[0028] Example 1

[0029] The utility model provides a concrete slurry storage tank, comprising a tank body 11, a discharge pipe 12 and a pre-curing box 13, and also comprising a closed plate unit 1 arranged at the opening of the pre-curing box 13 and used to fix the discharge pipe 12, a guide pipe unit 2 arranged in the pre-curing box 13 and slidably connected to the closed plate unit 1 and used to receive the output slurry of the discharge pipe 12, and a driving unit 3 arranged at the upper end of the closed plate unit 1 and used to drive the guide pipe unit 2 to rise and fall.

[0030] It can be understood that the lower end of the tank body 11 is provided with a support leg to support the tank body; the pre-curing box 13 is arranged on the side end of the support leg, and the upper end of the pre-curing box 13 is open; the discharge pipe 12 is connected to the discharge port at the bottom of the tank body 11, and is arranged to be inserted into the pre-curing box 13 at an angle. The advantage of the inclined arrangement of the discharge pipe 12 is that it can avoid the support leg at the bottom of the tank body 11, so that the pre-curing box 13 can be as close to the tank body 11 as possible, thereby reducing the overall footprint of the device.

[0031] In this embodiment, the closed plate unit 1 includes a plate body 101 disposed at the opening of the pre-curing box 13. The plate body 101 can close the opening of the pre-curing box 13 to prevent the slurry from splashing out of the pre-curing box.

[0032] In this embodiment, the material guide tube unit 2 includes an opening 201 arranged on the plate body 101, a material guide tube 202 arranged in the pre-curing box 13 and the tube wall of which is slidably connected to the opening 201, a discharge port 203 arranged at the lower end of the material guide tube 202, a groove 204 arranged at the upper end of the tube wall of the material guide tube 202 close to the discharge tube 12, a telescopic plate 205 arranged in the groove 204, and a material guide slope 206 arranged on the inner tube wall of the material guide tube 202 away from the discharge tube 12 and extending toward the discharge port 203.

[0033] Among them, the end of the guide pipe 202 close to the bottom surface of the pre-curing box 13 is provided with a blocking plate, and the diameter of the guide pipe 202 is larger than the lower end of the inclined discharge pipe 12, so as to ensure that the slurry discharged from the discharge pipe 12 can be input into the guide pipe 202; the groove depth of the groove 204 accounts for 1 / 2 to 2 / 3 of the overall height of the guide pipe 202, and the groove width of the groove 204 is greater than the width of the discharge pipe 12; the telescopic plate 205 refers to a plate that can be compressed under stress, so that the overall length of the telescopic plate 205 is shortened in the vertical direction, so that the guide pipe 202 can be compressed during the ascending process. The telescopic plate 205 at the lower end of the discharge pipe 12 is compressed to avoid the problem that the discharge pipe 12 interferes with the lifting and lowering of the guide pipe 202. The material of the telescopic plate 205 can be selected from any material in the prior art or a structure that realizes a compressed and folded shape; the setting of the guide slope 206 takes into account the problem that the outlet of the discharge pipe 12 is close to the inner tube wall of the guide pipe 202 away from the discharge pipe 12 side, and the slurry is easy to splash onto the inner tube wall, which is not conducive to flowing out from the discharge port 203. Therefore, the additional guide slope 206 is used to guide the slurry to quickly enter the discharge port 203 to reduce the splashing.

[0034] As a further preference of this embodiment, the telescopic plate 205 includes an arc-shaped fixed rod 205a arranged on the bottom surface of the groove 204, two fixed blocks 205b arranged at both ends of the arc-shaped fixed rod 205a, two limiting grooves 205c arranged on the groove walls on both sides of the groove 204 and respectively used to insert the two fixed blocks 205b, an arc-shaped support rod 205d arranged at the notch of the groove 204, and a telescopic support plate 205e arranged between the arc-shaped fixed rod 205a and the arc-shaped support rod 205d and used to close the groove 204.

[0035] Among them, the arc-shaped fixing rod 205 is completely fitted with the bottom surface of the groove 204 after installation; the arc-shaped support rod 205d is slidably connected to the side wall of the groove 204, and in actual application, in order to reduce the resistance between the two, the telescopic plate 205 also includes sliding grooves arranged on the two side walls of the groove 204, and sliders arranged at both ends of the arc-shaped support rod 205d and slidably connected to the sliding grooves, and the sliders are embedded in the sliding grooves to ensure that there is no obvious gap between the telescopic plate as a whole and the groove, thereby preventing slurry from leaking out; the telescopic support plate 205e can preferably be a corrugated plate made of polytetrafluoroethylene, which can be compressed by force and has a smooth material surface that is not easy to adhere to the slurry.

[0036] In this embodiment, the driving unit 3 includes a bracket 301 disposed on the plate body 101, a cylinder 302 disposed on the bracket 301, a lifting plate 303 connected to the cylinder 302, and a connecting rod 304 disposed on the upper end of the tube wall of the material guide tube 202 and connected to the lifting plate 303. It is worth noting that the side end of the lifting plate 303 cannot cover the discharge tube 12 to prevent the discharge tube 12 from affecting the descent of the lifting plate 303.

[0037] The working principle of the concrete slurry storage tank provided in this embodiment is as follows: the closed plate unit 1 is connected to the discharge pipe 12 and the pre-curing box 13 respectively. In the early stage of pouring, the operating cylinder 302 drives the lifting plate 303 to descend to the lowest position, so that the guide pipe 202 is located at the lowest position in the pre-curing box 13, the discharge port of the tank body 11 is opened, and the slurry is input from the discharge pipe 12 into the guide pipe 202, and then output from the guide pipe 202 to the middle of the pre-curing box 13; as the pouring proceeds, the operating cylinder 302 drives the lifting plate 303 to gradually rise so that the discharge port 203 of the guide pipe 202 rises in the pre-curing box 13 as the castable rises, ensuring sufficient pouring and reducing the generation of splashes and bubbles; when the pouring is completed, the discharge port 203 is located at the highest position, flush with the opening 201 or slightly lower than the opening 201, at which time the telescopic plate 205 is compressed to the shortest, and the connection between the pre-curing box 13 and the closed plate unit 1 is released. During the next pouring, the telescopic plate 205 needs to be restored to the maximum height first.

[0038] Compared with the prior art, the concrete slurry storage tank provided in this embodiment has the following advantages: first, it can effectively avoid splashing of slurry during pouring, which is beneficial to improving the pouring quality; second, the setting of the material guide pipe unit can effectively change the discharge position of the discharge pipe, and avoid the slurry from excessively deviating from the middle of the pre-curing box and being input into the box body, which is beneficial to improving the pouring quality; third, the liftable setting of the material guide pipe unit is beneficial to reducing the problems of splashing and bubbles during pouring, which is beneficial to improving the pouring quality.

[0039] Example 2

[0040] This embodiment optimizes the structure of the closed plate unit 1 on the basis of the embodiment 1, in order to improve the stability of the connection between the closed plate unit 1 and the pre-curing box 13. The specific structure is as follows:

[0041] The closed plate unit 1 further includes an extension vertical plate 102 disposed on the periphery of the plate body 101 and connected to the side wall of the pre-curing box 13 , a threaded hole 103 disposed on the extension vertical plate 102 , and a fastening bolt 104 screwed on the threaded hole 103 .

[0042] Furthermore, one of the three side surfaces of the pre-curing box 13 close to the tank body 11 is not provided with the extending vertical plate 102, so that after the connection between the pre-curing box 13 and the closed plate unit 1 is released, the pre-curing box 13 can be translated out from the side where the extending vertical plate 102 is not provided.

[0043] Example 3

[0044] Based on the embodiment 1, the structure of the driving unit 3 is optimized in this embodiment, as follows:

[0045] The driving unit 3 further comprises a connecting hole 305 arranged at the upper end of the tube wall of the material guiding tube 202, an external thread 306 arranged on the circumference of the lower end of the connecting rod 304, and an internal thread ring 307 arranged on the connecting rod 304 and screwed with the external thread 306. Such an arrangement enables the driving unit 3 to be detachably connected to the material guiding tube 202, which is convenient for maintenance and replacement.

[0046] Example 4

[0047] The difference between this embodiment and the embodiment 1 is that the lifting plate 303 is located at the side end of the opening 201 away from the discharge pipe 12, and the driving unit 3 also includes a telescopic support rod 308 arranged at the lower end of the connecting rod 304 and used to connect with the plate body 101. Among them, the telescopic support rod 308 can be any telescopic rod in the prior art that is compressed under force and returns to its original state without external force, so it is not repeated in this embodiment. The purpose of this arrangement in this embodiment is to enhance the stability of the lifting plate 303 when it is lifted and lowered, to avoid shaking and affecting the quality of pouring.

[0048] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
