Description

Technical Field

[0001] The utility model relates to the field of concrete processing, in particular to an anti-adhesion feeding device for concrete processing. Background Art

[0002] In the prior art, produced concrete is generally stored in concrete silos so that it can be quickly taken out when needed, thereby improving the efficiency of engineering construction.

[0003] However, when concrete is discharged from the silo, the concrete adheres to the discharge port. When the concrete adhered to the discharge port comes into contact with moisture in the air, a hydration reaction occurs, which not only increases the temperature of the concrete and the vicinity of the discharge port, but after the temperature increases, the hydrated concrete is more likely to solidify to form a concrete layer that occupies the discharge space, reducing the flow rate at the discharge port and causing inaccurate discharge volume. Utility Model Content

[0010] As a preferred technical solution of the utility model, two U-shaped tubes are symmetrically arranged.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0026] Embodiment 1

[0027] A concrete processing anti-adhesion feeding device, according to Figure 1-5 As shown, it includes a processing tank 1 and a support leg 2; a plurality of support legs 2 are fixedly connected to the lower part of the processing tank 1;

[0028] It also includes a discharge pipe 3, a solenoid valve 4 and a cooling unit; the bottom of the processing tank 1 is connected to the discharge pipe 3; the solenoid valve 4 is installed on the discharge pipe 3; the discharge pipe 3 is connected to the cooling unit; the cooling unit is located below the solenoid valve 4; the cooling unit is used to cool the discharge pipe 3 to prevent the concrete remaining on the inner wall of the discharge pipe 3 from solidifying after the solenoid valve 4 is closed, thereby affecting the normal switching operation of the solenoid valve 4.

[0029] The cooling unit includes an annular water bin Ⅰ101 and a conduit 102; an annular cooling bin 3001 is opened on the side wall of the discharge pipe 3; the outer surface of the discharge pipe 3 is fixedly connected to the annular water bin Ⅰ101; the rear part of the annular water bin Ⅰ101 is connected to the conduit 102; the annular water bin Ⅰ101 and the cooling bin 3001 are connected through a plurality of small holes; the annular water bin Ⅰ101 is located below the solenoid valve 4; the lower part of the cooling bin 3001 is connected to a drain pipe.

[0030] Connect the conduit 102 to the water pipe;

[0031] Connect the solenoid valve 4 to the power supply;

[0032] Connect the drain pipe of the cooling chamber 3001 to the water tank;

[0033] First, the concrete raw material powder that has been preliminarily mixed and processed is sent into the processing tank 1. Then, when the concrete powder raw material needs to be discharged, the collecting mechanism is placed under the discharge pipe 3, and the electromagnetic valve 4 is controlled to open. The concrete in the processing tank 1 is discharged to the collecting mechanism through the discharge pipe 3. The concrete that needs to be taken is set, and then the electromagnetic valve 4 is controlled to close, and the discharge pipe 3 stops discharging;

[0034] After the solenoid valve 4 is closed, concrete adheres to the inner surface of the discharge pipe 3. After the concrete comes into contact with the air, there is moisture in the air. The moisture reacts with the concrete to release a large amount of heat and solidify the concrete, resulting in a concrete layer on the inner wall of the discharge pipe 3. The concrete layer will make it easier for the released concrete raw material powder to remain on its surface, further resulting in the thickening of the concrete layer. The discharge space of the extruded discharge pipe 3 seriously affects the production progress of the enterprise. At this time, the tap water switch is controlled, and the tap water enters the annular water tank Ⅰ101 through the conduit 102, and then the tap water enters the cooling tank 3001 through the small hole. The tap water cools the cooling tank 3001, and the cooling tank 3001 also cools the concrete raw material powder on the inner wall of the discharge pipe 3, so that the solidification speed of the concrete is reduced. Then, after closing the shift every day, the concrete on the inner wall of the discharge pipe 3 can be cleaned manually to effectively avoid the situation where the discharge pipe 3 is blocked.

[0035] Second embodiment

[0036] On the basis of the first embodiment, according to Figure 2-5 As shown, it also includes a motor 201, a gear 202, a gear ring 203, a U-shaped tube 206, a slider 207 and a scraper 208; the motor 201 is installed on the outer ring surface of the discharge tube 3; the output shaft of the motor 201 is fixedly connected to the gear 202; the outer ring surface of the discharge tube 3 is rotatably connected to the gear ring 203; the gear ring 203 meshes with the gear 202; two U-shaped tubes 206 are fixedly connected to the lower part of the gear ring 203; an annular guide rail is opened at the bottom of the discharge tube 3, and two sliders 207 are slidably connected to the bottom of the discharge tube 3; each slider 207 is fixedly connected to a U-shaped tube 206; each U-shaped tube 206 is connected to a scraper 208; all scrapers 208 are slidably connected to the inner wall of the discharge tube 3.

[0037] The two U-shaped tubes 206 are symmetrically arranged.

[0038] The side of the scraper 208 in contact with the discharge pipe 3 is coated with a wear-resistant coating.

