Abstract

Method and arrangement for automatic mixing of water and concrete for rock bolting including adding water and concrete to a mixing vessel (1), mixing the water and concrete, and transferring the water and concrete to a drill hole(2). Water amount and concrete amount for the mixture of water and concrete is calculated in a control unit (3), that the calculated water amount is added to the mixing vessel (1), that the in the reality added water amount is weighed (4), that the calculated concrete amount is corrected considering the in the reality added water amount to obtain a correct mixture of water and concrete, that concrete and water are mixed during a predetermined time, and in that the mixture of water and concrete is transferred to a drill hole (2).

Description

ul OI I 0 0 000 0000 to n 0 1 1 I 000 In on :coca A4002bas,doc 526 474 2 Den på ritningen visade anordningen fungerar på följande sätt. Först ställer operatören in det önskade viksförhållandet mellan cement och vatten och önskad total vikt för blandningen om inte hela blandningskärlets 1 volym önskas. Dessa värden lagras i styrenheten 3. Styrenheten 3 beräknar därefter de önskade vikterna cementoch vatten utgående antingen den önskade vikten på den färdiga blandningen eller från blandningskärlets 1 volym. Blandningen börjar genom att mängden vatten och cement vägs medelst vågen 4. I det visade exemplet står blandningskärlet 1 på vågen 4. ul OI I 0 0 000 0000 to n 0 1 1 I 000 In on: coca A4002bas, doc 526 474 2 The device shown in the drawing works as follows. First, the operator sets the desired folding ratio between cement and water and the desired total weight of the mixture unless the entire volume of the mixing vessel 1 is desired. These values are stored in the control unit 3. The control unit 3 then calculates the desired weights of cement and water based on either the desired weight of the finished mixture or from the volume of the mixing vessel 1. The mixing begins by weighing the amount of water and cement by means of the scale 4. In the example shown, the mixing vessel 1 is on the scale 4.

Blandningskärlet 1 kan naturligvis vara upphängt, exempelvis i en lastcell. Vattnet tillförs snabbt från källan 16 till ungefär önskad mängd. Därefter beräknas cementmängden åter för att ta hänsyn till den verkliga vattenmängden. Cementen tillförs blandningskärlet 1 medelst mataren 12, exempelvis en skruvmatare. Därefter startas motorn 15 för drift av omröraren 13 en förutbestämd tid inställd i styrenheten 3. När blandningen utförts tillförs vattencementblandningen till borrhålet 2 medelst pumpen 14.The mixing vessel 1 can of course be suspended, for example in a load cell. The water is supplied quickly from the source 16 to approximately the desired amount. Then the amount of cement is calculated again to take into account the actual amount of water. The cement is fed to the mixing vessel 1 by means of the feeder 12, for example a screw feeder. Thereafter, the motor 15 for starting the agitator 13 is started for a predetermined time set in the control unit 3. When the mixing has been carried out, the water-cement mixture is supplied to the borehole 2 by means of the pump 14.

När vattencementblandningen tillförts borrhålet 2 måste blandningskärlet 1 och övrig utrustning rengöras för att förhindra att utrustningen förstörs vid arbetsavbrott. Detta görs genom att vatten tillförs blandningskälet 1 tills vattennivån 5 när en övre, inställbar gräns.When the water-cement mixture has been added to the borehole 2, the mixing vessel 1 and other equipment must be cleaned to prevent the equipment from being destroyed in the event of a work interruption. This is done by adding water to the mixing vessel 1 until the water level 5 reaches an upper, adjustable limit.

Omröraren 13 och pumpen 14 körs under hela rengöringsprocessen. Vattennivån 5 bestäms med hjälp av vågen 4. När vattennivån 5 nått en undre gräns fylls blandningskärlet 1 åter till den övre nivån. Detta förfarande upprepas ett förutbestämt antal gånger eller under en förutbestämd tid. När rengöring genomförts stängs utrustningen av och blandningskärlet 1 töms. Hela processen styrs av styrenheten 3. En fördel med detta förfarande är att det automatiskt så att operatören kan lämna utrustningen och utföra andra sysslor samtidigt som rengöringen genomförs.The stirrer 13 and the pump 14 are run during the entire cleaning process. The water level 5 is determined by means of the scale 4. When the water level 5 has reached a lower limit, the mixing vessel 1 is filled again to the upper level. This procedure is repeated a predetermined number of times or for a predetermined time. When cleaning has been completed, the equipment is switched off and the mixing vessel 1 is emptied. The whole process is controlled by the control unit 3. An advantage of this procedure is that it is automatic so that the operator can leave the equipment and perform other tasks at the same time as the cleaning is carried out.
