Description

Technical Field

[0001] The utility model relates to the technical field of nano calcium carbonate preparation, in particular to a powerful carbonizer for preparing nano calcium carbonate. Background Art

[0002] Nano calcium carbonate is also known as ultrafine calcium carbonate, with an average particle diameter of about 40nm. In process laboratories, ultrafine calcium carbonate is usually prepared by carbonization, double decomposition, and microemulsion. In industry, carbonization is generally used. The best carbonization method is continuous spraying. Continuous spraying is also used to produce nano calcium carbonate through carbonization. The steps are to spray Ca(OH)2 slurry from the top of the carbonization tower through a pressure nozzle in a mist form. At the same time, CO2 or a mixture of CO2 and air is introduced from the bottom of the tower to make the sprayed Ca(OH)2 slurry fully contact with CO2 and react. This method significantly increases the contact area between CO2 gas and Ca(OH)2 slurry. The reaction process can be controlled by controlling the concentration of lime milk, droplet diameter, flow rate, reaction gas-liquid ratio and other conditions to produce nano calcium carbonate with a diameter of 0.04-0.08μm at room temperature.

[0003] The nozzle of the existing powerful carbonizer prepared by nano-calcium carbonate is very easy to get clogged, and the clog cannot be automatically cleaned. A new nozzle needs to be replaced, and the maintenance cost is high; the lime milk sprayed by the existing powerful carbonizer prepared by nano-calcium carbonate does not completely react with carbon dioxide and will be mixed in the prepared nano-calcium carbonate, which is often wasted and cannot be fully contacted with carbon dioxide again for further purification. Therefore, in view of the above problems, a powerful carbonizer prepared by nano-calcium carbonate is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a powerful carbonizer made of nano calcium carbonate to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A powerful carbonizer for preparing nano calcium carbonate comprises an outer shell, a water filter net is provided at the bottom end of the outer shell, an inclined plate is fixedly connected at the edge of the bottom end of the outer shell, a discharge port is provided on the outer side of the inclined plate, a sealing cover is spirally connected inside the discharge port, an end of the inclined plate away from the outer shell is fixedly connected to a connecting plate, an air outlet pipe is provided inside the connecting plate, an air outlet hole is provided on the outer side of the air outlet pipe, a water retaining block is provided at the top of the air outlet pipe, a water storage tank is fixedly connected to the top end of the outer shell, a feed pipe is fixedly connected to the top end of the water storage tank, a water spray pipe that runs through the outer shell is fixedly connected to the bottom end of the water storage tank, a spray head is fixedly connected to the bottom end of the spray head, a water spray port is provided, a spring located above the water spray port is fixedly connected inside the spray head, a fixing plate is fixedly connected to the top end of the spring, and a cleaning needle located outside the spring is fixedly connected to the bottom end of the fixing plate.

[0007] Preferably, the outer side of the shell is fixedly connected to a connecting pipe located outside the water filter net, the end of the connecting pipe away from the shell is fixedly connected to a water pump, the top of the water pump is fixedly connected to a water pipe, and the end of the water pipe away from the water pump is fixedly connected to a water tank.

[0008] Preferably, the connecting pipe, the water pump and the water pipe form a group, there are two groups in total, and they are symmetrically arranged on the surface of the outer shell with the outer shell as the center.

[0009] Preferably, the spring and the fixing plate form a group, with three groups in total, and are evenly arranged inside the nozzle.

[0010] Preferably, there are several cleaning needles, which are evenly arranged on the surface of the fixing plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the lime milk solution entering through the water spray pipe enters the nozzle through the water spray pipe and is finally sprayed out from the water spray port. The lime milk will push the fixed plate at the moment of spraying, and the fixed plate pushes the cleaning needle into the inside of the water spray port to clean the water spray port to prevent blockage. When the lime milk stops spraying, the fixed plate drives the cleaning needle to rebound together under the action of the spring to complete the cleaning. The cleaning needle is much smaller than the diameter of the water spray port and will not completely block the water spray port to affect the spraying of lime milk liquid from the water spray port, thereby solving the problem that the nozzle of the existing strong carbonizer prepared by nano calcium carbonate is very easy to be blocked, the blockage cannot be automatically cleaned, and a new nozzle needs to be replaced, which has a high maintenance cost.

[0013] 2. In the utility model, by means of the water filter net, shell, connecting pipe, water pump, water pipe and water storage tank and other components, the nano calcium carbonate mixed with the unreacted lime milk liquid will fall to the bottom of the shell under the action of the inclined plate, and the excess lime milk can be filtered and discharged into the connecting pipe through the water filter net, and the lime milk is re-transmitted to the water storage tank through the connecting pipe, water pump and water pipe, and sprayed out through the nozzle to react with carbon dioxide again to avoid waste, thereby solving the problem that the lime milk sprayed out by the strong carbonizer for preparing existing nano calcium carbonate does not completely react with carbon dioxide and will be mixed in the prepared nano calcium carbonate, which is often wasted and cannot be fully contacted with carbon dioxide again for further purification.

[0022] The outer side of the shell 1 is fixedly connected to a connecting pipe 9 located on the outer side of the water filter net 2, the end of the connecting pipe 9 away from the shell 1 is fixedly connected to a water pump 10, the top of the water pump 10 is fixedly connected to a water pipe 11, and the end of the water pipe 11 away from the water pump 10 is fixedly connected to a water tank 12, the connecting pipe 9, the water pump 10 and the water pipe 11 are a group, there are two groups in total, and they are symmetrically arranged on the surface of the shell 1 with the shell 1 as the center, the spring 17 and the fixing plate 18 are a group, there are three groups in total, and they are evenly arranged inside the nozzle 15, and the number of cleaning needles 19 is several, and they are evenly arranged on the surface of the fixing plate 18.

[0023] Working process: when a strong carbonizer prepared with nano calcium carbonate is needed, firstly, it is poured into the water storage tank 12 through the feed pipe 13, and then the lime milk solution coming in through the water spray pipe 14 enters the nozzle 15, and finally is sprayed out from the water spray port 16. The moment the lime milk is sprayed out, it will push the fixed plate 18, and the fixed plate 18 pushes the cleaning needle 19 into the water spray port 16 to clean the water spray port 16 to prevent blockage.