[0039] Connect the motor 201 to a power source;

[0040] On the basis of the above-mentioned embodiment, it is difficult to manually clean the concrete on the inner wall of the discharge pipe 3, with low efficiency and incomplete cleaning. At this time, the motor 201 is controlled to be started, and the output shaft of the motor 201 rotates, synchronously driving the transmission ring gear 203 of the gear 202 to rotate, and the ring gear 203 drives the two U-shaped tubes 206 and the corresponding parts thereon to rotate, and the two scrapers 208 rotate synchronously along the inner wall of the discharge pipe 3, and the concrete on the inner wall of the discharge pipe 3 is fully scraped off through the side of the scraper 208, and the scraped concrete falls into the collection mechanism to prevent the concrete from adhering to the inner wall of the discharge pipe 3 and affecting the subsequent discharge of concrete by the discharge pipe 3, and fully recover the adhered concrete, reduce the waste of concrete, reduce the production cost of the enterprise, and cut the labor cost of cleaning the discharge pipe 3. The structure is simple and reliable, and the practicability is strong. The continuous rotation of the scraper 208 can also shake off the concrete raw material powder adhered to its own surface.

[0041] The third embodiment

[0042] On the basis of the second embodiment, according to Figure 2-5 As shown, it also includes a water delivery ring 204 and an annular water tank II 205; the water delivery ring 204 is fixedly connected to the upper part of the gear ring 203; the annular water tank II 205 is fixedly connected to the outer ring surface of the discharge pipe 3; the lower part of the annular water tank II 205 is rotatably connected to the water delivery ring 204; the annular water tank II 205 is connected to the cooling tank 3001 through a plurality of small holes; the annular water tank II 205 is located below the annular water tank I 101; the two U-shaped tubes 206 are both hollow tubes; the two U-shaped tubes 206 are connected to the water delivery ring 204 through a connecting pipe, and the connecting pipes all pass through the gear ring 203; the scraper 208 is a hollow tube, and a plurality of water spray holes 20801 are respectively opened on the front wall and the rear wall of the scraper 208, and electric nozzles are arranged in the water spray holes 20801.

[0043] The water spray hole 20801 is obliquely arranged on the scraper 208 , and the water spray hole 20801 is facing the direction of the inner wall of the discharge pipe 3 .

[0044] It also includes a baffle 209; two baffles 209 are fixedly connected to each scraper 208; each baffle 209 is fixed to the scraper 208 on the side away from the inner wall of the discharge pipe 3, and each baffle 209 is in an active state on the side close to the inner wall of the discharge pipe 3.

[0045] The blocking bar 209 is made of rubber.

[0046] Automatically control the water pressure of tap water;

[0047] A waste collection bucket is placed below the discharge pipe 3;

[0048] On the basis of the above embodiment, the problem that needs to be considered is that if the scraper 208 is used to scrape the inner wall of the discharge pipe 3, and the scraper 208 fits tightly against the inner wall of the discharge pipe 3, the scraper 208 is easy to wear during the rotation process. If the scraper 208 does not fit tightly against the inner wall of the discharge pipe 3, there must be a certain gap between the two. Therefore, there will always be a gap between the scraper 208 and the inner wall of the discharge pipe 3. At this time, a thin layer of concrete will still remain on the inner wall of the discharge pipe 3. If this part of the concrete reacts with the moisture in the air and solidifies on the inner wall of the discharge pipe 3, it will not only aggravate the wear of the scraper 208, but also increase the difficulty of cleaning the inner wall of the discharge pipe 3 later.

[0049] At this time, the water in the cooling bin 3001 is transported to the annular water bin II 205 through the small hole, and then the tap water enters the water delivery ring 204, and the water delivery ring 204 then inputs the water into the U-shaped pipe 206 and the scraper 208 through the connecting pipe. The water pressure of the tap water is controlled so that the tap water can be sprayed from the electric nozzle of the scraper 208, and the tap water washes the concrete remaining on the inner wall of the discharge pipe 3, and the washed waste flows into the collection bucket below. After the washing is completed, the scraper 20 is controlled to close. The electric nozzle of the scraper 208 stops spraying water, and then the operator inserts a water-absorbing cylindrical material into the discharge pipe 3 to absorb the water in the discharge pipe 3. Since the tap water in the cooling bin 3001 is used to cool the discharge pipe 3, the tap water in the cooling bin 3001 has a certain temperature. After the tap water in the cooling bin 3001 is used to clean the inner wall of the discharge pipe 3, the tap water remaining on the inner wall of the discharge pipe 3 after the water-absorbing material is used to absorb it is also easier to evaporate.

[0050] When tap water is sprayed out from the inclined hole of the scraper 208, a large amount of water contacts the discharge pipe 3 and splashes, which has a limited flushing effect on the discharge pipe 3. At this time, a rubber baffle 209 is connected to the scraper 208. When tap water is sprayed out from the inclined hole of the scraper 208, the tap water first lifts up the part of the baffle 209 close to the inner wall of the discharge pipe 3, and the baffle 209 bends, so that the part of the baffle 209 close to the inner wall of the discharge pipe 3 is away from the scraper 208. There is a wedge-shaped gap between the baffle 209 and the scraper 208, and the tap water flows along the baffle. 209 flows along the surface close to the scraper 208, and the baffle 209 guides the tap water to the inner wall of the discharge pipe 3, so that the tap water for cleaning the inner wall of the discharge pipe 3 is more concentrated, and the inner wall of the discharge pipe 3 is cleaned more thoroughly. After the flushing is completed, the baffle 209 is restored, and the baffle 209 is re-attached to the scraper 208 to block the water spray hole 20801 on the scraper 208, effectively preventing the concrete from blocking the water spray hole 20801 of the scraper 208 when the scraper 208 roughly scrapes the inner wall of the discharge pipe 3, thereby affecting the subsequent cleaning of the inner wall of the discharge pipe 3.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
