Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dry-mix mortar mixing stations, in particular to an anti-segregation dry sand silo. Background Art
[0002] At present, due to the large height difference of the dry sand storage bin in the dry-mix mortar mixing plant, the sand falls faster. At the same time, dry sand with different particle sizes has different densities. This situation will lead to segregation and stratification, which will have a negative impact on the quality of the final mortar product.
[0003] The Chinese utility model with publication number CN213500064U proposes a dry sand bin anti-segregation device, including a feed pipe and a fixed frame. The feed pipe is arranged on the central axis of the dry sand bin, the top is fixedly connected to the dry sand bin cover plate, the bottom is fixedly connected to the fixed frame, and the bottom is opposite to the discharge port of the dry sand bin; the fixed frame is fixed to the lower vertebral part of the dry sand bin, and the wall of the feed pipe is evenly distributed with discharge holes. The advantages are: dry sand enters the feed pipe in the bin through a bucket elevator or a belt conveyor, and after the outlet of the feed pipe is full of material, the dry sand flows out through the discharge hole of the feed pipe, and the dry sand changes from free fall motion to a piled flow state through mutual friction, thereby achieving the purpose of preventing dry sand from segregating or stratifying.
[0004] However, the above practicality still has shortcomings:
[0005] 1. When the sand inflow rate is small, the sand and gravel slide down directly with almost no friction, causing the sand and gravel to separate and stratify.
[0006] 2. When there are too many discharge holes and the sand flow rate is large, the sand and gravel are discharged from the discharge holes, which makes the sand and gravel still have the problem of segregation and stratification. Utility Model Content
[0007] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an anti-segregation dry sand silo, which solves the above-mentioned problem.
[0008] In order to achieve the above-mentioned purpose, the utility model proposes a dry sand silo tube which can prevent segregation.
[0009] As a further solution of the utility model:
[0010] A segregation-resistant dry sand silo comprises a stacking barrel, the top of which is symmetrically fixedly connected with a feed port, the bottom of which is inclined and fixedly connected with a plurality of feed pipes on the central axis of the stacking barrel, the plurality of feed pipes are fixedly connected to each other, a vibration device is fixedly connected at the joint of the bottom layer of feed pipes, and the bottom of the bottom layer of feed pipes is fixedly connected with a discharge pipe.
[0011] Furthermore, the vibration device is fixedly connected with two symmetrical vibration rods, and a plurality of symmetrical feeding tubes contain the vibration rods.
[0012] Furthermore, the feed pipe includes an inclined tube, the top and bottom of which are respectively fixedly connected with a first protrusion and a second protrusion in opposite horizontal directions. The first protrusion and the second protrusion are both provided with the same threaded holes and are threadedly connected with bolts for combining the inclined tube into a long tube with a continuous inclination angle.
[0013] Furthermore, the diameter of the feed pipe decreases step by step from top to bottom, and anti-blocking openings are provided at different diameters of the feed pipe to prevent the feed pipe from being blocked.
[0014] Furthermore, a stabilizing frame is fixedly connected to the lower end of the inner wall of the cavity of the stacking barrel, and the stabilizing frame is elastically connected to the lower end of the feeding pipe.
[0015] Furthermore, the bottom of the stacking barrel is in an inverted cone shape for easy discharge of materials and is fixedly connected with a discharge port for discharge of materials.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] 1. Through the inclined feeding pipe and discharge pipe, the movement state of the gravel during the sliding process changes from free fall to sliding, and the gravel collides and slows down during the sliding process, which increases the friction between the gravel and reduces the possibility of segregation and stratification of the gravel.
[0018] 2. By adopting a modular design for the feed pipe, the first convex plate and the second convex plate can be easily assembled into a long tube by bolting to adapt to stacking barrels of different lengths, which is convenient for transportation, on-site installation and maintenance.

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] like Figure 1-2 As shown, a segregation-resistant dry sand silo comprises a stacking barrel 1, the top of the stacking barrel 1 is symmetrically fixedly connected with a feed port 3, the bottom of the feed port 3 is inclined and fixedly connected with a plurality of feed pipes 4 on the central axis of the stacking barrel 1, the plurality of feed pipes 4 are fixedly connected to each other, a vibration device 5 is fixedly connected at the joint of the feed pipes 4 on the bottom layer, and a discharge pipe 7 is fixedly connected to the bottom of the feed pipes 4 on the bottom layer.
[0024] The vibration device 5 is fixedly connected with two symmetrical vibration rods 6 , and a plurality of symmetrical feeding tubes 4 contain the vibration rods 6 .
[0025] The feed pipe 4 includes an inclined tube 41, and the top and bottom of the inclined tube 41 are respectively fixedly connected with a first convex plate 42 and a second convex plate 43 in opposite horizontal directions. The first convex plate 42 and the second convex plate 43 are both provided with the same threaded holes and are threadedly connected with bolts 44 for combining the inclined tube 41 into a long tube with a continuous inclined angle.
[0026] The diameter of the feed pipe 7 decreases step by step from top to bottom, and anti-blocking openings 8 for preventing the feed pipe 7 from being blocked are provided at different diameters of the feed pipe 7 .
[0027] A stabilizing frame 9 is fixedly connected to the lower end of the inner wall of the cavity of the stacking barrel 1 , and the stabilizing frame 9 is elastically connected to the lower end of the feeding pipe 7 .
[0028] The bottom of the stacking barrel 1 is in an inverted cone shape for easy discharging of materials and is fixedly connected with a discharging port 2 for discharging of materials.
[0029] Working principle: When in use, according to the width of the stacking barrel 1, the feed port 3 is symmetrically fixedly connected to the two sides of the top of the stacking barrel 1, and then according to the length of the stacking barrel 1, a number of feed pipes 4 are prepared and the first convex plate 42 and the second convex plate 43 are fixedly connected by bolts 44 so that the feed pipes 4 are assembled into a long tube. When the gravel slides into the feed pipe 4 from the feed port 3, the gravel changes from free falling motion to sliding motion due to the inclined feed pipe 4, which increases the friction between the gravel and reduces the probability of segregation and stratification of the gravel.
[0030] When the relatively moving gravels collide, the gravels decelerate and fall into the discharge pipe 7 to perform uniform linear motion. Since the diameter of the discharge pipe 7 decreases step by step from top to bottom, the gravels will fall into the bottom of the stacking barrel 1 by friction, reducing the probability of segregation and stratification of the gravels.
[0031] When the flow rate of gravel entering is too large, the vibration device 5 is started, so that the vibrating rod 6 continuously vibrates the gravel in the feeding pipe 4 and the entire feeding structure, making it difficult for the gravel to be blocked, and the excess gravel will fall from the anti-blocking port 8 into the bottom of the stacking barrel 1;
[0032] The stabilizing frame 9 supports the stability of the material discharging structure;
[0033] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
