Show information that is not in another table

I am trying to bring data that is not found in another table with codeigniter

My model:

public function getEntradas($proveedor){
            //Mostrar entradas del proveedor que no estan en pagos
            $this->db->select('e.id,e.cajas,e.peso,e.status,e.hora,e.fecha,h.nombre as nombre_huerta,r.nombre as nombre_proveedor');
            $this->db->from('entrada e');
            $this->db->distinct();
            $this->db->join('pagos p','e.id != p.identrada');
            $this->db->where('e.idproveedor',$proveedor);
            $this->db->join('huerta h','e.idhuerta = h.id');
            $this->db->join('proveedor r','e.idproveedor = r.id');
            $this->db->order_by('e.id','desc');
            $result = $this->db->get();
            return $result->result();
}

This shows me all the information the id 246 is already in my table pagos therefore it should not be displayed.

If this line is modified:

$this->db->join('pagos p','e.id != p.identrada');

by:

$this->db->join('pagos p','e.id = p.identrada');

It only shows me the 246 the inverse if it applies the logic but because it does not work the !=

My tables:

SQL generated code:

    SELECT DISTINCT 
'e'.'id', 'e'.'cajas', 'e'.'peso', 'e'.'status', 'e'.'hora', 'e'.'fecha', 
'h'.'nombre' as 'nombre_huerta', 
'r'.'nombre' as 'nombre_proveedor' 
FROM 'entrada' 'e' 
INNER JOIN 'pagos' 'p' ON 'p'.'identrada' != 'e'.'id' JOIN 'huerta' 'h' ON 'e'.'idhuerta' = 'h'.'id' JOIN 'proveedor' 'r' ON 'e'.'idproveedor' = 'r'.'id' WHERE 'e'.'idproveedor' = '79' ORDER BY 'e'.'id' DESC
