Description
Technical Field
The utility model belongs to the technical field of compound processing technique and specifically relates to an integrated form processingequipment of compound is related to.
Background
Hemihydrate gypsum is the main raw material of various gypsum products in the gypsum industry. To prepare the semi-hydrated gypsum (the molecular formula is CaSO4 & 1/2H)2O), typically dihydrate gypsum (formula CaSO4 & 2H)2O) is subjected to calcination processing, namely 1.5 crystal waters in the molecular formula of the dihydrate gypsum are removed by high temperature, so that the hemihydrate gypsum is formed. Dihydrate gypsum is obtained by drying and dehydrating a gypsum raw material (which generally contains 5 to 30% of free water).
Therefore, when producing hemihydrate gypsum from a gypsum raw material containing free water, it is generally necessary to perform the following steps: drying to remove free water, calcining to remove crystal water, cooling, and removing dust and conveying materials.
The existing process for producing the compounds needing dehydration, such as semi-hydrated gypsum, and the like, is an air flow and fluidized bed two-step process, wherein an air flow drying process is adopted in the first step, and a buried pipe fluidized bed calcining process is adopted in the second step. After the semi-hydrated gypsum is processed by the process, the semi-hydrated gypsum with higher temperature needs to be cooled in a curing bin. In the air flow drying process, the pipe burying fluidized bed calcining process and the cooling process, dust removing equipment is required to be additionally arranged to remove dust generated in the three processes. However, when the compounds to be dehydrated, such as hemihydrate gypsum, are processed by the two-step process of air flow and fluidized bed, a large number of machines (more than 50 machines) need to be arranged on one production line to realize the whole production process, so that the operation process and the maintenance process are complicated.
In order to reduce the number of equipment and save energy, a steam rotary process with equipment cost two to three times higher than that of the air flow and fluidized bed two-step process can be adopted when producing the compound such as the hemihydrate gypsum and the like needing dehydration. The steam rotary process utilizes a steam heat exchange device to directly dehydrate compound raw materials such as gypsum and the like with free water content lower than 15 percent in a calcining kiln into compound finished products such as semi-hydrated gypsum and the like. The cooler can be used for cooling the finished products of the semi-hydrated gypsum and other compounds with higher temperature from the calcining kiln. Wherein, the steam condensate water generated by part of the steam can enter the steam heat exchange device, thereby saving energy. However, when the steam rotary process is used for producing the compound such as the semi-hydrated gypsum and the like which needs to be dehydrated, the dust removal equipment needs to be respectively arranged at the calcining kiln and the cooling machine to remove dust generated in the processing process, so when the steam rotary process is used for producing the compound such as the semi-hydrated gypsum and the like which needs to be dehydrated, a plurality of machines (more than about 40 machines) need to be arranged on one production line to realize the whole production process.
Therefore, when the compounds such as the semi-hydrated gypsum and the like which need to be dehydrated are produced by utilizing the two-step process of the airflow and the fluidized bed or the steam rotation process, because the dehydration process and the cooling process are respectively completed by different equipment, dust removing equipment needs to be respectively arranged in the dehydration process and the cooling process, so that a plurality of machines need to be arranged on a production line for producing the compounds such as the semi-hydrated gypsum and the like which need to be dehydrated, and great manpower and material resources need to be invested in the operation and the later maintenance process in the production process.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b):
as shown in fig. 1 to 3, the compound integrated processing device provided in the present embodiment includes a heating module 1, a refrigeration module 2, a dust removing assembly 3, and a housing 4. The interior of the housing 4 includes a dust removing space and a processing space. As shown in fig. 2, at least one partition 40 is provided in the processing space of the casing 4, and the partition 40 partitions a calcining chamber 41 and a cooling chamber 42 in the processing space of the casing 4. The heating module 1 is arranged at the calcining chamber 41 and is used for heating the material entering the calcining chamber 41 so as to dehydrate the material in the calcining chamber 41. The refrigeration module 2 is arranged in the cooling chamber 42 and is used for cooling the material entering the cooling chamber 42. The dust removing assembly 3 is installed in a dust removing space of the housing 4 and is used for removing dust in the housing 4.
When producing a compound to be dehydrated, such as hemihydrate gypsum, using the integrated processing apparatus for a compound according to the present embodiment, a compound material containing free water or crystal water may be first fed into the calcining chamber 41, and the material may be dehydrated in the calcining chamber 41 using the heating module 1. In the dehydration step, the above-mentioned material is heated and dehydrated to a desired state, that is, after the material is heated and dehydrated in the calcining chamber 41 to obtain a desired compound such as hemihydrate gypsum, the desired compound such as hemihydrate gypsum having a relatively high temperature is transferred to the cooling chamber 42 to perform a cooling step of the desired compound such as hemihydrate gypsum. In the cooling step, the temperature of the compound such as hemihydrate gypsum is lowered to a predetermined temperature by the refrigeration module 2 in the cooling chamber 42.
