Description

Technical Field

[0001] The utility model belongs to the technical field of building material processing, in particular to a quantitative feeding device for lime production. Background Art

[0002] Lime is a general term for quicklime and slaked lime, and its main components are calcium oxide (CaO) and magnesium oxide (MgO). The dissolution of quicklime is an important part of construction mixing, and its process must be effectively controlled during specific construction; the dissolution of quicklime is actually a hydration (H2O) exothermic reaction process of CaO (MgO), and the amount of water added and the speed of water addition must be correctly controlled. At the same time, the amount of lime added also needs to be accurately controlled. However, there are still the following disadvantages in the actual process of lime addition:

[0003] First, when lime is put in, since most of the lime is stored in a large amount in containers such as hoppers and storage tanks, the material is usually discharged from the bottom. In this process, firstly, the discharge amount is difficult to control, and secondly, it is easy to cause blockage, which is inconvenient for the putting operation;

[0004] Secondly, during the delivery process, it is not easy to accurately control the delivery amount of lime because it is in powder form. When it is fed, it is easy to accumulate into irregular shapes, and it is not convenient to weigh and quantify it, making it very inconvenient to deliver it in a quantitative manner. Utility Model Content

[0005] The utility model aims to provide a quantitative dosing device for lime production, which solves the problems of being difficult to evenly take out lime from a storage container and being inconvenient to accurately and quantitatively dosing lime by arranging a collecting tank, a feeding chute, a screw, an arc plate, a scraper bar, a scraper shaft, a dosing cylinder, a support plate and a clamping plate.

The material discharge chute is located between the collecting tank and the delivery tube. The inside of the delivery tube is rotatably connected with a rotating shaft, and support plates distributed in a ring array are fixed on the outer periphery of the rotating shaft.

[0009] Furthermore, a base plate is fixed between the bottom surface of the material discharge chute and the outer arc surface of the arc plate, a screw rod is rotatably connected to the bottom of the base plate, and a second frame is threadedly connected to the lower part of the screw rod.

[0010] Furthermore, a frame 1 is fixed to the bottom of the aggregate tank, and the height of the frame 1 is higher than the height of the frame 2, and the rotation radius of the scraper strip is equal to the internal radius of the aggregate tank.

[0011] Furthermore, a slot is provided at the side opening of the aggregate tank, and inserting strips are fixed on both side surfaces of the arc plate adjacent to its arc surface, and the arc plate is inserted into the slot through the inserting strips.

[0012] Furthermore, the upper portion of the delivery tube is connected through a feed inlet, the lower portion of the delivery tube is connected through a discharge outlet, and the lower end of the discharge channel faces above the feed inlet.

When the lime is exported, it is not exported from the bottom of the collection tank but from the side thereof, and the scraper motor drives the scraper shaft to rotate, thereby driving the scraper bar to rotate, scraping the lime on the surface of the collection tank, and scraping the lime on the lower layer by the scraping teeth, so that the lime on the lower layer can be better obtained, and the scraped lime by the scraper bar after scraping a circle will be guided to the discharge chute for discharge, and as the lime in the collection tank gradually decreases, the scraper bar will descend accordingly, and at the same time, the discharge chute is controlled to descend by the screw to make it consistent with the height of the lime in the collection tank, thereby achieving the effect of evenly exporting materials.

[0030] See also Figure 1-8 As shown, the utility model is a quantitative dosing device for lime production, comprising a collection tank 1, a scraper shaft 2, an arc plate 3, a screw 4 and a dosing cylinder 5, a bracket 102 is fixed on the upper end of the collection tank 1, and a scraper motor 103 is fixed on the upper end of the bracket 102, the output shaft of the scraper motor 103 passes through the bracket 102 downward and is fixed to the scraper shaft 2, symmetrically distributed limit strips 201 are fixed on the outer periphery of the scraper shaft 2, a collar 202 is provided on the outer sleeve of the scraper shaft 2 and the limit strip 201, and a scraper strip 203 is fixed on the outer peripheral surface of the collar 202, and a scraper tooth 2031 is fixed on the bottom end of the scraper strip 203;

[0031] The aggregate tank 1 is used to store lime, and a scraper motor 103 is installed on the upper part of the aggregate tank 1 through a bracket 102. When the scraper motor 103 is working, it drives the scraper shaft 2 to rotate. When the scraper shaft 2 rotates, the setting of the limit bar 201 can drive the collar 202 and the scraper strips 203 on the side thereof to rotate accordingly. After the scraper strips 203 rotate, they cooperate with the scraper teeth 2031 to scrape the lime in the aggregate tank 1, thereby scraping the lime on the upper layer thereof, which is convenient for subsequent discharging and delivery;

[0032] The circumference of the collecting tank 1 is plugged with an arc plate 3, and an inclined material discharge channel 301 is fixed on the top of the arc plate 3. The material discharge channel 301 is located between the collecting tank 1 and the delivery tube 5. The inside of the delivery tube 5 is rotatably connected with a rotating shaft 505, and the outer periphery of the rotating shaft 505 is fixed with support plates 506 distributed in a ring array;

[0033] A base plate 302 is fixed between the bottom surface of the material discharge channel 301 and the outer arc surface of the arc plate 3. The bottom of the base plate 302 is rotatably connected to a screw rod 4, and the lower part of the screw rod 4 is threadedly connected to the frame 2 401;

[0034] The material scraped by the scraper strip 203 is led out from the material discharge chute 301 at an angle and enters the delivery tube 5. The material discharge chute 301 can rotate the screw 4 to make the base plate 302 and the material discharge chute 301 descend, so that the material discharge chute 301 is kept at the same height as the lime in the collecting tank 1, ensuring that the lime on the upper layer can be scraped and guided into the material discharge chute 301 every time.

