Description
Technical field
The utility model belongs to dry mortar making equipment technical field, particularly relates to a kind of dry powder and mortar porous isolation-proof device.
Background technology
Dry-mixed mortar has and improves the advantages such as the superior and social benefit of conveying efficiency, energy-conserving and environment-protective, guarantee cement workability is good, therefore obtains government and payes attention to and policy support.In the discharge process of dry-mixed mortar pneumatic conveying, because the density of composition various in dry-mixed mortar, grain size are different, critical fluidization velocity is caused also to have very big difference, upper and lower layering in fluidization process, segregation effect is produced in discharge process, cement and the grains of sand flow out from discharge port respectively, break original proportioning completely, affect the performance of mortar.In addition, domestic dry-mixed mortar pneumatic transported substance flow device lagging in development, existing isolation-proof device is all based upon and strengthens disturbance or shortening fluidisation time in fluidisation storehouse, improve on the basis of mixing of materials degree in fluidisation storehouse, although preventing from playing a role in segregation, but discharging ratio can't be kept well, thus limit comprehensive use of dry-mixed mortar.
Dry-mixed mortar segregation is in transit caused to mainly contain 3 factors: the 1) segregation of when filling with substance generation.Particle diameter and the density of dry-mixed mortar different material are different, the impact being subject to air resistance in free-falling body process is also different, falling speed difference produces segregation, and the slope angle of repose of various material is not identical yet simultaneously, and the downslide angle difference on domatic also can produce certain segregation.2) in transportation, Vehicular vibration is on the impact of dry-mixed mortar.3) discharge way of Geldart-D particle itself be the most basic be segregated into because of.In dry-mixed mortar material some grain diameter or density smaller, to critical fluidization velocity require lower, other to critical fluidization velocity require higher, be relatively not easy fluidisation; Therefore, when a part of particle enters fluidization, not easily the particle of fluidisation does not also enter people's fluidized state, can be sunken to bottom.Along with air-flow velocity strengthens, after various particle all enters fluidization, there is the particle of identical requirement to flock together to fluidizing velocity, be divided into different levels, thus form more serious segregation.
In current art, for anti-segregation process, each producer mainly pays close attention to the improvement of aspect in anti-segregation such as finished bin main body, charging threeway and feeder hopper at present, and adopts the structures such as anti-segregation elephant trunk.Although these improve and structure can play a role to the anti-segregation of dry-mixed mortar to a certain extent, but in the middle of reality, material is kept in the process of bucket and transfer thereof at finished product and be there occurs segregation, even if so just make the part segregation phenomenon transferred to existing for the mortar product of finished bin also be difficult to eliminate by modified node method.
Summary of the invention
The utility model provides a kind of dry powder and mortar dryer, propose material and to keep at finished product in the process of bucket and transfer thereof to solve in above-mentioned background technology and emanate, even if the part segregation phenomenon making to transfer to existing for the mortar product of finished bin is also difficult to the problem of elimination by modified node method.
The technical matters that the utility model solves realizes by the following technical solutions: the utility model provides a kind of dry powder and mortar porous isolation-proof device, it is characterized in that: comprise isolation-proof device, fluidisation storehouse, inner core, urceolus, plate, drive motor, reducing motor, spiral butterfly valve, discharge pipe, air distribution plate, hand operated gate valve, dumping pit, control setup, sensor, hanger, flange, isolation-proof device is surrounded outside described fluidisation storehouse, described plate is positioned at the middle and lower part of isolation-proof device, described flange is positioned on the upside of isolation-proof device, described hanger is positioned at flange both sides, described isolation-proof device inside is provided with inner core, described urceolus is positioned at isolation-proof device inside, described control setup is positioned on the right side of isolation-proof device, described discharge pipe is positioned at isolation-proof device lower right side, described inner core inside is provided with multiple dumping pit, described dumping pit is cylindricality and multiple longitudinal arrangement, described sensor is positioned at outside inner core, multiple dumping pit is provided with in described urceolus, one end of described plate is provided with hand operated gate valve, the upper right side of described discharge pipe is provided with air distribution plate, described drive motor is positioned at discharge pipe lower left, described spiral butterfly valve is positioned at below drive motor, described reducing motor is positioned at below spiral butterfly valve.
The diameter of described discharge pipe is 100mm, mouth of pipe sectional area 7850mm
2.
Described inner core is positioned at inside urceolus.
Described air distribution plate is in fluidisation storehouse.
The beneficial effects of the utility model are:
1 this patent, by improving discharge port structure, changes traditional single port discharging into porous discharging, and the discharging of differing heights is synchronously carried out, and avoids segregation effect to the impact of discharge process.
The opening diameter of 2 this patent design porous discharge tubes, ensure the even of discharge process, the method combined with analytical Calculation by simulation calculation obtains the area of each discharge port on porous discharge tube, guarantees the accurate of discharging ratio, thus ensure the performance of dry-mixed mortar, there is higher using value.
In 3 this patents, flow dynamics analysis has been carried out to each dumping pit, draw the relation of fluidization environment under shed size and discharging quantity, by ensureing the synchronous discharging in each hole to the design of position of opening and diameter, realize the discharging simultaneously of each plane, eliminate the factor that on vertical direction, dry-mixed mortar material is uneven, eliminate the impact that segregation phenomenon is uneven on discharging, improve discharging effect; The method combined with analytical Calculation by simulation calculation obtains the area of each discharge port on porous discharge tube, guarantees the accurate of discharging ratio, ensures the performance of dry-mixed mortar.
In 4 this patents, tubular discharge port has opening at differing heights, the discharging while of upper and lower, regulate perforate ratio and size just can ensure that the dry-mixed mortar dumping out can keep correct proportioning from start to finish by drive motor, and sleeve has motor to drive, position of opening can be regulated at any time, ensure the dumping pit only opening below fluidization liquid level, avoid air directly to flow out, thus ensure discharging efficiency.This apparatus structure is succinct, and little to the flow in fluidisation storehouse, the device that can also improve with other storehouse inner structures jointly uses and do not clash, and eliminates segregation phenomenon further.
5 this patents design plates and hand operated gate valves, make operating personal that hand operated gate valve can be utilized to control the discharge that finished product keeps in finished product in bucket, and this mounting structure very compact on the whole, is easy to assembling.
The control setup of 6 this patents can control discharge rate, and display discharging situation, the use of convenient operation personnel.
