Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete mixing technology, and in particular to a slurry filtration structure for a mixing plant. Background Technology
[0002] There are two main sources of slurry from concrete mixing plants: First, wastewater from cleaning concrete mixer trucks and mixers. This wastewater is large in volume and high in concentration, generally containing insoluble substances such as sand, gravel, granular compounds, and water-reducing agents, and its solid content is unstable. Second, wastewater from cleaning the production area and from large and medium-sized vehicles entering and leaving the production area. This wastewater has a relatively simple and stable composition. When filtering the slurry, a sand and gravel separator is usually required. The sand and gravel separator, also called a concrete sand and gravel separator or concrete sand and gravel separation slurry recovery equipment, is the core equipment of the concrete recovery system. It is mainly used to clean, separate, and filter the wastewater from cleaning the mixer trucks and the sand and gravel in the residual concrete.
[0003] Existing sand and gravel separators have the following problems: due to the presence of water, the sand discharged from the discharge port is likely to adhere to and accumulate on the discharge port during the discharge process, making it difficult for the sand to be discharged. In severe cases, the discharge port may become blocked, preventing the sand from being discharged. Therefore, the sand blocking the discharge port is usually manually removed. However, since the discharge port is constantly discharging sand, the operator needs to pay close attention to the sand condition at all times and remove the blockage immediately, which increases the labor intensity of the workers and is not conducive to the operation.
[0004] Therefore, there is an urgent need to provide a slurry filtration structure for mixing plants to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a slurry filtration structure for a mixing plant.
[0006] To solve the above-mentioned technical problems, the present invention provides a slurry filtration structure for a mixing plant, including a sand and gravel separator, wherein the surface of the sand and gravel separator is provided with a sand discharge port and a stone discharge port, and further includes:
[0007] A separation motor is fixedly installed on the surface of the sand and gravel separator, a main discharge mechanism is fixedly installed on the surface of the sand and gravel separator, an auxiliary discharge mechanism is fixedly installed on the lower surface of the main discharge mechanism, and a drive mechanism is fixedly installed on the surface of the main discharge mechanism.
[0008] The present invention is further configured such that: a feed inlet is fixedly installed on the upper surface of the sand and gravel separator, and a water outlet is fixedly installed on one side of the sand and gravel separator.
[0009] The above technical solution involves feeding slurry into the sand and gravel separator through the inlet for sand and gravel separation, and then discharging the separated slurry through the outlet for later use.
[0010] The present invention is further configured such that: the main discharge mechanism includes a main discharge channel, the main discharge channel is fixedly installed on the surface of the sand and gravel separator, a scraper is slidably connected to the surface of the main discharge channel, and the scraper is movably fitted with the inner wall and outer wall of the main discharge channel.
[0011] With the above technical solution, the sand and gravel are discharged into the main discharge channel. At this time, the scraper moves to scrape the sand and gravel on the surface of the main discharge channel, thereby increasing the speed of sand and gravel discharge and preventing the sand and gravel from accumulating on the surface of the main discharge channel and affecting the subsequent discharge of sand and gravel.
[0012] The present invention is further configured such that: symmetrical support columns are fixedly installed on both sides of the main discharge channel, guide rods are fixedly installed on the surface of the support columns, the other end of the guide rods is fixedly connected to the surface of the sand and gravel separator, and a discharge port is opened inside the main discharge channel.
[0013] Through the above technical solution, the support column supports the main discharge channel and the auxiliary discharge channel. The guide rod makes the scraper more stable when it moves inside the main discharge channel. The rear end of the main discharge channel is provided with a discharge port. When the scraper moves backward, it pushes the sand and gravel through the discharge port to the auxiliary discharge channel for discharge, thereby improving the efficiency of sand and gravel discharge.
[0014] The present invention is further configured such that: the auxiliary discharge mechanism includes an auxiliary discharge channel, the auxiliary discharge channel is fixedly connected to the surface of the sand and gravel separator and located below the main discharge channel, and the auxiliary discharge channel is fixedly connected between two support columns.
[0015] With the above technical solution, the auxiliary discharge channel is set at an inclination to discharge the sand and gravel falling from the discharge port. The scraper moves back and forth to make the main discharge channel and the auxiliary discharge channel work simultaneously, thereby improving the discharge efficiency of sand and gravel.
[0016] The present invention is further configured such that: the driving mechanism includes two reciprocating brackets, the reciprocating brackets are rotatably connected in the middle between the support column and the sand and gravel separator, and the scraper is threadedly connected to the surface of the reciprocating brackets.
[0017] With the above technical solution, when the reciprocating support rotates, it drives the scraper to move on the surface of the main discharge channel, thereby discharging the sand and gravel.
[0018] The present invention is further configured such that: a drive motor is fixedly connected to one end of the reciprocating bracket, and sprockets are fixedly installed at the other ends of the two reciprocating brackets, with chains meshing on the surfaces of the two sprockets.
[0019] With the above technical solution, when the drive motor starts, one reciprocating bracket rotates. Through the meshing of the chain and two sprockets, the two reciprocating brackets rotate simultaneously, which further enables the scrapers at the sand discharge port and the stone discharge port to work simultaneously, allowing the main discharge channel and the auxiliary discharge channel to discharge sand and gravel at the same time, thus improving work efficiency.
[0020] The beneficial effects of this utility model are as follows:
[0021] This utility model is equipped with a main discharge channel and an auxiliary discharge channel. By moving the scraper forward, the sand and gravel on the surface of the main discharge channel can be pushed out. When the scraper moves backward, the sand and gravel on the surface of the main discharge channel are transported from the discharge port to the auxiliary discharge channel for discharge. The main discharge channel and the auxiliary discharge channel work simultaneously, thereby improving the efficiency of sand and gravel discharge. Through the setting of the drive mechanism, the sand discharge port and the stone discharge port can work simultaneously. Attached Figure Description

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0028] Please see Figures 1-4 This application provides a slurry filtration structure for a mixing plant, including a sand and gravel separator 1, with a sand discharge port 2 and a stone discharge port 3 on the surface of the sand and gravel separator 1.
[0029] like Figure 1As shown, a feed inlet 11 is fixedly installed on the upper surface of the sand and gravel separator 1, and a water outlet 12 is fixedly installed on one side of the sand and gravel separator 1.
[0030] In this embodiment: the slurry is conveyed to the sand and gravel separator 1 through the feed inlet 11 for sand and gravel separation, and the separated slurry is discharged through the outlet 12 for subsequent use.
[0031] A separation motor 4 is fixedly installed on the surface of the sand and gravel separator 1. A main discharge mechanism 5 is fixedly installed on the surface of the sand and gravel separator 1. An auxiliary discharge mechanism 6 is fixedly installed on the lower surface of the main discharge mechanism 5. A drive mechanism 7 is fixedly installed on the surface of the main discharge mechanism 5.
[0032] like Figure 2 As shown, the main discharge mechanism 5 includes a main discharge channel 51, which is fixedly installed on the surface of the sand and gravel separator 1. A scraper 52 is slidably connected to the surface of the main discharge channel 51, and the scraper 52 is in movable contact with the inner and outer walls of the main discharge channel 51.
[0033] In this embodiment: when the sand and gravel are discharged into the main discharge channel 51, the scraper 52 moves to scrape the sand and gravel on the surface of the main discharge channel 51, thereby increasing the speed of sand and gravel discharge and preventing the sand and gravel from accumulating on the surface of the main discharge channel 51 and affecting the subsequent discharge of sand and gravel.
[0034] like Figure 3 As shown, symmetrical support columns 53 are fixedly installed on both sides of the main discharge channel 51. Guide rods 54 are fixedly installed on the surface of the support columns 53. The other end of the guide rods 54 is fixedly connected to the surface of the sand and gravel separator 1. A discharge port 55 is opened inside the main discharge channel 51.
[0035] In this embodiment: the support column 53 supports the main discharge channel 51 and the auxiliary discharge channel 61. The guide rod 54 makes the scraper 52 more stable when it moves inside the main discharge channel 51. The rear end of the main discharge channel 51 is provided with a discharge port 55. When the scraper 52 moves backward, it pushes the sand and gravel through the discharge port 55 to the auxiliary discharge channel 61 for discharge, thereby improving the efficiency of sand and gravel discharge.
[0036] like Figure 2 As shown, the auxiliary discharge mechanism 6 includes an auxiliary discharge channel 61, which is fixedly connected to the surface of the sand and gravel separator 1 and located below the main discharge channel 51. The auxiliary discharge channel 61 is fixedly connected between two support columns 53.
[0037] In this embodiment, the auxiliary discharge channel 61 is set at an inclination to discharge the sand and gravel falling from the discharge port 55. The scraper 52 scrapes back and forth to make the main discharge channel 51 and the auxiliary discharge channel 61 work simultaneously, thereby improving the discharge efficiency of sand and gravel.
[0038] like Figure 4As shown, the drive mechanism 7 includes two reciprocating supports 71, which are rotatably connected between the support column 53 and the sand and gravel separator 1, and the scraper 52 is threadedly connected to the surface of the reciprocating supports 71.
[0039] In this embodiment: when the reciprocating support 71 rotates, it drives the scraper 52 to move on the surface of the main discharge channel 51, thereby discharging the sand and gravel.
[0040] like Figure 4 As shown, a drive motor 72 is fixedly connected to one end of a reciprocating bracket 71, and sprockets 73 are fixedly installed at the other end of the two reciprocating brackets 71. Chains 74 are meshed on the surfaces of the two sprockets 73.
[0041] In this embodiment: when the drive motor 72 starts, one reciprocating bracket 71 rotates. Through the meshing action of the chain 74 and two sprockets 73, the two reciprocating brackets 71 rotate simultaneously, which further enables the scrapers 52 at the sand discharge port 2 and the stone discharge port 3 to work simultaneously, so that the main discharge channel 51 and the auxiliary discharge channel 61 can discharge sand and gravel at the same time, thereby improving work efficiency.
[0042] When this utility model is in use, the drive motor 72 is started, and the two reciprocating brackets 71 rotate simultaneously. The scrapers 52 at the sand discharge port 2 and the stone discharge port 3 move on the surface of the main discharge channel 51. When the scraper 52 moves forward, it discharges the sand and stones from the front end of the main discharge channel 51. When the scraper 52 moves backward, it pushes the sand and stones from the discharge port 55 to the surface of the auxiliary discharge channel 61. The auxiliary discharge channel 61 is set to be inclined, so that the sand and stones are discharged again.
[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
