft 71 coaxially arranged with the feed inlet 4 and rotatably disposed inside the housing 2, and a plurality of scrapers 72 arranged circumferentially and fixed on the upper side wall of the rotating shaft 71.

[0026] Each scraper 72 is fitted to the inner wall of the screen 6.

[0027] When using this product, the waste is poured into the screen 6 through the feed inlet 4. Driven by the rotating scraper 72, the waste is supported by the side wall of the scraper 72 and rotates at high speed in the screen 6. As a result, the waste is affected by centrifugal force and is thrown onto the inner wall of the screen 6, thereby separating the water in the waste from the screen holes of the screen 6.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, the differential motion assembly 8 includes a differential sleeve 81 rotatably sleeved on the rotating shaft 71, several extension rods 82 fixed to the upper end of the outer wall of the differential sleeve 81, a mounting ring 83 sleeved on the differential sleeve 81 and fixedly connected to the inner wall of each extension rod 82 away from the differential sleeve 81, a differential gearbox 84 fixed in the middle of the housing 2 and used to drive the differential sleeve 81 and the rotating shaft 71 to rotate at different speeds, and a drive motor 85 fixed on the base 1 and connected to the output shaft of the differential gearbox 84 via a belt pulley drive.

[0029] The lower side of the screen 6 is detachably connected to the mounting ring 83 via fastening screws 11.

[0030] When using this product, the screen 6 is fixedly connected to the differential sleeve 81 by the fastening screw 11. The drive motor 85 is started to drive the gear set in the differential gear box 84 to rotate, thereby driving the differential sleeve 81 and the rotating shaft 71 to rotate at different speeds. The rotating shaft 71 rotates at high speed, while the differential sleeve 81 drives the screen 6 to rotate slowly.

[0031] like Figure 3 and Figure 4 As shown, the inner wall of the mounting ring 83 is provided with a sand-guiding slope that is inclined toward the sand-guiding ring 91.

[0032] When this product is in use, the sand particles move along the sand guide slope 12 towards the sand support ring 91, thereby minimizing the impact of centrifugally rotating sand particles on the inner wall of the mounting ring 83 and reducing wear on the inner wall of the mounting ring 83.

[0033] The working principle of this device is as follows:

[0034] Step 1: Start the drive motor 85 to drive the gear set in the differential gear box 84 to rotate, thereby driving the differential sleeve 81 and the rotating shaft 71 to rotate at different speeds. The rotating shaft 71 rotates at high speed, while the differential sleeve 81 drives the screen 6 to rotate slowly.

[0035] Step 2: Pour the garbage into the screen 6 through the feed inlet 4, where it comes into contact with the scraper 72. As the scraper 72 rotates at high speed, the garbage is thrown to the inner wall of the screen 6. The water in the garbage in the screen 6 is thrown out through the holes of the screen 6 and onto the inner wall of the cover 3. Under its own gravity, it flows down into the water collection tank 10.

[0036] Step 3: Due to the influence of the garbage's own gravity, the garbage continuously slides down the screen 6 until it slides to the lower opening of the screen 6. Some sand particles, after just leaving the position driven by the scraper 72, are affected by the rotational inertia and move along the sand guide slope 12 to the top of the sand support ring 91 and accumulate on the sand support ring 91. Under the support of the sand gathering ring 92, the sand particles form a sand particle pile on the sand support ring 91, so that the sand particles thrown out from the lower end of the screen 6 are directly thrown onto the accumulated sand particle pile and do not come into contact with the inner wall of the casing 2. Some of the heavier garbage falls directly from the discharge port 5 under the influence of its own gravity.

[0037] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
