Description

Technical Field

[0001] This invention relates to the technical field of cement mortar production, and in particular to production equipment for inorganic lightweight aggregate thermal insulation mortar. Background Technology

[0002] In the field of building insulation materials, inorganic lightweight aggregate insulation mortar has become one of the mainstream materials for building interior and exterior wall insulation projects due to its advantages such as fire resistance, flame retardancy, environmental protection and non-toxicity, and high durability. Its core performance (such as thermal conductivity and compressive strength) directly depends on the uniform dispersion and structural integrity of lightweight aggregates (such as vitrified microspheres) in the mortar system.

[0003] However, existing inorganic lightweight aggregate thermal insulation mortar production lines require the cement, sand, and lightweight aggregate needed for each batch to be weighed separately before all raw materials are simultaneously transported to a mixing device for mixing. This production method has the following drawbacks: Firstly, lightweight aggregates (such as vitrified microspheres) are typically lightweight, fluffy, and have a density much lower than that of cementitious materials. When mixed with heavy materials such as cement and sand, they are prone to stratification and segregation, making it difficult to form a uniform dispersion in the mortar system. This results in large fluctuations in the content of lightweight aggregates in the packaged finished product, making it impossible to accurately match the specified weight ratio in the design formula. Consequently, the thermal insulation performance of the product is unstable, and there are significant differences in quality between batches. Secondly, in order to improve the dispersion effect, it is often necessary to strengthen the mixing intensity by increasing the stirring speed and extending the stirring time, which greatly increases the energy consumption of production; Third, for brittle lightweight aggregates such as vitrified microspheres, the impact and compression during high-intensity mixing and raw material transportation can cause damage to their vitrified outer shell and collapse of their internal porous structure, affecting the thermal insulation performance of the mortar. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing an inorganic lightweight aggregate thermal insulation mortar production equipment and production method that can solve the above problems.

[0005] To achieve the above objectives, this invention proposes an inorganic lightweight aggregate thermal insulation mortar production equipment, comprising a cement silo, a sand silo, a metering silo, a mixing silo, a semi-finished product silo, a lightweight aggregate silo, and several weighing silos. The cement silo is connected to the inlet of the metering silo via a first feeding device. The sand silo is connected to the inlet of the metering silo via a second feeding device. The outlet of the mixing silo is connected to the semi-finished product silo. The semi-finished product silo is connected to several conveying mechanisms. Each outlet of the semi-finished product silo is connected to a weighing silo. A packaging mechanism is installed at the outlet of each weighing silo. The lightweight aggregate silo has several outlets. Each outlet of the lightweight aggregate silo is connected to a receiving tank via a feeding pipe. The outlet of the receiving tank is equipped with a discharge valve. The feeding pipe is equipped with a quantitative discharge valve. The inlet of each weighing silo is correspondingly provided with an outlet of a conveying mechanism and an outlet of a receiving tank.

[0006] Preferably, the lightweight aggregate bin is connected to the lightweight aggregate expansion furnace via a fourth feeding device.

[0007] Preferably, the first feeding device, the second feeding device, and the conveying mechanism are all screw conveyors.

[0008] Preferably, the third feeding device is an auger conveyor, the discharge port of the metering bin is connected to the feed end of the elevator through the auger conveyor, the discharge end of the elevator is connected to the feed end of the mixing bin, and the elevator is equipped with a small material addition bin.

[0009] Preferably, the packaging mechanism is a bag-type packaging machine.

[0010] Preferably, the mixing chamber is a horizontal drum mixer.

[0011] This invention also proposes a method for producing inorganic lightweight aggregate thermal insulation mortar, comprising the following steps: S1. The cement silo delivers a batch of mixed cement material to the metering hopper, and stops delivering the material once the specified weight is reached. S2. The sand tank conveys a batch of mixed sand to the metering chamber, and stops conveying once the specified weight is reached. S3. The metering bin transports the weighed cement raw materials and sand to the mixing bin; S4. The mixing silo mixes cement raw materials and sand, and the mixed finished material is transported to the semi-finished product silo. S5. Control the opening time of the quantitative feeding valve as needed to deliver a single bag weight of lightweight aggregate from the lightweight aggregate bin to the receiving tank. S6. The semi-finished product warehouse conveys semi-finished products to the weighing warehouse through a conveying mechanism, and stops conveying after the specified weight is reached. S7. The discharge valve of the receiving tank is opened, and the light aggregate in the receiving tank is transported to the weighing bin; S8. The discharge valve at the bottom of the weighing chamber opens, and the finished product falls into the packaging bag and is packaged by the packaging mechanism.

[0012] Preferably, the lightweight aggregate is vitrified microspheres.

[0013] The beneficial effects of this invention are: This invention first mixes a large quantity of cement and sand evenly, then weighs the mixed semi-finished product in a weighing hopper. After weighing, the required lightweight aggregate is added to each bag of product separately, and finally packaged to ensure that the content of lightweight aggregate in each bag of product is stable.

[0014] Compared with the one-pot mixing production method in the prior art, the present invention avoids the squeezing and impact of mechanical stirring on the vitrified microspheres during the production process, which not only saves energy consumed during stirring, but also ensures the heat insulation performance of the vitrified microspheres. In the finished product, the vitrified microspheres are less damaged. Under the premise of consistent raw material ratio and the same total mass of feed, the coating rate per ton of the finished product is significantly improved, and the construction area that a single bag of product can cover is greatly increased, effectively reducing the overall construction cost for end customers.

[0015] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

[0019] The lightweight aggregate bin 6 is connected to the lightweight aggregate expansion furnace 9 via the fourth feeding device 91.

[0020] After the lightweight aggregate is produced in the lightweight aggregate expansion furnace 9, it is directly conveyed through the fourth feeding device 91 without the need for intermediate storage.

[0021] The first feeding device 11, the second feeding device 21, and the conveying mechanism 51 are all screw conveyors.

[0022] The third feeding device is an auger conveyor. The discharge port of the metering bin is connected to the feed end of the elevator through the auger conveyor. The discharge end of the elevator is connected to the feed end of the mixing bin. The elevator is equipped with a small material addition bin.

[0023] The packaging mechanism is a bag-type packaging machine.

[0024] The mixing chamber 4 is a horizontal drum mixer.

[0025] This invention also proposes a method for producing inorganic lightweight aggregate thermal insulation mortar, comprising the following steps: S1. Cement silo 1 conveys a batch of mixed cement material to metering bin 3, and stops conveying after the specified weight is reached. S2, Sand tank 2 conveys a batch of mixed weight of sand to metering chamber 3, and stops conveying after the specified weight is reached; S3, Metering bin 3 transports the weighed cement raw materials and sand to mixing bin 4; S4, mixing bin 4 mixes cement raw materials and sand, and the mixed finished material is transported to semi-finished product bin 5; S5.