[0035] Secondly, the rotating shaft 505 and the support plate 506 in the delivery tube 5 form an X shape. When the white ash in the feed port 501 enters, the space between the two uppermost support plates 506 is filled with white ash. When too much white ash accumulates in the feed port 501, the rotating shaft 505 rotates ninety degrees, and the other two support plates 506 are aligned with the feed port 501 to receive the material. After being filled, they rotate ninety degrees again. At this time, the white ash between the first two support plates 506 will be discharged from the discharge port 502, realizing quantitative delivery processing.

[0036] A frame 101 is fixed to the bottom of the aggregate tank 1, and the height of the frame 101 is higher than the height of the frame 2 401. The rotation radius of the scraper strip 203 is equal to the inner radius of the aggregate tank 1.

[0037] The frame 101 is used to support the aggregate tank 1, and the frame 2 401 is used to install the screw 4 and provide the screw 4 with a certain lifting space.

[0038] A slot 104 is provided at the side opening of the aggregate tank 1, and insert strips 303 are fixed on both sides of the arc plate 3 adjacent to its arc surface, and the arc plate 3 is inserted into the slot 104 through the insert strips 303;

[0039] The arc plate 3 is inserted into the slot 104 through the inserting strip 303 so that it will not be horizontally offset and can only be raised and lowered to maintain stability.

[0040] The upper part of the delivery tube 5 is connected with an inlet 501 , the lower part of the delivery tube 5 is connected with an outlet 502 , and the lower end of the discharge chute 301 faces above the inlet 501 ; the lime discharged through the discharge chute 301 enters the delivery tube 5 through the inlet 501 .

[0041] Two card slots 5061 are provided on both side surfaces of the support plate 506, and a card plate 507 is inserted into the card slots 5061 on the same straight line on the opposite surfaces of two adjacent support plates 506; by inserting and locking the card plate 507 into the card slots 5061 at corresponding positions, the amount of material that can be received between the two support plates 506 can be changed, and different amounts of material can be obtained by inserting the card plates 507 at different positions.

[0042] A cover plate 503 is fixed on the front side of the delivery tube 5, and a connecting plate 504 is also fixed on the surrounding side of the delivery tube 5, and the upper end of the connecting plate 504 is fixed to the bottom of the base plate 302; the cover plate 503 is used to close the front end of the delivery tube 5, and the card plate 507 can be placed or removed for use. The connection of the connecting plate 504 can make it rise and fall in height along with the discharge chute 301 and the base plate 302 to make it adaptable.

[0043] The specific working principle of the utility model is as follows: first, the aggregate tank 1 is used to store lime, and a scraper motor 103 is installed on the top of the aggregate tank 1 through a bracket 102. When the scraper motor 103 is working, it drives the scraper shaft 2 to rotate. When the scraper shaft 2 rotates, the lime on the surface of the aggregate tank 1 is scraped, and the lime on the lower layer is scraped by the scraper teeth 2031, so that it can better obtain the lime on the lower layer. After the scraper bar 203 scrapes a circle, the scraped lime will be guided to the discharge chute 301 for discharge. As the lime in the aggregate tank 1 gradually decreases, the scraper bar 203 will drop accordingly, and at the same time, the discharge chute 301 is controlled to drop by rotating the screw 4 to make it consistent with the height of the lime in the aggregate tank 1. During this process, the arc plate 3 is inserted into the slot 104 through the insert bar 303, so that it will not shift horizontally, but will only move with the base plate 302 and the discharge chute 301. The material discharged from the discharge chute 301 enters the delivery tube 5, and the rotating shaft 505 and the support plate 506 in the delivery tube 5 form an X shape. When the lime in the feed port 501 enters, the space between the two uppermost support plates 506 is filled with lime. When too much lime is accumulated in the feed port 501, the rotating shaft 505 rotates ninety degrees, and the other two support plates 506 are aligned with the feed port 501 to receive the material. After being fully received, they rotate ninety degrees again. At this time, the lime between the first two support plates 506 will be discharged from the discharge port 502, realizing quantitative delivery processing, which can ensure that the delivery amount of each material receiving and discharging is certain, and the card plate 507 is inserted and connected in the corresponding position of the card slot 5061 to change the amount of material that can be received between the two support plates 506. The card plates 507 at different positions are inserted to obtain different amounts of material.
