[0003] The purpose of the utility model is to provide a bulk cement weighing device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bulk cement weighing device, comprising a base plate, a filter cartridge, a cylinder body and a box body, a slide rail is fixed in the middle of the top surface of the base plate, a box body is fixed on the side of the top surface of the base plate, a first cavity is opened at the inner bottom end of the box body, a second cavity is opened at the inner top end of the box body, a frame is fixed on one side of the interior of the second cavity, a filter cartridge is inserted into the interior of the frame, the outer top end of the filter cartridge is connected to the input end of the fan through a second pipe, and the fan is fixed on the other side of the interior of the second cavity.

[0005] When using a bulk cement weighing device in the present technical solution, the staff needs to first connect the power supply to the utility model, control the operation of the utility model through the control panel, and the staff puts the bag to be loaded with cement on the first bracket. After putting it, the staff controls the slide rail to move the first bracket to the first cavity opened in the box body. After moving to the inside, the second bracket will be moved out of the first cavity. At this time, the staff controls the switch of the silo to transport the cement to the inside of the bag supported by the first bracket through the material pipe. When the cement is being transported, the staff can put the next bag to be loaded with cement on the second bracket. In this way, the bag supported in the first bracket is filled with cement and moved out of the first cavity. After that, the bag erected on the second bracket can immediately enter the first cavity to load cement, completing seamless operation. When cement is poured into the bag, dust will be generated, which will be sucked into the accretion hood and transmitted to the interior of the filter cartridge through the first pipe, and filtered by the filter installed in the filter cartridge. The filtered air will be transmitted to the interior of the fan through the second pipe, and finally the fan will discharge the filtered air through the third pipe. When the filter in the filter cartridge needs to be cleaned, the staff will remove the filter cartridge from the frame and take it out from the inside of the second cavity. After taking it out, the staff will turn the cartridge cover to separate it from the cartridge body. After separation, the staff can take out the filter installed in the cartridge body and clean it for subsequent use.

[0006] Preferably, the output end of the fan is connected to a third pipe, and a material pipe is installed through the middle of the second cavity. By installing the fan, the cement dust raised in the first cavity can be sucked into the filter cartridge for filtering, achieving the effect of generating negative pressure suction. The installation of the material pipe allows the cement in the silo to be transferred to the first cavity through it, providing a transmission channel.

[0007] Preferably, sealing curtains are connected to both sides of the exterior of the box, and a visual window is embedded in the front surface of the exterior of the box. The installation of the sealing curtain prevents dust generated by loading cement in the first cavity from leaking out through the two sides of the box, and the installation of the visual window allows the staff to see the cement loading situation inside the box from outside the box.

[0008] Preferably, the outer bottom end of the filter cartridge is connected to the top end of the accretion hood through a first pipe, and the accretion hood is fixed to the inner top end of the first cavity. Through the cooperation of the first pipe and the accretion hood, the dust generated in the first cavity can be gathered, inhaled and transmitted to the filter cartridge through this, achieving the effect of gathering, inhaling and transmitting.

[0009] Preferably, the filter cartridge is provided with a body inside, and a clamp is fixed to one end of the outside of the body. The installation of the clamp enables the body to be placed vertically inside the frame, achieving a position-limiting clamping effect.

[0010] Preferably, a slot is provided at one end of the cylinder body, a filter screen is provided inside the slot, and a cylinder cover is provided at the other end of the cylinder body. The slot allows the filter screen to be inserted and installed inside, which is convenient for early installation and later removal. The cylinder cover allows the filter cylinder as a whole to be disassembled, which is convenient for the staff to install and remove the filter screen installed in the cylinder body.

[0011] Preferably, a first bracket is provided in the middle of the surface of the slide rail, a second bracket is provided at one end of the surface of the slide rail, and a weight sensor is provided inside the bottom of the second bracket and the first bracket. Through the cooperation of the first bracket and the second bracket, two bags loaded with cement can be placed on the surface, achieving the effect of rotating into the box to load cement, and the installation of the weight sensor allows the staff to set the weight value of the quantitative cement through the control panel. When the quantitative weight value is reached, the weight sensor will send an electrical signal to the control panel, and the control panel will control the switch in the silo to close, preventing the cement from being discharged from the material pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model utilizes a slide rail to rotate the two brackets to the inside of the box. When the pocket on one bracket is loading cement, the other one can be put down by the staff to be prepared. This seamless operation saves time and improves work efficiency. The dust generated by loading cement in the box will be sucked into the filter cartridge for filtering and treatment, avoiding being emitted to the outside and inhaled by the staff.
