Description

A concrete mixing station sewage solid-liquid separator

Technical Field

The utility model relates to the technical field of concrete production, in particular to a sewage solid-liquid separator for a concrete mixing station.

Background Art

Concrete mixing plants often produce a large amount of sewage during concrete production. The sewage usually contains concrete and sand and gravel. If it is discharged directly into the sewage recovery pipe, it is very easy to clog the sewage recovery pipe. It requires long-term manual cleaning of the concrete in the sewage recovery pipe. Moreover, it is extremely difficult to clean after the concrete solidifies, which increases the difficulty and cost of cleaning. Therefore, a sewage solid-liquid separator is needed.

Most of the existing sewage solid-liquid separators do not have a cleaning structure for cleaning solids on their sieve plates when performing solid-liquid separation. When used to screen sewage containing concrete, the concrete is very likely to clog the sieve holes of the sieve plate after solidification, resulting in a reduction in the screening effect. In addition, some of the existing solid-liquid separators that can clean the sieve plate are not convenient for filtering sewage during use when cleaning the sieve plate, and the machine needs to be stopped and waited. It is difficult to achieve the effect of filtering and cleaning at the same time, which affects the filtration efficiency of the equipment.

Therefore, we propose a concrete mixing station sewage solid-liquid separator to solve the above problems.

Utility Model Content

In a further embodiment, the width of one end of the inclined guide plate close to the separation box is greater than the width of the other end to form an inverted trapezoidal structure.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model provides a secondary rotating rod which drives the cleaning bar to rotate through the horizontal bar and the support rod, so as to scrape the surface of the solid-liquid separation filter, and then clean the concrete or sand and gravel screened off the surface of the solid-liquid separation filter. Moreover, the solid-liquid separation filter can rotate relative to the separation box. Since the feed hopper and the cleaning bar are located at two opposite sides of the solid-liquid separation filter, the surface of one side of the solid-liquid separation filter can be cleaned by the cleaning bar when passing through the screening. The whole equipment no longer needs to be stopped for cleaning during the solid-liquid separation of sewage, and the effect of cleaning while filtering is achieved, which ensures the screening effect and improves the filtering efficiency at the same time.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-3, a solid-liquid separator for sewage in a concrete mixing station includes a separation box 1. The separation box 1 adopts a cylindrical structure. A feed hopper 2 is connected to the top plate of the separation box 1. The lower port of the feed hopper 2 extends into the interior of the separation box 1. A liquid outlet pipe 15 is connected to the bottom plate of the separation box 1. The bottom plate of the separation box 1 is inclined toward the liquid outlet pipe 15 to facilitate better diversion of the liquid. A main rotating rod 4 is rotatably installed at the internal axis of the separation box 1, and a disc-shaped solid-liquid separation filter 3 is fixed to the periphery of the main rotating rod 4. The outer edge of the solid-liquid separation filter 3 is in contact with the inner edge of the separation box 1, and the lower port of the feed hopper 2 is close to the surface of the solid-liquid separation filter 3, and the lower port of the feed hopper 2 is smaller than the radius of the solid-liquid separation filter 3, so that the liquid discharged from the feed hopper The injected sewage is not easy to spread over a large area on the surface of the solid-liquid separation filter 3, so that the concrete and sand and gravel left by the screening are concentrated on the solid-liquid separation filter 3 as much as possible, which is convenient for later cleaning. A secondary rotating rod 5 parallel to the main rotating rod 4 is rotatably installed on one side of the notch of the outer wall of the separation box 1, and an inclined guide plate 9 is connected below the notch of the outer wall of the separation box 1. A plurality of horizontal bars 6 are evenly distributed on the outer surface of the secondary rotating rod 5, and a cleaning bar 8 is connected below each horizontal bar 6 through a support rod 7. The lower surface of the cleaning bar 8 is in contact with the upper surface of the solid-liquid separation filter 3, so that when the secondary rotating rod 5 rotates, the cleaning bar 8 can scrape off the deposits on the surface of the solid-liquid separation filter 3 and push them onto the inclined guide plate 9, thereby realizing the cleaning of the solid-liquid separation filter 3.

Please refer to Figure 2-3. In order to facilitate the control of the rotation and movement of the solid-liquid separation filter 3, a main rotating rod 4 is arranged near one end of the inner top of the separation box 1 and is coaxially connected with a bevel gear 10, and a motor 12 is also installed on the inner top of the separation box 1. The output shaft of the motor 12 is connected with a bevel gear 2 11, and the bevel gear 2 11 is vertically meshed with the bevel gear 10, and then the motor 12 drives the bevel gear 2 11 to rotate, and the bevel gear 2 11 meshes with the bevel gear 10 for transmission, thereby driving the main rotating rod 4 to rotate, and the main rotating rod 4 drives the solid-liquid separation filter 3 to rotate. Since the feed hopper 2 and the cleaning bar 8 are located on two opposite sides of the solid-liquid separation filter 3, the solid-liquid separation filter 3 is first filtered and screened from the bottom of the feed hopper 2, and then rotates to the side close to the cleaning bar 8, and the surface deposits are cleaned off by the cleaning bar 8, thereby achieving filtering and cleaning.

Please refer to Figures 2-3. In order to save energy, the main rotating rod 4 and the auxiliary rotating rod 5 are arranged to rotate synchronously. A pulley 13 is coaxially connected to the main rotating rod 4 and the auxiliary rotating rod 5. The pulley 13 is rotatably connected to the separation box 1, and a belt 14 is sleeved between the two pulleys 13. The belt 14 transmits synchronous transmission, so that the auxiliary rotating rod 5 can rotate driven by the main rotating rod 4. One motor 12 can drive the two to rotate at the same time, which is beneficial to saving energy.

Please refer to Figure 4. In order to further improve the cleaning effect of the cleaning strip 8 on the surface of the solid-liquid separation filter 3, the length of the cleaning strip 8 is set to be greater than the radius of the solid-liquid separation filter 3, so that the surface of the solid-liquid separation filter 3 can be fully covered during rotation cleaning, thereby improving the adequacy of cleaning. The cleaning strip 8 is composed of a scraper strip 81 and a brush strip 82 connected in parallel to each other, and the cross-section of the scraper strip 81 adopts an inverted L-shaped structure. The brush strip 82 is fixed on the scraper strip 81. When the brush strip 82 rotates, it contacts and rubs with the mesh of the solid-liquid separation filter 3, thereby removing the concrete blocked in the mesh of the solid-liquid separation filter 3, which is beneficial to reducing the problem of mesh blockage.

Please refer to Figures 1-2. In order to improve the collection effect of concrete or sand and gravel, the width of one end of the inclined guide plate 9 close to the separation box 1 is set to be larger than the notch width of the separation box 1, and the two sides of the inclined guide plate 9 are vertically connected with side plates 91, so that when the cleaning bar 8 pushes the concrete or sand and gravel into the inclined guide plate 9, leakage from the side is reduced to prevent it from falling to the ground and polluting the ground, making it difficult to collect, and the width of one end of the inclined guide plate 9 close to the separation box 1 is larger than the width of the other end to form an inverted trapezoidal structure, so that the discharge end of the inclined guide plate 9 is narrower, which is convenient for guiding the material into the concrete collection box or collection bag, so that the screened concrete or sand and gravel can be collected and stored in a centralized manner.
