Description

Technical Field

[0001] The utility model relates to the technical field of valves for feeding devices, in particular to a roller press feeding device with a four-cylinder two-way flat valve. Background Art

[0002] At present, the roller press is the main equipment in the pre-grinding system of the cement production line. The flat valve of the feeding device is an important equipment in the operation control of the roller press. The roller press uses the principle of high-pressure material layer crushing and adopts a single-particle crushing group working mode to work continuously. In the production process, many factors such as large roller gap deviation, large current deviation, high bearing temperature, and large pieces of material can easily cause the roller press to trip. The original feeding device uses an electro-hydraulic one-way gate valve. When the roller press trips, due to the presence of large pieces of material and aggregate agglomeration at the gate, the gate is not closed tightly and cannot quickly cut off the material. It needs to be closed manually. After the roller press is running, the gate valve needs to be opened manually. The roller press and the gate cannot be opened at the same time, which may cause the roller press to get stuck or the roller press to be empty. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a roller press feeding device with a four-cylinder two-way flat plate valve to solve the above-mentioned problems.

[0005] The hydraulic oil cylinder comprises an oil cylinder and a push rod, the end of the push rod is connected to the valve plate through a fixing block, and the end of the oil cylinder is fixed on the valve body housing.

[0006] Open slots are arranged on both sides of the valve body shell, and the connection between the valve plate and the fixing block passes through the open slots.

[0007] Rollers are arranged at the bottom of both ends of the valve plate, and rolling grooves are arranged in the material discharge pipe and the valve body shell corresponding to the rollers, which is more conducive to the opening and closing of the valve plate.

[0008] The motor is connected to the roller press through a travel switch. After the roller press stops working, the travel switch is turned on to control the operation of the motor. The oil tank assembly works to close the valve plate through the hydraulic cylinder.

[0009] The material discharge pipeline is provided with material pipe interfaces at the top and bottom, and a material guide plate is provided above the middle valve plate of the material discharge pipeline. The material guide plate can prevent the material from entering the rolling groove and affecting the opening and closing of the valve plate during discharge.

[0010] The beneficial effects of the utility model are: materials are discharged evenly from the middle of the two-way flat valve, the four-cylinder two-way flat valve opens and closes more quickly and flexibly, the start and stop of the roller press controls the opening and closing of the valve plate through the stroke switch, avoiding the delay problem of manual opening and closing; a guide plate is provided at the valve plate discharge pipe so that the material does not directly contact the valve body and the valve plate during discharge, which better extends the service life of the valve, and a roller is installed on the valve plate to enable the valve plate to move flexibly and open freely.