As shown in fig. 4, the heating module 1 may be a heat exchanger, and a heat source of the heat exchanger uses a heat medium such as steam or heat transfer oil.
In the existing two-step process of airflow and fluidized bed, the buried pipe fluidized bed calcining process is to use a built-in heat pipe fluidized bed as a buried pipe fluidized bed, and hot flue gas is introduced into the built-in heat pipe, so that the material is calcined by utilizing the heat exchange between the hot flue gas and the material. But the heat exchange coefficient between the hot flue gas and the materials is lower, the heat transfer in unit area is less, the energy consumption is high, and the calcining efficiency is low. And the heat source of the heating module 1 provided by the embodiment adopts heating media such as steam or heat conduction oil, and the like, so that the heat exchange coefficient is higher and the calcining efficiency is higher compared with that of hot flue gas.
Further, the heat exchanger is detachably installed in the calcining chamber 41. The detachable installation mode can reduce the maintenance difficulty and cost of the heat exchanger, and further can prolong the service life of the integrated processing device of the compound.
The refrigeration module 2 may be a cooler, and a refrigerant such as chilled water may be introduced into the cooler. The coolant in the cooler can cool the hemihydrate gypsum with a relatively high temperature to a desired temperature.
Further, the cooler is detachably installed in the cooling chamber 42. The detachable installation mode can reduce the maintenance difficulty and cost of the cooler and further prolong the service life of the integrated processing device of the compound.
Compared with the prior art, the calcining chamber 41 and the cooling chamber 42 in the compound integrated processing device provided in the embodiment are both in one housing 4, that is, the dehydration process and the cooling process are both performed in one housing 4, so that both the dust generated in the dehydration process and the dust generated in the cooling process can be removed by the dust removing assembly 3 in the housing 4, without providing one dust removing assembly 3 for each of the dehydration process and the cooling process. The integrated processing device of compound that this embodiment provided carries out dehydration process, cooling process and dust removal process integration in a casing 4, can simplify the production process of compounds such as hemihydrate gypsum to and can reduce the quantity of dust collecting equipment, and then can reduce the operation in the production process and the manpower and material resources that input in the later stage maintenance process.
It can be seen that the integrated processing device for the compound provided by the embodiment alleviates the technical problem that when the compound needing to be dehydrated, such as hemihydrate gypsum, is produced by using an air flow + fluidized bed two-step process or a steam rotation process in the prior art, because the dehydration process and the cooling process are respectively completed by different equipment, dust removing equipment needs to be respectively arranged in the dehydration process and the cooling process, so that a plurality of machines need to be arranged on a production line for producing the compound needing to be dehydrated, such as hemihydrate gypsum, and the like, and great manpower and material resources need to be invested in the operation and the later maintenance process in the production process.
As shown in fig. 2, the partition 40 is plural, and the plural partitions 40 are provided in the processing space of the housing 4 at intervals to divide the processing space of the housing 4 into at least three chambers. The at least three chambers include at least one drying chamber 43, at least one calcining chamber 41, and at least one cooling chamber 42. The calcining chamber 41 is located between the drying chamber 43 and the cooling chamber 42. The drying chamber 43 is connected with a drying module, and the drying module is used for accelerating the evaporation of water in the material in the drying chamber 43.
The existing steam rotary process is to concentrate drying and calcining in a calcining kiln, and in the concentrated drying and calcining process, the free water content in compounds such as gypsum raw materials is higher than 15%, so that the compounds such as the gypsum raw materials are adhered to the wall in the calcining kiln, and the product quality of the semi-hydrated gypsum is reduced. Therefore, before calcining the compounds such as the gypsum raw materials, the compounds such as the gypsum raw materials are dried to reduce the content of free water, thereby effectively preventing the compounds such as the gypsum raw materials from sticking to the wall in the calcining stage.
Taking the production of semi-hydrated gypsum, the material is the gypsum raw material as an example, when the semi-hydrated gypsum is produced by using the integrated processing device of the compound provided by the embodiment, the gypsum raw material can be put into the drying chamber 43 first, the moisture evaporation in the gypsum raw material is accelerated by using the drying module, and part of free water in the gypsum raw material is removed. After the free water content in the gypsum raw material is reduced, the gypsum raw material is sent into a calcining chamber 41, and crystal water in the gypsum raw material is removed by using a heating module 1, so that the gypsum raw material is calcined into semi-hydrated gypsum. After the hemihydrate is made, the hemihydrate is then sent to the cooling chamber 42 with a higher temperature, and the temperature of the hemihydrate is lowered by the action of the refrigeration module 2, and the hemihydrate can then be sent out to a package or storage.
