Abstract

The present invention discloses a cement and fly ash recovery device, which includes a water tank, multiple rows of water spray pipes, a dense mesh partition, a float control water valve, a water inlet pipe, a water pump, a water outlet pipe, a storage tank exhaust pipe, a valve, and a flexible water pipe. A pipe is led out from the top of the cement and fly ash storage tank and inserted into the bottom of the water tank of the recovery device. Water is injected into the water tank. When the cement and fly ash transport truck conveys materials into the storage tank, the dust scattered with the air enters the bottom of the recovery device through the pipe and forms bubbles in the water. The bubbles with dust are divided and broken multiple times by the dense mesh during the rising process, and finally the dust is incorporated into the water of the recovery device. The water with dust is output and utilized by the water pump through the water outlet. The present invention can effectively collect the dust scattered with the air from the storage tank, avoiding the pollution of the air environment. The present invention has the characteristics of simple structure, easy processing, reliable performance, convenient operation, and low cost.

Description

Technical Field

[0001] The present invention belongs to the technical field of building materials, and particularly relates to a device for recycling cement and fly ash. Background Art

[0002] Bulk cement and fly ash are usually widely used in daily construction. When bulk cement and fly ash are transported from a transport tanker to a storage tank by the air pressure pumping of the transport tanker, a large amount of dust will be discharged from the vent hole at the top of the storage tank during the process. The discharged dust particles are easy to spread, pollute the environment, have an adverse impact on the surrounding ecology, and also cause waste of resources. Summary of the Invention

[0003] The main object of the present invention is to provide a device for recycling cement and fly ash for the dust particles discharged when the existing bulk cement and fly ash are transported from a transport tanker to a storage tank, which can efficiently recycle the cement and fly ash carried out by the gas, reduce environmental pollution, and can be recycled into the water for concrete pouring to reduce the consumption of cement.

[0004] To achieve the above invention object, the present invention provides a device for recycling cement and fly ash, including a water tank, multiple rows of parallel spray pipes, a fine-mesh partition net, a float-controlled water valve, a water inlet pipe, a water pump, a drain pipe, a storage tank exhaust pipe, a valve, and a flexible water pipe. The water tank includes a storage tank exhaust pipe arranged on the right side of the water tank, a valve arranged on the storage tank exhaust pipe, multiple rows of parallel spray pipes arranged inside the water tank, a fine-mesh partition net arranged between the multiple rows of parallel spray pipes, a float-controlled water valve arranged on the upper part of the water tank, a multiple-way water inlet pipe arranged on the left side of the water tank, the multiple-way water inlet pipe is connected to the multiple rows of parallel spray pipes through a flexible water pipe, a drain pipe arranged at the bottom of the water tank, and a water pump and a valve arranged on the drain pipe. During use, first fill the water tank with water, connect the storage tank exhaust pipe to the storage tank exhaust port, open the valve of the storage tank exhaust pipe, the bubbles with dust are cut by the fine-mesh partition net in the water tank, so that the dust particles dissolve in the water, open the valve of the drain pipe, and discharge the water in the water tank to the designated recycling device for recycling. Currently, it is mainly recycled into the water used in the concrete mixing station to reduce the consumption of cement. This recycling process is carried out in real-time and continuously until the cement or fly ash in the storage tank is placed stably.

[0005] Preferably, the fine-mesh partition net is woven and made of metal and non-metal filaments and fabric materials, arranged on both sides of the multiple rows of parallel spray pipes, fixed with a fixed frame, and placed on the support points on both sides of the water tank. When the bubbles with dust particles encounter the fine-mesh partition net, they are cut, so that the cement and fly ash dissolve in the water.

[0006] Preferably, the multiple rows of parallel spray pipes are made by connecting multiple metal pipes or PVC pipes and other pipe fittings in parallel. Small holes are drilled on the upper and lower surfaces of the pipes within a range of 120°, so that the spraying is uniform and the contact is sufficient.

[0007] Preferably, the float-controlled water valve is arranged at the top of the water tank. The left end of the valve is fixed on the water inlet pipe, and the right end is connected to a float. Due to buoyancy, the float changes with the water level in the water tank. When the float rises, the float-controlled water valve descends to block the water source in the water inlet pipe. When the water level in the water tank drops, the float descends and lifts the float-controlled water valve to rise, releasing the water source into the water tank to ensure that the water level in the water tank is controlled in a timely manner.

[0008] Preferably, the water pump is a frequency-adjustable water pump, which can control the water outlet speed in a timely manner according to the dust dissolution rate.

[0009] Compared with the existing technology, the beneficial effects provided by the device of the present invention are as follows:

[0010] 1) The materials selected for the structure of the device of the present invention are all commonly used materials in daily life, which are convenient to obtain and have the characteristics of low cost.

[0011] 2) The main structure of the device of the present invention is a water tank, and its internal structure only includes multiple rows of parallel spray pipes and a dense mesh partition. It has the characteristics of simple structure and easy processing.

[0012] 3) The device of the present invention can quickly and effectively recover cement and fly ash. The multi-layered parallel spray pipes and the dense mesh partition overlap and intersect, enabling all dust particles to quickly dissolve in water, and having the characteristics of reliable performance.

[0013] 4) After connecting the exhaust pipe of the storage tank to the device of the present invention, only by controlling the valves on the air inlet pipe and the drain pipe can the operation of the device be completed. Therefore, it has the characteristics of convenient operation.

[0014] 5) The device of the present invention is small in size, light in weight, convenient for movement and transportation, and has the characteristics of wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS
