Description

Technical Field

[0001] This utility model relates to the field of sand and gravel separation equipment, specifically an automatic sand and gravel washing and separation device. Background Technology

[0002] Automatic sand and gravel separation equipment is a type of equipment used in the environmental protection industry to separate sand, gravel, and water. Current automatic sand and gravel separation equipment typically requires a stirring motor to drive an agitator to stir the sand and gravel mixture inside, aiming to tumble and propel the mixture in a specific direction.

[0003] However, if the sand and gravel in the water are large in volume, they tend to sink to the bottom and are not easily stirred and propelled. Existing solutions typically have two approaches: First, using a high-power stirring motor to ensure washing and propulsion efficiency. However, high-power motors require very high energy consumption, and the high-speed rotating stirring paddle is also prone to breakage when in contact with the sand and gravel. Second, a graded separation method is used. The utility model patent with publication number CN119926878A is an early solution proposed by the applicant, which uses multiple interconnected chambers to ensure the fluidity of the sand and gravel. However, the above solutions require large equipment and cannot be adapted to customers with small construction sites. Utility Model Content

[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings, such as... Figure 1 and Figure 5As shown, the automatic sand and gravel washing and separating device includes a receiving chamber 100, which is divided into a first chamber 10 and a second chamber 20. A partition plate 30 is provided between the first chamber 10 and the second chamber 20. A discharge trough 31 is provided on the top of the partition plate 30. A feed trough 200 is provided on the side wall of the receiving chamber 100. A feed inlet 110 is provided at the rear end of the receiving chamber 100, and the feed inlet 110 communicates with the feed trough 200. A first rotating shaft 120 is installed inside the receiving chamber 100. A sand separating device 300 and a first rotary motor 130 connected to a first rotating shaft 120 are installed outside the front end of the receiving chamber 100, extending through the front end and rear end of the receiving chamber 100. The first rotary motor 130 is used to drive the first rotating shaft 120 to rotate within the receiving chamber 100. A stirring mechanism 140, a first material scooping mechanism 150 and a second material scooping mechanism 160 are installed on the first rotating shaft 120. The second material scooping mechanism 160 is located in the second chamber 20, and the first material scooping mechanism 150 and the feed inlet 110 are located in the first chamber 10.

[0023] In the working state of this embodiment, after the mixture of sand and water enters the feed trough 200, it enters the first chamber 10 through the feed inlet 110. Then, the first rotary motor 130 is started to drive the first rotating shaft 120 to rotate, thereby driving the stirring mechanism 140, the first material scooping mechanism 150, and the second material scooping mechanism 160 to rotate synchronously around the first rotating shaft 120. The stirring mechanism 140 drives the mixture of sand and water to move from the first chamber 10 to the second chamber 20. During the movement of the mixture of sand and water, First, the sand and gravel enter the first scooping mechanism 150, which continuously scoops up the sand and gravel and places it into the feeding trough 31. Then, it enters the second chamber 20, where the sand and gravel undergo a first washing. In the second chamber 20, the stirring mechanism 140 continues to rotate and propel the sand and gravel into the second scooping mechanism 160 for a second washing. The second scooping mechanism 160 then sends the sand and gravel into the sand separating device 300. Finally, the sand separating device 300 lifts the sand and gravel upwards, thus separating it from the receiving chamber 100.

[0024] Compared with the prior art, this application utilizes the method of dividing the receiving chamber 100 into a first chamber 10 and a second chamber 20, and respectively setting a first material scooping mechanism 150 and a second material scooping mechanism 160 in the first chamber 10 and the second chamber 20, so that the mud and sand can be tumbled and washed multiple times in the receiving chamber 100, thereby achieving a better tumbling and washing effect.

[0025] Furthermore, based on the above embodiments, such as Figure 2As shown, the stirring mechanism 140 includes several first support rods 141, which are perpendicularly connected to the first rotating shaft 120. A first connecting rod 142 is provided on the side of the first support rod 141 away from the first rotating shaft 120. Several stirring blades 143 are provided on the first connecting rod 142. When the first rotary motor 130 is started to drive the first rotating shaft 120 to rotate, the first support rod 141 drives the first connecting rod 142 to rotate around the first rotating shaft 120, thereby driving the first stirring blades 143 to rotate around the first rotating shaft 120, and thus driving the mixture of sand and water to move from the rear end to the front end of the receiving chamber 100.

[0026] Furthermore, based on the above embodiments, such as Figure 2 As shown, the first material scooping mechanism 150 includes a plurality of second support rods 151 arranged around the first rotating shaft 120. The second support rods 151 are perpendicular to the first rotating shaft 120. A first connecting ring 152 is connected in series between the second support rods 151. A first hopper 153 is fixed between the first connecting rings 152. When the mixture of sand and water enters the first chamber 10 through the feed inlet 110, it moves towards the second chamber 20 through the stirring mechanism 140, thus entering the range of the first scooping mechanism 150. As the first rotary motor 130 drives the first rotating shaft 120 to rotate, the second support rod 151 drives the first connecting ring 152 to rotate around the first rotating shaft 120, thereby driving the first hopper 153 to continuously scoop up the sand and gravel and put it into the second chamber 20. In this process, in addition to the first washing of the sand and gravel, since the first chamber 10 and the second chamber 20 are separated by the partition plate 30, the mud and sand will pass through the buffer of the first chamber 10 before entering the second chamber 20, avoiding a large amount of mud and sand directly impacting the second chamber 20 and causing poor washing effect. This facilitates the stirring mechanism 140 between the first scooping mechanism 150 and the second scooping mechanism to push the mixture of sand and water from the rear end to the front end of the receiving chamber 100.

