Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete raw material processing, in particular to a sand and stone cleaning device and process for concrete processing. BACKGROUND

[0002] At present, the sand and stone cleaning device in the prior art adopts flow cleaning. In order to improve the cleaning efficiency, a spring, a baffle and a power device are used to press the sand and stone and make it disperse, and the contact area of a unit quantity of sand and stone is increased. However, this method cannot completely clean the sand and stone. On the one hand, the spring + baffle seriously restricts the movement path of the sand and stone, and the sand and stone cannot be quickly dispersed. The whole is still prone to congestion, and it is difficult to clean the sand and stone with a large amount. The cleaning effect needs to be improved. On the other hand, the structure also occupies the internal space of the device, and the impurities cleaned out of the sand and stone are easy to cause the filter screen to be blocked.

[0003] Chinese patent application CN115518942A discloses a sand and stone cleaning device applied to concrete processing, which comprises a cleaning box and a water storage tank. The inner wall of the cleaning box is provided with a water outlet cylinder and an electromagnetic valve. A flow distribution plate is fixedly installed on the top of the inner wall of the cleaning box. The inner wall of the cleaning box is rotatably installed with two groups of support shafts through a sealing shaft. Each group of support shafts has four support shafts. A fixed sleeve is fixedly sleeved on the outer surface of the support shaft. An extrusion cylinder is fixedly sleeved on the outer surface of the fixed sleeve. A protrusion is fixedly connected to the outer surface of the extrusion cylinder. A motor is arranged on the left side of the cleaning box. A gear is fixedly connected to the right end of the outer surface of the support shaft. Two groups of support shafts are drivingly connected through a gear, a transmission column and a transmission belt. An outlet assembly is arranged on the front of the cleaning box. A water suction pipe is fixedly connected in the water storage tank. A water pump is fixedly connected to the top end of the water suction pipe. A feeding pipe is fixedly connected to the right side of the top of the water storage tank. A filter screen is fixedly installed on the inner wall of the cleaning box.

[0004] The above scheme improves the cleaning effect of the sand and stone, but uses a circulating water source to clean the sand and stone, and needs to ensure the cleanliness of the circulating water source. The above scheme does not have a cleaning device for the used water source. Therefore, if the untreated water source is used again for cleaning the sand and stone, the sand and stone cannot be completely cleaned, and the sand and stone may even become dirtier. If a general filter screen is used for filtering, the mud and sand washed out of the sand and stone will quickly block the filter screen, thereby affecting the filtering function of the filter screen. Although there are many cleaning devices for the filter screen in the prior art, if the mud and sand feeding amount cannot be reasonably controlled, the filter device will still be quickly blocked, thereby causing the water supply of the cleaning device to be unable to keep up.

[0049] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0050] Reference Figure 1 , Figure 2 , Figure 6 , Figure 8 and Figure 9 : A sand and stone cleaning device for concrete processing, comprising a shell 1, a filtering device 2, a preliminary treatment device 3 and a cleaning device; the filtering device 2 comprises a rotating shell 21, a first driving device 22, a rotating disc 23, a first rotary driver 24, a positioning monitoring assembly 25 and a discharging device 26; a water tank 11 is arranged on one side of the shell 1, the water tank 11 is of an annular structure, the rotating shell 21 is of a tubular structure, and is arranged rotatably above the water tank 11 along the axis of the water tank 11, the upper opening of the rotating shell 21 is larger than the lower opening thereof, and the side wall of the rotating shell 21 is provided with filter holes; the first driving device 22 is arranged on one side of the rotating shell 21, and is used to drive the rotating shell 21 to rotate; the rotating disc 23 is arranged rotatably at the lower part of the rotating shell 21, and a discharging hole is arranged at a non-circular center position of the rotating disc 23, and the discharging hole will coincide with the lower opening of the rotating shell 21 when the rotating disc 23 rotates; the first rotary driver 24 is arranged at the lower part of the rotating disc 23, the output end of the first rotary driver 24 is fixedly connected with the rotating disc 23, and the first rotary driver 24 is used to drive the rotating disc 23 to rotate; the positioning monitoring assembly 25 is arranged on the rotating disc 23, and is used to monitor the coincidence of the discharging hole with the lower opening of the rotating shell 21; the preliminary treatment device 3 is arranged on one side of the rotating shell 21, and contains mud and sand in the preliminary treatment device 3; the discharging device 26 is arranged in the preliminary treatment device 3, and can control the mud and sand to enter the rotating shell 21; a first controller is arranged on the shell 1, and the positioning monitoring assembly 25 controls the operation of the discharging device 26 through the first controller.

