Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agent production, in particular to a feeding mechanism for water reducing agent. Background Art

[0002] A dosing mechanism for water reducing agent generally refers to a device or system used to accurately feed water reducing agent into concrete mixing. Water reducing agent is a chemical substance used to reduce the amount of cement in concrete without affecting its working performance. The design and function of the dosing mechanism are crucial to ensure that the water reducing agent is evenly dispersed in the concrete to achieve the expected concrete performance and quality.

[0003] When the water reducing agent feeding device in the prior art is used to feed powdered raw materials, the raw material powder is easily damp and agglomerated, and the agglomerated raw materials cannot be evenly dispersed and dissolved during the dissolution process, which will cause the quality of the final product to be uneven. Some parts may contain large pieces of raw materials, while other parts may contain less or incompletely dissolved raw materials, thereby affecting the consistency and stability of the product.

[0004] Therefore, it is necessary to design a feeding mechanism for water reducing agent to solve the above problems. Utility Model Content

[0008] As a preferred technical solution of the utility model, the intermittent blanking component includes a fixed plate, two first openings, a rotating plate and two second openings, the fixed plate is fixed on the fixed frame, the two first openings are both opened on the fixed plate, the rotating plate is placed above the fixed plate, and the two second openings are both opened on the rotating plate.

[0009] As a preferred technical solution of the utility model, the breaking up assembly includes a motor, a rotating shaft and a plurality of stirring rods. The motor is installed on a fixed frame, one end of the rotating shaft is connected to the output shaft of the motor, and the other end is connected to the middle position of the rotating plate, and the plurality of stirring rods are fixed on the rotating shaft.

[0010] As a preferred technical solution of the present invention, the top surface of the fixed plate and the bottom surface of the rotating plate are in contact with each other.

[0011] As a preferred technical solution of the utility model, a plurality of stirring rods are evenly distributed on the rotating shaft.

[0012] As a preferred technical solution of the present utility model, the two first openings are respectively arranged opposite to the two second openings.

[0013] The utility model has the following beneficial effects:

[0014] 1. When the powder is accumulated on the rotating plate, several stirring rods can effectively stir and break up the powder raw materials, which prevents the powder raw materials from agglomerating due to long-term standing, ensures the fluidity and uniformity of the raw materials, and thus improves the dissolution efficiency and uniformity in the subsequent processing process. Due to the uniform feeding and breaking up of the powder raw materials, the consistency of the raw material ratio and mixing quality of each batch of products is ensured, which helps to reduce product quality fluctuations and improve the stability and quality control ability of the final product;

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3A feeding mechanism for a water reducing agent comprises a frame 1, a feed hopper 2 is fixed on the frame 1, a screw feeding device 3 is also installed on the frame 1, a feeding end of the screw feeding device 3 is arranged directly opposite to the feed hopper 2, a fixing frame 4 is fixed on the feed hopper 2, a fixing frame 5 is fixed on the fixing frame 4, and the fixing frame 5 is in a U-shaped structure;

[0022] An intermittent material discharging component is arranged on the fixed frame 4, and the intermittent material discharging component comprises a fixed plate 61, two first openings 62, a rotating plate 63 and two second openings 64. The fixed plate 61 is fixed on the fixed frame 4, and the two first openings 62 are both opened on the fixed plate 61. The rotating plate 63 is placed above the fixed plate 61, and the top surface of the fixed plate 61 and the bottom surface of the rotating plate 63 are mutually fitted. The two second openings 64 are both opened on the rotating plate 63, and the two first openings 62 are respectively arranged opposite to the two second openings 64. When the two second openings 64 coincide with the two first openings 62, the powdered raw materials will fall through the mutually coincident first openings 62 and second openings 64. When the two second openings 64 are misaligned with the two first openings 62, the powdered raw materials will temporarily accumulate on the rotating plate 63. This design realizes the periodic discharging of the powdered raw materials.

[0023] A breaking up assembly is provided on the fixed frame 5, and the breaking up assembly includes a motor 71, a rotating shaft 72 and a plurality of stirring rods 73. The motor 71 is installed on the fixed frame 5, one end of the rotating shaft 72 is connected to the output shaft of the motor 71, and the other end is connected to the middle position of the rotating plate 63, and the plurality of stirring rods 73 are all fixed on the rotating shaft 72, and the plurality of stirring rods 73 are evenly distributed on the rotating shaft 72. When the powdered raw materials are accumulated on the rotating plate 63, the plurality of stirring rods 73 can stir and break up the powdered raw materials, thereby breaking up the agglomerated large pieces of raw materials and avoiding the phenomenon of powder agglomeration.

[0024] The specific working principle of the utility model is as follows:

[0025] When the feeding mechanism for water reducing agent proposed by the utility model is actually used, the staff starts the motor 71. When the motor 71 is running, it can drive the rotating shaft 72 to rotate. When the rotating shaft 72 rotates, it drives the plurality of stirring rods 73 to rotate. When the rotating shaft 72 rotates, it can also drive the rotating plate 63 to rotate. During the rotation of the rotating plate 63, the two second openings 64 will periodically overlap with the two first openings 62. When the two second openings 64 overlap with the two first openings 62, the powdered raw materials will fall through the overlapping first openings 62 and second openings 64. When the two second openings 64 are misaligned with the two first openings 62, the powdered raw materials will temporarily accumulate on the rotating plate 63. This design realizes the periodic feeding of the powdered raw materials. When the powdered raw materials are accumulated on the rotating plate 63, the plurality of stirring rods 73 can stir and break up the powdered raw materials, thereby breaking up the agglomerated large pieces of raw materials and avoiding the phenomenon of powder agglomeration.
