Description

Technical Field

[0001] The utility model belongs to the technical field of coating processing, in particular to a feeding component for preparing anti-cracking and waterproof coating. Background Art

[0002] Waterproof coatings are single-component water-based waterproof coatings made with pure acrylic polymer emulsion as the base material and other additives. After curing, waterproof coatings will become a thin film with certain elongation, elasticity, crack resistance, impermeability and weather resistance, which can play a waterproof, anti-seepage and protective role. In the preparation process of waterproof coatings, various ingredients are mixed together to form coatings, and the ingredients of waterproof coatings include various powders and liquid raw materials, and sometimes even some water is needed, so various ingredients are added and mixed in the reactor, but there are the following disadvantages in various feeding operations:

[0003] Since the raw materials of waterproof coatings contain various powders and liquids, and the amount of various ingredients is constant during the mixing process, the amount of ingredients must be guaranteed during the adding process, especially the amount of powders. Therefore, how to add ingredients quantitatively is a problem that needs to be solved.

[0004] Because various powders need to be mixed together for preparation, but after the powders are added, they are usually transported through pipelines and accumulated at a certain discharge point, which can easily lead to agglomeration in subsequent mixing operations, resulting in reduced preparation effect, so the added powders need to be evenly dispersed in the reactor. Utility Model Content

[0005] The utility model aims to provide a feeding component for preparing anti-cracking and waterproof coatings, which solves the problems of being unable to conveniently carry out quantitative feeding, easy accumulation and agglomeration of powder added into a reactor, and lack of uniform distribution of powder by arranging a feeding plate, a feeding hopper, a transfer plate, a feeding channel, a hemispherical distribution tank, and a hollow ring plate.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a feeding component for preparing anti-cracking and waterproof coating, comprising a feeding plate, a transfer plate, a hollow ring plate, a feeding channel and a hemispherical distribution tank, wherein a feeding hopper distributed in a ring array is fixed through the feeding plate, and a motor is arranged at the center below the feeding plate, and the output shaft of the motor is fixedly connected with the center of the feeding plate, the transfer plate is located directly below the feeding plate, a blocking groove is provided on the upper surface of the transfer plate, and a through feeding trough is also arranged in the blocking groove, a feeding channel is fixed in the feeding trough, a hemispherical distribution tank is arranged below the feeding channel, a hollow ring plate is arranged outside the feeding channel, and nozzles distributed in a ring array are fixed at the bottom of the hollow ring plate.

[0008] Furthermore, a protective ring is fixed at the edge of the upper end of the loading plate, and a feeding hopper is also arranged above the loading plate, and the feeding hopper is an inverted hemispherical structure and covers the top of the feeding hopper; the bottom of the motor is fixed at the center of the upper surface of the transfer plate and is located on the inner side of the blocking groove.

[0009] Furthermore, the outer circumference of the hemispherical material distribution tank is penetrated with air holes inclined upward.

[0010] Furthermore, a material pipe is fixed at the bottom of the feeding hopper, and the bottom end of the material pipe contacts the bottom surface of the sealing groove.

[0011] Furthermore, an L-shaped air pipe is fixed through the upper end of the hemispherical material distribution tank, and the vertical section of the air pipe extends upward into the feeding channel, and the horizontal section of the air pipe passes through the outer curved surface of the feeding channel and extends out.

[0012] Furthermore, symmetrically distributed connecting plates are fixed to the bottom of the transfer plate, and the bottom ends of the connecting plates are fixed to the upper end surfaces of the hollow ring plates, and liquid inlet pipes are fixed through the side surfaces of the hollow ring plates.

[0013] Furthermore, the hollow ring plate is distributed outside the feeding channel with the center of the vertical section of the air pipe as the center of the circle.

[0014] The utility model has the following beneficial effects:

[0015] The utility model solves the problem of being unable to carry out quantitative feeding more conveniently by arranging a feeding plate, a feeding hopper, a transfer plate and a feeding channel; powder is added through the feeding hopper, and the powder is continuously added, which may easily cause overflow from the feeding hopper, so when the motor drives the feeding plate to rotate, the feeding hopper rotates accordingly, and the powder exceeding the feeding hopper will be scraped off by the lower end of the feeding hopper, thereby ensuring that only one feeding hopper outputs powder, and when the feeding hopper moves to above the discharge trough of the transfer plate, it stops, and the powder in the feeding hopper will be quantitatively added to the feeding channel and input into containers such as reactors, and the entire process only requires one motor drive, without the need for various conventional weighing-type feedings, which is simpler and more convenient.

[0016] The utility model solves the problems that powder is easily accumulated and agglomerated when added into the reactor, and the powder is not evenly distributed for distribution by arranging a hemispherical distribution tank and a hollow ring plate; when the powder is added into the reactor from the feeding channel, if it is not processed, it is easy to accumulate in large quantities below the feeding channel, resulting in agglomeration during subsequent mixing; therefore, when the powder contacts the hemispherical distribution tank, it is collided and dispersed, and then the compressed air is input through the air pipe and sprayed from the air holes of the hemispherical distribution tank to fully scatter the powder and evenly disperse it in the reactor; at the same time, liquid material is input into the hollow ring plate and sprayed from the nozzle to fully contact the scattered and splashed powder, so that the powder can be quickly mixed and processed, and quickly prepared.