[0051] The cleaning device is arranged on the side of the preliminary treatment device 3 away from the filtering device 2, and the cleaning device washes the sand and gravel and periodically discharges the wastewater mixed with the sand and gravel from the bottom. The discharged wastewater enters the preliminary treatment device 3, and the preliminary treatment device 3 preliminarily filters the wastewater mixed with the sand and gravel. Since the unloading device 26 is arranged on the preliminary treatment device 3, the unloading device 26 can control the unloading of the sand and gravel in the preliminary treatment device 3. When the unloading device 26 is closed, the sand and gravel in the preliminary treatment device 3 is blocked by the unloading device 26 and cannot fall into the rotating shell 21. Since the preliminary treatment device 3 preliminarily dehydrates the sand and gravel, the sand and gravel still contains water. When the unloading device 26 is opened, the sand and gravel falls into the rotating shell 21. Since the first driving device 22 always drives the rotating shell 21 to rotate, the water in the sand and gravel is thrown out after the sand and gravel falls into the rotating shell 21. At this time, the rotating disc 23 at the bottom of the rotating shell 21 seals the bottom of the rotating shell 21, that is, the discharge hole on the rotating disc 23 does not coincide with the lower opening of the rotating shell 21. The first rotating driver 24 drives the rotating disc 23 to slowly rotate. Since the rotating disc 23 is provided with a plurality of discharge holes, each discharge hole coincides with the lower opening of the rotating shell 21 at intervals. The discharge hole passes through the lower opening of the rotating shell 21 at a fixed time. The fixed time can be used by the rotating shell 21 to separate the sand and gravel. The sand and gravel is separated from the water due to the centrifugal force after falling into the rotating shell 21. The water is thrown out by the rotating shell 21. When the discharge hole coincides with the rotating shell 21, the positioning monitoring device is activated, and the unloading device 26 is closed. At this time, the sand and gravel in the preliminary treatment device 3 cannot fall into the rotating shell 21. The sand and gravel in the rotating shell 21 is gradually discharged from the discharge hole below the rotating shell 21 under the action of gravity. If the unloading device 26 is in the opened state at this time, the sand and gravel containing water falls into the rotating shell 21. The sand and gravel is discharged from the discharge hole before the rotating shell 21 dehydrates the sand and gravel in time, which is not convenient for subsequent treatment of the sand and gravel and causes unnecessary waste of water. The treated water falls into the water tank 11. The cleaning device can pump the water out of the water tank 11 to wash the sand and gravel in the cleaning device. The device cannot be blocked too quickly when filtering the sand and gravel, which further ensures the water cleanliness and stable supply of the cleaning equipment.

[0052] Referring to Figure 9 and Figure 10 The positioning monitoring device includes a receiver 251 and a transmitter. The receiver 251 is arranged at the bottom of the rotating disc 23 on the side of the discharge hole. The transmitter is arranged directly below the receiver 251, and the output end of the transmitter points to the receiver 251.

[0053] The receiver 251 rotates with the rotating disc 23, while the transmitter is fixed. When the first rotating driver 24 drives the receiver to rotate, and the falling chute coincides with the lower opening of the rotating shell 21, the signal transmitted by the transmitter is received by the receiver 251, and then the receiver 251 sends the signal to the first controller, which controls the unloading device 26 to close.

[0054] With reference to Figure 6 and Figure 8 : The first driving device 22 comprises a first tooth ring 221, a first gear 222, a second rotating driver 223 and a second gear 224. The first tooth ring 221 is fixedly arranged at the bottom of the rotating shell 21 along the axis of the rotating shell 21. The first gear 222 is rotatably arranged at one side of the first tooth ring 221, and the first tooth ring 221 and the first gear 222 are in meshing engagement with each other. The second gear 224 is rotatably arranged at one side of the first gear 222, and the second gear 224 and the first gear 222 are in meshing engagement with each other. The second rotating driver 223 is arranged at the lower part of the second gear 224, and the output end of the second rotating driver 223 is fixedly connected with the second gear 224.

[0055] The first tooth ring 221, the first gear 222 and the second gear 224 are in non-collinear arrangement, so as to save the placement space. When it is required to drive the rotating shell 21 to rotate, the second rotating driver 223 is started, and the second rotating driver 223 drives the second gear 224 to rotate. Since the first gear 222 is in meshing engagement with the second gear 224 and the first tooth ring 221 respectively, when the second gear 224 rotates, the first gear 222 drives the first tooth ring 221 to rotate, so that the rotating shell 21 fixedly connected with the first tooth ring 221 rotates.

[0056] With reference to Figure 3 and Figure 4 : The unloading device 26 comprises a steering gear 261 and a switch plate 262. The steering gear 261 is arranged at one side of the preliminary treatment device 3. The switch plate 262 is fixedly arranged on the output end of the steering gear 261, and the steering gear 261 is used to drive the switch plate 262 to rotate.

[0057] When the positioning monitoring assembly 25 is activated, the steering gear 261 is started, and the steering gear 261 drives the switch plate 262 to rotate, and then the silt in the preliminary treatment device 3 falls into the rotating shell 21.