[0027] Furthermore, based on the above embodiments, such as Figure 2As shown, a receiving trough 170 is installed on the inner side of the front end of the receiving chamber 100. The receiving trough 170 is interconnected with the sand separating device 300. The second material scooping mechanism 160 includes a plurality of third support rods 161 arranged around the first rotating shaft 120. The third support rods 161 are perpendicular to the first rotating shaft 120. A second connecting ring 162 is connected in series between the third support rods 161, and a second hopper 163 is fixed between the second connecting rings 162. When the mixture of sand and water is pushed from the rear end to the front end of the receiving chamber 100, the first rotary motor 130 drives the first rotating shaft 120 to rotate. The third support rods 161 drive the second connecting rings 162 to rotate around the first rotating shaft 120, thereby driving the second hopper 163 to continuously lift and lower the sand into the receiving trough 170 for preliminary drainage. Then, the sand is lifted and separated out of the receiving chamber 100 by the sand separating device 300. The remaining wastewater is discharged from the outlet 190. Preferably, both the second hopper 163 and the receiving tank 170 are provided with a drain trough 163a. ​​This allows the sand and gravel inside the second hopper 163 to be preliminarily drained before being placed into the receiving tank 170 for a second draining, which facilitates the subsequent sand separating device 300 to lift and separate it out of the second chamber 20.

[0028] Furthermore, based on the above embodiments, such as Figure 2 As shown, a baffle 164 is provided on the side of the second material retrieval mechanism 160 away from the sand separating device 300. The baffle 164 is fixed on the third support rod 161. Several material passages 164a are provided on the baffle 164 near the inner wall of the receiving chamber 100. The function of the baffle 164 is to block and reduce the impact of the water flow. Due to the presence of the first material retrieval mechanism 150, the sand and gravel located between the first material retrieval mechanism 150 and the second material retrieval mechanism 160 are in a suspended state. Although this facilitates the advancement of large pieces of sand and gravel, since the position of the second hopper 163 is close to the inner wall of the receiving chamber 100, in order to facilitate the operation of the second material retrieval mechanism 160, it is necessary to slow down the sand and gravel in the mixture of sand and gravel and water, so that it is suspended near the inner wall of the receiving chamber 100, and then enters the working range of the second material retrieval mechanism 160 through the material passages 164a, so that it can be retrieved and placed into the receiving tank 170 later.

[0029] Furthermore, based on the above embodiments, such as Figure 2As shown, a plurality of reamers 142a are provided on the first connecting rod 142. When the first rotary motor 130 is started to drive the first rotating shaft 120 to rotate, the first support rod 141 drives the first connecting rod 142 to rotate around the first rotating shaft 120, thereby driving the reamers 142a to rotate synchronously. This can increase the rotation speed of the water flow in the accommodating chamber 100, thereby achieving a better propulsion and tumbling effect.

[0030] Furthermore, based on the above embodiments, such as Figure 3 As shown, the sand separating device 300 includes a sand separating chamber 310 inclined upward along one side of the receiving trough 170. A second rotating shaft 320 is provided in the sand separating chamber 310. A second rotary motor 330 is connected to the end of the second rotating shaft 320 away from the receiving trough 170. After the second hopper 163 continuously lifts and lowers the sand and gravel into the receiving trough 170 for preliminary drainage, the second rotary motor 330 is started to drive the second rotating shaft 320 to rotate, thereby moving the sand and gravel along the sand separating chamber 310 and discharging the sand and gravel from the end of the sand separating chamber 310.

[0031] Furthermore, based on the above embodiments, such as Figure 4 As shown, the second rotating shaft 320 includes a first shaft body 321 and a second shaft body 322. The first shaft body 321 extends into the receiving chamber 100, and the second shaft body 322 is connected to the second rotary motor 330. The first shaft body 321 and the second shaft body 322 are connected by a connector 323. The connector 323 includes a lifting ring 323a and a rotating body 323b coaxially disposed within the lifting ring 323a. The two ends of the rotating body 323b are detachably connected to the first shaft body 321 and the second shaft body 322, respectively. The lifting ring 323a is suspended in the sand separating chamber 310 by a U-shaped piece 323C. Thus, when the receiving chamber 100 causes corrosion or damage to the second rotating shaft 320, only the first shaft body 321 extending into the receiving chamber 100 needs to be removed from the connector 323 for replacement. It is not necessary to replace the entire second rotating shaft 320, which greatly saves replacement costs and improves replacement efficiency.

[0032] Furthermore, based on the above embodiments, such as Figure 1 As shown, a water inlet pipe 180 is provided at the top of the feed trough 200. The water inlet pipe 180 is used to spray water onto the sand and gravel mixture in the feed trough 200 to keep it fluid.

[0033] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