[0027] See also Figure 1-6As shown, the utility model is a feeding component for preparing anti-cracking and waterproof coating, comprising a feeding plate 1, a transfer plate 2, a hollow ring plate 3, a feeding channel 4 and a hemispherical material distributing tank 5, a feeding hopper 101 distributed in a ring array is fixed through the feeding plate 1, and a motor 104 is arranged at the center below the feeding plate 1, and the output shaft of the motor 104 is fixedly connected with the center of the feeding plate 1, the transfer plate 2 is located directly below the feeding plate 1, a blocking groove 202 is opened on the upper surface of the transfer plate 2, and a through feeding trough 203 is also arranged in the blocking groove 202, a feeding channel 4 is fixed in the feeding trough 203, a hemispherical material distributing tank 5 is arranged below the feeding channel 4, a hollow ring plate 3 is arranged outside the feeding channel 4, and nozzles 302 distributed in a ring array are fixed at the bottom of the hollow ring plate 3;

[0028] The feeding plate 1 and the transfer plate 2 are both placed outside the reactor, the hollow ring plate 3, the feeding channel 4 and the hemispherical distribution tank 5 are all located inside the reactor, the powder to be added enters the feeding hopper 101, and when a sufficient amount of powder is added, the motor 104 works to drive the feeding plate 1 and the feeding hopper 101 to rotate, and the excess powder in the feeding hopper 101 is scraped off by the feeding hopper 103, so as to obtain a quantitative amount of powder, and then moves to the top of the lower feeding trough 203, the powder in the feeding hopper 101 enters the feeding channel 4 through the lower feeding trough 203, and then is distributed and dispersed by the hemispherical distribution tank 5, so that the powder is no longer added in a concentrated manner, and at the same time, the hollow ring plate 3 inputs liquid ingredients, which are sprayed out from the nozzle 302 and contact with the dispersed powder, so as to facilitate rapid mixing and preparation.

[0029] A protective ring 102 is fixed at the edge of the upper end of the feeding plate 1, and a feeding hopper 103 is also arranged above the feeding plate 1, and the feeding hopper 103 is an inverted hemispherical structure and covers the top of the feeding hopper 101; the bottom of the motor 104 is fixed at the center of the upper surface of the transfer plate 2 and is located inside the blocking groove 202;

[0030] The feeding hopper 103 is used to assist in adding the required powder ingredients, which are added into the feeding hopper 101 for use. The motor 104 can drive the loading plate 1 to rotate, and the transfer plate 2 remains in position.

[0031] The outer circumference of the hemispherical material distributing tank 5 is provided with air holes 502 which are inclined upward;

[0032] Compressed air is input into the hemispherical material distributing tank 5 and sprayed out from the air hole 502 obliquely upward to quickly blow away the powder material falling in the feeding channel 4, so as to facilitate rapid mixing processing.

[0033] A material pipe 1011 is fixed at the bottom of the feeding hopper 101, and the bottom end of the material pipe 1011 contacts the inner bottom surface of the blocking groove 202;

[0034] When the material pipe 1011 at the bottom of the feeding hopper 101 contacts the blocking groove 202, it will be closed and no material will be discharged, making it convenient for the feeding hopper 103 to add material to it. When the material pipe 1011 moves along the blocking groove 202 to the lower material trough 203, a passage will be formed, and the powder in the feeding hopper 101 will flow downward from the material pipe 1011 into the feeding channel 4.

[0035] An L-shaped air pipe 501 is fixed through the upper end of the hemispherical material distributing tank 5, and the vertical section of the air pipe 501 extends upward into the feeding channel 4, and the horizontal section of the air pipe 501 passes through the outer arc surface of the feeding channel 4 and extends out;

[0039] The hollow ring plate 3 is distributed outside the feeding channel 4 with the center of the vertical section of the air pipe 501 as the center of the circle; the liquid ingredients sprayed out of the hollow ring plate 3 will be above the powder blown away by the hemispherical distribution tank 5, which is convenient for the two to be quickly combined and quickly prepared and mixed.

[0040] The specific working principle of the utility model is as follows: the feeding hopper 103 adds powder to the feeding hopper 101 for use. When a sufficient amount of powder is added, the motor 104 works to drive the feeding plate 1 and the feeding hopper 101 to rotate, and the excess powder in the feeding hopper 101 is scraped off by the feeding hopper 103, thereby obtaining a certain amount of powder. In this process, when the material pipe 1011 at the bottom of the feeding hopper 101 contacts the blocking groove 202, it will be closed and no material will be discharged. When the material pipe 1011 moves along the blocking groove 202 to the lower material groove 20 3, a passage will be formed, and the powder in the feeding hopper 101 will flow downward from the material pipe 1011 into the feeding channel 4.