[0058] With reference to Figure 2 , Figure 5 and Figure 7The filtering device 2 further comprises a cleaning device 27, which comprises a first air pump 271, a central pipe 272, extension pipes 273, a sliding rod 274 and a scraping plate 275; the first air pump 271 is arranged above the rotating shell 21; the central pipe 272 is arranged inside the rotating shell 21 along the axis of the rotating shell 21 and is in communication with the first air pump 271; the extension pipes 273 are arranged on the central pipe 272 uniformly around the axis of the central pipe 272 and are in communication with the central pipe 272; the sliding rod 274 is arranged inside the extension pipes 273 and can slide along the axis direction of the extension pipes 273; and the scraping plate 275 is arranged on the end of the sliding rod 274 away from the central pipe 272.

[0059] Since the silt has a certain adhesion, in order to ensure that the silt in the rotating shell 21 can be better discharged, when the falling hole is aligned with the rotating shell 21, the first air pump 271 will pump air into the central pipe 272, the sliding rod 274 will be pushed out under the action of the air, and the scraping plate 275 will be in contact with the inner wall of the rotating shell 21. Since the rotating shell 21 is always rotating, the scraping plate 275 will scrape the silt on the rotating shell 21 down. It should be noted that the central pipe 272 is fixed.

[0060] Referring to Figure 2 and Figure 5 The cleaning device 27 further comprises a second air pump 276 and a jet pipe 277; the second air pump 276 is arranged on one side of the first air pump 271; and the jet pipe 277 is arranged vertically outside the rotating shell 21 around the axis of the rotating shell 21 and is in communication with the second air pump 276.

[0061] Since the silt exists only on the inner side of the rotating shell 21, the second air pump 276 will be started, the second air pump 276 will spray air through the jet pipe 277, so that air will flow from the outside of the rotating shell 21 into the inside of the rotating shell 21, so as to blow the silt stuck on the inner wall of the rotating shell 21 down, thereby ensuring the filtering property of the rotating shell 21.

[0062] Referring to Figures 1-3 The preliminary treatment device 3 comprises a second driving device 31, a rotating pipe 32 and a guide plate 33; the rotating pipe 32 is arranged obliquely in the shell 1 on one side of the rotating shell 21, the lower side of the rotating shell 21 is located on the upper part of the rotating shell 21, the rotating pipe 32 can rotate along its axis, a plurality of through holes are formed in the rotating pipe 32 and are used for filtering water in the silt; the second driving device 31 is arranged on one side of the rotating pipe 32 and is used for driving the rotating pipe 32 to rotate; and the guide plate 33 is arranged below the rotating pipe 32 and has the same oblique direction as the rotating pipe 32, and is used for receiving the water separated by the rotating pipe 32 and guiding the water to the water tank 11.

[0063] When the second driving device 31 is started, the rotating pipe 32 will drive the sand to rotate, and since the rotating pipe 32 is arranged to be inclined, the sand will flow to the side of the rotating shell 21 under the action of gravity, and the water separated by the rotating pipe 32 is received by the guide plate 33, and the guide plate 33 guides the water flow into the water tank 11.

[0064] With reference to Figure 2 and Figure 3 The second driving device 31 comprises a third rotary driver 311, a third gear 312 and a second gear ring 313; the third rotary driver 311 is arranged on the side wall of the shell 1; the third gear 312 is fixedly arranged on the output end of the third rotary driver 311; and the second gear ring 313 is fixedly arranged on the end of the rotating pipe 32 away from the water tank 11 along the axis of the rotating pipe 32, and the second gear ring 313 and the third gear 312 are in meshing engagement.

[0065] When the rotating pipe 32 needs to be driven to rotate, the third rotary driver 311 is started, and the third gear 312 will drive the second gear ring 313 to rotate, and since the second gear ring 313 is fixedly connected with the rotating pipe 32, the rotating pipe 32 will be driven to rotate.

[0066] With reference to Figure 1 and Figure 2 The preliminary treatment device 3 further comprises a fan 34; the fan 34 is arranged at the upper portion of the rotating pipe 32, and the output end of the fan 34 is directed towards the rotating pipe 32.

[0067] When the fan 34 is started, the fan 34 will blow the sand adhered to the inner wall of the rotating pipe 32, thereby ensuring the filtering performance of the rotating pipe 32.

[0069] S1, the unloading device 26 is opened, the sand in the preliminary treatment device 3 falls into the rotating shell 21, and the first driving device 22 drives the rotating shell 21 to rotate, and the water in the sand is separated out under the action of centrifugal force;

[0070] S2, at the same time, the first rotary driver 24 drives the rotating disc 23 to rotate, and when the rotating shell 21 separates the sand, the lower discharge hole and the lower opening of the rotating shell 21 do not coincide, and the sand will not fall from the lower discharge hole;

[0071] S3, when the lower discharge hole and the lower opening of the rotating shell 21 coincide, the positioning monitoring assembly 25 is activated, the unloading device 26 is closed, and the separated sand falls from the lower opening of the rotating shell 21;