It can be seen that the drying chamber 43 and the drying module are used to dehydrate the free water in the gypsum raw material, so that the content of the free water in the gypsum raw material is reduced, thereby facilitating the next calcination process of the gypsum raw material.
In addition, since the drying chamber 43, the calcining chamber 41 and the cooling chamber 42 are all located in the processing space in the housing 4, the dust removing assembly 3 in the dust removing space in the housing 4 can be always in an operating state during the drying and calcining processes of the gypsum raw material and during the temperature lowering process of the hemihydrate gypsum, and dust generated in the three processes can be removed.
Compared with the existing semi-hydrated gypsum production process, the integrated processing device for the compound has the advantages that the drying, calcining, cooling and dedusting functions are integrated in one shell, the number of machines on a gypsum production line can be reduced, the occupied area of the machines in the gypsum production line can be reduced, the investment cost is effectively reduced, the operation and maintenance process is easy to carry out, and the operation cost and the maintenance cost are reduced.
As shown in fig. 2, the number of the calcining chambers 41 may be plural, a plurality of the calcining chambers 41 are sequentially distributed, and the plurality of the calcining chambers 41 are located between the drying chamber 43 and the cooling chamber 42. Wherein, each calcining chamber 41 is provided with a heating module 1, and a plurality of heating modules 1 can be arranged in one calcining chamber 41 according to different capacities. In the process of calcining the gypsum raw material, the gypsum raw material can be sequentially put into the calcining chambers 41, and the calcining time of the gypsum raw material can be ensured by the calcining chambers 41, so that the production quality of the semi-hydrated gypsum can be improved.
The drying chamber 43 and the cooling chamber 42 may be provided in plural numbers, and the plural drying chambers 43 may be distributed in sequence and the plural cooling chambers 42 may be distributed in sequence. One or more refrigeration modules 2 may be disposed within each cooling compartment 42.

The drying chamber 43 and the calcining chamber 41 are both provided with hot air ports 44, and the hot air ports 44 on the drying chamber 43 and the hot air ports 44 on the calcining chamber 41 are respectively communicated with the drying module. The drying module is used for supplying hot air to the drying chamber 43 to blow the material in the drying chamber 43 into the calcining chamber 41, and supplying hot air to the calcining chamber 41 to blow the material in the calcining chamber 41 into the cooling chamber 42.
The hot air assembly 5 comprises a blower 50 and a heater 51, the blower 50 is communicated with the heater 51, the blower 50 can pressurize gas, and the pressurized gas is heated into hot air after passing through the heater 51. The hot air can flow to the hot air ports 44 on the drying chamber 43 and the hot air ports 44 on the calcining chamber 41, and enter the drying chamber 43 and the calcining chamber 41.
The hot air introduced into the drying chamber 43 through the hot air port 44 of the drying chamber 43 can fluidize the gypsum material in the drying chamber 43, and the gypsum material in the drying chamber 43 is dried by the hot air and can flow to the calcining chamber 41 adjacent to the drying chamber 43 through the partition plate 40 after being dried.
The hot air introduced into the calcining chamber 41 through the hot air ports 44 of the calcining chamber 41 can fluidize the gypsum material calcined by the heating module 1 in the calcining chamber 41, and at this time, the gypsum material in the calcining chamber 41 can cross the partition 40 by the hot air and flow into the calcining chamber 41 adjacent to the calcining chamber 41 or the cooling chamber 42. If the gypsum raw material is introduced into the calcining chamber 41 adjacent to the calcining chamber 41 in which the gypsum raw material is located, the operation of the hot air unit 5 is repeated until the gypsum raw material in the calcining chamber 41 is fluidized by being blown up and passed over the partition 40 into the cooling chamber 42.
The hot air unit 5 operates in a similar manner to the conventional ebullated bed, and can sequentially transfer gypsum raw materials among the drying chamber 43, the calcining chamber 41, and the cooling chamber 42. Therefore, the hot air component 5 not only can heat the gypsum raw material, so that the gypsum raw material can be dried conveniently and the calcining process of the gypsum raw material is accelerated, but also can convey the gypsum raw material.
It can be seen that the hot air assembly 5 in the integrated processing device for compound provided by the embodiment can further reduce the number of machines on a gypsum production line, reduce the equipment cost and reduce the manpower and material resources required by the operation and maintenance process.

Wherein, first air distribution plate 45 plays the effect of equipartition hot-blast for the gypsum raw materials can be by more even drying or calcination, and then can promote the product quality of hemihydrate gypsum.
In practical application, the first air distribution plate 45 can be an air distribution plate used in the existing semi-hydrated gypsum production process, and the through holes on the first air distribution plate can allow hot air to pass through but can prevent gypsum raw materials from passing through.
