Technical Field

[0001] This utility model relates to the field of polycarboxylate mother liquor technology, and in particular to a device for quantitatively adding polycarboxylate mother liquor. Background Technology

[0002] Polycarboxylate superplasticizer is a high-performance water-reducing agent and a cement dispersant used in cement concrete. It is widely used in highway, bridge, dam, tunnel, and high-rise building projects. This product is environmentally friendly, non-flammable, non-explosive, and can be safely transported by train and truck.

[0003] In the production process of polycarboxylate superplasticizer, the mother liquor needs to be premixed. However, the current method of adding polycarboxylate mother liquor mainly involves weighing it manually and then pouring it into mixing equipment. This manual method is time-consuming and labor-intensive, and both work efficiency and production efficiency are affected by manual labor, resulting in low efficiency.

[0004] Therefore, a device for adding polycarboxylate mother liquor that avoids manual quantitative measurement is proposed. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] In this invention, a collection box collects the liquid falling from the middle drain plate, and the weight of the collection box is measured by a pressure sensor at the lower end. Once the weight reaches a set value, the first solenoid valve closes to prevent the liquid from continuing to flow downwards. Then, the second solenoid valve opens, and the water pump works to draw the liquid out of the collection box and discharge it through the outlet pipe. This achieves quantitative output and addition of liquid, avoiding the time-consuming, labor-intensive, and inefficient situation of manual measurement, thus achieving a high work efficiency.

[0019] In this invention, a motor drives a rotating shaft to agitate the liquid inside the storage chamber, preventing sedimentation during storage and thus improving the quality of the liquid. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a quantitative addition device for polycarboxylate mother liquor, including a quantitative tank 1 for measuring polycarboxylate mother liquor inside, avoiding the influence of external factors. A control panel 3 is installed on the outside of the quantitative tank 1 for operators to operate the device and set the weight, making the operation more convenient. A transparent observation window 2 is provided at the storage cavity of the quantitative tank 1 to facilitate observation of the amount of polycarboxylate mother liquor stored in the storage cavity and facilitate replenishment.

[0027] The lower end of the metering chamber 1 is equipped with a funnel-shaped intermediate strainer 10. The funnel shape facilitates downward discharge, and the intermediate strainer 10 divides the interior of the metering chamber 1 into a storage chamber and a collection chamber. This allows for the storage of the original liquid in the storage chamber, avoiding continuous feeding and saving time. A first solenoid valve 11 is installed at the bottom of the intermediate strainer 10 to control the discharge from the storage chamber. The collection chamber contains a collection box 15 with an open top, and the outer side of the collection box 15 is in contact with the inner wall of the metering chamber 1 to facilitate the collection of liquid by allowing the collection box 15 to move. The bottom of the collection box 15 is connected to the metering chamber 1 via a pressure sensor 16, which detects the weight of the collection box 15, allowing for controlled liquid intake and avoiding manual weighing. The top of the metering chamber 1 has an inlet 5 that penetrates the upper end of the storage chamber. This facilitates the input of liquid into the metering tank 1. A suction pipe 7 is provided on one side of the bottom of the metering tank 1, and an installation cavity 4 is provided at the bottom of the metering tank 1. A water pump 6 is installed inside the installation cavity 4. The upper end of the suction pipe 7 passes through the bottom of the metering tank 1 and the collection box 15, and a second solenoid valve 17 is provided at the passage to facilitate the operation of the discharge effect. The water suction end of the water pump 6 is connected to the other side of the suction pipe 7, and the suction pipe 7 is made of plastic material to give it a certain degree of elasticity, so as to avoid minor damage to the suction pipe 7 when the collection box 15 is subjected to downward force. The water outlet end of the water pump 6 is connected to the liquid outlet pipe 9, which passes through one side of the metering tank 1. Under the action of the water pump 6, the weighed liquid inside the collection box 15 is drawn out through the suction pipe 7 and discharged through the liquid outlet pipe 9, thereby realizing the feeding and conveying work. In addition, the bottom surface of the collection box 15 is inclined to facilitate downward discharge and avoid slow liquid discharge.

[0028] Preferably, a motor 12 is installed at the top of the metering chamber 1, and an installation box 8 is fitted on the outside of the motor 12. A rotating shaft 13 is provided inside the storage chamber, and the upper end of the rotating shaft 13 is connected to the metering chamber 1 through a bearing. Several stirring rods 14 are symmetrically arranged on the outside of the rotating shaft 13. When the motor 12 drives the rotating shaft 13 to rotate the stirring rods 14, the liquid stored in the storage chamber is stirred, thereby avoiding liquid sedimentation.

[0029] Working principle: In use, first connect the control panel 3, water pump 6, first solenoid valve 11, motor 12, pressure sensor 16 and second solenoid valve 17 to an external power source. Then, pour the liquid into the storage chamber at the upper end of the metering tank 1 through the feed port 5. The motor 12 drives the rotating shaft 13 to rotate the stirring rod 14 to agitate the liquid in the storage chamber. When adding the liquid in a metered manner, open the first solenoid valve 11 to allow the liquid to enter the collection tank 15 and be collected. Then, under the action of the pressure sensor 16, the collection tank 15 is weighed. After the set value is reached, the first solenoid valve 11 closes and the second solenoid valve 17 opens. Then, the water pump 6 works to draw out the liquid through the suction pipe 7 and discharge it through the liquid outlet pipe 9, thereby realizing the metered feeding operation.
